Message-ID: -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I won't be able to make the meeting in the morning on IRC. I have some obligations I have to be at. Of course Warren is busy working on bug fixes and doesn't have reliable access to the internet for the next couple weeks, so neither of us will be able to update the wiki on this week's meeting without some assistance. If someone wants to save a transcript of the chat and edit the wiki, that would be great. If you don't have wiki access, you can send it to me and I'll put it up. I just need the transcript or a summary of what went on. BTW Warren, my Optiplex GX1 clients boot great, I did notice that the final Fedora 9 installer, unlike the beta, locked up my server with the Unichrome video when it tried to load the GUI on the installer, FYI. Sounds like something's hanky with the new X.org unichrome driver. I haven't had any more time to read up on it. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (Darwin) iEYEARECAAYFAkhCAXEACgkQxWV7OPa/g5GK2gCfQNnhTtfCxlJo0RXqP6OBOjSY W68An1DCNVo80y+pj6b/gxccR+cnnVC0 =0yXM -----END PGP SIGNATURE----- From brcisna at eazylivin.net Tue Jun 3 00:57:20 2008 From: brcisna at eazylivin.net (Barry R Cisna) Date: Mon, 02 Jun 2008 19:57:20 -0500 Subject: [K12OSN] k12ltsp el5 etherboot problem Message-ID: <1212454640.28704.9.camel@localhost.localdomain> Hello List, I done a clean install on two of our schools FCx servers to k12ltsp el5.

These have the built-in 3c905, and they do PXE-boot quite nicely. Matter of fact, I think Jim McQuillan and someone else were selling reconditioned Optiplex GX1's as LTSP thin clients. The catch is that they do need to have a recent BIOS in them, because some of the earlier BIOSes for these boxes did have buggy PXE-boot code in them. I found that out the hard way during a K12LTSP demo. > These two that I tested I had installed > etherboot to the Hd, not that ,that makes any diff, and on the two I > tested I get " no ip address found".

How'd you install Etherboot to the HD? The way I do it is by doing "cat MyEtherbootImage > /dev/hda". Note that I didn't specify a partition, but rather the HD itself. Also, it's possible that the Optiplex is configured to PXE-boot, and further, that it has one of the early buggy BIOSes in it. Best to turn that off. IIRC, it's called "Network boot". --TP From nadavkav at gmail.com Tue Jun 3 20:42:43 2008 From: nadavkav at gmail.com (Nadav Kavalerchik) Date: Tue, 3 Jun 2008 23:42:43 +0300 Subject: [K12OSN] PulseAudio Client with ESD Server Message-ID: <4219988b0806031342h707b4357w559926a7bf49700f@mail.gmail.com> Hi List :-) i hope this not old news to you all but i just figured out how to play sound with ALSA's PulseAudio Client/plugin and redirect it to ESD server on any Student's machine :-) i have fedora 8 installed (i have upgraded from k12ltsp fc6 with yum) with PulseAudio 0.9.10.

When doing all my configuring on this server for dhcp range, etc, I had commented out the 'next server' directive in the dhcpd-k12ltsp.conf file. I didn't realize that with this commented out it seems as dhcp = 0.0.0.0 to clients. Once I uncommented the 'next server' line and restarted the dhcp server the etherboot client machines booted fine. I don't know why the pxe boot machines booted up ok? I'll put my dunce hat back on for a while longer!

If you add the following to the "client" section above this client will work at 1024x768 XSERVER=1024x768 For printer to work you need to define the printer under cups which can be done using a browser and pointing it to http://localhost:631 and adding this printer as JetDirect printer. BUT before you do that you need to fix the IP address of this client machine by editing dhcpd configuration file. Remember to restart services cups, dhcpd after changes (or reboot the server). -- Regards, Sudev Barar Read http://blog.sudev.in for topics ranging from here to there.

I would get a quad core if you can afford it. Also unless you are going to use icewm I would get more ram too. Just make sure your hardware can support a PAE kernel if you want to stick to 32bit OS which I assume you do.

Not necessarily number of concurrent connections but numbers of clients per server. Please post your server specs, switch setups, brands maybe, as well. I would guess people here would like to see some real world k12ltsp client to server possibilities. Most we have is 40 per server, but our servers are lowly 2.4 ghz processor 3-4gb ram,but seem to work well this way. Never really tried to monitor the most concurrent connected clients.

But if you setup 2 > drives in a raid 1 isn't everything mirrored automatically? Only if you set it up that way. I don't use hardware raid because I can't control how the drives will be put to use. Hardware raid will use the entire drive. I will typically create multiple partitions and join them as needed to make raid components and/or LVM components. Example: 2 250GB drives each drive is split the same way: 100M, 1GB, 5GB, 10 GB, 50GB, 100GB, rest The 100M are raid1 /boot, 1GB are independent swap, 5GB is raid 0 /tmp, 10GB is raid1 /, 50GB is raid1 /var, 100GB is raid1 /usr, rest is raid1 /home This gives me a backup boot partition (I set drive 1 as primary boot and drive as secondary), 2 GB swap (for a 1GB RAM machine, adjust up to total 4GB swap), 10GB /tmp that is very fast read and write, 10GB very fast read /, 50GB secure logs and email and other stuff I don't want to loose, 100GB fast read never write /usr application space, and loads of secure data space for users. Complicated? Yes. But I get to set it up to suit the needs of the system. I can clone the box by powering off, replacing drive 2 with a new blank drive, booting into runlevel 1, partitioning new drive 2 the same as the old, rebooting and letting the raid sync it all up. (Yes, I can also clone it with dd but that assumes identical drives. With the raid method I can have a new drive that is 300 GB because the 250's were sold out). Yes.

He means that if you are using hardware RAID it actually sees the two drives as a single drive. You can't partition some of the drive as RAID 1, some as RAID 0, and some as just a standard partition.

