Hi,
There's a linux cluster somewhere (using Rocks), and I use remote
desktop (nxmachine) to do the work on the frontend of the cluster. The
desktop is Gnome. And, I intend to install new nVidia driver, but it
requires me to stop the X Server. I check around the internet, they say
we can use the /etc/init.d/gdm stop, but I can't run it since the gdm
file does not exist. Another alternative is by rebooting the Linux (of
course, we change the inittab before). But I don't know how to reboot
remotely. Moreover, I don't know if it is safe to reboot Linux remotely,
because I
can't physically access the linux workstation. Oh, the operating
system of the Linux is CentOS 4.
What should I do ?
Thanks.

If you ran services (the gui) and checked that all services were set to run on level 3 and 5, would the cluster stay up and you reconnect back in with ssh to complete the install? I'm clueless about a cluster. :) Ric -- ---------------------------------------------------- My father, Victor Moore (Vic) used to say: "There are two Great Sins in the world... ..the Sin of Ignorance, and the Sin of Stupidity.

Beside it's not going to make your NX Client session any much faster Also to it does not have to be in run level 5 to access it with NX. Hint: If that's what you really want then enter runlevel 3 (# init 3). Then start the driver install, but you may very well be asking for a Night Mare doing this to a Cluster. Be warned if the cluster OS runs off a san server as well as all the cluster nodes it could be trouble, (Diskless).
