Seriously, I would consider DRBL: http://drbl.sourceforge.net/ From william at fragakis.com Fri Oct 1 17:28:40 2010 From: william at fragakis.com (William Fragakis) Date: Fri, 01 Oct 2010 13:28:40 -0400 Subject: [K12OSN] Recommended Gigabit Network card? In-Reply-To: References: Message-ID: <1285954120.12534.173.camel@localhost.localdomain> We used to serve 10 users on boxes just like this. Now it's a client... (I'm feeling even older.) In my experience, gigabit all the way to the client does help video performance when using highly network intensive programs (ie Flash on Youtube). The onboard Intel is quite adequate (you can run compiz on the clients). If you are squeezed for cash, you could ebay the ATIs and use the onboard. OTOH, having DVI output probably gives you more options in the future when 22" LCDs are $100. DRBL is a great suggestion. There's a LiveCD that works quite well if you want to give it a quick spin. Glad you got a good surprise when you opened your donations. Mostly, I'd just find dust bunnies that would make me sneeze.

KDE 4, localapps and sound are a minimum for me, as is a recent kernel so F12/LTSP 5 is pretty much my baseline. I am quite happy with F12 K12Linux but of course F12 will be EOL in a couple of months. I plan on upgrading to F13 to buy me another 6 months, but after that I too would like a long term supported system that meets my requirements. That sounds exactly like CentOS 6 + LTSP 5. I have a small amount of packaging experience and like others would be willing to help package. The bigger issue is probably any other development related integration issues. Is anyone with that kind of skillset willing/able to work on this? Work could start now on RHEL6 beta, which is an open (free) release.

We're on LTSP 5 and have the following two nagging problems: -- USB drives seem to work for my account but not for student accounts. Students are all in one large group, while the administrators are in a "staff" group. I am sure this is a permission issue, but I can't figure out where or what to look for. I can tell from the messages on the client machines that the drive is recognized, but the server doesn't seem to see it unless *I* am the one logged into the client that is mounting it. Does anyone have a clue what to look for? I'm sure this is simple... -- The screen saver timeout is set to 5 minutes after which it locks the screen. This drives the students and teachers crazy. Is there a way to set this centrally? I've tried gconf-editor but it only applied the settings to the account I was working in.

Let's try this again. Earlier this fall I updated my server from CentOS 5.4 to CentOS 5.5. Immediately my thin clients would not recognize USB memory sticks. (The thin clients are DevonIT 6030, about 3 years old, and dirt reliable.) Following several bits of advice, I got the units working again by: 1. Install fuse and fuse-libs 2. Cause all users to be joined to the fuse group in /etc/group 3. Remove the modprobe for ehci_hcd in /opt/ltsp/i386/etc/rc.sysinit and /opt/ltsp/i386/etc/rc.usb 4. Reboot the thin client Bingo, all started working again.

So I am in the process of testing out a new installation of Edubuntu and I noticed that FreeNX seems to be *much* slower on Ubuntu than on Fedora. Here's the setup: - Fedora 10 server (older hardware) - Edubuntu 10.10 server (ironically newer hardware) Both these servers are in the same rack, plugged into the same switch going to the same router out to the Internet. I'm connecting to both of them using the NoMachine NX client from the same computer at home. Configuration at the client end is identical (resolution, LAN settings, etc.) I can easily see the screen refreshing during the Edubuntu session while the Fedora session is much more smooth. Is this something anyone else has noticed? Or are there specific settings on the servers that I would need to change to maximize performance?

The real issue with wireless LTSP is the bandwidth -- or lack of it. It might be usable for a client or two but I suspect it would quickly fall apart as the number of clients grew. The next issue is finding a way to get the wireless to run something like PXE. I kinda doubt that works. I have encountered the same wireless issue when trying to come up with a mobile thin client that could work across the internet. I decided to use a minimal fat client (installed from a live CD) on the laptop that allowed the normal NetworkManager tools to find and connect to APs as well as firing up a VPN tunnel to the terminal server, then ran an NX client. It has the side benefit of being a useful fat laptop in case the user doesn't have internet access. Unfortunately I haven't been able to get freeNX to work on Fedora 12 :( Anyway, if you find a solution please post it.

