Solution:

[svraman@adc2201664 bin]$ echo $DISPLAY

[svraman@adc2201664 bin]$ 1.0

[svraman@adc2201664 bin]$ setenv DISPLAY adc2201664:1

I have used the vncserver to connect to the remote m/c.

[svraman@adc2201664 bin]$ xhost +

access control disabled, clients can connect from any host

[svraman@adc2201664 bin]$ sudo ./rcu
