<Statler>
I have some trouble with the nbd-client 3.14 on a nbd-server 3.8
10:26
the host.allow-issue I have read
10:56
<alkisg>
Statler: what issue? isn't that just a warning?
11:15
<Statler>

11:15
upps
11:15
nbd_server[21813]: Negotiation failed/8a: Requested export not found
11:15
but this seems to be in issue from the 4.8 kernel
11:21
<alkisg>
Statler: which distro/version are you using?
11:21
<Statler>
stretch :(
11:21
<alkisg>
I haven't heard of any such issues, it sounds like a misconfiguration in your nbd server
11:22
<Statler>
the nbd-server is running on jessie
11:22
<alkisg>
!nbd-client
11:22
<ltsp>
nbd-client: To try mounting the NBD image from the client initramfs: nbd-client 192.168.67.1 -N /opt/ltsp/i386 /dev/nbd0
11:22
<alkisg>
Wake up bot and reply... :)
11:22
<Statler>
i have comment out the host-allow
11:22
<alkisg>
Statler: try that ^ command from the client
11:23
Also, what's the output of this command on the server? grep -r . /etc/nbd-server | nc termbin.com 9999
11:23
<Statler>
I have tried it with my station (not diskless) and found the new nbdtab
11:24
after configuring the nbdtab it works on my station
11:24
<alkisg>
What is the nbdtab?
11:24
<Statler>
but, the diskless stations boot over pxe
11:24
<alkisg>
There's no such thing here in my stretch box
11:24
<Statler>
/etc/nbdtab
11:25
you runned the upgrade on weekend?
11:26
<alkisg>
No
11:26
What's the output of this? dpkg -S /etc/nbdtab
11:26
<Statler>
nbd-client: /etc/nbdtab :)
11:27
<alkisg>
Wow, changes! :)
11:27
<Statler>
Paket: nbd-client
11:27
Version: 1:3.14-4
11:27
yes :(
11:27
<alkisg>
Let me read the changelog...
11:27
Btw, does that command that I said, work?
11:28
!nbd-client
11:28
<ltsp>
nbd-client: To try mounting the NBD image from the client initramfs: nbd-client 192.168.67.1 -N /opt/ltsp/i386 /dev/nbd0
11:31
<Statler>
works
11:31
very strange
11:32
<alkisg>
So, /etc/nbd-client was converted to /etc/nbdtab. LTSP uses neither of those, it mounts nbd from the initramfs.
11:33
So nbdtab shouldn't cause any issues at all
11:33
<Statler>
I have made a nbdtab that works on my station
11:34
<alkisg>
It's not related to ltsp at all though
11:34
LTSP neither creates nor uses nbdtab
11:36
<Statler>
much more a problem from pxe-boot im afraid
11:36
<alkisg>
Can you upload a screenshot of your client boot messages, exactly when it fails to boot?
11:36
<Statler>
manual from initramfs
11:36
<alkisg>
E.g. from a mobile phone...

11:37
<alkisg>
Those messages are completely normal
11:39
<Statler>
but the station doesnt boot ;)
11:39
i have switched to NFS for now
11:39
<alkisg>
But it does show messages why it doesn't boot, right?
11:39
Like, nbd failure etc
11:39
So that we see at what exact point the problem happens
11:40
<Statler>
the initramfs was booted
11:40
i have added explicit now the nbd module to initramfs
11:40
with no effect
11:41
<alkisg>
That doesn't help either :)
11:41
<Statler>
the initramfs comes over aftp
11:42
than the kernel try to establish the root via nbd
11:42
right?
11:42
<alkisg>
tftp, not aftp
11:42
Right
11:42
<Statler>
yes tftp
11:42
confusing with the server-process-name ;)
11:44
<alkisg>
You can also take a picture of the client messages with a virtualbox client
11:45
<Statler>
"Negotiation: ..Error: Read failed. End of file
11:45
"Exiting
11:46
<alkisg>
And the lines above that?
11:46
<Statler>
"Gave up waiting for root device. ...
11:46
<alkisg>
And above?
11:46
<Statler>
Noting above that
11:46
<alkisg>
And above?
11:46
At what point did it take an ip?
11:46
Before of after the nbd-client initscript?
11:46
<Statler>
before
11:46
<alkisg>
So there is something above :)
11:47
<Statler>
the screen was cleared before :(
11:47
perhaps console-setup or something like that :(
11:47
<alkisg>
What's the output of this command on the client initramfs?
11:47
cat /proc/cmdline

Hi
17:01
I have a problem with LTSP. Anybody that can share some knowledge?
17:02
Currently running LTSP with linux mint image. We have multiple sites and want to show a whiptail menu to rdesktop or localboot etc..
17:02
on our Dell optiplex thin clients.. its works perfectly. On our HP T610 we keep hitting a black screen.
17:03
Both are in PXE boot, both on the same site. (testing it in local lan)
17:05
in the LTS.conf we push the sisimedia driver to the Dell Optiplex.
17:07
Is it also necessary to define the graphic driver for the hp? There is a Radeon 6300 in there.
