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 ?
"init 3"? 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
