Hi,

Incidentally, I discovered that sending garbage on that port make the client crash and disconnect. So you can remotely disconnect any client using x2go client. Kind of DOS isn’t it ?

I discovered it simply doing this: nmap -v -n --open -Pn -sSV --version-intensity 0 -p T:1-65535 192.168.56.0/24 crashing all x2goclients on the subnet!

Definitely, the proxy should NOT listen on INADDR_ANY but only on localhost in SshProcess::tunnelLoop.

Thanks
