I have been trying to find anything that would indicate that it has been done successfully, but have not found anything written.

All of my other > upgrades have been Fedora based versions to newer Fedora versions > since somewhere around version 4 or so. I did CentOS to Fedora on a workstation. I imagine the other way around will yield similar problems. I don't have any notes of what I did and I don't remember the exact versions. The basic idea is the same as with a Fedora to Fedora upgrade via yum, but be prepared for several nasty problems if you go and try it. Your system might not boot on its own afterwards. If you're comfortable using the rescue cd and manually cleaning up rpm messes you could try it, but I'm not going to do it again myself and I consider myself to be a fairly competent rpm ninja. It cost me like a day to clean up the mess. Nils Breunese.

Not to say that it can't be done, but you will likely have to do some phernagling and do a base X install on the laptops and get the wireless working then do the X -query thing to get the server's X up. Then the next thing that will happen to you is bandwidth.one or two will work usably well, but many more than that and the wireless will simply get bogged down to the point of unusability. It might be better to do full installs to the laptops, set up ldap and set home directories on the server. This way, the bulk of the work is done on the computer itself and the only traffic across wireless links will be student's data and Internet traffic. On a side note, I'm betting that the cost of doing 24 or 30 laptops on carts is likely going to be as much or more than desktops in a permanent lab. And, likely, unless you pay extra for the type of charging system that limits the draw on the wall outet (charges a bit slower, but don't load the outlet as bad) you will likely have to upgrade the circuits into the room(s) where the carts will be. We have 12LT/cart and in some of our rooms, you can only plug in one cart at a time if the LTs are drawn down much at all or it throws the breaker.Our carts use the LTs original charging systems. If you plug in one cart and plug the LTs is slowly, it won't toss the breaker, and then you can plug in the other cart and plug them in slowly and if they only have a class period of use on them, it may or may not toss the breaker. Our building is pretty old so your's may have better wiring in it. . . weigh the options before doing either. Both have theie srong and weak points. The portability of the LTs is great. We did 12LTs/cart so if we needed a few here and a few there, we could separate them. Each cart has it's own AP. and each set of LTs only connects to it's respective AP to kinda help with loading issues.

This laptop worked fine using NX Client to connect via its wireless adapter to a K12LTSP server running freenx. I have not attempted to boot the Eee PC directly off the server, though I doubt that would work over a wireless connection anyway.

Thanks for any help/suggestions. > > -Will > > For LTSP of nearly any sort, you really want 100Mbps, Full Duplex, point-to-point (i. e., switched), to each station. Wireless is a shared medium, and even at the fastest speeds, it's not full duplex. The 802.11n spec, which is said to operate--theoretically--at 248Mbps max, has an actual throughput of about 75-100Mbps. And yes, that's shared. Your 802.11g devices might see 40Mbps. Essentially, you'd be putting yourself on a 40-100Mbps half-duplex hub. Not good for LTSP. It will feel about as sluggish as Windows Vista on a 486-33 would. Seriously, don't do it. Your users will immediately demand Windows PC's, incorrectly blaming Linux for the shortcomings of wireless. If wireless is a must, then go with inexpensive Linux thick clients and stick wireless PCI cards in them (Ralink and Realtek wireless are both very Linux-friendly). There are a couple of good options here: 1.) The Everex gPC (that's the famous "Green PC"). It's $199. Available at (at least) Newegg, TigerDirect, and even Wal-Mart Online. Comes with gOS Linux, but should be just fine with any other distro. 2.) ZaReason; they've got a $249 Ubuntu desktop that looks pretty doggone slick. They're at http://www.zareason.com. They'll put any other Free distro on there if you want something besides Ubuntu. --TP _______________________________ Do you GNU ?

We're currently working with a school that will be implementing a new K12LTSP server. The server will be handling roughly 30 clients. The current LTSP servers they have are all Supermicro units with Xeon CPUs. Storage capacity is not incredibly important as all user data is stored on a separate fileserver and mounted via NFS. What would you recommend for specs of the hardware? It should be usable now and be scalable to support future K12LTSP setups. I appreciate any insight you can give. Thank you!

First: This Friday (April 4th, 2008), I'm inaugurating a weekly "Open Source Friday" Web show. We'll cover the news of the week, hopefully have some interesting guests, and let you tell us what you are doing that might be of interest to others. Find the show link at http://www.classroom20wiki.com/live+conversations/. 2pm Pacific / 5pm Eastern / 9pm GMT. If you're into social bookmarking, you might want to join the Diigo group "K12 Open Source" (http://groups.diigo.com/groups/k12-open-source) to bookmark sites and stories that we'll discuss each Friday. Second: The CoSN.org K-12 Open Technologies website has been revamped (Drupal, thanks to Jim Klein!) and is now up with some great content. http://www.k12opentech.org/. Access the CoSN white papers on Open Technologies, including the recent Moodle implementation study. And we have guest bloggers! Recent posts include Jim Klein ("A Few of My Favorite Open Source Desktop Applications"), Solveig Haugland ("Five Principles for a Successful OpenOffice.org Transition"), and Jeff Crawford ("SIF Needs An Open Source Zone Integration Server"). Coming soon: Tom Hoffman, David Thornburg, Randy Orwin, Bryant Patten, and YOU! Want to blog on your successful use of Free and Open Source Software? Reply to this email and let me know. K12OpenTech.org also has a rss news feed for Free and Open Source Software in K-12. See it on the site or subscribe at http://www.diigo.com/rss/user/Stevehargadon/opensource. And the http://www.K12OpenSource.com wiki site has a good set of resources and program list as well. Third: Coming September 25 - 27, the second annual K12 Open Minds conference in beautiful downtown Indanapolis, Indiana. :) Expected to be even bigger and better than last year, K12 Open Minds promises to be the definitive (and only?) *national* conference for Free and Open Source Software in K-12. Last year there wasn't much outreach to K-12 "pioneers" and "stalwarts." Expect better this year. Information will be posted at http://www.k12openminds.com as it becomes available. Fourth: NECC 2008 is coming up soon in San Antonio, TX (June 30 - July 2). NECC is again generously hosting an Open Source Pavilion, where we'll have 50+ computers running Linux and Free and Open Source program, a full speaker series that is in the program, and live demo stations. With sponsorship this year so far from Aspen Learning (http://www.aspenlearning.com) and (hopefully) Red Hat again, we are still looking for additional financial sponsorship (equipment and people transportation!) and for any volunteers to help in the Pavilion during the show. With the recent news that the T + L annual conference (last week in October in Seattle) has asked for an Open Source Pavilion, when added to our good friends at the annual CUE.org show, we now have three major educational technology shows actively showcasing Free and Open Source Software. Have a great rest of the week!

