Does anyone know on here if wyse r00l thin client support pxebooting?
10:56
I have looked around and cannot find any info.

<fossala>
That doesn't say but thanks.
11:37
<knipwim>
on page 23, PXE is mentioned in protocol support
11:38
<fossala>
I thought that said within the OS's
11:38
<knipwim>
yup, within xp embedded
11:38
but doesn't that mean the device supports it?
11:39
<fossala>
Yeah, I saw on a forum someone couldn't stop it pxe booting. So I guess it does support it.
11:39
<knipwim>
hehe
11:39
<fossala>
Hopefully it will work as well as my t5730.
11:40
We should make a page on the wiki of supported devices.
11:40
<knipwim>
indeed
11:40
<fossala>
Only cost 20quid so if it doesn't not a lot lost.
11:40
<knipwim>
link it to use case descriptions

Hello, can anyone help me with an error: "ndb9: unknown parition table" ?
13:16
<muppis>
Bartek, you can ignore it.
13:17
<Bartek>
What does it even mean? -.-
13:18
<muppis>
Image file does not meet all requirements of block device, but it doesn't affect to usage.

..anyone?
14:00
<fossala>
muppis said "Image file does not meet all requirements of block device, but it doesn't affect to usage."
14:00
<alkisg>
"48 persons in room" :)
14:00
<fossala>
Is that a lot?
14:01
<Bartek>
"nbd9: unknown partition table" - what does it means? ;F
14:02
<fossala>
And muppis answered it.
14:02
<Bartek>
oh
14:03
well.. I can't login on thin-client, "No response from server, restarting..."
14:04
need a solution
14:04
<alkisg>
!ltsp-update-sshkeys
14:04
<ltsp`>
alkisg: ltsp-update-sshkeys: If you changed your server IP, you need to run ltsp-update-sshkeys, and if you're using NBD (Ubuntu) you also need ltsp-update-image afterwards
14:05
<Bartek>
alskisg: tried that alredy, doesnt help
14:10
so this problem is a network-related?
14:11
<alkisg>
Bartek: ok, try to troubleshoot it. First, get a local shell on the client, by doing this:
14:11
!screen_02
14:11
<ltsp`>
alkisg: screen_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
14:11
<alkisg>
Once you do that, ping me for the next step
14:14
<markit>
hi, a dubt (not tested yet): "ltsp-build-client --arch i386 --fat-client --chroot fat-i386" produces "/opt/ltsp/images/fat-i386.img", if I then run "ltsp-update-image --arch i386", how can it know that has to create "fat-i386.img" and not simply "i386.img" file?
14:14
<Bartek>
alkisg: yeah did that, the error "unknown partition table" comes from client's /var/log/syslog
14:14
<alkisg>
Bartek: so now you have a local shell on vt2 on the client?
14:15
<Bartek>
alkisg: well i just ctrl-alt-f1 to console to check all logs
14:15
<alkisg>
Bartek: you have a root password there, and you can login?
14:16bauerski has joined IRC (bauerski!~witekb@frodo.psp.opole.pl)
14:16
<Bartek>
alkisg: console - yes, i can sudo
14:16
<alkisg>
Bartek: you're doing something wrong, there's no concept of "sudo" in thin clients
14:17
There's only 1 account, the root account, which doesn't need sudo,
14:17
and it's locked by default, so you must have unlocked it in order to login
14:18
<Bartek>
alkisg: well i tried many things along with adding one user to "sudo users".. but nevermind, shall I proceed with the instructions about shell on screen_02?
14:18
<alkisg>
Bartek: let's clear some things up first
14:18
When you try to login on the client, you use a username/password from a user that exists on the SERVER , right?
14:18
Not in the chroot....
14:19bauerski has left IRC (bauerski!~witekb@frodo.psp.opole.pl, Remote host closed the connection)
14:20
<Bartek>
alkisg: yes, exactly... but tried also with adding local-user (while chroot'ed)
14:20
<alkisg>
That would break stuff. But ok proceed with the SCREEN_02 instructions
14:20
<Bartek>
alkisg: ok
14:20
<alkisg>
From that local root shell in screen_02, try: ssh user@server
14:20
Replace "user" with an existing username on your server
14:20
Leave "server" exactly as it is, don't replace it with your server name
14:21
See if you can login, WITHOUT any warnings at all
14:21
Time to eat, bbiab
14:21
<Bartek>
alkisg: see you soon

