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.

 

remote ssh forwarding

for some reason I always forget the syntax to forward a port on my server to my local system to work remotely from home on some of my webapps.

Now to not forget it again, I shall write it down on my blog, so I can just look at it...


ssh -L port:remoteServer:port remoteServer


now this let's me access the 'port' on my 'remoteServer' on my local system and work on the webapp. Now I just have to rewrite all the absolute paths to relative paths, so that I can find my css stylesheets too...
