Here we use an old Hayes-alike modem on our Slackware Linux box.
It's plugged into our UPS and sitting in our racks (thus avoiding problems with power cables going walkies).
The alerts are sent by a script, which calls "sms_client", which uses "TAP"[1] to talk down a POTS line to the (in our case Vodafone) service provider (thus avoiding issues with phone reception, and also avoiding issues with not being able to send email to a mail-to-SMS gateway).

The link in there is broken, but you can get the source code from here: http://fossies.org/linux/misc/old/sms_client-2.0.8y.tar.gz/
There's what is apparently a near-definitive list of TAP Dialup Numbers here: http://avtech.com/Support/TAP/index.htm
Hope this information is of use.

Carl

Can anyone shed light on the current 'state of the art' for alerting by SMS from Xymon? Are there recommended usb-modem/software combinations to achieve this?
I'd like to have the option of sending alerts from my Xymon server without relying on email->SMS gateways. (When I need to announce that the mail queue has reached critical, it seems foolish to try to dispatch that alert by mail.)
I'm running Xymon on Solaris which will ultimately limit my options, but I'm interested in any information you have to share.
