| 09:41 | <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
| |
| 09:52 | gvy 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
| |

| 11:51 | <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

| |
| 12:17 | dadada is now known as Guest27567 | |
| 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)

| 14:24 | ben_roose has joined IRC (ben_roose!~roose@roose.cs.wichita.edu) | |
| 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
| |
| 14:48 | mikkel has left IRC (mikkel!~mikkel@mail.dlvs.dk, Quit: Leaving) | |
| 14:51 | <alkisg> 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

| 19:01 | <sebd> We have been using PRINTER_0_DEVICE=/dev/usb/lp0
| |
| 19:02 | seems enough
| |

| |
| 19:03 | The sysvinit script is fine