Hmm...I'm not sure why that would be desirable outside of an academic exercise...but I guess if you're testing, it might be fun to play around with. I just don't see it as enough of a compelling advantage over the benefits of hardware RAID, though. And as for moving the drives to a different RAID controller, actually that can be done if both controllers are the same model, often even the same brand (I've done this with Compaq SmartArray 3200's to 5300's). This works because the RAID ID is stored on the drive as well as the controller; the original purpose of this is so you can replace the controller and not lose your RAID if said controller goes Tango Uniform. This is why my district tends to standardize on one or two hardware platforms and then keep a spare RAID controller around. I just put the OS (/boot, /, /usr, swap, etc.) on a RAID 1, and then /home on a nice, big, honkin' RAID 5 with at least six spindles. Great performance that way, and good SATA disks are cheap. You want to expand your volume group with another RAID? Much easier with hardware RAID's "one disk" appearance to the OS than software RAID. The point about swap, though, is a valid one, so I simply add enough DRAM to where it isn't a problem anymore. :-) That's, of course, what should be done anyway if swapping becomes an issue. --TP From jkinney at localnetsolutions.com Mon Jun 9 02:06:03 2008 From: jkinney at localnetsolutions.com (James P.

I know many people love 'em and trust but I don't. I've had to many mission critical system become crippled until a restore from backup could happen because the controller died and it's out of production and the replacement one can't use the drives until they are initialized, i.e. wiped out blank and reformatted by the new controller. I can take a Linux software RAID drive pile and move it to a new machine entirely and I'm good to go. > > Hmm...I'm not sure why that would be desirable outside of an academic > exercise...but I guess if you're testing, it might be fun to play around > with.

My internal testing showed a performance hit of about 1-3% (about 4 years ago) using software raid vs hardware raid in a sequence of real world tests (i.e. combination read/write work called by multiple clients). > > And as for moving the drives to a different RAID controller, actually > that can be done if both controllers are the same model, often even the > same brand (I've done this with Compaq SmartArray 3200's to 5300's). > This works because the RAID ID is stored on the drive as well as the > controller; the original purpose of this is so you can replace the > controller and not lose your RAID if said controller goes Tango > Uniform.

I have been a HUGE advocate of skip the extended warranty and spend the same amount of cash to buy replacement parts at the beginning of the server lifetime. Compaq and Dell raid cards have provided me the most trouble. Dell has been a nightmare. Can't stand 'em. Won't recommend 'em. Don't support 'em.

Much easier with hardware RAID's > "one disk" appearance to the OS than software RAID. I no longer use raid 5. Got bit too many times with systems that would have 2+ drives fail within a single day. Noticed it happened on systems with sequential serial numbers more often that mixed numbers. With software raid, I can create partitions to squirrel away config data, install media, etc and still be able to create raid systems and used drives from different vendors, brands and even sizes so I don't get the "next in line" failures. My current preferred setup is raid 10, stripped mirrors: use an even number of drives, pair them into mirrors, strip across the pairings: single speed writes for small chunk size data, distributed writes for large chunk sizes, blazing fast reads (each drive of the mirror can read independently of the other so concurrent reads!) and solid data security (loose a drive in the mirror the stripe is still live - with a mix-n-match drive pile sudden loss of two drives is minimal and system can theoretically loose 1/2 the total amount before disaster). Raid 5 in my mind _requires_ hardware raid to offload the checksum/parity calculation part. Drive space is cheap enough that a full mirror is no longer too costly to use. > > The point about swap, though, is a valid one, so I simply add enough > DRAM to where it isn't a problem anymore. :-) That's, of course, what > should be done anyway if swapping becomes an issue.

I believe it's a 16-bit application. They never upgraded it because newer versions requires Windows SBS with Microsoft SQL Server (which they don't have) and converting the data files to the format of the newer version isn't even free (!). Right now they are storing the data on a Samba share on a Linux fileserver. The app works and they know it inside out.

It is a major security hole as it open a root shell on the client with no password. That said, it could still work by having a root user environment that only calls a "fake login" than uses ssh to connect back to the server. Basically an autorun script that asks for the username, feed that into the ssh call and then they get a password prompt from the server in the ssh session. Make the wrapper script a permanent loop and an autorestart in .bashrc if they -C it to death. You could also setup a generic user user on the client and immediately have the root user su - and do the login stuff from there.

Root does but normal users don't. There are several ways to make this work. Ideally, you want to preserve the system security but writing to the parallel port is maybe not a security problem for your situation. If so, change the permissions on the device to be 666 and everyone can read and write to it. A more elegant way is to modify the hal settings and have the device initialize with the correct permissions. You will want to edit in the udev settings. In redhat derivatives, it's in /etc/udev/rules.d . From there you would make a new file that begins with a number higher than the default file (so it gets run after -* double check this. I may have it backwards.*) and model the config after the default section on printer ports. You can also set the application up so it is setuid root (chmod u+s ) but that may be an issue in a gui like gnome (It looks for setuid root files and gripes as it _is_ a security risk). Another option is to use sudo and setup that application for all users to not require a password and then change the application name to something like sudo-myapp and make a global alias myapp='sudo sudo-myapp'.

Another issue could be that diffent distro's use different files. I seem to remember from my redhat days that they used "$HOME/.Xsession".

Search for this. It is a three step process. Takes about 10 mins or less to do each client. You will need a floppy drive available to ( at least) temporarily hang on each client as this is what the eb_to_hd file copy from. This works for a pretty clean setup as you don't have to worry about kids popping out the cd and throwing it in the trash:) If it will only be adults using these machines the aforementioned setup would prolly be simpler for You. Note : This will of course wipe the HD clean!

