Hi Alex, hi Heinz,

i have a problem that occured when coding Python X2go...

I have two servers. None of them has any X2go users connect to them.

When I connect to server 1 it offers SSH display tunnel NX-Proxy port 30001.

When I connect to server 2 it also offers SSH display tunnel NX-Proxy port 30001.

However, I cannot start two nxproxy instances listening on the same SSH tunnel port.

Is there a communication protocol in X2go that gives the server feedback if an offered port is already in use locally on the client? It actually is not only a graphics/nxproxy issue, it will also occur when tunneling sound or sshfs (only that I do not get that far without a tunnel for nx traffic).

Any help is appreciated...

Greets, Mike

Hello Mike,

You can try to connect with specified port, just before you opening a tunnel or starting the service that should listen to that port. If the connection failed, port is unused and you can use it.
