iptables filtering. As the name implies, *ban2fail* was inspired by the popular
*fail2ban* project (http://fail2ban.org).
*ban2fail* started with a few hours of C hacking after my mail server was
exploited to deliver spam for others who had cracked a user's SMTP send password.
After inspecting the log files I realized that crackers are now using widely
distributed attacks, and that I would need an app that could run several times a
minute on my rather modest Linode virtual server to have a chance of stopping
them. I hope you find this code useful.
