(Will there be? Can we hope?) There is a way to create a 32-bit version of Firefox with the plugin and to run it in compatibility mode, but I haven't gotten around to doing it yet. If you can access the code for the book, you may be able to run the applets using AppletViewer or write a little driver class to run them from the command line. If I get anywhere installing 32-bit Firefox, I'll let you know.

At Gavin's suggestion, I'm looking into creating a torrent for it. I'm also pushing a copy from my office, where we have T1 pipes, to Tim Born's server, which also has big pipes. That should finish at about 9:30am today. Then he can make it publicly available. With that in mind, you may want to wait until Eric or Tim say they've got it, and then pull it from one of them. My city is rolling out a municipal wireless program, putting WAPs all over town. I told the city IT director that what *I* want is a fiber run from my house to whatever is on the backside of the WAPs. He hasn't gotten back to me on that yet.

BT works well when many people are downloading a file, literally the more the merrier. In our case, we're a relatively small group so I wonder if the number of seeders will ever reach a critical mass. OTOH, if people outside this mailing list pick it up from linuxtracker.org, that might make a difference. I just don't know how many people will be interested.

Subject: Re: [K12OSN] Converting to Linux Levi, I think that the first thing you should do is look at the types of clients you want to convert. Get detailed information about what hardware you have now and need to support for the switch. Make a list. Chip sets, processors, memory, printers, scanners, etc. Next look at your software requirements. Does your school system require the use of any software? Is it local or web-based? If the students need to visit web pages, are they built only for IE? How many students will your lab support this year? What's your one, three and five-year plan? How resistant are your teachers to switching from Windows? Does it terrify them? How supportive is the administration for this switch? Ask these questions before you ever decide what focus to take for the switch. You may save a lot of time that you would otherwise spend trying to fit a square peg into a round hole. Once you have these questions answered, get back to us with the details, and there will be a million recommendations for you. I once put together a thin client network of thirteen machines for under US$1000, including the server. Everything was very used, but someone recently commented to me that the system used to work very well and that it was bulletproof. Best of luck in your conversion, but remember the old carpenter's rule: "Measure twice; cut once." Save yourself a lot of headaches by looking at your requirements before you start with any software. Dan On 2/24/07, Kemp, Levi wrote: I'd like to ask for suggestions on this undertaking; we are going to attempt to use Linux at our school as opposed to Windows. My first question is this, without setting up a Linux server is it possible to create a lab of Linux clients and run them on our current network, or does this have to be all or none? I'm unsure if we want to go with thin clients, some of the programs may be too much to run over the network. Second question, what version of Linux would you suggest? None of us have a great deal of experience with Linux, we are just unable to keep are hardware up with the requirements for windows and do not want to have to move into Vista.

Should I just set up > a diskless and see for myself? Yes, a recent version of Gnome or KDE is probably to much to ask for a 450 MHz with 128 MB RAM. Maybe an XFCE or a more stripped down desktop environment will work, but frankly 128 or 256 MB RAM is just not enough and it won't give a good impression of what it will be like to run thin clients. You'll need a beefy machine to show off what an LTSP client looks like or actually set up an LTSP server (with a little more than 256 MB RAM) with some clients indeed. 128 MB RAM and a 450 MHz processor should be enough for a thin client.

At 450mhz, the machines will run, but things won't be snappy. The REAL power of LTSP is when you install it on a fast, modern computer and then plug old machines in as clients and applications run via the clients run lightning fast, because they're actually running on the server, but appearing on the client. Plus, you hook up another old client and it seems fast, too. And another, and another, and so on. Understanding the concept is sometimes difficult for people who are used to thinking in Windows' "one computer for each person" terms; it's even more difficult for non-technical people to grasp, perhaps not even worth trying to explain. But show it to them and they'll get it, whether they understand it or not. As to the fast server part, the cost of fast drops daily. Right now, you can go to Best Buy and get a $600 HP box that will support 8-10 client machines. That's for a dual-core box with 1GB of RAM; add another gig of RAM for $100 and you can double the number of clients it will support. So, borrow a fast machine if you must, or bring one from home. Use at least a 7200RPM drive with 8MB cache in it (sounds like you've got this kind of drive already). Use that for the server, and use your 450mhz machines as clients to that. Then you'll see speedy performance. One more thing: When you show this off to people, be sure you've brought up the popular applications beforehand, so that they're in cached memory. The first time (after boot) an app is loaded, it will be slower because it has to be loaded from the disk. All subsequent loads will be from cache and will happen quickly, e.g., from cache, OpenOffice.org takes about 2.5 seconds to load, so that's what the clients will get.

If the system has minimal RAM (128MB is considered minimal) then heavy environments like gnome and KDE will feel sluggish. Now add that these are older IDE drives that have slow IO and very slow CPU speeds. So as far as running these old boxes as desktops, they will be slow since they are underpowered. But using them as thin clients eliminates most of these issues. All of the computational work gets done on the _server_ and the load on the client is minimal. 128MB RAM is just fine as well as the 450MHz CPU. The key there is the server has some CPU horsepower and RAM. All the client has to do is spit bits on the screen. -- James P.

Everything (Firefox, OpenOffice.org, KDE/GNOME, etc.) runs on the dual Athlon, not on the Pentium-166. It's basically a graphical dumb-terminal, like back in the mainframe "green screen" days. I agree with James; don't try running those old boxes as standalone "fat clients" like you used to do with Windows 98. The only way that would feasibly work is if you use a "micro" GNU/Linux distribution like Damn Small Linux (yes, that's its official name), which fits on a 50MB mini-CD. But that probably isn't what you're looking for. Go ahead and set up diskless. That's the way you run LTSP/K12LTSP anyway, so that's the proper demo to have. Whenever I demo K12LTSP, I *always* go diskless + server. --TP -------------- next part -------------- An HTML attachment was scrubbed...

A client starts up and randomly chooses the next available terminal server. When this happens, the user logs on to the system, the home folders are 'copied' across to the new server, and normal session login occurs. I have ONE USER (that's the odd behaviour) that can log on to serv01 but not serv02. When she logs into serv01, the home folder is created in the /home directory of serv01, and everything 'works normally.' When she tries to log into serv02 in the exact manner (with same username/password, session type, etc), she gets the message Your home directory is listed as: '/home/' but it does not appear to exist. Do you want to log in with the / (root) directory as your home directory And she can't log in (no copying of the /home folders from the LDAP server to serv02/home occurs) Any ideas of what's gone wrong for this one user, and where to look for a fix? - Ryan -------------- next part -------------- A non-text attachment was scrubbed...

Which iMacs specifically? The Bondi Blue 233Mhz iMacs work great out of the box. The other versions might need a tweaked XF86config. You need to either have a new enough version that can network boot via holding the "N" key down, or modify the firmware to boot. I just googled for instructions and found an old email from myself: ------start message clips--------- Yes, you can use an iMac as a diskless workstation. If you have changed your server IP from the default of 192.168.1.254 then you need to modify /opt/ltsp/ppc/etc/lts.conf and modify the line at the top of the file that points to your server to match the actual IP. I believe that if you are using K12LTSP version 5 this updates automatically. After that you can simply boot your iMac by holding down the "N" key on the keyboard. If that for some reason does not work, try booting with cmd+option+o+f which will bring you to a command prompt. Then at the prompt type "boot enet:192.168.1.254;yaboot" with out the quotes and the IP set to match your server IP. If either of the changes above work let us know, if you have one of the lucky ones that require the firmware command then there is a set of instructions to set it permanent. Boot with apple+option+o+f again Type the follwing at the command line: setenv boot-device enet:192.168.0.254 Hit enter. setenv auto-boot? true Hit enter. reset-all Hit enter. The machine should reboot and now automatically boot to ltsp every time it is powered up. Tip: If for some reason your machine will not boot after entering boot enet:192.168.0.254 with some error that it cannot find a boot loader or whatever, try this: boot enet:192.168.0.254,yaboot --------end message clips---------- -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

I just googled for instructions and found an old email from myself: ------start message clips--------- Yes, you can use an iMac as a diskless workstation. If you have changed your server IP from the default of 192.168.1.254 then you need to modify /opt/ltsp/ppc/etc/lts.conf and modify the line at the top of the file that points to your server to match the actual IP. I believe that if you are using K12LTSP version 5 this updates automatically. After that you can simply boot your iMac by holding down the "N" key on the keyboard. If that for some reason does not work, try booting with cmd+option+o+f which will bring you to a command prompt. Then at the prompt type "boot enet:192.168.1.254;yaboot" with out the quotes and the IP set to match your server IP. If either of the changes above work let us know, if you have one of the lucky ones that require the firmware command then there is a set of instructions to set it permanent. Boot with apple+option+o+f again Type the follwing at the command line: setenv boot-device enet:192.168.0.254 Hit enter. setenv auto-boot? true Hit enter. reset-all Hit enter. The machine should reboot and now automatically boot to ltsp every time it is powered up. Tip: If for some reason your machine will not boot after entering boot enet:192.168.0.254 with some error that it cannot find a boot loader or whatever, try this: boot enet:192.168.0.254,yaboot --------end message clips---------- -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean. _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn For more info see -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

When you hear of Linux being able to run on older thin clients where as Windows can't comes from the many options and choices out there. You can go with something like LTSP and use a server as your horsepower if you'd like. But if you just want to run local distros without getting into LTSP check out stuff like DSL (http://www.damnsmalllinux.org) or DSL-N (http://www.damnsmalllinux.org/dsl-n/). These are very small and very lightweight distros that will run circles around Windows on your machines. However the lighter weight the distro, the less eyecandy. Functionality is just as good, you can still run OpenOffice, but it may not be as appealing when trying to show others how "great" Linux is. Many users base functionality off of eye candy. But if you just want to see how fast those old machines can be, try out one of the 2 distros above. DSL-N is slightly larger but has more features and a newer kernel. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

Should I just set up a diskless and see for myself? Levi There are many factors that determine the felt speed of the system. The greatest factor is RAM. If the system has minimal RAM (128MB is considered minimal) then heavy environments like gnome and KDE will feel sluggish. Now add that these are older IDE drives that have slow IO and very slow CPU speeds. So as far as running these old boxes as desktops, they will be slow since they are underpowered. But using them as thin clients eliminates most of these issues. All of the computational work gets done on the _server_ and the load on the client is minimal. 128MB RAM is just fine as well as the 450MHz CPU. The key there is the server has some CPU horsepower and RAM. All the client has to do is spit bits on the screen. And that's why my Pentium-166 thin client feels like a dual-Athlon machine. My K12LTSP server is the dual-Athlon. Everything (Firefox, OpenOffice.org, KDE/GNOME, etc.) runs on the dual Athlon, not on the Pentium-166. It's basically a graphical dumb-terminal, like back in the mainframe "green screen" days. I agree with James; don't try running those old boxes as standalone "fat clients" like you used to do with Windows 98. The only way that would feasibly work is if you use a "micro" GNU/Linux distribution like Damn Small Linux (yes, that's its official name), which fits on a 50MB mini-CD. But that probably isn't what you're looking for. Go ahead and set up diskless. That's the way you run LTSP/K12LTSP anyway, so that's the proper demo to have. Whenever I demo K12LTSP, I *always* go diskless + server. --TP -------------- next part -------------- A non-text attachment was scrubbed...

Subject: Re: [K12OSN] Booting older thin clients Running Linux from the local hard drive won't be much different than running Windows from the local hard drive, so your experience is 'normal'. At 450mhz, the machines will run, but things won't be snappy. The REAL power of LTSP is when you install it on a fast, modern computer and then plug old machines in as clients and applications run via the clients run lightning fast, because they're actually running on the server, but appearing on the client. Plus, you hook up another old client and it seems fast, too. And another, and another, and so on. Understanding the concept is sometimes difficult for people who are used to thinking in Windows' "one computer for each person" terms; it's even more difficult for non-technical people to grasp, perhaps not even worth trying to explain. But show it to them and they'll get it, whether they understand it or not. As to the fast server part, the cost of fast drops daily. Right now, you can go to Best Buy and get a $600 HP box that will support 8-10 client machines. That's for a dual-core box with 1GB of RAM; add another gig of RAM for $100 and you can double the number of clients it will support. So, borrow a fast machine if you must, or bring one from home. Use at least a 7200RPM drive with 8MB cache in it (sounds like you've got this kind of drive already). Use that for the server, and use your 450mhz machines as clients to that. Then you'll see speedy performance. One more thing: When you show this off to people, be sure you've brought up the popular applications beforehand, so that they're in cached memory. The first time (after boot) an app is loaded, it will be slower because it has to be loaded from the disk. All subsequent loads will be from cache and will happen quickly, e.g., from cache, OpenOffice.org takes about 2.5 seconds to load, so that's what the clients will get.

And you can still use the CD drive and the floppy drive for Local Device Access (LDA). But there are some tradeoffs.

Really, the problem isn't with Firefox, but with binary plugins.

This is a case where coming in second is better than coming in first, as the first user/client to load an application has to read it from the disk, whereas the second user (and third and fourth, etc.) gets to take advantage of the cache of the app that was created when the first user started up the app. A 2ghz machine with 1GB RAM will work just fine for five clients. You could probably even handle to eight or ten clients, depending on the apps they run, etc. But for demo purposes, use five clients so that people can see how quick it is. And by the way, handling, say 10-15 clients would just be a matter of adding another gig of memory which will cost you only about $100. Try that with Windows: getting 5-8 more speedy computers for just $100. Petre Kemp, Levi wrote: > And the cache applys to all the clients together correct? Once one loads it, the cache is on the server and its saved there for all. The only available computer to temp as a server would be a 2GHz Athlon with a Gig of RAM.

If you use two NICs in the server, one for the clients, one to connect to the school network, then no, you won't have any trouble, since the server's DHCP server only hands out addresses on the NIC for the clients. But if you'll be putting your clients and server(s) all onto the schools main network, you will have problems with multiple DHCP servers handing out addresses. This is still manageable, but you have modify the ranges of addresses that each server gives out, and you might have clients connecting to different servers at each boot. Since you're new to this, I suggest keeping each room's client computers on a private network, and connect only the LTSP server to the school's existing network, just for simplicity. All the client machines will be hidden from the school network, and the server will handle all the internet-bound traffic via NAT. Petre Kemp, Levi wrote: > Thats what I wanted to here.

Asterisk is probably your best solution. If you have the available POTs lines I would purchase at least two FXS modules on the TDM400 card. This depends on the amount of calls you need to make. You will need to build a database back end to this and some type of interface. Someone might have already build a GUI for this. I have done similar stuff to this. Before you jump into anything you need to calculate how long it will take to call each person. Some things to think about; How many calls, What type of reports do you need, successful calls, failed calls do you need confirmation on the call? how long will the message be, this will directly affect the number of call you can make over a given time. hope this helps, Cory Joe OBrien wrote: This may be off topic, but does anyone know of a Linux based auto dialer for calling parents with a prerecorded message? --thx --joe o'brien --Meridian School District _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn For more info see -------------- next part -------------- An HTML attachment was scrubbed...

Booting from a server will give you the best performance. If you really want to try out a local installation, I've had pretty good success with Xubuntu 6.10 on older machines with 128MB ram. The fastest distro I've seen, I think, is Puppy Linux. It's a close call between that and Damn Small Linux (DSL). Both Puppy and DSL run completely off the CD, so you don't even have to install them--and they're still fast. -Rob On Thu, Mar 01, 2007 at 10:51:59AM -0600, Kemp, Levi wrote: > Ok I have to ask at the risk of sounding ignorent.

I trust that if we get this answered it will help out all us poor folk who are stuck with macs as thin clients. I know that with local installs of mac linux distros there is an option to emulate the second button with the mac mouse (i.e. ctrl+mouse click=right click). I haven't been able to figure out how to do this with ltsp (although I haven't really tried). I am guessing it is just an X config option.

Subject: Re: [K12OSN] Booting older thin clients Depends on what you mean by 'other systems'. If you use two NICs in the server, one for the clients, one to connect to the school network, then no, you won't have any trouble, since the server's DHCP server only hands out addresses on the NIC for the clients. But if you'll be putting your clients and server(s) all onto the schools main network, you will have problems with multiple DHCP servers handing out addresses. This is still manageable, but you have modify the ranges of addresses that each server gives out, and you might have clients connecting to different servers at each boot. Since you're new to this, I suggest keeping each room's client computers on a private network, and connect only the LTSP server to the school's existing network, just for simplicity. All the client machines will be hidden from the school network, and the server will handle all the internet-bound traffic via NAT. Petre Kemp, Levi wrote: > Thats what I wanted to here.

Both Puppy and DSL run completely off > the CD, so you don't even have to install them--and they're still fast. Okay since we are all talking about small distros I have to mention my favorite. Slax. www.slax.org. It's a 192MB (Standard Edition) Slackware based live cd that also runs off a usb stick. It's got fluxbox and kde and amazingly it actually runs a kde desktop acceptably on a 450Mhz with 196MB. With 128MB I use fluxbox perfectly. It's got a plethora of modules (extra applications) you can easily add. Best of all there is a Windows program you can download called MySlax Creator http://myslax.bonsonno.org/ where you can add extra modules to create a customized ISO and either burn it or make a bootable live USB stick. I get my students to do this. They love it. OS in your pocket. Don't get version 6 yet, it's not finished. Get 5.1.8.1 standard edition. If you are running it on a CRT monitor use the xconf command to optimize X. I am actually in the process of setting up my thin clients to dual boot with lilo to my k12ltsp server and slax on the local hd. They are PII 233 with 196MB. A really nice teaching opportunity is sshfs with Slax. Last point, Slax has a beautiful UI unlike other small distros. Did I mention it's got ntfs write support and version 6 will have out-of-the-box wifi ndiswrapper setup. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From microman at cmosnetworks.com Fri Mar 2 06:11:34 2007 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Fri, 02 Mar 2007 01:11:34 -0500 Subject: [K12OSN] cups question In-Reply-To: <20070228153257.M3611@winonacotter.org> References: <362115.71407.qm@web35210.mail.mud.yahoo.com> <20070228153257.M3611@winonacotter.org> Message-ID: <45E7C016.3080208@cmosnetworks.com> Jim Kronebusch wrote: > On Mon, 26 Feb 2007 10:05:17 -0800 (PST), James Huffman wrote > >> Hello all! >> I have a (hopefully) easy cups question.

But what if you could accomplish the same thing from the hard disk? That's what I've done with an old Pentium-133 that had a 1.2GB hard disk from back in the day. Just make a standard EtherBoot floppy and "cat" the contents to the hard disk, like so: root at knoppix# cat /dev/fd0 /dev/hda Of course, the floppy drive might be broken, dusty, whatever. Alternately, if you just have the EtherBoot file for your NIC somewhere handy, just do this: root at knoppix# cat eb-5.0.11-3c905b-tpo.lzdsk /dev/hda If you've got to burn a CD to do this (this naturally assumes the old Win98 boxes have CD-ROM drives), then do it. In this case, the "waste" of a CD is well worth it. Note that I used "/dev/hda", not "/dev/hda1" or "/dev/hda2", etc. This is because you're cat'ing to the device directly. You're effectively turning that hard disk into a really big Etherboot "floppy". Then, just boot the client from the hard disk as normal, you'll see EtherBooting taking place, and the LTSP login screen should come up just fine. As for VLAN'ing the clients, I've done that before, for the same reasons that you mentioned; re-wiring just wasn't feasible. VLANs are great for this. Just remember to put the server's internal interface on that same VLAN! :-) --TP _______________________________ Do you GNU!?

The teachers love being able to monitor every screen in the lab without having to stand over there shoulders. They can even lock the I/O or take over and demo for them. That'd be great if it is like that, I brought that up today at my meeting with the other techs. I've been stumped on getting the client to find the TFPT on the server, I made sure all the services were running, and I know the client got an IP. I'm not sure where I went wrong, I started looking through the .conf files, and haven't found anything yet. Last thing, they wanted me to setup one standalone workstation to have nothing but an internet browser. It would be for our lunch room where they will use SIS (student information services) over the internet, and nothing else. You've given me good suggestions on small distributions, but is there a lighter GUI then KDE or Gnome, especially if all I need is Firefox or Konqueror, or can those be run with using a GUI? Can you tell I'm still learning as I go? Thanks again, I wouldn't be getting as far as I am without all this help.

Subject: Re: [K12OSN] Booting older thin clients Be sure, be sure you get TeacherTool (fl_teachertool) completely working before you do your demo; it mostly works out of the box but there are some additional steps you have to do manually to allow the teacher to monitor, control, broadcast to, and spotlight the students' client machines. It's a great WOW! piece for demos that really grabs people's attention. Teachers love it and so do admins. The extra steps for TeacherTool aren't hard, they just can't be done automatically by the installer.

I'm not sure what I'm missing as machines names of the windows boxes can be pinged from linux boxes.to windows boxes and vica versa. The thing Id like to resolve is Ive always just used the default hosts file and the default BIND dns setup. When using Ntop for example..all of the windows boxes shows up as an ip address/or ws001 ws002 and so on. How can I setup the dhcp server(s) to throw out the actual netbios name to Ntop? I have setup the dhcp server(S) with the netbios setting as well as the WINS setting also which are pointing to the winders 2003 domain controller as the dns go getter.. Everything has worked hunky dory other than NTOP just see the windows clients as ws001 ws003 and not Netbios name as id like. BTW: Of course Ntop will show up the netbios names if I static Ip an address into a windows box. Any ideas?

Message-ID: <45E9DB12.3020105@snarlnet.com> Hi Folks, I have some monitors that just don't play nice with k12ltsp. When the client boots and it gets to the "xorg" line, the monitor just switches off. For one monitor adding XSERVER = vesa makes it work. I just bought a cute little 15" monitor yesterday and XSERVER = vesa doesn't even fix it. It seems like its booting normally, then, click, the monitor LED just goes red. The monitor works on an Ubuntu Fat client and the thin client can boot up normally, with the defaults, using a variety of different monitors. I'd love to use this tiny monitor, I'd love to get away from vesa on the other thin client, but I don't know what's wrong here. What causes this phenomenon? What can I do about it?

Also affected FreeBSD, interestingly. By accident, I discovered that if I left it for about 4-5 minutes, I would eventually get the K12LTSP login screen. This was with an S3 Trio64 video board--ordinarily one of my favorite thin client video boards. And no, it didn't affect all monitors that I had, just the OptiQuest. Apparently certain--very few--combinations of monitor and video board just don't get along too well with either K12LTSP or FreeBSD. However, with those combinations, Red Hat Linux in fat-client mode worked just fine. Go figure. My fix--for that particular monitor--was to swap in an ATI 3D Rage Pro video board. The K12LTSP login screen came right up, as expected. And BTW, I'm now using that S3 Trio64 video board with a 19" SHARP LCD screen, and things work perfectly. --TP _______________________________ Do you GNU!?

All that is needed is to write a wrapper script that pops up a box for the student to put in their name, then the app launches and when it closes, the script resumes and grabs the final score and emails it to the teacher. Then have the script dump the high score file so it will refresh each time. Having the ability to actually _do_ things to fulfill needs is why Open Source kicks the proprietary stuff in the teeth most of the time.

