Package: x2goclient Severity: normal 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:

""" tcp 0 0 *:31004 *:*
LISTEN 20139/x2goclient ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ tcp 0 0 *:16001 *:*

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

""" tcp 0 0 localhost:30004 *:*
LISTEN 20728/pyhoca-gui tcp 0 0 *:16001 *:*

LISTEN 6822/pulseaudio tcp6 0 0 [::]:4713 [::]:*

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