Dear all,
I've been using X2Go on a pair of openSUSE Tumbleweed systems. I just upgraded both and now I'm no longer able to run a remote application or desktop -- the client successfully connects to the server but then immediately disconnects. Below is output from x2goclient --debug showing me trying to launch a remote xterm. Can anyone suggest what the problem might be or how to troubleshoot further?
Regards, Tristan

Hmm, I don't see any reason in the logs you provided. Maybe try to disable printing, sound and remote dirs and retry.

Dear all,
I've been using X2Go on a pair of openSUSE Tumbleweed systems. I just upgraded both and now I'm no longer able to run a remote application or desktop -- the client successfully connects to the server but then immediately disconnects. Below is output from x2goclient --debug showing me trying to launch a remote xterm. Can anyone suggest what the problem might be or how to troubleshoot further?
Regards, Tristan

Hmm, I don't see any reason in the logs you provided. Maybe try to disable printing, sound and remote dirs and retry.

Results of some further testing:
The problem seems to happen only when connecting to the server running on openSUSE Tumbleweed. Connecting to a server running on another machine (running openSUSE Leap 15.3) still works.
The problem doesn't seem to have anything to do with the particular account I'm connecting to. I still get the automatic disconnect when logging in as a different user.

Have you tried with something else but xterm? Does xterm work when starting it via ssh -X?

Yes, I've tried launching other single applications as well (xfce4-terminal, konsole, etc.), as well as entire desktops (such as IceWM) and get the same results. Running applications remotely via ssh -X works fine.
Over the past year or so openSUSE has been gradually "hardening" their distributions (via stricter AppArmor profiles, etc.). I've had several important applications break as a result. Usually it's obvious that this hardening is the cause, and a bug report to openSUSE usually ends up with them either reversing the hardening, or else explaining why the hardening is an appropriate default and then suggesting a workaround. But in this case it's not clear to me that this hardening is the cause of the problem. My latest system update did pull in some updates to openssh but not to x2go (since I use packages I've compiled and packaged myself).
Maybe I should see if it's possible for me to roll back the openssh changes and see if that works around the problem.

What about disabling AppArmor temporarily?
From your log it seems the ssh connections are working, they are just closed preliminary. This usually happens when the last client of x2goagent/nxagent exits. Which in turn might point to something (like AppArmor/SELinux stopping xterm from running at all).

Have you tried with something else but xterm? Does xterm work when starting it via ssh -X?
Yes, I've tried launching other single applications as well (xfce4-terminal, konsole, etc.), as well as entire desktops (such as IceWM) and get the same results. Running applications remotely via ssh -X works fine.
Over the past year or so openSUSE has been gradually "hardening" their distributions (via stricter AppArmor profiles, etc.). I've had several important applications break as a result. Usually it's obvious that this hardening is the cause, and a bug report to openSUSE usually ends up with them either reversing the hardening, or else explaining why the hardening is an appropriate default and then suggesting a workaround. But in this case it's not clear to me that this hardening is the cause of the problem. My latest system update did pull in some updates to openssh but not to x2go (since I use packages I've compiled and packaged myself).
Maybe I should see if it's possible for me to roll back the openssh changes and see if that works around the problem.

I tried disabling AppArmor but that had no effect on the problem.
I also tried building nx-libs, pinentry-x2go, x2goserver, and x2goclient from the latest head commits in the Git repositories. (I'd previously been using versions from last September.) Same problem with these bleeding-edge versions. :(

Hmm, next would be you suggestions to downgrade ssh (and/or check what has changed between the old and the new version.

It seems the only change to ssh was a minor patch allowing it to read the configuration from /usr/etc/ssh/sshd_config in addition to the usual /etc/ssh/sshd_config. I reverted to the earlier build of openssh but this didn't work around the problem.
Any other ideas what might be forcing the connection closed or how I might get more information?
I did try increasing the log level of sshd but there was nothing obvious in the messages. One thing I could try is to revert my root partition to an earlier snapshot (i.e., one where X2Go works) and then try upgrading certain suspicious packages (openssh, libssh, pam, apparmor, etc.) one at a time until I find the culprit. However, that might take a lot of time.

Just to be sure: you see a successful session establishment in the sahd log?

Here's the sshd log (at the VERBOSE level) when I make an X2Go connection. Does it seem OK to you? (I'm not sure if all those starting/close session lines are normal.)

Still getting plagued by immediate disconnects, and so I did some more testing by adding "set -x" to my $HOME/.bashrc and redirecting stderr to a file. I can now see that the ssh connections seem to be fine, insofar as x2goclient is successfully connecting to the x2goserver machine, running all its shell scripts, and invoking the command to launch the remote application. It's only the remote application itself which fails to run, and only when that remote application is a graphical application. (Running headless shell scripts works fine, as long as they don't try to launch something on the X display.)
Formerly I had x2goclient set to run the command /usr/bin/xterm on the remote machine. Instead I've set it to run the remote command $HOME/bin/hello, which is the following shell script:
#!/bin/sh /usr/bin/xterm >&/tmp/xterm.errors
The contents of /tmp/xterm.errors after connecting with x2goclient are as follows:
xterm: Xt error: Can't open display: :153
So any idea what the cause might be?
Regards, Tristan
