VNC and X have opposite ideas of which ends are the "client" and the
"server", so a proxy between them acts as "server" on both sides.
So xvnc listens on *two* ports -- one as a VNC server, and one as an X
server; and I gather that they're numbered 5900+x and 6000+x. Note that 6000
is the default X server using the local keyboard and screen (often VT7);
picking numbers bigger than 99 are not likely to work as you'd expect.
If it seems like one listener appears but the other does not, check netstat.
If netstat says there are two listeners, check your firewall rules. If
netstat says there is only one listener, then check your VNC config.