Here's mine, which assumes your 30 users will be using a "fat / full-featured" desktop like GNOME or KDE. - CPU: At least two 64-bit cores, 2GHz each. If you can afford a quad-core CPU, then do so. Either Intel or AMD is fine. - DRAM: Minimum 4GB, preferably 8GB. DRAM is your best friend when it comes to LTSP. - NIC #1: Gig-E on at least the thin client side. If your 30 users are all running TuxType or TuxMath simultaneously, make it two Gig-E NICs ganged together in a MultiLink config. Get decent managed switches that support this if you don't already have them. If DRAM is your best friend, then network speed comes immediately after. - NIC #2: Since you're doing NFS mounts, then I'd go Gig-E on the "school LAN" side as well. Otherwise, 100Mbps is usually fine. - Video: Can be ye olde, slow cheap-o. That said, your clients should have modern video (Intel is good). - Go with hardware RAID 1. SCSI RAID is expensive, but "the bomb" if you can afford it. If not, then get a SATA RAID card, not that fake-y "RAID" junk built into many motherboards (it's software based). I use hardware SATA RAID myself. --TP _______________________________ Do you GNU ? Microsoft Free since 2003 --the ultimate antivirus protection! Tim Nelson wrote: > Hello!

I agree with you. I would prefer the permanent lab. It is not so much an issue about how much power is used, as it is an issue of power outlets in the room. It is against building code to have power strips and extension cords strewn all over the room. We also have the issue of there really not being a room available for technology, that is of adequate size. >>> Rob Owens 04/03/08 9:11 AM >>> Personally I think getting a decent electrical system is a better long-term investment than any computers you can buy.

Test with a differrent NIC. Do you need to provide some authentication for connection? Also how many nics does this this k12 box have. Are you 2x positive you have it plugged in the correct nic and that nic is in working order (i.e you can ping localhost from the external facing IP of the machine?) Can you ping the xp box from a hub, switch or crossover cable? What happens if you statically configure the outward facing IP by stealing the settings from the XP machine. What happens if you put the xp box and the LTSP box on a hub, can they ping each other? What happen if you put the xp box and the ltsp box on a router (perhaps the cable modem is a router?) Can they still ping each other, If it turns out to be an auth problem handle authentication via the router? hth, John On Thu, Apr 3, 2008 at 7:47 AM, Barry Cisna wrote: > Hello List, > > Done a fresh install of K12LTSP/FC6 for an individual for home use for > their kids to use.

To fix that, get a *router* to go between the cable modem and your network. Set the router up to handle the modem and then no matter what you plug in should work. Alternatively, get a cable modem/router (both in one box) and set it up that way. A modem depends on some other device providing the login information. A router will provide that information once set up properly. . . Others may have more info. . .

I think cable companies can restrict the MAC addresses that will get a DHCP address though a cable modem so it the xp box was the first thing that came up it may be a long time before it will give an address to anything else. The quick fix is to use a home NAT router behind the cable modem. Most of them have an option where you can set the visible MAC address on the public side to the one the cablemodem already expects - and you can use more than one computer behind it. Most cablemodems have a web service at 192.168.100.1 (and at least the surfboard models don't even care that you aren't on that subnet yourself), but I don't know if there is enough status info there to help. -- Les Mikesell lesmikesell at gmail.com From julius at turtle.com Thu Apr 3 15:46:23 2008 From: julius at turtle.com (Julius Szelagiewicz) Date: Thu, 3 Apr 2008 11:46:23 -0400 (EDT) Subject: [K12OSN] Cable net connection problem In-Reply-To: <47F4F87A.90704@futuresource.com> Message-ID: On Thu, 3 Apr 2008, Les Mikesell wrote: > Barry Cisna wrote: > > Hello List, > > > > Done a fresh install of K12LTSP/FC6 for an individual for home use for > > their kids to use.

Try a crossover patch cable, try to connect server to xp box, see if you get good connection when you set ip onn both boxes. 2. restricted MAC - make sure you do "ipconfig /release" on the xp box. turn off cable modem, wait 2 minutes. If you still don't have a connection after the cables and nic tested positive, turn off cable modem for the address lease duration + 2 minutes.

The following -should- work, or at least it does for COX. Shutdown the shiny new LTSP server. Turn off the cable modem, then turn it on again. Make sure the only device you have attached is the LTSP server for which you expect to receive an address via DHCP. Turn on the shiny new LTSP server, and the Motorola Surfboard should allow it to communicate. Something to do with MAC addresses and stingy ISPs, as others have mentioned. The modem "pairs" with a particular MAC addy (in your case, sounds like the laptop) and simply refuses to talk to anything else. HTH, -dhbarr.

This latest version includes hardware acceleration which is a great idea for stand alone desktops with average to modern graphics cards. It's a rotten idea on a low powered thin client. Right click a Flash animation and you'll get a menu of options. Choose "Settings" near the bottom. In settings, the first pane (the leftmost) has the option for hardware acceleration. By default, it is checked. Uncheck it and restart your browser. If you've tried this version before and reverted to 9.0.48, you'll see the tab for the display pane but won't be able to access the dialogue.

Of course unsupported apps are hit and miss but if it's Office you want, I think its a better solution than keeping a bunch of windows machines around (and all the maintenance they generate, or paying for MS terminal services. Crossover is really just a commercial version of wine that does a good job of easing the installation and integration part of using wine, plus you get some support too. Basically, you should be able to try a demo version of it out. If memory serves, you can just download it and try it out. If it works for the apps you need, I think its the best solution. The reason that it doesn't win over VMs or RDP (or keeping windows clients) in all cases is that it doesn't have perfect compatibility for all apps. The upside is that it doesn't require the additional resources like VMs or additional machines like RDP. On Apr 3, 2008, at 11:38 PM, Kannan Krishnamurthy wrote: > Hai, > > I am new to linux.

This is emphatically *not* a good idea. Fedora Core 6, the base for K12LTSP 6.0, is no longer supported by the Fedora Project, as of December 2007.

This is good news. :) However, I don't think EL5 (based on FC6) is a good match for K12linux (now being built on FC8-9).

But, I do not want to give up much performance. I've used various desktop machines I've had around for thin clients and they work great. I have noticed that flash performance is related to the power of the thin client. I've got a 3Ghz/1GB Dell setup as a thin client and Flash performance is equal to the desktop performance. Slower thin clients don't work as well on the same LSTP server (could be video card, I suppose). I see on the lists people having problem with flash performance. So, I'm suspecting that memory on the thin client may play a role as well as the video. I'm hoping that something around $200USD or so will get me close to the "sweet spot" for decent hardware.

