FreeNX just lets you run a remote linux desktop efficiently. The real issue here is that you'll need a windows license for every instance of windows, even under VMware, and a client license for every rdesktop connection to it.

Linux isn't Windows nor Mac OS X. Those systems are exorbitantly expensive, both to purchase and maintain, such that nearly all schools have at best only a few computer labs, and students get less than an hour per week on the computer. Rather than trying to recreate the Windows experience--which you can't because, as just mentioned, it's way too expensive--use LTSP's advantage, which is that it drives computing costs WAY down, to provide computer access everywhere. What students need in a computer 90% of the time is a web browser and a word processor. Relegate other specialized apps to the lab for those infrequent times when they are actually needed.

We now have a single K12LTSP server (dual processor Xeon 64-bit with 8 GB RAM, K12LTSP 6.0) beaming out on a 1 gig switch to a total of 4 different labs: a 10-station lab, an 18-station lab, a 7-station lab, and a 2-station lab. They all have remote desktop (alt-F4) to a terminal server "just in case". And miraculously they now all have Flash (nspluginwrapper) and sound (and even better, flash WITH sound! - pulseaudio). User logons seamlessly connect with Active Directory, including a desktop link to their mounted windows document folders. It's awesome, and it smokes: very fast and clean user experience. Our clients are a hodge-podge, the very best ones being a bunch of PIII IBM Netvistas. Excellent machines, and so easy to configure for PXE it's ridiculous. I also have a bunch of old IBM P1 machines that do fine, except they are a little slow and the video craps out on them now and then. SO that's where I'm at. We have another 20 Netvistas and about 10 Dell GX110 PIIIs (also very capable machines) waiting to find a home. Thanks again for all the help you folks provided back in December and January when I was getting things up and running. If there is anyone else nearby with or thinking of starting a K12LTSP lab, drop me a line.

I wrote my own wiki entry. The page you named was none too helpful, but at least it gave me the idea of trying pulseaudio. I hope that my own entry is at least a little better, but I haven't had any feedback on it and I can't yet say whether it has any errors. It uses yum instead of the rpm stuff. You might have to enable additional repositories, I've forgotten. See http://www.k12ltsp.org/mediawiki/index.php/Getting_flash_to_work_with_sound_in_64_bit_platform This works for K12LTSP 6.0 64-bit, but I would think you could adapt the bottom half for 32-bit and ignore the top half. Please let me know if it works for you. It's pretty straightforward once you figure it out (or so I seem to recall). But I went through misery trying many, many things that didn't work. Why it isn't a simple, functional default is beyond me.... the web as a multimedia tool depends on Flash with Sound. Or am I completely confused??

Dell will support it and will also sell support from Canonical with it if desired. I recommend and resell Dell wherever possible because of good prices and great support. I have just been let down by the support with Linux at a user level. This could make it easy for me to get a name brand desktop with a supported Linux (not to mention a great linux distro) into the hands of consumers. But this needs to have some good sales numbers before they offer it widespread, say into laptops and higher end desktops. I hope this also moves into the server end. I would really like to be able to buy a pre-configured Ubuntu LAMP or Ubuntu Email server from Dell. I could see Ubuntu being able to offer such things through them where as other OS's can't. This could get interesting. If nothing else it may make Dell more aware of choosing Linux compatible hardware and vendors that are open to producing Linux drivers. It seems that most other vendors that support Linux 100% charge extra for the hardware. But if I buy cheaper hardware say from Dell, I am holding my breath that everything is compatible. This could end up being win win for me, cheap hardware plus compatibility. I've got my fingers crossed. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

It's "K12"LTSP after all! THe advantages of K12LTSP are many -- it's cheap, great for recycling old equipment for workstations (don't use less than a good Pentium 3 that is easy to configure with PXE though -- since you can get these for free easily enough why waste your time with anything older...), VERY easy to add new clients once you have it all working, it's easy to manage, and it's pretty much turn-key in terms of providing loads of software that teachers can use. Tons of great software is available. The disadvantages are also many -- you'll have lots of teachers assuming that they can run their expensive, specialty educational software on the system--I'm talking that glitzy stuff that folks like Scholastic put out for megabucks that always seems to require student plugging CDs into drives, specialised client software that only runs on Windows (instead of web based). That said, with major tweaking you can always get this crap to work if your teachers are desperate and insistent enough (e.g. using remote desktop, but this requires a windows server running remote desktop service plus licenses, and often virtual CD emulation, blah blah blah ... tech nightmares that could so easily be solved by good cross platform, network-based software; it all drives me nuts that they can't do it right). Other disadvantages include having to learn a whole new operating system and way of doing things ... I have the advantage of already knowing a fair bit about Unix-style OS's and I still had (and have) a learning curve. And, finally, the biggest issue I've struggled with is that basic 21st century internet things like SOUND and MULTIMEDIA are not easy to do with K12LTSP. Not easy at all. But it's all DOABLE, and good fun if you're up for a challenge. If I could recommend anything it would be to get a good book on linux, take your time, get a small lab (one server + 2 clients) running, and experiment. Use the K12LTSP wiki and list -- folks here are very helpful. Also, use Google to search the list before you make posts, because 99% of your issues will likely already be discussed. That said, lots of people ask "dumb" questions, and nobody ever complains, and 99% of the time the answer simply gets cheerfully repeated. When you're ready to roll in a serious way I would advise considering getting a powerful and reliable server with RAID-1, fast hard drives, dual 64-bit processors, etc. just so that the experience starts off well and runs reliably. I'm sure lots of folks use old equipment for servers, but since it's the backbone of your network, splurge a little. That said, 64-bit is not as well supported as 32-bit and will cause you a few headaches with software compatibility (Flash being the most notorious). Finally, I would recommend that you don't just post to one person with questions, as you did with me, but post to the entire list, as you will likely get more and better information and it will be kept on public record.

In-Reply-To: References: Message-ID: OK, NECC is coming up (June 24 - 27 in Atlanta), and this is a combination of a status report and a call for volunteers/help. Please forward this post to your Free and Open Source Software friends! NECC is the National Educational Computing Conference (http://center.uoregon.edu/ISTE/NECC2007), and it attracts over 15,000 educators each year. It's one of the largest (if not the largest) educational technology shows in the world. For the last several years NECC has supported an "Open Source Pavilion" (apologies to Richard Stallman) with a Linux thin-client lab for demonstration purposes. Last year we added a speaker series, which is now a part of the main NECC program. This year we are getting our own large room (!!) and adjacent hallway space. Hurrah! This years speakers can be seen at our organizing wiki: http://necc2007.wikispaces.com/Speakers. There will also be two "Birds of a Feather" sessions on FLOSS: http://necc2007.wikispaces.com/Birds+of+a+Feather. OK. Now, about getting help! We need: 1. "Swag." We've gone round about on this, and aren't sure how successful it is to give things away, but people sure like it. CDs/DVDs have been the rule, but we wouldn't turn down t-shirts or buttons or pens or anything. OK, you big-gun FLOSS companies--this is easy stuff! 2. Logistical funding. We are bringing 60+ computers to Atlanta, a couple of servers, and lots of networking gear. Got some extra cash? We'd also love to get some brightly-colored t-shirts for our volunteers. 3. Setup volunteers. We'll set up the lab and computers late Saturday afternoon/evening. Maybe we'll get some pizzas and make it a party. 4. Volunteer for "milling around." The Open Source Pavilion needs folks who'll just answer questions (mostly really basic) about what FLOSS is. Come for an hour, or come for three days. 5. "Playground booths." These are 5 - 10 stations where we'll be demonstrating different FLOSS programs. Previously we've showcased OpenOffice, GIMP, Audacity, Linspire, SchoolTool, Edubuntu, Moodle, Firefox, and Knoppix. We're open to just about anything that you'd like to demonstrate that will give our attendees some good hands-on, one-on-one demonstrations. We welcome proposals from commercial vendors who will commit themselves to also supporting the FLOSS ideals and helping out in general. 6. Podcasting. Want to record our speakers for posting audio recordings of their presentations? (Paul Nelson?) Let us know. 7. Computers. It would help a ton to have computers/laptops we don't have to ship from California for the thin-client lab. Also, each playground booth will need two or three computers for demonstrations. 8. Students. Got some students who are using FLOSS? We'd love them to help in the Pavilion and demonstrate at the playground booths. They get a free t-shirt and lunch each day. We've even got some open, unscheduled lab time and we could have them do short presentations! You can go to the wiki (http://necc2007.wikispaces.com) to sign up to volunteer or send me an email letting me know what you can do. Also: For reference, my interview series on FLOSS in education is at http://edtechlive.wikispaces.com. And are you an educational blogger? Check out our all-day Saturday EduBloggerCon (http://edubloggercon.wikispaces.com) 2007 meet-up.

Message-ID: Is there any way to add tag based browsing (like Gmail) to linux? e.g. At our school we do thematic curriculum and often we would want to place one document under different headings. For example on the theme of water we could have a poem about water and a science experiment. We could file them /water/science and /water/english or we could file them as /science/water and english/water By filing with tags and using a tag browser we could browse for the folder using either logic. I have googled, but haven't come up with anything solid yet. Beagle and saved searches is not what I am after. I would like a virtual filing system that can be browsed based on tags. Subdirectories would show other tags connected with files that have the first tag. An example would be simpler. My (simple) system has three files and several tags. Water poem.odf - tag:water, english, poem, ice Water experiment 1.odf tag: water, science, chemistry,experiment, freezing, ice Water experiment 2.odf tag:water, science, chemistry, experiment, dissolving If we open the water directory we get all the documents, with all the other tags listed as sub-directories. If we go to the science sub-directory we will see both experiments listed. with chemistry, experiment, freezing,ice and dissolving shown as subdirectories. If we go back to the water directory and open the ice directory we will see Water poem and Experiment 1. Or something along these lines. This will be useful for indivual users filing and also for the shared file storage area where all teachers put there lesson plans and resources. Does anyone know of any system that can do this on our K12LTSP 6 system? Thanks. Krsnendu dasa -------------- next part -------------- An HTML attachment was scrubbed...

Probably not. It looks like tuxtype wants 800x600 which is not going to be good for most LCD monitors. It may be possible to turn off the warning notice at each monitor but we won't know until you try. What setting the screen resolution will do is force a particular terminal to use that resolutions. But that can be overridden by an application requesting a different resolutions. From what I have seen in the classroom, having the app running in a window is OK for the kids. If the issue is the mouse gets bumped and the window loses focus (and suddenly the student input fails to happen) that can be solved with window manager settings (change from focus follows mouse to click to focus should do it). > > On 03/05/07, James P.

The BIOS does not have a section for specifying the memory allocated to the onboard i810 video. So, I am ending up guessing, which is never a good thing when diagnosing issues like this. Using videoram values of '32768' and '65536' cause the X server to not even start. Using 16384 it starts OK, however I still receive the same 'insufficient resources' when viewing lots of images. The CacheLines directive doesn't seem to make a difference, no matter its value.

You can determine how much RAM the video is grabbing by knowing how much RAM the box has and looking at the output of "free" on the box once things are running. The difference between the box total and the "TOTAL" amount has been allocated to video RAM. Then put that amount in lts.conf as X_VIDEORAM = abcM (take the amount you determined and divide it by 1024 -OR- use "free -m" to get the amount in MB).

They really aren't related. The 'videoram' setting is normally not needed. the Xserver is supposed to be able to figure it out automatically, by probing the card BUT, sometimes, with some chipsets, it fails. In those cases, we need to tell it how much ram to use. In most of those cases, telling it 4mb or 8mb is about all you need to do. Sometimes, you can see how much ram is used for video by looking in the bios configuration tool. A typical setting would be: X_VIDEORAM = 8192 X_VIDEORAM = 4096 X_VIDEORAM = 3072 Try one of those settings to see if it helps. Jim McQuillan jam at Ltsp.org > Any other suggestions?

I tried all three. 8192 and 4068 gave similar results - complete crash & lock when loading a big firefox page. 3072 won't even start the client, though at least there I can press 'enter' to have it try again (unsuccessfully). As an aside, the reason I was using system RAM is because I thought, in the case of integrated devices, they were shared. -Michael On Thu, 03 May 2007 10:08:48 -0400, Jim McQuillan wrote: > I'm wondering why you are using the size of your system ram, to > determine how much memory your video card has.

So 256x1024=262144. 262144-254980 = 7164 which is just under 8MB RAM set aside for video. So if you use 8 or higher, it won't work.

At this point I would suggest checking the age of the X server running on the clients. Is it a version with i810 bugs? (I avoid that chipset like the plague...). You may need to roll your own X driver to get a better supported driver for those machines. Try loading up a lot of other apps besides Firefox and see if the X server crashes. I have issues with Firefox all the time (memory leaks, crashes, freezes, etc) and they seem to sometime trash the window manager and force a reboot to clean up.

If you type CTRL+ALT+F1 and log in as an LDAP user there, how fast is it? If that's faster, I suggest that your desktop (Gnome?) is accessing the filesystem heavily and you have slow NFS.

If you wanted to cherry-pick the latest Firefox (v2 from the upcoming Fedora 7), you could: yum --enablerepo=development update firefox While I did this (on FC6) and it worked great for me, caveat emptor and all that.

Your profiles will get larger and larger over time especially if people are saving everything to "my documents" and it will slow the login down. We are using roaming profiles. In a thin client environment, is there an alternative? I'd be interested in finding out how others are getting around the slowness problem. Is the solution simply more bandwidth and/or more server speed? Our smbldap server is on a 100Mbps port. When we first started a few months ago, all was fine and relatively quick.

I can barely sleep at night. We are starting a online student portfolio project next year that will add lots of data that needs to be safely stored, backed up, etc...

How will I know if something goes wrong? and what is the best way to backup all of this data? We are a single site independent charter school with a maximum enrollment of 320 students K-12.

We had to create the material ourselves, though, and it was completely web based. I also ran a language lab for a university and we used English Discovery (IIRC), which I got off the flaky Windows 2000 server and onto Red Hat, including the dongle and license software (that feat garnered me a job offer from the software company, by the way). The client stuff was simple enough that it would work in Wine now, so I suspect you COULD get everything working if you really needed to, but it'll be a PITA no matter what. If you're looking for significantly more than listening and pronunciation practice, the software is heavily geared towards Windows, so you'll probably end up there. If you need video, listening, and pronunciation practice, you can achieve that fairly easily with thin clients. Take a look at Praat (http://www.fon.hum.uva.nl/praat/)for phonetic and pronunciation work.

Hardware RAID is far superior to software RAID. What we do is - the students data lives on a file server with a RAID 5 array. - every night this data is copied to another RAID 5 array at the opposite end of the school, in a completely separate building. We use rsync. - every night this backup is further backed up to tape. - the tapes are stored in a third part of the school. The only weakness in our solution is someone is assuming that the wooden bookshelf the tapes live in is fireproof, but I don't worry to much. In theory our recovery strategy is - if the file server dies, the backup server can become the file server. - if the backup server dies, no problems, just get another file server and continue the scheme - if an aeroplane crashes and wipes out the whole site, tough, although I do have the a tape under the bed at home so we could get back some of the students data (albeit a month or two out of date). -- Regards Martin Woolley ICT Support Handsworth Grammar School Isis Astarte Diana Hecate Demeter Kali Inanna ************************************************************* This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

But if you are adding much more data in the future you may start to see performance hits with a single IDE where you don't right now. My suggestion would be to add in a PCI RAID card to handle some redundancy and fail over. I would think that if you were happy with a single IDE in the past a SATA card would still meat your budget needs and be fast enough. If you have the money I would recommend SCSI, but that would add some extra stress on the budget. If you just want redundancy get a card that can mirror (RAID 1), if you want to be safe on the speed side get a card that can handle striped mirrors (RAID 0+1 or RAID 10, mirrored stripes or striped mirrors respectively). I am not sure how many SATA RAID cards handle RAID 0+1 or RAID 10 so that may put you into the SCSI realm. You could go with a RAID 5 but my experience is that the redundancy is great, but the speed isn't quite there. I recommend hardware RAID whenever possible, I am not much of a fan of software RAID. If your PDC is what currently contains your /home directory, then I would put the drives in the PDC. I recommend putting your OS on a separate drive and running your /home alone on the RAID. You could easily move your data by adding the RAID Array and mounting it temporarily as /newhome then rsync /home to /newhome, then remount the array as /home. Very easy way to add the new drives but not have to mess with your server at all. Also then you can enable disk quotas on the /home drive. But first, BACKUP YOUR DATA! You should not sleep at night until you get a backup! I hate to shout, but I see users lose their data every day. Get a backup. If you have to move over a network share, plug in a temporary USB drive, clone with some sort of magic device, whatever, get a backup. After you have the backup, get a good nights sleep and then mess with adding new drives. As far as a permanent solution, either add in a large IDE drive, or get yourself a large external USB drive and schedule some rsync's or whatever you desire. I usually recommend maintaining a few backup sets. If you have the money get a drive large enough to hold nightly incremental backups and a weekly full backup. If you can, store a separate nightly backup for each night of the week. Backups aren't always for hardware failure. Mine get the most use via user mistakes. On our main school server I store a full month of backups by day. Then when a student or teacher realizes 7 days from now that they accidentally deleted some project that took them 1 month to create, I can go back 7 days and get it for them. If you only have one backup set, you lose that ability. The more backup sets, the farther back you can go. Hope that helps.

All my users have files stored on a Windows Server. It is known as there G: drive in windows. I'd like to create a Launcher on the desktop for them to access those file and I also need to make sure they can easily save there from OpenOffice. The launcher isn't hard to make, except that the folders are the username$ , so that they are invisible to most users. First what is the syntax for getting the current username, U$ or something like that right? Second, when I type in username$, or in my case lnkemp$, I get a cannot find folder \br2\lnkemp%24 on \br2\lnkemp%24 error. Yes I'm using smb:\\br2 \lnkemp$ , so that part is correct. What am I missing here to make this work? Or should I permenantly map the drive and just create a launcher for that?

If /etc/k12ltsp-release says version 5, than you're running version 5. Maybe I don't understand what you're asking here. Yum update will perform updates within a certain release. It will not upgrade you between releases, though it can be made to do so by installing the k12ltsp-release from a newer release. This can have mixed results. Getting the new ISOs and upgrading through the installer is the preferred upgrade method. -- Dan Young Multnomah ESD - Technology Services 503-257-1562 From jbaillie at stmarys-school.org Fri May 4 17:33:32 2007 From: jbaillie at stmarys-school.org (John Baillie) Date: Fri, 04 May 2007 13:33:32 -0400 Subject: [K12OSN] yum update and etc/k12ltsp-release Message-ID: <463B6E6C.4060507@stmarys-school.org> Dan Young wrote: Maybe I don't understand what you're asking here.

If you use the Upgrade function in K12LTSP, it will not require a total "blank the hard drive and reinstall". BUT - do a backup of all critical files first! While the upgrade process is an rpm guided action, there are still a few config files that don't get handled properly during an upgrade. In 99.5% of cases, either the new version will create a config.rpmnew or move the original to config.rpmsave . It's been a long time since I've seen it but some earlier upgrades would simply overwrite the original config file. Where things get a bit messy is when the layout of the config file changes. You will need to do a manual reconfig in that situation. -- James P.

It's very efficient in its use of space--any file that is unchanged from yesterday's backup gets hard linked in today's backup. It doesn't do pooling, though. If you rename a large directory tree--rsnapshot thinks that the old directory is gone, and a new directory showed up, so that directory tree gets backed up twice in that case. -Rob On Fri, May 04, 2007 at 02:25:21PM -0700, Huck wrote: > Les is who I'd defer to in this question, but IMO you will most likely > want SOME fulls....I keep 4...why?

