Firewall Improvements From R. Scott Smith

In response to my article about using the recent IPTables module to fight brute-force password attacks, based on an idea from Andrew Pollock, a reader worked out the idea into a complete firewall script, with configurable whitelisting, the ability to block multiple ports, and several other enhancements. Read his post for the details.

You can download his firewall script here. You can contact the author at the address meetscott at the domain netscape.net.
