I figure this is probably something I would have to script myself because I can't find anything useful looking out there, but I thought I'd ask before I try (or perhaps before I procrastinate again):

I have a machine here at home running some 24x5 programs which I really
need to keep up and running, along with my broadband so it can get its
datafeeds.

I figured I could run a program on my webserver to ping my home machine
regularly and in case it starts to slow down, lose packets or die
completely, it could send me an SMS to alert me to the fact.

Is there something like this already in existence?
Not sure as I'm going from memory. Webmin had/has a heartbeat monitor plug-in and if memory serves it had a way to notify a phone number, e-mail address etc. I assume it's not that important to be SMS necessarily?

Webmin AFAIK is not in Debian anymore; but you can get it upstream or perhaps look at the heartbeat application in Debian to see what it has for remote notification.

Isn't this what SNMP was designed for?

There was probably a lot more that it was designed for. Plus one of the first things to appear in google:

"Despite its acronym, SNMP is not exactly simple! In fact, it never ceases to amaze me how much of a black art implementing and using SNMP"

I don't necessarily want to avoid it, it's just got that 'can-of-worms' sort of feel to it and I'm hoping I only need the little script in bash. Or at least I did until I realised I'd have to tie ping together with dyndns.org and smsclient. Possibly a brainer. I mean, not a no-brainer.