Seems they have a good selection of product. What you want to look for on any LCD it will say "VESA" compliant. Tiger usually has good multiple pictures of all monitors available. Look at the back for the four mounting screw holes( which matches up with the four screw holes in the Ebox2300). This is the " VESA" compliant peice( I think). Like I said this makes for a very nice " out of sight out of mind" as far as kids fiddling with buttons and trying to jam stuff inside of every open hole,,such as they do with thick clients cdroms,etc.They can simply reach over the top of the monitor to insert a usb stick this way as well if need be for easy access. Most all LCD's have these mounting holes.*but* lots of Dell, Gateway LCD's do not. They have a rounded backside,which will not work. Hope this helps.

Remember that RHEL releases come out every couple of years, so we're looking at at least another year before RHEL (and thus CentOS) 6 comes out. That's a *good* thing, remember, from an actual supportability perspective in the enterprise. And that includes schools. Thus, K12LTSP 5.0EL is far and away the better choice than K12LTSP 6.0. --TP -------------- next part -------------- An HTML attachment was scrubbed...

Sadly, some apps, such as MS Office 2003, aren't supported on Windows 98 (Windows 2000 or later). However, MS Office 2000 and XP are, so Windows 98 emulation works for those. This matters because, as I recall, the Windows 98 emulation was quite good. However, the Windows 2000/XP emulation..."needed work." This may have changed with the latest iteration of CrossOver/WINE. First, I'd be trying out the new OpenOffice.org 2.4.

I have found that HP t5125 works on Edubuntu 7.10 (LTSP5) with this lts.conf. [default] SOUND=True LOCALDEV=True LDM_SERVER="192.168.1.101" LDM_DIRECTX=True X_RAMPERC=80 X_COLOR_DEPTH=16 And for example Fujitsu-Siemens Scenic (P4/256/i845G) do not need any lts.conf on Ubuntu 8.04. http://www.arkki.info/howto/Wiki/LTSP5_64/Nice_Thin_Client.png https://lists.ubuntu.com/archives/edubuntu-users/2008-March/003805.html openSUSE says: "Thin client can be any PC which is PXE boot capable, 128 MB RAM is desired, but you can test lower and see if it works for you." http://en.opensuse.org/LTSP I think ummph is LDM/SSH2 with X.

But, I do not want to give up much performance. I've used various desktop machines I've had around for thin clients and they work great. I have noticed that flash performance is related to the power of the thin client. I've got a 3Ghz/1GB Dell setup as a thin client and Flash performance is equal to the desktop performance. Slower thin clients don't work as well on the same LSTP server (could be video card, I suppose). I see on the lists people having problem with flash performance. So, I'm suspecting that memory on the thin client may play a role as well as the video. I'm hoping that something around $200USD or so will get me close to the "sweet spot" for decent hardware. Anyone happy with the performance of their low-power, small, and quite thin client that can offer suggestions of units to try?

I don't know enough about LTSP 5 to say what makes these clients slower, but you can see this page for verification from an expert that it is true: http://www.disklessworkstations.com/cgi-bin/web/200110.html?id=bY33IUFr I tested it myself on Ubuntu 7.10 with LTSP 5 and found the boot times to be about 2.5 minutes if I remember correctly. I don't have my notes in front of me, but I remember performance being terrible with X over ssh. When I disabled that using DIRECTX=True, it got better but it was still pretty slow for basic things like screen refreshes when minimizing/maximizing/moving a window, or scrolling a spreadsheet. Of course, my requirements might be different than yours. I'd recommend trying one out. They're cheap enough. Just don't buy a ton of them until you've tried it on LTSP 5. Who knows, future versions of LTSP 5 might be less demanding on the thin clients and these could turn out to be pretty good. But so far my experience tells me not to use them for LTSP 5. -Rob From moseley at hank.org Sun Apr 6 17:43:09 2008 From: moseley at hank.org (Bill Moseley) Date: Sun, 6 Apr 2008 10:43:09 -0700 Subject: [K12OSN] A few ~$200 thin clients to try In-Reply-To: <20080406131853.GA29145@junker.owens.net> References: <1207401057.18014.14.camel@localhost.localdomain> <20080405180407.GB24471@junker.owens.net> <20080405204335.GA20661@hank.org> <20080406131853.GA29145@junker.owens.net> Message-ID: <20080406174309.GB25384@hank.org> On Sun, Apr 06, 2008 at 09:18:53AM -0400, Rob Owens wrote: > I tested it myself on Ubuntu 7.10 with LTSP 5 and found the boot > times to be about 2.5 minutes if I remember correctly.

Interesting. I'm asking more out of ignorance just because (when not using SSH) I would think it would be the same X protocol in both versions of LTSP. I know this has been discussed at times before, but I'm also curious why Nomachine's NX technology to reduce bandwidth needs would not be a win?

If you have the default umask of 002, everything should be group rwx already unless it was created by root, and in the RedHat scheme of things everyone has their own group. Just add the teachers to each student's group and make the home directory rwx by group if it isn't already and you'll have most of what you want. The only tricky part is that files created by teachers in a student's directory may not be writable by the student unless the teacher is careful to change groups before creating it or to change group ownership. However, don't count on the students being unable to write to them - some editors will create a new file for changes and rename it to the old name. For this you only need read access to the file and rw to the directory containing it. -- Les Mikesell les at futuresource.com From jamielist at gmail.com Tue Apr 8 04:37:45 2008 From: jamielist at gmail.com (Jamie Lists) Date: Mon, 7 Apr 2008 21:37:45 -0700 Subject: [K12OSN] Dhcp and iMac clients Message-ID: We'd like to do a 1 nic setup for our k12ltsp box and not mess with any vlan stuff.

I've done it here at home with a PMac 5260 and an iMac Orange (Tangerine?). All you have to do is ensure that the proper DHCP-fu ends up in your existing DHCP server. If your existing DHCP server is the standard ISC DHCPD, then just copy the DHCP info from K12LTSP's /etc/dhcpd.conf into your existing one. If it's not ISC DHCPD, though, then it very likely does not support multiple CPU types for thin clients, so you'll have to configure it for x86 thin clients OR Mac clients, i. e., not both. So, you get to choose a thin client architecture...or you get to do VLANs. Personally, I don't know what your objection to VLANs is, as that really is how you should be doing this. Yes, you can do DHCP on different ports, and Chuck Liebow has indicated previously in the list how to do it. It's in the K12OSN archives. Power Macs use neither EtherBoot nor PXE, so you needn't worry about that (they're more like Sun boxes that way). But I'd do DHCP on nonstandard ports only if I had no other choice. --TP _______________________________ Do you GNU ? Microsoft Free since 2003 --the ultimate antivirus protection!

So i don't think that would work. Do you only have one port in the classroom? What I've done in this case is setup the iMacs as a "thick" client, where I do a base install (of Ubuntu Server 6.06 btw) and then install only xserver-xorg and xfonts-base. In rc.local I query the ltsp server and I'm good to go. This route does require the hard drives in your iMacs though. -- Ryan Collins - Technology Coordinator - http://www.kentoncityschools.org/ http://ryancollins.org/wp/ -------------- next part -------------- A non-text attachment was scrubbed...

