Hi, I'using LTPS on debian. After Kernel-Update Clients fail to boot. On Client-Console I see an messages like
02:52
IP-Config: eth0 Complete ...
02:52
address: ...
02:52
gateway: ...
02:52
rootserver: ...
02:52
filename :
02:52
Error: Connect: Connection refused
02:52
mount: mounting aufs on /root failed: No such device.
02:52
What is going wrong here?

<X-TaZ>
elmar1969, it seems wou're having an issue with your tftp
02:58
Is it running ?
02:59
<elmar1969>
The dir /var/lib/tftpboot/ltsp/i386 dore contain config-2.6.26-2-486 initrd.img@ initrd.img-2.6.26-2-486 nbi.img@ nbi.img-2.6.26-2-486 pxelinux.0* pxelinux.cfg/ System.map-2.6.26-2-486 vmlinuz@ vmlinuz-2.6.26-2-486
02:59
Is there anything missing?
03:00
<X-TaZ>
try a "netstat -lataupe" and try to see if your server is listening on tftp port
03:01
<elmar1969>
It is listening via inetd - the client does load kernel via tftp - the tftp-server cannot be completely off
03:02
<X-TaZ>
Well, I don't know how to help you :)
03:03
I don't know why your nbi.img have an @. Mine don't have
03:05
In my dhcpd.conf i can see the folowing :
03:05
option root-path "/opt/ltsp/i386";
03:05
if substring( option vendor-class-identifier,0,9)="PXEClient"{
03:05
filename "/ltsp/i386/pxelinux.0";
03:05
} else{
03:05
filename "/ltsp/i386/nbi.img";
03:05
}
03:05
}
03:06
So it loads nbi.img and not nbi.imb@ , elmar1969
03:07
<elmar1969>
the @-sign is shown as it is an symbolic link
03:07
I'm usins dnsmasq but this is unchanged.
03:08
<alkisg>
elmar1969: do you have another dhcp server running, e.g. a router?
03:09
<elmar1969>
I'm shure it is switched off - else it would raise chaos. In any case it would never send out boot information.
03:10
<alkisg>
elmar1969: if it's on, it would behave like the error you see
03:11
I.e. your normal dhcp server would give the initial ip address, and the router the second ip address (in the initramfs/ipconfig), so it would fail to contact the nbd-server
03:15
<elmar1969>
Thr router config page shows DHCP off. How can I search for DHCP-Server on network?
03:16
<alkisg>
elmar1969: try this: sudo /opt/ltsp/i386/usr/lib/klibc/bin/ipconfig -n eth0
03:16
-n means not to actually set the ip
03:16
(that's from the server)
03:18
elmar1969: or, see the output from the client: "(10:51:09 πμ) elmar1969: rootserver: ..." => it should be your ltsp server
03:20
<elmar1969>
Rootserver is my DHCP server, rootpath is pointing to my ltsp-server
03:20
<alkisg>
Hm? Are they different?
03:22
<manu_ubu>
problem with tftp or inetd ?
03:23
<elmar1969>
alkisg: The are different, the LTSP-Machine is not running 7/24, the DHCP-server is 7/24
03:24
<alkisg>
elmar1969: Where's your tftp server?
03:24
<elmar1969>
manu_ubu: how can I make tftp-deamon be more verbose? I cannot see any logs for tftp traffic
03:25
The tftp-server is on LTSP machine
03:25
<alkisg>
elmar1969: so make rootserver = ltsp server in dnsmasq.conf
03:25intelliant_ has quit IRC
03:26
<elmar1969>
alkisg: what config-option does that in dnsmasq?
03:27
<manu_ubu>
if you want test tftp use on terminal tftp address-IP-server 69 -c get /ltsp/i386/pxelinux.0 /tmp/pxelinux.0
03:28
<alkisg>
elmar1969: what setting do you have for next-server in dnsmasq.conf ?
03:29
<elmar1969>
manu_ubu: I can get that file by tftp from my workstation
03:30
there is no next-server option in dnsmasq.conf
03:31
<alkisg>
elmar1969: set one to point to your ltsp server
03:32
<manu_ubu>
ok your tftp run
03:33
<alkisg>
elmar1969: I don't really know if that's what it's called in dnsmasq.conf, next-server is dhcp3-server "terminology"...
03:34
It's the ip of the tftp server....
03:37
elmar1969: if that doesn't do it, then you may need an nfsroot=<server-ip>:/opt/ltsp/i386 kernel parameter in pxelinux.cfg/default, but I'm not familiar with nfs, so I can't tell you the exact line

Still need more ideas to proceed: my LTSP client does start with initramfs prompt only after kernel-update. Waht can help there?
04:38
<laga>
looking at any error messages you may be getting
04:43hanthana has quit IRC

<manu_ubu>
elmar1969: you have busy-box as shell on your client ?
04:44
<elmar1969>
yes
04:44hanthana has joined #ltsp
04:46
<manu_ubu>
ok have you again rebuild the kernel in the chroot : update-initramfs -u and update with ltsp-update-kernel ?
04:50jaime_david has joined #ltsp
04:50jaime_david has left #ltsp
04:51
<elmar1969>
done again (the 'update-initramfs -u' whithin chroot, 'ltsp-update-kernel' outside) - no difference
04:52
<manu_ubu>
ltsp version ?
04:54
<elmar1969>
Client and server are at 5.1.69 (Debian testing)
04:55
Should I change that to 5.1.73 (Debian-unstable)?
05:00
Update to 5.1.73 did not solve problem

