|
|   $ 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?

The 58xx ports fire up a java version of the VNC viewer so you can use
VNC inside a web browser.
