I’m trying to set up a shared VNC server configuration where the session is kept alive even if the VNC client closes the connection. I had this running on a 10.2 box, but fail to get it going on 11. Here’s the section from /etc/xinetd.d/vnc (based on some instructions I found elsewhere).
service vnc2
{
type = UNLISTED
disable = no
socket_type = stream
protocol = tcp
wait = yes
user = root
server = /usr/bin/Xvnc
server_args = -inetd -query localhost -geometry 1220x960 -depth 16 -once -DisconnectClients=0 -NeverShared passwordFile=/root/.vncpasswd
port = 5902
}
Client-Connection fails and /var/log/messages says
Aug 8 13:14:52 gandalf xinetd[3780]: warning: can't get client address: Transport endpoint is not connected
a couple of times and then
Aug 8 13:14:52 gandalf xinetd[3585]: Deactivating service vnc2 due to excessive incoming connections. Restarting in 10 seconds.
Having pretty much the same issue on 10.3 since updating to the latest version yesterday. Not much else in the logs to tell me what’s wrong either.
in xinetd wait = no fixes the problem ,but then the session is ended whenever you disconnect.
Running Xvnc standalone on the command line works fine too.
I’d consider creating a service and running it without xinetd, but don’t have the time to figure out how to write my own service scripts
Well, I really need this, so here’s my flavor of an xvnc start script. Copy into /etc/init.d, adjust the params in line 119, run insserv, deactivate xvnc in xineted and activate the new script in the run level editor. Works fine for me on OpenSuse 11.
(I’ve cut some comments from the original sekelton so that it fits into the post limits here)

Thanx for the script HG, but after creating the script file, when i use the command activate xxxxx (filename), an error message displays stating: “not a block device”.
What can be the cause of that?