Would it help to send an screenshot of last messages? Where to place PNG file?
05:04
<manu_ubu>
have you test inetd running ?
05:05
<elmar1969>
What is "test inetd"
05:05
<manu_ubu>
ps -A |grep inetd
05:06nubae has quit IRC
05:06nubae has joined #ltsp
05:07
<elmar1969>
On my ltsp server it displays " 7712 ? 00:00:00 inetd" on busybox-client it does show nothing.
05:13
<manu_ubu>
if tftp and inetd run perhaps have you a problem this kernel ?? anybody have a idea ?
05:16
<elmar1969>
form busybox I do have trouble on manually mounting NFS rootdir: module "nfs" seems not to be loaded automatically, "mount IP:/opt/ltfs/i386 /tmp/mnt" does report "no such file or directory" while "/tmp/mnt" does exist
05:31
The problem seems to be in the way ltsp does handle kernels, I did try several debian-kernel packages with same effect
05:34
Why does ltsp copy the kernel-dir to an separate TFTP-dir?
05:37
setting initramfs-tools-options to nfs-boot did also not help

:-) Sorry that was my mobile connection on the bus
13:11
which is 3g/gprs and as one can see it jumps quite a lot

still it works, I can be connected constantly and work while moving around

How can I get a list of the users that belong to a group?
13:15
<treyh>
*thinks back to his freebsd days*
13:15
alkisg: sec I'll look it up
13:15
<epsas>
depends
13:15
if you are using files for your groups
13:16
you can just grep the groupname in /etc/groups
13:16
<stgraber>
alkisg: getent group <group name>
13:16
<treyh>
grep groupname /etc/groups
13:16
damn it lol you guys beat me
13:16
<stgraber>
the getent will also work with LDAP though ;)
13:16
<epsas>
stgraber is using science
13:17
<alkisg>
I have this: getent group fuse|cut -d: -f4|tr , ' '
13:17
And I was looking for a better way, because it doesn't tell me that "alkisg" user belongs to the "alkisg" group... :(
13:17
<stgraber>
alkisg: not sure there
13:17
*** keyboard ...
13:18
not sure there's an easy way to get the list including the users for which the group is their primary group
13:18
<alkisg>
Ah... I was afraid of that :(
13:18
Thank you guys
13:18
<Gadi>
alkisg: use "group"
13:19
<alkisg>
Gadi, ? group => command not found...
13:19
<Gadi>
oops - groups
13:19
<stgraber>
groups work as id
13:19
<alkisg>
Gadi: that's the opposite question :)
13:19
<Gadi>
oh
13:19
<stgraber>
as in it'll give you the list of groups for a user
13:20
not the list of users for a group

i really need to learn more erlang..
13:22
enough to fix the silly transport to store nickserv credentials..
13:22
so it doesn't cause me to nickchange so often on freenode
13:25
<alkisg>
Ah, there's a utility for what I was looking for, called "members". So I guess there's no trivial way for that.

"alkisg" pasted "add-keyboard-applet" (148 lines) at http://pastebot.ltsp.org/348
14:52
<alkisg>
I've just finished a script that adds gnome-keyboard-applet to the top panel for ALL users. beta testers are welcome :)
14:52
It should work on Ubuntu 8.04, 8.10 and 9.04. With sudo sh add-keyboard-applet it changes the defaults for new users, and with sh add-keyboard-applet it adds it to the panel of the current user.
14:52
Well, question: where is a good init script to put it so that it gets executed when the users log on? In /etc/profile.d ?

Too darned busy.
20:23
However!
20:24
I did squash a bug in ldm the other day.
20:24
which got me to thinking.
20:24
Here was the problem
20:24
I was getting the hanging up on login thingy.
20:24
setting the "NOBLOCK" flag didn't work for me, for some reason.
20:25
sometime after login, the ldm ssh login that idles on the /bin/sh - was getting more input.
20:26
i.e. there was some kind of data on the shell output. don't know what.
20:26
Solution was to spawn a "reader" thread, that after a successful login, sat and idled in a select() statement on the stdout on the /bin/sh -, and simply discarded input.
20:27
worked like a charm
20:27
so.
20:27
one of the things I *never* liked about my re-write of LDM was that it's very linear. There's little to no event handling.
20:27
do the chat
20:27
get the login
20:27
spawn the X
20:27
boom
20:28
if anything out of the ordinary happens, things "don't work so well"
20:28
sooo
20:28
I was thinking how to re-do ldm into a full glib mainline()
20:28
add io_watchers for each of the communications channels
20:28
proper signal handling, etc.

Hi I have a internetshop that is running ltsp-5 its ubuntu 9.04, can I use skype on my setup?
20:40
specially video conference
20:43
<vagrantc>
sbalneav: i'm sure glad i don't have to think about all that stuff :)
20:44
sbalneav: sounds like my whole feeling of "everything is stabalizing" is about to take another one of those hard left turns.
20:44
for the better, i'm sure :)
20:48
<sbalneav>
Well, if we work on anything, it'll be ldm3, with a completely separate branch.
20:50
<vagrantc>
wheee!
21:01
ltsp, ldm and ltspfs are in debian sid (unstable) are fully compatible with debian lenny (stable)! yay. saves the hassle of backporting. :)
21:04
<sbalneav>
awesom
21:06
<vagrantc>
recent improvements in unstable actually do a better job of not bloating versioned dependencies, so many of the packages actually (claim) to be compatible with older versions than what's even in lenny. some might even be etch compatible.

My instructor was Mr. Langley, and he taught me to sing a song. If you'd like to hear it I can
