Package: nxagent Version: 3.5.0.27 Severity: important 17:02 < bigfoot-> hmmm. x2goagent is started with -extension XFIXES -nolisten tcp -nolisten tcp -dpi 96 -D -auth /fs/staff/hsc/.Xauthority -geometry 800x600 -name X2GO-hsc-51-1412262126_stDmyxfce_dp24 :51 17:02 < bigfoot-> :50 is the already running (first) session 17:03 < bigfoot-> and x2goagent dies with https://pbot.rmdir.de/tt64QL-NNXqZomZoahDhJg [...] 17:08 < bigfoot-> woglinde: I had to remove remaining /tmp/.X*-lock and /tmp/.X11-unix/X* that were owned by other users. Works like a charm again now. 17:09 < bigfoot-> iow, a reboot would've helped, too (if it cleans up /tmp, that is). but that's a non-option on this machine. [...] 17:23 <@sunweaver> please report it as a bug!!!! 17:24 < bigfoot-> I'm still investigating; seeing this issue again now. The process is as follows: 17:25 < bigfoot-> - some user logs in, gets :50 17:25 < bigfoot-> - some user logs in, gets :50 17:25 < bigfoot-> - /tmp/.X50-lock and /tmp/.X11-unix/X50 are owned by him now 17:25 < bigfoot-> - user logs out, which doesn't succeed completely (due to some yet unknown reason; he's got a default xfce setup in his home) 17:26 < bigfoot-> - user logs in via ssh and kills all his processes via killall -u username 17:26 < bigfoot-> afterwards, x2go seems to assume :50 is free, but the two aforementioned files still exist 17:26 < bigfoot-> the next user gets assigned :50, but this fails as the user doesn't have the permissions to access these files 17:27 < bigfoot-> So, who (or, which part of x2go) is responsible for removing these files? When does/should this happen? 17:51 < bigfoot-> sunweaver: this change seemingly only changes the output, does this have an effect on the cleanup stuff? 17:51 <@sunweaver> no 17:51 <@sunweaver> the fix is four smoothing out mkigration from 4.0.1.15 to higher... 17:52 <@sunweaver> though there could be unexpected side effects... 17:52 <@sunweaver> there also is a patch in NX I introduced lately... 17:53 < bigfoot-> ok, but how should the new x2golistsessions and x2golistsessions_root affect my issue with cleanup? 17:55 <@sunweaver> http://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=debian/patches/027_nxcomp_abstract-X11-socket.full%2Blite.patch;h=4f614338cd51e19e05de87d097d623065d826d56;hb=bddc7e0ba4cef393ce56f75d1eb03255fe5ac6e1 -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby fon: +49 (1520) 1976148 GnuPG Key ID 0x25771B13 mail: mike.gabriel@das-netzwerkteam.de, http://das-netzwerkteam.de
