I simply reformatted the thumb drive as ext3, and everything worked great. But I'd expect Jim's downloads to die at 4GB, not 474MB. Even with the plethora of problems that MS Windows has, that's still very odd. I've never seen downloads consistently die at that number. Could it be that MS Windows boxes are attempting to download the file in pieces, i. e. a "0.5GB" part, followed by the rest of the 4GB? Sort of like a built-in (but apparently broken) UNIX "split" functionality? --TP _______________________________ Do you GNU ?

I haven't done it yet, but I plan to. Yesterday I had my server "heavy" day. Things worked at normal speeds. I am not sure what happened last week. However the server was extremely slow. I used the System Monitor and watched it all day. Yesterday, when things were slow it was either: a lot of network usage or CPU usage, but not both. In the morning the students were on Window boxes using Flash and Samba. I think some of them were working directly off of the server: saving/executing. I think that might have slowed things down. I asked them to copy the file onto their desktops and work from there and then save it to their folders. It seemed to work a bit better. During the afternoon (they were on a Linux box), there was no noticable lag. I also asked the students to try to use Opera instead of Firefox. They complained a bit but it was nice to see the CPU numbers go down. I'm hoping that it'll stay this way for at least the rest of the week. =] Thanks for all your help! _________________________________________________________________ -------------- next part -------------- An HTML attachment was scrubbed...

If you've already got a lot of disk I/O going, that will certainly slow things down. In your situation, I'd have a physically separate, dedicated file server with hardware SATA RAID (level 5 or 10) and at least six spindles (hard disk drives); the more spindles here, the better. Any time I do any heavy disk I/O on my K12LTSP server here at home, it slows down the server. Of course, my server has only a SATA RAID 1. About five years ago, I had installed a K12LTSP server into a 25-station lab, using Pentium II's as EtherBooting thin clients. It was a dual AMD Athlon MP, used twin 80GB EIDE disk drives, and had 4GB DRAM. It was also one of the school's major file servers. The server was not slow...but only because the DRAM caching was saving my butt (the K12LTSP 2.12 of that day used way less DRAM). Today, I would never try that. > > During the afternoon (they were on a Linux box), there was no > noticable lag. I also asked the students to try to use Opera instead > of Firefox.

It takes wonderful advantage of shared libraries (thus lower DRAM usage) and also will find/use the Firefox plugins (Flash, etc.).

I moved to a different state (NH), and my association with the school where I installed L12LTSP necessarily ended. Last year my new church opened a new school, and this year, I have deployed K12LTSP again. It's good to be back. Last year we received six PC's as a donation, and they came with Win2K installed on them. We didn't have Internet access then, and I was not ready to fight the good fight yet. I did install OpenOffice on all the machines though, and that was pretty much all they wanted. This year they started asking for more, and for everything they said they wanted, I remembered having it for free at my previous school. So I proposed piloting k12ltsp and got a green light. I commandeered the PC we have in the AV room as the ltsp server. It's a fairly decent machine (about double the speed, memory, and HD of the server I had at the previous school). During setup, one of the six Win2K machines (which are my clients now) gave up the ghost. It is an ex-PC now. So I'm down to five clients. The first day went pretty well. The kids were very excited, and had a blast. OOo looks just the same as last year (no accident there). I have had a chance to speak to the teacher only briefly, but her impression was also very positive. So it looks like I'll get a green light. Since the pilot is going well so far, I decided to start looking for a permanent ltsp server so we don't have to rely on the AV PC. I found a place to buy some very impressive looking refurbished blade servers for next to nothing, and I'd like a little advice: http://www.geeks.com/products_sc.asp?cat=821 The one I have my eye on is an IBM 1U blade with two 2.4GHz Opterons, 4G RAM, and a single 73G Ultra320 SCSI drive: http://www.geeks.com/details.asp?invtid=E326-R&cat=SYS I could go with a bigger drive if I went with a no-name blade, and it would be SATA instead of SCSI. SATA is nice because I can get more capacity cheap, but SCSI just seems so much better. And with only 7 students in our whole school, I'm thinking 73G will last a long time. So what would you do? Go for a no-name with more HD capacity and a cheap upgrade route, or go with IBM+SCSI knowing that adding more storage later is going to cost some major bux? I'm also looking at one of these to replace my smoked client: http://www.geeks.com/details.asp?invtid=SAMBA845V-24-4-R&cat=SYS Has anyone dealt with geeks.com before?

Monarch used to make a good server before they finally bit the economic dust. Just about all of the no-names are going to use standard components--Tyan/Supermicro motherboards, Maxtor/WesternDigital/Seagate hard disks, and so on. The "tier 1" manufacturers roll their own mobos, and thus their boxes can be a royal PITA to upgrade down the road. Monarch boxes, for example, use Tyan mobos, as do those from Penguin Computing. Don't worry so much about CPU clock speed. The bigger deal is DRAM. For your projected load, any CPU's that are 1.6GHz or faster are going to do a mighty fine job.

I've found SATA to be quite a good compromise between bucks/GB and performance, so SATA would be my recommendation.

I just tried to repair a broken Dell 5150 desktop. The motherboard went bad. I was about to replace it when I realized that the expansion slots are on the opposite side of the board than every other board I've seen. So I had to buy a Dell board or nothing. All they had was a refurbished unit for $300. It takes a P4 chip and has 2 SATA ports. It's obviously not worth $300, so the computer is junk now. > Don't worry so much about CPU clock speed.

The kids then try to re-open Impress and they get the "unrecovered document" error and they have to recover the document. From that point forward, the presentation won't run in "Slide Show" mode, at least not on that same terminal.

I think some of them were working directly off of the server: saving/executing. I think that might have slowed things down. I asked them to copy the file onto their desktops and work from there and then save it to their folders. It seemed to work a bit better. >Ah, now that will affect things in a big way.

This has been the 2nd class with Flash and the server has been fine. It looks like that might have been the culprit. During the afternoon (they were on a Linux box), there was no noticable lag.

If you really wanna play with MS Windows, then the Resource Kit traditionally has had info re: registry keys. But seriously--when you have something like GNU/Linux, why the hell waste your time with MS Windows?? :) I do advocate GNU/Linux but getting rid of Windows hasn't been that easy for me. I'll give some reasoning for why. Some decisions are out of my hands like what type of student information system we use because its county wide regulated by the intermediate school district. If it was up to me I would look to implement something more cross-platform like the Kuali project so we could at least think about using Linux for teacher stations. Some labs need to use special software that isn't supported on Linux like Microtype, Clicker 5, and Plato because of lack of authorware plugin. I adopted two W2k3 terminal servers where they had win95 fat clients connecting to the terminal server in a couple labs so I did get some newly donated machines and swap out those with Edubuntu so they could at least experience Linux if they wanted. In the elementary I put in a new lab with donated hardware and did install a Centos ltsp box so they can boot up to Linux with pxe and labeled it the open source lab. I'm using SLED at work because it offers some tools that help me manage e-directory that I couldn't get on other flavors but I always find myself still having to load up a Windows box now and then. I swapped out the webserver and redid the website using Joomla on a Fedora box. So I am fighting the good fight and I hear your battle cries that Windows sucks but its an uphill battle. I do appreciate you and the others on the list for their contributions and collective wisdom and hope GNU/Linux continues to grow and break down those barriers.

The topic has been brought up a few times at our county meetings and some of the concerns were property rights because google now has ownership and worried that google will use this publicly or in a negative way somehow. Some schools even block it completely. I was instructing students to use it for bringing files from home without a flash drive but we started using Netstorage which gives them access to the home folder so now I tell them to use that because of less steps.

Our classroom server has 3G of RAM, and pupils found they could work faster by downloading and working via OpenOffice.org, then uploading at the end of the lesson. But the experience has prompted us to upgrade our broadband connection, we should soon get 5 x the speed for half the cost! We will see if that makes any difference. Google Apps has definitely been advantageous for pupils to work both at school and at home, on any platform, and submit documents for review by their teacher.

