Hi Mihai,

Interesting. Thank you for pointing that out. I would like to correct this to 
run with a supported stack then.

Apologies if I'm missing something obvious, but is there documentation that 
shows how to install from your repositories on RHEL 7?



I installed x2goserver following the instructions from the 
wiki<https://wiki.x2go.org/doku.php/doc:installation:x2goserver>:



RHEL 7

Add the EPEL repository:

EPEL Installation 
Intructions<https://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F>

Check that you have activated the "optional" channel:

sudo subscription-manager repos --list

If the optional channel for your base channel is not active, activate it.

sudo subscription-manager repos --enable=rhel-7-server-optional-rpms

Or use the RHNS web interface to activate the channel "RHEL Server Optional"

Then

sudo yum install x2goserver x2goserver-xsession



Looking through my yum history confirms what you said about the software coming 
from EPEL:

That's the old, more or less unsupported version and additionally provided by
EPEL, not by our repositories.

I'm afraid I can't offer a lot of help here.

You could look into ~/.x2go/C-/session.log to see what the
server-side process logged out.

At some point it must have failed to run correctly, otherwise the client-side
nxproxy would have been able to connect successfully.

Debugging such issues is always difficult.

One new update on this issue:

Updated x2gosever on one of the servers that was showing the issue to 
x2goserver-4.0.1.22-2.el7.x86_64. After the update, access through that server 
started working again.

Any guidance to understand the root cause would still be greatly appreciated.

One additional detail that we discovered after further troubleshooting:

We have multiple backend servers running X2go. All servers have identical

stuck in this state where applications won't launch while a third identical 
sever is not showing issues.

[X2Go-User] X2Go Client suddenly failing to connect

2018-03-26 Thread Ivan Gomez

Dear all,

I have been using X2Go client in the current environment for quite a while now 
without issues. Seemingly all of sudden today an outage happened where X2Go 
will no longer launch any applications.

The connection seems to succeed in the backend:
[cid:image001.png@01D3C558.EB0F51C0]

However, the client closes the connection before anything happens. Running the 
client with the debug terminal shows these messages:
[cid:image002.png@01D3C559.58693F10]

I've validated that I can SSH to the server using other tools and start the X11 
applications from command line directly.

Any guidance or pointers to figure out why X2Go stopped working would be 
greatly appreciated.

Thank you,
Ivan G.