Be sure to stock up on antacid. Strong drinks are also advised. First off: the ONLY sure solution is to wipe the drives and reinstall from scratch. Don't even think of doing anything else. Just before you wipe the drives, backup all your critical config files and go over them manually to verify they are good (always keeps a backup copy of critical config offline somewhere). Once you reinstall, turn off root login with ssh without keys. This will block 99% of all of the brute force attacks as the keys can't be guessed. This happens to everyone eventually so don't be too hard on yourself. You can run some rootkit detectors (rkhunter is actively updated) but it won't solve the problem. However, it can alert you to the intrusion. Other things to do are to the install the ssh brute force detection tools (there are many - sshdeny, sshblock - names are fuzzy, tired - sorry). These tools will use iptables to block access from remote sites that are trying to break in using brute force methods. Keep us posted. I'll help out as best I can. Ugh. No fun for Jim tonight...

Before the 3.x versions, backups were always based on the last full, so the incrementals would transfer an increasingly large set of files. Now it is possible to base them on the last incremental instead, but it is still a good idea to do the fulls. The difference is that an incremental skips files where the name, length, and timestamp match your existing backup. On fulls, both copies are read and compared with the rsync block checkup algorithm. This takes some CPU time at both ends but not much bandwidth and verifies that your current copy is still good. Also during full runs the backup directory is completely rebuilt for faster access on the next run. -- Les Mikesell lesmikesell at gmail.com From nadavkav at gmail.com Sat May 5 06:53:40 2007 From: nadavkav at gmail.com (Nadav Kavalerchik) Date: Sat, 5 May 2007 09:53:40 +0300 Subject: [K12OSN] Help: System intrusion through ssh and a weak password In-Reply-To: <1178316590.7465.43.camel@merlin.localnetsolutions.com> References: <8b88203f0705041414x6c765f76sc271a646e65091e2@mail.gmail.com> <8b88203f0705041415x316e486aoc9652028928d93ed@mail.gmail.com> <1178316590.7465.43.camel@merlin.localnetsolutions.com> Message-ID: <4219988b0705042353o19ecb9abm4b7b6a5c7a9701da@mail.gmail.com> we're using freenx through ssh to remote control all the school that are installed with ltsp what we did is moved the ssh port somewhere high in the port list, it solved all the "scanning" and trying to "break in" log entries that we used to see in the log file :-) (i wonder how long it will last) On 5/5/07, James P.

Make sure you don't have the DHCP server running on the virtual machine; no need and it would interfere. This assumes that you have sufficient RAM and that you export your /home to include the virtual server. You could even include a second virtual NIC to communicate with the host over the hostonly network (reducing load on the physical NIC). There will be a loss of performance (since your are doing more and have divided your resources), but for testing you should be able to live with it. I did a similar thing, but with a K12LTSP 5 (ltsp 4.2) VM running on a K12LTSP 4 host. I also used VMware server to create a virtual diskless workstation, complete with USB storage and soundcard. I ran both "real" terminals and virtual terminals on both real and virtual servers. On my laptop I have a complete demonstration network: virutal K12LTSP 5 server on the "hostonly" network with a virtual diskless workstation, communicating through a virtual IPCop firewall to the "NAT" network (so that it works wired, wireless, or disconnected). All with only 1GB of RAM and using VMware Player (virtual machines were created with VMware Server and copied to the laptop). The host OS on the laptop is Fedora Core 6. > I am currently running two ltsp servers in parallel and for one of the > thin clients I have specified that I want it to run form the first > server only by specifying server = ltsp1 in lts.conf.

The students at Liverpool High have used their school-issued laptops to exchange answers on tests, download pornography and hack into local businesses. When the school tightened its network security, a 10th grader not only found a way around it but also posted step-by-step instructions on the Web for others to follow (which they did). Scores of the leased laptops break down each month, and every other morning, when the entire school has study hall, the network inevitably freezes because of the sheer number of students roaming the Internet instead of getting help from teachers. So the Liverpool Central School District, just outside Syracuse, has decided to phase out laptops starting this fall, joining a handful of other schools around the country that adopted one-to-one computing programs and are now abandoning them as educationally empty ? and worse. Many of these districts had sought to prepare their students for a technology-driven world and close the so-called digital divide between students who had computers at home and those who did not. "After seven years, there was literally no evidence it had any impact on student achievement ? none," said Mark Lawson, the school board president here in Liverpool, one of the first districts in New York State to experiment with putting technology directly into students' hands. "The teachers were telling us when there's a one-to-one relationship between the student and the laptop, the box gets in the way. It's a distraction to the educational process." Liverpool's turnabout comes as more and more school districts nationwide continue to bring laptops into the classroom. Federal education officials do not keep track of how many schools have such programs, but two educational consultants, Hayes Connection and the Greaves Group, conducted a study of the nation's 2,500 largest school districts last year and found that a quarter of the 1,000 respondents already had one-to-one computing, and fully half expected to by 2011. Yet school officials here and in several other places said laptops had been abused by students, did not fit into lesson plans, and showed little, if any, measurable effect on grades and test scores at a time of increased pressure to meet state standards. Districts have dropped laptop programs after resistance from teachers, logistical and technical problems, and escalating maintenance costs. Such disappointments are the latest example of how technology is often embraced by philanthropists and political leaders as a quick fix, only to leave teachers flummoxed about how best to integrate the new gadgets into curriculums. Last month, the United States Department of Education released a study showing no difference in academic achievement between students who used educational software programs for math and reading and those who did not. Those giving up on laptops include large and small school districts, urban and rural communities, affluent schools and those serving mostly low-income, minority students, who as a group have tended to underperform academically. Matoaca High School just outside Richmond, Va., began eliminating its five-year-old laptop program last fall after concluding that students had failed to show any academic gains compared with those in schools without laptops. Continuing the program would have cost an additional $1.5 million for the first year alone, and a survey of district teachers and parents found that one-fifth of Matoaca students rarely or never used their laptops for learning. "You have to put your money where you think it's going to give you the best achievement results," said Tim Bullis, a district spokesman. Everett A. Rea Elementary School in Costa Mesa, Calif., where more than 95 percent of students are Hispanic and come from low-income families, gave away 30 new laptops to another school in 2005 after a class that was trying them out switched to new teachers who simply did not do as much with the technology. Northfield Mount Hermon School, a private boarding school in western Massachusetts, eliminated its five-year-old laptop program in 2002 after it found that more effort was being expended on repairing the laptops than on training teachers to teach with them. Two years ago, school officials in Broward County, Fla., the sixth-largest district in the country, shelved a $275 million proposal to issue laptops to each of their more than 260,000 students after re-evaluating the costs of a pilot project. The district, which paid $7.2 million to lease 6,000 laptops for the pilot at four schools, was spending more than $100,000 a year for repairs to screens and keyboards that are not covered by warranties. "It's cost prohibitive, so we have actually moved away from it," said Vijay Sonty, chief information officer for the district, whose enrollment is 37 percent black, 31 percent white and 25 percent Hispanic. Here in Liverpool, parents have long criticized the cost of the laptop program: about $300,000 a year from the state, plus individual student leases of $25 a month, or $900 from 10th to 12th grades, for the take-home privilege. "I feel like I was ripped off," said Richard Ferrante, explaining that his son, Peter, used his laptop to become a master at the Super Mario Brothers video game. "And every time I write my check for school taxes, I get mad all over again." Students like Eddie McCarthy, 18, a Liverpool senior, said his laptop made him "a lot better at typing," as he used it to take notes in class, but not a better student. "I think it's better to wait and buy one for college," he said. More than a decade ago, schools began investing heavily in laptops at the urging of school boards and parent groups who saw them as the key to the 21st century classroom. Following Maine's lead in 2002, states including Michigan, Pennsylvania and South Dakota helped buy laptops for thousands of students through statewide initiatives like "Classrooms for the Future" and "Freedom to Learn." In New York City, about 6,000 students in 22 middle schools received laptops in 2005 as part of a $45-million, three-year program financed with city, state and federal money. Many school administrators and teachers say laptops in the classroom have motivated even reluctant students to learn, resulting in higher attendance and lower detention and dropout rates. But it is less clear whether one-to-one computing has improved academic performance ? as measured through standardized test scores and grades ? because the programs are still new, and most schools have lacked the money and resources to evaluate them rigorously. In one of the largest ongoing studies, the Texas Center for Educational Research, a nonprofit group, has so far found no overall difference on state test scores between 21 middle schools where students received laptops in 2004, and 21 schools where they did not, though some data suggest that high-achieving students with laptops may perform better in math than their counterparts without. When six of the schools in the study that do not have laptops were given the option of getting them this year, they opted against. Mark Warschauer, an education professor at the University of California at Irvine and author of "Laptops and Literacy: Learning in the Wireless Classroom" (Teachers College Press, 2006), also found no evidence that laptops increased state test scores in a study of 10 schools in California and Maine from 2003 to 2005. Two of the schools, including Rea Elementary, have since eliminated the laptops. But Mr. Warschauer, who supports laptop programs, said schools like Liverpool might be giving up too soon because it takes time to train teachers to use the new technology and integrate it into their classes. For instance, he pointed to students at a middle school in Yarmouth, Me., who used their laptops to create a Spanish book for poor children in Guatemala and debate Supreme Court cases found online. "Where laptops and Internet use make a difference are in innovation, creativity, autonomy and independent research," he said. "If the goal is to get kids up to basic standard levels, then maybe laptops are not the tool. But if the goal is to create the George Lucas and Steve Jobs of the future, then laptops are extremely useful." In Liverpool, a predominantly white school district of nearly 8,000 students, one in four of whom qualify for free or reduced lunches, administrators initially proposed that every 10th through 12th-grade student be required to lease a laptop, but decided to make the program voluntary after parents protested. About half the students immediately signed up; now, three-quarters have them. At first, the school set up two tracks of classes ? laptop and non-laptop ? that resulted in scheduling conflicts and complaints that those without laptops had been shut out of advanced classes, though school officials denied that. In 2005, the school went back to one set of classes, and bought a pool of 280 laptops for students who were not participating in the lease program. Soon, a room that used to be for the yearbook club became an on-site repair shop for the 80 to 100 machines that broke each month, with a "Laptop Help Desk" sign taped to the door. The school also repeatedly upgraded its online security to block access to sites for pornography, games and instant messaging ? which some students said they had used to cheat on tests. Maureen A. Patterson, the assistant superintendent for instruction, said that since the laptop program was canceled, she has spoken to more than 30 parents who support the decision and received five phone calls from parents saying they were concerned that their children would not have technological advantages. She said the high school would enlarge its pool of shared laptops for in-class use, invest in other kinds of technology and also planned to extend building hours in the evening to provide computer access. In a 10th grade English class the other day, every student except one was tapping away on a laptop to look up food facts about Wendy's, McDonald's, and Burger King for a journal entry on where to eat. The one student without a computer, Taylor Baxter, 16, stared at a classmate's screen because she had forgotten to bring her own laptop that day. But in many other classrooms, there was nary a laptop in sight as teachers read from textbooks and scribbled on chalkboards. Some teachers said they had felt compelled to teach with laptops in the beginning, but stopped because they found they were spending so much time coping with technical glitches that they were unable to finish their lessons. Alice McCormick, who heads the math department, said most math teachers preferred graphing calculators, which students can use on the Regents exams, to laptops, which often do not have mathematical symbols or allow students to show their work for credit. "Let's face it, math is for the most part still a paper-and-pencil activity when you're learning it," she said. In the school library, an 11th-grade history class was working on research papers. Many carried laptops in their hands or in backpacks even as their teacher, Tom McCarthy, encouraged them not to overlook books, newspapers and academic journals. "The art of thinking is being lost," he said. "Because people can type in a word and find a source and think that's the be all end all."

OTOH, most of those issues go away with LTSP. It's cheap: a single desktop computer can power a whole 1:1 classroom of thin clients/used PCs; and it allows the teacher to keep control. With laptops, you (the teacher/administration) lose control over what the kids do with them when they walk out the door. With LTSP, the kids have the computers where they need them, in the classroom, but not all the other times. Whether computers help education or not is arguable. But buying kids laptops is clearly one of the worst ways to find out.

For laptop projects like this to be successful, ALL of the schools curriculum would have needed to be revamped to make regular, daily use of it. Replacing all textbooks with e-textbooks, replacing all manual note taking with computer notes, in general replacing paper with bits would be an excellent use of these tools, and might even have paid for a large portion of the program. I would even go so far as to speculate that a school focused on using a research based curriculum would perhaps be the best use of laptops in schools. Throwing laptops into the school and expecting results from that alone, without the training on how to make use of the tool, well, that was just asking for trouble. _____ Steven Santos Director, Simply Circus, Inc.

I figured kids would be doing all that. And yes, maintenance on laptops is indeed quite costly. Yes, LTSP pretty much solves all of those problems. --TP Krsnendu dasa wrote: > NY Times May 4, 2007 > Seeing No Progress, Some Schools Drop Laptops > By WINNIE HU > LIVERPOOL, N.Y. ?

If those objectives could be met, there is still no guarantee that the effort involved in accomplishing such miracles was the best use of resources. The potential payoff is there, but such such solutions are often oversold. As one who has been involved in technology for 25 years, I am still ambivalent about it's value in many situations. Personally I have always found that an inspiring teacher will always inspire, with or without technology. Striking the appropriate budgetary balance of technology with recruitment and retention of good teachers and all other (non-tech) resources is the trick. -- "History doesn't repeat itself; at best it rhymes." - Mark Twain | John Lucas MrJohnLucas at gmail.com | | St. Thomas, VI 00802 http://mrjohnlucas.googlepages.com/ | | 18.3?N, 65?W AST (UTC-4) | From rowens at ptd.net Mon May 7 00:37:48 2007 From: rowens at ptd.net (Rob Owens) Date: Sun, 6 May 2007 20:37:48 -0400 Subject: [K12OSN] Fwd: of interest regarding ICT use in schools In-Reply-To: References: <463D5918.8020900@dasya.com> Message-ID: <20070507003748.GB17120@clubber.owens.net> Two comments: 1) Much of the complaints in this article had to do with cost, maintenance, and "technical glitches" (my gues is that means virus problems). LTSP cures a lot of this. 2) They are judging student performance based on standardized test scores, which I've always thought was a poor indicator of anything except a student's ability to do well on standardized tests. -Rob On Sun, May 06, 2007 at 10:23:11PM +1200, Krsnendu dasa wrote: > NY Times May 4, 2007 > Seeing No Progress, Some Schools Drop Laptops > By WINNIE HU > LIVERPOOL, N.Y. ?

Obviously, yes, but the reality is that standardized tests are the means by which schools are judged and rated. The move is toward, not away from standardized tests. I am a big proponent of technology, but there are many situations where it makes little difference in the classroom. The ability for students to get better assistance out of school or in study hall is a great thing. I'm still up in the air about its usefulness in the normal classroom. People spend a lot of time on glitz and show for presentations and the like when giving the students a good, solid, interesting lesson would be better.

While we had computers when I was in school, we never actually depended on the computer to do education, unless it was a computer programming class. We actually wrote papers longhand, we actually learned how to *properly* type error-free (yes, with typewriters), and we did math problems *on paper*. If a math problem took five pages to "show your work," then so be it. To this day, I can do an integration by parts with trig substitution, not because I'm brilliant, but rather because I didn't have the computer shortcut and actually had to learn what I was doing and why. Thank you, Mr. Madden, Mr. Ahrens, and all you others. Schools should go back to that. It works...REALLY well. Too many of them these days come to a complete, screeching halt if "the computer" goes down. Use the technology, as appropriate...but don't bet every aspect of education on that one specific tool called "the computer." --TP From krsnendu108 at gmail.com Mon May 7 05:04:01 2007 From: krsnendu108 at gmail.com (Krsnendu dasa) Date: Mon, 7 May 2007 17:04:01 +1200 Subject: [K12OSN] smbldap user creation home directory problems Message-ID: I have been using smbldap-useradd bulk for add all my users without any problem till now. I used the same syntax I alway used. When he tried to log in he got the message that there is no home directory. So I ran the command again making sure to use the -m option. After running this command it gave a warning message like "the id number of the /home/user directory does not match the user id of this user." Now when he tries to log in he gets the "User's $HOME/.dmrc file is being ignored. This prevents the default session and language from being saved. File should be owned by user and have 644 permissions. Users $HOME directory must be owned by the user and not writable by other users." I tried changing the user number of the user, but I still can't log in properly. I get errors saying something like gconf cannot write. I tried changing the ownership of /home/user too but that also didn't seem to help. I have been running two ltsp servers in parallel. Perhaps this is causing the problem. I have shut down the other server now, but the problem remains. Any clues what I should do now?

In both situations, I have installed Sabayon to try to create managed profiles for the Gnome desktop. I would also like to try to manage some of the students' web browsing through a whitelist or blacklist (I think). The distros have Squid, SquidGuard, and Dans Guardian included. However, I must admit, I am too much of a Linux noob to understand how to get the results I want with these tools. Question # 1 -- After creating a profile with Sabayon, do I somehow need to copy this profile to all user's home or other folders? The profile doesn't always seem to be applied uniformly to the users that I assign the profile to. I think the Sabayon web site says something to this effect. Question # 2 -- I have tried to get Squid and SquidGuard set up and running in each distro, but when I check processes and services, neither is listed as running and trying to start / restart them either hangs or produces an error message. Do I need to configure and start Squid, then SqidGuard, or Dans Guardian? Would anyone be willing to share a step by step description of how one configures these tools? The directions I have tried to follow from the respective web sites are not working for me (sorry for my ignorance). I think I would like to limit internet browsing from the LTSP clients with Firefox to a "whitelist" of sites. Are these the tools to do that with, and how? Thanks for any expertise you are willing to share.

I no nothing of System76 but I can tell you that they are, after all, a company that is out for a profit just as much as Dell, HP or IBM. I would look at purchasing a laptop of your choice and putting your preferred distro on it. For example, if you want to buy a Dell laptop with Winders on it then ask for the $50 rebate and install your favorite flavor of Linux. You paying an extra penny to System76 isn't supporting the community, it's you paying more. Just my two cents. /paul ________________________________ Paul VanGundy Linux Systems Administrator paul.vangundy at webex.com ________________________________ ________________________________ From: k12osn-bounces at redhat.com [mailto:k12osn-bounces at redhat.com] On Behalf Of Jason Neiffer Sent: Monday, May 07, 2007 3:42 PM To: Support list for open source software in schools.

The only thing that doesn't work is the built-in Winmodem, which, fortunately, I don't use anyway. Of course, there is the issue of Broadcom wireless with the D600 and D610, but I got that working just fine with a 2.6.17-and-later kernel and some firmware. CAVEAT!! If you want to max out the DRAM with a Dell laptop, be careful to buy only 3GB of DRAM, not 4GB. We found out the hard way, with the D820, that you lose 768MB if you try installing the full 4GB, leaving only 3.25GB.

Mainly it's the use of use-host-decl-names vs get-lease-hostnames. I've read the man pages, but I still don't fully understand under what circumstances I should use either setting. What I would like to have is all name resolution taking place on my Windows DNS server, and keep my /etc/hosts file free of any names except for the localhost line. I think I'll have to manually update my DNS records, because Linux DHCP can't automatically update Windows DNS, and that's ok with me. For DHCP, I've got a dynamic range and a static range. The static range is primarily for LTSP terminals that have printers attached. This is a single-nic setup. Any advice would be appreciated. The other difference is in the 2 sample dhcpd.conf files is the use of bootp options in the K12LTSP file, where the LTSP sample file doesn't mention bootp at all. Do I need it? What's it used for?

Whether or not it needs to be the FQDN seems to be up for debate. If your DNS works, it probably doesn't matter. Somebody more knowledgeable may disagree.