I don't believe there is any flash. A lot of ajax though. Your bottle neck could be your internet connection/firewall? We have 4 schools using Google Apps and LTSP.

We just hit a load average of 52 with 30 students logged in and running FF2 and Google Apps. I have no idea why the load average has spiked. Last year was fine, this year with CentOS and the latest flash, it spikes (I have a separate submission for this from earlier in the year). FF3 is even worse based on experience here at NCS. There isn't any swap being used at all, but system is pegged.

In my hosts file on my EL5/K12ltsp server for the server i have 127.0.0.1 server.domain server localhost.localdomain localhost This is identical entry to the FC9 server's host file ( IPv4). On my server when i do a simple ' netstat | grep 6001 ' I get a return of localhost.localdomain:6001 ,, many times of course. for entries that show. On the FC9 server it always comes back with server.domain:6001 Is it possible that 'localhost' never showing is not letting fl_teachertool "see" the logged in TC's on the FC9 server? Thats the only difference I see when running the longer netstat command that you emailed me yesterday between the two. BTW : when I run hostname on my machine it returns server.domain Just curious.

You may have another dhcp server piped into your ltsp network ( and you don't realize it).Do you have static ip's on both eth0 & eth1? Can you see ( you can hit the 'pause' on the keyboard to stop the boot process)that the ip numbers when the client first boots is that of the actual ltsp server?Usually the first ip numbers appear correctly but half way through the boot processs you will see 'phantom' ip numbers( if it is in fact a second dhcp server running on your network). Try plugging in a laptop to your TC's switch. If it's Linux laptop do an; 'service network restart' a couple times. If it's a winders latop do an ; ' ipconfig /release' then an ; ' ipconfig /renew ' a couple times and see what the dhcp server #'s are. If this looks without a doubt correct. then get another switch to try temporarily.Also reboot your k12ltsp server one time just to see if a network restart resolves it. One last thing, you didn't mention how the TC's are booting,,if you are by chance using a floppy disk to boot your TC's make a couple new floppies and pop them in the TC's. From what you are describing this "appears" that this may be the prob.

Did you try switching your network wire into the nic port ,that you "think" it shouldn't go into? When you do an update /kernel ,especially, the nics get reassigned/reversed. You said you "redone" this server? Your dhcpd-ltsp.conf file looks correct. The only other thing that comes to mind is sometimes white spaces ( very rarely) in the dhcp file can cause weirdness without being able to actually 'see' it. If you do an 'service dhcpd restart' a couple times do see the actual 'OK' (green) all the times? If dhcp appears to start but you never see the 'green Ok's ' you have a white space in the dhcp file.

A little Googling shows that you're hardly the only one running into this. The Ubuntu forms have several entries on just this (admittedly annoying) "intelligence" in Nautilus. Apparently it has something to do with the user's locale setting.

I just got one from someone as a sample at LTSP BTS. Didn't occur to me to try to use that. And their pricing seems to be roughly the same as SD cards. Thanks for the suggestion.

I would like to hear Google's feelings on this, since they seem to be interested in education. I raised this question with the school as well. Not a firm legal opinion, but opinion was that for the students it might be ok provided it isn't required to use google docs. And as for the teachers, they are encouraged to not use google docs for any official business at all because of concerns about privacy and proprietary information.

It is convenient, and useful but it is not what I would call secure given the terms of service that google requires you to agree to. Just my (uninformed) two cents.

I have a better understanding of it now, but the fix cited in the first link did not work. First of all, .gnomerc doesn't seem to be read when I log in.

Ten minutes after "yum install sysusage", I have some pretty graphs. Definitely recommended for one-off system monitoring, especially when cacti is such a horrendous pain.

One time i went to older version of tftp and /tftpdir/lts to fix it. The other time the problem was with messed up /etc/hosts file and system inability to resolve the workstation names. Fixing /etc/hosts took care of the problem. yet another option is to create boot files for every terminal - notice that the search for boot file starts with a name based on full mac address.

I believe they are referring to the administrators for the Google Apps account for your domain. And that's no different from having root access to your own servers.

If you want charts and don't like configuring stuff then I recommend using Munin. Install the munin package somewhere and install the munin- node package on all machines you want to monitor.

One of the best and easy to configure and use packages I have seen. -- Regards, Sudev Barar Read http://blog.sudev.in for topics ranging from here to there. PS: I know most of people do not follow email niceties (mostly they are not aware) but if you follow bottom post/in-line post style of email conversations it becomes a whole lot easier to carry on meaningful dialogue and you can snip out what is not meaningful too. Most people just hit reply button and top post leaving prior message appended uselessly at bottom. See if you can adopt this style and persuade others. In case you are already doing this ..... great, spread the message.

BUT there is this huge issue of physical security and confidentiality. IF all the data on the google servers was encrypted, and use of https was mandatory and the google admins did not have the ability to break the encryption and the encryption keys were say stored on local servers that the school controls and access controlled by local passwords/whatever then it might be acceptable to me. I would feel better if everything was managed locally and perhaps stored remotely with all the encryption and access control, but even then who guarantees that passwords aren't compromised? But I am just a volunteer at the school. I may have some influence after 8 years of doing this, but I still don't define the policy. The teachers have been told to not use google apps for anything even slightly sensitive and until an incident occurs I doubt there will be any policy banning google apps.

The performance issues you see are bandwidth for the classroom, not system resource problems. I'm not a huge fan of using Google for anything but search. (Disclaimer: I worked at Google for a while) The paranoid pundits are mostly correct - Google lays claim to EVERYTHING that crosses their wires. Everything is a billboard for ad space to Google. I'm pretty sure that is inappropriate for most schools. Most schools I have seen are very poorly outfitted for high-speed access for the number of online machines. 25-30 PC's sharing a T1 is like dial-up speeds. While cable modem offers high download speeds, actual throughput is determined by the total number of systems on the main line at the pole. Still, a 10M download rate is sufficient for ~100 users (100kbps/user). There are DSL providers that can do that and provide sufficient upstream capacity to not be a blocking issue. Best bet is to use political clout and get local cable monopoly AND local phone monopoly to provide AT NO COST FOREVER the top-speed service they have to EVERY SCHOOL (makes for good advertising and community service and it give the school system lawyers something _productive_ to do). With a setup like that to each school, use a load-balancing firewall.

Message-ID: Hello, I hope everyone is doing well. For those following at home, over the past few years I've been running a k12LTSP server hosting 12 thin clients. It's had its fair share of ups and downs and been a tremendous learning curve. There is now an opportunity to expand the role of the server from just the computer lab it is in to other computers in the building. We're looking to get the classrooms wired up and take some of the existing really old Windows machines and turn them into thin clients running off the server. Now the audience I'm dealing with is not remotely tech-savvy, and first impressions count. I estimate that we'll be going from 12 clients on one 100 MB unmanaged switch to maybe 20 clients through 2 switches or so. The clients range from Pentium I all the way up to Pentium II as they are all machines donated to the Church (I drew the line at the two 486 machines!). Average RAM on the machines is 64 MB. The server is an ASUS p4p800 running a 3 GHz Pentium 4 CPU and has 2 GB of RAM. The server has two 37 GB SCSI Cheetah drives in RAID 1 off a hardware RAID controller. It has 2 Gigabit network cards plus the onboard gigabit NIC (I turned it off because initially when I first installed Linux the onboard one wasn't recognized but modern versions do recognize it). Whenever the system runs slow, the criticism is that it is Linux that is slow, and if we had Windows it would be faster. I, of course, know this is not the case, but this is the perception so I want to make sure it works perfectly when we do the switch. As I am going to be increasing the load on the server, I thought of a number of options that I wanted your recommendations on. 1) Increase server ram to 4 GB This one is probably the most expensive options since we've got 2x1GB sticks in the motherboard so I can't just purchase 2 more GB, I'd have to pull them out and buy 4 new ones. 2) Overclock the ASUS P4P800 motherboard The comments about this motherboard are such that overclocking it is a 'feature' so to speak. All overclocking I've ever seen talked about is in Windows so I don't know how Linux would be affected, if at all, nor would overclocking made a difference to help the load. 3) Replace the 100 MB switch with a gigabit switch The server already has gigabit cards. Many of the thin clients have gigabit cards that I bought and installed. The bottleneck currently is the switch. I saw this 24 port gigabit switch ( DGS 1024D http://www.dlink.com/products/?pid=338) from D-Link for $200. I imagine that this would significantly improve the performance of everything. 4) Bond the server's two gigabit NICs into the switch from #3 I suppose that would increase the output of the server even more. Or, as another option, split the Church into two halves, each half coming through one of the two gigabit NICs (the third onboard NIC would then be for the Internet). 5) ?? Other options I did not consider? What do you think?

