<friendly_fire>
are clients supposed to be chrooted to /opt/ltsp/i386 by default, or do I need to do that with pam?

<johnny>
friendly_fire , are you having a problem?
00:36
the client install can be modified by using the chroot, but the clients are *not* chrooted there
00:36
<friendly_fire>
oh
00:36
i think i get it then
00:36
i was expecting them to be on /home in that, and not the real /home
00:36
<johnny>
the clients have a copy of /opt/ltsp/i386
00:36
that they use to boot from
00:37
either via nfs by mounting it
00:37
or by default ubuntu via nbd
00:37
which actually serves a squashfs image
00:37
so they are getting served animage generated by the chroot (thus ltsp-update-image)
00:38
<friendly_fire>
what i'm having is i boot a client, i make a file on the desktop, and that file is placed in /home/user/Desktop
00:38
<johnny>
on the server
00:38
?
00:38
<friendly_fire>
and not in /opt/ltsp/i386/home/...
00:38
is that the idea?
00:38
yes, on the server
00:38
<johnny>
yes
00:38
that's how it is
00:38
<friendly_fire>
ok, if that's how it is that's fine. I was thinking it would all be in /opt
00:38
<johnny>
:)
00:38
well there ya go :)
00:39
<friendly_fire>
thanks a lot for that help, really clears some stuff up
00:39
<johnny>
feel free to ask anything else..
00:39
about ltsp that is :)
00:39
<friendly_fire>
will do, thanks

cyberorg: that's a mkdst bug
09:38
cyberorg: fix is already committed, but I need to push the new mkdst
09:39
<cyberorg>
warren, no, i don't use mkdst
09:40
<warren>
cyberorg: you should be using mkdst to generate the tarball at least.
09:40
<cyberorg>
we should be manually doing touch Changelog, it should be present already or may be ./autogen.sh should create it
09:40
*shouldn't
09:40
<warren>
it is a stupid autoconf bug that it wants a specific filename and fails without it
09:41
but no, I am not adding an empty ChangeLog to the source repo
09:42
<cyberorg>
start adding things in Changelog, so packagers know what changed
09:42
<warren>
no
09:42
we decided for that package that ChangeLog is generated by mkdst directly from the bzr log
09:43
mkdst tar is the official way to create tarballs from the bzr tree.
09:43
LTSP upstream official
09:45
mkdst tar --from-tag=0.5.2 in this case
09:45
<cyberorg>
ok, hopefully now we will see upstream release tarballs

