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 *:* LISTEN 6822/pulseaudio tcp 0 0 *:4713 *:* LISTEN 6822/pulseaudio tcp 0 0 localhost:44610 localhost:ssh VERBUNDEN 20139/x2goclient tcp 0 0 localhost:44609 localhost:ssh VERBUNDEN 20139/x2goclient tcp 0 0 localhost:45257 localhost:31004 VERBUNDEN 20161/nxproxy tcp 0 0 localhost:31004 localhost:45257 VERBUNDEN 20139/x2goclient tcp 0 0 localhost:31004 localhost:45257 VERBUNDEN 20139/x2goclient tcp6 0 0 [::]:16001 [::]:* LISTEN 6822/pulseaudio tcp6 0 0 [::]:4713 [::]:* LISTEN 6822/pulseaudio """ 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 tcp 0 0 *:4713 *:* LISTEN 6822/pulseaudio tcp 0 0 localhost:30004 localhost:52107 VERBUNDEN 20728/pyhoca-gui ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ tcp 0 0 m-110.informatik.:41910 fylgja.das-netzwe:32032 VERBUNDEN 20728/pyhoca-gui tcp 0 0 localhost:52107 localhost:30004 VERBUNDEN 20773/nxproxy tcp6 0 0 [::]:16001 [::]:* LISTEN 6822/pulseaudio tcp6 0 0 [::]:4713 [::]:* LISTEN 6822/pulseaudio """ Output with lsof -i is even more weird, as lsof -i shows that nxproxy is listening on all TCP/IP addresses, not X2Go Client.