Any references to 'metacity failed"? Could you expound on what you mean by "loads on the client fine",but not automatically on logon?... Is there any difference if you change the logon session from default Gnome to KDE,for example? Does root see the same behaviour? No minimize,max,etc? On a client ,in a terminal when doing a 'ps aux|grep metacity' do you see something like: username 8041 0.1 0.2 16392 7380 ?

So we have to look at some other ways to boot the minimal OS. So I decided to use either a CDRom or USB pendrive to make an equivalent setup like PXE." By my definition CDROM/USB drive != diskless. The other issue I see with this is it can really only work in a single environment. If _any_ user intervention is required things fall apart. Examples of user intervention include free wifi variants that make the user agree to conditions on a web site before connecting, any network with wireless security enabled, and any non-broadcast SSID networks. In my experience that accounts for the bulk of public wireless! For me yet another requirement is VPN capabilities. If I ever get NX working I will post my results with that over wireless.

The reality of wireless b/g is that only 3 non-overlapping channels are usable in the same area, so at best you could get 3 APs running at once. Either that or move to wireless n but that still has a maximum of 4 MIMO streams -- albeit at much higher bandwidths.

Are you having trouble with NX in general or just trying to boot directly into a client? It's low bandwidth requirement does make it seem like the best approach for using many wifi clients at once. -- Les Mikesell lesmikesell at gmail.com From william at fragakis.com Mon Oct 25 16:31:15 2010 From: william at fragakis.com (William Fragakis) Date: Mon, 25 Oct 2010 12:31:15 -0400 Subject: [K12OSN] K12OSN Digest, Vol 80, Issue 15 In-Reply-To: References: Message-ID: <1288024275.29740.843.camel@c-69-180-1-66.hsd1.ga.comcast.net> Jeff, You pretty much covered what I was going to write about - seeing that a handful of clients saturate a wired 10/100 link, under current technology, wireless would present more problems than it would solve. Someone else referenced an LTSP wireless solution which isn't really ltsp so much as having a boot image on some sort of attached storage, e.g. flash drive. While it would be relatively easy to set up a spin of your favorite distro, say, with nm-applet configured to automagically connect to your wireless, you are moving away from the true TC. You are adding additional points of failure (bad/broken flash drive, need for updating the image on the drive) not to mention that in a school environment, the flash drives might learn to "walk" - go missing. On the freenx, are you using freenx as a client or nomachine's version as the client? I use the nomachine version on F13 with no problem with the freenx server. I believe the freenx client on late versions of Fedora have been problematic. regards, William On Mon, 2010-10-25 at 12:00 -0400, k12osn-request at redhat.com wrote: > Message: 2 > Date: Sun, 24 Oct 2010 19:54:18 -0400 > From: Jeff Siddall > To: "Support list for open source software in schools." > > Subject: Re: [K12OSN] Wireless - TC boot status > Message-ID: <4CC4C72A.9040500 at siddall.name> > Content-Type: text/plain; charset=ISO-8859-1 > > On 10/24/2010 10:10 AM, Barry Cisna wrote: > > Hello All, > > > > Been out of the loop for a while now,in regards to wireless boot > > possibilities for TC's.

I was initially having problems because I had enabled AllowGroups for sshd. I never got that combination working, and spent far too long trying. The problem was that When I added nx to an allowed group sshd would remove it and block the access on the next login attempt. Denyhosts also tried it's best to prevent things from working. Good grief. Unfortunately even with all the extra security turned off I still cannot get it to work. I gave up for the night before I got too far into troubleshooting the latest problems.

