<sebd>
Hello, "su[14720]: pam_systemd(su:session): Cannot create session: Already running in a session" happens when login out then login again (thin clients)
09:50
one has to kill -9 -1 its own processes via ssh so to be able to open one's session
09:50
systemd --user is the culprit : it does not stop at the end of the XFCE4 session
09:52gvy has joined IRC (gvy!~mike@altlinux/developer/mike)
10:05
<sebd>
found a fix : "KillUserProcesses=yes" in /etc/systemd/logind.conf
10:34
nbd-client gets blocked on ltsp client machines (blocked for more than 120 seconds)
10:36
maybe we should get back to NFS here

11:21
<alkisg>
sebd: nfs doesn't work well with overlayfs in recent kernels. Read as "it's so broken it doesn't even boot"
11:22
The blocked nbd issue though, I've only seen it in clients with bad network cables
11:29kjackal_ has joined IRC (kjackal_!~quassel@2a02:587:3116:4c00:dcd4:a678:8b43:dbf7)
11:51
<sebd>
ok, we have nbd0 on /rofs, nbd1 as swap, but we also have kernel error message about nbd9 connexion timing out, as soon as the ltsp boots or later on
11:51
what is nbd9 for ?
11:52
<alkisg>
Testing if there's a newer image available, in order to reboot the clients
11:52
It also connects to ltsp_i386.img
11:52
<sebd>
ok
11:54
is "ltsp_i386.img" hardcoded somewhere ?
11:54
(we only have amd64 images)
11:54
<alkisg>
dnsmasq, nbd...
12:12
<sebd>
I cannot find it in the whole ltsp client image
12:13
<alkisg>
It's on the server
12:13
Why?
12:14
<sebd>
I want to understand what script tries to mount nbd9 (because that's the one creating problems I think)
12:16
<alkisg>
grep nbd9 /usr/share/ltsp
12:16
grep -r nbd9 /usr/share/ltsp

none

12:17
<alkisg>
grep -r nbd9 /usr/share/ldm
12:18
<sebd>
no such folder (on the server)
12:18
found it in the client chroot (where ldm is installed; of course)

14:40
<alkisg>
INIT_COMMAND_STOP_NBD9="rm -f /usr/share/ldm/rc.d/I01-nbd-checkupdate"
14:41
sebd: you can test with this ^ in lts.conf
14:42
<sebd>
alkisg: we found inserting "return" at top of I01-nbd-checkupdate does fix our issue, so yes, we want to rm it at boot if possible
14:44
<alkisg>
sebd: I just saw a client using debian having the same issue
14:44
So it's possible that it's a kernel regression
14:44
I saw something similar in recent Ubuntu, but it only caused errors in dmesg, with no visible issues
14:47
<sebd>
root@ehlg:/home/ldd# vim /srv/tftp/boot/lts.conf
14:48
sorry

No worries, as long as it's not your bank password we're not interested
15:06
!printer
15:06
<ltsp>
printer: Quick how-to: RCFILE_01="/usr/sbin/jetpipe /dev/usb/lp0 9100 &" in lts.conf, reboot client, then go to server's add printer dialog, and specify network printer → jetdirect → ltsp123.local

We have been using PRINTER_0_DEVICE=/dev/usb/lp0
19:02
seems enough
19:02
(on Debian 8 at least)

Yes it's only Ubuntu's upstart job that has the bug
19:03
The sysvinit script is fine
