Hello all.   I've got two Red Hat Linux servers, one's a file server, the other a route/internet server. I've got an APC smart-UPS 1000. The UPS sends a shutdown signal to the file server via a serial cable. You can *$buy$*! an Interface Expander to get two serial ports out of the UPS, but isn't good old Linux capable of much more than the usual buy-buy-buy.    What I want to attempt to do is to get the server which is connected to the UPS, when powering down, to send the other server a poweroff/run-level 6 signal via the lan.   Is this possible?   What proceedure would I use, and where would I find the relevent info?   Is writing a shell script on the right track, or doesn't this work over the lan?   Reguards, Trevor.
