pf2x is a PHP script that will take the output of your pflog and convert it into various different output formats. These output formats include plain text, XML, HTML, PDF, and MySQL INSERT statements for import into a MySQL database. This was developed and tested on OpenBSD 3.3 but should work for any system that uses PF.
pfSense is a m0n0wall-derived operating system platform with radically different goals, such as using Packet Filter, FreeBSD 6.x (or DragonFly BSD when ALTQ and CARP is finished) ALTQ for excellent packet queueing, and an integrated package management system for extending the environment with new features.
pfflowd is a small daemon which converts real-time state expiry messages from OpenBSD's PF packet filter into Cisco NetFlow datagrams. This allows very fine- grained traffic accounting in conjunction with NetFlow capable tools and places almost no incremental load on a PF firewall.
pflogx is a simple tool that exports OpenBSD packet filter logs to XML files. It reads a binary log file generated by the pf logging daemon (pflogd) and generates a human-readable and exploitable XML file. Using an XSLT processor you can convert this XML file to any other format, such as HTML, CSV, or SQL.
pks-commands.php3 allows your Web server to search and add PGP/GPG keys from the public keys out there. It takes the TCP 11371 port connection and does it all on the web server. It is good in environments where the client machines are unable to get to arbitrary TCP ports (such as behind tightened firewalls).
plugdaemon is a load-balancing "plug" proxy. It allows you to forward TCP connections to one or multiple hosts, using load balancing or failover, and to route the connections through an HTTPS proxy. Access control is done by source interface or by originating IP. Outgoing connections can be bound to a specific IP address.