<zeltron>
Hi !
11:17
Everybody' sleeping or can I ask a question ?
11:18
<nobios>
ask it
11:19
<zeltron>
Thanks. I'm trying to make ltsp5 work with Debian Etch
11:19
I can't boot on the nbi.img
11:19
It's loaded on the thin client, but when it tries to boot,
11:20
I got a message like : it isn't initrd (bad magic number)
11:20
and then the client reboots
11:21
<klausade>
zeltron: don't ask to ask, just ask. upload errormessages (might be something in syslog) to some paste-service
11:21
<zeltron>
During ltsp-build-client, I got a message (when installing linux kernel 2..6.18-486) like this :
11:23
Hmmm ! package shipped with a symbolic link to sources, but not found, therefor removing source directory
11:23
(it's not the exact message, just what I kept in memory)
11:24
Klausade : I didn't know if the channel was working on week end ;-)
11:24rat has joined #ltsp
11:24
<rat>
i need to boot from my hard disk
11:24
pls help me with procedure
11:25
anybody here
11:26
<zeltron>
Can't upload errormessages, I'm home, and the server is shut down at work
11:27
<rat>
no i jst want like have hard disk in my client so i want to put the image of boot disk in hard disk
11:27
so it initializes the network
11:29
<klausade>
zeltron: hehe, not working in the weekend .... That would be the day.
11:29
<zeltron>
I already tried a lot of issues, I made it work with Ubuntu, search for a long time on the net, but found no answer
11:30
Klausade : I'm not working on the week end, but though, I'm on the channel trying to find a solution ;-)
11:31
In fact, the only solution I see is trying to get an nbi.img from a server that works under Debian Etch
11:32
or someone who could explain to me how is build this file, then I can try to build it by myself and see if it works
11:32
<vagrantc>
zeltron: it would be most helpful if you could ask the questions while you have access to your server and thin-clients
11:33Q-FUNK has joined #ltsp
11:34
<zeltron>
vagrantc : Yes, I know, but when I posted on the channel this week, someone said : this is a problem for vagrantc,
11:34
Trying to connect today and I saw you were here, so I hoped ...
11:36
But maybe we could take a rendez vous on this channel for last week and try to resolv this problem when I'm in front of the machine ?
11:38
<vagrantc>
i'd be glad to help, it's just nearly impossible to help without having access to the machines
11:40
<zeltron>
vagrantc : it's ok. When do you think we can meet here next week ? (last week, everytime I was connected, you were not)
11:40
<vagrantc>
zeltron: though, if you're using a recent version of etherboot everywhere, it probably supports PXE, and the simplest option would be to point dhcpd.conf's filename to just load pxelinux.0
11:41
<zeltron>
My dhcp server propose the choice between pxelinux and nbi, but thinclients always "chooses" nbi
11:42
(lines : if vendor.... pxe else nbi)
11:42
<vagrantc>
yes, you could try hard-coding it to use pxelinux
11:43
<zeltron>
I'm not a "pro" with thin clients, it's my first try... I'm not sure I've understood everything about this
11:43Subhodip has quit IRC
11:44
<vagrantc>
none of us understand everything... at least the people being honest
11:44MacIver has joined #ltsp
11:44
<zeltron>
My clients seem (for what I can understand) to boot with etherboot
11:45
<vagrantc>
yes, and recent versions of etherboot can pretend to be PXE clients.
11:45
so try feeding them the stuff for PXE.
11:45
<zeltron>
I already tried to force client boot on pxelinux, but it didn't work (don't remember the message, but I noted it at work)
11:45
<vagrantc>
ok.
11:46
did the systems come with etherboot pre-installed?
11:47
or could you try with a boot floppy or boot CD?
11:47
!bootfloppy
11:47
<ltspbot>
vagrantc: "bootfloppy" is http://etherboot.anadex.de or ftp://k12linux.mesd.k12.or.us/pub/K12LTSP/Universal_boot_floppy
11:47
<zeltron>
Sorry I must leave (it's week end and I've got to take back my children). Hope we can meet soon on the channel
11:47
boot from a floppy : it's for a room for students, not really adapted !
11:49
Must leave. Bye.

hi, my client is getting a lease but then i get tftp - pxe-t01 - file not found
15:53
<johnny>
...
15:53
more info..
15:56
<sean_>
sorry, this is my first install, the documenation seems to skip over this pivoting of control through dhcp, so I'm not sure how the client actually gets it files
15:57
<johnny>
distro
15:57
?
15:57
<sean_>
other than some magical force
15:57
ubuntu
15:57
<johnny>
version
15:57
c'mon guy.. help me help you
15:57
<sean_>
hardy heron

15:57
packages installed from repos
15:57
one nic
15:58
<johnny>
do you have /opt/ltsp/i386 ? and a reference to tftp in /etc/inetd.conf ?
15:58
assuming your thin clients are i386 ...
15:59
<sean_>
sean@irvltsp:/opt/ltsp$ ls /opt/ltsp/
15:59
amd64 images
15:59
that's a no
15:59
don't have a inetd.conf file at all
15:59
<johnny>
are your thin clients i386 ?
16:00
<sean_>
yes
16:00
<johnny>
rm -rf /opt/ltsp/amd64 and run ltsp-build-client -a i386
16:00
did you install ltsp-server-standalone ? or just ltsp-server ?
16:01
<sean_>
just ltsp-server I think
16:01
<johnny>
so you have a seperate dhcp server?
16:01
<sean_>
I'm getting a usage message on that build client command
16:01
<johnny>
if you have /etc/ltsp/ with some dhcpcd file in it. then you installed
16:02
show me
16:02
err then you installed standalone
16:02
<sean_>
sean@irvltsp:/opt/ltsp$ ltsp-build-client -a i386
16:02
/usr/sbin/ltsp-build-client: invalid option -- a
16:02
LTSP Build Client usage:
16:02
<johnny>
oh.. maybe it has to be --arch=i386
16:02
suprised it doesn't support the short option
16:02
ltsp-update-image does..
16:03
<sean_>
ok that's working
16:03
<johnny>
so, do you have a file in /etc/ltsp with dhcpcd in the name /
16:04
err dhcpd *
16:04
<sean_>
yes, I appear to have installed both
16:04
<johnny>
standalone installs server
16:04
<sean_>
ok
16:04
<johnny>
it just brings in a dhcp server and other friends
16:04
do you have another dhcp server on your network?
16:05
<sean_>
well I knew the server was working, because the client was getting a lease
16:05
on the router, it's turned off
16:05
<johnny>
here's what happens
16:05
1. network boot
16:05
2. get dhcp lease
16:05
3. download kernel and initramfs via tftp
16:06
4. boot off that kernel, load rootfs
16:06
what does the section say in /etc/ltsp/ltsp-dhcpd.conf
16:06
or whatever it's called.
16:07
should have something related to your netboot setup.. i forget which, as i don't use that dhcp server
16:07