Here's my experience when I set up a network file storage server for a whole school using Samba a couple years ago: Regular *nix permissions are kinda limiting. The only reasonable way to use "other" is if something should be world-readable, which isn't usually the case so mostly those permissions are irrelevant. "user" obviously has to be the owner/creator of the file. That just leaves "group", and there can only be one of them. A reasonable group is something like 'all adults'. Thus with ownership and permissions joestudent facultyandstaff -rwxrwx--- you get a file that can be accessed both by the student and by all adults. But the limitation of just one owner and one group is hard to extend much further. [You might want to have several groups ('faculty that teach 2009', 'class of 2010' etc.). You might even want these groups to overlap somewhat (ex: Mr. Teacher belongs to both the 'faculty that teach 2009' and 'faculty that teach 2010' groups).] For most things finer than 'one student' and 'all faculty' you'll need Posix ACLs. They extend *nix file permissions to allow more than one "owner" and more than one "group". As just one owner and one group was recognized as very limiting long long ago, there are a couple tricks in *nix that modify the scheme slightly. One is the "setgid" bit, which if set on a directory on most *nix systems means force the group ownership of all files created inside that directory to be the same as the directory itself. The other is the "sticky" bit, which if set on non-executable files on most *nix systems means the file can be deleted only by its owner/creator, regardless of any other permissions on either the file or its containing directory. I found traditional *nix permissions too limiting even for a fairly simple student file storage system, in my case because I wanted to subdivide the teachers into several possibly overlapping groups (a desire for 'class' directories would also seem to be impossible with just traditional *nix permissions). So I enabled Posix ACLs on the filesystem where all the Samba data was stored, and manipulated them as necessary (often by writing custom shell scripts). You need to have Posix ACLs compiled into your kernel. You need to have an extra parameter on the file system line in /etc/fstab. And you need to use the ACL tools every time a file is created. I found Samba wouldn't interfere with this approach ...but it wouldn't help a whole lot either. A couple gotchas tripped me up: 1) Samba tries so hard to provide the same semantics as Windows that it will even fiddle with Posix ACL inheritance in a few cases. The result is that what you get when you create files via *nix (ex: touch) is _not_ exactly the same as what you get when you create files via Samba. There's no way to entirely "fix" this (after all most don't see it as a problem:-). There are a couple parameters in the Samba configuration that will reduce this problem from being even worse ...but they won't eliminate it entirely no matter how they're set. 2) In the Samba world the term "ACL" means "_Windows_ ACLs". That's all most folks care about or know about. If you ask a question about "ACLs" it's likely the answer will just be puzzling and the responder won't even realize you were talking about something different. I took the approach of entirely abandoning any attempt to use or simulate Windows ACLs, and did everything with Posix ACLs. Judging from the responses I got, this approach was quite unusual. In fact I never managed to find anybody else who had done the same thing and was ready to talk about it. With the possibility of more than one "owner" and more than one "group", I could do things like: rw by creator, r by 'other studends of the class of nnnn', rw by 'teachers of the class of nnnn', r by 'all teachers', r by 'all admins', rw by 'IT staff'. With Posix ACLs, I also set up "drop boxes" for submitting homework (can put files in, but can't read other files or delete any files), "public squares" for several students to collaborate, "materials" areas (writable only by the teacher, readable by everybody), and "help me" areas (writable by the student and the teacher, but nobody else). And I set up folders not only for each student but also for each classroom period. Some of these were a little tricky even with Posix ACLs. For example both making the "drop box" behave exactly correctly _and_ allowing deletion through Samba of work after it had been graded didn't work quite right for months. I eventually got the rest of the drop box behavior to work right by removing file deletetion altogether from the Samba side and handling file deletion separately from the *nix side with a 'cron' job. Most *nix tools (for example the `cp` command) support Posix ACLs. Backup however was a problem for me. Neither the regular `tar` nor the then-current release of `rsync` supported Posix ACLs. I had to get `star`, and a non-standard version of `rsync` that supported Posix ACLs. Posix ACL support has since been rolled into the very latest versions of `rsync`. But those versions aren't included in any distros yet so you may have to fetch and/or build a special version anyway. In summary, it seems to me your options are: 1) KIVSS (Keep It VERY Simple Stupid) 2) Posix ACLs - always keeping in mind that you may have to be clever and/or override the default action of the system to get what you want 3) Windows ACLs (no experience here) good luck! -Chuck Kollars ____________________________________________________________________________________ You rock.

Don't forget that every path element has its own set of permissions. You can put files with 'other' permissions under directories permitting only certain groups, or 2 levels of directories that permit different groups so only the overlapping members get through. > "user" > obviously has to be the owner/creator of the file. > That just leaves "group", and there can only be one of > them. But every user gets his own group by default in the RedHat scheme, and files permit group access.

Or make appropriate groups. If all teachers can access all students' files, that's pretty straightforward. If only a student's own teachers should access his files you have a little more work. You don't have a problem unless you want a student to be able to subdivide his files, giving only the relevant teacher access to each file. > I found traditional *nix permissions too limiting even > for a fairly simple student file storage system, in my > case because I wanted to subdivide the teachers into > several possibly overlapping groups (a desire for > 'class' directories would also seem to be impossible > with just traditional *nix permissions). What limit did you find for the number of possible groups? The usual problem on the unix side is that new files are created in the user's primary group and may not be accessible by the intended other group unless someone pays attention and either changes to the group or changes the group ownership of the file. > I found Samba wouldn't interfere with this approach > ...but it wouldn't help a whole lot either. With samba you have the option to limit access to members of a group and to force creation of new files with a certain user and/or group ownership so users don't have to pay attention. > With Posix ACLs, I also set up "drop boxes" for > submitting homework (can put files in, but can't read > other files or delete any files), Can't you get that with a group or other writable directory, with sticky bit set, owned by the teacher who is also a group member of the students who will submit? > "public squares" for > several students to collaborate, Group (perhaps a unique group) or other writable, sticky bit set like /tmp if you want to restrict deletions to owners. > "materials" areas > (writable only by the teacher, readable by everybody), Obvious. > and "help me" areas (writable by the student and the > teacher, but nobody else).

