How to make tightvnc listen for incoming connections on port 5900?

Question

I'm running tightvnc on a raspberry pi and looking at the log

/root/.vnc/hostname:5900.log

I see this line:

30/04/14 09:23:18 Listening for VNC connections on TCP port 11800

How can I change this so it listens on port 5900?

Solution

Tehehe, you got the schema behind the command line wrong. The argument you give to tightvnc is the display number, not port number. Display numbers correspond to port numbers in the way that

port = display + 5900

So display 0 would result in port 5900, display 5900 in port 11800. Took me a while, too. ;)
