some simple questions on VNC



  nothing serious, just some grotty details to clear up.

1) on the server side, is the equivalence between the listening TCP
port and the display number a 1:1 mapping?  that is, does port 5901
always represent display number :1, port 5902 display number :2 and so
on?  it certainly *seems* that way, i just want to make sure.

2) apparently, although the man page for "vncviewer" doesn't mention
it, you can view to a given port number rather than a display number.
so either of the following would work equally well:

  $ vncviewer 192.168.1.100:5
  $ vncviewer 192.168.1.100:5905

although as long as there is that 1:1 mapping, there would seem to be
little point using the port number since the display number would work
just as well and is clearly shorter.

3) on the server side, what is the purpose of the *other* ports
associated with each listening port?  that is, after i start vncserver
listening on port, say, 5917, i can see listening ports 5817 and 6017
suddenly active as well.  what are they for?