You've also got to ask yourself how much it's going to cost you in time to make some nVidious or Broadcom crap actually work with GNU/Linux.

They (NVidia) may not have an open source driver, but the driver they have is top notch. The disaster with laptop video happens with the use of shared RAM. All of the Intel video I have ever seen in a laptop use shared RAM. It is possible to get dedicated graphics RAM with NVidia chips in laptops. Making a laptop work with Linux is no easy matter. The overall quantity of no-driver hardware on the systems is frustrating. The only advantage of Dell joining the fray on supplying laptops with Linux is it _may_ help push some stubborn manufacturers into writing drivers for Linux or opening up their specs so someone else can. > --TP > _______________________________ > Do you GNU!? > Microsoft Free since 2003--the ultimate antivirus protection! > > > > Timothy Hart wrote: > > The prices on system76 don't seem that crazy.

I went all Intel specifically because the drivers were in the kernel and I wouldn't have to mess around with anything. I gave the tech a list of specific, well-supported chips. I picked it up last night, went to install Ubuntu 7.04, and found he'd slipped a crap Marvel wireless card in instead of the Intel Pro I had ordered. Sometimes, even when you research and plan, you still can't get things to work.

Much of the problem is in the text books, not just the technology. I have had to teach all of my children how to really do really factor numbers. I used the Sieve of Eratosthenes to help my youngest son to really understand factoring. With my oldest son, when I complained to the principal (whose son was in the same class), her reply was, "I wondered what my son was doing sitting at the dining room table guessing numbers".

ATI, now that is another story. A long other story. Plus I would like some graphics horsepower in the laptop as I run some 3d apps that could use it. Second Life for education anyone? I agree James that Dell coming on board is a good thing over all. If it fails it won't hurt Linux in general. Linux is bigger than that. However it will legitimize Linux in the eyes of some people. That is good for us all. Tim On 5/8/07, "Terrell Prud? Jr." wrote: > > That's probably because that Marvell piece of junk is cheaper and he > thought he could pull a fast one.

Talk to the System76 guys. They should be able to make it right. Two of the guys from there were here in Sevilla, Spain for the Ubuntu developer summit this week. They're good guys, and I'm guessing it was just an honest mistake made by someone. Didn't that system come with Feisty pre-loaded?

The server I've got going right now is a little over the top in comparison with Rob's: Dual Core 2212HE Processor; 2X1MB Cache, 2.0GHz Opteron, 1Ghz HyperTransport Dual Core Opteron 2nd Processor, 2x1MB Cache, 2.0GHz1Ghz HyperTransport 8GB Memory, 4x2GB, 667MHz Dual Ranked DIMMs RAID-1 2 x 160GB, SATA, 3.5-inch 7.2K RPM Hard Drive SAS 5IR SAS, PCI-Express Internal RAID Adapter ...and it cost about $3800 CDN. BUT, right now it's powering 45 workstations and I'm hoping to get 40 more going (which might require even more RAM if they are all going to be firing at once). Maybe a little overoptimistic. But... even at 45 I feel I have my money's worth. "One server to rule them all...." it sure makes administration easy. Linking them all I have a 1 Gig 8-port network card that is utilizing existing Cat-5e cable to the four labs it's running. At each lab I have either a 5- or 8-port Gig switch (<$100 CDN) or a larger switch (24 port) with 2 1-Gig ports so that the labs are serviced by 1 Gig, but each workstation only gets 100 Mbps max. So far so good. One teacher here is totally stoked, literally giddy with excitement. He's the one that pushed me to get the Flash With Sound going. And now he wants to add all of his spelling words to Childsplay! (any takers on explaining how to do that one by the way?)

While you are working through the bugs you'll probably want to test by logging in via ssh or something similar then you'll see some meaningful debug. Here's some pointers (btw I am using Ubuntu 6.06 so it may be different if you are using k12ltsp) First make sure that you can ping the server who has the share you are trying to mount by DNS name. If not add it to /etc/hosts Remember you'll need to edit /etc/security/pam_mount.conf and then add an entry in appropriate services in /etc/pam.d/ So my pam_mount.conf file looks like: volume * smbfs SERVER ALLSTUDENTS /home/STUDENTS/&/.windowsShare uid=&,gid=&,dmask=750,workgroup=DOMAIN - - Replace SERVERNAME with the DNS name of the server that you are trying to mount. Replace ALLSTUDENTS with the share you are trying to mount from SERVER . Replace DOMAIN with your AD domain-name Then I made the following changes in /etc/pam.d/ I edited my /etc/pam.d/common-auth file to look like this: auth required pam_mount.so auth sufficient pam_winbind.so use_first_pass auth sufficient pam_unix.so nullok_secure use_first_pass auth required pam_deny.so I have a file called /etc/pam.d/common-pammount it looks like this: auth required pam_mount.so use_first_pass session optional pam_mount.so use_first_pass I edited /etc/pam.d/common-session to look like this: session required pam_unix.so session required pam_mkhomedir.so umask=0022 skel=/etc/skel session optional pam_mount.so Since I use GDM I edited my /etc/pam.d/gdm file to look like this: #%PAM-1.0 auth requisite pam_nologin.so auth required pam_mount.so auth sufficient pam_winbind.so use_first_pass auth sufficient pam_unix.so nullok_secure use_first_pass auth required pam_env.so @include common-auth account sufficient pam_mount.so @include common-account session required pam_limits.so session optional pam_console.so @include common-session @include common-password session optional pam_mount.so After I could successfully login I wrote a login script and put it in the file /etc/gdm/PostLogin/Default that automatically created a shortcut on each users desktop when they logged in that pointed to their hidden windows share (which was specified above in the pam_mount.conf file). Here's the script: #!/bin/sh # This # script will be run before any setup is run on behalf of the user and is # useful if you for example need to do some setup to create a home directory # for the user or something like that. $HOME, $LOGIN and such will all be # set appropriately and this script is run as root. #flatten all users logins so that even if they mix cases when logging in #their directory is created all lowercase. This prevents several redundent #home directory's from being created u=`echo $USER | tr A-Z a-z` # Name of desktop itself, and then Windows Share within dt=/home/STUDENTS/$u/Desktop zd=$dt/ZDrive # Create desktop if not present yet if [ ! -d $dt ] then mkdir $dt chown $USER $dt fi # Then create ZDrive within if needed if [ ! -L $zd ] then # Just in case something strange was left behind. It won't work # if they put a directory here, though. rm -f $zd # This wildcards to figure out their graduation year part of the path ln -s $HOME/.windowsShare/*/$u $zd fi Finally, just so that its all in here. This is what my smb.conf file looks like: [global] security = ads realm = YOUR.ADSDOMAIN.ORG password server = 10.114.5.50 workgroup = DOMAIN idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes template homedir = /home/%D/%U template shell = /bin/bash client use spnego = yes client ntlmv2 auth = yes encrypt passwords = yes winbind use default domain = yes restrict anonymous = 2 Obviously change YOUR.ADSDOMAIN.ORG to reflect your setup. Make the entry workgroup = DOMAIN to match your domain. I hope this helps. John Note the directive in the script to change DOMAIN to your domain name.

I've even got what seems to be mount of their Windows AD Home directory, but it's not at all what I thought it would be. When someone logs in now they get a messages stating that Users $HOME/.dmrc file is being ignored, with more info about ownership. Also the files that are in the users current home drive on AD are appearing directly in the home drive not in a mapped drive. I haven't checked to see if saving a file in that folder will save it in the AD home directory. If it does then I suppose that will work, but I can't have an error message appear at every login. Anyone else had success with using pam_mount to automount drives from a Server 2003 AD?

Below is what we'll be starting with, making the switch on labs and media centers first, next year adding teachers. -Dell PowerEdge 6800 -Quad 3Ghz/800Mhz/4mb Cache Dual Core Intel Xeon 7130 Processors -16MB 400Mhz DDR2 RAM (8x2GB to start, will handle 64GB total) -Embedded PERC4e/Di RAID Controller -6 300GB 10K RPM Ultra 320 SCSI hard drives configured in RAID 10 (3 striped 300GB mirrors for a total of 900GB storage, machine will handle 10 SCSI drives and a 2 drive media bay for future expansion, from my research this will give me the fastest possible read/write speeds while maintaining full hot swap redundancy) -2 Intel Pro 1000MT Dual port adapters for a total of four gigabit NICS teamed as one with ALB -64 Bit XUbuntu with LTSP 4.2 (I am thinking XUbuntu will give me some extra speed by not hogging as much resources as a Gnome or KDE based distro, 64-bit so that it can handle over 4GB of RAM, LTSP 4.2 since that is still the most scalable and stable version, and Ubuntu based distros seem to have a much larger software repository now that they have the full Debian repository included) I hope this will handle 90 workstations with heavy use. I plan on purchasing 90 of the DevonIT 6020P thin clients. They seem to be the fastest clients I can find in the sub $150 price range. Also in talking to DevonIT they are very familiar with LTSP and say they fully support it on their clients. Also I have seen posts on this list that say they have worked 100% out of the box. I will be purchasing 17" flat screens with USB keyboards and optical mice. Each lab will be fed by 10/100 switches with a gigabit uplink directly to the main gigibit switch that the server will be plugged into. Each lab/media center will never exceed 30 workstations. Total we will be spending around $40,000 for everything. I plan on the teacher machines being some sort of fat client derivative using full local XUbuntu clients and pulling /home and login information from the server. There will be about 60 teacher machines. I hope this server will be able to run everything from a single location. If I do need to get more horsepower I plan on adding specific application servers to offload tasks. Say if KStars drags things down too much I will add in a KStars Application server. I had looked at using SMB/LDAP along with multiple less powerful load balanced LTSP servers, but from my testing the NFS shared /home and the remote users in LDAP had a significant effect in speeds. Machine bootup and general navigation seemed delayed. This is why I am looking at keeping storage and user accounts local on a single server. We will also implement weekly 45 minute training sessions for teachers/staff. First these sessions will be about familiarizing them with XUbuntu,OpenOffice, and Firefox in general. Then we will move towards application suggestions for specific tasks and then walk them through how to accomplish the tasks. Also I plan on having a teacher machine in each lab (4 total to start). I plan on making this teacher machine in the same fashion as future teacher machines will be. Full featured fat clients with NFS mounted /home and pulling login info from the server. This will allow easy addition of a scanner or other peripherals. And it will provide a means to read CDROMS when needed or plug in a digital camera or media reader etc. Any suggestions on the fastest method for distributing login information would be great. I know LDAP which leans me towards it, but I also see NIS mentioned a lot for running local apps and such. I wonder if this would be better to use since it would allow the possibility of local apps when/if desired. Any comments or suggestions would be appreciated. This switch is making me nervous. I really don't want to spend $40,000 and have everything be slow, I want the users to think these are stand alone 3Ghz machines. But compared to the $135,000 they were going to spend on iMacs and MS Office, I think it is worth the risk. And I can't wait to be able to increase our software offerings by ten fold or more. If all goes well this will be a showcase of how well FOSS can benefit a school and will be a model for our area. If this doesn't go well...it better go well.

This is a bit off subject, but I want to ask you something. How did you convince the school to go Linux and spend only $40,000 instead of $135,000? What I am fighting with here in this county is right now they are trying to come up with a technology budget (they don't even have one currently). They are thinking that they need to replace 700 computers initially and then replace 300 per year and budget $700 per machine and that doesn't even include learning software! Instead of fighting the County, would it be better to go to the actual schools and show them what LTSP is all about? When I go to open community forums about this and mention Linux it's like everyone shudders, and the response is that we need nice multimedia workstations for our kids to learn and they will get bored with DOS. DOS is not Linux and Linux is not DOS!!

DOS is not Linux and Linux is not > DOS!! We will still have 2 OSX multimedia labs with 25 machines each. These labs will be for application specific training and for those who are scared of Linux. That will help with the transition. As far as convincing the school, it helps that I am the tech guy for 9 schools in our area. The school that this purchase will be for I am full time employed by. This will be for our High School and Junior High school which are on the same campus. The other schools will follow in years to come. Also I installed a K12LTSP in a new startup school in town about 3 years ago (maybe 4 now). They use Linux and FOSS 100% throughout the school. All student, teacher and staff machines run off of the terminal server. I go there once every summer to update the server. Having this school as a reference helps. But as far as convincing the staff, teachers, and administration, this has been about a 5 year total effort. I started by just telling them about the software and possibilities. Then I slowly moved into some demos and a small lab (I never formally told the staff that they had a new lab, I just built it and left the doors unlocked, it was their decision if they wanted to wait for the mac lab or try this new thing out) to show what things looked like. Every time budget shortfalls came up in discussion I mentioned FOSS and how it could save money. But I think the most important part is I never told anyone that we had to switch. I just kept throwing the bone out and then as they asked more and more about it I gave them needed information but told them that we wouldn't make the change because I didn't think they were ready. Finally this year the President of the school told me we had $50,000 to update teacher machines and he would like to switch from Macs to Windows. I gave him the usual lines about how Windows is subject to spyware and viruses and tough to manage... yadda, yadda, yadda. I told him that if we went to Windows we might have to hire another person part time. I said as much as I don't like Macs (flame away :-) I thought that at this point Macs were the best option as they didn't put too much change on the teachers and staff, and that if we were willing to move to Windows we may as well go Linux. Then explained how much each option would cost but said again, I don't think our staff and teachers can handle the change yet. I told him if I had my choice of what to do, I would upgrade all the lab and media center machines for less than the budgeted $50,000 this year (which would only have updated a portion of teacher machines), let students and teachers adjust to that change for a year (I would put Firefox and OpenOffice on the Teacher Macs for a little compatibility but not too much change). Then the following year convert the teachers for a fraction of the cost of going with Windows or Mac. But then said that I didn't think we should go that way because it would put too much stress on the staff/teachers to make the change and it could cause some small curriculum hiccups which would require change. Long story short the President finally said "I want to go with this Linux open source stuff, if we can offer hundreds more applications, save money on administration costs, money on power consumption, and offer more computers for less money, then the teachers and staff can deal with a little change". I still tried to be hesitant instead of leaping for joy and said that we should consult with the teachers and staff before making such a change instead of blindsiding them over the summer. Surprisingly when presented to them they seemed to realize that even though this may be some work, we need to make the changes. Now everyone wants to make this a big deal publicly. They now see that this is something they can present to the public to show how "advanced" our school will be and how we are environmentally conscious by using a lower power thin client solution and machines with longer life cycles. They now see this is a positive thing to show parents who pay tuition how we are getting the biggest band for their buck in the area of technology. They will tout our increased application offerings and higher computer to student ratio for less money. We will also be offering connectivity to work from home via FreeNX or VNC for students who are home sick or for doing homework at night. They will be able to provide the same software available at school to students for free. It seemed taking the not so pushy approach and just offering the facts in this case paid off. Our school President has now met with the administrators of all other private schools in our Hiawatha Valley Conference (who our school competes with in sports) and is preaching to them that Open Source is the future and this can help them overcome their budgetary shortcomings while offering more computers and applications. He is trying to convince them to attend the North Central Linux Symposium (www.nclinux.net) and is distributing our fliers to them for us now. Now I just need to be sure it works :-) This is a private school system, and once this is successful and publicly released, the community will put the pressure on our public school system. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

That is the plan. I want to overkill if at all possible. There is no such thing as too fast as far as I am concerned.

The drives will attach to the hot swap backplane. As far as I know every Dell backplane I have messed with only has one connector to go to the controller. So all drives will be handled by a single interface. I can see where there would be a benefit of having the opposite mirror halves on a separate interface, never thought of that. Unfortunately I don't think this is possible with any of the Dell backplanes. I should probably just have an add-in controller on hand just in case the controller would die. > Will your controller handle that many drives? 320 per channel can get > saturated with 4 fast drives working full bore. So the controller > might max out at around 8 drives. I guess I have put my faith in Dell there. This is their fastest single server available (at least that I found). It is supposed to be for high end database applications with large data throughput and a ton of processor usage. Since they build the backplane to handle 10 drives I assume the hardware is meant to handle it. I do have an external PowerVault 220S with 6 drives in it right now and it seems to handle large data transfers well over a single RAID channel. I wish I had a crystal ball and could see into the future to know if it will handle all of the thrashing of a possible 90 concurrent users and maybe even another 60 teachers mounting /home over NFS. If need be I will use my PowerVault as well and put some users on that and some internally, I just want to keep this as simple and self contained as possible. Every time I try and spread services over multiple servers things seem to slow down. > Does NIC bonding work well for you Jim?

As far as file servers go it has worked great for me. I have only tried with 2 nics in the past, never tried 4. With ALB I don't get 2GB throughput on a single connection, but I can get what seems close on multiple connections. If anyone has a good suggestion for how to monitor this I can give a shot at pulling down some hard numbers. > > -64 Bit XUbuntu with LTSP 4.2 (I am thinking XUbuntu will give me some extra speed > I would seriously consider K12LTSP 5.0EL (which uses LTSP 4.2) based > on Centos/RHEL 5 for this setup. Support lifetime and > reliability/support for server grade hardware. I have been going back and forth on this one. I really like the pre-bundled out of the box nature of K12LTSP and the 5.0EL edition gives me the 64-bit support. But I have really gotten used to the extremely large software repository of Ubuntu. Does fl_teachertool work under other distros such as Ubuntu+LTSP 4.2? If not that would be the deciding factor to stick with the packaged K12LSTP. I will most likely build the server both ways if I am still undecided and test, then make a final decision. I will have a month or so for testing before going live. Thanks for the input. I have more to consider.

If we're talking PCIe or PCIx adapters this barrier may diminish or even disappear. Having said that, I've never seen performance numbers for dual-dual adapters in a quad-bond configuration on a PCIx or PCIe bus. It is certainly possible that either configuration would work. Which of them is more scalable, and probably cheaper? Almost definitely the subnet-per-NIC approach. -dhbarr.

I'd expect several dual-nic servers > with isolated client networks to be faster. My tests have been with all servers on a single GB switch. I had a separate SMB/LDAP server which had a 1.5Ghz processor and 1GB of RAM running from a single IDE internally and a single GB NIC plugged into a 8 port GB switch. The test LTSP server was K12LTSP v6 with a Dual 1Ghz Xeons and 1GB RAM running from a mirrored SCSI array locally (running the OS) and single GB NIC connected to the same 8 port GB switch. The /home server is our current file server running Dual 3Ghz Xeon's and 4GB RAM running the os from a internal PERC connected to a PowerVault with 2 36GB SCSI's mirrored, /home on this server is running from 4 300GB SCSI drives in a RAID 5 in the same PowerVault, the file server has dual GB NIC's with ALB and was connected to the same 8 port GB switch. When I would power on a single client (Diskless Workstations Term 150) it would take a little over a minute to power on (around 35 seconds standalone). Once booted menus had a 1-2 second lag and applications took 4-5 seconds longer to open and close. If I use local users and only NFS mount /home The lag is down to about .5 seconds from a standalone. If I get user info from LDAP and used a local /home the lag was also about .5 seconds from standalone. If I used a local /home and a local user base things went as fast as a new local workstation. This made me very nervous to go with a NFS /home and LDAP for users for many clients. When I booted 20 clients to test, the lag did not seem to increase at all in any configuration, but that initial difference was enough to make the system seem (in my opinion) substandard. I want this implementation to seem FAST. If we had already been using this for years the small lag would have probably seemed insignificant. But I don't want to risk a perception of being slow. I know the test servers are less than desirable for a large scale implementation, but for the small test environment this did not seem acceptable. This did not seem normal to me as many users are using SMB/LDAP with NFS mounted /homes and have not complained at all about speed. But maybe that slight 1-2 second lag is insignificant to others.