I'm confused. Your MB has 4 slots. 2 are currently occupied. Why can't you buy 2 more and populate the other 2 slots. Providing you buy compatible ram to the existing ram. Not sure but that MB/cpu probably doesn't support PAE (Physical Address Extension). So even if you put in 4GB the board may only see 3.6GB or a bit less. Not sure if your cpu will support 64 bit OS. that mb only has pci and an agp. I'm assuming your gigabit nics are in pci slots. There is no point bonding them as the pci bus bandwidth will barely support 1 gigabit nic. You will definitely benefit from gbit uplink port on a switch However, once you get to about 20 clients 4 gb ram is probably okay but your single cpu may suffer. I would recommend upgrading the motherboard and cpu. Dual core cpus are so cheap now (under $100) Get a quad core if you can. But I don't think your mb can handle dual/quad core cpu so you will have upgrade the mb too (another $100) and then your old ram is probably ddr not ddr2. So new ddr2 ram (another ~ $150) Your scsi drives+controller are good though, keep those.

Message-ID: <1228690652.5203.25.camel@localhost.localdomain> Hi Joseph, Sounds like you are getting all your ducks in a row on this gig. Good deal. As everyone has already stated here, when you start going to those numbers of TC's . a GigE backbone at least is a must. 4 gig of ram in your server should be decent. Also what I think you need to think ahead on is how are you going to boot all these older machines? floppies. rom chipped pci nics? If these machines are that old I would suggest an easy out option and just do eb_on_hd. It's a no brainer 2 step process that installs etherboot onto the existing hd of each of your machines. The only caveat, just to get eb_on_hd installed you will have to temporarily hang a floppy off of each on the machines to do the install so there will be a little legwork involved. It takes 5 mins to do a machine, FYI. The upside is this will breathe new life into an otherwise dumpster bound PC. These older machines will be plenty adequate for 95% of your users,,,but be prepared. You will always hear." These machines are old and junk". Maybe spray paint them all black,and they'll never know the difference:-) >From my experience at the school I am at, kids will tear up new $900 pc's just as easy as the older ones,bottom line. Sounds like you'll have plenty of spares lying around so in case a PS dies or whatever you can just pitch the old, in with new...kinda:-) One other thought, if the higher ups,do not want to pop for new server iron, if you have another decent older server to use,would be to run two k12ltsp servers in parallel on your network for failover,as well as load balancing. This would illeviate you doing all the nic bonding stuff as well. You would of course have to set up a homes folder config on one or the other with this setup. This setup at least gives you two pipes going to x number of TC's versus only one pipe. Downside, a little more maintenance on your part. Just some thoughts. Good Luck.

In-Reply-To: References: Message-ID: <493C7610.1070909@cmosnetworks.com> New server. Definitely. If you want to make a good impression, that is. Go for at *least* 64-bit dual core, and preferably quad core. New motherboards that support this very often have twin Gig-E ports that you can channel-bond. 4GB is your minimum DRAM, and if you can do 6GB, then I'd go for it. The reason is file caching. You don't want to touch the hard disk any more than you have to. Also, I second (or third?) the Gig-E direction you're getting. Gotta do it. And most definitely get a switch with at least two Gig-E ports, preferably one that supports channel-bonding. **Make sure your wiring is good Cat 5 or better!** Note: all of this will be significantly less money than getting new PC's preloaded with Windows Vista. --TP _______________________________ Do you GNU ?

We choose to continue and it seems to work anyway though. I didn't see a big difference in the load on the system with just a few accounts being used. I also tried Konqueror and that wouldn't work at all with Google Apps, not sure what settings would have to be tweaked.

I am told by one of the teachers who is sympathetic to FOSS that he has been told that Power School is in the process of making PS browseable. At that point, the problem will go away.

PS: I know most of people do not follow email niceties (mostly they are not aware) but if you follow bottom post/in-line post style of email conversations it becomes a whole lot easier to carry on meaningful dialogue and you can snip out what is not meaningful too. Most people just hit reply button and top post leaving prior message appended uselessly at bottom. See if you can adopt this style and persuade others.

There currently does not exist a 64-bit version of Sun's Java plugin. I don't know if nspluginwrapper supports running the 32-bit plugin in a 64-bit browser, but you could look into that.

Some of the early PXE implementations were broken. I know I had to flash the Bios on my Dell GX1s to get them to PXE boot. From what you are saying, you are getting an IP address but not getting a boot file from TFTP. Is there anything else on your network giving out IP addresses, like a linksys router?

One of the first 5-6 lines. If you don't see pxe v2.0 or v2.01 this client will never boot. A workaround if you cant get it bios updated,is to build a floppy image(I would guess this old PC has a floppy in it),with the correct nic image from the /tftpboot/boot/bootroms/ ,or just build the universal boot floppy, also contained in this directory. This is on your k12ltsp server right now. This will at least make this machine bootable for you to test on. If nothing else you'll learn how to build floppy images,& or the Universal Boot floppy.:-) Take Care, Barry Cisna From peter at scheie.homedns.org Wed Dec 10 15:26:55 2008 From: peter at scheie.homedns.org (Peter Scheie) Date: Wed, 10 Dec 2008 09:26:55 -0600 Subject: [K12OSN] Power School????

As project manager for SchoolTool, I'll note first that we've released a beta of our basic student information system -- see http://schooltool.org We'll be continuing steady development (we have funding for two developers in 2009) up through the spring and summer, so there's time to fill in the remaining gaps. Also, the Commonwealth of Virginia just released an RFP for a $40,000 statewide pilot of CanDo, an open source competency tracking system that's a component of SchoolTool, so we're getting some momentum. The more established players are Centre and its many forks, and Open Admin (http://richtech.ca/openadmin/) --Tom From accessys at smart.net Wed Dec 10 15:44:02 2008 From: accessys at smart.net (Accessys@smart.net) Date: Wed, 10 Dec 2008 10:44:02 -0500 (EST) Subject: [K12OSN] Power School????

Message-ID: <494012FD.8010306@cmosnetworks.com> Apparently a kid was handing out Linux LiveCD's and got them confiscated by a very angry teacher who called it "disruptive" and even "illegal". http://linuxlock.blogspot.com/2008/12/linux-stop-holding-our-kids-back.html I quote the US Supreme Court in Tinker vs. Des Moines, 1969: "In our system, state-operated schools may not be enclaves of totalitarianism. School officials do not possess absolute authority over their students. Students in school as well as out of school are 'persons' under our Constitution. They are possessed of fundamental rights which the State must respect, just as they themselves must respect their obligations to the State. In our system, students may not be regarded as closed-circuit recipients of only that which the State chooses to communicate. They may not be confined to the expression of those sentiments that are officially approved. In the absence of a specific showing of constitutionally valid reasons to regulate their speech, students are entitled to freedom of expression of their views. As Judge Gewin, speaking for the Fifth Circuit, said, school officials cannot suppress 'expressions of feelings with which they do not wish to contend.' Burnside v. Byars, supra, at 749." This makes me sick. Sick that such people are allowed to teach our kids. --TP _______________________________ Do you GNU ?

