VNC Services on Red Hat 7.3
 

How do I get VNC to start up automatically after every reboot. When I turn on the Services manually it works until I reboot.

Setup services to run on bootup
 

The Redhat command:
Hold the Alt key down, press F2
In the run dialog box that "should" popup type:
/usr/bin/redhat-config-services
It will ask for your root password.

Find vnc (or whatever service you want)
Make sure it is set to start.

There are three "run levels" to worry about:3,4,5
Level 3 is before a graphical interface starts (Set VNC to run here on 3 and on level 4, 5)

Hope this helps.
