How do I find my VNC server sessions?

From the command line on the remote machine, use the vncserver -list command to determine the display number of your VNC session. Then, run vncserver -kill to quit any sessions which need not remain open (note that you do not add 5900 in this case – use the exact display number reported).

What port does VNC use?

TCP port 5900
VNC by default uses TCP port 5900+N, where N is the display number (usually :0 for a physical display). Several implementations also start a basic HTTP server on port 5800+N to provide a VNC viewer as a Java applet, allowing easy connection through any Java-enabled web-browser.

How does Xvnc work in the NOWAIT mode?
