free NX port configuration

Problem: nxagent uses ports from 7000 so when second user logs in it take port 7001 which is used by WebLogic.

Resolution: By default freenx uses DISPLAY_BASE + 6000 = 7000 port.
To change this you need to modify the following parameters in /etc/nxserver/node.conf file.

#16000 base port will be used
DISPLAY_BASE=10000

Then restart nx server with:

nxserver --restart