You wrote that you had 2 dual port Intel 1000MT NICS. I think 1 pair should be built into the MB. They are NOT connected to the PCI bus. They have to be connected to the PCI-X bus or nobody would buy it. The PCI bus can barely support 1 GigE bandwidth. PCI-X or PCIe have much more bandwidth. PCIe (PCI Express) is not as popular in enterprise grade stuff yet cause it's not as mature as PCI-X. Your server must have available PCI-X slots. > > Unfortunately I don't have a good way to test all methods before implementation. > Luckily if the network does end up being a bottleneck, re-configuration of the network > should be fairly trivial. > > Another thought about NICs, 2 of the GB NIC's are actually onboard and the other 2 are a > PCIx dual port card.

That's why I like to use dual interface scsi controllers and build the mirror on separate channels. Seems logical enough. Seems kind of pricey for an extra scsi cable though.

Few more points I wanted to share. Those 8 cores are fed by (share) one 800Mhz FSB memory controller using UMA (Uniform Memory Access). This is where Opteron systems shine. Each Opteron has it's own memory controller. So you would have 4 memory controllers controlling 4 memory banks. However, I am not sure if NUMA (Non Uniform Memory Access) in the Linux kernel works with dual core cpu's. Maybe someone can chime in if they know. But I know 4 single core cpu's would enable NUMA support. >From http://en.wikipedia.org/wiki/Non-Uniform_Memory_Access "Now a system can starve several processors at the same time, notably because only one processor can access memory at a time. NUMA attempts to address this problem by providing separate memory for each processor, avoiding the performance hit when several processors attempt to address the same memory. For problems involving spread data (common for servers and similar applications), NUMA can improve the performance over a single shared memory by a factor of roughly the number of processors (or separate memory banks)." However, the shared memory portion of something like Firefox will still probably use AMD's Hyper Transport bus. BTW, 300GB scsi drives are awful expensive. If you are going to use hardware RAID 10 have you considered enterprise SATA drives and a dedicated PCI-X SATA controller with onboard write back cache (3ware 9550SX or LSI MegaRAID 300-8X). My guess is it would probably be better than the controller that comes with the Dell. Maybe someone who has used those controllers can comment. Just checked the Dell PowerEdge 6800 specs and they have this under the power supply section. "Redundant power is available in all 200-240V configurations and most 100-119V / 120-127V configurations except those that contain or exceed four processors, 32GB memory, five hard drives, and two PCI cards. Redundant power availability will vary by configuration. NOTE: The minimum configuration for most US based facilities is 120-127 Volts." According to this, your setup probably requires too much power to support redundancy. -- 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 brian at portsmouth-college.ac.uk Wed May 9 10:24:05 2007 From: brian at portsmouth-college.ac.uk (Brian Chivers) Date: Wed, 09 May 2007 11:24:05 +0100 Subject: [K12OSN] Centos5 hangs at System Message Bus Message-ID: <4641A145.7030602@portsmouth-college.ac.uk> I've setup a CentOS 5 box with LDAP & Samba using the config files that I've been using on all my other boxes (Mix of FC3, CentOS4 and Suse) and it all seemed to be working until I rebooted.

But after going back and running through the config with the 2x5 backplane I don't have the option for RAID 10. So either they just don't give me a radio button to select, or it isn't possible to spread the RAID across the split backplane. I will call Dell to confirm this.

But I have read so many things that say SCSI is still far superior to SATA for read/write speeds especially when needing to randomly access a lot of data. Also I have seen information that the physical construction of a SCSI drive is still far superior to SATA. I have given Hardware RAID with SATA a try on a few servers where I needed to save a customer money. In my opinion those servers were slower than identical servers I configured with SCSI. Since I can buy SCSI in my price range, I feel safer going with it. Do you really think that the SATA config you suggest would outperform the SCSI?

They don't come right out and state that you can't use redundant, but they say their techs will look at the components and determine whether or not it will handle it. I don't really want to switch to some 200-240v data center config, so I have basically conceded that it will not be redundant. I always buy the 4hr response support from Dell and have had good luck with that. If we go down for 4-6 hours once or twice a year even (which shouldn't happen), I don't think that would be that big of a deal. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

You are the IT guy at a school with 100 thin clients. You have been given approximately $15,000 to build a server setup that can handle all of those clients simultaneously. Your goal is to build the best system you can for the full amount of money. The system needs to come with 3yrs of hardware support on-site within 24hrs or better. You have a single 1GB connection to each lab and network hardware that can put these on dedicated VLANS. The server setup needs to be centrally located (not a server per lab). You have 4 labs to start, in the future you may have 6 labs. You may grow to having to support another 40 clients in the next couple years. In the near future you will add 60 more workstations that just need to mount /home from the server and get authentication information from it. Speed is your goal, this setup needs to be fast....not quick....fast! I have no brand loyalty, but I need to be sure that if hardware fails in a year or two years, I can get replacement parts from the Vendor. I don't want to search eBay or pricewatch for replacement motherboards etc. I would really like to be able to have a central point for using fl_teachertool or similar tool to control users/machines. Also would be nice to have a central point for application updates/installs. What server configuration would you use? Single server, multiple servers, LTSP load balancing, LDAP, shared /home? What network configuration would you use? Teamed NIC's, dedicated VLANS, dedicated physical lans? (Side note, I usually put the server on the LAN with a single IP, I don't usually pass the internet traffic through the server such as the standard setup) What hardware would you put in your server/s? Opteron, Xeon, Quad Core or Dual Core or Single Core, Quad or Dual or Single processors, SATA or SCSI, controller types, quantity of memory, how many NICS? What OS would you run? RedHat AS, CentOS, Ubuntu, Fedora, VMware images of the aforementioned? What LTSP version would you run? 5, 4.2 What window manager would you run? Gnome, KDE, Xfce, etc? Anyone up to the challenge!

I did a quad-bonded Gbit connection from the server to a 24 port Gbit switch. This switch feeds 20 classrooms each with a 24 port Gbit switch. Each classroom has 4-12 thin clients (at 100Mb). The 24 port switch in the classroom was overkill (and they are very noisy as they have fans). I have not seen a network saturation point with this. Note - both dual NICs are on the same PCIx bus. From the client end, the system is screaming fast. The server loading is good most of the time. There are apps that need tuning.

NUMA works with dual cores but it has no effect on a single chip dual core as both cores already access the same RAM bank. Opterons kick some serious bits when it comes to RAM access. During testing prior to the APS installation, I determined that a single chip dual core 2.6 GHz Opteron could perform about 30% faster than the same setup with a dual core 2.8 GHz Xeon. Same hard drives (Ultra 320) and both with 1GB RAM (and both HP servers running K12LTSP 5 beta 9). Using teachertool, I launched 24 simultaneous oowriters. Th Xeons took 71 seconds while the Opterons only required 48. The numbers were more dramatic on a reload (i.e. load, close and reload all 24 to run from cache RAM).

I think what you've proposed is fine, although I'd get a quad-port NIC card or whatever it takes to get an interface per lab rather than bonding them. However one more lab will be about the limit for expanding a system with one monster server. I think it would be easier to deal with a setup with one heavy-duty home/ldap server and a bunch of disposable k12ltsp servers - and you'd be able to upgrade it piecemeal later. > Also would be nice to have a central point for > application updates/installs. You can't get any more central than a single machine... However then you are locked into having only one version when you might want to let one lab test an update before rolling it out everywhere. Doing an 'ssh some_machine yum -y update' is not a big problem, even across hundreds of servers since you can wrap it into a script with whatever set you want to do at once. > What server configuration would you use? Single server, multiple servers, LTSP load > balancing, LDAP, shared /home? A server per lab makes sense to me - and given your gig links to each lab you can put them all in a central location and use a separate network for the nfs-mounted /home. > What network configuration would you use?

(Side note, I usually put the server on the LAN with a single IP, I don't > usually pass the internet traffic through the server such as the standard setup) I only trust things that lots of other people are running with no problem. I don't think a lot of people do software bonding or vlans, so I'd try to have an interface per IP and let the switch(es) deal with everything else. Lots of people do run the NAT/gateway setup though, so I wouldn't expect problems from that and it gives you the advantage of being able to run systems other than thin clients over the same link. > What OS would you run?

I have to say I really wanted to run a massive /home server and a separate LDAP then have all servers talk on a separate gigabit backbone LAN. But the speed thing stopped me. When I did my testing this was all on a Gig LAN and non-production servers. I first had my standalone server, then added LDAP and /home at the same time. When I saw the speed issues I dropped /home and just used LDAP. The speed problem was cut in about half. Then I added /home back on and dropped LDAP for local accounts, speed stayed about the same. So it seemed that each service contributed to about half of my couple second lag compared to standalone. Right now I have the same server serving a small test lab of 15 clients with /home NFS mounted from my current file server but using local unix accounts. I just want to get rid of that 1-2 second lag that I didn't have when everything was local. As far as async goes, I had just used the default /home export config from a k12ltsp server. Here is the export line in my current file server: /home 10.6.0.0/255.255.0.0(rw,no_root_squash,sync) Now I know that exporting to the entire 10.6.x.x network isn't exactly secure, but I don't really care at this point. However I see that the export uses sync instead of async. I also see that the /var/opt/ltsp/swapfiles are exported with async and /opt/ltsp/i386 is exported with sync. What is the difference? If exporting with async is faster why isn't k12ltsp set this way by default? I will try and change my export to async and see if it makes a difference. If it does I will try adding LDAP back to it and see if my speed issues go away. > I'd also try to build a backup system. Backuppc running on a fast > desktop box with a big disk in another room might be good enough but > anything that you can't replace should have offsite copies. I have a 1.5 TB dedicated backup server right now that backs up all servers over the network. I am using Retrospect server for backups at this point, but always remember Backuppc for when it is time to upgrade. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

By having a dual PS, where you need both to function to supply enough power, it effectively reduces your MTBF of your PS. Not good. If Dell is selling dual redundant PS they should ensure the system can work on only one PS.

LDAP should only be checked during login and should take much time if your directory fits in ram on the LDAP server. It might be worth doing a wireshark capture on the authentication conversation to see if there are big delays. You should also be able to run nscd to cache the results but I'm not sure why that would be needed and it can cause some mysterious issues when things change. > Right now I have the same server serving a small > test lab of 15 clients with /home NFS mounted from my current file server but using > local unix accounts.

If exporting with async > is faster why isn't k12ltsp set this way by default? sync means that all writes are flushed to disk before being acknowledged as complete to the client (something that doesn't happen on your local disks...). It is more reliable, but at a big cost in speed and I've never seen much reason to ask a remote filesystem to be more reliable than the local one - and the NFS server is likely to have a better UPS in many settings. I didn't think this should affect startup time much, but perhaps the window managers rewrite some of their setup files. Try some different block sizes in the mount options too, to see if that makes a difference. -- Les Mikesell les at futuresource.com From robark at gmail.com Wed May 9 18:07:38 2007 From: robark at gmail.com (Robert Arkiletian) Date: Wed, 9 May 2007 11:07:38 -0700 Subject: [K12OSN] Just about ready to make a purchase In-Reply-To: <1178724725.3427.26.camel@merlin.localnetsolutions.com> References: <20070508164930.M83264@winonacotter.org> <1178724725.3427.26.camel@merlin.localnetsolutions.com> Message-ID: On 5/9/07, James P.

Here's an interesting review of an 8-way Opteron: http://tweakers.net/reviews/674 Read to the end where they note that some apps ran _slower_ on an 8-way than a 4-way.

Most benchmarks run a single app which then has to do some contortions to spread the work across CPUs. Multiuser servers will naturally be running many copies of applications at once and don't have to do anything special.

Does it indicate that I would be better off with a Dual Quad core machine then > with a Quad Dual core machine? It's not really a "memory access problem". Just a speed issue. However, I just looked up on the web that the Xeon 7100 is the old Netburst architecture. I would vote against the 6800 as it's using old technology. The Xeon 7100 is not using the new Core 2 Duo cores. It's using the old P4 netburst core. That's why the FSB is limited to 800Mhz. Another thing I noticed is that the 6800 is using Ultra 320 scsi whereas the 2900 is using newer Serial Attached SCSI (SAS). The 2900 is using the 5100 cpu's which ARE the newer arch based on the core 2 duo. The 2900 also comes with the option of 667Mhz RAM and 1333Mhz FSB. Faster and more power efficient. Please take my advice with caution Jim as I have no personal experience with any of this Dell hardware. I am just sharing my opinion. If you decide on the 2900 please make sure it will work with Linux. Check the MB chipset, NICs, HD controllers etc. Also I'm not even sure if Linux kernel will work with quad core cpu's yet. Please do your homework. Don't rely on my word. Aha found something about the Intel 5300 Clovertown cpu, >From http://www.phoronix.com/scan.php?page=article&item=585&num=2 "These processors were tested with Fedora Core 6 using the Linux 2.6.18 kernel. At this time there are clocking problems with Enhanced Intel SpeedStep Technology and cpufreq, but the Xeon 5300 series can be ran at full speed by disabling cpufreq from the kernel or manually selecting the higher state." I wonder if the CentOS/RHEL kernel 2.618 has full support for it? This is really new hardware.

I take all advice with caution :-) The more I read, the more I am inclined to go with an Opteron server. Dell makes a 6950 with quad dual core opterons, but it is in a 4U case so there is not as many options for internal drives. However I do have an external PowerVault 220S that can handle 14 SCSI drives and is already populated with four 300GB drives. I could run the OS on some smaller internal drives and run /home on the powervault or run them all in the powervault. I will look more into this tonight. I want to purchase everything within the next week or two, but I think the topics posted here merit a little more research. Dell offers all of these servers with RedHat Linux AS. So I would assume that the 64-bit K12LTSP would run fine on them. I will put a call into Dell to verify.

Opterons have a more sophisticated memory controller architecture than Xeons. Les is correct that Intel has again taken the lead with their Core 2 Duos, but I haven't seem much about those in servers yet and in a multi-user system, I think Opterons still have the advantage. As to SCSI vs. SATA, choose SCSI. Yes, SATA is getting close to SCSI in performance, particularly in single user boxes. And it has a modest ability to reorder requests for optimal seek times. But it's nothing like what SCSI disks can do, and this is particularly so in multi-user systems like an LTSP server where you'll have many people reading and writing to the disks.

I think if you want to go with just a 2x dual core system (4 cores) the Dell 2900 with Xeon 5100 cpus and 667RAM and 1333FSB should be a very good solution. I didn't like the old Netburst Dell 6800 server and I am a little scared of the quad core Xeon 5300 cpu cause it's so new. The 6950 Opteron looks nice but it will probably be louder. Rack mounts are usually louder than towers. Plus as you said it does not have as much storage options. I think it takes a max of 5 drives. Personally, I don't think you really need 8 cores for 90 clients. 4 cores should be enough. So the 2900 with only dual cores should probably be enough. But if you really want more power remember what Les was saying about not putting everything into one box, he has lots of experience. If you had 2 2900's with 8GB ram each, for about 60 clients each, it would offer more room to grow in the future. That's probably what I would do. Get 2 2900's export /home from one of them and use LDAP for auth. It would mean less bandwidth issues and your not putting all your eggs in one basket. Plus more room to grow in the future as you could just add another 2900 for another 60 clients. More choices to consider.... Hope my posts help you make a better choice.

Any usage info you could post and still state excellent performance would be a good benchmark for anyone on the list. There just isn't enough of this type of information floating around (server size + performance + actual number of concurrent users). I know I have seen talk of creating a site in the past about this, does something like this exist? A open wiki for users to post this information to could be very useful. But sometimes it is hard to get the site known about and get people to do so. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

Something similar to tuxmagazine. One that would include articles for all parties involved with FOSS in schools. Both the techy folks and the regular desktop user. We have some good discussion around it and even started a wiki talking about articles and what not. However, after a while things kind of fizzled out. I think we all just got too busy doing are own things and we didn't push far enough. So, I am writing once again to encourage interested individuals to participate in this endeavor. This time a little bit of the leg work and structure has already been done. Going back through the list archives and remembering what happened last time, I think there was too much pressure of people creating the articles in Scribus and no one putting it all together. We can fix this however. My idea this time around is to have a communal blog where individuals can author articles and publish them on the web. Once there are enough articles a few people (who want to) can work on putting the downloadable ezine together. The focus doesn't even have to be on a downloadable ezine either. Having a blog with multiple authors from all tech levels and physical regions would be a great resource for everyone involved with FOSS in schools. There was some good discussion last time so I think there is a niche for something like this. So to get this thing started I have done some leg work (which is up for discussion as well). Doing this the easiest way, I created a blog at wordpress.com. http://theopensourceeducator.wordpress.com/ (soon to be www.theopensourceeducator.org). Wordpress is both easy to use and pretty powerful to boot (GRUB of course, ha, bootloader joke). I have also created a google group for discussion about TOSE and issues around FOSS in education. http://groups.google.com/group/tose/. Again, I used googlegroups because it was easy. I like easy. I think that is a good thing here. We also have the wiki that Dave Trask set up last time around. I would suggest looking at that to see where we got to last time. http://www.vcsvikings.org/tose/doku.php Please come and discuss how we get this project of the ground. I will also be posting this to the Edubuntu list. Any others are welcome. Feedback is very welcome. Tim Hart Glenburn School -------------- next part -------------- An HTML attachment was scrubbed...

This could be very cool. There is an endless amount of topics to cover even if this was narrowed to FOSS in education. I could see an article being created fairly easily just from my last string of posts about what types of servers to buy along with advantages/disadvantages to certain configs. If such a thing was created I could see distributing it to admins and techs in our school districts to help them see the light. I don't think I have the best technical writing skills or even a good ability to design page layouts and such. But I would be more than willing to try or even just offer suggestions for topics. All the input wouldn't just have to come from users on this list either, once something was established I am sure others would find their way there. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

So if anyone > is running Windows apps in Linux please respond! Crossover works very well for the list of supported apps. If they are not in the list of supported apps then it is fairly hit and miss, mostly miss. Some things will appear to run but have a glitch not seen at first (might crash only when printing). I downloaded a beta of the newest crossover 6.0.3 (I think that's the version) and it is pretty nice with an ever growing list of supported apps. Codeweavers will work on fine tuning apps for you but this isn't free and they are pretty busy. I had some email conversations with Jeremy White last week and they are backed up for a few months (depending on what is crashing and the availability of the code writer assigned to that arena). Still I would give them a look, the supported stuff runs without a hitch and they support LTSP environments. Jeremy is also very good to deal with and is more than willing to give out software versions to try and see if CrossOver is a good fit for your organization, he just doesn't want too many calls on issues with the trials :-) Don't know much about Win4Lin and my Wine experience has been less than desirable.

Specifically, I got some windows-only inventory management software running for the company I work for (it's called MAS 200). The latest version is 0.9.36, so see if you can get a hold of that version to try out. It's free, so it's probably worth your while. If your application doesn't install properly, try changing the version of windows that wine emulates. This is done with the winecfg gui. Recently when installing Acrobat reader (the windows version was required for MAS 200 to install), I found that version 6 would only install when wine was emulating win98, but after the installation it would only run when wine was emulating win2000. -Rob On Thu, May 10, 2007 at 03:38:58PM -0700, Cody Grosskopf wrote: > I've recently been in the market for some new software to run my Windows > apps in Linux.

I've installed this version on 3 different machines, using the CDs, and so far everything has worked well. (Of course that's no excuse for the dvd not working....)

Load up squid proxy for caching!! That will do a lot for reducing the load on the feeble WAN connection. 2. I just loaded a dual-homed server using the following script to provide dual access to 2 WAN connections and load balancing between the two connections. Note: eth1 and 2 are WAN and eth0 in LAN. This machine acts as a router (and also has web sites hosted on both WAN IPs. The only "gotcha" is the LAN can't "see" the web sites on the router machine.