If not, no worries. I have a computer that has been running as a dual-boot system for a while. I installed Windows XP and then Fedora Core (it started out at FC1 but has been upgraded and is currently at FC5). They dual boot quite well and all has been good. Recently, however, I found out that the copy of XP I was running was not completely legit (okay, it wasn't even partially legit). I don't particularly like buying from Microsoft but I actually have some things I do under Windows that are needed. I'm a part time photographer and I haven't got my workflow completely working under Linux. Also, I share the computer with my family and the rest of them prefer WinXP. I could have continued with this illegal copy but decided I needed to do the right thing. I bought a copy of Windows XP with SP2. Rather than install this over the existing copy of Windows, I thought I'd put it on a brand new hard drive. That would give me a little time to copy things over, get them installed, etc. and my family could still boot back to the old XP in the meantime. Once everything was working with the new version of XP, I'd clean off the old partition. I disconnected the old OS drive (so I wouldn't overwrite anything by accident) and the installation went fine. Then, I reconnected the old drive and booted to Linux. So far, so good. I added what I thought grub.conf would need but now, I can only boot to Linux or to the old XP partition. Both WinXP (the old version) and FC5 are on the same drive, hda. The second drive, hdb, is a data drive that primarily holds photographs and video and is formatted as NTFS and used by Windows. The new drive with the new, legal copy of WinXP is hdc and it was made into one, single partition (see fdisk results below). I thought all I'd need to do is add a section to grub.conf using (hd2,0) instead of (hd0,0) and I'd be able to boot to either version of Windows but all three WinXP settings in the file (using hd0, hd1, and hd2 -- see below) cause the old version of Windows to load. So, as I said, I know this isn't really a Linux problem and certainly not a K12LTSP problem but if anyone has any suggestions I'd be most grateful.

That will not work as it seems to be in conflict with the boundary markers from hdc1, the _real_ XP partition. You will need to blow away the contents of hdc and partition manually using the linux fdisk tools (it works fine to create an NTFS partition). Then reinstall the new XP system onto the remade hdc1 partition. Your grub.conf entries also are a bit confusing. You have labeled the data directory on hdb the same as the boot dir on hdc. I think the big issue is the existence of hdc4 and it being marked as bootable.

The network systems can handle it but not for more than 1 system. In short, playing a TV set over a thin client network doesn't work. Yes, standalone windows machine can play streaming video. Educate the teachers so the understand that passive entertainment like watching films and movies is done at the full class level in the media center. It is not something to be done on thin client.

Oddly, when I set up the new drive, I only created one partition so I don't know where that hdc4 came from. I thought that if I was going to reinstall everything anyway, it wouldn't hurt to mess with the partition table on hdc so I went in to fdisk and removed the bootable flag on partition 4 and then set it on partition 1. Doubly odd is that now, when I look at the partitions, there is no hdc4. Of course, it still doesn't boot properly to (hd2,0). As for the oddity in my grub.conf, that extra entry for hdb was just to see what would happen. Curious that it would also boot (hd0,0) but I've removed it, anyway.

The problem is that Windows will only boot properly from the first drive. Stupid Windows. Anyway, the authors of grub solved this little stupidity with the map command. It lets you tell the system to treat (in my case) drive hd2 as hd0 and vice versa. Brilliant. This is the full grub.conf entry for my new XP install.

A quick test was done. Make the directory group writeable and set the file mask for that directory to make all files -w- for the group. The teacher can still read and move the files but students can only drop them. They can't copy them or list them. Anything a bunch of kids can dream up, a dedicated bunch of old farts can squash. :) On Sun, 2007-03-04 at 20:59 -0600, Petre Scheie wrote: > It's not as convenient, but perhaps you could give each student her/his > own directory within /home/inbox, with permissions set to 770, and put > the teacher into each student's primary group so the teacher can get to > the files.

One other thing. Originally, you had the new winders drive in the hda position. It _thinks_ it is still hda. (Now I am remembering _why_ I completely dump winders from my systems in 1997 :) You need to edit the boot params for the new winders partition and change it's drive designation. I can't remember the filename other than it's in the top of the drive and it most likely a hidden file. It serves the same function as grub.conf. Basically, it tries to start but the location of the boot kernel is incorrect. I think. I tend to fix winders problems by running fdisk from a Linux CD :) On Sun, 2007-03-04 at 21:40 -0500, Henry Hartley wrote: > James P.

Oddly, when I set up the new drive, I only created one partition so I don't know where that hdc4 came from. I thought that if I was going to reinstall everything anyway, it wouldn't hurt to mess with the partition table on hdc so I went in to fdisk and removed the bootable flag on partition 4 and then set it on partition 1. Doubly odd is that now, when I look at the partitions, there is no hdc4. Of course, it still doesn't boot properly to (hd2,0).

Upgrading the video card is not an option since these are brand new HP T5125 thin clients and I deployed 2200 of them. The process of viewing video clips using thin clients requires that the server do the heavy lifting, not the client. For the same reason than 3D-accelerated graphics won't work in a thin -client setup, neither will using the graphics card to do the video decompression. The servers - all 24 application/boot servers - are dual CPU/dual core Opteron 1.8GHz w/ 8 GB RAM and 6 Gb NICs with 4 bonded for data pipe to the thin clients are all connected with 1000BT networking down to the gig switch in each classroom. The clients are the only thing running slower. > > As for the network "problem" that you outline, that isn't your problem > either unless you're running 100Mbps on your server (you should be > running at least Gig-E on the LTSP server).

The synch between sound and video gets off pretty quick depending on server load, the video is halting and pixilated. I have not been replying much for the past 6 months on this list as I've been a bit busy installing those 220 clients and 24 servers here in Atlanta. > > --TP > _______________________________ > Do you GNU!? > Microsoft Free since 2003--the ultimate antivirus protection! > > > > James P.

BTW my umask is the default 0002 Possible solution? The only thing I can think of would be to write a tiny script (handin) like this cp -p $1 $2 where $1 is the filename, $2 is the dropbox dir, command line args The handin script would have to have perm 2755 (setgid) and have owner root and group teacher. chmod 2775 handin chown root:teacher handin Then set the perm for the dropbox dir /home/inbox to 1730 owned by root with group teacher. chmod 1730 /home/inbox chown root:teacher /home/inbox Then ask students to handin filename /home/inbox Haven't tested this yet, any suggestions? -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From steven at simplycircus.com Mon Mar 5 05:58:19 2007 From: steven at simplycircus.com (Steven Santos) Date: Mon, 5 Mar 2007 00:58:19 -0500 Subject: [K12OSN] Hand-in directory permissions In-Reply-To: Message-ID: I am just thinking out loud here... Couldn't you create your directory and make your handin script (and perhaps make it append the username of the person running the script to the file name?), then instead of setting permissions in that script, run a cron job every x minutes that changes the perms in that folder to root:teacher or teacher:teacher or some such?. You would still be vunerable between script exicutions, but that should be OK. Perhaps this would even be a good first utility for an Fl_student_tool type program? Extend the concept out so that teachers can set up drop boxes in FL_TT, then let students select the drop and turn in the assignment via a student tool type program? _____ Steven Santos Director, Simply Circus, Inc.

After ridding the drive of the NTFS filesystem and replacing it with an ext2 filesystem with "parted", I started backing up the data folders on my new laptop (home directory, photos, music etc.). The throuhput was dismally slow. After some experimentation I discovered that the bottleneck was the KDE "kio_slave" process (my normal desktop is KDE). Below are the results of three quicky "benchmarks": copying the same 170MB ISO file from the system drive to the USB drive. All runs were on the same computer to the same locations. The results of this are interesting: KDE was by far the worst performer, Gnome is much faster, but for pure performance, always go through the regular kernel filesystem. The "kernel I/O" was acheived by mounting the drive the old fashioned way, rather than relying on the desktop managers: mount /dev/sdb1 /mnt/usb Summary: KDE I/O throughput: 1.75Mbytes/sec. Gnome I/O throughput: 17Mbytes/sec. Kernel I/O throughput: 25Mbytes/sec. RAW DATA: ====================================================================== Timings need to include flushing the I/O buffers, so "sync" times are added to copy times for the calculations.

However, it pixelates which is where the teachers start chiming in about the inferior quality. It does get worse as the clips get larger: A 5Mb clip and an 'extended' version of the clip that is 13Mb do not have the same playback characteristics, with the larger and longer clip looking worse. My clients consist of Epia 533-based systems and donated Compaq EN SFF systems. Either can play back without issues as long as they are fat clients. I have Gb from the server to the switch and 100Mb to the clients. If I specify using X11-only, then MPlayer says that the Compaq does not have the resources to play back the video. Using Xv, it does but is pixelated on fast motion scenes. :( MPlayer has alot of options for framedropping, lower fps playback, etc, and I will try and play with these to see if there is some magic combination that provides overall better quality. I really hope that the Atlanta work goes well since it will help me when I periodically try to the the State of Delaware DOE interested in the thin client approach. I have a few Reps and Senators that know about the option, but getting them to commit time to really looking at it has been tough and little glitches like lower quality movie playback seems to 'impress' them more than the phenomenal uptime of the systems, ease of use, ease of management, etc. Slightly off-topic, but the same instuctor that is really vocal about the playback also was vocal about not getting sound on a video clip a few weeks back. After playing it back in a pure Windows environment, it was finally possible to convince him that the clip in question didn't, in fact, have any sound and was only video.

The key was to swap the video board in the thin client for something a bit more powerful. In my case, it was the Matrox Millenium G400; doing that solved all my MPlayer issues. It also, BTW, made TuxType play faster. Heck, I'm able to watch Tom's Hardware videos, in MPEG4, at 720x480, without any framedrops, pixelations, whatever--just nice, smooth video. No, I don't have to throw the -framedrop switch, either. Folks, watching videos on thin clients WORKS FINE. I do it all the time. If you can, please try swapping your video board and see what happens. --TP _______________________________ Do you GNU!? Microsoft Free since 2003 --the ultimate antivirus protection!

I created a script called copy_files_to_dropbox and put it /usr/sbin with a+x permissions. The launcher executes the script passing the filename to the script. Then, neglecting the code for popping up the confirmation window, the script presently is just chmod 755 $1 cp $1 /Dropbox_directory/. The confirmation window simply says the file was copied after testing that the file exists, but I forget the exact syntax. See Eric's push_icons script since that is what I used as the basis for it. There are probably all kinds of reasons to worry permissions on the student's files and such, but in our 5-8 environment, I haven't worried too much about them (yet?). And, I have backups so anything over 24 hours old is archived (via rsync) and then NFS mounted (ro with permissions retained) with another desktop icon (called backups) showing so the user can browse to an old file if needed.

I have 3D accelerated video working just fine on my thin clients. But I've also got a video chipset that is very well supported by X11. This is a big factor; I tried a modern nVidia card in that same thin client, and things got D-A-W-G slow. You're partly right; the client's CPU doesn't do any heavy lifting. But the client's *video board* does in certain cases. > The servers - all 24 application/boot servers - are dual CPU/dual core > Opteron 1.8GHz w/ 8 GB RAM and 6 Gb NICs with 4 bonded for data pipe to > the thin clients are all connected with 1000BT networking down to the > gig switch in each classroom.

In actuality, I have one > with 123 clients and a couple with 110. > My God...are all of these 90 clients/server streaming video simultaneously?? On my dual Athlon 1.2GHz, I show a 640x480 MPEG4 session taking up 21% of one CPU (no frame drops). So, I think I could reasonably get away with 8--maybe 9, but that's pushing it--sessions at that resolution using both of my CPU's. Another MPEG4 clip at 320x240 used up 7% (the HOSEF clip on K12LTSP from last year), so I could do a lot more--maybe 13 per CPU, or 26 total simultaneous--at that resolution. Your network bandwidth does seem to be fine if your bonding four Gig-E NICs; at 45Mbps per session, you can get away with 88 simultaneous streams of that size before the network becomes a bottleneck. That assumes that nothing else is crossing that pipe at the same time, of course (thick clients using the K12LTSP server as a router, etc.). So, for streaming locally from the K12LTSP server, and assuming that there are no errors (faulty cable, dirty connection, etc.), the LTSP LAN looks fine. If you're not streaming locally, i. e. you're doing it from the Internet, then have you made sure that you have a sufficiently large pipe to the Internet for however many sessions that you're streaming at once? We ran into that problem with United Streaming and had to install "cache" servers. Each of our "cache" servers goes and downloads the videos from United Streaming at night, storing them on their (very large) RAID 5 arrays. Then, when our teachers want to play United Streaming videos in class, they get redirected via policy routing to our cache server bank, thus saving our Internet pipe. >> Please stop the FUD and ask questions before you go spouting off >> erroneous conclusions, >> > > Not to sound like I'm biting your head off for the FUD statement, but I > have tested this and found that it simply isn't a workable process to > use thin clients _reliably_ to watch video clips.

We could use some Atlanta common-sense in that way here where I live. But I must re-interate: I've gotten video to work just fine on LTSP clients, and it wasn't that hard.

If you use the normal RH/fedora scheme where every user has a unique group, all you have to do is add the appropriate teacher(s) to each student's group. Then the dropbox directory can be wx by all with the sticky bit set and only the teacher and the student who owns it will have access to the file contents. Or make it real simple and have the script email it. -- Les Mikesell lesmikesell at gmail.com From microman at cmosnetworks.com Mon Mar 5 19:01:32 2007 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Mon, 05 Mar 2007 14:01:32 -0500 Subject: [K12OSN] Pixelation with MPlayer In-Reply-To: References: <1173056935.18688.247.camel@merlin.localnetsolutions.com> <45EB915E.3010509@cmosnetworks.com> <1173070320.18688.280.camel@merlin.localnetsolutions.com> <45EC567D.9070506@cmosnetworks.com> <45EC5912.7040904@maltzen.net> <45EC6661.8040004@cmosnetworks.com> Message-ID: <45EC690C.7010203@cmosnetworks.com> Actually, the full-screen bit is where your video chipset takes over.

If the kids know how to use terminal sessions, then they could also just share files directly from each others accounts though and bypass of this unless you lock the top level accounts so that they can't change their own directories permissions. Not sure how to do that. Now, once the file is dropped, the directory permissions don't allow them to list the dropbox directory contents. The files get the permissions specified, but the directory is set so that they can't see the contents. 'course now I need to go back and re-evaluate how I did this. The tech teacher wasn't too concerned about possible issues since if cheating occurs, there are ways to address such issues and use it as another opportunity to teach values. I also have a cron job that runs every 5 minutes to change the permissions just in case as well. As for manually running scripts, the tech teacher doesn't want to deal with anything that has syntax. Double-click, drag-drop, right-click are all good. Opening a terminal session and running a command is not on the list of good things. Long term (next year), I will find a better solution but right now this works well enough.

This new version includes two additions blatantly copped from Knoppix: -At the end of the boot process, Firefox is launched with a "Welcome" document on the CD that explains what it is, etc. -If you put the disk into the CD drive of a running Windows system, it launches the web browser with a document similar to the "Welcome" document mentioned above, but which also includes a section on how to use it (reboot the machine with the CD in the CDROM drive). If you don't want these additions, the original version (0.1) is still there, too.

They are Epia533 but they have the PLE133 video chipset. This is a real downer for me since I don't see where this chipset (which uses the trident video driver) has any support for MPEG acceleration (or whatever it is called). Apparently later versions have the CLE266 (Unichrome) chipset which does but you have to be careful since they are still selling ones with the PLE133. We have had these clients since Spring 2003 and they run flawlessly (even ordered another 30 Spring 2005), but ... I am now not sure if they can handle video streams well enough. I guess I will be spending time looking for more recent drivers, maybe a BIOS update or somesuch adds better support for video. Or, see if they support an add-in video card and purchase them but we have 75 of them at this point and that could run ~2K. If anyone knows how to get a better driver, please let me know. I can't even determine where the trident driver is loaded from: best guess is it is bundled with the Xorg software? There is a tridentfb.ko, but I wasn't able to get it to load. Hopefully, tomorrow will be better. :) Sincerely, Dave Hopkins On 3/5/07, "Terrell Prud?

In fact Dean from http://groups.google.ca/group/bcfosss gave me a similar solution. Here is his idea: Ok how about : chown :teachers /home/inbox chmod 3773 /home/inbox This will ensure that group is always teachers for all files in that folder...

Also, shouldn't your chmod be 750 since you don't want others to be able to read and thus copy it out of Dropbox_directory? And what about /temp where everyone has read/write access? The reason I am being so anal about the security is because I give my classes programming tests and I don't want them being able to copy anothers solution. After having a chat with a friend about this, I think the best solution may be to simply ask the kids to save their solution as their username.py in their own home dir.

Tried resetting the desktop, but this is only happening for one user (currently). Just strange.

After the line DEST="`basename \"$FILE\"`" the rm commands should point to $DEST, which is the filename with the path stripped away. However, the rm commands still reference $FILE, which is something like /root/Desktop/Icon.desktop, where Icon is the name you gave to the icon. But since $FILE still contains the full path, in this case relative to root's home directory, the rm commands won't work because they'll try to delete /root/Desktop/Icon.desktop from each users ~/Desktop directory. Changing the rm commands to use $DEST instead of $FILE fixes this.

However, alot of District IT departments seem to have the attitude that you have to pay for the best product (at least here in Delaware). So ... if the cost of getting the best is a service contract, they don't blink. Still, with voters turning down referendum after referendum on school tax increases, maybe they will change their attitudes. Sincerely, Dave Hopkins On 3/6/07, "Terrell Prud?

Most adults are afraid of their computers, are afraid they'll stop working, are insecure about their ability to use them effectively, etc. If you can understand those anxieties, then you can provide answers to solve those problems so that people like the principal become advocates not just bystanders (in theory, anyway).

You only need enough CPU oomph to transfer and display metadata--screen updates, keystrokes, mouse movements, and, if you've turned on sound support, the LTSP sound daemon. For that, you really only need the processing power of an 80386. Yes, an 80*3*86. I regularly use old Pentium-166's with 32MB DRAM in them, with no "flash memory" at all, and they work great. But there *are* a couple of things that *do* matter: 1.) the video chipset, and 2.) if it supports either PXE-booting or EtherBooting. The video chipset is rather important. We just had a discussion in another thread about thin clients that, unfortunately, seem to have a pretty sad video chipset in them (an old Trident type). This is, we believe, causing some issues with video playback, especially in full-screen mode. I've got a Pentium II-300 and a Pentium-166, both with Matrox Millenium G400 video cards in them, and video playback works very nicely. If you can get "fan-less" thin clients, that is, thin clients that use just a mondo heatsink with no fan, then so much the better. It's quieter, and there's one less part to break down the line. Not by any means critical, but it is nice. --TP _______________________________ Do you GNU!?

Yes. Even more important is the video card. Looking at the spec sheet here: http://www.thinstore.net/hpt5125spec.cfm I am not sure about the video. 16Mb would seem to be enough, but it says nothing about 2D/3D acceleration, MPEG acceleration in hardware, etc. I am very gun-shy right now because I haven't resolved my Epia issue (with the Trident/PLE133 graphics), but these are based on an even slower cpu than what I have (mine are 533Mhx Epia 5000 and Epia V). Others will hopefully mention disklessworkstations http://www.disklessworkstations.com/cgi-bin/web/info/ltsp_t150.html?id=yd4tS8GU which are very similar to mine, so a resolution to the video issue should exist for them.

The reason I am being so anal about the security is because I give my classes programming tests and I don't want them being able to copy anothers solution. After having a chat with a friend about this, I think the best solution may be to simply ask the kids to save their solution as their username.py in their own home dir.

I have just installed a test k12ltsp on a virtual test server. I am using etherboot on dhcp port 1067 on my clients. I am able to authenticate to my windows 2003 active directory. I am using the gnome desktop because It is fairly easy to attach to users folders residing on my Windows 2003 file server. In looking at the processes, it says my client is using around 150 megs according to the Teaching tool. I am thinking of trying to introduce these clients to be simple word processor/internet machines for the English rooms. Most are just using the ancient fat client windows machines currently in these rooms to type essays and maybe to do a little research on the net. I have no need for sound on these. Is there a way to reduce the amount of resources the client is using.? How do you disable some of the unnecessary applets in gnome like bluetooth or things related to audio? Any suggestions would be really appreciated. I am totally new with linux, so you might have to write really slow for me to understand. :) I have been on the mailing list for only a short time, but it looks like there are alot of knowledgeable folks out there. thanks so much!!

So I am hunting for a language that I can teach to a teacher who can teach it to students. If the students are taking well to python... there could be a gleam of hope that teachers could learn it too :-D Is anybody teaching klogo-turtle to their elementary students or know about someone who is?

We are lucky enough to have 1:1 laptops in our high school (came with windoze for the grant, but the grant is over, so I am going to have my way with them next year). The problem is that the only thing they are used for is M$ office! Is anybody having any success getting students involved and interested in technology past the basic M$ office classes (other than what we have already discussed)? The reason I am asking all this is so that I can gather some good examples of how people are making students excited about tech using free software (stuff that windows can't do is always good) so that they will have an easier time with the onset of my impending GNU/Linux takeover.

Then about 2/3 of the way through the junior course I introduce (import os and sys) So they can start making system calls and use command line args from within a python script. Very fun! In my senior course I get into object oriented programming and gui's. In the past I tried teaching FLTK in C++ but found there was too much C++ overhead to teach high school kids. So next year I am planning to teach pyFLTK. pyFLTK is basically the same as FLTK but in python and without the overhead of pointers, dynamic memory allocation and destructors. Look at this simple object oriented pyFLTK program. It shows how widgets can talk to each other. #!/usr/bin/python from fltk import * class MyApp(Fl_Window): def __init__(self, w, h, label): Fl_Window.__init__(self, w, h, label) self.begin() self.button1 = Fl_Button(95, 5, 140, 50) self.button1.label("Not clicked yet") self.button1.callback(self.button1callback) self.button1.color(FL_BLUE) self.input1 = Fl_Input(95, 90, 140, 50) self.input1.label("Input box") self.end() def button1callback(self, widget): widget.label(self.input1.value()) Fl.scheme("plastic") app = MyApp(450, 155, "Widget communication") app.show() Fl.run() -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn For more info see -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Now I would like have more power with little money - more scrap clients and 1-2 more old servers. Btw, servers are 1000MHz double PIII servers with some 1,5G memory each. Each have scsi raid1 system disk and one has 300GB raid5, where I could put also the /home folder. So, I would like to set up a dhcp load balancing system or just put the servers each in separate subnets. Either way, I would like stay in 2 ethernet card setup. So, - is the loadbalancing possible with 2 ethernet cards? Is it possible to put more than two servers in this setup? - if just using shared NFS /home on one of the servers, is there anything I should consider when following the instruction s on K12LTSP server configuration webpage?

Run "top" and take a look at the RES and SHR columns. Fl_Teachertool reports the total of RES but it does not subtract shared memory SHR. If 30 kids are running firefox and each RES is 50M with each SHR 15M then the actual consumed memory is 30x(50-15)+15 = 1065M not 1500M At least that's my understanding. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From dyoung at mesd.k12.or.us Tue Mar 6 21:15:48 2007 From: dyoung at mesd.k12.or.us (Dan Young) Date: Tue, 06 Mar 2007 13:15:48 -0800 Subject: [K12OSN] newb question In-Reply-To: References: Message-ID: <45EDDA04.5010302@mesd.k12.or.us> Pete Horm wrote: > HI Everyone, > My name is Pete.

