Does anyone know of a way to send SMS messages without an internet connection?

Having a network monitoring system send sms pages via email very quickly runs into chicken-egg scenario. How do you email a page to let the admins know their net has gone down. :-P

AT&T shut down their TAP dialup late last year.

The only method that comes to mind is to buy a GSM modem which has SMS messaging capability.

Has anyone done this?

We use a standard modem and pestered Alltel until they gave us the secret modem->SMS gateway number.

Nagios includes /usr/local/bin/sms_client. Fairly simple to use:

Usage: sms_client -v sms_client -d sms_client [-q][-l loglevel] [service:]number|name[,name|[service:]number...] [message] ...

As long as the monitoring server and the phone lines are working it works great.

Nagios is configured to use sms_client: http://www.smsclient.org/ Works great other than being a royal pain in the rear when a lot of things go down and dependencies are not set up in Nagios... I'll fix that one of these days :-) Mark Radabaugh Amplex