Robert, I took the boot.iso from dvd image, nfs exported the directory with the dvd image and the install went fine. nfs seems to be much faster than cd/dvd load anyway. julius From lnkemp at bolivar.k12.mo.us Fri May 11 03:40:56 2007 From: lnkemp at bolivar.k12.mo.us (Kemp, Levi) Date: Thu, 10 May 2007 22:40:56 -0500 Subject: [K12OSN] Which .NET for Linux - Windows Apps in Linux References: <51205.192.168.254.3.1178851500.squirrel@www.eazylivin.net> Message-ID: I didn't want to change the topic so I started a new thread but, I know from recent experiance that Reading Counts, Scholastic Reading Inventory and Management Suite won't work with Wine or Crossover. We went with RDesktop for those, and then Seamless RDP as well. It was working nice, then I did some research on the software itself and discovered Renaissance Place. It's a web version of Accelerated Reader, all you need is Java, Flash, and .Net. My question is which .NET would any of you reccomend? DOTGNU or MONO, I don't see a difference. I'm really happy I convinced the new librarian to switch to this next year, now I need to make it work. All three schools will be using one app (finally), which means one server for me, and multiplatform use. Going to be a long summer, the reading app will need a web server, the library app is becoming a web app, and the student information is becoming a web app. Seems like the only thing students and teachers will run local might be office suite software. Yea central management!

RIght now pam_mount creates shares for the teacher and the student for every domain user logging on. So the log on process is delayed slightly. But logons are still only <10 seconds, which is about 10-20 seconds faster than my XP machines (with Roaming Profiles and Deep Freeze...) usually! Also, my script seems a little primitive.

I usually upgrade a good 8-10 months after a release.. That way, I can enjoy most of the bleeding-edginess of Fedora, but still have the stability of months of patches before upgrading.

All the stations just get 100MB, but that's fast enough. Our internet access most likely isn't fast enough to handle running a lot of web apps from off-site. We currently have 3 T1 lines, another 1 T1 dedicated to a distance learning lab which will be combined with the other 3 soon, and I think we're going to purchase another. And they still complain about the speed. It's has come to the point where we have to block streaming video sites, unless they are allowed to download for later viewing, ie.

The client requires something called "RLI print plugin" I doubt it has a linux version, but I could be wrong. I'd personally avoid anything that required .NET on the client. Educational apps should be built on open standards. What's wrong with LAMP or J2EE backends with a web/AJAX front-end?

We went with RDesktop for those, and then Seamless RDP as well. It was working nice, then I did some research on the software itself and discovered Renaissance Place. It's a web version of Accelerated Reader, all you need is Java, Flash, and .Net. My question is which .NET would any of you reccomend? DOTGNU or MONO, I don't see a difference. I'm really happy I convinced the new librarian to switch to this next year, now I need to make it work. All three schools will be using one app (finally), which means one server for me, and multiplatform use.

Subject: Re: [K12OSN] Which .NET for Linux - Windows Apps in Linux I believe .NET is just for the server Renaissance Place. The client requires something called "RLI print plugin" I doubt it has a linux version, but I could be wrong. I'd personally avoid anything that required .NET on the client. Educational apps should be built on open standards. What's wrong with LAMP or J2EE backends with a web/AJAX front-end?

But, before I can do the expansion, I need to come up with a way to copy Firefox Cache from each account to a single folder for his inspection. I was thinking that a script could do the job. Let me demonstrate what the script should do. get this /home/P042024/.../cache/somefilename to this /somefolder/P042024somefilename.jpg Do it for every account on the server. Scan all the home folders, find firefox cache and attach the account name to the beginning of the filename and attach ".jpg" to the end. Maybe add to copy only files that are within two weeks If I can get something like that and demonstrate it then I have the green light to expand Linux usage in out Library. You know I'm have a Deja Vu moment. I thought I'd posted something like this before but I couldn't find it in the archives.

It does not have the scalability of the full version of SQL Server 2000. MSDE is suited for most school-level and classroom-level installations, and may be sufficient for smaller districts. Larger district installations will require upgrading to a full SQL Server 2000 license. I saw this on another listserv about getting firefox on linux to work with Accelerated Reader, I've never tried this. I have finally figured out how to make renplace run under linux. Install all available required plugins for firefox under linux. This will not work from the renplace software requirements check since it gags on non-support browsers. Apparently doesn't like acrobat reader 8 either. But no big deal. Get 'em from their respective vendor's websites. Next, get the user agent switcher plugin for firefox: https://addons.mozilla.org/en-US/firefox/addon/59 And the additional user agent "disguises": http://techpatterns.com/forums/about304.html Set the user-agent switcher to multizilla (xp). Voila it works, and doesn't whine about missing plugins, etc. I have a 5mb swf animation of it working on my home workstation (CentOS 4.4) if anyone is interested.

I think the VMware-server-1.0.3-44356 build incorporates at least some of the vmware-any patches. I've never had any trouble under CentOS or the CentOS-based k12ltsp before, although I have needed the patch for fedora.

What windows apps are you wanting to run via Linux? The key to running windows apps with wine,, if you are wanting to have all users access is to make a "wine" directory then copy all the install wine/windows apps to this directory,,,then make a launcher as root then push to desktop for all users( if this is what you are wanting)..

I am having a little trouble understanding exactly how 32-bit apps function on a 64-bit system. Say you have a 64-bit system running a 64-bit OS which are able to fully utilize processing power and RAM, how does the implementation of 32-bit apps affect performance? To be more specific if a 32-bit app is running on this system, is the app limited to accessing only 4GB of RAM, or does it communicate with the OS and the OS can still make full use of the RAM? I don't know if my question is making any sense but if someone could shed some light on what limitations 32-bit apps on a 64-bit system have I would appreciate it. I guess I don't really know how many of the standard educational apps that would come with a 64-bit K12LTSP would be 64-bit or 32-bit. I assume that Firefox and OpenOffice are 64-bit, but I am trying to imagine what limitations I'll run into when calling on a 32-bit application or plugin. Say I install Google Earth or KStars, what will those run at? A little confused as to how to track this info down.

I set the firewall to be on, allowing port 22, and set SELinux to warn. The installation ran fine, but when I tried to boot a client, it hung at the tftp stage. I noticed iptables had no rule for port 69, so I added that. Then the client hung when trying to NFS mount /. Turned iptables off, and the client boots right up. This is a single NIC machine, and I used the default settings for everything except the subnet, which I set to 192.168.23.0. The dhcpd-k12ltsp.conf, exports, and lts.conf file all adapted correctly. I notice that in /etc/sysconfig there's a iptables-k12ltsp file that seems to suggest allowing everything on eth0 (if memory serves; I'm not at the machine at the moment). But if so, it didn't take. I'll go back and rebuild the iptables file manually, but I'm not sure that's supposed to be necessary.

I'd say the error message is not the result of the for loop, but of the ls statement. You could suppress the error by redirecting standard error to /dev/null: ls /home/$account/.mozilla/firefox/*.default/cache 2>/dev/null > I plan to run it as a cron job > but I don't want the error messages popping up on the screen. Is there a way > to suppress the error message? Will putting it in a cron job log the error > but not display it? I believe by default any output generated by cron jobs is mailed to the user the script runs as. You can override the address by setting MAILTO= in the crontab. You can also redirect all output of the cron job to /dev/null: /path/to/script >/dev/null 2>&1 You can find more information on I/O redirection here: Nils Breunese. -------------- next part -------------- A non-text attachment was scrubbed...

So I will see if I can get a login after the install of the plugins. We host it here, and are planning to do so for the other two schools. By the way the elementary here is divided, k-2 3-5, and the other schools is the middle school, 6-8. So I should be going k-8 with this app. And if it works we will be spreading out more K12LTSP labs soon. I know my boss wants to, but not the other tech. I'll let you know if I get it working.

The version of vncviewer included in k12ltsp supports the '-via ' option so you can give the ssh target (which doesn't have to be the same machine but it can be) and it sets the tunnel up transparently: vncviewer -via gateway remotehost gives you a vnc connection to remote host which may be behind a firewall with only ssh access to the gateway machine permitted through.

Register today! Message-ID: NOTE: The UNH Registration is now active! Visit http://www.fossed.com to register! Also...help us spread the word! Blog this! Post this! Forward this! Go nuts! :-) Hi folks! Hard to believe, but NELS/FOSSED 2007 at Gould Academy is only a month away! UNH follows soon after and Gallaudet will come up quickly in August! This year is shaping up to be fanatastic! But....we need YOU! Come and join your colleagues for 3 days of hands on learning about Linux, Open Source, and technology in the school and classroom! The atmosphere is relaxed....the food incredible...and the presenters are fantastic! (and we've just received word that the awesome Daryl Hawes of Apple will be joining us again as our Moodle instructor as well as Open Source for Macs...Daryl has always gotten rave reviews for his presentations) Bryant Patten is the man who literally wrote the book on Open Source Apps for your classroom. He'll be presenting and showing you many of the applications and how they can help you with integrating technology in your school or classroom. Most of the apps are completely cross-platform as well! Not only that, the fine folks at PRCTech will be printing and providing copies of the book for all of you to take home! We have some fantastic classroom teachers like Deb White who'll be sharing their experiences with you. Sharon Bett's, Maine's very own Web 2.0 guru, will show you all about the many tools available online to help you take things to the next level with your classes. This session was very popular last year at both Gould and UNH. Gideon Romm will be on hand to show you all about LTSP and Edubuntu. Matt Oquist will show you how to integrate your Linux network with your Windows network and vice versa...and we have several more presenters who I'll introduce to you in the weeks ahead. We also have some fantastic guests and keynotes lined up! Most important though....is YOU! This conference began 5 years ago at the request of several school tech folks from Maine who simply wanted to learn more about Linux and Open Source. From this request, NELS was born. Here we are 5 years later :-) New this year is the addition of a FOSSED/NELS conference at Gallaudet University in Washington D.C.! Join us in the nations capitol August 5th - 8th for this exciting conference! Everything is included! Meals, rooms, and a great conference! Registration is simple. Visit the http://www.fossed.com site....and on the right under Main Menu....click the registration link for Gould/Gallaudet or UNH. Even if you don't have the financial details worked out...register anyway and we can take care of the rest later. The most common method of payment is by purchase order, but we can accept checks as well as credit cards (if you wish to pay be credit card for Gould or Gallaudet....please email me (copperdoggy at gmail.com) and let me know...and I will send you the link to make the secure transaction). Register soon! So...register as soon as possible....I need to get some numbers firmed up as soon as I can. We're always open to suggestions....if you have any ideas....anything you want to learn....let me know! Any questions...also let us know. I'll answer them all :-) Hope to see you this summer!

Hi John, We're using bind for all our DNS and dhcpd for all our DHCP, and we have three AD networks that are working fine. We configured bind to accept updates from the AD servers' IP addresses, and we've been ignoring the fact that the XP clients want to register dynamic DNS entries. I know this should supposedly be breaking some kerberos requirements for correct forward and reverse lookups, but we haven't noticed any problems, and we've been running this way for two years. --matt -- Open Source Software Engineering Consultant http://majen.net/ From william at fragakis.com Tue May 15 17:23:38 2007 From: william at fragakis.com (William Fragakis) Date: Tue, 15 May 2007 13:23:38 -0400 Subject: [K12OSN] Which .NET for Linux - Windows Apps in Linux In-Reply-To: <20070515160024.F1D72737C0@hormel.redhat.com> References: <20070515160024.F1D72737C0@hormel.redhat.com> Message-ID: <1179249818.10084.6.camel@server.ltsp> We've been using RenPlace under K12LTSP for two years.

If strftime is anything like it's C counterpart, it works in localtime anyway so all you have to do is export an appropriate TZ setting in the environment before running. If you are running a command line program you can just put the assignment ahead of the command like: TZ=EST5EDT date TZ=CST6CDT date But, shouldn't ical items be in UTC? -- Les Mikesell lesmikesell at gmail.com From dyoung at mesd.k12.or.us Tue May 15 23:09:27 2007 From: dyoung at mesd.k12.or.us (Dan Young) Date: Tue, 15 May 2007 16:09:27 -0700 Subject: [K12OSN] OT: scripting help In-Reply-To: <464A36DD.2020603@scheie.homedns.org> References: <9bd317560705150703s7aea89a4q208497456180eceb@mail.gmail.com> <464A36DD.2020603@scheie.homedns.org> Message-ID: <464A3DA7.3050708@mesd.k12.or.us> Peter Scheie wrote: > I'm no python wizard, but it seems to me that problem is that strftime > is a string formatting method, and you want to add an integer to that > string, which doesn't make sense to python.

Yeah, strftime returns a string, not an integer. strftime (part of the time module) should return localtime by default. What do you get if you change it to (just for testing): return value.tzname Maybe localtime is reset to UTC in SchoolBell... -- Dan Young Multnomah ESD - Technology Services 503-257-1562 From jschubert at shaw.ca Tue May 15 23:32:32 2007 From: jschubert at shaw.ca (Jeremy Schubert) Date: Tue, 15 May 2007 17:32:32 -0600 Subject: [K12OSN] School printer server Message-ID: <000001c79749$4f47c9a0$edd75ce0$@ca> I'm looking for a very simple print server to set up at an elementary school (approx 50 workstations).

I do this all the time. BTW, if you're looking for something that doesn't use terminal services, then while you certainly can use K12LTSP for that, you don't *have* to. Any GNU/Linux or *BSD system that has CUPS will work just fine. I've used CentOS, Debian, Slackware, K12LTSP 4.2EL, Ubuntu, Yellow Dog Linux--even FreeBSD at one point.

Hope this helps you from banging your head against the wall. Checklist: 1) make sure that your firewall opens the proper ports starting from 5900, say, 5900:10 you can add this line to /etc/sysconfig/iptables -A RH-Firewall-1-INPUT -p tcp -m tcp -m state --dport 5900:5910 --state NEW,ESTABLISHED -j ACCEPT and restart iptables 2) make sure this is the first line in /etc/hosts (actually, check this first) 127.0.0.1 localhost.localdomain localhost for some reason, a couple of my servers didn't have the complete 127 address on that line, it was truncated. 3) remember that you are using vncts, not vncserver. ie don't start vncserver under System -> Administration -> Services, you don't need it. On ver. 6, it's hidden in the "On Demand Services" tab. regards, William On Wed, 2007-05-16 at 12:00 -0400, k12osn-request at redhat.com wrote: > > Message: 13 > Date: Tue, 15 May 2007 21:32:46 -0400 (EDT) > From: Tom Wolfe > Subject: [K12OSN] VNC grey screen > To: k12osn at redhat.com > Message-ID: > Content-Type: TEXT/PLAIN; charset=US-ASCII > > Hi folks, I tried recently to connect to my k12ltsp 6.0 server via > VNC.

I think it's the idea that the local hard drive gets locked up in their office at night, so they think it's more secure for their private files. In a way they're right. I could read anything I want to that's on the server (with root / administrator rights), but I'd have a hard time accessing a hard drive that's in a locked office. Not that they're trying to protect their data from me, but they understand lock-and-key security better than network security. -Rob From rowens at ptd.net Thu May 17 00:53:25 2007 From: rowens at ptd.net (Rob Owens) Date: Wed, 16 May 2007 20:53:25 -0400 Subject: [K12OSN] local devices - PCMCIA In-Reply-To: <464B9569.9020400@scheie.homedns.org> References: <20070516012859.GB13310@clubber.owens.net> <20070516221027.GC15055@clubber.owens.net> <464B9569.9020400@scheie.homedns.org> Message-ID: <20070517005325.GB15444@clubber.owens.net> I've read that wiki page.

I have a room full of Dell GX1 computers. According to Dell's specs, and as confirmed with a Knoppix live CD, the sound chip is a CS4236. I have changed my lts.conf to reflect this. here's the relevant section: # enable sound by default SOUND = Y # choose either esd or nasd to be the default (esd only on x86_64) SOUND_DAEMON = "esd" # SOUND_DAEMON = "nasd" # default sound volume VOLUME = 75 ### For ISA sound cards, you have to specify the module to use: SMODULE_01 = "snd-cs4236" # io=0x220 irq=5 dma=1" I don't know the io and irq for the card, which is supposedly PnP. The error the clients get at boot is: /dev/dsp: no such file or directory There is no /dev/dsp directory. I have various sound apps installed but obviously they are not working. Help!

In our country there is a rapid development of an ID-card (electronic identification) and as a library we need to keep up with the flow in order to serve our readers etc. (Electronic elections for example) For now I have tested serveral situations but results are the same : When I connect the card-reader to the server it shows that we have it connected and can somehow get some pupups for entering code. However if I connect the reader to the client nothing happens. Is there some kind of tutorial, manpage or something else that could help me to develop smart-card reader support in out terminals ? What config files should I change in order the clients understand that they have USB card-reader connected not regular USB stick ?

I'm moving all my users to printing to the queues on this server (both Windows, Mac, and Linux). You should follow the instructions for using the CUPS/MS postscript drivers so you can easily deploy to Windows clients using a login script. The CUPS/MS drivers don't need local admin access for the user to use the queues.... So no more adding special printer drivers to each client for each printer... they all use the same CUPS/MS drivers. The next step for me is to use pykota. I've got a central view of all the print jobs now so I can see if something is jammed.

Extremely private data ought to be anyways. That solves both problems. -------------- next part -------------- A non-text attachment was scrubbed...

You should follow the instructions for using the CUPS/MS postscript drivers so you can easily deploy to Windows clients using a login script. The CUPS/MS drivers don't need local admin access for the user to use the queues.... So no more adding special printer drivers to each client for each printer... they all use the same CUPS/MS drivers. The next step for me is to use pykota. I've got a central view of all the print jobs now so I can see if something is jammed.

They believe the client server approach is still the best way to go. Of course by client they mean windows or mac. I don't they will go full web app with it, which is ridiculous because most of the use will always be on a local intranet with higher bandwidth than the Internet. Having it as a web would just make it more universal for the clients and allow the occasional home user access if you even made it available externally. Good luck with it though, I've got to wait till our librarian retires next week to return our copies, she also made a rash decision without consulting the new librarian or anyone actually. I'm lucky scholastic is actually going to take it back. The principal was excited when he heard the library had that much budget left, we're instead going to buy a mobile smartboard. Much better use of the money if you ask me. Levi On Thu, 2007-05-17 at 16:36 -0400, James P.

Sorry, I should have been more descriptive. They have the FUSE /kernel module/ disabled. External kernel modules are, uh, interesting to build, as I understand it. Probably not for the weak hearted. They need to match the running kernel, so every time the kernel is updated, you need to rebuild the module. I thought I heard that ATrpms is building said kernel module. Google pointed me to this: http://atrpms.net/dist/el5/fuse/ CentOS has occasionally built kernels with options turned on that aren't on in the RHEL kernels (Appletalk comes to mind). Don't know if they'll do the same for 5. -- Dan Young Multnomah ESD - Technology Services 503-257-1562 From staffords at glenburn.net Fri May 18 12:03:18 2007 From: staffords at glenburn.net (Shane Stafford) Date: Fri, 18 May 2007 08:03:18 -0400 Subject: [K12OSN] OpenBiblio and what on a server?

I tried downloading and installing a fuse rpm from the rpmforge repo (atrpms was down at the time). However, there are too many dependencies on the existing .fc6 fuse-libs rpm and I'm nervous about using the --force option to ignore these dependencies. (I can remove the .fc6 fuse rpm, but the .el5 fuse rpm won't install unless I remove the .fc6 fuse-libs rpm. yum wants to remove the following as dependencies of fuse-libs: ltsp_esound_i386, ltsp_esound_server, ltsp_i386, ltsp_i386-boot, ltsp_ltspfs, and ltsp_x_vesa) Eric, if you're listening please let me know if there's anything I can do to help fix this. I'm not a programmer, but I know my way around a Linux system pretty well.