Nice script! - over my head but I waded through this with my home setup that I use to test before even doing updates at school. A new version of firefox did it to me a month or two ago at home... I'm running a 32 bit version of Firefox out of /opt on my 64 bit systems now with all of the plugins working... Everything was fine until the update that included a newer Firefox. I knew I shouldn't have let into the update. Just too tired to think! Today I've got the same problem on one of my three production servers. I let Firefox update and now all of my plugins are trashed in K12LTSP... This is in another thread.

I didn't quite understand? There may be something to the repo install that causes this. All the time I've always just used the same rpm flash plugin and have never experienced this on several Centos5 32-bit install through FF v 3.04. Also I believe I understand you right that this ONLY happens when logging into an gmail account,and no other flash sights? One thing that puzzles me is why when you do the ' about:plugins' in FF you are not seeing a listed flash plugin available. I believe you should be seeing something like the following: (This is copied from FF-3.0.4) and have looked this way since FF-1.5.0. All of our servers show exactly the below. ---------------------------------------------------------------------- Shockwave Flash File name: libflashplayer.so Shockwave Flash 9.0 r31 MIME Type Description Suffixes Enabled application/x-shockwave-flash Shockwave Flash swf Yes application/futuresplash FutureSplash Player spl Yes ---------------------------------------------------------------------- Why don't you compare your /usr/lib/mozilla/plugins and your /usr/lib/FF3.0.4/plugins dir and see if they look identical?

Here's the actual paths that I need to copy: /usr/local/share/icons/Drawings.desktop /usr/local/share/icons/Obsolete\ Drawings.desktop /usr/local/share/icons/Obsolete\ a\ Drawing.desktop Since it's only 3 files, I could do as Robert suggests: > cp /path/file1 /path/file2 /path/file3 /dest/dir But I was hoping to find a way with less typing, just in case someday I have to do this with 10 files instead of 3.

Squidguard in a squid plugin that will do filtering (Dans guardian is another filter, but I haven't used it). squidguard is highly configurable, and it will log who goes where. You can specify time periods, ip addresses, usernames (though I never tried that). It operated off blacklists and whitelists. I really liked it and am getting ready to deploy it on my network. When I get time. For remote admin, use ssh. squid and squidguard can both be managed from the command line, so ssh will work just fine for that. -- Jim Thomas Principal Applications Engineer Bittware, Inc jthomas at bittware.com http://www.bittware.com (603) 226-0404 x536 I'm a man.

With URL Filter (based on Squid) performing transparent proxying and BOT blocking (or restricting) all ports that the proxy doesn't handle, all traffic is logged by the firewall, proxy and by URL filter. The Advanced Proxy plug-in can be used with LDAP so user's could be made to authenticate (we don't do that, yet) and have their IDs logged along with their access. Not a lot of wiggle room, biggest headache is closing down access to "proxy tunnels", but analyzing the Squid logs with Webalizer (logs shipped via ssh to management station daily for analysis) turns them up eventually. BOT takes a bit of time to set up rules, but it is very effective. Update accelerator really saves bandwidth; first download seeds the cache, subsequent updates fed from the cache. The plugin on IPCop checks for updates to updates in it's cache independently. Handles Window$, Linux, Mac, Avast, and Symantec updates. -- "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 wtogami at redhat.com Fri Dec 12 04:18:32 2008 From: wtogami at redhat.com (Warren Togami) Date: Thu, 11 Dec 2008 23:18:32 -0500 Subject: [K12OSN] Testing Needed: ltsp-5.1.37 and ldm-2.0.22 Message-ID: <4941E618.5020802@redhat.com> http://kojipkgs.fedoraproject.org/packages/ltsp/ http://kojipkgs.fedoraproject.org/packages/ldm/ http://kojipkgs.fedoraproject.org/packages/ltspfs/ Please test the latest versions of these packages. It should maintain all previous features for existing users, but it adds a few exciting new features and capabilities like: * It is now possible to set a non-GNOME default desktop session for all new users. lts.conf now contains LDM_GLOBAL_DMRC=/etc/ltsp/ldm-global-dmrc, or you must add it manually if you have upgraded from a previous version. You can edit that file to specify a particular non-GNOME desktop session or language. A few examples are included commented out. * If the user selects a desktop session or language, it now asks if they want to save that choice for future logins. It is saved to ~/.dmrc in the user's home directory. Delete that file if you want the user to fall back to the LDM_GLOBAL_DMRC defaults. * All of the X_* lts.conf options should now be supported now, although this functionality is less proven at the moment. Please report back if you have tried these updated packages. I want to hear a few "IT WORKS" reports on both F-9 and F-10 before pushing to updates.

You could check if the current working directory is the directory you want it to be, using the pwd command. #!/bin/bash TARGET_DIR=/some/directory cd $HOME if [ `pwd` == $TARGET_DIR ]; then echo "OK" else echo "Not OK" fi You could also use the $? variable to check the exit code of last command $ cd $HOME $ echo $? 0 $ cd non-existent-directory -bash: cd: non-existent-directory: No such file or directory $ echo $? 1 Or in a script: #!/bin/bash TARGET_DIR=/some/directory cd $HOME if [ "$?" == "0" ]; then echo "OK" ... do some stuff in the $TARGET_DIR ... else echo "Not OK" fi I haven't tested a line of code in this post, but the general idea is clear, I hope.

It should maintain all previous features for existing users, but it adds a few exciting new features and capabilities like: * Oops, yesterday's ldm-2.0.22 broke LDM_DIRECTX=true which is the default config for Fedora. This has been fixed. * LOCAL_APPS_WHITELIST now makes it possible to limit commands you can run as a local app. Almost nobody needs this option, but it is at least possible now. * It is now possible to set a non-GNOME default desktop session for all new users. lts.conf now contains LDM_GLOBAL_DMRC=/etc/ltsp/ldm-global-dmrc, or you must add it manually if you have upgraded from a previous version. You can edit that file to specify a particular non-GNOME desktop session or language. A few examples are included commented out. * If the user selects a desktop session or language, it now asks if they want to save that choice for future logins. It is saved to ~/.dmrc in the user's home directory. Delete that file if you want the user to fall back to the LDM_GLOBAL_DMRC defaults. * All of the X_* lts.conf options should now be supported now, although this functionality is less proven at the moment. Please report back if you have tried these updated packages. I want to hear a few "IT WORKS" reports on both F-9 and F-10 before pushing to updates.

Message-ID: <1229271141.2982.13.camel@localhost.localdomain> Hi Bob, Here is a strictly web based SIS product. Centre/SIS. I have followed this and played with it quite a bit over the last four years. It does everything PowerSchool does and more. They now have the lunchline module included as part of the package. It IS an active/developing product,so I think it will be around for some time. Example our school just spent about 45K to convert to a web based SIS product( with yearly recurring cost per student of course), and another 20K to convert to a 'better' lunchline program. I have NO say so in any decisions. Hence the uppers like to go 'commercial'. Have you ever heard the phrase "You are beating a dead horse"?:-) Centre/SIS does what these two products the school bought and more. Price $0. Runs on a Postgresql database.Easy to setup really and you have to purchase the state reporting modules (if your state requires this) but very minimal for all the functionality you are getting. BTW: The Web2School looks very nice too. Only thing that I see, just a tad iffy is the Java stuff required to run Web2School. Shouldn't be a big deal,though.

As we're connecting to a site, it says the site can't be reached and you have to try again until it goes through. I've mentioned it to the people in charge, but they haven't really acknowledged the problem. It seems to be that it's only an issue with web connections, like they're running a cache server that can't handle the load or something. Is there any way to run a test of connections through http, much like ping does, that would produce a list of how many connections made it to the website and how many got dropped so I could present them with a printout that says only 60% (or whatever) of the websites we try to go to actually make it?

