picoFirewall is a firewall for Linux, which reliably protects your personal PC or your server. picofirewall runs on Debian Linux, SuSE and other Linux distributions.

It's official home is on http://www.seismo.ethz.ch/linux/picofirewall.html

picofirewall is designed to reliably protect your machine with no or minimal configuration. In addition, it was designed to keep your log-file small, but yet logging all interesting packets arriving at your machine.

The rather complicated log-file created by iptables may be viewed easily on a web-page in a nice HTML-format, if the package picoFirescan is installed; see http://www.seismo.ethz.ch/linux/picofirescan.html
