There's a program in Fedora 9 (and probably in other distros too) called Specto, which occasionally checks websites, and notifies you if they've changed since last time it checked.

I would guess I am not the only person on the planet who doesn’t have time to regularly check their website for defacement and was wondering if any experienced ALUGers could recommend a ready made script which I could run on my home server which would enable me to compare my live website (on a remote commercial webhost) with a stored image of it (on my local server) a couple of times a day.

Do other ALUGers bother to check their own websites for defacement regularly? If so what tools do you use?

I'd just cron a script like the following:

--- Begin Script --- #!/bin/bash

site=http://www.sommitrealweird.co.uk/ md5sumfile=/home/brettp/.sommitrealweird.md5

# First run, just setup the file if [ ! -e "$md5sumfile" ]; then dog --no-header "$site" | md5sum > $md5sumfile exit 0 fi

echo $(< "$md5sumfile") echo $(dog --no-header "$site" | md5sum)

if [ "x$(dog --no-header "$site" | md5sum)" != "x$(< $md5sumfile)" ]; then echo "Page changed" exit 1 fi --- End Script ---

That was just knocked up as an example, but it does work ;)

dog is cat + http and ftp and various things, it's really quite handy to have knocking about, apt-get install dog!