My plan will be to install Squid + Squidguard for the filtering and local caching. I like the black/white listing feature that it has so that should be a big boon for us. To do this, I've been reading about the hardware requirements. I understand that in terms of decreasing priority, it is RAM > Hard Drive > CPU speed. The part I'm confused about is the network configuration. Is this machine suppose to have 2 network cards (one in, one out) for maximum throughput? Also, where is this machine suppose to exist on the network? My setup is as follows: 1) cablemodem -> switch 2) Switch has LTSP internet NIC plugged into it 3) same switch has the windows computers that need internet access plugged directly into it. so would the squid machine go between the cablemodem and the switch?

They would be useful again if they were LTSP thin clients, logging into a modern x86_64 terminal server. So I tried to make them boot as thin clients using LTSP and standard Fedora ppc components. The next release of ltsp will automatically build a thin client chroot in /opt/ltsp/ppc with the ltsp-build-client command. The idea is that you could copy that /opt/ltsp/ppc chroot to your x86_64 server that handles ordinary i386 client netboot, and through dhcpd.conf trickery it could serve netboot to the PPC clients. Unfortunately I couldn't get it to work." Read the blog for details. If anybody has further suggestions of stuff to try I'm all ears.

The model I got to work very easily was the Imac Indigo's. These are the dull cased, kiddy colored all in one case models. These have the slotload CD's in them is the easiest way i know to distuguish them. I got 24 of these to work fine,along with sound. Sound worked on Tuxtype.etc,as well. I never did try flash. This has been almost 4 years ago,and flash was dodgy at best even on PC's. I did NOT have to do any bios updating on any of them and they all had different version bios's on them just to verify this. The key on getting these to boot is learning the mac Openfirmware( I think) is what it is called, You can save the parameters,permantly as you like and they reboot every time with the parameters you feed it. I tried pretty hard to get Emacs, (which we had 20 of), to work and never had any luck with these. The Imac indigos do make very nice All in one machines that are very speedy. There are tons of these lying around in storage closets ,I'm sure. Here is a link to a 'how to' I done,on how to get sound working on the Imac Indigo All in One's; http://wiki.ltsp.org/twiki/bin/view/Ltsp/SoundCards#Sound_on_Imac_Indigo_as_a_thin_c Hope this helps a little.

FYI the Notebook galleryitem files are really just SCORM (ver. 2004) files (which are in zip archive format). Apparently Moodle has a SCORM 2004 player module. So if anyone who has Smartboards and Moodle might want to see if they load. You'd have to change the suffix from galleryitem to zip I believe. I'd like to see this work personally since they have NO interest in making Flash work in the Notebook for Linux. Feeling a little burned.

Hi I would replace the switch with a router (a cheap linksys). I don't really trust that the newer cablemodem/router combinations are very secure. It will stop the bulk of silly attacks. I would place the squid machine in-line so that all internet access has to flow through that device. In your example between the switch and cablemodem makes sense. My setup is as follows: CableModem -> Router -> IPCop Firewall -> Switch Into the switch I have two LTSP servers public network connection (firewall rules applied). Currently all our Windows and Apple computers are in the private network of the LTSP servers with IP forwarding. I currently run DansGuardian with Squid and Squid Guard on the LTSP server and all internet access flows through that. I am rethinking that after realizing that DansGuardian with virus scanning enabled put an unacceptable load on an LTSP server equipped with a Quad core Xeon and 8 GB of Ram. Disabling the virus scanning reduced the load significantly. If I was to redesign and have the hardware I would do: CableModem -> Router -> IPCop Firewall -> Switch -> Router[0] -> LTSP Server[0] -> Router[1] -> LTSP Server[1] The placement of Router[0] and Router[1] serves to separate LTSP servers if they have different uses and security needs (which mine do). Of course, a small firewall would replace a number of components. If the system was sufficiently powered, I would run DansGuardian on IPCop or place it between the IPCop firewall and the switch. Given the performance hit I saw, I probably would not run DansGuardian on the terminal server. If you are able to use the separate machine you may be able to enforce the proxy use via iptables. The only other thing I have been doing lately is using OpenDNS.org for the DNS. It allows you to setup web filtering as well which is nice because it adds another level of filtering without an impact on your servers.

You misunderstand. The client only does X, pulseaudio for remote sound and ltspfs for remote storage. Plugins run on the server across the network, where you would have your modern beefy x86_64 server. EL5 ppc is well supported, but far fewer people use it as a desktop thus it is not likely to be a better platform for PPC clients. Fedora's kernel and/or yaboot needs fixes for netboot apparently.

I take it that you then don't anticipate problems either with the 64-bit implementation of java or flash. Other than conceiving of this as a good and practical idea, have you had experience doing this with actual PPC clients on an x86_64 server? > > EL5 ppc is well supported, but far fewer people use it as a desktop thus it > is not likely to be a better platform for PPC clients.

Matter of fact, I've had x86, PPC, and even UltraSPARC boxes running as thin clients...from the same K12LTSP server...simultaneously. :-) Basically, I had to build a custom /etc/dhcpd.conf for it and copy /opt/ltsp/ppc and /opt/ltsp/sparc over. That, and make an /etc/hosts file that would accommodate it. But it really was not very hard. --TP -------------- next part -------------- An HTML attachment was scrubbed...

For some reason, the SMC gateway router will not connect to the internet unless I load into the d-link router the information for the static IP address we have from the ISP. I have tried to plug a network cable from a computer directly into the SMC from a computer but it doesn't let me access any web administration page or anything else. I have no idea what the issue is -- I have tried to reboot the gateway with the reset button on the back but to no avail.

Depends on your level of paranoia. The SMC seems to be a combo cable modem and router. If it is provided by the cable company I would not trust the configuration. Trusting them to be too busy to attack your network is one thing but trusting that they will not accidentally leave it wide open after some firmware update is quite another thing. If you own the SMC and the configuration options he needs are there (It does not seem that they are) then you would not need the D-Link. My preference is to place my first line of defense in a router that I own just to stop the majority of the dumb attacks. The second line would be a firewall/proxy machine. It is important to note, that depending how the proxy is configured, it may provide no network protection. Without a hardened OS and firewall on the proxy it may merely be doing content filtering of we surfing.

I don't have this with Ubuntu and LTSP 5 (but it should be similar) but in my older system I simply enabled IP Forwarding in the kernel options and the LTSP server forwards the internet traffic for the non LTSP clints. See: http://www.ducea.com/2006/08/01/how-to-enable-ip-forwarding-in-linux/ If the Windows clients get a dhcp address from the LTSP server on the thin client network they can get to the internet via the LTSP server. In a two NIC setup with firewall rules applied to the "Internet" nic, it further protects your clients by moving them further into your network. Of course, moving Windows clients into that trusted area is probably not a good idea without a combination of good web filtering, antivirus and non admin users. My windows systems are mostly servers so it kind of makes sense.

The dual CPU Atom 330 based motherboards should make even better thin-clients.

Message-ID: Hello, How are you? I hope you are all doing well. I figure after lurking for a while it was time to get all my questions out. :) It ends up that our new LTSP network has two groups of clients (currently existing LTSP room A and a new room of thin clients in room B). Each room has a switch. There are 2 cables that then run from room A and B to a common server room where the LTSP server is. Originally the LTSP server was in room A serving only that room. Our LTSP server has 3 network cards. Currently one of those cards is not active. The second NIC plugs into the switch for the thin clients and the last NIC plugs into the router for Internet access. How do I activate that 3rd NIC card as a second thin client card? That way NIC A serves room A and NIC B serves room B and NIC C access the internet for room A & B? I wasn't able to search for this because I didn't know what this process was called -- I didn't think it was network bonding. Thank you.