Laptops require power, too. And unlike cheap desktops, laptops will require new batteries every year or so. So there is a constant repair process of $50/year/machine. Laptop carts are mostly designed to park laptops when not in use. If they aren't in use, why have them at all? Save yourself the headache and buy designed thin clients machines (small, lo cost, no moving parts, no Microsoft tax) and upgrade the power with the savings in not getting M$ Office (and all the upgrades it takes to run it in both software and hardware). Thin clients can use wireless but not K12LTSP in the default setup. To date, there is no way to do PXE boot over a wireless network so don't plan on going that route. You can use a flash drive for a base Linux system that supports wireless and then remote access X for the real stuff but you WILL have bandwidth issues. You could do the whole freeNX thing and do a compressed data stream but you will still have network security issues. Do you _really_ want kids wandering around with the computers? The Asus EeePC can connect to a remote X session just fine. The battery issue will still get you in about a year. Wireless is a myth. All electrical devices are tethered by a wire at some point. Wires are cheap and easy to use and maintain. A 24 port switch is under $100. You can't GET 20 students using a wireless access point with any usable bandwidth for less than $500. 802.11g is 51Mb/s. The cheap wire connections are 100Mb/s and don't care about the concrete walls dropping you bandwidth down to 2Mb/s (split between 12 people!). Wireless will not make heroes!

The current LTSP servers they have are all Supermicro units with Xeon CPUs. Storage capacity is not incredibly important as all user data is stored on a separate fileserver and mounted via NFS.

If you need to go *really* cheap, then get some older Pentium II or III computers that PXE-boot, and simply pull out the hard drives. Companies are *dying* to get rid of these and will happily "unload" them to you. HP Vectra VL400's are good choices. Then, gradually replace them with MicroClients or something similar as time goes on. --TP _______________________________ Do you GNU ? Microsoft Free since 2003 --the ultimate antivirus protection!

Simply add in an ACL to stop any output from the server's outside IP address on those specific ports.

We're recently seeing infestations on our Windows boxes by Trojans that talk on TCP port 6667. We've had to ask our on-site technicians to re-image several machines at several schools already.

Very bad for LTSP. The above is why wireless doesn't scale well. Plus you have the security issues. Sure you CAN try to scale it, but getting the "equivalent" performance to a 100mbps wired network means multiple high end 802.11N access points. You need WPA, probably with a RADIUS server, and enabling that usually entails a performance hit on most access points. Hence why you need so many, in addition to the fact that wireless is a shared medium and performance drops as you mover further away. IMHO, the best setup for a school is 6-7 clients per room (plus one for the teacher) and lab(s) for when you need one to one. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (Darwin) iEYEARECAAYFAkf8swoACgkQxWV7OPa/g5EePACfd1NsWL7kHD8XAmCSJU30moAO 6vEAn2iuONWAKbUa5UCS5F51dFGt+2Tq =jRr5 -----END PGP SIGNATURE----- From balmquist at mindfirestudios.com Wed Apr 9 12:17:24 2008 From: balmquist at mindfirestudios.com (Almquist Burke) Date: Wed, 9 Apr 2008 07:17:24 -0500 Subject: [K12OSN] Permissions for students and teachers In-Reply-To: <47FBFDB9.50801@futuresource.com> References: <656107.17590.qm@web65602.mail.ac4.yahoo.com> <47FBFDB9.50801@futuresource.com> Message-ID: -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 It's been my experience that the only real limitations with UNIX permissions is when you want to have one group to have read-write access, one group to have read only access, and everyone else not to have any access at all.

If this applies to everything in a directory, make the directory and files group rw and other r (+x for the directory) owned by the group with write access, and make a directory above that group rx for the group with read access, no access for other. Include all the members of the group with write access in the one with read access. Only the combined group members can get through the upper directory, and the ones that aren't in the rw group will be constrained by 'other' permissions on the lower directory/files. -- Les Mikesell lesmikesell at gmail.com From peter at scheie.homedns.org Wed Apr 9 13:09:30 2008 From: peter at scheie.homedns.org (Peter Scheie) Date: Wed, 09 Apr 2008 08:09:30 -0500 Subject: [K12OSN] Newbie question In-Reply-To: References: Message-ID: <47FCC00A.8050602@scheie.homedns.org> As Nils said, K12LTSP is a version of Linux that has the LTSP parts already included.

I'm curious as to how managing ACLs would be any different.

I haven't used Posix ACLs, but what I've seen people do with Windows ACLs has been much harder to maintain than group memberships because they can be completely arbitrary and tend to be attached to arbitrary sets of files. When things change, they usually try to do recursive changes on directories which won't work because the settings were per-file, not organized the same all the way down. -- Les Mikesell lesmikesell at gmail.com From nils at breun.nl Wed Apr 9 18:37:32 2008 From: nils at breun.nl (Nils Breunese) Date: Wed, 9 Apr 2008 20:37:32 +0200 Subject: [K12OSN] Need help with a Python Upgrade on FC6 In-Reply-To: References: Message-ID: <12080F3D-C5E7-40D9-A8F7-B02A7FE4CBDB@breun.nl> Robert Arkiletian wrote: > 2008/4/8 Nick Fenger : >> >> My question: >> >> Do I run them both?

And HA would not be too hard, too, using something like http://www.backhand.org/wackamole/ to share a pool of IPs across a cluster of LTSP servers. Need a fast switch for the pool, of course. Granted, if a machine fails a client would need a reboot, but dhcpd would not need to be reconfigured. Kind of handy to be able to just plug in a new server and have it start working and sharing the load. The risk is a machine or two might die overnight and you would never know it was down. ;) Of course, one of the benefits of LTSP is to not have too many machines to manage. -- Bill Moseley moseley at hank.org From robark at gmail.com Wed Apr 9 18:57:33 2008 From: robark at gmail.com (Robert Arkiletian) Date: Wed, 9 Apr 2008 11:57:33 -0700 Subject: [K12OSN] Need help with a Python Upgrade on FC6 In-Reply-To: <12080F3D-C5E7-40D9-A8F7-B02A7FE4CBDB@breun.nl> References: <12080F3D-C5E7-40D9-A8F7-B02A7FE4CBDB@breun.nl> Message-ID: On Wed, Apr 9, 2008 at 11:37 AM, Nils Breunese wrote: > > > > I guess you should be able to install Python 2.5 from source in /usr/local > which won't mess with the OS packages.

Yes and you would have to ensure that /usr was before /usr/local in the PATH for the OS to find python.(I think that behavior is default) In addition students would not be able to type python myprogram.py but rather the full path to the newer version. -- 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 jkinney at localnetsolutions.com Thu Apr 10 00:24:38 2008 From: jkinney at localnetsolutions.com (James P.

Since the winders machines are passing traffic _through_ the Linux system using NAT, add a rule allows SNAT from machines For specific port connections only and bit-bucket the rest.

For the other end (K12LTSP as host OS), I can testify that it works great. We had a training project that absolutely needed Windows+IE, and just as absolutely had to happen yesterday. I set up K12LTSP and 4-5 old P3's, setup VMWare server on the K12LTSP box, and allowed all the users to run the VMWare server console. Windows+IE in the VMs, and everything was nice and snappy. -dhbarr.