If you are using freenx on the server side, remember that it defaults to making a unique key per install, so you have to paste the key from the server's client.id_dsa.key into the client key config screen. Also, the first connection happens as the nx user so your login/password can be passed over the encrypted connection for the real user. -- Les Mikesell lesmikesell at gmail.com From Steven at SimplyCircus.com Mon Oct 25 21:59:42 2010 From: Steven at SimplyCircus.com (Steven Santos) Date: Mon, 25 Oct 2010 17:59:42 -0400 Subject: [K12OSN] K12OSN Digest, Vol 80, Issue 15 In-Reply-To: <1288024275.29740.843.camel@c-69-180-1-66.hsd1.ga.comcast.net> References: <1288024275.29740.843.camel@c-69-180-1-66.hsd1.ga.comcast.net> Message-ID: >From reading the project page, it looks like what we did with non-pxe/etherboot machines way back when (anyone remember the boot floppy?).

I am interested in setting up local apps on Edubuntu. I understand that when I activate the local apps option, one thing I must do is set up the server so it transmits the Internet through to the thin clients (I am running a two-NIC server setup). My question is, if someone unplugs the thin client network cable from the wall, and plugs in their own laptop, will then then be given an IP address by the server and given Internet/network access? If so, is there a way to stop this?

This will only work if there is no router between the server and clients. Anybody able to spoof the MAC from a thin client would still have access, however setting this up shouldn't take too long and should serve the purpose of discouraging casual misuse of the thin client network cables.

Probably what you really want is a USB/flash boot into something running the NX client with a painless way to keep the boot image up to date - like being able to run from ramdisk while overwriting the boot image if a change is needed, or having enough flash for two copies and a way to copy the new one in and toggle which is used for the next boot.

Something like this with a CF/SD card can easily be mounted to a motherboard or inside a machine to allow such booting: http://www.addonics.com/products/flash_memory_reader/ad44midecf.asp http://www.addonics.com/products/flash_memory_reader/adidesd.asp One could also mount a USB key inside the machine.

Not as painless as making something auto-update but still fairly easy and adaptable to about any way you can make a machine boot (a wired drbl server probably being the most straightforward). -- Les Mikesell lesmikesell at gmail.com From rowens at ptd.net Wed Oct 27 23:00:33 2010 From: rowens at ptd.net (Rob Owens) Date: Wed, 27 Oct 2010 19:00:33 -0400 Subject: [K12OSN] Local apps question In-Reply-To: <506CA108-7F20-40D1-819B-422162628D0E@thealmquists.net> References: <506CA108-7F20-40D1-819B-422162628D0E@thealmquists.net> Message-ID: <20101027230033.GA32617@aurora.owens.net> On Tue, Oct 26, 2010 at 06:37:31PM -0500, Burke Almquist wrote: > You could set up your dhcp server to only give out addresses to known clients by mac address, but I guess technically I guess they could still use a static ip, netmask, and gateway. > You'd have to set up a non-transparent proxy if you want to block internet access for PCs. > "man dhcpd.conf" and look for "deny unknown-clients" to learn how to do this. -Rob From reb at taco.com Thu Oct 28 19:40:10 2010 From: reb at taco.com (Phydeaux) Date: Thu, 28 Oct 2010 15:40:10 -0400 Subject: [K12OSN] LTSP - No clients can connect! Message-ID: Argh! We're running LTSP on Fedora 13. We started having problems with some clients not being able to connect and realized we had errors in our DHCP config. At the same time, we had some kernel failures on the server causing applications to not work. We rebooted and everything seemed fine so we applied the latest Fedora 13 updates, which included a new glibc and kernel. Clients could connect after this, but still only about 50% of the time. The other 50% they failed. Now we're in a state where no new client connections ever succeed. It appears that things are getting stuck at the time the root filesystem is mounted on the clients. We tried to fix the DHCP configuration issues (we were assigning static IPs from the dynamic pool) and things went downhill. The IPs are assigned fine and the boot goes smoothly until just after the video mode changes. At that point, we see this: ----------------------------- scsi6 : pata_atiixp scsi7 : pata_atiixp ata7: PATA max UDMA/100 cmd 0x1f0 ctl 0x3f6 bmdma 0xfa00 irq 14 ata8: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0xfa08 irq 15 r8169 Gigabit Ethernet Driver 2.3LK-NAPI loaded r8169 0000:02:00/0: PCI INT A -> GSI 18 (level, low) -> IRQ 18 eth0 RTL8168c/8111c at 0xf80fc000, 6c:f0:49:7a:96:ac, XID 1c4000c0 IRQ 26 r8169 etho: link down r8169 etho: link down No root device found No root device found Boot has failed, sleeping forever. ----------------------------- We tried rebuilding the client images. The i386 clients are and were using Fedora 12. The x86_64 clients are and were using Fedora 13. We tried going back to older kernels for each of these. There was no change that could be identified as fixing things, but at some point one or two clients managed to boot. Then, no more. Something simple is messed up, but we're not sure what. We've looked at... - ltsp dhcpd.conf - lts.conf -- it's unchanged - NFS daemon is running - iptables -- was running, we turned it off - Lots of other stuff. We believe the static IP assignments are working as we see no more warning messages in the log. The clients are getting both a vmlinuz.ltsp and the initial ramdisk just fine. Things look fine on the server, but no clients connect. The network driver clearly works long enough to download these items, but then we see the "link down" message. We were hesitant to reboot, as some of the clients were still working. After doing so, the ones that were up but logged out were still able to log in.

