Use Modem to Call Phone Number
I've been having some issues with two of our linux servers (they just mysteriously stop responding at random times - brand new, have tried replacing all the parts). Anyway, I think I have the problem fixed, but it has brought up an interesting problem: I don't know when they go down. We have some modems that we've salvaged from various operations, and I'd like to know if there is a way to use one of said modems (or just buy a new one - external of course) to call me when I run a command (i.e. if the server doesn't respond to a ping for over 30 seconds, call me). I was assuming that mgetty/vgetty could do that, but I didn't find any hard evidence saying it could. Any thoughts on this? And on a side note, any modems that are particularly recommended?
