Sun Ray's and VNC

[coffeysm]

I figured I would post this in case anyone else might find it helpful. I been wanting to be able to access my user's sessions remotely and managed to get VNC to do it for me. I downloaded RealVNC 4.1.2. I installed it in /usr/local/bin and created the password file under /usr/local/etc/vnc/passwd. I then added the following to my /etc/dt/config/Xsession.d/login.sh, which is a script I have that runs whenever a user logs in.

VNCDISPLAY=`who | grep dtlocal | grep $USER | awk '{print $6}' | sed 's/[()]//g'`
VNCPORT=`echo $VNCDISPLAY | sed 's/://g'`
if [ "${VNCPORT}" -lt "9" ] ; then
    VNCPORT=0${VNCPORT}
fi
/usr/local/bin/x0vncserver -rfbport 59$VNCPORT -display $VNCDISPLAY -PasswordFile /usr/local/etc/vnc/passwd &

Probably not the greatest security practice in the world, but I made the passwd file 640 and set x0vncserver with a guid.

Now if someone is having a problem I run another script that connects up automatically and I can see what they are doing.

/usr/local/bin/vncviewer -FullColor -PasswordFile /usr/local/vnc/passwd servername:display

I bet your sunray servers love all these vnc sessions running.
Have you tested the performance impact on the servers from doing this ?

we used that type of setup at my last job, as a way to remotely support users. It did not impact the servers. In my experience with Sunrays, the biggest problem we had was everyday user apps such as mozilla/star office. talk about resource hogs, get 70+ users on one sunray running those apps, then you'd see some degredation in performance

Yes I know what you mean about mozilla/staroffice, thats why I asked about the performance impact, try running 200+ users on a v440 sunray server, thats what I had to deal with at my last job...

It has little to no impact on my server performance. I also setup two servers in a failover/load balancing group; to help if they should start getting hammered. Most of our user's remote into a MS Terminal Server anyway and run all their apps.
