[X2Go-Dev] X2Go Server + NXLibs

[Bogdan-Andrei Taru]

Hi,

I'm trying to connect to a self-compilted and rpm-packaged X2GO Server (the self-compiled/packaged NX LIbs are installed). I also liked x2goagent to nxagent:

[root at rhel6-64 x86_64]# ls -al /usr/lib/x2go/x2goagent 
lrwxrwxrwx. 1 root root 16 Feb  4 04:01 /usr/lib/x2go/x2goagent -> /usr/bin/nxagent

But the connection still doesn't work. This is what the X2Go Server logs (debug mode):

This is what the client logs on the console:

Any ideas?
