vncserver won't start from rc.local

GD_19 · 01-15-2004, 01:53 PM

Hi! I have created the following /etc/rc.local file in order to set up vnc at boot time:

touch /var/lock/subsys/local
/sbin/route add -net 140.143.0.0/16 gw 10.143.7.1
/etc/init.d/vncserver start
/usr/bin/vncserver :1 -geometry 1280x1024
/usr/bin/vncserver :2 -geometry 800x600

however either the vncserver service does not start, or no X11 sessions are started from the /usr/bin/vncserver script.

The problem is that should I enter these same commands at the command line or execute the rc.local file after the system has booted, everything works fine!

Moreover running an nmap after starting vnc also starts a service named vnc-http-1 at port 5801. I can only connect to port 5901 which the vnc-1 service listens to. What is the use of the vnc-http-1 service?

Thanks!
GD

The http port is used to load the java viewer via a web browser.

Try creating a logfile for those commands to see if it gives you more information - change the commands to:
/etc/init.d/vncserver start 2>&1 > /tmp.vncserver1.log
/usr/bin/vncserver :1 -geometry 1280x1024 2>&1 > /tmp.vncserver2.log
/usr/bin/vncserver :2 -geometry 800x600 2>&1 > /tmp.vncserver3.log

Then post the contents of the log files.

I think the vnc-http-1 service is for java connections through a browser.

Yeah....what Dave said.....

Woa! that was fast!

thanks for your reply

only log 1 has a 50 byte size after a reboot. here's what I get:

[root@gdgate /]# cat ./tmp.vncserver1.log
Starting VNC server: [ OK ]

now explain that:

Code:

[root@gdgate /]# nmap localhost

go figure...

What about adding a few pauses:
sleep 30
/etc/init.d/vncserver start
sleep 30
/usr/bin/vncserver :1 -geometry 1280x1024
sleep 30
/usr/bin/vncserver :2 -geometry 800x600

This will put 30 second pauses to let the previous command run for a while. Try it with the long pauses just for testing purposes although it will slow your boot down by 1 1/2 minutes.

Anyone know how to run vnc server without actually logging in on boot time?