It seems my experience is in danger of being completely misunderstood, so please permit me to try once more to state my point: I needed --and now have-- a system that requires _zero_ maintenance of permissions/groups/ACLs after the system was launched, so it's irrelevant whether such maintenance would be easy or hard because it's not done at all. The way I set up a working system within the constraint of requiring zero maintenance of permissions after launch was with Posix ACLs (in fact I don't know how to do it another way, and I even suspect that just vanilla *nix permissions are insufficient for detailed student/teacher file storage within this constraint). If you don't have the requirement/constraint of zero maintenance of permissions after launch, my experience probably doesn't apply to your situation. thanks! -Chuck Kollars __________________________________________________ Do You Yahoo!?

Message-ID: <83db5b960804101303l6be49c58gd2c0dfc2ed1656c7@mail.gmail.com> Hi, Any suggestions will be appreciated. I have some Visara e300 eTerm thin clients which have an earphone jack or audio out. I can not get sound to work under LTSP with these boxes. Everything else works beautifully. I can PXE boot them from Edubuntu 7.10 and Centos K12LTSP 5.0 EL. The clients come with WIN CE 4.2 loaded on the 32 meg DOC and sound works when booted into WIN CE. A chip on the board is marked AD1881A, which I assume is the sound chip Analog Devices 1881A or SoundMax Integrated Digital Audio. LTSP does not auto recognize any sound device when loading. I have tried forcing a loading of the following modules in lts.conf: snd-ac97-codec snd-intel8x0 snd-intel8x0m snd-ad1889 Still, no sound or no /dev/dsp. Is there any hope of getting sound on these thin clients? Any conclusions from those of you much wiser than me will be greatly appreciated.

Icewm + Kdesktop) I use separate server (dualxeon with PCI-X) for /home over NFS - 3ware SATA2 RAID 5 + Gbit LAN. (3 LTSP servers behind). Main bottleneck is communication between RAM and CPU. I removed one of the dualchannel memory and server's speed reduced dramatically. There is even no need for quadcore CPU, because usually clients in normal office environment do not use such CPU critical apps. Only reason for Quadcore is in case, when one of processes "goes mad" and uses 99% of core. (sometimes I saw it on 32bit FC6) Increasing number of clients is not rasonable, because increasing CPU or RAM do not remove or rise bottleneck. Also, 32bit kernel can use on modern C2D motherboards only 3.2GB of RAM. 64bit kernel uses all memory. Byt, I repeat, usually there is no need for more than 3GB, because 15 concurrent clients use approximately 2-2.6GB of RAM. Beginning of 2.4G (with 3GB of RAM), FC6 start swapping. (maybe modern C2D or C2Q server motherboards can handle over 3.2GB RAM on 32bit system) Now (March 2008) I use K12 EL5 64bit (centos 5) on C2D E6550 with 4GB RAM - 15 concurrent clients. I'm happy!

I think AMD's on-chip memory controller is better than Intel's off-chip bottleneck. The important thing for a good terminal server is plenty of RAM. Fortunately, prices are low this year. You want a minimum of 50 MB per user + some for the OS and sercices. This year I run my lab of 24 seats with 2 gB just fine with an old Xeon. It is maxed out with 100 mbits/s (my bottleneck) because my new networking stuff has not arrived yet. It is a great time to use LTSP with the prices of gigabit/CPU/RAM/storage all very low. -------------- next part -------------- An HTML attachment was scrubbed...

The community is plaque with a high crime rate, high un-employment rate, the whole package :-(. Its also a superb example of the digital divide. The project is currently ongoing, where children and adults are given mathematics and English classes twice per week. We were talking to the organizer , and he mention that he would love to be able to exposed them to computers, but he found the pricing prohibitive and it cost a fortune and he really not a techy. I realized that he was thinking windows and thick clients. Having hanged out on this forum for while , It was easy for me to realized that thin thin clients would be an ideal for a situation like this.That's when inevitable happened,I volunteered. and of course inevitable events comes in groups , so they also asked me to write the proposal and design the lab, and be the technical lead and all other things technical :-0. I am really excited about this project, but i suck at writing proposals , i thought, that's where you guys might be able to help, so here goes my cry for help. So if any of you guys have a Proposal for the development of Thin client lab hanging around, can a i get a copy , i would use it as starting point for my proposal, i am also open to any other help, you guys can give ,technical suggestions , prayer , a joke :-) etc. Thanks in advance guys. In the mean time i am going to be doing some googling, going to get me some case studies, I am in the windows country, I doubt they will wants us linux types around dem parts here, its highly likely, that i may be coming up against a few windows slingers,that may want to throw in a few thick clients and a few "free" windows licences . Thanks again guys.

Use K12LTSP 5.0EL. Fedora Core 6, on which it's based, is no longer supported since December 2007, and you're asking to get compromised if you continue using it. K12LTSP 5.0EL, on the other hand, will be supported until the year 2014, since it's based on CentOS 5. What I would do if I were you is download the DVD image. It's available here, and it looks like there is now also a torrent. http://k12ltsp.org/mediawiki/index.php/DownLoad --TP _______________________________ Do you GNU ?

Is it only the thin clients that take minutes during heavy network load? Also, are you running the "classic" two-NIC LTSP, or are you doing single-NIC? If you're running two-NIC, then load on the main LAN shouldn't at all affect the thin clients getting addresses. --TP _______________________________ Do you GNU ?

(http://writer.zoho.com/public/dtrask/FOSSED-2008-Registration-Governors-Academy) What makes FOSSED different from any other tech conference? Many education technology conferences last only one or two days and are generally "day conferences". FOSSED is different. We offer 3 days of "immersion" and hands on education. You get a chance to experience what you're learning. Learning about Moodle? We set up and create Moodle accounts that you can use long after the conference. You get to learn at the conference and continue learning long after you've left. Learning how to build a server? Great! We encourage you to bring it to FOSSED and we'll help you leave with a fully configured server. Probably the best part about FOSSED is what goes on outside of the sessions. Since we basically eat together, attend class together, and relax together you really get a chance to get involved in discussions that often foster ideas that you can use later in your own school or classroom. Personally? I've learned more from talking with my colleagues at FOSSED and bouncing some of my ideas off them....then I've learned in any other technology conference. Hands on, time to try things out, camaraderie, and a chance to talk with others are just some of the things that make FOSSED a unique experience.

If using managed switches I would guess the spanning tree piece needs to be turned off on all of these managed switches. When you run into this at a given time,look as each client boots up( it will be the first few lines) to see what IP , subnet, dhcp server #'s are showing,then as it boots farther along make sure you don't see a different number( shortly before the video configuration starts coming across) for the dhcp & or nfs server . I wonder if you have a second dhcp server in your lan somewere. This happened to me many moons ago, probably first version of k12ltsp ( when i had no clue what I should be seeing) and sometimes the clients would boot fine,and the next day they would do what you are explaining,or they would end up kernel panicing. Another thing you could take a laptop at peak usage time, and "walk the halls" to each switch, plug in, and see if the laptop hangs bigtime trying to get an ip address. This might narrow down/isolate which switch is the problem area. Good Luck.