16:08
I have edited some of that
16:08
<johnny>
see.. it's looking for i386
16:08
and you didn't have that
16:08
<sean_>
yes, I see
16:08
cool
16:08
<johnny>
are you sure you hvae no references to tftp in /etc/inetd.conf ?
16:08
could you pastebin it ?
16:08
<sean_>
could I have just changed it amd?
16:09
<johnny>
no.. your i386 clients wouldn't work
16:09
<sean_>
ok

#:BOOT: TFTP service is provided primarily for booting. Most sites

16:10
yes, it is there
16:11
build client ahs finished, do I need to restart anything
16:11
wow, it's booting
16:12
that's phenomenal
16:12
and now the login screen on the client
16:13
if I'd known it was that easy I'd have done it years ago
16:13
thank you very much johnny

<Zyna>
what do I have to do to my client station now to boot ltsp-server on my ubuntu?
16:45
<johnny>
that's too broad of a question
16:46
<Zyna>
well, as far as I understood I have to setup my grub to boot via LAN... but I'd need details on that
16:46
<johnny>
no.. you don't use grub normally
16:48
if your clients can pxe boot, then that's all you need
16:48
after installing the necessary packages

hi
16:56
I have a ubuntu LTSP server running in kvm and I am trying to network boot a real machine and also other guest machines using kvm but they all hang after getting an ip and loading the image
16:56
any ideas?
17:00
<johnny>
need more info
17:00
<bahadunn>
like what?
17:00
<johnny>
you tell me
17:00
don't know anything about kvm really
17:00
or how it might affect the network stack.. like whether you're using bridged or nat
17:01
<bahadunn>
kvm is a linux virtualization
17:01
<johnny>
i know what it is.. just not how it works
17:01
<bahadunn>
I am using bridged
17:01
actually now that you mentioned bridged I think that might be the problem
17:01
I seem to vaguely recall something about briding and certain network things not working together well
17:02
<johnny>
well i'm using bridged with virtualbox, and it works fine
17:02
with ltsp that is
17:02
but then again.. my dhcp server is external
17:02
it does get the image and boot from the virtualbox image, and vice versa on my gentoo ltsp setup
17:02
the virtualbox bridged client boots from my host ltsp server on that too
17:03
<bahadunn>
I also have a dhcp server
17:03
<johnny>
is it setup correctly?
17:03
<bahadunn>
I mean a seperate one outside of a vm
17:03
yes it is setup correctly but not for ltsp
17:03
<johnny>
does it tell where to find your image file and stuff?
17:03
<bahadunn>
I will need to configure it for that
17:03
<johnny>
modify the config to match /etc/ltsp/ltsp-dhcpd.conf
17:03
and use next-server
17:03
<bahadunn>
okay
17:03
<johnny>
to tell it to point to your vm IP
17:03
<bahadunn>
okay

hm... I managed to get into the docking station's cmos and set to boot 'LAN' however it still boots the firmware
17:20
from within the firmware I can build up a ssh connection to the host
17:26
<johnny>
firmware ?
17:26
why your docking station cmos ?
