Kirk,
Pingdom (http://pingdom.com) is a pay service, but they "also offer a
free account that lets you monitor one website and includes 20 SMS
alerts."
I use it for monitoring my personal web server (via ICMP) and it works
wonderfully.

Re: [BLUG] Bad Weather? Geek Play Time
Actually, the weather is pretty clear where I am, and I'm fixin' to spend the lunar new year with Chinese friends. I'm in Shanghai, so... :D
I have lot's of friends and family stormed in doors there in Indiana, so best wishes to you!

Re: [BLUG] Bad Weather? Geek Play Time
IIRC, ping is pretty easy to script. It supports a -c option to ping a certain number of times, and the return code is an indicator of success.
This means you should be able to do something like:
while true ; do
if ! ping -c 1 $YOURHOST > /dev/null ; then
mail -s "host $YOURHOST is down" $YOUREMAIL << /dev/null
fi
done
This was just off the top of my head. YMMV. I've not double-checked man pages or tried running it.
I don't know about people with free time due to the weather. I mean, if we work with computers we can keep working as long as the power is up and if the power is down it means it is time to start eating the contents of the fridge...
Cheers,
Steven Black

Re: [BLUG] Bad Weather? Geek Play Time
If you have something to ping, I can setup a nagios check that can
email you if it goes out. I find that a cheap solution is to give a
print server or an extra broadband router and IP address that your
external router forwards icmp too. Then don't put that device on a UPS
and that should give you a good idea of if the power is out.

I actually have a domain bloomingtonnetworks.com that I was working on
setting up for this kind of thing. I don't have a public side to that
yet, but its already monitoring Suso, IU, City Govt., Smithville, Kiva, etc.

Re: [BLUG] Bad Weather? Geek Play Time
You could use "positive verification" by having a system mail you
every hour or 30 minutes that every thing's ok, but that gets annoying.

I have a personal system that emails me each time it powers on so I
know if it's been rebooted, but that only works because it is more
likely to be rebooted than just powered off.