In-Reply-To: References: <33e277440812190520l1aa78c03s15e17b96442dd917@mail.gmail.com> Message-ID: <494BE3FB.4000204@cmosnetworks.com> This is exactly how I did the PPC/x86/SPARC K12LTSP server a while back, and yes, it would work wonderfully for your situation. Basically, you'd need to do this: 1.) Set up your third NIC for another client subnet (e. g. 192.168.4.0/24), and hook 'er up to that switch. 2.) Modify /etc/hosts to include host entries for the 192.168.4.0 range, just like the ones for 192.168.0.0 are today. 3.) Create a second DHCP scope in your /etc/dhcpd.conf file. I just copied the info from the first scope, changing "192.168.0" to "192.168.4". Since all the clients are x86 in your case, you don't need to change any directory path info (just keep using /opt/ltsp/i386). 4.) TRIPLE-CHECK THAT YOUR THIRD NIC IS PLUGGED INTO THE RIGHT SWITCH! You don't want to be handing out LTSP client addresses to the main LAN. That would be bad. 5.) Restart DHCPD and try booting a client. And you're right, 802.1q is indeed VLANs, and yes, it would work if you had the hardware. But then you run into a scalability problem. I'm assuming that the interfaces on your server are Gig-E or lower (Ten Gig-E is still very expensive). Thus, it's not too hard to put enough clients on a LAN segment to saturate that Gig-E line. Fifteen simultaneous TuxType sessions will do it, as would anything else with lots of screen updates (e. g. video streaming or ChildsPlay). Using that second NIC will give you the bandwidth needed to support that second set of clients in the other room. Note that this is not channel-bonding. This is just good ol' fashioned separate interfaces on separate broadcast domains. There doesn't seem to be any need to channel-bond here. --TP _______________________________ Do you GNU ?

You will need to ensure that the hostnames are unique. I didn't point that out. So, while your /etc/hosts file might look like this: 192.168.0.1 ws001 192.168.0.2 ws002 and so on... I would tweak the hostnames to look like this, by adding a digit, like so: 192.168.0.1 ws0001 192.168.0.2 ws0002 192.168.4.1 ws4001 192.168.4.2 ws4002 See the difference? In this case, the first digit after the "ws" reflects the third octet of the subnet. That tells me very quickly which subnet a client is on, just by looking at the hostname. Could be handy for troubleshooting. Of course, you can use any scheme you want, as long as the hostnames remain unique. --TP _______________________________ Do you GNU ?

Often times the congestion on your server is not at your dual or core or octa CPU or in your RAM or in your disk I/O. It is at your single NIC, even if it's a giganic, trying to serve all that data.

Reason is that there aren't any network services (e. g. SSH, httpd) to which the clients connect. They're thin clients. That might be different with LTSP 5, though, since it encrypts everything in SSH tunnels. I just haven't tried it yet (no time). --TP _______________________________ Do you GNU ?

Make sure on the ssh key config,you click on "import" then navigate to your /etc/nxserver/client.id_dsa.key and 'Save'! Next do ' service sshd status ' make sure ssh is actually running.

There was a piece of info I left out. Because you now have more than one DHCP scope, you've got to be careful with your global options (those not in a "shared-network XXXXXX" section). Basically, you've got to move all those "option" statements for 192.168.0.0 into the "shared-network WORKSTATIONS" section, and the "option" statements for 192.168.4.0 into the "shared-network WORKSTATIONS-2" section. The reason is that all the global statements for 192.168.4.0 just over-rode all your statements for 192.168.0.0, so your 192.168.0.0 thin clients would've had problems, too. Sorry 'bout that. Here's the tweaked version. Give this a read and see how it goes. Also, what types of clients are you using--EtherBoot or PXE-boot? # Sample configuration file for ISCD dhcpd # # Don't forget to set run_dhcpd=1 in /etc/init.d/dhcpd # once you adjusted this file and copied it to /etc/dhcpd.conf. # # File was modified by Joseph Bishay December 19th, 2008 to add a second subnet for the church 192.168.4.X/24 default-lease-time 21600; max-lease-time 21600; ddns-update-style none; allow booting; allow bootp; # "option" statements for 192.168.0.0 moved # to shared-network WORKSTATIONS{} section # This part below is duplicated by Joseph # "option" statements for 192.168.4.0 moved # to shared-network WORKSTATIONS-2{} section # End of duplication shared-network WORKSTATIONS { subnet 192.168.0.0 netmask 255.255.255.0 { range dynamic-bootp 192.168.0.100 192.168.0.253; use-host-decl-names on; option log-servers 192.168.0.254; # Moved those option statements from global to scope-specific option subnet-mask 255.255.255.0; option broadcast-address 192.168.0.255; option routers 192.168.0.254; option domain-name-servers 192.168.0.254; next-server 192.168.0.254; option domain-name "ltsp"; option root-path "192.168.0.254:/opt/ltsp/i386"; option option-128 code 128 = string; option option-129 code 129 = text; option option-221 code 221 = text; # End option statements from above for 192.168.0.0 # trick from Peter Rundle # newer Macs if substring (option vendor-class-identifier, 0, 9) = "AAPLBSDPC" { filename "yaboot"; option vendor-class-identifier "AAPLBSDPC"; } # really old iMacs elsif substring (option option-221, 0, 5) = "Apple" { filename "yaboot"; option vendor-class-identifier "AAPLBSDPC"; } # Intel PXE elsif substring (option vendor-class-identifier, 0, 9) = "PXEClient" { # NOTE: kernels are specified in /tftpboot/lts/pxe/pxelinux.cfg/ filename "/lts/pxe/pxelinux.0"; } # default to an i386 BOOTP image else { filename "/lts/vmlinuz.ltsp"; } if substring (option vendor-class-identifier, 20, 3) = "ppc" { option root-path "192.168.0.254:/opt/ltsp/ppc"; } else { option root-path "192.168.0.254:/opt/ltsp/i386"; } } } # example configurations for specifying specific kernels to specific clients group { use-host-decl-names on; option log-servers 192.168.0.254; host ws001 { hardware ethernet 00:E0:06:E8:00:84; fixed-address 192.168.0.1; filename "/lts/vmlinuz.ltsp"; option option-128 e4:45:74:68:00:00; option option-129 "NIC=3c509"; } host ws002 { hardware ethernet 00:D0:09:30:6A:1C; fixed-address 192.168.0.2; filename "/lts/vmlinuz.ltsp"; option option-128 e4:45:74:68:00:00; option option-129 "NIC=ne"; } host ws003 { hardware ethernet 00:D0:09:30:28:B2; fixed-address 192.168.0.3; # kernels are specified in /tftpboot/lts/boot/pxe/pxelinux.cfg/ filename "/lts/boot/pxe/pxelinux.0"; } # Apple Specific Settings # host ws007 { # hardware ethernet 00:30:65:69:23:60; # fixed-address 192.168.0.4; # option root-path "192.168.0.254:/opt/ltsp/ppc"; # filename "yaboot"; # option vendor-class-identifier "AAPLBSDPC"; # } } ##### # Second part of duplication by Joseph Bishay #### shared-network WORKSTATIONS-2 { subnet 192.168.4.0 netmask 255.255.255.0 { range dynamic-bootp 192.168.4.100 192.168.4.253; use-host-decl-names on; option log-servers 192.168.4.254; # Moved those option statements from global to scope-specific option subnet-mask 255.255.255.0; option broadcast-address 192.168.4.255; option routers 192.168.4.254; option domain-name-servers 192.168.4.254; next-server 192.168.4.254; option domain-name "ltsp"; option root-path "192.168.4.254:/opt/ltsp/i386"; option option-128 code 128 = string; option option-129 code 129 = text; option option-221 code 221 = text; # End option statements from above for 192.168.4.0 # trick from Peter Rundle # newer Macs if substring (option vendor-class-identifier, 0, 9) = "AAPLBSDPC" { filename "yaboot"; option vendor-class-identifier "AAPLBSDPC"; } # really old iMacs elsif substring (option option-221, 0, 5) = "Apple" { filename "yaboot"; option vendor-class-identifier "AAPLBSDPC"; } # Intel PXE elsif substring (option vendor-class-identifier, 0, 9) = "PXEClient" { # NOTE: kernels are specified in /tftpboot/lts/pxe/pxelinux.cfg/ filename "/lts/pxe/pxelinux.0"; } # default to an i386 BOOTP image else { filename "/lts/vmlinuz.ltsp"; } if substring (option vendor-class-identifier, 20, 3) = "ppc" { option root-path "192.168.4.254:/opt/ltsp/ppc"; } else { option root-path "192.168.4.254:/opt/ltsp/i386"; } } } ####### # End of second duplication by Joseph Bishay # with slight mods by Terrell Prude' ####### --TP Joseph Bishay wrote: > Hello, > > I followed your steps but something seems to be wrong. > > I activated the 3rd NIC, made the changes to hosts and the > /etc/dhcpd-k12ltsp.conf (/etc/dhcpd.conf is blank in my k12ltsp FC6 > setup) > > I rebooted the server, then turned on one of the clients.

