<tim>
hello all, I'm an 8th grade teacher and hoping this is the right place to get help.
01:48
I know you can set up thin clients that log onto the edubuntu server -- is there anyway you can set up a workstation (where all programs run off the local harddrive) but all log-ins go to the server and all user data is saved on the server? All support pages I'm finding talk about thin clients -- I want clients with harddrives but that log-on to the server
01:49
<johnny>

07:49
2. localdevices does not work , i have correctly confifured lts.conf( i thing :) )

09:37* nonix4 ponders why jaunty ltsp client built inside KVM doesn't even try to contact the NBD while one built outside any VM works properly...
09:41
<alkisg>
ports problem?
09:41
<nonix4>
tcpdump showing zero traffic...
09:42
<alkisg>
How does it die? error messages?
09:43
...and, is the ltsp server in the kvm, or a client?
09:47otavio has joined #ltsp
09:50
<nonix4>
What works is ltsp server & client on hw, server in kvm with client on either doesn't. ipconfig: eth0: SIOCGIFINDEX: No such device ... /init: .: line 1: can't open /tmp/net-eth0.conf when client is in vm, IP-Config: no response after 60 secs - giving up when client is hw
10:11
<shamael>
strange, I have an ltsp server inside kvm working
10:11
not working too well but clients can boot
10:20japerry has quit IRC
10:28
<alkisg>
nonix4: that error says that there are no drivers in the initramfs for the particular ethernet card that the kvm emulates
10:29
nonix4: the second error with the client in hw could possibly mean that there are port problems. Does kvm run under root priviledges, so that it has access to ports < 1024? (=dhcp server)
10:33
<nonix4>
well dhcpd obviously works as it gets that far in the boot... and nbd is at port 2000 anyway.
10:36pmatulis_ has joined #ltsp
10:36
<alkisg>
Right... well, ipconfig asks for a dhcp lease before the nbd mounting happens, so it seems like a dhcp problem.
10:36
<nonix4>
maybe it asks that while network card isn't available for reason or another? (race condition?)
10:37
<alkisg>
You could tell ipconfig to reuse the same ip that was sent in the pxe stage by putting IPAPPEND 3 in pxelinux.cfg/default, but I don't know if that's a proper solution to your problem

Lns: we are working with x64 jaunty and our chroots are X386
10:50
if you are here :)
10:56
<nonix4>
alkisg: hmm, thanks... IPAPPEND 3 fixes the server-in-vm, client-on-hw problem. Now to get purely virtual stuff working...
10:56
<alkisg>
nonix4: what nic does your kvm emulate?
10:57
E.g. lspci -nn on the virtual ltsp server
10:58
<nonix4>
8139 on the virtual ltsp server
11:00
<alkisg>
Urm, if the client also uses the same virtual nic, it shouldn't show "SIOCGIFINDEX: No such device"... :-/
11:00
<nonix4>
well actually two on ltsp server, "Qumranet, Inc. Virtio network device" and that Realtek thing.
11:01
<alkisg>
Can you see which one does the virtual client have?
11:03nivelpp has joined #ltsp
11:05
<alkisg>
(or better yet, change it to realtek?)
11:13
<nivelpp>
alkisg: can you help me with two last things :) ? everithing is going OK but :
11:13
1.sound does not work , it work in first time login after servver restart
11:13
2.localdevices does not work
11:13
i was following manuals but , no succes
11:14
<alkisg>
nivelpp: could you remind me your setup? distro/version/localapps or not etc...
11:15
<nonix4>
alkisg: ok, so virtio network driver is missing from jaunty ltsp initrd... changed it to use e1000 since that is closer to actual hardware in use here :)
11:16
<alkisg>
nonix4: if you're gonna use the IPAPPEND 3 trick, you'll also need to make a symlink to lts.conf because the clients won't be able to find it
11:17
ln -s ltsp/i386/lts.conf /var/lib/tftpboot/lts.conf
11:17vagrantc has joined #ltsp
11:18
<nivelpp>
alkisg: ubuntu 9.04 i386 , clients i386
11:19
<alkisg>
nivelpp: "localdevices do not work" ===> are your users in the fuse group?
11:19
<nivelpp>
it doesn not matter that localapps are enabled or not , problem is the same
11:21
alkisg: yes i have tested it with one user and he is in fuse
11:21
group
11:21
<alkisg>
nivelpp: and if you plug in a usb stick or a cd, it doesn't work?
11:22
<nivelpp>
alkisg: yes, exactly , when i log in to client command line i can see devices in /dev/
11:24vagrantc has quit IRC
11:24
<alkisg>
nivelpp: well, the only other reason I've seen localapps fail was when badly formatted sticks were used
11:25
Did you try with a cd? If it doesn't work with a cd, you'll need someone more experienced than me to guide you through the udev logs...
11:25
<nivelpp>
ok , i will try it
11:25
alkisg: and what abou sound ?
11:26
<alkisg>
I've heard of pulse crashing, and I think it logs some things to the local syslog, but I don't know anything more about sound. It always works out of the box for me.
11:28
<nivelpp>
alkisg: ok thanks , i will try to reinstall my system maybe i have configured sometihng wronk and i dont now what
