Package: x2goserver Version: 4.0.1.19 Tags: patch
Hello,
I had recently had a problem with my /etc/xprofile file that prevented session startup. The details are not too important; it had to do with a difference of default shell (/bin/sh) being either /bin/dash or /bin/bash.
After enabling the 'debug' loglevel on the server, I still had no helpful output indicating what the problem might be...
I did some ferreting about and noticed that x2goruncommand was not capturing cmd output when using x2gofeature X2GO_XSESSION (/etc/x2go/Xsession). The client side invocation of x2goruncommand (via sshlib) redirects remote command output to /dev/null, so it is also not preserved when using the client's --debug option...
This small patch appends the missing output to an already existing debug file in x2goruncommand ($MESSAGE_FILE). With this in place, I was able to see the "smoking gun":
cat ~/.x2go/C-user-50-1463156913_stD.Xclients_dp24/cmdoutput
exec /root/.Xclients
Loading profile from /etc/profile
Loading profile from /root/.profile
Loading profile from /etc/xprofile
/etc/xprofile: 14: Bad substitution <-- whoop!The file is deleted (as before) if not at loglevel debug.
Thanks for your consideration.
