If Xvnc uses one port for RFB then with the current implemenation it wont be possible to open two display from Xvnc.

We already have that. A typical Xvnc listens for X apps on :1 and also listens for VNC clients on :1, where :1 and :1 are two completely different things. :-/ It's even possible, though rare, to have Xvnc use completely different display numbers for X and RFB, which could be incredibly confusing to someone who doesn't understand the difference between :1 and :1. And the system breaks down completely if you have 100+ displays. It would be a lot less confusing if all VNC implementations used a single port for RFB. Xvnc would still have an X display number, but anyone using X can be expected to figure that out. The current system only makes good sense on one platform, and it doesn't scale. > I agree it doesn't make much sense in the Windows-only world; however, > when connecting to *nix systems (from any system) it does make sense, > and (in my opinion) should not be removed. In a VNC implementation with a single port serving multiple displays, each display would still need some kind of identifier, and it would make sense for Xvnc to continue to use the X display number for that purpose. It would even work with display numbers > 99, which would be refreshing. > Perhaps what we need is a way to explicitly specify the VNC port (the > 580x/590x) on both the client and server.

It would be nice if other implementations had that feature as well. -- Mike Ossmann, Tarantella/UNIX Engineer/Instructor Alternative Technology, Inc. http://www.alttech.com/ --------------------------------------------------------------------- To unsubscribe, mail [EMAIL PROTECTED] with the line: 'unsubscribe vnc-list' in the message BODY See also: http://www.uk.research.att.com/vnc/intouch.html --------------------------------------------------------------------- --------------------------------------------------------------------- To unsubscribe, mail [EMAIL PROTECTED] with the line: 'unsubscribe vnc-list' in the message BODY See also: http://www.uk.research.att.com/vnc/intouch.html ---------------------------------------------------------------------
