Version: 3.99.3.0-prerelease

Hi all,

I just stumbled over an issue that we maybe have to address. Probably  
in X2Go Client, I guess.

X2Go Client launches nxproxy and netstat -ap delivers this output:

PyHoca-GUI with Python X2Go in its back, however, deliveres this  
output with netstat -p:

Output with lsof -i is even more weird, as lsof -i shows that nxproxy  
is listening on all
TCP/IP addresses, not X2Go Client.