They use Java and are equivalent to either the first or first and second semesters of a typical college CS major. I would highly recommend teaching an intro class before offering AP, though, as the curriculum and test are pretty challenging. In my school, we teach three years of programming. We begin with the How To Design Programs curriculum (http://www.htdp.org) developed by the TeachScheme! project (http://www.teach-scheme.org). The textbook and all the software you need for that is freely available online. It's what I use for my of the first year. At the end of the year, we transition to Python. It has less overhead than Java, but has similar syntax. The second year is the AP course, using Java and the BlueJ programming environment (http://www.bluej.org). For students who've survived the two previous classes, we offer a Special Topics in CS class. The curriculum varies, but this year we're doing Python and creating web applications. I highly recommend the HtDP program. It's pretty student-friendly and has a really active group of high school and college teachers who use it.

Did you find the curriculum or develop it yourself? Is this most of your students' first exposure to programming or are they introduced to it in lower grades with kturtle or something similar?

For load balancing your servers,you can simply enable dhcp on all servers. I know it sounds not logical,but this is how Ive run our K12LTSP servers, on two school subnets for 5 years. I was going to try and setup the server cluster thing in Webmin but this has worked fine for us. If you power on 20 computers,,for example at the same time,,you will simply get a login screen to the " least busiest server", at the time. If you wanted to get real "down to the brass tacks",, you can setup each server to serve dhcp to certain clients( by mac address) and just divide clients by number of servers, This would be a lot of extra entering,and you really wouldnt gain anything IMHO. No need to make things more complex than they need to be:). You can either setup, your users on an " authentication server",and point each server to this server,or its easy as well to use Webmin to add all users,to one server ,then export them to all other servers on your lan.If you have older hardware this would be a good setup. If one servers dies,,,you keep on rolling without having to add/setup a new authentication server:) Either way will work,without incident.

Sure. Do not define range and make individual listing for each MAC address in your dhcpd.conf file...something like: host ws166 { hardware ethernet 00:c0:26:a1:17:71; fixed-address 192.168.0.166; filename "/lts/vmlinuz.ltsp"; } -- Regards, Sudev Barar From microman at cmosnetworks.com Wed Mar 7 06:05:45 2007 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Wed, 07 Mar 2007 01:05:45 -0500 Subject: [K12OSN] newbie: nfs /home and load balancing issues In-Reply-To: <55979.80.186.188.166.1173208762.squirrel@webmail.edu.vantaa.fi> References: <55979.80.186.188.166.1173208762.squirrel@webmail.edu.vantaa.fi> Message-ID: <45EE5639.70009@cmosnetworks.com> It depends on your load. If you've got a bunch of clients wanting to do streaming video, then those PIII 1GHz chips might not be enough. If, on the other hand, you're just doing OpenOffice.org and Firefox, you should be fine with simply adding more DRAM to your servers. That'll let you add more clients per server. If you can make them 4GB, do so. In the past, I had a dual-Athlon 1.4GHz box with 4GB DRAM and EIDE disks serving about 25 clients, and it was suh-weet. Scrap clients are so easy to get cheaply. Corporations are *dying* to get rid of older PC's. I personally favor the Dell OptiPlex GX1's, since they are dirt-cheap (companies will very often give them away to avoid disposal fees), support PXE-booting (some may need a flash update--very easy to do), and all the hardware works great with Linux. Highly recommended. If you can't find any OptiPlex GX1's, then another excellent choice is the HP Vectra VL400 series; it, too, supports PXE-booting very nicely. --TP _______________________________ Do you GNU!?

Deep Freeze realized that he did not hold a valid license to the product and would not offer him support. This upset the person and in turn wrote a script to corrupt the program, Faronics wrote a patch, he wrote another script, Faronics wrote another patch, this went on for a while but has not been a problem for a year and a half now, a few versions ago at this point. Anyway, I thought you might be interested in this current information. Also, I am happy, for the most part, with the network we have in place now, It does have it's good points along with it's bad, just like any "other" network system. Thank You.

The system has been running fine for almost 3 years now so I'm not sure why it has suddenly started doing this, I've not installed any new software or run any updates since it was installed, I know this is bad but it's a Fedora Core 3 box and with the closure of the fedora legecy project it's not that simple to do updates. This is our main Samba server so I'm a little concerned about just trying things as the system also runs our OpenLDAP server so is the "heart of the machine" Any pointers would be gratefully be received.

It's pretty rare that a user-space program can cause a kernel panic, unless it's managed to trip over a bug in the kernel. I'd say it's more likely a hardware issue. First thing I'd do is shut down the machine, open it up, and re-seat all of the cards and memory. Make sure everything is plugged in securely.

I've used the Xv MPlayer output driver with ATI cards, and things worked fine, even with accursed .WMV's. Could you try out another video, say, one in MPEG4 format? That's supported directly by ffmpeg (no Windows codecs needed), so this'll help us determine if you might have a codec issue. Also, if you can get your hands on an Ogg Theora video (here's one: http://mediacast.sun.com/share/tmarble/moglen.ogg -- about 2.3MB) and try that. --TP _______________________________ Do you GNU!?

Windows share security is done per share. Remember that each box has its own database of share security that needs tweaking. Another way to manage permissions, which might make this sort of thing easier, it is to have all the staff members' files on a central file server. At work, we use a "H" drive ("H" is for "home"). Then, you can manage file permissions centrally w/o having to touch the client boxes. Works out rather well for us. You could use a Samba server for this very easily. --TP -------------- next part -------------- An HTML attachment was scrubbed...

That way you don't have to mess with the Windows machines. Anyone who's good with iptables wanna take a crack at creating such a blocking rule? I'll make what is probably an incorrect attempt to start the discussion: iptables -A INPUT -p tcp --dport 137 -j DROP Add similar rules for ports 138 & 139 (there's a way to specify a range, but I can't recall the syntax) and your linux box won't be able to 'see' any Windows shares.

I have to agree....and not because I'm a Linux zealot, but because I'm a realist and also a businessman. The fact that Vista isn't flying off the shelves is a large indication that we've reached a crossroads. This may be the point at where other OS's begin to encroach on MS's marketshare. It may be a slow process, but it could be the beginning of a long backslide. I've talked to many MS engineers and developers....even they admit that the code is silly, bloated, and poorly written. Granted, there are many cool things about Windows, but in the end, the quality of the code may be their undoing. More eyes are able to watch Linux and even Mac code and thus keep it clean and less buggy. Linux is on the verge of a breakthrough. There are many features that will be arriving in new distributions this year. For example: the Aero features in Vista....are already part of Linux and will become more mainstream and included by default in many distributions. Ubuntu and Fedora will probably release "authentication server" distros that will integrate with AD as well as Samba/LDAP making it a cinch to drop in a linux server either in place of or alongside a Windows server...and it will have the GUI interface we've all come to love. Nowadays many Linux installations are easier than Windows....just answer a few questions in the beginning and voila! Ubuntu will release version 7.04 (Fiesty Fawn) in April which will have many of these features, or will have laid the groundwork for most of them for the following release (7.10 no codename yet) in October. Windows comes out with a new release once every 2 - 8 years.....many Linux distros do so every 6 months! I suspect that Fedora and Novell/SUSE also have some tricks up their sleeves for this year. Apple also has Leopard waiting in the wings....it promises to be pretty cool. Apple has been coming on strong and slowly chipping away....Leopard could make up some folks minds about whether to buy a new PC with Vista or a new Mac with Leopard. I also suspect that new iPods and iPhones may also help drive some of those decisions given the timing. MS was embarrassed by the constant set-backs in cooming out with Vista. (It was supposed to be here a couple years ago) Vista is lacking many of the features (namely the WinFS filesystem) that MS promised. Unfortunately, I don't think MS can afford this "weak" showing. I'm not saying MS will go away, but I think you'll find that MS may become just another player in the market after a few years as the alternatives gain marketshare. This could indeed be the beginning of the end. I used to be one of the first to run out and upgrade when MS came out with a new OS....I haven't even loaded Vista (and I have a copy!) or Office 2007 (I have that too!)....I just don't see the feature set or the cool new toys that would make me want to do so. On the other hand....I can't wait for Leopard....and will install Fiesty Fawn probably before it's properly released. Yes....I agree, Ed....this will be very interesting to watch.

Also, you want to make sure you're specifying the interface. In this specific case, it might not make much effective difference, but that's bitten me in the butt before when I haven't done so, so I always do it. There's another important question here: does he want to stop *all* NetBIOS traffic to *all* Windows machines everywhere, or does he want to permit it to certain servers? Here are the specific ports that you'd need to deal with. And for those who are kinda new to packet filtering, know that *UDP vs. TCP MATTERS!!* UDP 137 UDP 138 TCP 139 TCP 445 (this is the new Craptive Directory NetBIOS introduced with Windows 2000) Say you want to allow NetBIOS traffic in on eth1, your external interface. However, you want to allow NetBIOS traffic to a Windows server with IP address 10.0.0.10 (say the main school LAN is 10.0.0.0/24). Here's the ruleset that I would try adding to the beginning of any ruleset that you already have: # First, allow traffic from the server that we want. iptables -A INPUT -i eth1 -p udp --source 10.0.0.10/32 --source-port 137 -j ACCEPT iptables -A INPUT -i eth1 -p udp --source 10.0.0.10/32 --source-port 138 -j ACCEPT iptables -A INPUT -i eth1 -p tcp --source 10.0.0.10/32 --source-port 139 -j ACCEPT iptables -A INPUT -i eth1 -p tcp --source 10.0.0.10/32 --source-port 445 -j ACCEPT # #Now, block all other NetBIOS traffic iptables -A INPUT -i eth1 -p udp --source-port 137 -j DROP iptables -A INPUT -i eth1 -p udp --source-port 138 -j DROP iptables -A INPUT -i eth1 -p tcp --source-port 139 -j DROP iptables -A INPUT -i eth1 -p tcp --source-port 445 -j DROP If you don't have any ruleset, there'll be a default-deny, so you'll get to include a "permit whatever else" statement to your liking at the end of your ruleset. I might do something like this, for "permit everything else in the world": iptables -A INPUT -i eth1 -p tcp -j ACCEPT iptables -A INPUT -i eth1 -p udp -j ACCEPT iptables -A INPUT -i eth1 -p icmp -j ACCEPT Comments? --TP Peter Scheie wrote: > I haven't done this, but considering Windows shares use port 137-139, > I'm pretty sure you could add a few rules to iptables to block > outbound traffic destined for those ports.

Message-ID: <20070308000703.M47011@winonacotter.org> Has anyone looked at the possibility of using something like a Dell 1955 Blade Server as an LTSP server farm? I am looking at trying to deploy 100 or so terminals to start moving to 500 or so in the next couple years in a single location. I am wondering if using a blade server like this (holds 10 blades) if I could set up the first blade as my LDAP server, Second blade as my email server, 3rd blade as my ltsp server, then hang my Dell PowerVault off of the blade chassis and mount it as /home on all 3 blades. Then later when I need more LTSP horsepower I could buy another blade and round robin it, later maybe more. If I need more power for OpenOffice or Firefox I could add another blade to be an application server, or more. Does anyone know if this is possible? I see they have many Ethernet ports on the back and a built in Cisco switch for network connections. Could these blades talk to each other internally and not even have to access the network making for an extremely high speed backbone for communication between blades? Please let me know with any thoughts or suggestions. I sure would hate to invest $10,000 in hardware to figure out it wouldn't work. If it is possible this could make one kickass server setup in one package.

Message-ID: All, The Tech Coord installed a new printer yesterday. Printing to it works if using the cups web interface. But ... not a single application on the system can now print to anything. e.g. Firefox and Staroffice both only show generic printer. lpstat -a hangs and returns nothing. On the other k12ltsp server, lpstat -a returns a list of all printers installed for the school, including the printers on the misbehaving system, so cups is working. So ... any ideas what has broken? I would guess it is some authentication/privelege issue on a file/directory that lp wants to use, but which one? When the tech coord installed the printer, he said that Toshiba instructed him to 'just launch the self-extracting archive' for the printer that was delivered. I have no idea what this did since my normal way of installing a new printer is to just get the ppd file and use it. Additional info: Printing to printers attached to this system work if printing from any other system, so the cups interface seems to be working properly. ????

A little while back, I wrote a paper for a graduate class I was taking in network security. I didn't get asked if I was Ghostbusting, but I did get a number of strange looks with my setup. You can find a copy of the paper at: http://www.keokukhigh.net/~ericbrow/wardriving.pdf I'm not sure what you mean by Windows being dangerous. Netstumbler is just a program that works at the application layer. If you're meaning that with your equipment it produced dangerous waves, I would think it's more the extra equipment than the program. While I'm no fan of Windows, I'm just as disgusted with OS X at this time. Our school's wireless network is mostly open because those in charge can't get WEP to work. Furthermore, we're forced to use 10-base hubs because the Macs flip out when hooked to a 100/1000 base switch (tested with switches from multiple manufacturers). I'd still use XP over OS X, but I'd prefer FOSS over all. As a country, we may end up with an accidential wireless mesh network yet. Eric On 3/8/07, "Terrell Prud?

For example, a key area of contention is audio. We used to have audio with the lab, but then one day (I THINK it may have been after a yum update) it just stopped working and I am totally unable to get it to work again. Another aspect is name recognition. Windows XP has branding power. Parents know it. Principal knows it. Teachers know it. No one has heard of Linux. So why are we using an operating system that no one has heard of? Same for Microsoft Office vs. Open Office. If you cite the cost reason, it just creates a sentiment of inferiority. Oh - we have to use Linux because we can't afford something better. IE: I need to drive a old, beat-up used car because I can't afford a new, name-brand car. Instead of exploring the possibilities that Linux provides, the people just see the lab as sort of a holding pattern -- we're here until we can get something better. Hence why I get comments like "Hopefully in the future it can be Windows", mirroring "hopefully in the future I can get a better car". That seems to be the situation here. Thoughts?

I would have to respectfully disagree on the belief that people haven't heard about Linux. There has been alot of information about Linux. I can assure you that the kids have heard about it. The sound issue should be easily fixed with some troubleshooting and help from the experts on this forum. I completely agree with the comment on the product being free therefore inferior. I hate pushing opensource or Linux as the "FREE" solution. I like to take the approach of better performance, security, and reliability. I know that keeping a lab up and running no matter what OS is being used is VERY important. People don't tend to notice what you are using until problems start to arise. At that point, it becomes very easy to just blame the OS, whether MS or Linux. I would make sure that you are running the latest and greatest and then show off tools like Teacher_Tool to demonstrate the benefits of K12LTSP. Just my 1 1/2 cent, Ron Ronald R.

So many are ignorant of it. My point on Netstumbler was that it is not a passive program, it transmits. That antenna has 24 db of gain (effective radiated power doubles every three 3db, so that's a lot of doubling) and that is not a healthy level with your head right next to it. By the same token, you shouldn't try to even connect to an AP like that, because that is still transmitting. I spoke with the distributer (Fab-Corp) of that antenna, and they said a safe distance to be while it's transmitting is five feet. Five feet BEHIND it, there are side lobes that are larger. Netstumbler works by sending probes en masse on every channel, and looking to see what responds. It's like walking down the street with a bullhorn yelling MARCO and then listening to see who replies POLO. Technically it is not connecting to the AP, but it is not by any means quiet about it. It is logged, but of course Joe Average doesn't know about that. It is really less intrusive than the default XP behaviour of connecting to whatever it can find. Kismet is completely passive, no transmitting. It will also find those "SSID Hidden" ones. It's quiet and safe. Kismet also has options that I don't believe Netstumbler has to log a dump of the data received. In playing with this, I can drive by a college dorm, and capture snippets of email, web pages, MP3's and so forth that are going by in the traffic. After a few times of playing with it, I keep it defaulted to off on data dump. In USA it is legal to watch/look at anything non-encrypted on wi-fi. In some jurisdictions it can be considered an illegal wiretap to store it, so I don't. I am an active wardriver, http://wigle.net has a DB of 9 million AP's. Of 62,000 people signed up in the world, I currently rank #56. I don't pursue it that hard, I just keep doing it. The Big Guys get more every month than I've gotten in five years. I am in no danger of making the top 10. I do it casually, once a month or so (or whenever I travel). The guys that are over the road or pizza delivery guys get the most.

Robert, One of the primary reasons I use NX instead of VNC on my LAN is because it's got an "available area" setting for the display size. I don't know how it's done, but it's much more convenient than picking a size w/ VNC and toggling back and forth between full-screen and window. I wonder if you could apply the same tricks to teacher tool in order to provide the feature these guys are requesting. -Rob From rowens at ptd.net Thu Mar 8 22:27:13 2007 From: rowens at ptd.net (Rob Owens) Date: Thu, 8 Mar 2007 17:27:13 -0500 Subject: [K12OSN] Terminals Rebelling!

This will be for a completely new setup. I am stuck between Edubuntu Feisty and K12LTSP6. I have been testing both. I really like the ease of upgrade Edubuntu offers and the large debian repository, but K12LTSP still seems faster and packaged better....decisions, decisions. If you could email me module and your lts.conf lines that would be great. I hope to make a purchase within the next couple months. Looking at a new LDAP server with 2 LTSP servers to start and a separate file server with an attached PowerVault. Then depending on performance I might hand some application specific servers off the whole thing. I want to start with about 100 clients and ramp up to about 200 within the next year. So I need to plan this out right from the beginning and be sure I have a plan in place that can grow.

Here is my solution: 1.) Rename /usr/bin/tuxtype2 (the executable) to, say, "/usr/bin/tuxtype2-bin". 2.) Write a very small shell script named /usr/bin/tuxtype2 that calls the renamed executable in window mode. Kinda like this: #!/bin/bash /usr/bin/tuxtype2-bin --window And then, "chmod 755 /usr/bin/tuxtype2". Works like a charm. Just tried it with ChildsPlay, too, with several games, and it works there, too. --TP -------------- next part -------------- An HTML attachment was scrubbed...

There was a problem with the mknbi package on Dapper, that's why dapper's version of ltsp didn't easily support etherboot clients. We resolved that last fall, and the fixed version made it into edgy.

This is not something I can do easily, since you have the NX client running on a seperate machine. With ltsp it's easy because I don't need any authentication to take over the remote client machine (I am already root on the ltsp server or sudo). So with NX I would need to make a new version that employs ssh keys and that opens up a whole new bag of worms. Again if anyone wants to take on this task to make a new version for NX or LDM (LTSP 5) I would be willing to help exlpain my C++ code and help code as much as I can.

No complaints at all, Unbox it, go into bios, enable PXE boot, if you so desire setup its own ws00x in lts.conf and use the specified video driver( it works fine with the vesa driver too),, you'll have to compile the sound module on K12LTSP for audio to work, ,and it works. its that simple I can have 10 web browsers open with no probs. Java Apps dont drain it either.As was mentioned here full screen Tuxtype/Tuxmath does NOT work but windowed works fine. Nice thing is 0 noise!!! and almost 0 heat .Mounted on back of an 19" LCD monitor. I cant seem to see any to nasay about it honestly. $120 plus shipping from Bangkok . There is an US reseller now,,I think? Very cool. For the price and the speeds I think I'll trade not being able to do full screen for some apps. I am looking at buying around 100 machines for 4 of our labs very soon and this looks very promising. Thanks, Jim We use a lot of LCD monitors in my district, very few (if any) of which support TuxType, TuxMath, or ChildsPlay in full-screen mode. Here is my solution: 1.) Rename /usr/bin/tuxtype2 (the executable) to, say, "/usr/bin/tuxtype2-bin". 2.) Write a very small shell script named /usr/bin/tuxtype2 that calls the renamed executable in window mode. Kinda like this: #!/bin/bash /usr/bin/tuxtype2-bin --window And then, "chmod 755 /usr/bin/tuxtype2". Works like a charm. Just tried it with ChildsPlay, too, with several games, and it works there, too. --TP -------------- next part -------------- A non-text attachment was scrubbed...

If it's on the thin client, it sounds like a video driver issue. I've seen that come up when using newer nVidia or ATI cards, now that they don't like to provide programming specs anymore (ATI used to, up to and including the Radeon 8500). Try tossing a Radeon 7500/8500 or Millenium G400 in your client and see if you get better performance. That worked for me. Also, see if you can give something with integrated Intel video a shot; Intel made their video drivers Free Software last year. They're not speed demons, but they do work in 3D. _______________________________ Do you GNU!?

Message-ID: <58950.192.168.254.3.1173551409.squirrel@www.eazylivin.net> Joe, Have you tried changing the IP address to another available term server ? What term server are you trying to connect to? 2003. if so what service pack is it using, although it should not make any diff.? I just dumped SP2 onto our 2003 servers a couple weeks ago and clients still can SCREEN_01= rdesktop to them, FYI. Another thing to try on this particular client. Boot into K12LTSP. then in a terminal do " telnet termserveripaddress 3389 " . If you get a response this way there is no reason the client should not connect to this termserver unless the licensing reg keys are wonky.

Sudev, I yanked this out of google http://www.verifiedcomputers.com/itemDetails.cfm?itemID=2000425 This would represent the best of the batch of what we have to offer but most are 350 MHz. If you want actual pictures I will take some and post them on our website next week These are nice little boxes. Some of the HDs have a noisy whirrr to them. they lived their first 3 years in our school with the HDs unplugged so it was not a factor. it was a sad day when I had to plug them back in and load W2K BUT I did make them dual boot K12LTSP and ya know what most of the students choose? K12 Linux! Many of these are in use right now in some of the classrooms and look real good with LCDs sitting on them. If power in the classrooms was not a factor I'd keep em and up the ratio of PCs to students. Since posting this here I have had some emails off list. I will sell them onesy twosy if I have to but would love to sell the whole lot of them or blocks of 25.

Most modern e-mail clients and webmail (gmail for example) will colapse the 'cruft'. Further, when I come apon a discussion that I found through searching the web.. I'd much rather hage the entire conversation there, rather then have to find the start of the thread and then keep clicking through it to read it. It's much easier to just go to the bottom and read back through the entire dialog.

I notice on one of my K12 ver. 6 installations that yum does not update fl_teachertool to the latest version (0.41). Rather, version 0.41 is available at http://k12linux.mesd.k12.or.us/K12LTSP/testing/RPMS/. I downloaded the 0.41 rpm and installed it on a test system and it seems to work fine. Can/should 0.41 be moved over to the regular repos so yum can find it?

The very most important thing to me is, to make it as easy as possible for someone to offer their support on this (or any) list. For me, sometimes i've got a quick answer, and I'll just post it at the top. Sometimes, the person asking the question does so in a way that is formatted like a list of questions. In those cases, it makes great sense for me to try and answer each question individually, so that's what I'll do. But above all, if someone wants to take a few seconds of their time to try and help somebody, the last thing I'll do is criticize how they post (top/bottom/inline). I'm MUCH more interested in the answer, than how it is presented. If I were a LTRFTP (Long time reader, first time poster), and I posted a reply, and then had somebody tell me my method of replying was wrong, that'd be the last post I ever made to that list. And now, i'll shut up, cuz I can't stand getting involved in discussions like this. They do nothing to help people use the software that we're so busy trying to provide.