Better to have the info and not have to guess. I see one thing right away, in /etc/hosts. 1.) You do need an entry for 192.168.0.254. 2.) You also need another entry for 192.168.4.254. Both of these IP addresses can point to "server.ltsp". Now, as for dhcpd startup failing, can you take a look at /var/log/messages and see what error messages you're getting when you try to start dhcpd? I'm not seeing anything in your config that stands out as "bad". --TP _______________________________ Do you GNU ? Microsoft Free since 2003 --the ultimate antivirus protection!

It sounds like people go the route you have chosen. However, VLANs would work and don't need to be used JUST for breaking down large networks. This would work perfectly especially if you were doing layer 3 routing. There is no scalability issues as mentioned before...except hardware (ie you can't do VLANs on your hardware or your hardware doesn't support enough VLAN creations for the size of your network). I would be happy to discuss this with anyone if someone wished to pursue this route and had questions. /paul On Fri, Dec 19, 2008 at 10:56 AM, Joseph Bishay wrote: > Hello, > > 802.1q, or as I understand it -- VLANS -- would also do the same idea > so to speak.

Have you changed sshd from the default of port 22 to 777? If so you have to make changes to your /etc/nxserver/node.conf file to reflect this at,SSHD_PORT=###. (there is an node.conf.sample file at /etc/nxserver). If you have changed your sshd.conf file to port 777,why don't you switch back temporarily to the default port 22, restart sshd 'service sshd restart' and try and connect with nx and see if you get a successful login now. If you are successful this way then start modding your sshd.conf and your node.conf files.

That is two letter "V"s as in verbose, more verbose. I find that to be helpful when debugging ssh connections. For instance, more verbose will even tell you if permissions are incorrect on your id file.

That said, we do use inter-VLAN routing to keep the "open SSID" wireless network away from anything on the school LAN while still providing Internet connectivity (Internet Web and DNS only). VLANs are indeed very cool and very useful, and I love 'em. --TP _______________________________ Do you GNU ? Microsoft Free since 2003 --the ultimate antivirus protection!

SOME SUCCESS! Message-ID: Hello, So I've been tearing out and rebuilding most of the I.T. in the building for the past few days. My goal is to have it all up again by the end of this week. A lot of postings were about how it was a bad idea to be running K12LTSP fedora core 6 as the main machine, so I took this opportunity to backup and then wipe the LTSP server. I've installed a clean K12LTSP CentOS EL version on it and tried to set it up from the start for 3 NIC functionality. (I've also installed both IPCOP with squidguard and another centos webserver/mailing list so it's been a busy few days!) Back to the 3-NIC problem. I noticed that somehow, something was crossed with all the cables going in and out of the switch, and I think at some point an Internet connection from the router was plugged into the LTSP switch. Not sure if this was affecting the TFTP or not, I pulled out all the cables and just plugged in one client and the server into the switch. I was able to get, when I plug the switch into the default LTSP NIC, to get a client to boot. Well, technically it failed with some sort of failed to find the opt/i386 kernel or such and gave you 4 possible fixes. Hunting through the email archive the solution was to modify /etc/exports to add two lines for /opt/ltsp/i386 and /var/opt/ltsp/swapfiles for the secondary network. I also went into lts.conf and added TWO server lines: server = 192.168.2.254 AND server = 192.168.3.254. Doing that got the client to boot so half the problem is solved! Now, the question becomes, why when I plug the switch into the secondary LTSP NIC, do the clients hang at 'loading 192.168.3.254:/lts/vmlinuz/ltsp"? I assume that tftp is working since they do boot when plugged into the other NIC. Just to clarify -- when I installed CentOS, I setup the networks as follows: eth0 - 192.168.2.XXX - LTSP network No. 1 - works fine! eth1 - Internet NIC eth2 - 192.168.3.XXX - LTSP network No. 2 - hangs! So close to a solution!

I might've even forgotten to tell you to modify that file. Also, each subnet's lts.conf file needs only one "server = " entry. That would be the IP address applicable to that subnet. Oh, one other thing: when I did this, I had the following three directories: /opt/ltsp/ppc /opt/ltsp/i386 /opt/ltsp/sparc which meant that each segment's DHCP scope entry pointed to a separate directory. That is, 192.168.0.0 pointed to /opt/ltsp/i386, 192.168.2.0 pointed to /opt/ltsp/ppc, and 192.168.3.0 pointed to /opt/ltsp/sparc. Try this: Make a copy of your entire /opt/ltsp/i386 directory and call it, say, "/opt/ltsp/i386-3". Then, tweak your /etc/dhcp.conf file to point the 192.168.3.0 scope to "/opt/ltsp/i386-3" instead of "/opt/ltsp/i386". Of course, ensure that the lts.conf file in /opt/ltsp/i386-3 contains the appropriate entries for 192.168.3.x. Again, you only need one "server = " entry per lts.conf file. > Now, the question becomes, why when I plug the switch into the > secondary LTSP NIC, do the clients hang at 'loading > 192.168.3.254:/lts/vmlinuz/ltsp"?

SOME SUCCESS! In-Reply-To: References: <49527DF7.7080008@cmosnetworks.com> Message-ID: <49528BE1.6060203@cmosnetworks.com> I see one problem with /etc/exports. Change this line: /opt/ltsp/i386 192.168.3.0/255.255.255.0(ro,no_root_squash,sync) to /opt/ltsp/i386-3 192.168.3.0/255.255.255.0(ro,no_root_squash,sync) and make sure that you've copied /opt/ltsp/i386 to /opt/ltsp/i386-3! You need a *separate* /opt/ltsp/ directory for each client's subnet. So, just do a "cp -Rpv /opt/ltsp/i386 /opt/ltsp/i386-3", and that should do it. After you do that.... Then modify your /etc/dhcpd.conf file, which we did earlier this week, to point your second scope (192.168.3.0, in your case) to /opt/ltsp/i386-3. Restart DHCPD. Then (no, you haven't tried booting a thin client on 192.168.3.0 yet!), modify /opt/ltsp/i386-3/lts.conf so that there is only one "SERVER = " line. Make sure that this points to 192.168.3.254. *Now* try booting a thin client on both 192.168.2.x and 192.168.3.x and let us know. --TP _______________________________ Do you GNU ?