Also on the etherboot site there are several ways to use gPXE. Perhaps reflashing the BIOS of your motherboard may be a little extreme, but there are good instructions to use it from floppy, CD or USB key. gPXE is nice because the server will already detect and use it with no additional configuration, and also because it will work with hundreds of network cards. http://www.etherboot.org/wiki/howtos Also, you can boot to a Knoppix disk in text mode (at the initial prompt type knoppix 2 ) and connect to the LTSP server with: X -query server You need to have your network connected, of course. Some Knoppix variants do this automatically, the rest you can 'sudo su' to get to root and then run netcardconfig. Choose DHCP, it should pick up an IP from the LTSP server. thx, Scott S. > 2008/6/12 Fajar Adianto >: > > Guys, how can I make my clients boot from CD or HDD?

K12LTSP 5EL even ships with a yum config file for the rpmforge (Dag Wieers) repository. You only need to set enabled=1 in /etc/yum.repos.d/k12ltsp-rpmforge.repo. Nils Breunese.

If you are just installing this, you should be using the EL5 version based on Centos with update support for several more years. Ver 6 is based on fedora FC6 which has a much faster life cycle and is already past update support. But to answer the question, if you set up 2 nics during the install, all you should have to do is have the client set for PXE boot and plugged into the server's eth0. -------------- next part -------------- An HTML attachment was scrubbed...

In the server, for the NIC supporting the clients you want a gigabit card, with each client having a 100Mb NIC. You might, *MIGHT* get away with a wireless NIC in the server for eth1, the NIC that connects the server to the internet/school's network, but it depends on what the server is being used for. If it's for a lot of internet stuff, I think the users will be quickly frustrated by the performance.

My understanding is the goal of the current generation of UI switches is to do it's job without the system (including the software) ever realizing a switch is even there. (Which makes sense when you consider you've never seen a "device driver" for a KVM switch.) They'll fake the presense of a mouse when the real mouse is switched away to something else, some of them will even fake a response to a screensize query when necessary, and any special functionality is just between the keyboard and the switch with no software on and no involvement by the computer. Generally this generation of devices is identified by the term "KVM" ...which wasn't used for earlier generations if you can remember back that far. Even so it's usually a good idea to switch the display to a system before rebooting it, so the system always boots up with "real" hardware there and never depends on the KVM fakes. And a few systems may get the wrong idea about screen size no matter what when a KVM switch is in the path, and I don't know of any general solution. (Sometimes you can "force" the system configuration to use a certain screen size rather than query the hardware, which will work fine until you change out the monitor.) Many KVM switches have some sort of "maximum resolution", and won't allow the system to set the monitor to a higher resolution no matter what (or if they do allow it, it won't work right as the screen will be distorted, perhaps so badly you can't even read it). But that's a function of which KVM switch, not of the OS. Most KVM switches I've seen are good at least to 600x800 and usually to 768x1024, but beyond that many poop out. thanks! -Chuck Kollars From microman at cmosnetworks.com Sun Jun 15 15:55:01 2008 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Sun, 15 Jun 2008 11:55:01 -0400 Subject: [K12OSN] usb wireless nics In-Reply-To: <000001c8cda7$535bb250$fa1316f0$@ca> References: <480E38B6.2080307@snarlnet.com> <000701c8a4d1$77a79290$66f6b7b0$@ca> <480E81CC.5050509@paasda.org> <000901c8a4e0$35cb88e0$a1629aa0$@ca> <480E92CF.9040502@paasda.org> <000a01c8a4e3$6ad7acf0$408706d0$@ca> <480EBE16.7060800@futuresource.com> <000d01c8a971$c88d2130$59a76390$@ca> <481738DB.50705@cmosnetworks.com> <001201c8cd76$b9dd9240$2d98b6c0$@ca> <4852CC80.6050103@scheie.homedns.org> <000301c8cd92$a3e014b0$eba03e10$@ca> <0F2617ED-345F-495D-93C1-AF9EFCF1EA85@breun.nl> <000001c8cda7$535bb250$fa1316f0$@ca> Message-ID: <48553B55.90503@cmosnetworks.com> Actually, I use the K12LTSP 5.0EL normally for my "regular" server CentOS 5 installs. Works like a charm. +1, though, to Peter's comment about going with wired on both sides (and Gig-E on eth0), even if you're just testing it at home. Here's why: I, too, run K12LTSP at home. One of my tests a few years back revealed that TuxType will regularly suck up 73Mbit/sec at its default full-screen resolution. TuxMath and ChildsPlay show similar numbers. Now, imagine yourself on a hub (no, not switch--I mean a hub) that speaks, say, 100 Mbit/sec. Understand that collisions are going to slow down even a single session of TuxType. Now, let's say you add another TuxType game session on your second terminal. Oops, not only did you just oversubscribe your server link, but collisions have just made even your two TuxType sessions nearly unplayable. Now consider a computer lab of 15 kids instead of two. Wireless technology isn't switched. It's actually a form of hub. This means that the 54Mbps that you get from that wireless connection is shared among all wireless computers that have associated to the wireless access point. You essentially have a 54Mbps hub. NOT good for LTSP. Even if it were 54Mbps switched (which it isn't), you'll still oversubscribe your server NIC--and with TuxType, TuxMath, or ChildsPlay, your client NIC as well. Gig-E is cheap and is built into virtually all desktop and laptop motherboards since 2005. If yours is older, Linux-friendly Gig-E NICs are $19.95. Realtek 8129/8139 100Mbps NIC's (exceedingly LTSP-friendly) can be had for $5. Go wired, man; if you're gonna do it, then do it right. Seriously. --TP _______________________________ Do you GNU ?

