It depends on the OS but the basic idea is to overflow the number so it will wrap around and start back at zero. On my machine, setting the port to 65616 will let vnc listen on port 80. 65557 will get you at port 21. The max value of a word wich is four bytes is FFFF or 65535.

I'll explain my situation to begin: I am running a VNC server at home off a cable modem. I want to be able to access this server from work. The problem occurs because my work has a firewall that blocks all outgoing ports except for standard service ones. I can FTP out using port 21 and I'm sure port 80 is available because I can access websites. Port 5190 is also open as I have connected to it. Now, I want to be able to run the VNC Server on port 21, so that I can access it from work - thinking it will bypass the firewall's protection of non-standard ports. The VNC FAQ says you CAN do this - but doesn't explain HOW to do this. I know you can run VNC Server on anything 5900+ by changing the display number from 0-99. Anything above 99 will change the VNC server to run on the actual port. Now to run the server on ports BELOW 99 is what I want to do. VNC FAQ explains how to CONNECT to these servers, but not how to set the server up like that. I put 21 in the Display Number and the server runs on port 5921. I cannot put a negative number in the box (won't let me) like the FAQ suggests you do with the viewer to connect. So... what are the suggestions for getting around my firewall? Will using ports 21, 23, 80 work? How do I set VNC SERVER to run on these ports? I dont want to have to use Remote Admin or PC Anywhere :/ Thanks! _________________________________________________________________ Join the worlds largest e-mail service with MSN Hotmail. http://www.hotmail.com _______________________________________________ VNC-List mailing list [EMAIL PROTECTED] http://www.realvnc.com/mailman/listinfo/vnc-list _______________________________________________ VNC-List mailing list [EMAIL PROTECTED] http://www.realvnc.com/mailman/listinfo/vnc-list
