Yeah, removing as many points of failure in your notification system is better. Having a GSM modem hooked up to your monitoring machine directly removes one point of the failure, the Internet. Yes, you still rely on the mobile network being up but: probability(cellularfailure) < probability(cellularfailure) + probability(internetfailure) . Has the added benefit that you can notify by SMS if your internet link goes down 8) We use a falcom GSM modem with a simple DB9 serial connection and smstools. Works fine and the GSM modems are quite inexpensive (it was somewhere around $400 a few years back IIRC). _______________________________________________ Slugnet mailing list [email protected] http://www.lugs.org.sg/mailman/listinfo/slugnet
