Yea, anything that tries to do ioctl or change permissions on stdio
seems to fail as well, a simple, "mesg n" causes it to blow up and unfortunately that is standard in /etc/profile of most modern distributions.

Subject: Re: [X2Go-User] Compatibility between x2go deb packaged versions



Hi All !

Just for common knowledge, I solved an issue that some of
you can encounter some days.

Actually, during connexion, it looks like
the x2go client parse some text returned by the ssh connexion. I did not
browse the code to know more but I am pretty sure of that.

If you
modify the /etc/profile file of the x2go server, for any reason (custom
script, ...) and that it output some text, you may experience connexion
problems. I shutted down the output of my scripts with a > /dev/null
redirection and everything worked fine.

If someone can explain a bit
more I would appreciate.

Cheers :)

Hi to all !

I've got a x2go
server 4.0.1.20 running on debian 8, and I am surprised that my
x2goagent 4.1.0.0 running on debian 9 fails to connect to the server...


The error message is : "Unable to create SSH tunnel : Connexion
error on localhost:1000"

Is there a way to maintain compatibility
between versions ? What are the recommendations ?

Thanks !