Subject: Re: [K12OSN] fuse problems on 5.0.0EL -- Bug confirmed Sorry, I should have been more descriptive. They have the FUSE /kernel module/ disabled. External kernel modules are, uh, interesting to build, as I understand it. Probably not for the weak hearted. They need to match the running kernel, so every time the kernel is updated, you need to rebuild the module. I thought I heard that ATrpms is building said kernel module. Google pointed me to this: http://atrpms.net/dist/el5/fuse/ CentOS has occasionally built kernels with options turned on that aren't on in the RHEL kernels (Appletalk comes to mind).

I tried downloading and installing a fuse rpm from the rpmforge repo (atrpms was down at the time). However, there are too many dependencies on the existing .fc6 fuse-libs rpm and I'm nervous about using the --force option to ignore these dependencies. (I can remove the .fc6 fuse rpm, but the .el5 fuse rpm won't install unless I remove the .fc6 fuse-libs rpm. yum wants to remove the following as dependencies of fuse-libs: ltsp_esound_i386, ltsp_esound_server, ltsp_i386, ltsp_i386-boot, ltsp_ltspfs, and ltsp_x_vesa) Eric, if you're listening please let me know if there's anything I can do to help fix this.

All the printers are over the network.... either jet direct, thin-client run (with or without a monitor), and even off windows XP desktops (I'm stuck with AD, so I use group policy to control the firewalls of all the XP desktops and make it so file/printer sharing is enabled to the print server (sputnik). The funny thing is those with local windows printers sometimes are being redirected by the login script to the queue on the server and then back to their own printer... which is fine so I can see how much they print. =) It takes a little while to get the drivers put together to make the CUPS/MS printing work, but once you do that, you never have to install funny MS drivers to the print server so they can be automatically installed on the windows clients. You do have to run a command called cupsaddsmb whenever you add a new print queue for it to show up in samba, but you just wait 5 minutes then run it, and voila! You've got printers windows can use easily!

I apologize if you have already answered this but I am just now following this thread and didn't see the original email. The top and bottom panels are 'gnome-panel'. It's quite obvious they aren't running but one thing you can do is in a shell is type 'ps -ef | grep gnome-panel' without the '' and see if gnome-panel returns. You can also try to manually start gnome-panel by issueing the following command '/usr/bin/gnome-panel'. That is a assuming gnome-panel is in the same path in Ubuntu as it is in Fedora. If it's not, you can use 'whereis gnome-panel' to locate the file.

I apologize if you have already answered this but I am just now following this thread and didn't see the original email. The top and bottom panels are 'gnome-panel'. It's quite obvious they aren't running but one thing you can do is in a shell is type 'ps -ef | grep gnome-panel' without the '' and see if gnome-panel returns. You can also try to manually start gnome-panel by issueing the following command '/usr/bin/gnome-panel'. That is a assuming gnome-panel is in the same path in Ubuntu as it is in Fedora. If it's not, you can use 'whereis gnome-panel' to locate the file. If this is just one user it could be a corrupt profile as well. /paul -----Original Message----- Sorry Matt, No luck.

If one of them has dhcpd stopped, then dynamic clients don't get an IP address. I think the static addresses still work. In /var/log/messages it says peer holds all available leases. I was wondering why most of the computers in one classroom (the only classroom I hadn't setup static ip addresses for all clients) suddenly stopped getting ip addresses. I restarted dhcpd on the other server and it started working again. This doesn't seem good from the failover perspective. It means that if one server goes down so does dhcp. Has anyone else observed this? As a side note. I had another problem in that class, because I accidentally gave 2 computers the same ip address.

If your test phase would permit it, I can attest to the functionality of CentOS 5's load balancer. It's actually pretty darned good and even compares favourably to F5's BigIP box. Doesn't take that much of an expert to set up, just some reading. My setup, which includes two load balancers in failover configuration, was done in three days, and that includes the study/learning time, since I'd never actually set up a load balancer in my life before. Now, I can do it in less than an hour; if I add failover, that's an hour and a half.

Everything works as expected on the Windows side, but the password expiry doesn't seem to work on the Linux side. Users get no notification that their password is about to expire. In fact, they get no notification that their password has expired, and are even allowed to log into the Linux desktop with the expired password. When they try to access an NFS or SMB share they're denied access, but with no indication that it's an expiry issue. Is there a way to get a more uniform behavior between the two systems?

In-Reply-To: References: Message-ID: OK, NECC is coming up (June 25 - 27 in Atlanta), and this is a combination of a status report and a call for volunteers. Please forward this email to your Free and Open Source Software friends! NECC is the National Educational Computing Conference (center.uoregon.edu/ISTE/NECC2007), and it attracts over 15,000 educators each year. It's arguable one of the largest (if not the largest) educational technology shows in the world. For the last several years NECC has supported an "Open Source Pavilion" (apologies to Richard Stallman) with an Linux thin-client lab for demonstration purposes. Last year we added a speaker series, which is now a part of their main program. This year we are getting our own large room (!!) and adjacent hallway space. Hurrah! This year's speakers can be seen at our organizing wiki: http://necc2007.wikispaces.com/Speakers. There will also be two "Birds of a Feather" sessions on FLOSS: http://necc2007.wikispaces.com/Birds+of+a+Feather. OK. Now, about getting help! We could really use: 1. Setup volunteers. We'll set up the lab and computers late Saturday afternoon / evening (June 23). Maybe we'll get some pizzas and make it a party. 2. Volunteer for "milling around" Monday through Wednesday (25th - 27th). The Open Source Pavilion needs folks who'll just answer questions (mostly really basic) about what FLOSS is. Come for an hour, or come for three days. 3. "Playground booths," same three days. These are 5 - 10 stations where we'll be demonstrating different FLOSS programs. Previously we've showcased OpenOffice, GIMP, Audacity, Linspire, SchoolTool, Edubuntu, Moodle, Firefox, and Knoppix. We're open to just about anything that you'd like to demonstrate that will give our attendees some good hands-on, one-on-one demonstrations. If you can bring your own computer, that helps, but if you can't just let us know. We also welcome proposals from commercial vendors who will commit themselves to also supporting the FLOSS ideals and helping out in general. You can go to the wiki (http://necc2007.wikispaces.com) to sign up to volunteer or send me and email letting me know what you can do.

OK, I'm an idiot. That shows that SDL itself was updated on May 15th, which fits the timeframe perfectly. (from the log) May 15 06:22:23 Updated: SDL.i386 1.2.9-6 So, what's the best solution? Do I need to yum remove that and install an older one from RPM? Is there a "yum way" to do that? Should I file a bug with the SDL people? (Whoever they are?) Man, it would be really cool if there was a "yum downgrade foopackage" command. I'll start googling now, but I'd appreciate any suggestions. I always feel like there's a million ways to troubleshoot linux problems, but no clear "best" method. Thanks again. Viva la Linux libre and K12ltsp. ck PS - Is it risky to turn nightly Yum off on a production box? It seems risky to leave it on, because stuff like this happens, but is it analogous to not running update on a windows box, in that I'm leaving myself open to security vulnerabilities?

I think it's risky to leave it _on_, personally. Some daemons misbehave after an update in my experience (Samba and CUPS come to mind); other updates ought to be followed by a reboot (kernel, glibc). I'd rather know what the updates are, apply them judiciously, and test the associated services posthaste. I've done a silly little shell scripts like this (run out of cron) for this reason.

I would argue it is more risky to have auto-updates running with Linux stuff. Once the server is doing what it is supposed to, _only_ update for security reasons and then do it after a test and have rollback available. Sometimes a security patch is not relevant to the operation of the server you use so it can be ignored for a while. Other times, the security issue can mitigated by other means until the upgrade has been verified as ready for use in your configuration. The short answer is turn off yum updates on a production box. -- James P.

AFAIK, the yum developers believe there is no universally safe way to downgrade RPMs (specifically, backing out scripted actions). You can get most of the way there with: rpm -e --nodeps SDL yum --disablerepo fedora-updates install SDL Disabling the fedora-updates repo will give you the version that shipped with the initial FC-5 release. -- Dan Young Multnomah ESD - Technology Services 503-257-1562 From jkinney at localnetsolutions.com Mon May 21 17:50:39 2007 From: jkinney at localnetsolutions.com (James P.

First, I ran updates on both our K12LTSP6 server and on the test Ubuntu fat client. On K12LTSP6 thin client: GConf2-2.14.0-8.fc6.src.rpm gnome-panel-2.16.3-2.fc6.src.rpm On Ubuntu fat client: gconf2-2.18.0.1-0ubuntu1 gnome-panel-1:2.18.1-0ubuntu3.1 Test: Create new smbldap user (user-x). Login as user-x from Ubuntu fat client. Gnome-panels show up :-) Everything looks good. Logout of Ubuntu fat client. Login as user-x from K12LTSP6 thin client. Gnome panels show up, but are different than normal, panel launchers are replaced by question marks. Logout of K12LTSP6 thin client. Login as user-x from Ubuntu fat client again. Gnome panels show up, desktop floppy icon appears. Now, how do I sync the two so both are using the same gconf2 and/or gnome-panel. --Peter Matt Oquist wrote: Do you have users logging into two different versions of Gnome? That's not the desired situation, and (without doing any precise verification) I believe having different gconf versions can lead to exactly the sort of situation you're describing, where logging into one version leaves you with no panels, while the other one works fine. In order to get around this problem in one of our schools, we just upgraded all the fat clients and the terminal servers to the same release of Ubuntu, and then left them alone. That took care of the issues we had been having with broken desktop configurations. What happens if you log in for the first time, as a brand new user, on a thin client? Then go log into a fat client -- how does that work? --matt -- Open Source Software Engineering Consultant http://majen.net/ Shape Yahoo! in your own image.

If it's appropriate (and if not, thanks for listening), I was wondering if anyone would be kind enough to take time out of his/her busy day to help me with a shell script (which I have little experience writing, unfortunately, but I'm learning) which I need asap. Here's the scenario: Our company copies a data file from Fileserver to FTPserver. A business partner picks up that file from the FTPserver at a specified time and, with 10-15 minutes, returns a reults file. The results file is then copied to Fileserver, where it's made available to our business application. Finally, files older than 1 day are deleted from FTPserver. What I'd like to do is confirm that an exact copy is made from FTPserver to Fileserver before deleting the old files, But, I don't know how. Here's my script, simple as it is, so far: #!/bin/bash #Declare our variables FILENAME_PARTNER="partner"`eval date +%Y%m%d`".csv" FILENAME_OURCOMPANY="ourcompany"`eval date +%Y%m%d`".csv" WORKDIR=/home/partner DAYSOLD="1" #Virus scan all files in Partner ftp directory bdc --log=/var/log/bdc.log --disinfect $WORKDIR > /dev/null 2>&1 #Change ownership and permissions of Ourcompany files to go to Partner chown partner $WORKDIR/$FILENAME_OURCOMPANY chgrp partner $WORKDIR/$FILENAME_OURCOMPANY chmod 770 $WORKDIR/$FILENAME_OURCOMPANY #See if Partner file has been uploaded.

What's wrong with: > > rsync -avP -e ssh /foo root at dest:/foo && rm -f /foo You have to run it per-file that way - and know the filename. I usually do whole directory trees or wild-card filenames and would often like it to be interruptible and pick up where it left off when you restart it. For example, to gather web server logs from a farm of servers to one place I use a wildcard filename in the rsync request, then after the run completes I have to expand the filename list in the receiving directory and ssh a command back to remove those files. This works, but only because the names are date-stamped and unique. It would be a lot cleaner if rsync had the option to do it as soon as it knows the transfer is complete and successful. -- Les Mikesell lesmikesell at gmail.com From rowens at bio-chemvalve.com Wed May 23 16:12:06 2007 From: rowens at bio-chemvalve.com (Rob Owens) Date: Wed, 23 May 2007 12:12:06 -0400 Subject: [K12OSN] graphics problems w/ multiple SCREENs Message-ID: <29AEB552E5D40645BA38E82F0939CB08291FB8@MAIL-EXCH.bio-chemvalve.com> I'm running K12LTSP 5.0.0EL SCREEN_01 = startx SCREEN_02 = rdesktop -f -a 16 10.xxx.xxx.xxx SCREEN_03 = shell All screens work fine, but if I log in to the Windows terminal server on SCREEN_02, then go to SCREEN_01, then back to SCREEN_02, the graphics are unreadable on SCREEN_02.

(the default for newer versions) uses the same underlying ssh authentication mechanisms as scp - or an interactive ssh session for that matter. If you have set up ssh key authentication for passwordless access, rsync over ssh will work too. -- Les Mikesell les at futuresource.com From dyoung at mesd.k12.or.us Wed May 23 16:23:34 2007 From: dyoung at mesd.k12.or.us (Dan Young) Date: Wed, 23 May 2007 09:23:34 -0700 Subject: [K12OSN] Way OT: scripting help In-Reply-To: <200705231215.42989.dyioulos@firstbhph.com> References: <200705221544.09931.dyioulos@firstbhph.com> <465379A8.3030704@futuresource.com> <46545AE5.5000502@mesd.k12.or.us> <200705231215.42989.dyioulos@firstbhph.com> Message-ID: <46546A86.4030304@mesd.k12.or.us> Dimitri Yioulos wrote: > Thanks, Dan.

The script is set to fire off at 9:10PM via cron. So, the transfer part of the script says "if the file isn't here, wait 15 minutes, then transfer, otherwise transfer". In theory, that should give the partner enough time to get the result file to us. However, that's not fool-proof - the partner could be delayed more than 15 minutes. So, from what I've read, maybe a "do while" construct would work better. But, of course, I'm not sure how to write that either. Anyway, if I use the "if then" contruct, as I currently have in my script, it still leaves me with finding a way to verify transfer.

If you want to test if a file transfer from the box running the script worked you can just repeat it with rsync - if it's already there the operation is very cheap. If you want to test if a file is available on the other system you can run the rsync to get it, then look at your directory contents. while [ ! -e $FILENAME ] do rsync -essh othermachine:/path/$FILENAME . || sleep 900 done I usually try to write things so they do something sensible even if run at the wrong time or too often and just schedule several runs from cron instead of letting them wait, though. -- Les Mikesell les at futuresource.com From dyioulos at firstbhph.com Wed May 23 18:01:04 2007 From: dyioulos at firstbhph.com (Dimitri Yioulos) Date: Wed, 23 May 2007 14:01:04 -0400 Subject: [K12OSN] Way OT: scripting help In-Reply-To: <46547C27.3080605@futuresource.com> References: <200705221544.09931.dyioulos@firstbhph.com> <200705231230.40531.dyioulos@firstbhph.com> <46547C27.3080605@futuresource.com> Message-ID: <200705231401.05179.dyioulos@firstbhph.com> On Wednesday 23 May 2007 1:38 pm, Les Mikesell wrote: > Dimitri Yioulos wrote: > > Well actually, on second thought, I want my script to check to see if the > > file from the business partner is has been uploaded - the partner can be > > delayed, hence no file to transfer.

I want to make sure our business partner had uploaded it's file to the ftp server, then transfer it, then make sure an exact copy actually did get transfered, then delete the file on the ftp server next day. Does the construct: while [ ! -e $FILENAME ] do rsync -essh othermachine:/path/$FILENAME . || sleep 900 done wait 15 minutes if the file hasn't been uploaded to the ftp server, then do the tranfer, otherwise do the transfer (doesn't look like it does)? How would I then repeat the rsync to test that the transfer actually happened and, if not (for whatever reason), try the transfer again. Now, I hope I'm not pushing the lists good nature, but how might I log that the transfer took place successfully (doesn't matter whether it on the ftp server or the file server that it's being transferred to)?

Unless you go out of your way to avoid it, cron will send email with the output of the script to the user that set up the job. If you don't mind some uglyness, just add a -v to the rsync command and make sure email works. You could also explicitly log it with something like echo "$FILENAME arrived at $(date)" >>/path/to/logfile after the done. The ftp xferlog on the ftp server will also show when it arrived there. -- Les Mikesell lesmikesell at gmail.com From lnkemp at bolivar.k12.mo.us Wed May 23 19:03:08 2007 From: lnkemp at bolivar.k12.mo.us (Kemp, Levi) Date: Wed, 23 May 2007 14:03:08 -0500 Subject: [K12OSN] References: <4219988b0705230358l29591632r45e8c5a467d45fce@mail.gmail.com> Message-ID: I have a simple question (really it is this time).

If you are running X on the desktop where you start the ssh, you can start individual X programs and have them open their own windows back on your desktop. There are an assortment of ways to do remote GUI desktops. Vnc will work cross-platform and is set up on k12ltsp to create a new session per connection. It is also possible to install the vnc module for X that lets you access the running console session. For a straight X sessions like the thin clients get, from linux you can 'Xnest :1 -query hostname' and from windows you can run cygwin or xming X. And probably the nicest way is with freenx on the server and the free NX client that you can download from www.nomachine.com. This works nicely over low bandwidth connections and lets you suspend running sessions and reconnect to them later. -- Les Mikesell les at futuresource.com From thewhitmers at gmail.com Wed May 23 19:40:49 2007 From: thewhitmers at gmail.com (David Whitmer) Date: Wed, 23 May 2007 15:40:49 -0400 Subject: [K12OSN] In-Reply-To: References: <4219988b0705230358l29591632r45e8c5a467d45fce@mail.gmail.com> Message-ID: I use freenx with NoMachine's (www.nomachine.com) Linux or Windows clients (depending on what computer I'm connecting from).

You have to import a copy of the /etc/nxserver/client.id.dsa.key into the client's configuration setup (hit the 'key' button).

I'd like to know what you all think about it, I haven't seem much difference running 64 vs 256, and the teachers computers could really use the boost to handle XP. Go with 64+32. With only 64 you sometimes go into swap on the client when using firefox. And if swap is not enabled, they reboot. At least that's what I experienced. I was using 24 bit color on the clients. After adding more ram (128) they never rebooted. If you mix 32+64 sticks, make sure they are compatible speed wise. The 64 may be 100Mhz capable while the 32 may not. Depends if the 500Mhz cpu is a celeron or PIII. If it's a celery then you probably won't have a problem since they operate at 66Mhz FSB. If they have cdrom drives use memtest (on the 1st install cd) to test one box. It's a boot parameter. boot: memtest86 or boot: memtest You can also get it onto a floppy. -- 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 robark at gmail.com Thu May 24 01:30:22 2007 From: robark at gmail.com (Robert Arkiletian) Date: Wed, 23 May 2007 18:30:22 -0700 Subject: [K12OSN] Re: Warning: Potential yum update problem for 4.2xEL In-Reply-To: References: Message-ID: On 5/21/07, Robert Arkiletian wrote: > On 5/21/07, Robert Arkiletian wrote: > > I was not bitten by this > > > > http://kbase.redhat.com/faq/FAQ_46_10460.shtm > > > > but I know some on this list have an affected machine.

I frequent some motorcycle forums where posters link to lots and lots of high res pictures of bikes, trip pictures etc. and I often have six or more tabs open in Firefox. Add to this scenario the fact that this is a home pc and it's on for days at a time. With a Jammin 125 with 64MB of ram I would hit swap fairly often though I could reduce how often this happened by keeping an eye on client ram use and killing the X-server before ram got too low. Just shutting down Firefox was never very effective at releasing memory. I upgraded to a Term 150e with 128MB of ram a few weeks ago and have only hit swap a few times since, even then swap use was miniscule, less than 1KB. I have noticed, however, that with the same type of browsing activity the client uses more of the available memory. What before would have sucked up 60 out of the available 64M is now using say 80 out of the available 120M - it's not possible to track very precisely. This suggests that there's probably a memory sweet spot - 128M is working fine for me but 96M may also have been enough. If your teachers aren't browsing graphic intensive sites and shut down their clients every day then you should have a nice comfort margin with the 96M Robert suggested.

