Reduce your admin workload with cluster ssh

Clusterssh (cssh) is designed to basically do the same commands in multiple windows, each can be a different machine. This works very well for clusters where everything should be the same. Also it means you basically need the same config files on both, so you can use the same keystrokes to edit the same file on different machines. It makes you think about having the exact same config files on both machines, which is a good thing. Say on a web frontend, the config files should match exactly, and the software should take care of the load balancing and declaring hosts dead.