What is missing is that I did not really wanted to start top line inline bottom posting discussion BUT to tell people to avoid html formatting.

I've had the same experience, where clients that worked perfectly with version 3.x wouldn't work (at first) with version 4.x, and likewise with version 5. To fix it usually involves setting a specific X server for that client in lts.conf. Often, it's the vesa X server that works. So, in lts.conf, try changing XSERVER = auto to XSERVER = vesa or since you have Intel video chips, you might try XSERVER = i810 LTSP defaults to 1024x768, but you can specify the resolution if you want, and this may be necessary to get the res you want.

No, but I did contact Dell. From my gathering if someone wants to build the ultimate LTSP cluster, these are the ticket. However not cost effective unless you populate the chassis with at least 7 blades (takes a while to cover the cost of the chassis, and they'll hold 10 blades). But each blade can function as it's own server (up to 10 blades per chassis) and each blade can handle up to 2 Quad Core Intel Xeon 5355's (2x4 MB Cache, 2.66GHz, 1333MHz FSB), 16GB RAM, and 2 SATA or SAS hard drives. Each blade is able to talk to all other blades via the chassis backplane (alternative to a management LAN). Also if you have a fiber channel storage device it is able to plug directly into the back of the chassis and be able to be used by all blades locally (no need to share /home from a RAID array via NFS, just mount locally). Also they accept managed switch modules which are totally configurable. You can assign ports to specific VLAN's, team multiple ports to specific blades, or just assign a single port to each blade. So I could actually make blade 1 my LDAP, blade 2 my LTSP boot server, blades 3-5 application servers, blade 6 my mail server, then attach an external fiber RAID array and mount as /home to all servers that would need it. LDAP auth would happen internally across the backplane. I could consolidate my whole head end into a single 7U chassis, very cool. And since /home, LDAP and application serving would only happen at the backplane level I am sure it would alleviate network congestion and speed things up. But I have a handful of servers and a PowerVault 220s already, not sure I can justify the cost. But it sure would be my choice at this point for a completely new setup. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

It is /home/SCHOOL. 2 Questions. 1. Is there a way to alter the push icons to desktop script to push icons to the users listed in the /home/SCHOOL folder? 2. Is there a way to standardize a gnome desktop for these active directory users? I tried a couple of different things that were suggested (/etc/skel) , but they don't seem to work. I can take the programs out of the /usr/share/applications. The reason I am using gnome is that it can easily attach to their windows network folders. I need to keep it easy for the students, so that I can convince my administrators to give K12ltsp a try.

The pictures are then view through a web browser as a thumbnail of each computer. The Webpage refreshes itself every few seconds which updates the screenshots. The pictures are linked to a page with the full size picture. Clicking on this launches the java web based vnc viewer on the machine being viewed and the teacher can then control the pc or just view it live. This all seems to work OK. One improvement I would like but don't know how to do is to have the script recognize a failed snapshot (like when the computer is switched off) and use a different standard image. Then it could be clear at a glance that not all the PC's are on. This is significant as when a PC is off it takes a lot longer attempting to capture that screen. If several are off this adds a significant time lag before the images a re all re-captured. It's not a major problem but it would be nice. Having it web based is very elegant as it works well on both windows and Linux clients even on LTSP as the refresh rate is only every few seconds.

The real question is, since /home/SCHOOL is actually a Windows directory, whether or not root has write permissions to each user's directory with /home/SCHOOL/; my guess is no, but I could be mistaken. In case I'm wrong, and root does have the necessary permissions, look at about line 40 in push-icons-to-users-desktops for the area to change to have it work through /home/SCHOOL rather than /home. > 2.

Do you mean customize a gnome desktop and then make that the default for all users? If so, check out sabayon.

The only time I have seen a difference is when my file server also is hosting email and large transfers are happening (sometimes can bring webmail to a halt). Also I use heavy screening for SPAM and Viruses, sometimes MailScanner alone can put 30% load on the server. Main reason I want to break things down is I am sick of playing games when doing upgrades. Say I have one server running LDAP, file serving, mail, web, etc I have many more factors to weigh when doing upgrades. That is the only reason I am looking at breaking things down more. Most likely the final result will be to have my LDAP and email on the same server. But I like the idea of having a stand alone box that just handles user authentication. The blade for the LDAP server could simply be a single Xeon processor box with mirrored SATA's and a GB of RAM. And email on a similar blade. Then I could run a Dual Quad Core 2.66Mhz Xeon blade with 12GB of RAM as a LTSP server. I never realized how configurable such a server was until now. It would also be very cool to have a single 7U chassis running every server in our organization. I could even have a blade running a Windows Terminal Server and another running some Windows Application server. Could be neat. But for $7400 I can buy a stand alone Dell 1900 with dual Intel Quad Core 2.33Ghz 1333Mhz FSB processors, 16GB RAM, mirrored SAS 36GB drives, connect my existing powervault 220s for /home, and 2 dual GB NIC's teamed for load balancing. Where as the chassis for the blade server is $7500 or so alone + the cost of each blade. So at this point I am considering the above server to run as my all in one LTSP server for 100 clients to start, keep my current Dual Xeon 3Ghz 4GB RAM box as my mail/LDAP server and then just add more app servers down the road for any apps that drag the thing down. I also can't decide if I should just buy all new terminals right away, or just run my iMacs as clients and replace as they die.

I've run 500 users on a Sun Ultra 5 back in the day (Postfix + Courier-IMAP) without stressing the box. However, I still prefer to have email on a separate box. The reason for that is security. If the cracker compromises one daemon (e. g. sendmail), he doesn't own a bunch of other stuff, too. For stuff like LDAP, email, and Web servers (relatively low CPU requirements), I'd start looking at one of IBM'S POWER5 boxes that let you do LPAR's. Yes, the mainframe LPAR ability now exists at the microcomputer level. With such a box, you can make LPAR's as small as 1/10th of the CPU, and you can make your LPAR resource allocation somewhat dynamic, if you wish, to adjust for changing requirements/loads. LDAP can go in one LPAR, email in another one, Web in another one, etc. For those who aren't familiar with LPAR's, think of it as having sort of an "unlimited-license VMware", but built into the hardware; you have separate "virtual machines." And yes, they run GNU/Linux beautifully. That's how I'd be looking at consolidation. The POWER5 boxes ain't cheap, but neither is a good multi-core x86-64 server. > Could be neat.

Additionally, they've proved to be more susceptible to breaking; we've had to RMA quite a few of them.

Isn't that one of the major points of LTSP--you *don't* need to stay on the "upgrade treadmill" like with Wintel? I'd keep those iMac clients and replace them as they die.

The problem I have with any of the blade or large box products is that your future upgrade path is limited to either whatever this vendor provides or swapping out the whole thing, plus it really doesn't make sense to use the same type of hardware as a file sever and an pplication server. I think a good approach would be to take an older but heavy-duty (dual power supplies, hot-swap drive bays, etc.) server and run something like openfiler (http://www.openfiler.com/about/) on it as the account/home dir server, and then use fast but not heavy-duty boxes as the app servers, planning to replace them frequently to keep up with processor technology. By the way, has anyone tried openfiler's LDAP with k12ltsp clients? -- Les Mikesell les at futuresource.com From william at fragakis.com Tue Mar 13 17:47:35 2007 From: william at fragakis.com (William Fragakis) Date: Tue, 13 Mar 2007 13:47:35 -0400 Subject: [K12OSN] united streaming and mplayerplug-in: recipe Message-ID: <1173808055.8091.42.camel@server.ltsp> Hello all, I hope this isn't redundant - the last posts on the issue had videos played from saved files via mplayer or other players. I've gotten mplayerplug-in to work with unitedstreaming.com and cnn.com videos within firefox (.wmv format). I've used this only in K12ltsp ver. 6, ymmv. It does work in the classroom as I've updated a couple of servers plus my own home server without problem. steps (as root): 1) install mplayer and mplayerplug-in from livna (if you are updating mplayer and you get a conflict with ffmpeg, remove ffmpeg and mplayer and reinstall mplayer) 2) create the directory /usr/lib/win32 - the default permissions 755 (iirc) are fine download the codecs for various formats from http://www.mplayerhq.hu/design7/dload.html under "binary codecs" You will be downloading essential-20061022.tar.bz2 Extract the codecs and move them into /usr/lib/win32 and give them the same permissions as the directory (if they didn't by default) mandatory disclaimer: the codecs are subject to certain licensing restrictions in certain countries, blah, blah. 3) edit /etc/mplayer/mplayer.conf under the audio section # Specify default audio driver (see -ao help for a list). #ao = alsa # Use SDL audio driver with the esd subdriver by default. ao = sdl:esd (ie comment out alsa as the default and uncomment sdl:esd) 4) drumroll - the part that was giving us all fits: no sound in mplayerplug-in edit /etc/mplayerplug-in.conf uncomment the ao line and change it to either (they both seem to work) ao=sdl:esd or ao=sdl 5) Annoyingly, if you open the config panel of mplayer plugin from the browser window (right clicking), it will show oss as the audio output. Ignore it. That may be correctable in the source code but I haven't looked at it yet. 6) Optional: if you are getting "couldn't resolve name for af_inet6" errors in mplayer, add the following line to /etc/mplayer/mplayer.conf prefer-ipv4 = yes (thanks: http://lists.mplayerhq.hu/pipermail/mplayer-users/2006-May/060636.html) 7) ignore plugiin warnings on cnn.com, click "continue, etc." Enjoy, William Fragakis morrisbrandon.com From robark at gmail.com Tue Mar 13 17:53:30 2007 From: robark at gmail.com (Robert Arkiletian) Date: Tue, 13 Mar 2007 09:53:30 -0800 Subject: [K12OSN] AMD offers $250,000 prize to help Third World get online Message-ID: Just noticed this on the Edubuntu list.

First off, If you have a computer pulling more than 10 amps you have a problem. One of the advantages of using thin clients is lower power consumption. A diskless client operates on less than 1/4 amp of power. The power supply in most desktop PC's are going to be way overkill and will waste power. I know it means spending money, but if you replace those big power supplies with low voltage ones you will greatly reduce the power consumption. The power supplies used for automotive applications are a great way to go. You can use something like this item: http://www.mini-box.com/picoPSU-80?sc=8&category=13 and share one 12v power supply between multiple boxes. Right now I'm putting together a proposal for a mobile system using just these items. The spec is they need 6 workstations with full internet access. They also need to run all of these off a standard automotive electrical system. I've chosen the Jetway 1.2Ghz Mini-ITX boards for the 6 stations. With a rated power consumption of 9 watts they came out on top. My tests show that with a keyboard, optical mouse and running they actually consume about 15 watts. I'm still waiting on the server parts, but it will consist of a 2 Ghz Mini-ITX board with two 2.5" sata laptop drives. I don't expect it to have a really large draw. I hope that by using two drives I can get the speed up a bit so things don't lag too much. Since firefox is 99% of the usage it is not that big of a deal. I also have some testing to do on monitors yet. CRT's are going to be a power hog. LCD's are a great way to go to reduce power. Again they cost money, but will save in the long run. The big power hog in traditional computers is hard drives and fans. Reduce those and reduce power consumption. In case anyone is curious how it all comes together. The server will be connected to a Linksys router with a pcmcia card connecting it to sprint broadband wireless. This would be a great setup for the internet equivalent of a book mobile.

Or steer me I am not an electrician but I do teach basic electric circuits in physics. The basic equation for power is P=IV (Power=VoltagexCurrent) So 120 Volts (which is a north american standard) x 20 A of current equals 2400 Watts of power. Now if you remember those old boxes probably have 200W power supplies max + monitor ~75W. Add another 25 for safety. So I would say 300W/box is reasonable. Although less would probably work because I doubt they would draw the max of the PS unit. So with a 20A circuit (2400W) that equals 8 machines working at full tilt. Now compare that to an ebox 2300 + and a 19in lcd monitor consumes. 15W + 40W Plus the server, don't forget. > to a good site?

The basic equation for power is P=IV (Power=VoltagexCurrent) This is why things get confusing. Power supplies in computers are rated by the DC side of the power supply. The power supply on my workbench is rated at 150 watts. Here is the real data from the sticker on the side: AC Input: 110v 3A DC Output: +3.3v 9.5A +5V 10A +12V 7A +5V 1A -12V .2A Max +5V + 3.3V = 123W Combined Max Total Output = 150W So as you can see it can potentially pull a lot more than the 150W rating implies. A supply rated at 330W can actually pull up to 5 amps. It all depends on how much hardware is in the box. A diskless client should have as small of a power supply you can find. Bigger supplies will have more parasitic loss (heat).

I didn't consider this. So the efficiency of the PS unit is a factor. Nothing is 100% efficient. I think if my memory serves me right Europe has a law which requires a certain kind of more efficient PS than here in North America.

That is 2/3 wasted electricity. Now, if you go to terminal services (with LTSP or whatever) you won't need hard drives so those 20 computers will use less energy anyway. Could be as much as 15% to 20% less energy than the fat ones in the offices. Also, look around the buildings and see how many unoccupied rooms throughout the day are left with the lights on. When the students are at lunch, for example, look at those classrooms burning electricity for no reason. Help them to realize that comuters are not the only thing that uses a lot of electricity. If the computers you have in your room do not trip the breakers, and the breakers have NOT be compromised, there is no worry of how many there are. Just make sure you don't use inferior power cords and strips and that you do not overload any strips or other eguipment. One computer per circuit is rediculous! I have been in MANY highly rated computer labs and have NEVER seen in any of them, one computer per circuit. I do not condone loading that circuit until it trips the breaker because that is hazardous. Get your maintenance man to use his clamp-on ammeter on your circuit when you have those computers on and see how much power they use. Then remove the hard drives. . .

What that power rating means is what the power supply is *capable* of putting out. That doesn't mean that it actually *is* putting that out all the time. The only time you'll see that max power rating is if you stick a load on that power supply that draws that much power. Regardless of your voltage, in order to have a load, you must draw current. The less current you draw, in accordance with P=IV, the less power you draw. What that means is that you can disconnect the hard disk drive and CD-ROM drive, thus lowering the load that the computer's power supply sees. Now, there's only so much you can do without un-soldering parts from the motherboard. :-) But any time you can power down a mechanical device like a disk drive, do so. Oh, if you're netbooting off the NIC's boot rom, you might as well unplug the floppy disk drive, too. Furthermore, that 300W rating on the power supply *is* accurate. That's the total output that it can handle at any one time, out of all outputs, combined. Sure, if you add up all the power ratings from the 5v, 12v, etc. outputs, you might get a figure higher than 300W. But if you actually try sucking max power out of each input simultaneously, you *will* blow up that power supply. What happens is that if you want to take the entire 5v current rating, you must decrease your 12v current draw by an amount to keep your total power usage under, in this example, 300W. That's why folks with these multiple CPU cores, super-duper-hot video boards, multiple hard disks, light kits, etc. in their computers need these insanely huge power supplies. Along with their 5v needs, their 12v needs also just went sky-high, and they can't borrow from the 5v side w/o shutting down the motherboard...or blowing up their 300W power supplies, thus probably frying said motherboard and expensive CPU(s). That's why they go buy those 550+ watt monsters. Now, that said, it is true that there is some inefficiency with power supplies. Gotta keep those capacitors charged up, you know (there are also inductive and resistive losses). The bigger ones, even if they're very efficient, do indeed lose more juice than a little one of equal efficiency; they're just bigger. But what really matters most is the load you put on it. So, start pullin' those disk drives! If you want to further reduce your electrical requirements, look into LCD screens. They use about a third of that which an active CRT of the same screen size uses. --TP _______________________________ Do you GNU!?

There was central APC 5000VA ups, and when all computers was tutned off, ups shows very many amps load currency. And when we pluged out monitor cords - load was 0 AMPS again. Those monitors was totally killers. I never seen it before or after. But there was one seria of 15" CRT monitors - even when monitor was sleeping and yellow led was turned on - power they needed was allmost like some kind of working heaters.

A couple of things to keep in mind - per the US National Electric Code, the continuous load on a 20A circuit shouldn't exceed 80% (16A) and you do need to allow for load surges when you start equipment. The engineers typically allowed for several PCs per circuit, so I don't understand what Dell is telling your school. Do you know if your room has dedicated circuits or does it share with other classrooms? My experience is a typical PC usually doesn't draw as much as the power supply is rated at - maybe 150W during routine use. The stickers on equipment are conservative and allow for maxing out a PC - fast CPU, high-end graphics card, extra drives, memory etc. An old PC with the hard drive, CD, floppy etc disconnected will use a lot less power than a "fat" PC. For instance, an old Dell P3 I use with LTSP only draws 43W when running as a thin client. Coupled with an LCD monitor, you are looking at roughly 90W per station. I've had great success with HP's thin clients - base models ($200) work great with LTSP, and draw around 18W when running. You should be able run the lab on LTSP with less power (and heat and noise) than you have today with 20 full PCs, even taking into account a decent server, UPS and network switch. Estimate with old PC thin clients: 1 Server & LCD monitor - _maybe_ 300W (no redundant power supply) 20 old PCs, with CD, HD etc disconnected (45 W each) with LCDs (45W ea) - 1800W Network switch - less than 100W Lab total = 2200W (18A) Estimate with new thin clients: 1 Server & LCD monitor - _maybe_ 300W 20 thin clients (20W each) with LCDs (45W ea) - 1300W Network switch - less than 100W Lab Total =1700W. (14A) The estimates don't factor in the power needs of a UPS for your server or allow for anything else to be plugged in, but you get the idea. CRT monitors and not having the budget for thin clients hurts the equation, but if the school has some money for new PCs, you can get 5+ thin clients for the cost of a nice new PC.

The PC was a Gateway 450Mhz PII (this was some time ago) with a 20GB HD and a 15" LCD monitor. The terminal was a Disklessworkstations LTSP 150e with the *same* 15"LCD monitor. The measurements were made using "apcupsd" with and APC Back-UPS XS 1000. This gives power draw on the AC side in percent of capacity resulting in "Volt-AMP" (voltage x amps) units: PC & LCD = 120VA Terminal & LCD = 60VA The PC measurements were with an "idle" HD, if it were seeking/reading/writing it would draw slightly more and system startup would draw significantly more. So the PC draws about 1A (when idle) and the terminal draws about 1/2A. More modern PCs will likely vary from this, but the old PC I used is typical of the "recycled" PCs used as terminals with LTSP. -- "History doesn't repeat itself; at best it rhymes." - Mark Twain | John Lucas MrJohnLucas at gmail.com | | St. Thomas, VI 00802 http://mrjohnlucas.googlepages.com/ | | 18.3?N, 65?W AST (UTC-4) | From veewee77 at alltel.net Wed Mar 14 11:43:41 2007 From: veewee77 at alltel.net (Doug Simpson) Date: Wed, 14 Mar 2007 06:43:41 -0500 Subject: [K12OSN] electricity use In-Reply-To: References: <45F2B47B.7040804@stmarys-school.org> <774593a20703100730sd7ca46apbd604f6514324ef5@mail.gmail.com> <1173545059.3204.6.camel@BACI-W> <45F2E21A.5040104@cmosnetworks.com> <20070313232740.GA10800@clubber.owens.net> Message-ID: <45F7DFED.6030501@alltel.net> In this discussion, we need to clear something up. Just because a power supply in a computer says 300W does NOT mean that that is what it makes the comuter draw regardless. That number is the maximum that that power supply is capable of delivering to the parts in the computer. Changing from a 300W to a 100 watt (if you can) won't change the draw of the computer much, if at all since the parts in the computer use what they use. Think of it this way, you have a giant, MEGAWATT power supply connected to your house, but your house only *draws* a very small fraction of this power. The computer has a 300W (rated) power supply, but the components may only *draw* a total of 100W. The other 200W is not wasted. You are just using 1/3 of the *rated maximum* of that power supply. Hope this clarifies this. . .

Perhaps a solution is to purchase some inexpensive UPS's and use them buffers between the PC and the circuit to handle spikes (power on for example).

There isn't really any significant difference in the LTSP parts, as both versions of K12LTSP incorporate verion 4.2 of LTSP. So, your users won't see any benefit. Considering the risk and potential downtime, I don't think this is the time to change a production system. Now, just to make things interesting, betas of version 7, based on Fedora 7, is due out sometime in the next few months. So, the real question becomes, come fall, do you want to be using version 7, which will be brand new and will be a significant overhaul in the LTSP parts; or do you want to go with tried & true and stick with version 6? Deciding whether to use version 5 or 6 is fairly easy since they are similar--there are some differences, e.g., getting afpfs working is much easier with version 6--but they're narrow, not affecting most sites. Sound should be better in version 7, but that remains to be seen. Petre Joe Korzeniewski wrote: > I guess I still have a little bit of M$ upgrade fever left in my system.

V * A = W is true for DC (direct current), for AC, say 120V, one must use a "power factor" arrived at experimentally. It is around .9 for UPSes, around .8 for AC motor loads. 2. 20A rated circuit will -not- deliver 20A current for long - the circuit breaker will disconnect at 18A. So from 1. and 2. it follows that one won't get much more than 1,950 Watts of power from a 20A 120V AC outlet. On the other hand, the specs on power supplies are the maxima that can be drawn. If you remove disk drives from old boxes, the typical load is below 150W. The Dell reccomendation of one computer per 20A circuit has more to do with harmonic distortion introduced by the power supply than with the load. Take all this with some distrust - I used to be a mathematician. What you might want to do is to borrow a good meter (with the owner?) and measure the real power consumption. You will be surprized how little the stations draw and how much the server does. julius From william at fragakis.com Wed Mar 14 14:44:54 2007 From: william at fragakis.com (William Fragakis) Date: Wed, 14 Mar 2007 10:44:54 -0400 Subject: [K12OSN] united streaming and mplayerplug-in: recipe In-Reply-To: <20070314060140.5BF6F73042@hormel.redhat.com> References: <20070314060140.5BF6F73042@hormel.redhat.com> Message-ID: <1173883494.12266.71.camel@server.ltsp> Hi, Frankly, I don't really have intelligent answers to most of your questions. The only thing I can tell you and what inspired me to try this is that if you choose "sdl" as the audio option in mplayer, a) it works (which was the first hint) b) it was really late and I was too lazy to compile my own mplayer or plugin c) it uses the sdl:esd option for the audio driver in the config file. Seeing the esd portion of that and the comment in the config file that using the sdl option meant using the esd sub-driver prompted me to try that route. # Use SDL audio driver with the esd subdriver by default. ao = sdl:esd I was surprised it worked because running mplayer -ao help to list the available drivers didn't show esd, only sdl If I had to speculate from what I can gather from the libsdl.org home page in only a cursory reading, sdl provides a conduit for esd http://www.libsdl.org/intro.en/usingsound.html Perhaps the more learned among us can help you further. regards, William > Message: 11 > Date: Wed, 14 Mar 2007 15:16:49 +1300 > From: "Krsnendu dasa" > Subject: Re: [K12OSN] united streaming and mplayerplug-in: recipe > To: "Support list for open source software in schools." > > Message-ID: > > Content-Type: text/plain; charset=ISO-8859-1; format=flowed > > What does sdl:esd do?

