RE: setting server rfb port to non-default - on the vncviewer
John,
vncviewer -geometry 1440x1062 -passwd z ipaddr::4918:19
/dev/null and that worked.
I think the ':19' after the port is immaterial. Try connecting to
ipaddr::4918:abcd or even ipaddr::4918abcd; it works. It makes
sense because you cannot have more than 1 display listening on a single
port (the second Xvnc will complain that it cannot bind to the given
port) unless using inetd.
-siva.

John,
No, you don't - the syntax you are specifying to your VNC Viewer
(host::port:display) is not valid. The two valid syntaxes are:
Host:port_or_display (display if 0-99, port otherwise) and
Host::port(always port)
i.e. you specify *either* a VNC display number *or* a TCP port number.
VNC display numbers 0-99 are just a short-hand for TCP port numbers
5900 to 5999.
I hate to argue with someone who has a realvnc email but my recent
experience is in direct contracdiction of what you have written:
1).I started my vncserver with options
vncserver :19 -geometry 1440x1062 -name x -rfbport 4918
(I can explain why but not relevant)
Here is the Xvnc process:
Xvnc :19 -desktop xx ... -geometry 1440x1062 ... -rfbwait 12
-rfbauth -rfbport 5919 -fp ... -rfbport 4918
NB the two -rfbport options. - the first (I assume) always
specified,
and the second from my vncserver option. And to show which one took
precedence:
here is netstat output to show which port it actually is
listening
on:
netstat -an | egrep -e 4918|5919
tcp4 0 0 *.4918 *.*
LISTEN
tcp4 0 0 ipaddr.4918 other_ipaddr.34849
ESTABLISHED
2)and now here is the command I used on my workstation to connect :
vncviewer -geometry 1440x1062 -passwd z ipaddr::4918:19 /dev/null
and that worked.
Does that convince you? If not - try it!
John

Have you tried starting the viewer with just: vncviewer -geometry 1440x1062 -passwd z ipaddr::4918 Anything beyond the port number is (presumably) ignored by the vncviewer application (whether that's by design or purely coincidental I don't know).

John, I'm afraid that you are mistaken. In the example you give, either ipaddr::4918 Or ipaddr:4918 Are valid, and will work. ipaddr::4918:19 is not a valid server specification but happens to work because of the way VNC Viewer interprets the port/display number specification.