Mac OS X uses PDF for screen rendering, so it's conceivable that you could blow up a screenshot and not end up with artifacts, but I doubt that's possible on a pixel-based screen rendering system. I actually a little surprised it works on the Mac.

So couldn't you just up the screen resolution for her shots? AFAIK all screenshot tools just use the screen resolution. I wouldn't know how you would be able to take a screenshot that has a better resolution than the screen. Maybe the magic is in the lossy compression used to save the file or a different resize algorithm used? Nils Breunese.

Right, it's a function of the image viewer's interpolation/smoothing of the captured image. For example, Eye of GNOME 2.22 seems to do a good job of smoothing a zoomed image: http://files.mesd.k12.or.us/~dyoung/smooth.png -- Dan Young Multnomah ESD - Technology Services 503-257-1562 From rob.owens at biochemfluidics.com Mon Apr 14 15:23:16 2008 From: rob.owens at biochemfluidics.com (Rob Owens) Date: Mon, 14 Apr 2008 11:23:16 -0400 Subject: [K12OSN] OT: Screen capture software In-Reply-To: References: Message-ID: <480376E4.5020905@biochemfluidics.com> You can use Gimp to get screenshots, and it lets you set a time delay so you have time to open menus and stuff.

The heavy flash sites that the district has chosen for training and tech applications, and the tests mandated by the State are making the thin client option a hard choice. Our new CTO wants true thin clients, but some of the MS specific apps can't deliver via Remote Terminal Services, so now we are looking into "fat" thin clients (!) with CE embedded, so part of the processing is done by the client, leaving some room for other services... We've even coined the term "yahooligan's syndrome"... see how many clients you can run from a server before nobody goes anywhere. My brief saga is a call for experiences and solutions the members of the list have experienced. If there is a way to run 30 sessions of Learning.com's EasyTech for instance from one of our servers, I'd love to know how the system was tweaked/set up. I've suggested small clusters of PCs and 3/4 thin clients as a possibility, but I don't seem to be making much progress. The Dark Side looms! On a related matter, does anybody know if symbio-technologies is still around? Several emails I've sent have gone unanswered - I hope they are working on solutions to my problems.

Lots of people don't look at the whole picture of what is wanting to be accomplished in the techie world. I don't care if you buy all of the latest greatest full blown Pc's from Michael Dell if you get x number of people parked in a lab watching full screen United Streaming video stuff it is going to get slow in time. It's that simple. Unless your school has a T3 or DS3 net connection( which I would doubt hardly anyone here has), this is going to be the scenario for any multimedia arrangement.One cluggy work around is to pull whatever videos are wanting to be seen to your local server then point each student to the local server. This is pretty unpractical,though.Most videos are streamed to let Joe Schmoe at home watch them ,not 30 people at one time. one needs to learn how to "tame down" overkill videos,to be viewed by a room full of PC's. I understand your predeciment of the old die hards wanting to use MS ,"cause everyone else does":(..OK I've gripped enough:)...

It also works very well in a business situation. You made a good choice. One thing before we get started: you should plan ASAP to "upgrade" to K12LTSP 5.0EL, as Fedora Core 6 (the basis of K12LTSP 6.0.0) hasn't received security updates since December 2007. You are thus vulnerable to getting hacked. CentOS 5, the basis of K12LTSP 5.0EL, on the other hand, will be supported to the year 2014. Turns out that CentOS 5 looks and acts virtually identical to Fedora Core 6, so your users won't experience user-interface disruption. There are two ways to install what you're after. There's the command line way, and there's the GUI way. To install the kernel source on my system (K12LTSP 4.2EL) from the command line, I did this, as root: yum install kernel-devel which should also install the header files. The GUI way is to fire up the "Add/Remove Programs" application and install the "kernel-devel" package. --TP _______________________________ Do you GNU ?

Since the State firewall/proxy is filtering content and blocking almost every possible site with questionable content, it is a risk I'll accept until the issues with .124 (slowness and sound) are sorted out.

Message-ID: <1208654787.2606.12.camel@localhost.localdomain> Hello List, Just posting this as I hope it may help someone else out that is getting the " Header is not complete" message all the time,when using yum from terminal to try and pull in updates & or packages. After much wrangling with my first install of 5EL, I'm still not sure what is a tad wonky with my server setup. At school i kept getting this error:" Header is not complete". So,, stupid me I drag the server to home to see if I get different results, which I did. I could then download packages, but it seems the repos,were not all pointed to the others. Spent waaaayy too much time trying to get all of the multimedia stuff installed! After some manual modifying of the repos,I got all the extras installed. Possibly the gig nic/(Broadcom),may have bigger chunks trying to download,than what our school's border firewall, is wanting to allow? Don't know. The other K12LTSP servers still download yum stuff fine. Ill paste a nice trace command,that I used to determine that I was not talking to the yum repo servers: Q. 5: I get an "[Errno -1] Header is not complete." error from yum - what the heck is going on? A. It's probably a proxy somewhere between you and the repository. You may not think that a proxy is in the way even though it really is. You can try doing a "trace" with this command: echo -e "TRACE / HTTP/1.1\nHost: yum-server.example.com\n\n" | nc yum-server.example.com 80 Which should give you some more information about the network between you and the repository. Also, be sure to replace yum-server.example.com with whatever your yum repository server is. Another diagnosis step is to get the box off of that network (not always entirely possible, but port forwarding, VPN, or dialup can simulate the experience) and see if you still have the problem. The solutions to this problem are: 1. Get your proxy software/firmware updated so that it properly implements HTTP 1.1 2. Use an FTP repository, where byte ranges are more commonly supported by the proxy 3. Create a local mirror with rsync and then point your yum.conf to that local mirror 4. Don't use yum Take Care, Barry Cisna From brcisna at eazylivin.net Sun Apr 20 01:33:02 2008 From: brcisna at eazylivin.net (Barry Cisna) Date: Sat, 19 Apr 2008 20:33:02 -0500 Subject: [K12OSN] Widescreen LCD on clients Message-ID: <1208655182.2606.18.camel@localhost.localdomain> Hi Jim, This does not help you out any but our school bought about 50 widescreens 19"( on sale tigerdirect-:) ) at the beginning of this school year and they ALL have the stretched look to them ,regardless what PC or thin client they are connected to.

The basic screen settings in xorg.conf need to be tweaked. For instance my widescreen laptop showed similar stretched look is I use 1200x960 resolution but is corrected with 1200x800 Unfortunately I do not have anything more than this to help out further. -- Regards, Sudev Barar Read http://blog.sudev.in for topics ranging from here to there.

