ADSL Uptime Script

[LethalChicken]

Ok so this is not exactly 100% adsl related question but I'm looking for a script I can put on my server (linux box) at work to check every x minutes if my connection (server sitting at home on ADSL link) is still up.

I have googled for something like that but with no luck ...

I'm looking for something like www.alertra.com does ... but on my own server

I can think of a multitude of innovative, yet easy ways,
a dynamic dns running on adsl account and a ping running in a crontask on the linux box at work,
or, even easier,
run a messenger on both computers, and watch when the contact goes offline

I need a linux script option ...

<blockquote id="quote"><font size="1" face="Verdana, Arial, Helvetica" id="quote">quote:<hr height="1" noshade id="quote">
#!/bin/bash

host="google.com"
email="[email protected]"

ping_result=`ping -c 1 $host 2&gt;&1 | grep "icmp_seq"` &gt; /dev/null
if [ "$ping_result" ] ; then
echo "Host $host is up"
else
echo "Host $host is down" | mail -s "Host Down" $email
fi

ok and then just cron it for every 5 minutes or so ... not a bad plan .. txs []

just remembered about smokeping, you might find it will do exactly what you need, as well graph the latency and uptime!