Share that printer on the network Go to your windows box and add a printer... In my case I use: https://printserver.localdomain:631/printers/pdf >From Windows, print to the PDF network printer Basic setup done. (I have this setup on a debian box, not on a K12LTSP box, so there are some settings difference) On my debian box, the "printout" will land in $HOME/PDF/ for all local users and Anonymous SAMBA output lands in /opt/smbshare/PDF-Printer/ (/opt/smbshare/ is a directory I have set up for anonymous samba sharing) So you might want to check the settings and/or watch the log while you do a test run. Now set up the destination directory to be shared over the network as well. (Using samba/ftp/what ever you want). Note of caution.. watch the file permissions. I can see someone printing out something that someone else either should not see or accidently deletes before User1 can get to it. -- http://gentgeen.homelinux.org ############################################################# Associate yourself with men of good quality if you esteem your own reputation; for 'tis better to be alone then in bad company. - George Washington, Rules of Civility From rob.owens at biochemfluidics.com Mon Jun 16 16:03:15 2008 From: rob.owens at biochemfluidics.com (Rob Owens) Date: Mon, 16 Jun 2008 12:03:15 -0400 Subject: [K12OSN] PDF file creation In-Reply-To: <4856758D.7020202@portsmouth-college.ac.uk> References: <4856758D.7020202@portsmouth-college.ac.uk> Message-ID: <48568EC3.7080409@biochemfluidics.com> PDFCreator asks if you want to do a "server installation" or something like that.

As I recall the client side of LTSP is on eth0 by default, so eth1 would go on the cable modem and eth0 goes on the LAN side (not WAN side) of the Dlink. Your clients also go on the LAN side of the DLink. This assumes you want to use the LTSP server as your router/firewall instead of the DLink. If this is the case, then be sure to *turn off* DHCP on the DLink and let the LTSP server handle that task too. The WAN side of the DLink will not be used. The client's default route would point to the LTSP server (be sure to turn on packet forwarding if you have PCs that need to pass traffic through the server). The other way to do this is to run a single NIC LTSP server (only eth0) and plug the LTSP server and all clients onto the DLink LAN side, turn off DHCP on the DLink but continue to use the DLink as your router/firewall with the WAN side connected to the cable modem. In this scenario, the DLink would be the default route for all clients (including the LTSP server). > Also, during the ltsp install, the eth0 was designated x.x.x.254 and > eth1 dhcp.

I use KDE and installed the KDE admin tools, which adds an "Administration" item to the main menu. The exact setup depends on your ISP.

Subject: Re: [K12OSN] usb wireless nics Actually, I use the K12LTSP 5.0EL normally for my "regular" server CentOS 5 installs. Works like a charm. +1, though, to Peter's comment about going with wired on both sides (and Gig-E on eth0), even if you're just testing it at home. Here's why: I, too, run K12LTSP at home. One of my tests a few years back revealed that TuxType will regularly suck up 73Mbit/sec at its default full-screen resolution. TuxMath and ChildsPlay show similar numbers. Now, imagine yourself on a hub (no, not switch--I mean a hub) that speaks, say, 100 Mbit/sec. Understand that collisions are going to slow down even a single session of TuxType. Now, let's say you add another TuxType game session on your second terminal. Oops, not only did you just oversubscribe your server link, but collisions have just made even your two TuxType sessions nearly unplayable. Now consider a computer lab of 15 kids instead of two. Wireless technology isn't switched. It's actually a form of hub. This means that the 54Mbps that you get from that wireless connection is shared among all wireless computers that have associated to the wireless access point. You essentially have a 54Mbps hub. NOT good for LTSP. Even if it were 54Mbps switched (which it isn't), you'll still oversubscribe your server NIC--and with TuxType, TuxMath, or ChildsPlay, your client NIC as well. Gig-E is cheap and is built into virtually all desktop and laptop motherboards since 2005. If yours is older, Linux-friendly Gig-E NICs are $19.95. Realtek 8129/8139 100Mbps NIC's (exceedingly LTSP-friendly) can be had for $5. Go wired, man; if you're gonna do it, then do it right. Seriously. --TP _______________________________ Do you GNU ?

See > 'yum --help', the command is remove, not uninstall. > Freenx with the NX client is much nicer, though. Don't give up on it. The trick is that the commercial NX server always uses the same key that matches the one built into the client, where freenx generates unique key pairs for each install. Just use putty to ssh to the server as root and cat /etc/nxserver/client.id_dsa.key, and in another window open the NX config screen and push the 'key' button. Then delete the existing key contents and paste in the correct one including the ---BEGIN and ---END lines. If you have trouble with this, use winscp or other means to transfer the file over and use the 'import' button. When you get it right you won't have the authentication failure error. If you have firewalling involved you may also want to make sure the "advanced/disable encryption of all traffic" box is unchecked so the connection will run over port 22. -- Les Mikesell lesmikesell at gmail.com From jim.c.christiansen at gmail.com Tue Jun 17 16:24:16 2008 From: jim.c.christiansen at gmail.com (Jim Christiansen) Date: Tue, 17 Jun 2008 09:24:16 -0700 Subject: [K12OSN] Anyone done an upgrade rather than a wipe recently?

Migrate homes and user authentication to a backup drive, verify with rsync and wipe out the cruft and start fresh. You will need to remove all the really old user preferences anyway so pretty much most of the dot files go. BUT (!!!!!) be careful of mail folders and ssh keys.

I've seen teachers take personal calls in front of their class. Students at a college I taught at were caught using cell phone cameras to send the test to a friend with notes. Answers were sent back by text message. I had them expelled. Realistically, the cell phone for kids is so their parents can keep that leash while allowing some freedoms. It's always argued that "if little Johnny needs to get in touch with mommy..." but it's always used for endless kids phone drivel (Has anyone ever listened to the conversations of a teenager?!). I implemented a policy in my college classes of taking my phone off at the start of class and visibly turning it OFF, not just silent, and after the first time the majority of students did the same. During exams, any cell phone that rings or buzzes was an automatic F. As no one in a classroom in K12 has responsibilities for emergency action other than notified by the intercom, the instant access by cell phone is a bad idea as it is just a major disruption of thought process.