That should be checked as well. My apologies. I dropped out of this thread until today. As I mentioned in my first posting on this, I had to edit hosts.allow in order for my tri-nic setup to work when I've done it in the past. At least I thought so. I just did a quick google, and when we solved this on the list in 2005 https://www.redhat.com/archives/k12osn/2005-August/msg00871.html I apparently took only the following 5 steps. Not included is editing hosts.allow. If you have done the 5 steps below, and it is not working, then I'm going to set one up this afternoon and document it better. "In summary, should one want to have two NICS serve thin clients, 1. Edit settings for eth1 2. Edit dhcpd.conf to include eth1 IP settings 3. Edit /etc/exports to share on the eth1 subnet 4. Edit firewall settings to make eth1 a trusted device 5. Edit /etc/hosts to include settings for the eth1 subnet" > > --TP --scott From joseph.bishay at gmail.com Thu Dec 25 00:49:58 2008 From: joseph.bishay at gmail.com (Joseph Bishay) Date: Wed, 24 Dec 2008 19:49:58 -0500 Subject: [K12OSN] LTSP server with 3 NICs?

I'll try to go through them all here. 1) dhcpd-k12ltsp.conf Terrell, you are correct I forgot to paste it in -- my apologies. I have pasted it in at the end to not make this message too messy. 2) iptables -L as root I didn't actively change anything from the stock installation for the iptables. Something, however, may have changed it inadvertently.

Is this different from the iptables rules? This is the one that got me. From a terminal, as root or with sudo, run system-config- securitylevel. Here you can choose your 'trusted interfaces' You want your two LAN NICS to be trusted. So, if eth0 and eth1 are the nics with your LAN IP settings, then make them the trusted interfaces. You've gotten some great help so far and, without looking in detail, I believe that everything else is okay. Let's try the firewall stuff and then dig deeper if needed. > > Thank you. > Joseph --scott From joseph.bishay at gmail.com Thu Dec 25 01:58:28 2008 From: joseph.bishay at gmail.com (Joseph Bishay) Date: Wed, 24 Dec 2008 20:58:28 -0500 Subject: [K12OSN] LTSP server with 3 NICs?

I booted up the client on the NIC that works, logged into the client window manager, opened a terminal, su'd and ran system-config-securitylevel-tui There were three interfaces listed: eth0, eth1, eth2 I marked the LTSP networks as trusted. I rebooted the server and the client and tested out the client's booting. It still successfully booted on the NIC which it did before. I switched it to the other NIC, and it got past where it froze before!! It now stops with the following error: mounting root filesystem:/opt/ltsp/i386 from: 192.168.3.254 mount: 192.168.3.254:/opt/ltsp/i386 failed, reason given by server: Permission denied mount: nfsmount failed: bad file descriptor mount: mounting 192. 168.3.254:/opt/ltsp/i386 on /newroot/nfsroot failed: invalid argument. ERROR! Failed to mount the root directory via NFS! Possible reasons include: 1 ) NFS services may not be running on the server 2 ) Workstation IP does not map to a hostname, either in /etc/hosts, or in DNS 3 ) Wrong address for NFS server in the DHCP config file 4 ) Wrong pathname for root directory in the DHCP config file Kernel panic - not syncing: Attempted to kill init!

You're now TFTP-booting, and this is GOOD. What you're now dealing with is an NFS permissions issue. Your 192.168.3.x's are still pointing to /opt/ltsp/i386, not /opt/ltsp/i386-3. Check out /etc/exports one more time. --TP _______________________________ Do you GNU ? Microsoft Free since 2003 --the ultimate antivirus protection!

SOLVED!!!! Message-ID: Hello, It's working!!! It's a sight of beauty... So here's what happened. I noticed that the error I posted about just now was talking about trying to mount a filesystem but it wasn't working. I also noticed it wasn't using the i386-3 directory when it should be. So I looked more closely at the DHCPD.conf file and found a mistake! The line was in the second scope: option root-path "192.168.3.254:/opt/ltsp/i386"; but it should have been: option root-path "192.168.3.254:/opt/ltsp/i386-3"; I got this idea from reading through the email archives related to the error's keywords and I found a posting by Jim McQuillan (Mr. Ltsp himself) ) Copy your lts.conf file from /opt/ltsp/i386/etc to /opt/ltsp-4.2/i386 2) Add "/opt/ltsp-4.2/i386" to your /etc/exports file 3) run 'exportfs -ra' to update the nfs daemon 4) Modify your dhcpd.conf file as follows: a) Change the 'filename' parameter to point to the new kernel, it should be '/lts/2.6.16.1-ltsp-2/pxelinux.0' for PXE booting and '/lts/vmlinuz-2.6.16.1-ltsp-2' for Etherboot booting b) Change the root-path entry to point to '/opt/ltsp-4.2/i386' 5) Restart dhcpd I realized it was an analogous situation so I did that exportfs -ra command, then hunted around in dhcpd for that root path and found it was wrong. Changed, restarted and they both boot!!!!! I must thank you all so very much. I would have given up a long time ago without everyone's help.

It seems to load all files by TFTP, but then I get the following messages: Red Hat nash version 6.0.52 starting mount: RPC: Authentication error; why = Failed (unspecified error) nfsmount: error mounting 192.168.1.103:/opt/ltsp/i386 on /sysroot as nfs: Bad file descriptor /setuproot: moving /dev failed: No such file or directory etc...... I interpret this to mean that the thin client is trying mount /opt/ltsp/i386 as /sysroot on the thin client. the IP of the server is correct. As suggested in a posting about another RPC-related problem: > /root#/usr/sbin/exportfs -v > /opt/ltsp (ro,async,wdelay,no_root_squash,no_subtree_check) I have tried rebooting the server, and even restarting rpcbind and nfs, with no luck. Help would be appreciated. -- ============================================ Brian Fristensky 971 Somerville Avenue Winnipeg MB R3T 1B4 CANADA bfristen at shaw.ca 204-261-3960 ============================================ From wtogami at redhat.com Sun Dec 28 09:33:50 2008 From: wtogami at redhat.com (Warren Togami) Date: Sun, 28 Dec 2008 04:33:50 -0500 Subject: [K12OSN] Re: K12Linux F10 Live media In-Reply-To: <4954B4BE.8010809@redhat.com> References: <494D1867.6010000@redhat.com> <4954B4BE.8010809@redhat.com> Message-ID: <495747FE.2030800@redhat.com> Warren Togami wrote: > http://alt.fedoraproject.org/pub/alt/ltsp/k12linux/f10/untested2/ > Updated images for i386 and x86_64... completely untested at this point. > Feedback is needed.

It seems to work fine, but I noticed an error in Peter's k12linux-quickstart-guide. https://bugzilla.redhat.com/show_bug.cgi?id=464430 I think we are ready for a F10 Live Server release only after the contents of the documentation are reviewed/improved.

It turns out my problem was already reported, but since I didn't know which video chipset my clients have, I didn't know what to search for. https://bugs.launchpad.net/ubuntu/+source/module-init-tools/+bug/208137 So, if your thin clients have VIA CLE266 chipsets--like the Devon IT NTAVO 6020P's--add vt8623fb to the blacklist as explained in the bug report.

Or are you using Rescue Mode? If you can log in directly as root, then can you take a look at the permissions for the user home directories? Also, take a look at /var/log/secure and /var/log/messages to see if you're getting any indication as to what might be going haywire here. --TP From wtogami at redhat.com Mon Dec 29 19:22:16 2008 From: wtogami at redhat.com (Warren Togami) Date: Mon, 29 Dec 2008 14:22:16 -0500 Subject: [K12OSN] RE: K12Linux F10 Live media In-Reply-To: <62432006F5965C42BAEC4EA29286EE0507B4C33B1A@EX-CMS01.westat.com> References: <62432006F5965C42BAEC4EA29286EE0507B4C33B1A@EX-CMS01.westat.com> Message-ID: <49592368.2070907@redhat.com> Henry Hartley wrote: > Warren Togami wrote: >>> Warren Togami wrote: >>>> http://alt.fedoraproject.org/pub/alt/ltsp/k12linux/f10/untested2/ >>>> Updated images for i386 and x86_64... completely untested at this >>>> point.
