I have followed this thread but I remain unable to connect either locally or remotely when using xinetd.  Otherwise, launching Xvnc directly on the command line allows me to connect without any problem.

I'm testing using Feisty as both client and server.  The server shows these errors when I attempt 'vncviewer <IP>:1':


Jul  5 05:58:28 feisty-D86-2 xinetd[29601]: warning: can't get client address: Transport endpoint is not connected
Jul  5 05:58:28 feisty-D86-2 xinetd[29602]: warning: can't get client address: Transport endpoint is not connected
Jul  5 05:58:28 feisty-D86-2 xinetd[29603]: warning: can't get client address: Transport endpoint is not connected
Jul  5 05:58:28 feisty-D86-2 xinetd[4792]: Deactivating service Xvnc due to excessive incoming connections.  Restarting in 10 seconds.
Jul  5 05:58:38 feisty-D86-2 xinetd[4792]: Activating service Xvnc


The server is running:

vnc-common 3.3.7-13ubuntu2                        
vnc4server 4.1.1+xorg1.0.2-0ubuntu4              
xvnc4viewer 4.1.1+xorg1.0.2-0ubuntu4

The client is running:

xvnc4viewer 4.1.1+xorg1.0.2-0ubuntu4

When Xvnc is run manually I can connect both locally and remotely when using 'vncviewer <IP>:2'.  Here is what is run:

$ ps ax | grep Xvnc
29206 pts/0    S      0:00 /usr/bin/Xvnc :2 -query localhost -geometry 800x640 -depth 16 -fp /usr/share/fonts/X11/misc -DisconnectClients=0 -NeverShared passwordFile=/root/.vnc/passwd -extension XFIXES