I have been running Fedora on my workstation since version 1 and use CentOS for servers at my company. I also happen to be a volunteer in the sysadmin team for a small student organisation for a few years now. This organisation doesn't have an IT budget really and the current setup consists of a server (well, desktop) running Debian (serves Samba shares, runs BackupPC, handles mailinglists and serves some wiki's and other simple internal web applications) and ~8 workstations defaulting to Ubuntu, but some of them dualboot Windows XP (the accounting software only runs on Windows). These workstations (a few different models) are not very powerful machines (around 450 MHz or so). I was thinking this is an ideal place to introduce an LTSP server. They are already using OpenOffice.org, Firefox, Thunderbird and Scribus (we started a move to Linux a couple of years ago, Windows licenses were just to expensive). With an LTSP server I think the workstations should be a lot speedier than they are now. Buying new computers has been an ad hoc business until now. "Oh, a computer broke, we need to get a new second hand machine!" I'm trying to figure out what hardware I need for an LTSP server that could serve 8-10 workstations for the coming years and what kind of money it would take to set this all up. Since there is no real budget I'm looking for a cheap solution. If I can convince them that in the long run this is cheaper than keep going with fat clients I might be able to get some money for this (I hope). People are a bit sceptical though. The sysadmin volunteers are not on site that often and they fear an LTSP server going down and not being able to work at all. I might be leaving the sysadmin team at the end of this year, so we'd need something that's low maintainance. Of course only having to admin one machine (the server) should be less work than keeping 10 different machines up to date. But there's a bigger single point of failure as trade-off. Right now, when the server is down they can't get to their files, but at least they still can surf the internet and use email. Any recommendations for hardware? We are in The Netherlands, so if anyone has any recommendations for hardware you can get here at interesting prices, I'd be more than interested. I'm planning to do a K12LTSP 6 install on an old borrowed 6-way (!) 450 MHz server with 2 GB RAM and a SCSI RAID array. I'm thinking that for a production server we should probably get a fast dual-core processor and 1-2 GB RAM? I guess SATA (probably RAID-1) should be fine? Currently everything is on 100 MBit switches, I think we'll need a gigabyte model attached to the server? Still debating whether to use the LTSP server as a gateway or not.

Sound should be better in version 7, but that remains to be seen. Petre Joe Korzeniewski wrote: > I guess I still have a little bit of M$ upgrade fever left in my system. I always like playing with the new features of the latest version. If there isn't a significant advantage in upgrading right now I will take your advice and hold off until I can do a new clean install. Many times on my desktop systems (linux) you just click upgrade and you have the latest OS with no strings attached (servers can be a different story sometimes though). I was just wondering if anybody had nice clean upgrades to talk about or if it was more of a chore than it is worth.

I know SDL is a library used to build games. Their homepage says: "Simple DirectMedia Layer is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer. It is used by MPEG playback software, emulators, and many popular games, including the award winning Linux port of "Civilization: Call To Power." But I guess it also can be used to get your audio in mplayer to work. :o) Nils Breunese. -------------- next part -------------- A non-text attachment was scrubbed...

It stopped working as of March, leaving me to suspect that an update caused the issue. The behavior is strange. When a student connects a thumbdrive into the terminal, it actually mounts! However, they can't see any of the contents that are presently on the drive. Here's the strange part, they can actually write to the thumbdrive, meaning, create new files and save them. Files created when mounted to the terminal will become visible again if the thumbdrive is unplugged and plugged back in. HOWEVER, as explaned above, any files that have been written on the thumbdrive elsewhere are NOT visible. This makes it hard for students to bring in their homework created on their personal machines into the school. I have gone through the troubleshooting steps using the USB wiki on the LTSP website, and couldn't pass Step 4. Perhaps our problem is here? How can I get the workstation to know the hostname? Step 1: Disable X. N/A. Have shell loaded on second screen. Switched to second screen. Step 2: Determine Version Number. Output is 4.2 Update 3. Step 3: On workstation, lbuscd confirmed running. /tmp/drives/ shows a folder representing the thumbdrive inside. Step 4: hostname returns the output = (none). I suspect this may be our problem. I have however followed the steps in the installation section by adding the line "get-lease-hostnames true;" to the dhcpd-k12ltsp.conf file, but it made no difference after restarting dhcpd and rebooting the terminal. The dhcpd-k12ltsp.conf file at the part where I entered this line is below. get-lease-hostnames true; shared-network WORKSTATIONS { subnet 192.168.0.0 netmask 255.255.255.0 { range dynamic-bootp 192.168.0.100 192.168.0.253; use-host-decl-names on; option log-servers 192.168.0.254; get-lease-hostnames true; From nils at breun.nl Wed Mar 14 21:02:43 2007 From: nils at breun.nl (Nils Breunese) Date: Wed, 14 Mar 2007 22:02:43 +0100 Subject: [K12OSN] K12LTSP server for a student organisation In-Reply-To: References: <9CF451D8-A420-4959-9FA2-E3A50B2FE429@breun.nl> Message-ID: <23AD1FA1-5484-4C26-A37E-CEDB1CB0D2AA@breun.nl> Robert Arkiletian wrote: >> [ asking advice for hardware for an LTSP server for ~10 clients] >> >> Any recommendations for hardware?

Although it sounds like a nice server (ram and > disks) and it will probably be okay. I know speed won't be comparable to a shiny new server, but the point is just to have demo/test system and then decide whether we want to go with an LTSP setup. This borrowed server is really a monster. It's huge and it makes a lot of noise when powered on. You can put in up to 4 power supplies in and it has 4 GB RAM. We'll only put in 2 GB for the test though, because it takes forever to memtest all that memory and you can't skip the memtest. :o( >> GB RAM and a SCSI RAID array.

We already have two 100 Mbit switches although they're pretty low budget consumer models, so I'll use those for testing next weekend. So I wouldn't really need gigabit ethernet in the server either? We're looking for a cheap solution, so I'd love to not get anything we won't need. Nils Breunese. -------------- next part -------------- A non-text attachment was scrubbed...

I am using two k12ltsp servers to do dhcp to windows clients as well as thin clients on two subnets. The windows clients are pointed towards our windows 2003 DC which is the dns server as well. Windows 2000 client boxes show up fine in the dns pool but no windows xp boxes ever shows up? When I do an ipconfig /all all the client boxes shows as seeing the actual windows 2003 server as being the dns server. The last couple days I have tried hammering the AD a bit such as changing from default " secure connections only"> to> "non secure and secure" All machines can do name resolution fine,so Im not real concerned about it. But it just seems strange that 2k boxes are listed and xp boxes are not. I have disabled win firewall as well to see if this may have had anything to do with it.

K12LTSP handles multimedia pretty well, but it depends a bit on what you mean by 'multimedia'. Do you mean streaming video from websites? Mplayer and the mplayer plugin for Firefox work pretty well. William Fragakis just posted instructions to this list the other day on how to get this all to work. It's pretty simple. > 2.For 30 terminals how many servers would be required assuming we have > to use multimedia apps like flash and other interactive elements? You can probably get away with a single server for 30 clients. I'd suggest either a 2Ghz or greater dual processor or dual core system, with 4GB of RAM. You should have a good gigabit NIC in the server, and the switch should have a gigabit port for the server, and 100Mb ports for the clients; typically, these come as a 24+2 switch with 24 100Mb ports plus two 1Gb ports. Of course, you could use two servers, each with 2GB RAM, each with a good gigabit card and a 24+2 switch. But that costs more than a single box, but eliminates a single point of failure. > 3.

Heavy Flash in full screen mode applications is reported to be a slow down. Without which even 100mbps network is good enough. But with the costs of 1/2 port gig and 30 port 100mbps swithces bein low you would rather have gig uplink to switch. > > 2.For 30 terminals how many servers would be required assuming we have > > to use multimedia apps like flash and other interactive elements? > You can probably get away with a single server for 30 clients.

As I said above one server with maxed RAM and SCSI disk is good enough for these numbers. If you can go for dual core CPU it would be even better. But my approach would be top reduce points of admin to minimum. -- Regards, Sudev Barar From shishirjh at gmail.com Thu Mar 15 03:31:40 2007 From: shishirjh at gmail.com (Shishir Jha) Date: Thu, 15 Mar 2007 09:16:40 +0545 Subject: [K12OSN] LTSP detailing required for Nepal In-Reply-To: <774593a20703141937o14c9a31cpa0089130c809fa58@mail.gmail.com> References: <6a2207a10703140947r66b2f2ean3369771b2b6355fd@mail.gmail.com> <45F8AA61.1050403@scheie.homedns.org> <774593a20703141937o14c9a31cpa0089130c809fa58@mail.gmail.com> Message-ID: <6a2207a10703142031p50697aedm511a1392a8d61049@mail.gmail.com> Thank you for your response, How could using 2 servers in two different subnet supporting 15 clients each in 100 mbps network do for the requirement do.

Even if they are 32MB RAM (yours are 64MB) you can always enable swap memory. Two server on SAME sub-net with round robin dhcpd setup would be better. See previous posts / wiki for how this is to be setup. One server would also do NFS export of /home and the other would do NFS mount of /home directory if individual user accounts are to be used. If only guest accounts are to enabled then even this is not needed. IMHO hyper threading (HT) does not really bring in as much benefit as dual core CPU's do, and today they are almost as (in)expensive as P-IV's. Max the RAM I would rather put 4GB in one server than make two servers. Save that money of second server and put it in a SCSI drive (two with mirroring would be even better). 100mbps network will do the job. Have the 1000mbps connection between server and switch it would be better. If you have two servers then you may need gig connection here also. > By flash i meant flash content prepared in Macromedia Flash/Director for > community to be taught about HIV/AIDS and other health issues after the > school is over for general information spread Try this on a single server and client and monitor network traffic with something like iptraf. You would get idea of how much network traffic is likely. IMHO this would not be issue if you use server-switch on gig link. Again try this program on desktop and monitor top and free -m for load and memory. HTH -- Regards, Sudev Barar PS: Where are you located?

You don't know if you're going to be running 14-15 simultaneous sessions of TuxType. Remember that TuxType sucks up 73Mb/sec per session. Gigabit Ethernet on the server is important for this. TuxMath is pretty similar. --TP From CSYPERSKI at DUPAGE88.NET Thu Mar 15 12:32:15 2007 From: CSYPERSKI at DUPAGE88.NET (CHUCK SYPERSKI) Date: Thu, 15 Mar 2007 06:32:15 -0600 Subject: [K12OSN] Oen source POS program Message-ID: To make it a little easier on anyone wanting to test it out, I have also posted a VMWare Image.

Anything past that and the collisions will slow things down to a crawl. Flash will seem like it's stuck in the mud. For 10 clients, you could easily use a Pentium D (dual core) or even better an Athlon x2. For the minor increase in cost, go to 2 gb of ram. Two sata 7200 rpm 8-16mb cache drives in a RAID 1 or a single 10k SATA drive are plenty fast enough. We've been building Athlonx2 4400-ish boxes for under $1000 US to serve a classroom of 20 students with 2gb RAM, 10k SATA drives in RAID 1 and gigabit out to the clients. You could get an off-the-shelf AthlonX2 for even less. The RAM, faster drives, good motherboard and better case though, for us, were worth the extra cost.

The power problem, incidentally, is one of the reasons the OLPC is considered to be so crucial. Its power profile: * 10 watts going full-bore (heavy networking, heavy display repaints) * 3-6 watts typical usage * <1 watt in e-book mode (scrolling only, monochrome display mode) It might be very interesting to see if it's possible to join the server compute power of LTSP with the low-power OLPC client. --g ------------------------------------------------------------- Greg DeKoenigsberg || Fedora Project || fedoraproject.org Be an Ambassador || http://fedoraproject.org/wiki/Ambassadors ------------------------------------------------------------- From gdk at redhat.com Thu Mar 15 13:48:11 2007 From: gdk at redhat.com (Greg Dekoenigsberg) Date: Thu, 15 Mar 2007 09:48:11 -0400 (EDT) Subject: [K12OSN] K12LTSP server for a student organisation In-Reply-To: <20070314232920.GF12964@clubber.owens.net> References: <9CF451D8-A420-4959-9FA2-E3A50B2FE429@breun.nl> <20070314232920.GF12964@clubber.owens.net> Message-ID: On Wed, 14 Mar 2007, Rob Owens wrote: > You can always leave a local installation of Ubuntu or Windows running > on the workstations, but have them default to booting off the LTSP > server.

This is one of the *best* things about LTSP; you can run it practically as an insurgency. :) Seriously. If you have an old server that you can install on, the cost of introducing LTSP to a lab, for trial purposes, is basically zero.

When asked why, the response is typically of the form 'because that is what we want'. Now, this is going to impact the use of K12LTSP (or the adoption of anything that is not MS-centric). So, has anyone come up with a legal requirement that would make requiring the use of a specific browser by a specific vendor on the vendor's hardware illegal? I don't see how Section 508 can be used to get around this, but perhaps someone on the list knows something. Delaware is a very very very MS-centric approach to IT. In fact, the Delaware CIO boasts about the close ties of Delaware and MS. He was formally the Verizon lobbyist to the state. We are a small enough state (2 degrees of separation for most people) that if there is something questionable about the proposed approach, it can be changed but only with really good reasons.

Recently the school went state-wide with a web-based IEP system for special-ed students. I know they made a good attempt at testing on multiple platforms with multiple browsers, as my wife was asked to be in on the testing, and I saw the list of browser/os combinations they were wanting testers for. However, our state department of ed is in bed with Apple instead of Microsoft. They used FileMaker for the database backend, which for that kind of load, is incredibly inefficient. It has been my expirence that Apple admins tend to over estimate the efficiency and power of their servers. The IEP program was very clumsy when it was a stand-alone program, opening up 12 windows just to start the program. It looks all nice like an apple program, but looks only get you so far.

Government bureaucrats think in terms of what they can *legally* get away with. The only way to stop stupidity or sweetheart deals is via legal means.

Get to know your local state reps. Explain how IE-only plans of the DOE will shut out ALL the Macs in schools, since IE isn't being maintained for Mac any more, how the modern approach is to code to open standards so people are not locked into specific vendor's products. Remind those reps that 20 years ago, all the various mail services--Sprint, CompuServe, AOL, etc.--were proprietary and didn't talk to each other. The Internet changed all that, and that's why it stomped those proprietary services. The DOE's approach is a reversion back to proprietary approaches that don't do the job. Get the reps to understand that the DOE's strategy will end up costing the schools MORE money because they'll have to buy expensive equipment (Windows boxes) just to accomodate the DOE's shortsightedness. Then ask the reps to help the DOE adopt a more open approach, e.g., something that complies with W3C standards rather than just accomodating one vendor. (There's an idea brewing here: Having government officials say they have great connections with a private business, such as your CIO has done, reminds me of the line from Styx's "Too much time on my hands": "I've got dozens of friends and the fun never ends, that is, as long as I'm buying". Government shouldn't really have close ties to any vendors. Private businesses, sure, they can have ties with whoever they want, they have no obligation to be neutral. But government is different. Unfortunately, it sounds like your CIO doesn't quite grasp that. Who *doesn't* have good ties to their vendors? The vendors are supposed to be your 'servants', although there's a price.)

I contacted my state Senator and (old) Representative last year (they live 7 and 4 houses away, respectively), but even when told that adopting a different approach to IT could save 50% plus in IT costs (with data to back it up), and also provide a better (more rounded?) IT education to students, they still said that they needed to defer to the experts (State DOE, CIO) on these decisions. I now have a new Rep (about 1 mile away) after last fall's election, so I will contact him and see if he is more willing to question the status quo. Of course, this is the same House and Senate that passed sunshine laws which apply to everyone except themselves (specifically exempted themselves in the law).

Their purpose is not to push MS applications out of gov't. Rather, the bills are recognition that a state, for reasons of sovereignty, cannot and should not have its documents in a format that is controlled by a private vendor. It isn't that DE should adopt ODF (although that would be good, too), but rather to point out that the trend is AWAY from proprietary interfaces, to open vendor-neutral standards. Then ask the question, why is DE actively moving backwards in this area?

If you can get a bios with a nonbuggy version of PXE, then here's what you have to do. Add the "-r blksize" option to tftpd at startup. On Fedora, this means adding that option to the tftp file in the xinetd folder. The other thing that I had to do was "echo 1 > /proc/sys/net/ipv4/no- ip-pmtu-disc". Make sure that runs every time the server starts up. Those two things made the old deskpros boot just fine. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iEYEARECAAYFAkX5cK8ACgkQfqZR3ThMfXTfGgCfVlvtiJ4ClNoIkitUEl5uo7A3 akgAn0NBmVQRYD9huOPrMea1rfY0tiYd =WvGu -----END PGP SIGNATURE----- From olivier.mugnier at laposte.net Thu Mar 15 14:41:49 2007 From: olivier.mugnier at laposte.net (Olivier Mugnier) Date: Thu, 15 Mar 2007 15:41:49 +0100 Subject: [K12OSN] OT: Consequences of 'net use /home' References: <9bd317560703100538w684bd3berb95bbc6f3e71da21@mail.gmail.com><003301c763f6$d81ea4a0$0100450a@olivier> <9bd317560703150722ka330a76o5ccb61750039ba55@mail.gmail.com> Message-ID: <000001c7671d$d9629ea0$0100450a@olivier> off-line....

Quick question about yum itself. One of the fellows I work with has a unit from Green Computer (a Power Elf) that I believe is in part based on e-smith's offering and uses yum to do it's updates. The box is no longer able to check in to their update server and checking the logs looks like it hasn't checked in in a long long time (but let's not go there). The yum.conf file is: [main] cachedir=/var/cache/yum debuglevel=1 logfile=/var/log/updates.log pkgpolicy=newest [updates] name=PowerElf 2.0 updates baseurl=http://www.greencomputer.com/pe2updates/yum/updates I can reach the baseurl from the unit using curl - and can see all the packages. When I do a yum -d 10 list (to crank up the debug) it sticks on: Gathering package information from servers server name/cachedir:PowerElf 2.0 updates-/var/cache/yum/updates Getting headers from: PowerElf 2.0 updates getting header.info from server Exiting on User Cancel but I can access the header.info fine from either a webbrowser or by curl on the unit itself. The support person for the company is insistent the problem is a firewall. Could it be? Does yum change protocols and use something other than port 80? Am I missing something else obvious? Thanks all - Scott Sherrill From vince at totalsense.com Thu Mar 15 17:20:54 2007 From: vince at totalsense.com (Vince Callaway) Date: Thu, 15 Mar 2007 10:20:54 -0700 Subject: [K12OSN] OT: Required use of IE by State DOE In-Reply-To: References: <45F97841.30404@scheie.homedns.org> Message-ID: <1173979254.21860.45.camel@dbserver> A little over 10 years ago I served as an aide in our states Senate. The Senator I worked for was an old friend and technically pretty savvy. One of the bills he introduced was a somewhat insignificant sounding bit of legislation. It was to allow the states archivist to store documents on CD-ROM. There was an amazing amount of fighting over the wording. We of course wanted to make sure that the storage was non-proprietary. There were several big companies that sold specialized systems that certainly did not want any language locking them out. The final bill that became law authorized the archivist to create a committee to oversee digital document storage. So far this has worked. Now for my suggestion as an insider on how to deal with this. First off as a low level state employee your opinion on this will pretty much be ignored. Unless you are already tight with a legislator they probably wont give your issue much thought. Just speaking from experience. Your BEST bet is to get the parents involved. The approach is to get the parents and students to complain that the DOE is discriminating against low income students. By requiring the use of proprietary software (IE) it reduces access to only those who can afford to spend money on MS Windows. MAC and other users will be locked out. Start with your Senator and Reps. You will find it easier to get an appoint with them than someone out of your district. The BEST person to get the ear of will be the chair of the Senate education committee. I assume your state has one. Unless they are from your district it will be hard to get an appointment. Get the attention of the legislative aide. They are not only the gatekeeper for the Legislator, they also do 99% of the work. They will be the one responsible for doing any research and scheduling. You WANT them to understand. Your best case scenario is to get a meeting with you, the Legislator and the lobbyist for the DOE in a room together. Don't expect more than a 15 min appointment. You will probably leave the room frustrated. The Lobbyist will probably just give a line as to "I will look into this". Don't get frustrated, this is a good thing. When a request comes from a Legislator for an agency to explain why they are doing something it carries weight. It will go down the food chain to the IT guy who made the decision. He will have to justify why the decision was made. A good lobbyist will insist on a credible answer. The reason is he wants to come back and show that he has taken care of the problem. It gets him good ol' boy points when he comes back and asks the state for things like more funding. I realize this is long winded. Despite what schoolhouse rock taught us the political process is not very simple. It is in fact very frustrating.

If this is the issue, you need to set the proxy information for yum to use the proxy and also tell the proxy not to cache info. the proxy info can be set in the config file for yum. Another issue I have is that the baseurl had to be modified slightly. I will be at the school tomorrow and can provide an example if needed then.

I am not a state employee. I am just a parent volunteer at the school for the last 6 years, kid 'graduated' but I have been held back apparently :) I have given invited presentations at the state level on how the school implements IT, as well as statewide in-service presentations. Since the rep's were my neighbors, I thought I as 'tight' with them, but ... que sera. We already provide all in-school software to the kids at no charge except for the Type-to-learn package which is about $10. I will keep on trying via the legislature, only problem to resolve is how much time is left in a day after the regular job, etc. Seems this is going to take awhile. Still wish there was some legal issue that could be brought up, but it appears that there isn't. Thanks for the suggestions. I will keep on keeping on and see what happens.

TuxMath is pretty similar. I think it would be fun (and cheap and quiet) to build a classroom/lab server out of a mac mini or equivalent small form factor box. The 2 gig RAM limit would probably be the limiting factor for how many clients you could handle (it does have a Gig ethernet port) especially if you have a separate file server for the home directories. Has anyone tried it? If the next version has a core2 duo instead of the current core duo processor it would be even better. -- Les Mikesell les at futuresource.com From dyoung at mesd.k12.or.us Thu Mar 15 17:55:25 2007 From: dyoung at mesd.k12.or.us (Dan Young) Date: Thu, 15 Mar 2007 10:55:25 -0700 Subject: [K12OSN] DST Changes?

I installed the tzdata package, and the zdump command shown below worked, but the date still didn't show right after the DST switch over on sunday. I found the problem was the /etc/localtime On some systems its a file that contains timezone info. On other systems it's a symlink to a file (in my case /usr/share/zoneinfo/EST5EDT). when you run a command that gets the current time, like the 'date' command, it looks at /etc/localtime. if that file or link isn't correct, it'll still report the wrong time. So, either you need to re-point that symlink at the correct zoneinfo file, or you need to copy the correct zoneinfo file on top of it. save a copy of the original file tho. And, there should be no problem doing this while the system is running. Jim McQuillan jam at Ltsp.org Shawn Powers wrote: > I thought my servers were all OK -- but I missed one.

I don't have any good advice really other than this. You posted this issue to this list a few hours ago. Most likely everyone on this list hasn't read your post. Also very likely most of the users that did read your post are not legal experts (I hope this broad statement doesn't offend anyone, just trying to make a point). So don't give up yet on the thought that there is no legal consequences to their decision just because the select few people who actually read this post in the last few hours didn't have any solid legal advice. Crazy thought here, ask this question at a local law college. I'll bet some law hungry student or professor could go a long way in your quest.

