RealVNC, vnc maintainers, and whom it may concern. Recently I peeked at the iana for the official assigned port numbers. There (http://www.iana.org/assignments/port-numbers) I found that the port numbers as used in VNC are NOT registered for or assigned to vnc. However, since lower numbers are assigned, the next free (read, not assigned) are assigned for who asks for it.
I think time has come (and hopefully not gone) to register some ports for vnc usage. At least the port numbers for the rfb communication (5900 range) should be registered similar to the X11 port registrations. Hence, ask for 5900 trough 5963 (X11 uses 6000 trough 6063). Then, I don't think vnc should expect to get this entire range, a range like 5900 trough 5909 would be nice. For the 5800 range, the webserver, I see only the range 5800 trough 5812 is free. Here, I think the same range (5800 - 5809) will do. On the other hand, if the portnumbers cannot be assigned for vnc, with a little redesign of the vnc webserver, a single port (5800) can do. My idea here: Currently, the vnc-webserver uses port 5800+displaynumber to get to the display. In url, this is http://vncserver:5803/. This can also be a parameterized url: http://vncserver:5800/?display=3 or http://vncserver:5800/?rfbport=5903 . This only requires one portnumber and (for unix systems) one running vnc-webserver. I know there is a (bad documented, not configurable) portnumber in use in the 55xx range (5500, 5555?) Most of the nice numbers in this range are assigned already (without vnc in the assignment string). This port(ab)usage should be better documented and configurable. If this port is badly needed, pick a free one, ask for assignment to vnc and use that. Optionally, ask for a port number that never will be assigned to anyone and use that one if needed. Since I'm a fan of http://www.sourcecodecorner.com/articles/vnc/linux.asp, it would be nice if the portnumbers used in there stay officialy unused. I don't need them to be assigned to vnc, as long as they are not assigned to anyone else so system administrators can use them for their needs (vnc or something else) Some thoughts and ideas for discussion. Therefor I set a reply-to: header. If that does not work, please reply to the list. CBee -- C.