I've been monitoring the e-mail list for about 4 months and have a couple of questions. 1. Is the latest / greatest K12LTSP 6.0.0 as seems to be indicated on the download page of the K12LTSP Wiki? 2. Is there really an advantage in speed going with 64 bit rather than 32 bit for the server? I ask because I can test 32 bit locally, and don't have 64 bit available. BTW, the lab will be 20 seats in a K-8 environment. I'm planning on running a lightweight window manager rather than KDE or Gnome. 3. The lab will need to also speak to a Windows server for legacy student files, thus I am looking at Samba and smbmount. Any problems in sharing data this way? 4. Is there a good writeup on load sharing between two K12LTSP servers if we decide to go a bit fancy? 5. I'm going to be purchasing new small form factor diskless workstations for the lab. Are there any noted problems with either the Devon IT 6020 series or the eBox-2300 and K12LTSP 6.0.0? (It looks like the Diskless Workstations LTSP Term 1000 is a rebranded eBox-2300. Is this correct?) 6. Are there any other words of wisdom you would like to supply? BTW, I have been playing with LTSP/K12LTSP off and on for about 5 years, but have not done a full, not-recovered-from-the-dumpster installation before. My test server is a PIII/450 which was given to me. I am very, very impressed with the ease of making K12LTSP work, and am looking forward to getting this lab in to production.

The EL version uses the same ltsp version and many of the F6 applications are the same (version). The difference between F6 and F9 with LTSP is almost night and day. Keep the user data (/home with ssh keys and mail stuff and dump the rest) and do a fresh install. Keep in mind that Fedora (and redhat derived products) are far more invested in Gnome than KDE. Also remember that Fedora is a fast moving test playground and while things work, they don't always work smoothly. The F9 is excellent for my uses but I don't use KDE.

While the DHCP load balancing can be used to split the boot up and ultimately the server each client run from can be set this way, the application load balancing is the issue I'm most interested in and currently working on. Picture this scenario: Large school with 800 students and 5 LTSP servers. Several classes are fully populated with clients and make extensive use of the heavy applications. Other classes do lighter stuff. The teachers in the heavy use room will see the LTSP as slow. If there is a way to dynamically shift the workload between running server so a single server doesn't bog down under a classroom activity while others are barely in use, that's a huge improvement. This process is very technically challenging at this point. As each running application has it's own PID, memory and threads, plus all the associated communication credentials for X, migrating these processes to more cpu's on more machines is not a trivial thing without disruption that the client sees. LTSP5 does this at login time with the ldm server load calculation. However, once connected, the client is firmly attached to a single server. If it bogs down, all clients bog down. The long term solution is a process used in high-end scientific computing called single system image. The OpenSSI project is working towards a solid solution in the lines of LTSP and OpenSource. There are commercial projects like Mosix that already have this capability. This process provides for a stack of servers that all provide cpu and RAM to the cluster. A mother node monitors the load across all machines and can migrate a process to a less used node as needed. As this process migrates, all of it's associated records, ram and connections also migrate seamlessly. The client never sees the change. This also allows for hot node replacement as a node can be brought down, pulled, repaired and replaced, and then restarted with no effect on clients other than the loss of a bit of speed. This has a ways to go before it is ready for use. It is under active development and constant testing. Imagine the fun we can have when our kids can reply to a normal students comment of "I use a Microsoft windows machine every day at school." with "I use a 12 node, 96 cpu super computer!" :-) > -- James P.

OP only mentions load balancing between two k12 servers so my suggestion. I have snipped out most of what you said but yes that would be ultimate. I did try running open-mosix cluster along with a k12 but that was three years back and the process apperantly died when migrating from node to node. Have not had the chance to put together a bench thereafter to see if that or some other cluster server project is able to work. Will look out for some positive news on this front. -- Regards, Sudev Barar Read http://blog.sudev.in for topics ranging from here to there.

Instead, you might look for the eBox-4300 which has, if memory serves, a 500Mhz processor, compared to the 2300's 200Mhz processor. It comes in the same size case, perfect for mounting on the back of an LCD monitor, but it also costs twice as much, ~$230 compared to the 2300's ~$110. I think the Devon 6020 series start under $200.

There's only one dhcp server, and no failover. Not the best solution by a long shot, but it was relatively easy to set up.

(i use those platforms on my personal machine and they are great but they are too much community and not commercial for schools) we use kde because it has features gnome did not have (even now, maybe ?) : * KDM ! - some many useful features. * kde's underlying framework that can be locked down very easily (from administrative pov) * it is faster then gnome. * it takes less memory too. * wider variety of application (minor reason). this is way we choose kde although redhat loves gnome. :-) On Thu, Jun 19, 2008 at 4:24 AM, James P.

Our students have demonstrated their ability to use these new technologies often better than us. It is us adults that have failed to bring authenticity to them by providing them the means to used these tools to learn, thus, they only use them to play. Our school hasn't banned cell phones or Myspace for that reason, however, we do "encourage responsible use" at least to the level any adult would be expected to maintain. We purposefully keep these things around to remind us of the work we need to do to allow them to use these tools to learn. Our students generally have respectful interactions with us when we redirect them from social distractions be them technological in nature or not. In an effort to encourage our students to use the technologies for learning, I have been working with teachers to begin moving some of our more lecture-based classes to a eLearning system (Moodle) and free those teachers to use the time to meet individually with students. The goal is that students learn to "work" in the way adults do. That is, scheduling meetings with teachers, attending large group meetings (they could be classes). They would then start to use technology (e-mail, text messaging, blogs, discussion lists) in the same way adults do - to learn and communicate to be more effective at our work. I currently have two tech students I'm working with who have this kind of relationship with me. One is a 7th grader who is building our new school's web site on Drupal, the other is a 10th grader who has been using Linux at home since he was 11 and knows far more about open source than I do, he currently maintains our K12LTSP system and has built our new Moodle system from the ground up. He actually trained me on how to create a course and gave me a tour of the features.