It gets as far as sabayon (the last user and last group) then hangs for a few minutes before exiting without showing ldap users. Is this serious? How can I fix it? I can add a group. # smbldap-groupadd -g 528 newentrant but it takes a long time to execute the command. It hangs for several minutes. I thought ncsd might have something to do with it so I turned off. It made no difference. I can smbldap-usermod -G to add a user to an existing group. This is quick. So is usershow and groupshow. When I tried to add a user using useradd-bulk I got this error. /usr/sbin/smbldap-useradd: unknown group 525 The errors were encountered during processing: smbldap-useradd error for sample: 1536.

I have a virtual WinXP & Win2K machines (using VMWare Server at home and VMPlayer on laptop) when I really need to use IE. There is a zero cost way to use XP as an RDP server (beyond the console), so hypothetically you could run a virtual XP machine and use rdesktop to access it and run IE from there without a Windows Server license, or TS CALs. I don't have the XP conversion info at hand, so please use google. I saw the info from a link supplied on either this list or the LTSP discussion list, so the archives should have it too. > David Hopkins wrote: > > All, > > > > This is off-topic, but apparently the DOE for Delaware is developing > > software (paying for the development) which will require the use of IE > > in order to be used.

Very, very old distos used a symlink for /etc/localtime so all you had to do was replace the data files. Then some versions used a copy on the theory that the targets on /usr might not be mounted when some programs start but they forgot to fix it on updates. Current versions replace the copy when the tzdata rpm is updated. The way to check what it will say in the future is with a command like: date -d "March 11" date -d "March 12" and note the standard/daylight time on the output. -- Les Mikesell les at futuresource.com From GLessard at cegepoutaouais.qc.ca Thu Mar 15 19:30:17 2007 From: GLessard at cegepoutaouais.qc.ca (Guy-Michel Lessard) Date: Thu, 15 Mar 2007 15:30:17 -0400 Subject: =?ISO-8859-1?Q?R=E9p.=20:=20Re:=20[K12OSN]=20DST=20Changes=3F?= In-Reply-To: <45F989E2.7090703@McQuil.com> References: <20070223182019.M63924@winonacotter.org> <45DF37EE.5090907@maltzen.net> <66C231AE-0AE6-4222-9164-97271A30A952@inlandlakes.org><66C231AE-0AE6-4222-9164-97271A30A952@inlandlakes.org> <45F989E2.7090703@McQuil.com> Message-ID: <45F96689020000BB0000320F@wise.cegepoutaouais.qc.ca> When you say zone info file, do you mean tzdata?

(even though charter schools are public schools) which is why I can't get too aggressive (again, only a parent volunteer and don't want to jeopardize anything that the school is doing. we open a k-4 extension this fall with full day kindergarten which will make the school k-8). The example from David Trask about Maine makes a very nice option since it shows a proper re-evaluation and subsequent implementation. (Thanks David for the info) The DOE already bills us for A/V per 'computer' in the school. Last year we deliberately did not count any thin clients which upset them because it means the student/computer ratio for our school looks very low to them. I have the Win2k3 boxes and TSCALS already. Still, very good idea to price out and see if the implementation will require upgrades not only for our school but other schools as well.

I would have though NFS would be fastest, but after Googling a bit I'm not so sure. I can say that in my experience copying files from Linux to Windows via Samba is far slower than Linux to Linux via NFS, but Linux to Linux via SMB (CIFS) is apparently a different matter. You could try both ways at the same time, and run some benchmarks, then share the results with use (you can share the same files via SMB and NFS, after all). One caveat - apparently some recent Linux kernels have had problems with CIFS-mounted shares. I discovered this from researching after the _second_ system hang on my mom's linux box just after unmounting a Windows share. So by all means try it out, but don't be surprised if SMB gives you an unpleasant surprise.

On the intro screen (the browser window), on of the sentences ends like this . (a space and then a period). Another comment, which pertains not only to your live cd, but to most distros I've tried, is that the distinction between "games" and "education" or "edutainment" is very blurry. Some things that I think should be classified as education are in the games menu, and vice versa. Does anyone think this needs more attention in the K12LTSP distro and/or the live cd?

I'm afraid I tend to know my way around the config files more than the GUI, but if you sign in as root, you should be able to get to a Mime type dialog, where you can configure that. You may have to do it both for the browser and for the OS in general. Of course, that will just obfuscate things, rather than prevent Wine's use, but it should be obfuscated enough to prevent most kids from giving it a go.

Not really a file sharing method maybe, but I you want to transfer a large file over a network connection really fast, I'd just pipe it through netcat [0].

In our case the BladeSystem solution is comparable in price to the standard HP server equivalents. As Gavin suggests it is our intention to move towards blades as and when servers need to be replaced.

The catch is that it must get through the sheilding of the PPC case, and of the drive itself. That means that it has to be an extremely powerful magnet. It also helps greatly if the magnets field is tuned to better do that job, kind of like you have with some of the magnetic door barriers that are designed to wipe any media going out of a secured environment. Now, again, while its possible to do, its really hard. Even if you open a HD case itself and get the magnet spinning and very close to the platters, your still going to need and industrial power electromagnet to do it. I remember back in the 386 days a product that looked like a standard floppy, but when put in a drive and spun up, emitted a VERY powerful magnetic field which would unrecoverable wipe any hard drive in the case. I think they still make them. As to leaving the drive formatted, no way. A magnet would wipe those bits just as quickly as it would wipe data bits. A magnet does not have the kind of control over what it wipes to do this (at least not without all of those control circuits). _____ Steven Santos Director, Simply Circus, Inc.

After you open the HD case (not on a drive you're concerned about), check out the arm, there's a very powerful set of magnets *in* the case. I don't see how a set of magnets that close to a hard drive would do no damage, but a student using a magnet *could* damage it. >... > As to leaving the drive formatted, no way.

I would think the magnet would just randomize the bits and make it totally unusable until you did a format.

When I drop the icon on it I just get the message "Drag-and-drop a file......" basically the same message I get when I double click the icon. Can Computer not be removed from the Gnome Desktop? And I have 2 icons that are actually links to other folders, one icon called "Drop" that links to /home/Drop and another called "Public" that links to /home/Public. I drop them on the "Push icons to all user's desktops" and nothing happens. Can links not be pushed? help!

Here's what worked for me (with Eric's help, thanks Eric!) Download the k12ltsp-release and fedora-release packages for your system. yum update k12ltsp-release-6.0.0-2.noarch.rpm fedora-release-6-4.noarch.rpm Then "yum clean all" and "yum update" (1+ gig and it may take some time...) I had a dependency problems with the version of cups I was running so I had to revert to the older package before yum would update. I downloaded the cups packages from ftp://k12linux.mesd.k12.or.us and did a: rpm -Uvh --oldpackage cups* to install the older packages and then ran yum update again and it all worked. One more thing is the kernel. With fc6 you don't have to use kernel-smp and can just use the normal kernel package (which will detect multiple cpus). Your update will miss this and leave a fc5 kernel-smp on. Simply "yum install kernel" and you'll get the latest fc6 kernel and once you're up and running with that, rpm -e kernel-smp to remove the fc5 kernel and you're done. ;-) Paul From jim at winonacotter.org Fri Mar 16 18:32:34 2007 From: jim at winonacotter.org (Jim Kronebusch) Date: Fri, 16 Mar 2007 12:32:34 -0600 Subject: [K12OSN] OT: hard drives and magnets In-Reply-To: References: Message-ID: <20070316182519.M9330@winonacotter.org> > The kid claims they may have put a magnet near the computer.

Sounds like a lame excuse I may have come up with in high school :-) I killed a lot of things messing around and made crap up of how it "actually" happened. As for a standard home magnet (probably one from the fridge that hardly holds up their homework) wiping out an entire hard drive and nicely placing an NTFS or FAT32 file system back on it.....yeah right! Why do we even have format utilities, let's all quit messing around and just carry a fridge magnet in our pockets. Just make sure it is a 1" cube magnet and label all of the sides like so: "This side down for FAT32", "This side down for NTFS", "This side down for ext3".....etc. Tell this kid to start marketing his magic magnet, it would save us foolish tech guys a lot of time not having to run these silly utilities any more. He could be rich! Come up with your own lame proof and tell them you successfully recovered bits from the drive that told you he formatted the drive trying to re-install Windows with a restore CD from their home computer and hosed it up. Then let them know you did this with D cell battery while hopping on one foot.

But I absolutely need to be sure I have local device support. Jim if nobody responds to this, then post it on the LTSP list. Unfortunately I don't know how to do this, so I can't help. Eric H. was the person who first built Xvnc into the LBE and he then sent patches upstream to LTSP. Part of the benefit of LTSP 5 will be any package in the distro should work in the ltsp tree.

In this first attempt, I was shooting mostly to replicate what is in K12LTSP by adding whatever was missing from Edubuntu and removing anything that wasn't in K12LTSP. If Edubuntu already had the app, I didn't worry too much about whether it was under Edutainment or Games.

Message-ID: I would like some advice on options for optimizing overall LTSP performance. In particular I am looking at the importance of /home performance. I've described everything below. I start general and get more detailed as I go down. Key Questions: How can I improve performance in the most cost efficient way? Cost efficient not only in dollars spent on hardware but also in time required to maintain the system. Where is the bottleneck? Speed of /home drive or ltsp server load (CPU and RAM)? RAID 1, 10 or 5? I heard 5 has slow seek times. Is that important for /home on ltsp? Will RAID 10 give me much performance improvement over RAID 1? PCI or PCIe ? If seek time is more important that throughput, does it matter if I use a PCI card or a PCIe card? SITUATION I am looking to set up a /home server using SATA RAID. I currently have 2 AMD Athlon 2500XPs with 2GB RAM and 120GB SATA HDs. I also have an AMD Duron 1.2 with ATA HDs. The Athlons have PCI 2.2 66MHz bus. Not sure about the Duron (33 or 66MHz) Options I am considering: 1. Run the Athlon machines in parallel as LTSP servers and get an SATA RAID card for the Duron to run /home from. Duron would be ldap PDC, Athlons would be ldap BDCs. Advantages: Minimal expense /home and authentication load taken away from ltsp servers. 2. Run the Athlons in parallel and let one host /home in a raid 1 arrangement? With the other one running BackupPC (with backups to its own HD). Ldap set up in failover arrangement. Advantage: Cheapest option, only 2 virtually identical machines to maintain. Disadvantage:/home speed not maximized 3. Same as 2 above but install SATA RAID card for /home in one machine. Advantage: /home might be faster on separate channel (but probably limited by 66MHz bus) Disadvantage: /home load still on ltsp server. 4. Run one Athlon as the ltsp server and the other as the /home server. Ldap set up in failover arrangement. Advantage: /home speed should be faster Disadvantage: LTSP redundancy and load-bearing features lost. Less RAM for LTSP and probably too much for /home machine. 5. Use the Duron just for BackupPC and maybe Winxp in Vmware Advantage: More secure backup. Takes BackupPC load away from LTSP servers. Disadvantage: Slower processor of Duron may affect BackupPC performance. Another machine to maintain for little performance gain. BACKGROUND Environment: Primary school (Ages 5-13years old) Roll: <100 students Number of terminals: Total 26 24 terminals in classrooms (divided into 4 classes ? used at various intervals throughout the day.) 1 in the library (rarely used) 1 used for administration (constantly used) Other computers: 5 Windows laptops (occasional access to shared files on /home) Typical usage: Gnome desktop Junior Class (5 computers): GCompris, TuxPaint, Online Flash games Other Classes: Online Flash games, OpenOffice.org, Scribus (occasionally) Office: MSExcel, MSWord, MSAccess, MYOB (all under Crossover Linux) Firefox, Rhythmbox, TerminalServer Client Current server setup: Standalone Firewall and Internet filter (IPCop) K12LTSP-6 plus a few extra services: BackupPC (backs up to its own hard drive in the K12LTSP box.)

It was hard, because every time I rebooted I had to wait for so long. I took advice from another email how to shorten the boot time by editing the ldap.conf file. Adding these lines so if it can't find what it is looking for it just drops out straight away without waiting too long. timelimit 5 bind_timelimit 5 bind_policy soft I tried reinstalling, reconfiguring etc numerous times without much luck. But finally after init 1 then init 5 one last time suddenly ldap started working. I think the key things to look out for are: 1. You need to init 1 (or reboot) to get the client connected. 2. The only change I made to the configuration made by the install script was to uncomment out host 127.0.0.1 192.168.0.253 (my server IP address) in /etc/ldap.conf (and maybe /etc/openldap/ldap.conf) I can't think of anything else that I did.

No, its not physically possible. Any magnet strong enough to effect the drive through the case and through the drive housing would wipe everything it touches.

I put the snd-sis7019.ko file in /opt/ltsp/i386/lib/modules/2.6.17.3-ltsp-1/kernel/sound/pci but when I boot the 2300 I get an error that it couldn't find the modules snd_sis7019; notice the underscore instead of the dash.

Since both 5 & 6 are LTSP 4.2 based, I suspect I'll get a similar result with the ver. 6 server. Yes, the file has 755 permissions. I am using esd. I also have Gideon Romm's oss-alsa package installed; I need that to support some Dell laptops with maestro3 chips. I tried running 'insmod snd-sis7019' in the shell on the terminal, but it says it can't find any such module; it says the same thing if I try to load the maestro3 via insmod, so that may not actually reveal anything. If I try 'modprobe snd-sis7019' I get the same "module snd_sis7019 error", whereas "modprobe maestro3" does nothing, no error, but that's expected. I think the rc.sound script calls modprobe.

It says, "Read paragraph 1.4; it is about the (unlimited) number of Remote Desktop Sessions." excerpt in question: When you are using Remote Assistance or NetMeeting (or other software which provides similar functionality for a similar purpose) you may share a Session with other users without any limit on the number of Device connections and without acquiring additional licenses for the Software. To me this is completely different than what Xpunlimited provides and they're reading what the want to read. Am i right? It's multiple Sessions of Remote Desktop not a broadcast of one Session.

In-Reply-To: References: Message-ID: <1127.24.2.210.202.1174153933.squirrel@webmail.eastgranby.k12.ct.us> East Granby, CT has three school buildings. The HS/MS building is fiber connected to the Internet (via the Connecticut Education Network) at 10mbps. The two elementary schools are connected via Cox Cable service at 6 mbps. When I update servers at the HS (7 servers running Fedora 5), the download speed is very slow (about 8 KBPS per display tick). For example, I am now updating the kernel-smp and the download is indicating it will take 62 minutes. Yet at both elementary schools, the downloads speed. At one of the elementary schools with Cox Cable, I just updated a kernel in less than a couple of minutes. This has been consistent for over a year - most likely dating back to when we switched the HS from Cox to the CEN for Internet access. For all applications other than yum, downloading to the HS moves very quickly. One other symptom. When updating the repository metadata at the start of yum, the ones marked k12ltsp and webmin seem to also take a long time versus the other repositories. Any ideas as to why the downloads from yum are so slow at the HS?

But then right after that is when I get all the alsa errors. I'm using Gideon's oss-alsa sound package, which replaces the default sound package, because I need it to make sound work for some Dell laptops. But the fact that the 7019 driver works with the old sound package makes me hopeful that I can fix it by somehow incorporating the driver into the package. I think there may be some licensing issues--SiS won't say what the licensing is--that prevent the driver from being shipped with LTSP and perhaps Gideon's package has the same issue. But that doesn't prevent me from installing it myself if I can figure out how. I'll keep at it.

Say it is listed as " oss-alsa " . Do a ' rmmod oss-alsa ' at the server. Do a lsmod to make sure it is NOT showing now. Now boot up your little 2300 box. See if sound appears. if it does you'll know that is actually the culprit. I'm guessing when you reboot the server that module will be back. If it does not reslove anything just do a " insmod oss-alsa ' to refurbish it into the server kernel again. You should have sound back on your other cleints as before( I Hope),,,:) I would guess the oss-alsa install has probably hijacked some other perms etc as well? Its worth a shot. I would guess there are other underlying residue somewere,,though.

You should be able to get a 1000BT GBIC for the uplink from the server to your 3500 which will work fine but it wouldn't surprise me if you could find a whole switch of some other brand for what it will cost. Switches are pretty much commodity items unless you need some of the new voice QOS functions, especially if these will be isolated on the 2nd NIC of the server. -- Les Mikesell les at futuresource.com From microman at cmosnetworks.com Mon Mar 19 16:51:24 2007 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Mon, 19 Mar 2007 12:51:24 -0400 Subject: [K12OSN] Recommendation Needed In-Reply-To: <45FEC8CE.9050404@scheie.homedns.org> References: <45FEC8CE.9050404@scheie.homedns.org> Message-ID: <45FEBF8C.1040402@cmosnetworks.com> The only caveat I can think of with the $95 unit is whether or not Pete needs something that can do VLANs.

So, that should be doable. Also, Chuck Liebow mentioned...something, can't recall quite what, where we might find the vnc pieces for PPC. But neither he nor I have looked into it specifically. vncreflector *is* available for PPC: see http://rpmfind.net/linux/rpm2html/search.php?query=vnc-reflector But thinking about it now, what we really need is xvnc running on the client, correct? The vncreflector part just runs on the server, right?

What am I missing? What people are generally recommending is a switch with a gig uplink and 100M to the clients, but even with 100M on all ports there is a big difference. With TCP traffic, the receiver has to acknowledge the data at least within the transmit window size or the sender will wait. So for about every 3 packets or less that the server sends, an ack must come back from a client.

Okay, here is a link that looks like it would take advantage of what you describe: https://help.ubuntu.com/community/UbuntuLTSP/LTSPCrossArchSetup However this appears to be for LTSP version 5 and not 4.2....anyone know if this is correct? I have an Edubuntu server that I am testing, I may give this a try tomorrow and see if it works, and if so how well. But I am guessing for 4.2 Xvnc and Local Devices would need to be manually compiled in the LBE.

The screen looks a little funny while booting and then flashes to a red color before loading the login screen. Once at the login screen everything looks perfect. Maybe we can get this included in the /opt/ltsp/ppc/etc tree named XF86Config-4.desklamp or something. Then the default configuration will boot Bondi Blue iMacs, the XF86Config-4.indigo will boot indigo iMacs, and the XF86Config-4.desklamp will boot the desklamp iMacs. In order to get this file I just booted the iMac from the newest Ubuntu PPC liveCD and stole the /etc/X11/xorg.conf it created. No modifications and it works perfectly. So anyone who needs to create a config for another flavor iMac, give the Ubuntu LiveCD a try. Hope this helps someone. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean. -------------- next part -------------- A non-text attachment was scrubbed...

The only thing running on them is an X session for the screen and keyboard. The window manager/desktop and all applications run on the server, sharing the fast server CPU and file system. You aren't just booting from the server - everything runs there. -- Les Mikesell lesmikesell at gmail.com From vince at totalsense.com Tue Mar 20 22:44:41 2007 From: vince at totalsense.com (Vince Callaway) Date: Tue, 20 Mar 2007 15:44:41 -0700 Subject: [K12OSN] Speaking of Macs In-Reply-To: <46000A2B.81D5.0081.0@mceschools.com> References: <1174417789.19036.2.camel@dbserver> <46000A2B.81D5.0081.0@mceschools.com> Message-ID: <1174430681.19036.13.camel@dbserver> On Tue, 2007-03-20 at 16:19 -0500, Joe Korzeniewski wrote: > In regular macs, you can boot to open firmware by holding command+option+o+f during boot and typing boot enet:192.168.0.254 I'm a complete mac noob.

Did you try turning off selinux? That has caused problems in the past. As for the users having access to the full file system on the server, that is the way it's supposed to work; it is not a chrooted environment that the users log into. A kernel and an X server are loaded on the client, but then pointed at the display manager, gdm by default, on the server via xdmcp. So, users are logging into the server similar to if they were telnetting or ssh-ing in, except with a graphical interface. Once logged in, users are 'on' the server.

It has every time for me. I even migrated a couple of fedora boxes to K12LTSP by adding the repository and loading the packages. No issues. The concept of thin client is actually an old one. Companies like NCD, Neoware, WYSE and others have built self booting computers that do nothing but connect to an xwindows session and log in. The server actually runs the application and each user appears as a login on the server. So they would have full filesystem access. It is not an issue under linux. The advantage of this setup is the client computer handles the graphics processing. The clients CPU architecture is also unimportant. So long as a compatible windowing session is running. That is why we can have macs act as thin clients on an intel based linux server. The other advantage is the client only needs enough processing power and ram to handle graphics and a small bootloader. I just bought two used neoware boxes off ebay for $10 each. These old thin clients still operate fine for ltsp even though these were 300mhz cpus.

Once the terminal can see the server, all the programs run on the server and display on the terminal. So it is normal for the terminals to have full access to the server's file system. Note that this is not insecure, because you still have all the Linux file system permissions keeping regular users out of the stuff that they shouldn't have access to. This is by default, and you don't need to change any permissions in order to acheive this. Regular users can see some, but not all system files, and they can't modify any of them. -Rob On Tue, Mar 20, 2007 at 04:07:11PM -0700, xmechanic wrote: > > > > > > > > Hi,

Currently what others in your situation are doing is running FreeNX on one server and connecting to it from the other server. So you launch two instances of fl-teachertool in separate windows.

So, unless you put some mechanism in the user's `/.lpoptions that detects which client machine is being used, the .lpoptions route won't do you any good; it will only work for one location. The script above looks at what client machine is being used, and then sets lpoptions based on that.

You need the X11 package. It's on your OSX Tiger dvd. Insert it and select "Optional installs". Select it, install it and run X11 applications, such as No Machine Client, OpenOffice.org, Gimp and others.

If all users booted from the same boot server, but pulled apps from different app servers, would TeacherTool still pick up all users and all processes? I am guessing that TeacherTool only picks up processes show as running on the server it is running from? How does TeacherTool find users and processes? Say you had 3 servers in your load balance cluster. Could an ssh tunnel be setup in all directions from server to server so that no matter which server you ran your teacher tool from you could get a list of logged in users and running apps from another server? Just thinking that maybe if the processes that are probed by TeacherTool can be tunneled over ssh maybe it could all be tied together. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

After a quick google search I found this page which indicates that rdesktop should be able to mimic all features of a windows rdp client.

Those are "OldWorld" machines that need something like BootX to boot Linux (yaboot won't work). Yellow Dog Linux used to have BootX up to at least the v3.0 series. Your clone likely is an OldWorld machine. My suggestion would be to grab an older version of Yellow Dog Linux, do a minimal installation of it on this clone box (the bare basics + X11 is all you need--i. e. no GNOME, no KDE, none of that stuff). Then tell X11 to do a XDMCP query at boot time (you can do that in /etc/rc.d/rc.local). This is how I did it on a Sun Ultra 5 box with Red Hat Linux 6.2, as well as with a Power Mac 5500 with YDL 2.3. Note that you probably will need at least 32MB DRAM for this to work at all. YDL on the Power Mac 5500 didn't like it too well when I had less than 32MB DRAM in there, swap partition or no. If it's a NuBus device, then you're in for some real work. Like Chuck, I too have done it with NuBus 5200's. Once you figure out how to do it, it's not that hard. But that first time figuring out the details to make it actually work is a pain. --TP -------------- next part -------------- An HTML attachment was scrubbed...