If so is there more than one NIC in the client? If not then something is seriously wrong if you are getting "link down" messages. Either the kernel is lying and the link really is up, or the kernel is telling the truth and your network switch is dropping the network connection for some reason. Can you log into the network switch and see what is going on on the ports for clients that can't connect?

Fire up Wireshark on the same linux laptop and filter down Wireshark to an ip address of ONE client ip address you have statically assigned in dhcp.conf.

I would try one with an "external" (ex: USB) boot device and make sure you are happy with it before spending too much effort making a BIOS boot version.

I am sure there is some behinds the scenes quirks that may be slightly different between versioning numbers, and actual OS's etc. I am probably wrong but I think in your tcp returns of nmap you should at least have port 6001 = X11 and , 7100 = font-service in order for TC's to negotiate as expected,although you said some clients are A-OK?...Your nmap returns are not showing these two ports listening? What do see when you run on the server 'tail -f /var/log/messages' and boot a thin cleint ? Do you have SELinux disabled as well? Keep us posted!

Well, we've fixed things -- and nmap is still not showing those ports open. > What do see when you run on the server 'tail -f /var/log/messages' and > boot a thin cleint ? > Do you have SELinux disabled as well? We're running SELinux... We did figure out what was wrong. We have all of the clients connected via 1GB Ethernet on a private LTSP lan with its own 1GB switch. For the "outside" network that the LTSP server connects to the Internet over, that hosts our network printers, and that the office uses, we have a 10/100 switch. While exhausting all the options we could think of to fix the software, I noticed that some clients would complain about the network not being available and not getting IP addresses assigned by DHCP. Changes in the DHCP issue seemed to be independent of any of the software changes we were making. On a hunch, I disconnected everything from the 10/100 switch and moved all of the connections from the 1GB switch to it. After further testing, we also moved the server's LTSP connection to a spare 10/100 Ethernet port we had available. Lo and behold, everything worked. A quick trip out to some local stores netted us a replacement 1GB network card and a replacement switch. At least we ended up with the clients at FC13. We also got the USB problems on the client partially solved. The clients seem to be able to use USB flash drives just fine when in 32 bit mode. They still do not work on x86_64 clients. For now we're just having everything boot as a 32 bit client. Nobody except the sysadmins knows or cares about that distinction. Thanks for the advice! reb
