If you want to monitor changes to the passwd/shadow file, one way would be to write an ext script. One can get around the OS recording changes to users by just editing the files directly, so this would be a bit more foolproof.
You'd need be to keep a copy of the passwd file somewhere else (say the xymon server itself) and then do a diff against it. Something like:
if scp $server:/etc/passwd $BBHOME/secret/$server.passwd.new
then
if diff $BBHOME/secret/$server.passwd.new $BBHOME/secret/$server.passwd.reference
then
COLOR=green
else
COLOR=red
fi
else
COLOR=red
fi

Yes, that's what I've done but management want a copy of them for some
reason or other...

Subject: [Xymon] Xymon Log Retrieval
Is there a doco anywhere explaining the log file retrieval mechanism?
I want to use Xymon to fetch /etc/passwd files so that I can check for unwanted/unnoticed changes.