For several years, up to and including today, I run Pentium-166 clients with 32MB DRAM, and no, I don't have NFS swap turned on. Not once has a client died on me...and I run a whole lot of Firefox sessions and other things, simultaneously, on one client (OpenOffice.org, The GIMP, multiple Konqueror sessions, GAIM, etc.). Remember, this stuff runs on the server, not the client. Heck, I've run ancient Power Mac 5260 and Power Mac 5500 clients with 32MB DRAM, and they work just fine. So you're certainly safe with 64MB DRAM in your iPaqs If the teachers insist on running Windows XP, then you're quite safe putting those bigger sticks of DRAM in the teachers' computers. Of course, I have a better idea...tell 'em that if they go with this thin client solution, it'll speed up "their boxes" a whole lot! :-) You might get some takers. --TP Kemp, Levi wrote: > I've got a lab full of iPaqs (500MHz) that I'm pulling all the hard drives from to use for LTSP.

( you may have an option there to select either RPL or PXE). Also there may be an option in the systems bios to "use INT18" or INT19" as a pxe boot option. Without have one of these enabled the machine will NOT actually pxe boot from the onboard nic. These particular cards/chips, WILL PXE boot if the added options are correct as well. DO you ever see the lines "Intel UNDI 2.0" in the bootup process of the client going to your K12LTSP server? I m guessing not?... Hope this is clear enough ( as mud,right),,,:).

I always do it this way: find ..options... -print0 |xargs -0 command This way find writes the list of files to stdout, xargs reads them and collates into reasonable sized groups and puts them on the command line of the specified command. It's more efficient than exec'ing the command for each file and you don't have to worry about the command line size limit like you might for a wildcard expansion or command `find ...options...` The print0 and -0 xargs option specify that the names will be null terminated so embedded newlines in filenames don't confuse things. find $WORK -maxdepth 1 -mtime +$DAYS ! -name file -print0 |xargs -0 rm You can leave off the -print0 and xargs part to preview the list or redirect it to a file if you want to check it first. -- Les Mikesell les at futuresource.com From robark at gmail.com Thu May 24 19:17:00 2007 From: robark at gmail.com (Robert Arkiletian) Date: Thu, 24 May 2007 12:17:00 -0700 Subject: [K12OSN] Client Ram In-Reply-To: References: <4219988b0705230358l29591632r45e8c5a467d45fce@mail.gmail.com> <4654A1C9.2080209@paasda.org> <4654F976.1080104@cmosnetworks.com> Message-ID: On 5/24/07, Robert Arkiletian wrote: > On 5/23/07, Terrell Prude' Jr. wrote: > > I've found that you only need 32MB DRAM on your clients.

Firefox does some HEAVY caching and that eats RAM like it's free. But that aspect should only be on the server side. The TC should not see it. Hmm. Unless firefox is using the xserver to manage caching... I have firefox open (not running a TC environment) and xorg has ~98MB and firefox has ~109MB. I opened another firefox window and loaded up a bunch of new tabs with different web pages with graphics and my xorg went to 118MB and firefox went to 115MB.

About 150 users. What would be the minimum RAM I should have for my server? Also, you say that you script your Windows clients to connect to the printers during login. Is that just with a basic batch or vbscript that connects the user to a printer share? Or do you setup a local ip port for the printer on the client machine?

I'm moving all my users to printing to the queues on this server (both Windows, Mac, and Linux). You should follow the instructions for using the CUPS/MS postscript drivers so you can easily deploy to Windows clients using a login script. The CUPS/MS drivers don't need local admin access for the user to use the queues.... So no more adding special printer drivers to each client for each printer... they all use the same CUPS/MS drivers. The next step for me is to use pykota. I've got a central view of all the print jobs now so I can see if something is jammed.

Forgive me if I miss some details... Go to System, Administration, Network and see if both NICs come up in the list. If they do, see if you can enable the one that's currently disabled. You'll want one NIC to be set to DHCP, and one set to Static. The static one is the one that will connect to your thin clients, and the DHCP one will connect to the school's network. Here's where it might be confusing: the static NIC will be *serving* DHCP to the thin clients. That configuration is done elsewhere, but keep it in mind. There's a text file somewhere that specifies which NIC serves DHCP. Maybe someone else on the list can remember the name and location. If you don't have both NICs shown in the step above, go to a command line and type: lspci | grep controller The lspci command shows information for many system devices, and the | grep controller part of the command means "only show lines that contain the word controller" (which is likely to be your network cards). Post here the information you get from that command, or search google for the make/model number obtained from the lspci command, combined with the words "linux" or "module" or "help me!" or something similar. Good luck. -Rob On Thu, May 24, 2007 at 08:09:00PM -0400, Brad Thomas wrote: > Hi all.

Well, part of it comes down to tuning. Eric put together a Firefox extension that sets several options to more friendly levels. In particular: browser.cache.memory.capacity and browser.sessionhistory.max_total_viewers The defaults are variable depending on the total memory of the computer. Of course, in an LTSP environment, it's all shared, so a 4G host can't expect to have all that for one browser instance. As I understand it, the defaults have been dialed back somewhat for Firefox 2. Eric's Firefox extension dials back these values too. http://www.redhat.com/archives/k12osn/2006-May/msg00372.html -- Dan Young Multnomah ESD - Technology Services 503-257-1562 From daengbo at gmail.com Fri May 25 04:51:26 2007 From: daengbo at gmail.com (Daniel Bodanske) Date: Fri, 25 May 2007 13:51:26 +0900 Subject: [K12OSN] Client Ram In-Reply-To: <994441ae0705242009h19dde21fibcf23bc69dad69a2@mail.gmail.com> References: <4219988b0705230358l29591632r45e8c5a467d45fce@mail.gmail.com> <4654A1C9.2080209@paasda.org> <4654F976.1080104@cmosnetworks.com> <1180044075.4050.92.camel@merlin.localnetsolutions.com> <1180046189.4050.108.camel@merlin.localnetsolutions.com> <20070525010423.GB6209@clubber.owens.net> <994441ae0705242009h19dde21fibcf23bc69dad69a2@mail.gmail.com> Message-ID: So Firefox stores pixmaps uncompressed in the X server cache. Unbelievable. Is it Firefox or Gecko? Does Seamonkey suffer the same limitation. Could you move to Epiphany? Wow. I began to get scared a few years ago when so many new desktop applications started to get written for Linux. So many of them wouldn't work over the network. I got worried that LTSP might become non-viable some day when all the standard apps needed local resources. Once Freedesktop.org was started and picked up momentum with Jim as one of the founding members, I calmed down, but I guess I shouldn't have. Firefox seems to follow it's own rules all the time, anyway.

Same for my boxes with ATI 3D Rage Pro video boards (8MB video RAM). I also successfully use S3 Trio64 boards with 2MB video RAM at 1024x768x16bpp. Most of my thin clients have 32MB main memory, and most are Pentium-166's, though a few do have 64MB. I've seen no difference. Now, what *does* make a difference in performance is the video board. Oh My God, does it make a difference! The client with the Millenium G400 can do anything--MPlayer video, TuxRacer, you name it without slowing down. The ATI 3D Rage Pro isn't quite fast enough to keep up with 640x480 MPlayer video (you need to use the -framedrop switch), though it'll do 320x240 just fine. The S3 Trio64 is--barely--good enough for TuxType, but forget about watching videos; that said, it's just fine for Mozilla/Firefox/OpenOffice.org-type stuff. I've done all this without ever--once--using NFSSwap, and except for the occasional hardware failure (e. g. DRAM or NIC goes bad), my clients don't crash. --TP _______________________________ Do you GNU!?

The Xserver caches pixmaps and fonts. No big deal. It's part of the design of the X Window System. The problem is, with tabs, the browser can actually be viewing more than one page at a time, which means there can be alot more pixmaps sent from the browser to the Xserver. The Xserver just happily caches them. A flaw in this design is the fact that when the thin client gets low on memory, the Xserver has no mechanism to deal with it. It can't throw away pixmaps from the cache, because it has no way of telling the client application that it no longer has the image cached, so there's no way for firefox to re-send the pixmap when the user comes back to that page. So, sadly, the Xserver runs out of memory, and bad things happen. I've brought this up to the X.org developers and everybody agrees that it's a big problem, but unfortunately, there's not an easy fix. It's not just firefox that is involved here. Any graphical application will send images and fonts to the Xserver, and expect those things to still be in the Xserver later on. I suppose Firefox could be modified to never expect those things to be cached, which means it would have to send the images and fonts each time you switch from one tab to another, or scroll the page up and down. Imagine the screams you'd be hearing as the performance goes down the tubes, and the network traffic goes through the roof. We tried fixing this a few years ago in LTSP by placing a limit on how much ram the Xserver could allocate. This managed to keep the Xserver from crashing, but then the client application would crash because it didn't expect the Xserver to fail to allocate the memory for it. If the client is the browser, the browser would crash, which is easily recoverable. But, what if the client application is something more important, like the window manager? It's a tough problem, and I wish I had the magic fix for it.

Err, mad props to Moz, X.org, and LTSP developers. ;-) With the browser.sessionhistory.max_total_viewers setting, Firefox is also somewhat aggressively storing the rendered version of recently viewed pages, tuned by total RAM of the host. Effectively, it's trading RAM for CPU time. It's not just pixmaps for tabs and browser windows. http://kb.mozillazine.org/Browser.sessionhistory.max_total_viewers -- Dan Young Multnomah ESD - Technology Services 503-257-1562 From brcisna at eazylivin.net Fri May 25 15:28:48 2007 From: brcisna at eazylivin.net (Barry Cisna) Date: Fri, 25 May 2007 10:28:48 -0500 (CDT) Subject: [K12OSN] sudden appearance of grey X Message-ID: <41751.216.24.126.67.1180106928.squirrel@www.eazylivin.net> Julius, I'm not sure if you can do this, if you are 1600 miles away from server,and you can not vnc to it. try and install Webmin so you can have another alternative to accessing your server. Next in Nautilus, drill down to: /etc/hosts.conf file. You should have at the top> 127.0.0.1 localhost.localdomain localhost ..listed If this entry is not showing add it,,then reboot your server. If this entry is missing things will work fine until the server is rebooted. Something similar happened like this on one of our servers a long time ago, and this was the fix. Don't know how the localhost/hostname disappeared,but never had a prob after this. Also, I presume you can ssh to this server remotely fine? Let us know your progress.

Errors with No DHCP > reply so I gave up and booted from floppy. Problem solved :) > Ok looking over my original email I realized I forgot one teeny-weeny fact, I piggybacking on an existing network with another box (IPCop). I have an existing network of about 200 PC's running through IPCop (static IP's). Out of those 200 PC's I needed to convert 16 PC's over to k12ltsp (using the same physical network). I've read others were doing it so I figured it would work too as long as I turned off DHCP services on the IPCop box. IPCop: DHCP services: OFF - network: 192.168.0.0/24 K12ltsp: DHCP Services: ON - network: 192,168.1.0/24. Both on the same physical network. For the most part the setup is working but here is what I have observed: I have a few PC's that have the built-in nic as described before. The one I had trouble with will not boot from the NIC using the BIOS configuration. The other PC's will boot from the NIC via BIOS configurations. So, I'm thinking that it was just a single PC issue. The rest of the PC's boot from the floppy because they have no buil-in nic and we don't have the bootproms installed. Booting from the floppy I get several (about 4) "No IP found" errors then it kicks in and loads up. I thought that it might be from heavy network load but I looked at it this morning under light traffic and still got the same "NO IP Found" errors. It looks like I get 3-5 of those errors then it kicks in and boots up. I really don't see it as a major problem right now. Even under heavy network load the k12 clients seem to work fine. Well, at least they are able to boot up and people can log on and surf the web. I'll have to wait and see later on when the k12 pc's get more useage. Anyone see anything that could account for the "NO IP Found" errors? I have a Netgear gigabit and CISCO 3550 switch between the the k12 server and the PC's. I wonder if they could be causing the errors. Oh well, sorry for the omission of some vital information. Just an oversite.

I could use a little clarification. According to this, you'd likely need 256MB or more in your thin client for just regular ol' Web surfing, or writing OpenOffice.org documents, or viewing photos of your kids--anything involving these images getting turned into pixmaps by *any* X11 application, and 512MB in the client would not be unreasonable at all. But now we're getting into thick-client territory; Dell's new Ubuntu PC's come with 512MB DRAM. I know, from experience on my thick clients, that X11 can suck up over 400MB until I start shutting apps down (Firefox is one of those apps; Evolution is another). However, I also know, from experience, that my clients with 32MB and 64MB do not die when I use Firefox, etc. According to the below, X11 should indeed be dying on them left and right. I'm using K12LTSP 4.2EL. Could there be something else that we're just missing here? --TP _______________________________ Do you GNU!? Microsoft Free since 2003 --the ultimate antivirus protection!

Message-ID: <2be970b50705251037x2e15118ekc3bf2237e64145c9@mail.gmail.com> Hello all, I hope this is an easy one. I am using samba and winbind to allow Windows users to login to my LTSP box. Samba will automagically create a home directory for them if they don't already have one. The problem is a user who logs in as 'user' or 'USER' or 'UsEr' all get a home created for them the first time they log in with whatever permutation of their username there fingers fall on. Doing id 'user', 'USER' and 'UsEr' shows me that each of these logins share the same UID. To combat this, I want to force all user directories to be created lowercase despite whatever the students type. Since I use Gnome I tried adding this line to /etc/gdm/PostLogin/Default: u=`echo $USER | tr A-Z a-z` but it didn't help. I think that samba uses this line in /etc/pam.d/common-session to create the home directory on the fly: session required pam_mkhomedir.so umask=0022 skel=/etc/skel but it doesn't look like I can pass arbritary options (like 'tr A-Z a-z` ) Am I being dumb? Is there an easy switch in smb.conf ? I hope someone can help! Thanks, John Here's my smb.conf: [global] security = ads realm = my.domain.ORG password server = 10.114.5.50 workgroup = STUDENTS # winbind separator = + idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes template homedir = /home/%D/%U default case = lower #template homedir = /home/McM/%U template shell = /bin/bash client use spnego = yes client ntlmv2 auth = yes encrypt passwords = true winbind use default domain = yes restrict anonymous = 2 From ray at mission.lib.tx.us Fri May 25 18:20:38 2007 From: ray at mission.lib.tx.us (Ray Garza) Date: Fri, 25 May 2007 13:20:38 -0500 Subject: [K12OSN] BUILT-IN NIC - solved (sort of) In-Reply-To: <465718B9.4070300@cmosnetworks.com> References: <200705241129.26812.ray@mission.lib.tx.us> <200705251153.06391.ray@mission.lib.tx.us> <465718B9.4070300@cmosnetworks.com> Message-ID: <200705251320.38615.ray@mission.lib.tx.us> On Friday 25 May 2007 12:11:21 pm Terrell Prud?

Well, I'm probably going to end up with 128 in all of them anyways. It occurred to me that if one of the XP boxes need a stick of 64 in it then it probably needed lot more than just 64. It seems like they had to make a fair trade in the use of resources with the xserver. I'd rather have to increase the ram in a client by 32mb then to increase network bandwith and push it back to the server. Thanks for the input.

The Xserver caches pixmaps and fonts. No big deal. It's part of the design of the X Window System. The problem is, with tabs, the browser can actually be viewing more than one page at a time, which means there can be alot more pixmaps sent from the browser to the Xserver. The Xserver just happily caches them. A flaw in this design is the fact that when the thin client gets low on memory, the Xserver has no mechanism to deal with it. It can't throw away pixmaps from the cache, because it has no way of telling the client application that it no longer has the image cached, so there's no way for firefox to re-send the pixmap when the user comes back to that page. So, sadly, the Xserver runs out of memory, and bad things happen. I've brought this up to the X.org developers and everybody agrees that it's a big problem, but unfortunately, there's not an easy fix. It's not just firefox that is involved here. Any graphical application will send images and fonts to the Xserver, and expect those things to still be in the Xserver later on. I suppose Firefox could be modified to never expect those things to be cached, which means it would have to send the images and fonts each time you switch from one tab to another, or scroll the page up and down. Imagine the screams you'd be hearing as the performance goes down the tubes, and the network traffic goes through the roof. We tried fixing this a few years ago in LTSP by placing a limit on how much ram the Xserver could allocate. This managed to keep the Xserver from crashing, but then the client application would crash because it didn't expect the Xserver to fail to allocate the memory for it. If the client is the browser, the browser would crash, which is easily recoverable. But, what if the client application is something more important, like the window manager? It's a tough problem, and I wish I had the magic fix for it.

Message-ID: <46584311.3070807@earthlink.net> Are we the only school that has this problem, because we allow our kids to have complete access to computers all over the building all the time? I happened to substitute for the computer lab teacher last week just two days of the week. I know of at least three reams of unclaimed printing in the computer lab (we have two of the network printers in there) just last week alone! Kids and teachers print things -- they don't want to look through the pile, or to wait for their job to print, or really even know where their job went because they didn't pay any attention, and so they print it again... and again... Our school doesn't have grades per se, they use portfolios to demonstrate kids' learning. This is high season for completing portfolio work and every year at this time, I am reminded of this print problem of trying to control printing. http://www.pykota.com/ Have you ever used this software? Or know of some kind of control software? I looked at this Pykota website a few years ago, but we were resolving so many other issues that I never looked at it again. Now that it is on my mind again, I need to look at it a little more. Uncontrolled printing may be a problem whose time has come to solve. I'd love a software that popped up a message to the user that said "I'm sorry, but you sent this job to the XYZ printer three minutes ago, are you sure you want to print it again?" or "I'm sorry, but you sent this job to the XYZ printer three minutes ago, there are four jobs printing to that printer ahead of your job, it will be approximately three minutes before your job will finish, would you like to send this job to an alternate printer, or wait for this job to print at XYX printer?" Or, "I'm sorry but you have met your print quota for the day, you must ask a printer administrator to give you a Exception Key key in order to print any more pages today." Maybe that's too extreme, however, what I saw last week was pretty wild with paper all over the floor and on the tables around the printers, stacks of unclaimed print jobs on the printer, the network printer in the hallway upstairs was the same, and sometimes worse.

I wish I knew about this software when I started. It would have saved me several days of work. Make sure you're using a supported distro such Fedora Core 5 or Ubuntu. For login scripts, kixtart is very capable. I use kixtart to map network drives, update registry entries, setup folder redirection, install software, and to install and configure network printers. It's a beautiful thing! To get the functionality of the Windows Remote Installation Service (RIS), I consulted unattended.sourceforge.net. To lockdown and standardize user desktops, you can implement mandatory user (roaming) profiles. You can find instructions and examples on this topic by search Google.