Correct. > > How does TeacherTool find users and processes? Say you had 3 servers in your load I use this line to find user id's and ip's netstat -t -e -n|grep :6000| grep ESTABLISHED |sed -e 's/:/ /g'| sed -e 's/ESTABLISHED/ESTABLISHED /' | awk '{print $9,$6}'|sort|uniq The last sed is for the difference in the way Debian and Fedora netstat output is displayed. BTW if you are using a system that is not using english you have to modify the above line since the word ESTABLISHED will appear in a different language. I will try to fix this in my next version. Someone suggested I use LANG=C netstat... Once I have all uid's which I can then change into usernames. I collect processes in a loop for each user like this ps --User username -o pid,rss,comm --sort -rss > balance cluster. Could an ssh tunnel be setup in all directions from server to server > so that no matter which server you ran your teacher tool from you could get a list of > logged in users and running apps from another server? It's possible to do that. You would have to setup root ssh-keys without a passphrase. But some things would break. Big problem would be broadcasting, which is the best feature of fl-tt (in my opinion). You can only run one session of vncreflector (which server?). Pick one. Now I have to ssh into the other server launch vncviewer for each user that connects to an ip OUTSIDE the lan of that server. So in addition to setting up fl-tt, which people sometimes have trouble with you're going to have firewall issues since vncviewer has to get through BOTH server firewalls. Not to mention the huge ip traffic that's going to get created through eth1 and one of the NAT servers. I guess what I'm saying is I'm not sure if it's worth doing if there are not that many people using load balancinng. And anyone who is, is probably not using more than 2 servers. So by using FreeNX you can have a quick fix. That said, if anyone is willing to hack on my code I would be willing to provide some guidance. The new feature I'm going to concentrate on now is the vncsnapshot window. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From mparic at compbizsolutions.com Wed Mar 21 16:16:35 2007 From: mparic at compbizsolutions.com (Michael) Date: Wed, 21 Mar 2007 09:16:35 -0700 Subject: [K12OSN] LTSP Audio In-Reply-To: <20070321144405.732C8731D2@hormel.redhat.com> References: <20070321144405.732C8731D2@hormel.redhat.com> Message-ID: <990FDFE0-A427-4BF4-AF89-16300F586536@compbizsolutions.com> Dave, Thanks for the reply; I will double-check the configuration based on the wiki page.

If you solve the screen hogging issue, please let me know! I think I actually solved it at last years NCLS, but I don't remember for sure. If it pops into my head I'll post back out to a new thread. If I remember right it actually is on screen 02 when it fires up it just so happens that it is the first session available so it is displayed. I think there was a switch or something to either delay the login of rdesktop so that the LTSP login won the race, or a switch to set screen 01 as the default to be shown. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

To make it simpler for the students and more secure for the school, I created an Application Launcher desktop icon that starts rdesktop and runs just the program (no Windows desktop). For security reasons I have the students enter their username and password to access the Windows server (it's the same as their Linux log in as it's stored in an LDAP directory). When they close the Windows program they are automatically logged out of the Windows server and rdesktop. Sound works great as long as sound is working on the thin clients (see my other posts for issues I'm running into with KDE). Here's the command line I use for the launcher: esddsp rdesktop -r sound:local -d DomainName -f -s "C:\PathToProgram" ServerIPAddress The -r switch redirects the sound to the thin client, the -d is your Samba/Windows Domain Name, -f forces full-screen, -s starts the specified program and I connect to the Windows server via IP address as it's the most consistent. > ------------------------------ > > Message: 21 > Date: Wed, 21 Mar 2007 07:12:05 -0700 > From: "Ernie Hudson" > Subject: [K12OSN] rdesktop > To: "'K12osn'" > Message-ID: > Content-Type: text/plain; charset="us-ascii" > > Is it possible to run rdesktop from the linux log on and have sound > work > from a widows terminal server?

It has been a big help here at our school. We are currently in the planning stages of rolling out 200 thin clients for next school year. This will involve 3 servers - 2 K12LTSP and one File/Print/E-mail/Authentication server in addition to the existing K12LSTP server.. So I'm just doing some thinking about the time schedule for the roll out and when I will build the servers. I'd like the servers built and ready by the end of this school year so that I can concentrate on the thin clients during the summer, but I'm weighing that against using K12LSTP 7. -- Mel Wade "The real problem is not whether machines think but whether men do." - BF Skinner http://www.melwade.com -------------- next part -------------- An HTML attachment was scrubbed...

The /opt/ltsp/i386 directory contains code that executes on the client. It is a basic bootloader and video driver. You can think of the login as a multi-threaded telnet session. The other shares in your /etc/exports file are for files common to all clients. Things like fonts etc.. You can have a client that boots off it's own hard drive to bring up the graphical interface without using LTSP. That is how it has been done for years. No exports are required. Believe it or not this is actually a slower process.

No, you can't chroot and still execute programs you can't access. Is there some reason you want a chroot environment?

The way our school is setup the students login to the terminals with the terminal's name (library1) as their login/passwd. So, each of the 12 library computers is labeled as library1-12 and the lab is labeled as station1-15. So, if this is the case I could do the /home/username/.loptions and add in the default printer. Do you know if I can just use the /etc/cups/lpoptions file and modify it for each user's /home/username/.loptions?

Mel, if I were you, I'd hold out for the K12LTSP 5.0EL version. The reason for that is logistical. Remember that Fedora Legacy is no more, so if you want security fixes, you *have* to reinstall your OS every year. By contrast, I've been running K12LTSP 4.2EL for two years and have not had to reinstall my operating system. All I have to do is "yum update", and I'm done. This is trivially scriptable if you've got multiple servers. With the exception of sound on the new Flash 9, the server has been trouble-free. Additionally, it keeps a consistent user interface for your users. The kids aren't going to care much, but the *adults*, i. e. the ones who actually have the authority to stop you, tend to freak out at changes. I've used Fedora-based K12LTSP for demos, and it's great for that. But my guys and I also have experienced some stability issues with Fedora on our desktops (we now run CentOS, Ubuntu Dapper Drake, or Slackware for that reason). Fedora is, by its nature, bleeding edge, and I prefer not to present my users with a perpetual-beta system that I've seen act flaky at times (FC2, FC5, and FC6 in particular). Others, obviously, differ on this point, some of them greatly. --TP From mel at melwade.com Wed Mar 21 18:16:01 2007 From: mel at melwade.com (Mel Wade) Date: Wed, 21 Mar 2007 11:16:01 -0700 Subject: [K12OSN] K12LSTP 7 In-Reply-To: <460175A5.1070604@cmosnetworks.com> References: <43080f460703210959m326b7a52h9691d02ca8a01518@mail.gmail.com> <4601693C.5030300@mail.mesd.k12.or.us> <43080f460703211033h230e0ea7p28ebfc8691b1bc1e@mail.gmail.com> <460175A5.1070604@cmosnetworks.com> Message-ID: <43080f460703211116t3ab39f31s813fa471cee5efef@mail.gmail.com> Where can I find form information on the 5.0EL version and what will be in it?

That's because K12LTSP 5.0EL doesn't exist yet. :-) It will basically be Red Hat Enterprise Linux 5.0, with all the LTSP and educational goodies that we've come to know and love added to it. Check out Red Hat's Web site for some of the cool new features. CentOS (http://www.centos.org) is a free-as-in-beer clone of the Free-as-in-Freedom Red Hat Enterprise Linux. Now that RHEL 5 has been officially released, CentOS 5 should be out pretty soon. --TP _______________________________ Do you GNU!?

The CentOS project has nothing to do with the K12LTSP project; K12LTSP just uses CentOS's software (as do many other projects). So, you won't see anything about K12LTSP on the CentOS site.

However, they are not using 100% LTSP. They use bits of ltsp to pxe boot their clients and mount / over nfs and they use NIS or LDAP for auth but they DO NOT use XDMCP or ssh to shoot the display over the network. Everything runs locally. Every new client is an AMD Sempron cpu with 512MB (easily powerful enough to run everything locally). The clients are almost the same price as many thin clients. About $250 CAD. They are actually using a modified Muekow ltsp implementation built in house inside a virtual private server http://linux-vserver.org/Welcome_to_Linux-VServer.org Kind of like a super chroot environ that requires a patched kernel. (Not a virtual machine like Xen or VMware) The clients are still diskless. But since everything runs locally there is no traditional problems associated with ltsp. Like having an entire classroom (30 clients) watch a full screen youtube video (flash). Or fullscreen quicktime/mpeg4 video (remember you are streaming [over nfs] the highly compressed video file in exchange for cpu power required to decompress it). Or have a Beryl 3D enabled student desktops. Or 30 kids playing GNU/Chess. Good luck doing these things with traditional thin client ltsp. I don't care if you have a dual Opteron, it's still going to fall to it's knees. The nfs server at Barriere Secondary serves the entire school: approx. 115 clients. Local devices like USB sticks: no problem, each client is running a full blown OS. No need for ltspfs. All clients run Xvnc so support for the district techs (who by the way are all highly qualified certified Linux/BSD gurus) is a snap since they can fix things remotely. LTSP 5 has this ability as it uses the distro packages instead of it's own and is much easier to implement local apps. In my mind, this is the future of ltsp. Kamloops is just ahead of the curve because they realized that if their initiative was to be successful they didn't want any of the limitations of ltsp while still having the advantages. Clients are diskless centrally managed appliances. Plug it in and it works, advantages that ltsp has always had. Some may say apps take longer to load over nfs. This may be true but if you configure your network properly you can address this. Gigabit switch backbone. Port trunking. Another solution I like, use multiple gigabit nics in your nfs server on different subnets connected to separate switches as described here. http://k12ltsp.org/mediawiki/index.php/Technical:Subnetting Thereby, creating dedicated bandwidth for different parts of a school and preventing bottlenecks. In any case, once an app is loaded it's fast and if you happen to shutdown the app (say Firefox) and start it again the machine does not take nearly as long to launch it again because apps are cached locally in the memory of the client machine (remember the 512MB). The only down side is power consumption as compared to real thin clients. However, having said this I know that most people running ltsp are using old hardware as thin clients which are not energy efficient. However, I believe the advantages outweigh this issue especially when you have to compare them to stand alone Windows labs. Having said this, those AMD Semprons are actaully a pretty efficient cpu. Part of the reason local apps have not gained as much momentum in ltsp circles is that the raison d'etre of ltsp was that you didn't have to purchase new clients. Simply re-deploy existing old boxes (As I and many others have done) as thin clients. So after a few years and ltsp was seen as a viable solution people kept the "Run it on the server" ideology. Even though the price difference between new real thin clients and relatively powerful diskless clients has almost disappeared. My last point, the nfs servers in Kamloops are actually hybrid servers. They actaully have scripts to determine how powerful a client is at boot time then decide how many apps (all or some) will run locally. So the nfs server is also a traditional ltsp server. This, I believe, is a stop gap measure until all their clients are replaced with new ones. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From daengbo at gmail.com Thu Mar 22 03:47:36 2007 From: daengbo at gmail.com (Daniel Bodanske) Date: Thu, 22 Mar 2007 12:47:36 +0900 Subject: [K12OSN] American Idol & K12LTSP In-Reply-To: <4601EF91.70908@elp.rr.com> References: <4601EF91.70908@elp.rr.com> Message-ID: IceWM is certainly an option if you disable the menu and just put an icon on the toolbar, but why even go that far?

You don't try "upgrading" Fedora to RHEL or CentOS without totally breaking your operating system. It's like trying to upgrade Windows 95 to Windows XP; you're looking at a total reinstall. Just want to make that clear so you don't blow up your OS unnecessarily. The upgrade path from RHEL/CentOS is from version 4.x to version 5. The upgrade path from Fedora is from version 5 to version 6. You could also go to version 7 when it comes out. Now, Fedora is on a totally different release schedule from RHEL/CentOS. A new version of RHEL/CentOS comes out approximately every two years, but each release is supported for bugfixes (but not typically any new features) for seven years. That means that you can reasonably get away with upgrading your servers every, say, four or five years (your users will want new features eventually). That means that my K12LTSP server running CentOS 4 (released in early 2005) will have bugfixes until the year 2012. Red Hat does say that it's possible to do an "upgrade" from one major release to the next one, but that it's not recommended. They (and most of us here) recommend a fresh install. The nice thing about a LTSP architecture is that you don't need to do this on the 30 workstations in your computer lab. You only need to touch one server. Fedora releases, by contrast, come every six to nine months. They are quite bleeding-edge. They are also supported with bugfixes and security updates for, on average, a little over a year. That means that you're upgrading approximately once a year. It is no more recommended to try to "upgrade" a Fedora release without reinstalling than it is RHEL/CentOS. A fresh install is best. It's more frequent than RHEL/CentOS, but it still beats installing Windows XP/Vista/Whatever on 30 boxes, Ghost or no. This is, BTW, why I *ALWAYS* keep /home on a separate partition. *ALWAYS*. This way, I can go from, say, Ubuntu Breezy Badger to, say, CentOS 4 or Slackware 11. Obviously, this scenario would require a fresh install. :-) But, since /home is on a separate partition, I can blow away Ubuntu Breezy totally, install CentOS/Slackware/Debian/Ubuntu Edgy/Whatever (remembering not to format /home!), and be back in business without losing any user data. In short, if you partition this way, you can relatively easily even hop distros when it's time to upgrade. --TP _______________________________ Do you GNU!?

Centos 5 will start out with approximately the application versions that are on FC6 which are good choices now. A couple of years from now you can expect the box to still be running reliably and still a good choice for server applications but desktop apps are still evolving rapidly and you may want to jump to some newer FC version to get new app version. I'd recommend going with the EL version when it is current so your next choice of when to upgrade will be based on what you want to run, not being forced to switch because your old version is not supported with updates any longer. It's also a good stable choice for a machine that will be a home directory server. -- Les Mikesell lesmikesell at gmail.com From vince at totalsense.com Thu Mar 22 05:33:16 2007 From: vince at totalsense.com (Vince Callaway) Date: Wed, 21 Mar 2007 22:33:16 -0700 Subject: [K12OSN] K12LSTP 7 In-Reply-To: <46020F36.1060306@cmosnetworks.com> References: <43080f460703211116t3ab39f31s813fa471cee5efef@mail.gmail.com> <403593359CA56C4CAE1F8F4F00DCFE7D07E1FEEB@MAILBE2.westat.com> <43080f460703211224hcdfcc4bjf78a2f763375c80c@mail.gmail.com> <46019733.5060003@scheie.homedns.org> <43080f460703211433kecf8c7dtc61a543f7b3b61e4@mail.gmail.com> <4601A5C0.3040905@mesd.k12.or.us> <43080f460703211720h5e7f7917yca2c1455461830aa@mail.gmail.com> <4601D7AD.5090505@futuresource.com> <43080f460703211812o12425fcdwac496d28630bb4ae@mail.gmail.com> <46020F36.1060306@cmosnetworks.com> Message-ID: <1174541596.16803.12.camel@dbserver> I was explaining the differences to some of my sons friends and came up with this analogy.

When they close the Windows program they are automatically logged out of the Windows server and rdesktop.

Here's the command line I use for the launcher: esddsp rdesktop -r sound:local -d DomainName -f -s "C:\PathToProgram" ServerIPAddress The -r switch redirects the sound to the thin client, the -d is your Samba/Windows Domain Name, -f forces full-screen, -s starts the specified program and I connect to the Windows server via IP address as it's the most consistent.

The differences between all Linux distributions boil down to the install and administrations methods and the choices of application versions that go into a particular distribution version. Once you are running everthing is mostly the same. Fedora/RHEL/Centos all grow out the RPM packaging style developed by Red Hat, with new app versions and major changes going through a few fedora revs before being incorporated into RHEL, then rebuilt as Centos. Fedora and Centos use yum as the higher level package manager and updater to deal with dependencies; RHEL uses up2date with subscription access. Ubuntu is built on the Debian disto base, using .deb packages with apt-get as the higher level manager. Debian has a long history and a lot of contributed packages but they are strictly non-commercial with an attitude of "when it's ready" for new releases so they often lag behind other distributions in what they call their 'stable' version. Ubuntu adds scheduled releases and some user-friendliness to their version but they are still fairly new. They haven't been through a 'big' upgrade (like changing the kernel from a 2.4 to a 2.6 version) yet so it is hard to compare how well things like that will go. -- Les Mikesell lesmikesell at gmail.com From microman at cmosnetworks.com Thu Mar 22 15:49:59 2007 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Thu, 22 Mar 2007 11:49:59 -0400 Subject: [K12OSN] K12LSTP 7 In-Reply-To: <4602A8E1.7070308@scheie.homedns.org> References: <43080f460703211116t3ab39f31s813fa471cee5efef@mail.gmail.com> <43080f460703211224hcdfcc4bjf78a2f763375c80c@mail.gmail.com> <46019733.5060003@scheie.homedns.org> <43080f460703211433kecf8c7dtc61a543f7b3b61e4@mail.gmail.com> <4601A5C0.3040905@mesd.k12.or.us> <43080f460703211720h5e7f7917yca2c1455461830aa@mail.gmail.com> <4601D7AD.5090505@futuresource.com> <43080f460703211812o12425fcdwac496d28630bb4ae@mail.gmail.com> <46020F36.1060306@cmosnetworks.com> <1174541596.16803.12.camel@dbserver> <43080f460703220748j7482d899i23f854cca1b720f4@mail.gmail.com> <4602A8E1.7070308@scheie.homedns.org> Message-ID: <4602A5A7.4070507@cmosnetworks.com> I'd agree on the "bleeding edge" stuff if referring to the K12LTSP "EL" releases. But the Fedora-based releases are at least as bleeding-edge as, say, Ubuntu Edgy. That said, the LTSP support in K12LTSP is a bit more mature; the files are actually in the standard upstream LTSP places (ltspadmin, for example), and K12LTSP supports Power Mac thin clients out of the box. Either of them will work for a "full-blown" LTSP environment. In production, I prefer the K12LTSP "EL" releases for the stability. That said, I'm still tracking Edubuntu and am currently playing around with the 6.10 "Edgy Eft" release now. Hopefully Feisty Fawn will be ready in time for my yearly "LTSP for Education" demo in June; if so, I'll try that. --TP _______________________________ Do you GNU!?

Message-ID: <4602BF3D.5000604@scheie.homedns.org> I want to use afpfs-ng (a new version was just released) to allow students to access their files on the district's "central storage server" which is a Mac server that will only talk over AFP, as decreed by the district techs. On the client desktops, we're using autologins, so my thought was to create a create a script that queries the user for an ID & PW, then passes those parameters to afpfs-ng to mount the user's personal directory from the Apple server, and then call Nautilus or some other file manager and point it at the mountpoint so students can get to their files. We'd put an icon on the desktop that calls the script. Here's the tricky part: I want the share to be unmounted when the file manager is shutdown. That way, all a student has to do is close the file manager window and the mount will go away, so another student can't come along afterward and mess with the previous student's files. The script would look something like this: get user ID & PW mount directory via afpfs-ng call Nautilus and point it at mountpoint wait until Nautilus is shut down, then unmount mountpoint The problem is this doesn't work with Nautilus because it's part of Gnome and so doesn't maintain a separate PID that I could monitor and use as a trigger for unmounting. I suppose I could call Konqueror, but that loads so much overhead that it takes a while to come up. I'd prefer to use Nautilus because it's the same, for the users, as when they open the local directories. Any ideas?

However, they are not using 100% LTSP. They use bits of ltsp to pxe boot their clients and mount / over nfs and they use NIS or LDAP for auth but they DO NOT use XDMCP or ssh to shoot the display over the network. Everything runs locally. Every new client is an AMD Sempron cpu with 512MB (easily powerful enough to run everything locally). The clients are almost the same price as many thin clients. About $250 CAD. They are actually using a modified Muekow ltsp implementation built in house inside a virtual private server http://linux-vserver.org/Welcome_to_Linux-VServer.org Kind of like a super chroot environ that requires a patched kernel. (Not a virtual machine like Xen or VMware) The clients are still diskless. But since everything runs locally there is no traditional problems associated with ltsp. Like having an entire classroom (30 clients) watch a full screen youtube video (flash). Or fullscreen quicktime/mpeg4 video (remember you are streaming [over nfs] the highly compressed video file in exchange for cpu power required to decompress it). Or have a Beryl 3D enabled student desktops. Or 30 kids playing GNU/Chess. Good luck doing these things with traditional thin client ltsp. I don't care if you have a dual Opteron, it's still going to fall to it's knees. The nfs server at Barriere Secondary serves the entire school: approx. 115 clients. Local devices like USB sticks: no problem, each client is running a full blown OS. No need for ltspfs. All clients run Xvnc so support for the district techs (who by the way are all highly qualified certified Linux/BSD gurus) is a snap since they can fix things remotely. LTSP 5 has this ability as it uses the distro packages instead of it's own and is much easier to implement local apps. In my mind, this is the future of ltsp. Kamloops is just ahead of the curve because they realized that if their initiative was to be successful they didn't want any of the limitations of ltsp while still having the advantages. Clients are diskless centrally managed appliances. Plug it in and it works, advantages that ltsp has always had. Some may say apps take longer to load over nfs. This may be true but if you configure your network properly you can address this. Gigabit switch backbone. Port trunking. Another solution I like, use multiple gigabit nics in your nfs server on different subnets connected to separate switches as described here. http://k12ltsp.org/mediawiki/index.php/Technical:Subnetting Thereby, creating dedicated bandwidth for different parts of a school and preventing bottlenecks. In any case, once an app is loaded it's fast and if you happen to shutdown the app (say Firefox) and start it again the machine does not take nearly as long to launch it again because apps are cached locally in the memory of the client machine (remember the 512MB). The only down side is power consumption as compared to real thin clients. However, having said this I know that most people running ltsp are using old hardware as thin clients which are not energy efficient. However, I believe the advantages outweigh this issue especially when you have to compare them to stand alone Windows labs. Having said this, those AMD Semprons are actaully a pretty efficient cpu. Part of the reason local apps have not gained as much momentum in ltsp circles is that the raison d'etre of ltsp was that you didn't have to purchase new clients. Simply re-deploy existing old boxes (As I and many others have done) as thin clients. So after a few years and ltsp was seen as a viable solution people kept the "Run it on the server" ideology. Even though the price difference between new real thin clients and relatively powerful diskless clients has almost disappeared. My last point, the nfs servers in Kamloops are actually hybrid servers. They actaully have scripts to determine how powerful a client is at boot time then decide how many apps (all or some) will run locally. So the nfs server is also a traditional ltsp server. This, I believe, is a stop gap measure until all their clients are replaced with new ones. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn For more info see -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

We use an in-house developed route management and logging web application but the administration of the trans dept wanted the drivers to be able to access ONLY that. I built the standard k12ltsp install, configured 4 terminals for autologin based on MAC address and set the user desktop to fluxbox. I edited the fluxbox menu to do exactly what you are requesting. Firefox auto-launches on login. If it is closed they can right-click the desktop and have two choices; relaunch FF or logout. Works for us.

You want the clients on the inside of the network to also have unique addresses on the outside adapter of the server. Is this correct? If so, then ifconfig would look like: eth0 ... etho:ws001 ... etho:ws002 ... etho:ws003 ... etho:ws004 ... Getting each user login to bind to a different outside adapter might be possible, but it would be easily broken, I'd guess, when something on the inside or outside network changed. Just my 2 cents.