I also have a Keyboard, Monitor and Mouse hooked up on it via a KVM switch, you might consider getting one of those. The belkin one (IIRC) was pretty cheap and worked really well. I've found each method to have it's advantages under different circumstances, but I've never become the CLI master. If you've got a good handle on the CLI, SSH could/should be all you need. ck From jschubert at shaw.ca Tue Apr 22 23:34:54 2008 From: jschubert at shaw.ca (Jeremy Schubert) Date: Tue, 22 Apr 2008 17:34:54 -0600 Subject: [K12OSN] logging in as root In-Reply-To: <480E38B6.2080307@snarlnet.com> References: <480E38B6.2080307@snarlnet.com> Message-ID: <000701c8a4d1$77a79290$66f6b7b0$@ca> Ok, I`ve got a headless server going now.

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. -- Les Mikesell lesmikesell at gmail.com From solveig at comcast.net Wed Apr 23 13:10:19 2008 From: solveig at comcast.net (solveig at comcast.net) Date: Wed, 23 Apr 2008 13:10:19 +0000 Subject: [K12OSN] Free OpenOffice.org seminar in the Charlotte, NC area Message-ID: <042320081310.1427.480F353B000CC4D300000593220073407609070A9004019C@comcast.net> Hi, My name is Solveig Haugland, and I do OpenOffice.org and StarOffice training and consulting.

The secret is that you don't need any client software. Set your clients to boot from the network and off you go. If you just installed K12LTSP 6, I recommend starting over and installing K12LTSP 5EL instead since this release *is* supported and looks and feels almost identical. Nils Breunese.

I bet the screensaver selection will show up. it sounds like maybe whatever user you are logged in as, has hosed this users home settings? if this works do the following for the user in question in a terminal on the server.: ../opt/ltsp/templates/k12linux/reset-default-desktop usernoscreensaver This will reset this users desktop and hopefully "see" the screensaver list now.

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. -- Les Mikesell lesmikesell at gmail.com _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn For more info see From Marc.Fromm at wwu.edu Mon Apr 28 21:33:09 2008 From: Marc.Fromm at wwu.edu (Marc Fromm) Date: Mon, 28 Apr 2008 14:33:09 -0700 Subject: [K12OSN] screen savers In-Reply-To: <1209414805.12325.10.camel@localhost.localdomain> References: <1209414805.12325.10.camel@localhost.localdomain> Message-ID: <81FEAB8CDDC62B42B6E8AA258228BC88053A0AC7@EVS2.univ.dir.wwu.edu> I created a new user and logged in as the new user on one of the terminals. I clicked on Desktop Preferences Screensaver. The XScreensaver windows opens, but no screensavers are available to select. The box that would normally list them is blank. I checked the files in the home directory of a terminal/user that has screen savers available. There is a file called .xscreensaver. In that file there is a "programs" section with the names of the screen savers that appear in the selection box. The terminal/user that doesn't have any screen savers to select has the .xscreensaver file, but the "program" section has no files listed. If I add a screen saver file name to the "program" area in the .xscreensaver file, that screen saver is then in the list on the terminal/user that previously had no screen savers. It looks like when a new user logs in, the .xscreensaver file that gets created in the user's home directory is not getting the list of available screen savers.

Jim As long as samba is running and the windows login name is the same as the linux name - or you are using samba as the domain controller for windows it should just work. That is, each windows user will only see the corresponding home directory. If you also want access to linux applications while running windows you can use the NX client with freenx, cygwin X, or vnc. -- Les Mikesell les at futuresource.com From Marc.Fromm at wwu.edu Tue Apr 29 23:46:45 2008 From: Marc.Fromm at wwu.edu (Marc Fromm) Date: Tue, 29 Apr 2008 16:46:45 -0700 Subject: [K12OSN] configure instructions Message-ID: <81FEAB8CDDC62B42B6E8AA258228BC88053A12FD@EVS2.univ.dir.wwu.edu> I tried to use these instructions to configure ltsp http://ltsp.mirrors.tds.net/pub/ltsp/docs/ltsp-4.1-en.html#AEN21 It appears significant details are missing on how to configure all the files.

K12LTSP is a distribution that should 'just work' out of the box. No need to configure anything. What did you try to configure about LTSP? Nils Breunese.

Jim Les already mentioned Samba, which would be my first choice as well. But if you can't, then you might consider trying out the latest KDE 4.0 binaries for MS Windows and use Konqueror to "fish://" to your Linux homedirs. While I've not tried it on MS Windows, I do this from Linux thick client boxes all the time to Linux file servers. The syntax is this, in Konqueror: fish://servername IP addresses also work in place of "servername". To the end user, it looks like everything's local, just like any other Konqueror window. --TP From microman at cmosnetworks.com Wed Apr 30 04:25:59 2008 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Wed, 30 Apr 2008 00:25:59 -0400 Subject: [K12OSN] Finally need to logon and access homes from windows In-Reply-To: <8b88203f0804291201y1d33652atd48879126082e0a6@mail.gmail.com> References: <8b88203f0804291201y1d33652atd48879126082e0a6@mail.gmail.com> Message-ID: <4817F4D7.10108@cmosnetworks.com> You want to go to K12LTSP 5EL anyway for a whole host of other reasons.

I don't think setting that up will be any easier or harder on Centos than Fedora 5 or 6; setting Samba up is easy on any of them. So, I wouldn't change your existing systems for that, at least not this late in the school year. There are other reasons to upgrade, chiefly the fact that support updates are no longer being produced for Fedora 5 & 6. But that can wait until summer.

Now, we are researching what type of hardware to use, what software, and thin-clients or not. I have used k12ltsp successfully in the past. We use Windows 2003 Server with a domain here in the school. My question is: I've come across this Linux system called Userful. It works likes terminal services, except that the setup is a bit different; monitors are connected directly to the server, along with usb mice and keyboards. The server would have 20+ ports for video. Has anybody used this system?

The simplest if not least expensive is to use switches that support spanning tree protocol, end enable it. There is a small packet delay penalty, but it is usually negligible. All my HP Procurve switches have STP set and have no problem with looped cabling. since this happens in rooms served by a single cat5 wire, local STP is really crucial. If only a big upstream switch has this capability, it will stop all traffic from the affected room. julius From Marc.Fromm at wwu.edu Wed Apr 30 21:55:11 2008 From: Marc.Fromm at wwu.edu (Marc Fromm) Date: Wed, 30 Apr 2008 14:55:11 -0700 Subject: [K12OSN] configure instructions In-Reply-To: <590C489D-CEF3-4B01-9CC3-05036AF7D695@breun.nl> References: <81FEAB8CDDC62B42B6E8AA258228BC88053A12FD@EVS2.univ.dir.wwu.edu> <590C489D-CEF3-4B01-9CC3-05036AF7D695@breun.nl> Message-ID: <81FEAB8CDDC62B42B6E8AA258228BC88053F6D0D@EVS2.univ.dir.wwu.edu> I tried to configure the required files that will allow a box to find and boot from the LTSP server.