It sounds like you might be in runlevel 3 instead of 5 on the server. You might find something in the servers /var/log/Xorg.0.log if it is trying to start and failing there too. The fact that vnc won't start a session makes me think this is something on the server side but I'm not sure how to tell remotely if it is at the basic X level or in the window manager startup. You might also look through /var/log/messages and the output of dmesg on the server to see if you are getting disk errors - it could be failing to load some needed file due to a hardware problem. Time to work a spare server into the budget for next year... This stuff doesn't fail often but when it does the best quick fix is another one that already works. -- Les Mikesell lesmikesell at gmail.com From rowens at ptd.net Sat May 26 17:56:52 2007 From: rowens at ptd.net (Rob Owens) Date: Sat, 26 May 2007 13:56:52 -0400 Subject: [K12OSN] HP 1012 host based printer Message-ID: <20070526175652.GA10769@clubber.owens.net> Just sharing a success story.... One of my P3 desktop-turned-thin-client machines had an HP 1012 printer attached to it when it was running a local Windows OS. When I turned it into a thin client, I had trouble because this printer is "host based", which means it needs to be connected directly to a Windows machine and cannot be attached to a print server. It's like the printer equivalent of a winmodem. No windows machines could access it as a Jet Direct printer. Anyway, there is a Linux driver for this printer, and Linux was able to print to this printer when it was attached to a thin client. Installing the windows driver on the windows machines, however, failed when it realized that the printer was on a "print server" (the thin client) and not attached to a windows box. So I shared the printer from the K12LTSP server, then I set up an "internet printer" in windows with this URL: http://myservername:631/printers/myprintername It works! Imagine, a Linux printer driver that's *better* than the Windows driver.... -Rob From julius at turtle.com Sat May 26 18:20:34 2007 From: julius at turtle.com (Julius Szelagiewicz) Date: Sat, 26 May 2007 14:20:34 -0400 (EDT) Subject: [K12OSN] sudden appearance of grey X In-Reply-To: <4658490C.10408@McQuil.com> Message-ID: On Sat, 26 May 2007, Jim McQuillan wrote: > Julius, > > This is the point where I bring out the big guns. > > tcpdump -i eth0 port 177 > > Then, have someone turn on a thin client, and watch the traffic. > > You should see the request from the client, and then a reply from the > server.

The countermen went fishing with dissatisfied customers, nobody in the building, just a message - "make sure it all works Tuesday" The starange thing is that the VNC client gets a grey screen too. I'm beginning to think I might be getting first hardware failure in 5 years on a Gateway server.

I read somewhere that network printers that you have to walk a long distance to reach are a big waste of efficiency. An alternative is to have more printers located close to those who are printing. Search the archives and you will find scripts that direct the printing to the nearest printer. It also "divide and conquer"s the task allowing teacher's to supervise the kids in there immediate vicinity. Much easier than trying to manage print jobs for a whole department or school. Hope this is helpful. Look forward to hearing other suggestions.

In-Reply-To: References: Message-ID: <1180212707.5604.19.camel@200-8143-202-01> The problem with this is that a *lot* of print jobs in a school are 1-2 pages, so you end up increasing the amount of paper used by a great deal just to deal with the deviants. I like the idea of giving students a fixed number of pages at the beginning of a semester (perhaps based on which classes they're taking) and charging them a per page fee, based on actual costs of paper/toner/etc., if they go over.

This was not a problem before.i I've usually had trouble not having the gui console if I wanted XDMCP and vnc to start sessions. And it might be easier to find logged error messages if the console session is failing the same way. -- Les Mikesell lesmikesell at gmail.com From jam at mcquil.com Sat May 26 19:36:15 2007 From: jam at mcquil.com (Jim McQuillan) Date: Sat, 26 May 2007 15:36:15 -0400 Subject: [K12OSN] Client Ram In-Reply-To: <20070526132654.GA9797@clubber.owens.net> References: <4654F976.1080104@cmosnetworks.com> <1180044075.4050.92.camel@merlin.localnetsolutions.com> <1180046189.4050.108.camel@merlin.localnetsolutions.com> <20070525010423.GB6209@clubber.owens.net> <994441ae0705242009h19dde21fibcf23bc69dad69a2@mail.gmail.com> <4656D15B.4030101@McQuil.com> <20070526132654.GA9797@clubber.owens.net> Message-ID: <46588C2F.1020908@McQuil.com> Rob Owens wrote: > Couldn't Firefox and/or the Xserver be rewritten to behave like this: > > 1) use only a certain amount of memory for cache > 2) when that memory is full, delete the oldest cache > 3) when a request comes in for a cached image, deliver it if it's > available, but... > 4) if the requested image has been deleted from cache, then re-request the > image from its original source (the internet) The Xserver doesn't know anything about the internet. It received the image from the client application (firefox). If the Xserver deletes the image, due to memory being full, it would need to tell firefox to resend it. Unfortunately, there's no mechanism for that in the X11 protocol. Sure it could be added, but you'd have to consider whether that breaks anything in the protocol. Keeping in mind that there's an awful lot of programs out there that depend on the current protocol.

Does the terminals come up to a command prompt login,OR do you get a " blue background/desktop" with no place/window to type in your username/password? >From what I understand you are getting strictly the dreaded grey X,and nothing different? In your lts.conf file do; SCREEN_01 = startx SCREEN_02 = shell * if you have an rdesktop line enabled here,comment it out* (#) reboot the client box, then do your CTL-ALT-F1 & CTL-ALT-F2 ,and see if this gives you a different "look" to your login. If nothing changes toggling your window sessions,,then something is hosed the Xdmcp,,somehow,somewere. By doing the CTL-ALT-F2 you should at least get changed to the command prompt login. I know this does not really explain why vnc does not give you a login placeholder ,either. Another thing to try is the good old ' hostname' in a terminal. Make sure you are actually seeing the FQDN of this server At this point it almost sounds like it may be time to reformat. Ive run into the same thing in the past,and found in the end I would have saved lots of time, reformatting, I know though you don't actually figure out what caused the server to do this:(.

I've got an issue that I can't seem to narrow down though, Yum doesn't work, actually anytime I try to install an RPM I get an error because it cannot resolve dependencies stating there may be no connection. This is odd because I do have a internet connection working and I even disabled iptables and SELinux just to make sure. Any thoughts on what else I might check? I'm assuming if I wait a few more days for the final release and install fresh it will go away but I would rather keep what I have going. The install from the Live CD was great by the way. I played a game of Sudoku while it installed in the background, really quick I might add. I forgot to mention to my wife I'd switched it over, I didn't use grub, and had it log in automatically. Found her surfing the internet and playing Mahjongg this morning, obviously it didn't matter to her at all, and she had never even seen Linux yet. Thanks for any ideas.

Certainly firefox could go get the image again, or cache it for itself. the problem is, it has no way of knowing the Xserver has thrown it away. Jim.

I copied over the simplest working xorg.conf file I could find, changed the video driver to fit and lo and behold - the console X comes up and VNC works. I don't know if the terminals will come up, but I have high hopes. I can't for the life of me figure out what the console setup has to do with VNC, but obviously there is a direct connect. I can't figure out why the VNC -stopped- working without any changes in system software.

Windows users and LTSP users network share should be accessable either as \home while on LTSP or as a network share when using WindowsXP. Hardware 35 thin clients clients 1 LTSP server (2 duel core opteron 8100, 8 Gigs of ram, Edubuntu 7.04) 1 "backend" file server doing NFS, SAMBA, LDAP and Webdav, 3 Ghz workstation with 4Gb ram (Centos or Ubuntu LTS 6.06) 1 Dedicated Gig E switch Software/networking: 1. The LTSP server will authenticates clients via the LDAP backend server. Users home directories will be stored on the backend server. 2. The LDAP backend server is joined to our Windows AD Domain, via winbind and linux user accounts are automagically created via SAMBA which stores account info in LDAP per http://us4.samba.org/samba/docs/man/Samba-HOWTO-Collection/idmapper.html#id369912 My question are: 1) What am I missing, forgetting etc? 2) Is my authentication scheme nuts? I can't dump Active Directory, but is there a better way to do this? 2) Do I need a "real" server doing RAID 5 or whatever for the LDAP Backend 3) Am I REALLY off base with my proposed setup? Many thanks for any and all ideas!

The problem on a multi user machine is that every user wants the disk head to be in a different place at the same time so seek time is often more important than transfer rates. Consider what happens when everyone is using a browser and every page and image each user loads is being cached in their home directories. Scsi disks/controllers can typically take a bunch of commands at once and queue them up while IDE and most SATA's can only do one comand at a time, waiting for CPU intervention at each step. -- Les Mikesell les at futuresource.com From steven at simplycircus.com Wed May 30 04:17:31 2007 From: steven at simplycircus.com (Steven Santos) Date: Wed, 30 May 2007 00:17:31 -0400 Subject: [K12OSN] [OT] Downloading GPS data In-Reply-To: <774593a20705291850o59ca23b8x2b5275adc914cc96@mail.gmail.com> Message-ID: OK, lets see. Many moons ago I used GP50 data loggers to record seismic pressure readings. The two older units recorded readings from the pressure sensor via a serial port, while the newer units had the GP50 built into the housing of the sensor unit. Poking around an archive CD from 1996, I have a file called pos-gp50.hw2 (ahh, home word 2...) Here are the contents of that file: {begin} Downloading from the data loggers 1. Using the blue cable on FRED, connect the data logging unit (serial port 2) 2. Fire up Terminate, and select "GP 50" from the dialing menu 3. Once connected, you will see a flow of current data Press crtl-b repeatedly until you get a ">" or ":" prompt 4. Turn screen capture on 5. enter "type pdata" 6. When data dump ends, turn screen capture off 7. delete the extra lines from the capture file 8. save to a floppy disk and give to Toni or Laura On the red units pressing tab at the prompt will give you a menu.

I just checked the K12LTSPv6 box I have at home and it works just fine. Note that if you run the openoffice-ms-format-defaults.sh script more than once, it will generate the *.rej files (it cannot patch an already patched file). The *.rej files themselves are not necessarily an indicator of a problem.

Runlevel 5 tries to start the console session and gdm and apparently stops if the console doesn't work. Somewhere I've seen the config change needed to not bother with the console session but I've forgotten it. After gdm is working I think you can modify xorg.conf and start/restart the console session if you want to put the broken copy back and see if you can find what it is complaining about in the log. It could be something like needing to auto-detect the monitor capabilities for the screen resolution you have set but the monitor is unplugged or powered down. -- Les Mikesell les at futuresource.com From lists.john at gmail.com Wed May 30 15:37:29 2007 From: lists.john at gmail.com (john ) Date: Wed, 30 May 2007 08:37:29 -0700 Subject: [K12OSN] Sanity check needed before rollout In-Reply-To: <200705300705.21188.MrJohnLucas@gmail.com> References: <2be970b50705291416t2f17dd72uf76bb4eb1181cb67@mail.gmail.com> <465CE170.5030409@futuresource.com> <200705300705.21188.MrJohnLucas@gmail.com> Message-ID: <2be970b50705300837g5a7423cdp595aeb0d3056431a@mail.gmail.com> Thanks Les and John for that clarification.

However, if cost constraints are an issue (and I've seen plenty of situations in which that's the case), I've actually used PATA for a 25-student lab. Yes, EIDE. One disk. And nobody complained. Granted, it was an update from the Windows 98 that they were using, on Dell Optiplex GX1's, so the speed increase by going with K12LTSP was heartily welcomed, but if things were "slow", I would've heard about it (it's a Microsoft shop). Therefore, I'd suspect that a hardware RAID using SATA would be just fine for 35 students. --TP _______________________________ Do you GNU!?

What about a "middle course" of a SAS controller with SATA drives? It seems that would be an improvement over Plain Old SATA for not too much extra cash. Still not as good or as expensive as SCSI. Is that correct? For instance, what do you think of this controller with four SATA drives in a RAID 5 or RAID 10 configuration? Controller and four 250GB drives (750GB as RAID 5, 500GB as RAID 10) would cost in the ballpark of $450, which seems pretty attractive. http://www.newegg.com/Product/Product.aspx?Item=N82E16816118086 The difference in drive price between SATA and ATA100 or ATA133 seems pretty negligible so it's really just the cost of the controller. -- Henry From jim.c.christiansen at gmail.com Wed May 30 16:19:13 2007 From: jim.c.christiansen at gmail.com (Jim Christiansen) Date: Wed, 30 May 2007 09:19:13 -0700 Subject: [K12OSN] RE: Sanity check needed before rollout Message-ID: <8b88203f0705300919t57e81745g44d8ab32fed1f43f@mail.gmail.com> To add to what David Trask had to say..

I'm about to build a SATA array using an LSI Logic controller. Matter of fact, I have a preference for LSI Logic controllers, due to the fact that they publish their chip programming specs without NDA. We've got a few Sun v20z and v40z boxes that use the MegaRAID SCSI cards, and they work very nicely. _______________________________ Do you GNU!?

So, I trust the heads from this list to give me some advice on getting library catalogue software installed and running. I'm setting up my childrens school with a Windows 2003 Enterprise server/network. It will have about 25 desktops and 15 laptops (mobile wireless lab), running XP Pro. I have help from a software engineer to get the domain and permissions set up. I talked the technology and library committee out of spending thousands on Destiny for the library, and I have been fiddling around with Koha and Openbiblio. My original thought was to get one of these programs running on the Server 2003 box. I don't suppose it matters if it is located on the server, or on a stand-alone box. My problem is that I have not been able to get either Koha or Openbiblio fully functional on a Windows platform. With Koha, I have it installed, and it appears to be working fine; except that I cannot get z39.50 working, which is crucial. If I cannot get this to work, so we can easily download bibliographic information with a barcode scanner, then I'm up a creek. So, I'm wondering if I could get the catalogue software on a stand-alone linux box. As long as it has a GUI, it shouldn't be a problem for the librarian. So, my question is: Is there a distribution that has either Koha or Openbiblio set up out of the box? I'm not much of a command line guy (teacher, not a penguin). The more simple GUI to get it going, the better. I've not had much luck with instructions I've found on the internet, which is why I'm turning to the list. Someone Help!!!!

Message-ID: <2be970b50705311230v7137bda9l6c0c4a50089af94b@mail.gmail.com> Hello all, I am trying to get THE definitive take on a question I have regarding the necessity of using a fast disk array for LTSP. I touched on this in a previous email and got some good advice. I want to probe a little bit more if you don't mind. I hope I don't sound too dumb as I ask these questions: I have read Jim's piece on disk setup's here: http://wiki.ltsp.org/twiki/bin/view/Ltsp/ServerSizing#Hard_disks I brought this question up on the list in a slightly different form and got responses that were helpful: Les pointed out: "The problem on a multi user machine is that every user wants the disk head to be in a different place at the same time so seek time is often more important than transfer rates. Consider what happens when everyone is using a browser and every page and image each user loads is being cached in their home directories. Scsi disks/controllers can typically take a bunch of commands at once and queue them up while IDE and most SATA's can only do one comand at a time, waiting for CPU intervention at each step." And John said: "The behavior ("Scsi disks/controllers can typically take a bunch of commands at once and queue them up..."), is known as "elevator seeking" and is a huge advantage of SCSI over SATA." However a unix guru I work with responded to me: "But--at least in all the UNIXen I ever worked on--you can and do implement this in software. And not in hardware." To prove his point we did the following: We tested our installation in a lab with 30 thin clients attached to a single commodity workstation running ubuntu/ltsp4.2 with 2G ram, 3Ghz processor. We used vmstat to monitor CPU,memory usage and disk i/o. We found that disk I/O was relatively light after application startup and that slow downs began to happen as processes queued up behind the CPU waiting for their time slice to be handled. In short client speed fell off as the CPU got busier, and not because of busy disks. Were we looking at this in the wrong way? Was there a better way to determine Disk IO? I am leaning toward getting a fast array, but I would like to understand this better before I do.

Hello all, I am trying to get THE definitive take on a question I have regarding the necessity of using a fast disk array for LTSP. I touched on this in a previous email and got some good advice. I want to probe a little bit more if you don't mind. I hope I don't sound too dumb as I ask these questions: I have read Jim's piece on disk setup's here: http://wiki.ltsp.org/twiki/bin/view/Ltsp/ServerSizing#Hard_disks I brought this question up on the list in a slightly different form and got responses that were helpful: Les pointed out: "The problem on a multi user machine is that every user wants the disk head to be in a different place at the same time so seek time is often more important than transfer rates. Consider what happens when everyone is using a browser and every page and image each user loads is being cached in their home directories. Scsi disks/controllers can typically take a bunch of commands at once and queue them up while IDE and most SATA's can only do one comand at a time, waiting for CPU intervention at each step." And John said: "The behavior ("Scsi disks/controllers can typically take a bunch of commands at once and queue them up..."), is known as "elevator seeking" and is a huge advantage of SCSI over SATA." However a unix guru I work with responded to me: "But--at least in all the UNIXen I ever worked on--you can and do implement this in software. And not in hardware." To prove his point we did the following: We tested our installation in a lab with 30 thin clients attached to a single commodity workstation running ubuntu/ltsp4.2 with 2G ram, 3Ghz processor. We used vmstat to monitor CPU,memory usage and disk i/o. We found that disk I/O was relatively light after application startup and that slow downs began to happen as processes queued up behind the CPU waiting for their time slice to be handled. In short client speed fell off as the CPU got busier, and not because of busy disks. Were we looking at this in the wrong way? Was there a better way to determine Disk IO? I am leaning toward getting a fast array, but I would like to understand this better before I do.

And not in hardware." I don't think the current Linux implementations do a very good job of re-ordering seeks if it even tries at all. However, it does buffer to whatever extent that it can. Writes are always buffered unless there is no RAM left (and the flush to disk might be done in sector order so you would get some re-ordering there). Reads are held in the disk buffer until the space is needed for something else, so additional RAM can make a huge difference when multiple users frequently access the same things. The difference with SCSI is that the controller can re-order queued commands after the CPU sends them so a read request for something between two pending requests might be serviced as the head goes past its location. My recommendation is to max out the RAM you can put in the box first, then if you have money left go for the faster drive set. > To prove his point we did the following: > > We tested our installation in a lab with 30 thin clients attached to a > single commodity workstation running ubuntu/ltsp4.2 with 2G ram, 3Ghz > processor.

Iostat will show i/o per-device but neither will give a good measure of the time that seeks are wasting which is the real problem. If you had a matching load on a SCSI and IDE machine you might be also able to see a difference in the system interrupts and context switch columns of vmstat as the CPU has to do a lot more to drive an IDE controller (like issue a seek and wait for completion before starting the data transfer) and each of those operations involves an interrupt and context switch. -- Les Mikesell lesmikesell at gmail.com From mrjohnlucas at gmail.com Thu May 31 20:37:37 2007 From: mrjohnlucas at gmail.com (John Lucas) Date: Thu, 31 May 2007 16:37:37 -0400 Subject: [K12OSN] Are fast disks really that important and why?

With SCSI more of the "intelligence" is in the drives than with SATA. So for each I/O operation, less CPU is taken up with the SCSI system vs. the SATA system. The availability of higher platter speeds with SCSI (15K rpm) vs. SATA (7200 rpm with smaller drives available at 10K rpm) has the advantage of higher sustained transfer rates (for sequential reads, like application loading) as well as being "quicker" to place any given sector under the read head (random seeks). These are marginal considerations (for me). If my budget accomodates SCSI, I would prefer it over SATA. As part of a server purchase amortized over 4 - 5 years (typically), the cost difference isn't that great. Only when every dollar is being scrutinized by some bean counter would I consider cutting this particular corner. Having said that, either system works acceptably and I wouldn't spend too many restless nights worrying if you got the absolute fastest solution. Reliability of the hardware and the worth of the warrantee (vendor) are more important. -- "History doesn't repeat itself; at best it rhymes." - Mark Twain | John Lucas MrJohnLucas at gmail.com | | St. Thomas, VI 00802 http://mrjohnlucas.googlepages.com/ | | 18.3?N, 65?W AST (UTC-4) | From lists.john at gmail.com Thu May 31 21:15:44 2007 From: lists.john at gmail.com (john ) Date: Thu, 31 May 2007 14:15:44 -0700 Subject: [K12OSN] Are fast disks really that important and why?