Basically a power-pc chip has it's top surface replaced with laser diodes and a fiber block gets attached. It then connects to an optical switch which route cpu/ram signals between cpu's. Cooling is a chore so no commercial production any time soon. But the stacked 8-core process has promise. 8 cores with optical interconnect each separated by a diamond layer to disperse the heat to the edges. The heat sink is on 4 sides, power in at the bottom and data IO on the top. > > --Huck > > James P. Kinney III wrote: > > On Thu, 2008-06-19 at 10:44 +0530, Sudev Barar wrote: > >> 2008/6/19 James P.

Message-ID: <8b88203f0806192048u53dd1906md4efaee5ae99f9d7@mail.gmail.com> Hi guys, Thanks the thoughts. On the upgrade/wipe-install question. Today I backed up the group, shadow, password bla bla bla bla bla files, unplugged the back-up rsync drive and did a full wipe then new k12el5 install. Put back the vital parts of the necessary conf files, altered the network settings in the template ltsp dir for my different network subnet, did the k12 initialize, plugged in the second drive, mounted it then rsynced back to the users homes and perms of the users... Everything is good to go for the fall start of school! Now for the other two boxes! OK so. what I need to do is to drop into EVERY users' home and remove a set of files... I've search high and low, through the lists going back 3 years or so and can't find reference to any script that did this. I think there was one that several contributed to that we used to trash the dot mozilla, .g* files, and I used it also for getting rid of the dot cxoffice folders. I'm not great at shell scripts.

It tries to only delete files in actual users' homedirs by only acting against those UIDs that are greater than 500, thereby missing the various system IDs.

Yum recognizes the obsoletes tag on sos and installs sos and removes sysreport. I don't know 'updated', but maybe running 'yum update' fixes this? You can probably also remove sysreport first and then install sos. Nils Breunese.

If the cd fails you might rm -Rf something you don't want to. Better to rm the full path instead of cd to it. I thinkthis issue came before too.

Message-ID: Spread this message far and wide! Register soon! Hi all, I'm pleased to announce the 2008 edition of FOSSED (Free and Open Source Software in Education) at Governor's Academy in Byfield, MA on August 3-6, 2008. FOSSED has been in existence for 6 years providing incredible professional development opportunities for educators and techies from all over North America. The original FOSSED held each year at Gould Academy in Bethel, Maine has been a smashing success and has featured such notable FOSS celebrities as Jim McQuillan (founder of LTSP), Jon "Maddog" Hall, Warren Togami (founder of Fedora), and many more. For the past two years we've expanded FOSSED to another conference held at the University of New Hampshire (UNH). This year we're simply moving a little further south to the beautiful campus of Governors Academy in Byfield MA. http://www.thegovernorsacademy.org This year we're adding to and changing the focus of FOSSED a bit and giving developers an opportunity to come together, work together, learn and really get a chance to find out what's really going on in the world of FOSS in education. Educators and developers coming together. We're pleased to announce that Walter Bender of SugarLabs.org (read more here: http://www.openeducation.net/2008/06/03/walter-bender-discusses-sugar-labs-foundation/ ) will be one of our keynote speakers for FOSSED 2008. As the conference registrations develop we'll be inviting many more notable folks from the world of FOSS. We'd like to invite you to join us! Bring yourself...bring a team! Participate, present, sprint, or just listen and learn. We'll provide the atmosphere, the time, and the experience...all we need is YOU! We've made it easy for you to attend. One price includes EVERYTHING! Room, meals, and conference....all for one low price. $495 for on-campus and $445 for commuters 3 days of hands on learning, interaction, and more!

I think as-is, that would delete all of the home folders since it sets the variable "users" and uses "user" which will be empty. Also you don't want the extra stuff from -l in your ls listing and you probably want to make sure the cd succeeded before removing anything. -- Les Mikesell lesmikesell at gmail.com From jschubert at shaw.ca Sat Jun 21 16:49:06 2008 From: jschubert at shaw.ca (Jeremy Schubert) Date: Sat, 21 Jun 2008 10:49:06 -0600 Subject: [K12OSN] squid and squidguard setup Message-ID: Following the sintructions at http://www.cyberciti.biz/tips/howto-rhel-centos-fedora-squid-installation-configuration.html, I'm trying to install squid and squidguard.?

It might be overkill for this, but OpenNMS (http://www.opennms.org) will monitor the things that snmp reports - and your router and switches as well if they support snmp. They have a yum repository that makes it fairly easy to install now. -- Les Mikesell lesmikesell at gmail.com From nadavkav at gmail.com Sat Jun 21 19:31:52 2008 From: nadavkav at gmail.com (Nadav Kavalerchik) Date: Sat, 21 Jun 2008 22:31:52 +0300 Subject: [K12OSN] one year performance graphs and statistics for two server setups we use In-Reply-To: <485D4706.1010706@gmail.com> References: <4219988b0806211056u7d0cad46t4b21c98c9f6e18e6@mail.gmail.com> <485D4706.1010706@gmail.com> Message-ID: <4219988b0806211231k191c86eeueafb5cfe90bea036@mail.gmail.com> Cacti already monitor SNMP. i was looking for the exact SNMP strings you might think help me monitor router's bottle-necks , NIC's IO buttle-necks, cpu wait for IO, squid wait for...

It will have default graphs for CPU use that color-code the user/system/wait times. I don't think there is anything specific for NIC buffers but it will graph interface errors, total current connections, and connections being opened in in/out bound directions as well as interface bandwidth. And it can notify you via email, sms, a jabber chat room, etc. when something goes wrong. But there's probably only a few things that matter - one will be total outbound bandwidth for screen-intensive things, another will be CPU use for things like flash that all run on the server CPU. These are easy to see even with cacti. Another is disk head contention where multiple users/processes all are waiting for something in different locations on the same disk. That one is harder to diagnose - and likely the most common bottleneck. -- Les Mikesell lesmikesell at gmail.com From nadavkav at gmail.com Sun Jun 22 05:15:00 2008 From: nadavkav at gmail.com (Nadav Kavalerchik) Date: Sun, 22 Jun 2008 08:15:00 +0300 Subject: [K12OSN] one year performance graphs and statistics for two server setups we use In-Reply-To: <485D5D94.6030506@gmail.com> References: <4219988b0806211056u7d0cad46t4b21c98c9f6e18e6@mail.gmail.com> <485D4706.1010706@gmail.com> <4219988b0806211231k191c86eeueafb5cfe90bea036@mail.gmail.com> <485D5D94.6030506@gmail.com> Message-ID: <4219988b0806212215l60af1e9dr24ef7d78a2642161@mail.gmail.com> wow :-) that helped me allot, thanks ! i will look into it and see if i can add these probes to Cacti, if not... i will checkout opennms.

