Hi guys, Do I miss the joke in the below commit??? (see below!) And: the video is not viewable inside Germany. And: luckily Mihai reverted this commit...

What really happened here is that something triggered an update of your out-of-date packages lists. (That is, that stuff that happens when one runs (sudo) apt-get update or (sudo) aptitude update.) They likely weren't just out-of-date, but plainly not existent, explaining the uninstallable packages. > Resolution: > I added the missing repositories contrib and non-free and the > installation was possible without errors. I guess running sudo apt-get update or sudo aptitude update or letting synaptics update the package lists (no idea how to do this with synaptics, sorry) would have been enough. You should be able to remove contrib and non-free, then update the package lists by some mentioned means. After that, installing x2goserver and other components should still be possible (but any tests at this point are moot, because the x2goserver package is already installed on that machine.) > The report can be closed. Done! Thank you. Mihai

Bug#835: x2gobroker-ssh: cannot execute x2gobroker-agent if agent-query-mode is set to LOCAL
by Mike Gabriel 02 Apr '15

02 Apr '15

Package: x2gobroker-ssh Severity: important Version: 0.0.3.0-preview x2gobroker-ssh cannot execute x2gobroker-agent if agent-query-mode is set to LOCAL. Reason: /usr/bin/x2gobroker-ssh is installed with these permissions: -r-sr-x--- 1 x2gobroker <x2gobroker-users> 6168 Apr 1 06:24 /usr/bin/x2gobroker-ssh That means: only users that are members of the POSIX group <x2gobroker-users> (in Debian/Ubuntu, this is configurable via DebConf) can launch a fully featured X2Go Session Broker instance via SSH brokerage. A user that is member of group <x2gobroker-users> launches x2gobroker-ssh and the process permissions are these: real uid: <uidNumber-of-the-user> real gid: <gidNumber-if-the-user> effective uid: x2gobroker effective gid: <gidNumber-if-the-user> So, the setuid flag on /usr/bin/x2gobroker-ssh changes the effective user ID, but not the effective group ID. If agent-query-mode is set to LOCAL, x2gobroker-ssh directly calls /usr/lib/x2go/x2gobroker-agent (via subprocess.Popen) and fails, because of insufficient priveleges: -rwsr-x--- 1 root x2gobroker 6168 Apr 2 06:39 /usr/lib/x2go/x2gobroker-agent Only users that are members of POSIX group "x2gobroker" can launch the x2gobroker-agent script (and gain root priveleges). In a sane environment, no user is member of this group (except the user "x2gobroker"). Solution: --------- (root@medoc) {~} # cat /etc/sudoers.d/x2gobroker-ssh # Allow members of group x2gobroker-users to execute any /usr/lib/x2go/x2gobroker-agent %x2gobroker-users ALL=(:x2gobroker) /usr/lib/x2go/x2gobroker-agent If the user launching x2gobroker-ssh is member of the group <x2gobroker-users>, then the LOCAL query to the x2gobroker-agent is run via sudo. If the evoking user is not a member of the <x2gobroker-users> group, then no sudo gets used (e.g. for executing the x2gobroker-agent via agent-query-mode SSH or via agent-query-mode through the http broker implementation. A patch is in prep and should be committed soon.

Bug#834: defaults.py X2GOBROKER_SESSIONPROFILE_DEFAULTS dpi prevents client from using autodetected dpi
by Jason Alavaliant 01 Apr '15

01 Apr '15

Package: python-x2gobroker Version: 0.0.2.3 Tags: patch It was noted by my users that their x2go sessions started via the broker always got the default dpi setting of 96 instead of the dpi value native to their machine. Tracing through the code as far as I can see the problem is that if the /etc/x2go/broker/x2gobroker-sessionprofiles.conf file doesn't have a dpi= setting defined in it the default one is provided by the value in the /usr/lib/python2.7/dist-packages/x2gobroker/defaults.py file under X2GOBROKER_SESSIONPROFILE_DEFAULTS that's not ideal since it stops the client from supplying it's autodetected one which matches the actual dpi on the user's machine. I'd suggest updating the /usr/lib/python2.7/dist-packages/x2gobroker/defaults.py file to remove the line "u'dpi': 96," from the X2GOBROKER_SESSIONPROFILE_DEFAULTS section (as per the attached patch). In my testing with that default value gone (assuming that setdpi=1 is set); * If a dpi=num value is set in x2gobroker-sessionprofiles.conf (which is the default provided in the sample config file), then that sessionprofile set dpi value is used by the session. * If there is no dpi=num value set in x2gobroker-sessionprofiles.conf then that the x2goclient provides it's own value which is either the autodetected value matching the dpi of the machine that is being connected from or the client falls back to it's default value which is also 96 So as far is I can see in default cases having that default value removed shouldn't change behavior and it would allow people optionally configure their sessionprofiles to have no dpi value set so broker sessions would be free to use the native dpi value provided by the client (which doesn't seem to be possible currently due to the default overriding the client providing it's own value). Thanks Jason
