Fail2ban has a email alert system built in (long as mailx is installed)
which not only gives you IP but also does a whois lookup and cats that
to the email. I've used that with procmail to graph offending host IPs
by location. Mostly for giggles, but it's interesting to see the large
majority (80+%) come from Chinese IPs.