Any suggestions? Assuming you are using a rpm distro like K12LTSP, you need to install the -devel package for berkely-db. The rpm stuff splits binaries into run-time and development parts and has two packages as a result. If you are using the non-rpm install of Berkely-db, you will need to compile the berkely-db from source and install it, verify that ld_so_conf is correct for the install and recompile the squidguard. > Thanks, > Jeremy > > -- > This message has been scanned for viruses and > dangerous content by MailScanner, and is > believed to be clean. > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see -- James P.

Yes that should be $users in all locations. And yes the rm line is dangerous as it will try and run whether the cd happens or not. "-1" makes things be a single column from the ls command. A better form would be : for user in `ls -1 /home` do for dotfile in .gnome .mozilla .cxoffice do rm -rf /home/$user/$dotfile done done If you know you want to clobber all the same files in all /home directories rm -rf /home/*/.mozilla will remove the .mozilla directory in every /home directory on the system.

Does anyone know of a computerized system for keeping track of attendance that would function with the kids themselves (k-12) entering their own comings and goings into the system? As I sit down to design this I'm imagining all kinds of data integrity nightmares with kindergarteners clicking "sign in" and "sign out" buttons that are next their (or someone else's) name. This would be some sort of kiosk by the front door. I'm thinking that if I use a web interface (I am a web programmer), I'll use a thin client for this. This is for a free school, where kids can enter and leave the school at different times. There is no "home room" or designated check in time. Right now, kids sign in on paper, but it is making reporting and tracking trends difficult. I'm toying with the idea of using facial (and possibly voice) recognition software. So, a kid comes in, sticks their mug into a camera and clicks a button that either says they are coming or going. If the picture can't be recognized, it is stored and flagged for human identification. I have no idea how to do that though. One other design problem is that we need some record of who's in the building that we can grab if there's a fire or other emergency. That's where the sign-in sheet on the clipboard really shines. Any brainstormy thoughts at all about pitfalls or solutions would be helpful at this point. Anyone else have a situation similar to this? ck From mneves at ccems.pt Mon Jun 23 10:48:10 2008 From: mneves at ccems.pt (Marco Neves) Date: Mon, 23 Jun 2008 11:48:10 +0100 Subject: [K12OSN] User authetication problem - Active Directory vs K12LTSP References: <20080622160019.51221619BF3@hormel.redhat.com> Message-ID: <002801c8d51e$a382e9a0$5716a8c0@portatilhome> Hi everyone, I?m trying to make the user of K12LTSP to autheticate in a 2003 server (active directory).

Or maybe just a fingerprint swipe. I wouldn't bother with the in or out designation as they will goof up and do the wrong one or figure out a way to game the process. Access badges with rfid tags are often used in business for entry/exit security. So the thin client can do USB stuff very easy. There are many card readers that are USB devices and Linux friendly. The bar code stuff is seen as just text input anyway. If you need the direction details, just use two readers, one for in and one for out. You will need to associate the id number with a username (easy - hash lookup or dictionary). One associated you can have some fun with it! Pop up a picture on the screen of the student (or teacher) and use festival to greet them audibly ("Good morning Mary Sue", "Goodbye John Smith").

Single scan (forget the in/out buttons, just have the current state ready) will tell you just that something got scanned, so there is a problem right there. The kids can scan in and -not- enter or leave. All the tokens not attached permanently can be exchanged .... Can you do something of a bit futuristic nature, since the future will happen soon? What I have in mind is "chipping" the kids with tiny RFID chips. Works for my cats. I had to change the design from a single scanner with the door mechanism to three scanners, so that I really know where they are. I've seen cats and kids change their minds and back out after opening the doors to go in -:) Of course the above was somewhat in jest, but there is no good solution without the use of biometrics, and even those can be fooled. One inexpensive way is to count heads going in and out - web cam, simple software. Make sure you push the video to an external server. In case of an emergency, you'll now -how many- kids are in, to find out -which- kids, you'd need to view the video. As far as I know, this is acceptable level of data for emergencies.

Yep, that's exactly what I meant. Just like kung-fu. It's not uncommon for geeks to add the "-fu" suffix in a playful way of saying "wizardry."

The school I'm using it at has about 75 thin clients. Currently we're using an smbldap serer and two dual-core 4GB ram servers. I'm gonna spend 5 or 6 K today on a 64bit 8-core 16GB ram monster. (well monster compared to what I have right now) Now I'd like to just add this new box to the network as another ltsp server using 64 bit edubuntu or fedora+ltsp, but so far my couple of months with a 64 bit desktop have me thinking this might not be the best approach. The main problem I have is that Adobe's has yet to get off their butts and product a 64bit flash plugin. I know I can use the nspluginwrapper but it only seems to work about half the time, and when it does work, half the time sound doesn't. I imagine that sound through the thin clients will be even more troublesome. The other option I have is to load centos5.1 or ubuntu 8.04 on the new server and something like vmware server to slice it up with 4 or so 32bit guests. That second option seems like a waste of resources, but it may give me less headaches. Surely there are other ltsp users in the same boat right now? Thoughts?