14:27bauerski has left IRC (bauerski!~witekb@frodo.psp.opole.pl, Remote host closed the connection)
14:27
<alkisg>
Bartek: with no warnings at all? ok, now press alt+ctrl+f7 to switch to ldm and try again with the same username/password there
14:27bauerski has joined IRC (bauerski!~witekb@frodo.psp.opole.pl)
14:28
<Bartek>
alkisg: no warnings displayed in the console 02 (Welcome to Ubuntu... ), still cant login vla LDM
14:29
<alkisg>
OK bbiab :)
14:33
<Bartek>
alkisg: how about I reinstall whole server again and I wont touch anything, to save your time -.-

Bartek: sounds like a plan :)
14:36
<Bartek>
alkisg: see you tomorrow? -.-
14:38
<alkisg>
You can also just rm -rf /opt/ltsp, and run ltsp-build-client
14:39
<Bartek>
alkisg: did that like 3 minutes ago ;)
14:47bauerski has left IRC (bauerski!~witekb@frodo.psp.opole.pl, Quit: Leaving.)

alkisg: just an info: rebuilding the client didnt help
14:52* markit was going to ask a question to alkisg about --mount-package-cache but just found, googling, in a chat log that has been answered in feb 2011 by... alkisg :)

<knipwim>
any LTSP Ubuntu people around?
16:41
how is the initramfs made?
16:42
more specifically, where? in the ltsp-build-client process? or somewhere else?
16:49
<alkisg>
knipwim: when a new kernel is installed, update-kernels is ran, and that runs some hooks, and one of the hooks installs ltsp

17:07xsl has left IRC (xsl!~silence@static-b4-252-232.telepac.pt, Ping timeout: 248 seconds)
17:12
<knipwim>
thx, i see, ltsp-update-image is the key
17:23
<alkisg>
knipwim: no, the initramfs is generated with NFS too, it's not a requirement to use NBD
17:23
(ltsp-update-image is for NBD)
17:24
$ ls /opt/ltsp/i386/usr/share/initramfs-tools/scripts/
17:24
functions init-premount local local-top nfs nfs-top
17:24
init-bottom init-top local-premount ltsp_nbd nfs-bottom panic
17:24
E.g. ltsp_nbd is one of our scripts, nfs-bottom/ltsp is another...
17:25
And that folder, /opt/ltsp/i386/usr/share/initramfs-tools, is transferred to the initramfs when the initramfs is generated
17:25
And the initramfs is generated when a new kernel is installed, either with ltsp-build-client, or from a kernel update
17:39
<knipwim>
and together with the scripts in initramfs-scripts.d the whole client is basically prepared for the user session

<Yoe>
alkisg: your patch is in the latest nbd package
20:42
unfortunately it doesn't build on sparc and s390x for some reason, but that's a different matter
20:42
<alkisg>
Cool!! Thank you Yoe, I'll try to make LTSP switch to using your script in a later version. Happy new year btw.
20:43
<Yoe>
same to you :-)
20:44
alkisg: it had been in for a few days already, it's just that you weren't on IRC when I tried to tell you :-)
20:44
<alkisg>
Haha... is it unstable?
20:44
*in
20:44
<Yoe>
alkisg: no, the test suite produces a bus error
20:45
ah, yes, it's in unstable :-)
20:45
<alkisg>
Sweet
20:50
Hmm if it goes into testing by Jan 12th, it'll be in Ubuntu Precise too
20:51
https://wiki.ubuntu.com/PrecisePangolin/ReleaseSchedule => LTS DebianImportFreeze
20:51
<Yoe>
alkisg: I'll try to make that happen, but I can't promise right now
20:51
I don't even know (in detail, at least) why the bus error happens yet at this point
20:51
<alkisg>
If needed I think it can also be pulled manually
20:52
<Yoe>
yeah, I was about to suggest that too :-)
20:52
<alkisg>
But I don't think LTSP will use it for 12.04, probably in the next version, so no hurries... /me would use it in his own installations though
