[ale] vnc ports?

Q53 Which TCP/IP ports does VNC use? 
A VNC server listens on two ports. The exact port numbers depend on the VNC display number, because a single machine may run multiple servers. The most important one is 59xx, where xx is the display number. The VNC protocol itself runs over this port. So for most PC servers, the port will be 5900, because they use display 0 by default.

In addition, VNC servers normally have a small and very restricted web server built in, which allows you to connect a browser to them and use the Java viewer. This runs on port 58xx. Note that this is the HTTP port used for downloading pages and applets, but once the applet is running it uses 59xx for VNC just like any other viewer. 

The servers can be changed to listen on other ports if, for any reason, these are not suitable for you. See the server's documentation for more details. Most of the viewers, if given a display number larger than 99, will interpret it as a direct port number and will not add 5900. See also the next question.

If you are running a viewer in 'listening' mode, where it accepts connections initiated by the server, it will listen for incoming VNC on port 5500

Subject: [ale] vnc ports?


well im running the vnc server, however ive got a private lan going and
our internet connection is via cable, since the ip refresh doesnt accur
much that isnt a problem yet, however, my issue is, under vnc can you set
the port it runs under? my friend and i both want to run our desktops on
vnc but currently i only know how to access one, unless we can set his
ports differently, the only way i know to access a server through a
gateway is to specify sertain port activity to go to a certain computer,
which limits it to one of us, if someone could help i would be greatly
appreciated :)