I have a quadcore with 4 GB RAM loaded with K12LTSP 5EL 64-bit. We do run into those issues with Flash being 32-bit only (crashes with nspluginwrapper and 32-bit Flash under 64-bit Firefox, although you can install 32-bit Firefox only) and no 64-bit Java browser plugin being available. You should be able to use 16 GB RAM with the PAE kernel on 32-bit Linux (up to 64 GB according to http://en.wikipedia.org/wiki/Physical_Address_Extension) . Nils Breunese.

This is exactly like herding cats, which, apparently, you have some experience with. I've since realized that even chipping the kids and/or video surveillance won't work. The kids at this school have the option of playing outside if there is an adult out there to supervise. This isn't considered "checking out". The kids really do need to click or swipe something to signify their intention to stay/leave. Since these kids can't be relied on to bring ID badges every day and tattooing bar codes is a wee bit too futuristic, I'm heavily leaning towards fingerprint swipers. Can anyone recommend a linux friendly, affordable, USB, fingerprint reader? One that can read through gloves, mittens, masking tape and layers of assorted jams and jellies? My wife loves the idea of a hand sanitizer station next to the finger print swiper, cut down on colds and flus and track the kids all in one fluid motion. Thank you everyone for your help thinking this through. ck From steven at simplycircus.com Mon Jun 23 21:06:43 2008 From: steven at simplycircus.com (Steven Santos) Date: Mon, 23 Jun 2008 17:06:43 -0400 Subject: [K12OSN] OT - Student Entered Attendance System In-Reply-To: <486002A1.8070000@snarlnet.com> Message-ID: I once worked in an after school program that faced a situation not unlike yours. What they did was give every student what amounted to a poker chip with their name on it, a string through it (to hand around their neck) and a magnet on the back of it (later changed to Velcro). When a student came in in the morning (AM care), they would take the chip off the big board in the outer office. When they entered a room, they would put their chip on the classroom board. When they left to go to another room, they would take the chip off the board, and take it with them to place on the next board. In the case of an emergency, the teacher would just take the board off the classroom wall and have an accurate attendance. Another teacher would take the remaining chips off the main board to know who is not in school, and then they could do a quick comparison to get who is unaccounted for. that system has been in use in that program for over 25 years, and it is still in use today. Sometimes computers are not the best solution to these kind of problems. On the other hand, this an RFID tag embedded in each of the chips and a reader in each of the boards may be another way to accomplish this AND be able to track it... _____ Steven Santos Director, Simply Circus, Inc.

All of the cool new development is happening on ltsp 5. I've been using edubuntu for the last year, and k12ltsp for the 5 years or so before that. I still like redhat based distros better and edubuntu was rough around the edges (at least as of 7.04), but the fedora/centos ltsp5 versions still seem to be in their infancy. I'm just volunteering so I can only do upgrades over the summer. Hopefully I can be back on fedora or centos next summer. The benefit of virtualization is cloning and rolling back when i screw something up, but if I can easily use all the ram in the server without it I'll skip it. Thanks for the input!

I'd suggest to run as much 64bit software as possible to gain full advantage of the server. The 64bit kernel alone is going to make a huge difference - direct memory access, faster script and utilities execution add up very quickly.

If 64-bit Firefox with nspluginwrapper and 32-bit Flash and Java crashes, then why would I want to run it? Because it crashes fast? Firefox is probably the most frequently used app on our LTSP server, but I think we're going to run the 32-bit version because of the problems with plugins. Nils Breunese.

Specifically, Firefox is not included. The basic operating system - kernel, shells, system services - is a good beginning, as it gives you native support for large memory. OO, Gimp, anything you run for many users is going to help a lot when run in 64bit mode. I have one application - DB/C language interpreter, that all the users run, that shows eightfold increase in speed between 32bit and 64bit versions. julius From rob.owens at biochemfluidics.com Tue Jun 24 11:13:42 2008 From: rob.owens at biochemfluidics.com (Rob Owens) Date: Tue, 24 Jun 2008 07:13:42 -0400 Subject: [K12OSN] 64 bit ltsp vs. virtualization In-Reply-To: <48605FAE.9090702@cox.net> References: <485FB7DF.9030908@cox.net> <1214269828.5604.816.camel@merlin.localnetsolutions.com> <48605FAE.9090702@cox.net> Message-ID: <4860D6E6.608@biochemfluidics.com> Luis Montes wrote: > James P.

I believe the way it works is you download the chroot environment for Ubuntu and install it in the /opt tree of a CentOS system. That technically provides an Ubuntu kernel and low-level OS to the thin clients, but then it displays a CentOS system and that's what the users get.

That is very odd. 64-bit does not provide speed. Speed is handled by the clock rating of the core. The bit count determines the size of the addressing area that can be directly accessed for RAM. Internally, the cpu's don't have enough cache to be affected by the bit size. An 8-fold speed increase is tremendous. If this is being run on a multi-core machine, the speed increase may be more related to better threading control in the 64-bit system than the 32-bit (assuming the same machine). The 64/32 bit system like Opterons and Xeons are more efficient in 64-bit mode as it's a single clock tick to fill buffers but it takes an extra tick every 2 fills for 32-bit mode (has to store 2 addresses per fill in 32 bit vs. 1 per 64 - cache writes take a tick). -- James P.

James, it's not that odd - the execution speed is affected by the size of a memory fetch - double per cycle compared to 32bit, machine level moves and compares are also doubled in speed. I was expecting a three- to five-fold increase in speed, because all the programs perform a lot of I/O, but even that was affected - the prefech reads into the I/O cache got faster. julius From jim.c.christiansen at gmail.com Wed Jun 25 19:26:39 2008 From: jim.c.christiansen at gmail.com (Jim Christiansen) Date: Wed, 25 Jun 2008 12:26:39 -0700 Subject: [K12OSN] ltsp-utils public key for k12 install into centos5 Message-ID: <8b88203f0806251226o4344a75do23fc08ff5688303e@mail.gmail.com> Well, I'm stuck...
