Scenario 3:

PROBLEM:

On a reboot of GCEMS server the vncserver process does not restart automatically.

SOLUTION:

For security reasons VNCserver does not restart on a reboot of the GCEMS

server. However if your network is secure you can follow the next few steps

and configure vncserver to restart after a reboot of GCEMS server.

Open a terminal on GCEMS and go to /etc/sysconfig

Using a text editor, edit the vncservers file as shown below:

Uncomment the line VNCSERVERS="1:myusername"

ii.

Change the line in previous step to VNCSERVERS="1:excelsw"

iii.

Save and close

iv.

Enter the following command to edit the runlevel

$/sbin/chkconfig vncserver on

Verify that runlevels 3 4 and 5 are all on by entering the following command

$/sbin/chkconfig vncserver --list

vncserver 0:off 1:off 2:on 3:on 4:on 5:on 6:off

vi.

vncserver will now start on a reboot of GCEMS
