Tripwire and Spong are two programs that can do things such as this.
However, if you only want to monitor /etc/passwd and /etc/shadow, it
might be easier to write a small script that md5sum's each file and
compares it to the `correct' md5sum that you generate by hand. Run
the script in cron and have it send an email out if the checksums
don't match.
