I am having trouble connecting remotely to my Linux desktop (Centos 6.3, GNOME 2.28.2) from my Windows 7 laptop. I have the same (latest) version of NoMachine installed on both v 4.0.366.
The error I get when attempting to connect is
“Could not connect to the server. Error is 138: Connection timed out”
I have tried googling this problem and looking at the forums here, neither of which has helped me solve the problem thus far. One additional note, when I looked at my server settings on the Linux machine it was unable to find my gateway ip address or a port to forward to the gateway.
I have attached the session log for my most recent attempt in case it is useful. I would love to have this problem solved today, as I am about to leave town and *need* to have remote work capability on my linux machine. I can always ssh to it but my connection tends to time out and it is very slow to work with GUIs in this fashion. Thank you all for your help!
