Not able to change VNC port in ubuntu 9.04

I am new to linux.
How do I change the listning port of the default VNC server in ubuntu 9.04(64 bit). In ubuntu 8.10 there was a tab called "Advanced" in the System-->Preferences-->Remote Desktop screen where I can specify "Use and alternative port". But this "Advanced" tab is not available in 9.04. The default port is 5900.
Can some body help me to solve this problem.

From man vncserver
vncserver is a Perl script which simplifies the process of starting an
Xvnc server. It runs Xvnc with appropriate options and starts some X
applications to be displayed in the VNC desktop.
tred@vaio:~$ which vncserver
So, open up /usr/bin/vncserver with your favourite editor and search for Port
I see this at line 127:
$vncPort = 5900 + $displayNumber;
So, I expect that if you changed the 5900 to some other number, and restarted your vncserver it would use a different range of ports.

But why do you want to do this?
If you are thinking it will be "more secure" you are mistaken.

If you want vnc to be more secure, you should tunnel it through ssh

Thanks for the reply!!

I could do this by using $gconfig-editor where I can change the port in the remote desktop option.

Thanks for the support
