X-Forwarding in qlogin on rocks linux > 5

to enable X forwarding from your nodes to your original remote session:

In rocks 4.3,I get the output
# qconf -sconf | grep qlogin
qlogin_command               /opt/gridengine/bin/rocks-qlogin.sh
qlogin_daemon                /usr/sbin/sshd -i
But in rocks 5.3,I get
# qconf -sconf | grep qlogin
qlogin_command               builtin
qlogin_daemon                builtin
So I changed it in rocks 5.3
# qconf -mconf global
qlogin_command               /opt/gridengine/bin/rocks-qlogin.sh
qlogin_daemon                /usr/sbin/sshd -i

And modify the script:

/opt/gridengine/bin/rocks-qlogin.sh

to include this part

/usr/bin/ssh -Y -p $PORT $HOST
The Y basically allows none secured X authentification.