In each of those you can specify the MAC address of the card you want the script to control. The syntax is HWADDR=00:08:54:4F:49:1D Adjust the above address to fit your cards, and use the respective address for each card. BTW, there's something wrong with your installation. I've installed K12LTSP 6 several times on various machines in the past few months, and I've never seen your problem of an empty /tftpboot. I'm not sure where to look but perhaps check through your installation process to make sure you're not choosing something odd along the way.

Try the following url on say your Linux terminals.See if they launch correctly? Then, try the same on your winders boxes,see if webstart demos work on them, then go to your AR web based thingy, see if this launches correctly on the winders boxes.This may tell you in fact if it is actually java webstart prob.

I think there are other downsides: * capital cost per seat is almost $100 more than a fanless thin client like NTAVO 6040 * there will be power supply and cpu fans wearing out and making noise * power consumption will likely be double or triple that of compact thin client * the network has to load 100 megabytes or so into each client at the start of classes as compared to a thin client loading only a few. Caching may help from a warm login but that means you have to leave the things running, increasing the energy consumption again. Still it is a neat solution if you are going to do lots of multimedia or heavy CPU load. I would only use it in a multimedia development lab. All of my classroom and lab experiences with the curriculums I have do not need it. I think most of the downsides would be mitigated with a slightly more powerful processor and Multi-seat X. Then, the power is averaged over 5-10 users. One upside not listed is that the server becomes a straight file server so it might be able to service more clients this way. I still think straight LTSP is the best solution in most cases. I could see one such client per classroom and possibly a bunch in a multimedia lab.

Caching may help from a warm login but that means you have to leave the things running, increasing the energy consumption again. They do have automated (cron) shutdown scripts as well as wakeup scripts (without security issues I might add). So no, they don't leave them on. However, the morning boot time is longer than regular ltsp but you can automate that to just before school starts. > Still it is a neat solution if you are going to do lots of multimedia or heavy CPU load. I would only use it in a multimedia development lab. All of my classroom and lab experiences with the curriculums I have do not need it. I think most of the downsides would be mitigated with a slightly more powerful processor and Multi-seat X. Then, the power is averaged over 5-10 users. I agree for using a browser, wordprocessing and most things thin clients are enough. So you're right it really shines in a multimedia situation. However, as time goes on web content is getting more and more multimedia rich. And it's nice to be able to handle that kind of bling.

Good point. > > I still think straight LTSP is the best solution in most cases. I could see one such client per classroom and possibly a bunch in a multimedia lab. I am a big advocate of ltsp so I can't really disagree. But I have to say seeing those fat diskless clients running an mplayer movie was a sight. I can't do that in my own lab. I'm just glad LTSP 5 is developing into a system where local apps are going to be much easier. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From rowens at ptd.net Sat Mar 24 13:29:43 2007 From: rowens at ptd.net (Rob Owens) Date: Sat, 24 Mar 2007 09:29:43 -0400 Subject: [K12OSN] Active Directory expiring passwords Message-ID: <20070324132943.GC14987@clubber.owens.net> Can Linux users be given a warning when their Active Directory password is about to expire?

This is v,,e,,r,,y simple to install. Follow the following link for info. The program is called ies4linux. It is basically a very small setup script that ends up installing version(s) 5.0 & 5.5 & 6.0 of Internet Explorer,and places icons on your desktop. It automagically pulls down all the service pack crud so all are up to date. it pulls down flash for each as well. The only prerequsite/dependecy required is that you have installed "cabextract" , a subset of wine. (there is an rpm available for cabextract.)From what the docs say you dont actually need wine installed? I m not sure about that though? I always install wine on all of our servers off the get-go. It asks a few questions,,then started pulling down all the cabs..and when done you have icons for each version on your desktop. I installed as root for example,then if you like just push out the version of whatever works best with your Ren Apps program. I dont beleive the script actually pulls down Shockwave,,and possibly this is what you are needing to run Ren Apps web. This may be an easy setup for your terminals to run Ren Apps web. http://www.tatanka.com.br/ies4linux/page/Main_Page Hope this helps.

Message-ID: <45209.192.168.254.3.1174851040.squirrel@www.eazylivin.net> hi vince, the best resource for now is to look at the wiki page that Jim M,posted. I bought a couple of the Neoware 5000's a couple years ago,for a little bit of nothing off of Ebay and they both pxe booted fine. They are decent for thin client use.Especially for testing for someone starting out. no fans etc either.The only downside to these are they only have 4mb of video ram,which when running java apps is very noticeable. Ther are fairly compact and simple and only one button, so they would be good for school use. ( less buttons less poking),,,:)Also the usb ports are not setup in ltsp/k12ltsp either as they are the geode prcessor,but possibly with some googling you can find a way to make the usb's work? I had to put an addon soundcard in them as well as the onboard sound you heard the processor "squeeking" through the audio jack? Hope this gives a little resource into this.

In my case I was trying to score a cheap workstation for a client. I paid about $50 for the two of them with shipping. I did a some searching because the one that works had a password on the CMOS setup. After some digging found it was factory set and is "DOGBITES" btw. I found it in the archives of this list. The message showed it in lower case, but it is actually upper case. The audio and usb is a non-issue. This workstation replaces an old wyse dumb terminal in a warehouse. The other box does not network boot. It does have a boot prom socket on the motherboard. The neoware software and ltsp don't seem to like each other. If I try to login I get a message about touchscreen not being supported. I don't have time to dig into it now, but I'm sure I can work around it. Some time in the next couple of days I will work up info on these two boxes. I now know what to look for to make sure I get one that pxe boots.

What I actually do in practice is just remove all the .gnome/ and related directories from ~/. I look at it this way: when you upgrade MS Windows, your desktop settings often get FUBAR'd, so you're better off with a fresh reinstall. Interestingly, I haven't run into this problem to nearly the same degree with KDE, which I also use a lot. Would this kind of scenario (upgrades and such) be a good case for the "EL" edition of K12LTSP? Thoughts? --TP _______________________________ Do you GNU!?

It's a commercial product from a commercial company. As such, there are restrictions on how it can be distributed--that is, you can only get it from Sun. There's no problem with YOU downloading it and using it on your system/server, but Sun doesn't allow anyone else to distribute it. Besides, as K12LTSP is a community effort, its software collection focuses on community-based projects. You have to think about 'free' in terms of speech, not price. > I think this is a GREAT resource, but the lack of documentation > available for a Windows savvy newbie is painful for me, not that I read > documentation, but when I get stuck, I like to have some reference to > fall on... > As mentioned, this is a community effort, meaning documentation is created by the users, including you now. ;-) There is the K12LTSP wiki at http://k12ltsp.org/mediawiki/index.php/Main_Page.

It IS possible to PXE boot the Dell gx110. But it's pretty well hidden. In the BIOS, under the 'Boot Sequence', it normally only shows three choices: CD, floppy, & hard drive. In the main BIOS screen, you must scroll down to 'Integrated Devices', and within that, you'll see, among others, 'Network Interface Controller', which is set to On by default. But this is not just a binary, on or off option; rather, it also contains the choice of 'On w/MBA'. Choose this, save the changes, reboot the box, go into the BIOS setup again, and now 'Boot Sequence' will list 'MBA UNDI(Bus1 Slot12)' which is the PXE boot option. Set that option to be the first choice, and voila! the box PXE boots. Hopefully, this info will be useful to someone.

Come and join us! Message-ID: Help us spread the word! Blog...repost...whatever! Go nuts! The post below has a noticeable "Northeast US" slant since that's where I originally posted, but I wanted you all to know....you're welcome. In the past we've had folks from FL, NC, VA, British Columbia, Quebec....and more....so feel free and welcome to join us this year! (I'm lazy....didn't want to type it all over) I also haven't mentioned much about the new conference at Gallaudet University in Washington, D.C., but wanted you all to know that this year we're hosting a new conference! The format will be similar to the others, but we'll have lots of new presenters and sessions! Being located in D.C. we're hoping to have quite a few well-known sponsors and project people with us as well. The planning is going very well and we hope to have the sessions pretty well set very soon. If you would like to be a presenter at the conference in D.C.....please contact Matt or I! moquist_AT_majen.net dtrask_AT_vcsvikings.org or copperdoggy_AT_gmail.com If you'd like to attend....even better! (August 5-8) When you get right down to it...the conference is an amazing experience for the money. ($485 for on-campus / $435 for off-campus....and this includes all meals, accomodations, etc and the conference!) For more info and to register (first read below)visit our web site at http://www.fossed.com Techies, admins, classroom teachers, students, consultants, vendors.....all welcome! We have something for everyone! Bring a team and learn together! http://www.fossed.com Register early! Previous post with the "Northeast slant" begins below: +++++++++++++++++++++++++++++++++ Hello everyone! It's that time of year again! Time to begin thinking about summer, upgrades, purchases, and enriching our minds with new knowledge! Once again, this year we're off to Bethel again for the annual conference at Gould Academy. Would you believe this will be our 5th anniversary! Five years! Wow! It all start with a ground swell from folks like you who wanted to know more about Linux/Open Source alternatives and how they could be applied to school networks and the classroom. Here we are 5 years later and still going strong! To celebrate, this year we're going to have some exciting new additions! Last year, the addition of the "teacher track" in which classroom teachers attended to learn more about using Open Source/Web 2.0/etc in their classrooms was so successful, we scrambled to add another teacher track for the UNH conference just 2 weeks later...and lo' and behold it was full! So...that kind of success merits some attention! This year we'll feature a full set of sessions for teachers! These will include, but are not limited to..."A Tour of Free Open Source Applications for your classroom...try them out!" (Bryant Patten, the man who actually wrote the book on this...seriously...he wrote a book...will be presenting), "Ok, I have Open Source in my classroom...now what?" (taught by one of our conference alumni who is an elementary classroom teacher), "Web 2.0, Blogging, etc. for your classroom" (taught by Sharon Betts and Kathy Malsbenden...popular session from last year...lots of new content for this year)..."Moodle: Designing Online Instruction for Digital Natives"..."Open Source applications on the MLTI laptops"...and much more! Lots of useful sessions to help you learn more without spending more! This year we'll be kicking the techie side of things up a notch! Last year we presented a 3-day programming track that was quite successful...especially at UNH...so we're bringing it back! Learn how to write simple programs and scripts that can make life a lot easier! Learn how to easily manage servers...deploy commands...make simple changes to MLTI laptops...and so much more! Have you ever wished, "If only I had a program that could so "such and such""? Well...learn some simple skills and you might just be able to write it yourself! We'll have a session entitled, "Beyond the GUI". We'll learn all about Linux firewalls, routers, and servers....in particular...the awesome IPCop server! For those of you deploying or hoping to deploy Linux/Open Source into the classroom...we'll be exploring the new kid on the block (and an AWESOME classroom operating system) Edubuntu. Edubuntu brings many new and exciting changes to the world of deploying Linux workstations and/or Linux thin-client terminals! We'll learn how to set up and deploy a Moodle server. And a new yet HUGE topic...Virtualization! Using VMware, Parallels, and so forth to easily deploy multiple servers on one piece of hardware...or to make easy to deploy virtual machines for use in the classroom! Imagine making a virtual Windows machine or Linux machine on one computer and then simply copying that file (yes...one file) to all the machines in the building and VOILA! You have deployed an entire operating system complete with applications! No more modifications necessary! Come learn more! Ok...so that's a taste of what we're offering...and we'd sure like to hear if there's something more you'd like to learn. It looks like a lot of sessions, and it is, but we'll have more half-day sessions this year so you can attend more sessions than in years past. Remember...Mac, Linux, Windows? We don't care! We're going to cover them all....we're talking about Open Source in our cross-platform world. Sure, we'll be spending quite a bit of time on Linux...especially on the techie side, but most of the sessions involving Open Source in the classroom will be essentially platform agnostic...so bring your Mac, Windows, or Linux machine (laptop) and we'll show you how you can have the same applications for everyone regardless of what kind of computer they use! Last, but not least is the atmosphere. You get a chance to relax, unwind, and enjoy learning about technology. We're a shorts and T-shirt kind of crowd. It's 3 days of hands-on learning. You get a chance to talk to other folks from other schools...share ideas...network...and more. The food is FANTASTIC! Seriously, you have to see it to believe it...ask anyone who's been. So what're you waiting for! Also...we'll be offering CEU's once again from USM. So if you are looking for some college-endorsed contact hours for recertification...this is a great way to get a whole bunch of them out of the way! The University of Southern Maine has been endorsing our conference work for a few years now and it's a great way to learn skills that you'll actually USE in your job. There's a small fee for processing the paperwork...and you'll get a certificate from USM to use for your certification. Once again at UNH this year we'll have the kids from the "Can-Do" project working on a development sprint. Last year it was amazing...they met with us (the classroom teachers) on Day One to gather ideas on how to make SchoolTool a better program...they took our ideas and made them a reality and showed us on the last day...it was so cool! So...where do you sign up? Visit us at http://www.fossed.com There are 3 conferences this year. The grandaddy of them all...at Gould Academy in Bethel Maine...June 19th - 22nd (arrive afternoon of the 19th to settle in a prepare for the next morning)....our second year at UNH in Durham, NH (subject to possible change of location in NH) July 8-11 (arrive the p.m. of the 8th), and our inaugural conference at Gallaudet University in Washington, D.C,(August 5-8...arrive p.m. of 5th)! Remember! ACTEM members can apply for $400 in professional development funds...it's a great deal and the conference will end up costing you a small amount in the end. Many folks have done this in the past and it's a great use of this ACTEM benefit! How much? The costs for Gallaudet and Gould are as follows: $485 - on-campus (all meals, rooms, etc. are included!) $435 - off-campus (only noon-time meal and snacks included) The UNH costs are not quite ready, but will be very soon. I will post them as soon as their registration link becomes active. Please register early. Even if you don't have a PO number yet...register and leave that part blank. We can also accept credit cards if you wish to pay that way. (You will get an email from me with a link and instructions to pay by CC) So...hope you can join us this year! If you have any questions or sugguestions...don't hesitate to let me know at dtrask at vcsvikings.org or copperdoggy at gmail.com :-) PS: I just remembered....as a special session I think Maddog and Bill may lead those of us who wish to try it in a session on how to build your own Open Source TIVO or DVR from something like MythTV or Freevo....I've seen one...and they rock! You can have a free (except for the hardware) and open source digital multimedia center for your home or school! David N.

I know the GX1, 110, and 150's can. I cannot remember which dimensions or optiplex's the other place had, but I recall that option being there. All I can say is that with Dells you need to make sure you have the latest BIOS because they never have it right the first time. Or the second. Or the third.. I cannot believe how much hardware went bad on the 150's before they realized they didn't turn the fans on, which was A11 I think.

Subject: [K12OSN] PXE boot Dell GX110--was compaq deskpros Aha! It IS possible to PXE boot the Dell gx110. But it's pretty well hidden. In the BIOS, under the 'Boot Sequence', it normally only shows three choices: CD, floppy, & hard drive. In the main BIOS screen, you must scroll down to 'Integrated Devices', and within that, you'll see, among others, 'Network Interface Controller', which is set to On by default. But this is not just a binary, on or off option; rather, it also contains the choice of 'On w/MBA'. Choose this, save the changes, reboot the box, go into the BIOS setup again, and now 'Boot Sequence' will list 'MBA UNDI(Bus1 Slot12)' which is the PXE boot option. Set that option to be the first choice, and voila! the box PXE boots. Hopefully, this info will be useful to someone.

I have a GX-110 here and I thought it was doomed to having to use an Etherboot floppy forever. I set up the BIOS like you mentioned and it booted immediately, Yaaay!!

If you connect to a server using RDP on a Windows workstation, and leave it at the login prompt, it times out then too. Unfortunately I don't have any way to take this further myself, but I do think you need to research the server side on this.

If you use a local Squid proxy, the Dan's Guardian frontend may block it by default. You could juggle ACL lists on Squid itself to block it by name (some proxy places like this can have several IP's). Going further up the chain, you could block it with an IPtables rule as well.

It's a commercial product from a commercial company. As such, there are restrictions on how it can be distributed--that is, you can only get it from Sun. There's no problem with YOU downloading it and using it on your system/server, but Sun doesn't allow anyone else to distribute it. Besides, as K12LTSP is a community effort, its software collection focuses on community-based projects. You have to think about 'free' in terms of speech, not price. > I think this is a GREAT resource, but the lack of documentation > available for a Windows savvy newbie is painful for me, not that I > read documentation, but when I get stuck, I like to have some > reference to fall on... > As mentioned, this is a community effort, meaning documentation is created by the users, including you now. ;-) There is the K12LTSP wiki at http://k12ltsp.org/mediawiki/index.php/Main_Page. There is the LTSP wiki at wiki.ltsp.org. And there is the #ltsp IRC channel, for real-time questions & answers. Rather than asking what others can do for you, ask what you can do for others. When you run into a problem, check the wikis. If you can't find an answer there, post your question to the list, and we'll try to help.

A number of years ago I used "Webalizer" to summarize my proxy logs and turned up proxy tunnels due to the large amount of traffic going to a single address, which I then checked out with "dig". Since students pass the same info around, the same tunnel gets used and the result turns up in the log analysis. So a typical pattern would be that as you close one tunnel, another gets used which in turn shows up in the logs. Some of the proxy tunneling sites had left their DNS server insecure, so sometimes I was able to suck the entire zone file down with "dig @authoritativeNS domain.name axfr". You find the authoritative name server for a domain with "dig domain.name ns". If you have only an IP address, try the inverse lookup "dig -x dot.ted.decimal.address" and see if a domain is listed (not as common as it used to be). -- "History doesn't repeat itself; at best it rhymes." - Mark Twain | John Lucas MrJohnLucas at gmail.com | | St. Thomas, VI 00802 http://mrjohnlucas.googlepages.com/ | | 18.3?N, 65?W AST (UTC-4) | From kbailey at mv.k12.nh.us Wed Mar 28 17:05:27 2007 From: kbailey at mv.k12.nh.us (Karen Bailey) Date: Wed, 28 Mar 2007 13:05:27 -0400 Subject: [K12OSN] push icons out to desktops script Message-ID: We are currently setting up a new server configuration using ltsp6.0 and windows 2003 server.

So far things are working well, however I have a problem that I can't seem to resolve. The thin clients have optical wheel mice and the wheels won't scroll at all. Googling and Ubuntu forum searches haven't solved this one for me. I DO know that this problem is fixed in 6.10 but I don't want to upgrade since I like the idea of the long term support for packages offered via 6.06 lts. I think there may be a fix either with X11 or simply through xorg.conf but I have yet to narrow it down. My servers running 6.06 lts desktop are running: x11-common 7.0.0-0ubuntu45 The relevant section of the xorg.conf page looks like: Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" Option "Device" "/dev/input/mice" Option "Protocol" "ExplorerPS/2" Option "ZAxisMapping" "4 5" Option "Emulate3Buttons" "true" EndSection In contrast, my workstation running 6.10, on which the optical wheel mouse scrolls just fine is running: 1:7.1.1ubuntu6.2 The relevant section of the xorg.conf page looks like: Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" Option "Device" "/dev/input/mice" Option "Protocol" "ExplorerPS/2" Option "ZAxisMapping" "4 5" Option "Emulate3Buttons" "true" EndSection both computers are running the psmouse module Anyway I hope someone can help me out.

There's a RPC connection on (I believe TCP) port 111, the sunrpc port. Then, from there, the client and server can negotiate any UDP port above 2048 for NFS. Now, in practice that usually turns out to be UDP port 2049, but it does not have to be, and I've seen other UDP ports used. That's what makes NFS a challenge to firewall. It's also one reason (no encryption is another) why you should never run NFS on a network that you don't trust, i. e. across the Internet. It's like SMB/CIFS in this way. The real issue here isn't firewalling; it's sniffing. Most of us don't use either SELinux or the built-in firewall on the LTSP servers themselves.

Would it be a better solution to have all the servers in same subnet, with all having certain ip-range for DHCP an/or fixed ip:s for the clients? Or should I put a separate firewall between the servers and internet? I'm trying to find a solution that would be easy and make it possible to have more cheap server-power. Until now I have had one 2*1GHz, 2Gb server for our school and now I'm trying to have 4 quite similar servers together either on one subnet or four separate subnets.

They're old, and corporations that have them are dying to get rid of them, so you probably could get them for free. They also PXE-boot quite nicely, though a BIOS flash sometimes is needed. Then, you could spend, say, $100 a pop for a decent LCD screen. Much easier to read, and much easier on the kids' eyes. --TP _______________________________ Do you GNU!?

Message-ID: Hi everyone! (Help us spread the word about FOSSED...we'll have 3 conferences this summer....one in Maine....one in New Hampshire...and one in Washington D.C.....blog....talk....whatever) :-) Deborah White is a wonderful teacher at the Asa Adams school in Orono, Maine. She is a first and second grade teacher. Linux has brought excitement back into her classroom and she's sharing that with all of us! After looking for a non-technical site on the internet for teachers with Linux in their classrooms...and not finding much...she decided to create one of her own! You can see it here! http://learningwithlinux.blogspot.com/ Deb will be one of our many talented presenters at the 2007 NELS/FOSSED conference! Here's her course description! I will be posting more as we get them. Please encourage your teachers to join us at FOSSED for 3 days of hands-on learning, good food, and recertification credits! :-) Sign up at http://www.fossed.com We'll have lots of techie sessions too! Edubuntu, Virtualization, Open Source apps, politics of deployment, LAMP, Moodle, Python, "Beyond the GUI"....etc. These will all be hot topics. More info will be available here: http://www.fossed.com Register early! Here's the session description for Deb White at FOSSED: "Ok, I've got Linux/Open Source in my classroom...now what?". This session is for non-technical classroom teachers. Other sessions might teach you about the applications that are available with a Linux Operating System. This one will help you learn to think about how to use the application to enhance your teaching. Get lesson plans and ideas that you can use in your classroom or in the computer lab to integrate technology with your everyday curriculum. (If you are a technical person who has to work with classroom teachers, this session might give you an insight into teacher-think. Sign up at http://www.fossed.com David N.

I wanted to see if the built in pxe would ltsp boot. The cards have the 0.99b version of pxe. From what I understand they are pretty common cards. They are also cheap. I bought a lot of 5 and with shipping was $8.98 total. That's less than $2 each. The good news is they work. A couple of minor changes are needed to the server. In /etc/xinted.d/tftp Change the line that reads: server_args = -s /tftpboot to: server_args = -s /tftpboot -r blksize In the file /etc/sysctl.conf Add this line: net.ipv4.ip_no_pmtu_disc = 1 For those wanting to get away from floppy booting this solution will work. Just don't everyone hit ebay at once and drive the price up :) Also, make sure you don't get the cards that have a boot prom socket. Those obviously don't have pxe built in.

It's pretty simple to update, but you do need to boot under DOS to do it. That should give you the ability to use the longer blksize for tftpd, which '-r blksize' disables. The end result will be a slightly faster download of the kernel and initramfs. It's also possible to replace the PXE code with Etherboot. Those who use non-standard dhcp ports might like to do that. The Etherboot docs explain how to flash the Intel nics with the Etherboot code. Jim McQuillan jam at Ltsp.org Vince Callaway wrote: > I picked up some old intel nic's off ebay.
