News

2008.11.30 - Hatchet-0.9.2 has been releashed. This includes the bugfix for dates (yet again... this time for real). It also includes new regex for some encapsulated traffic types.

2008.07.03 - Hatchet-0.9.1 has been released. This is a bugfix release that fixes dates stored in the database and sorting in the cgi. Delete your pflog.db before upgrading. The OpenBSD port (security/hatchet) has already been updated.

2008.06.27 - Hatchet-0.9 has been released! On top of numerous changes (see CHANGELOG), I've also rolled a port of security/hatchet for OpenBSD -current. The biggest improvements for 0.9 include the use of mod_perl to easily install Hatchet in the default OpenBSD httpd chroot; no more frames; and the removal of built-in pfstat bits.



About

Hatchet is a log parsing/presentation program written for OpenBSD's PF logs. Hatchet should be useful to the typical PF administrator who wishes to review their PF logs in a chronological order via a graphical (web) interface. Hatchet archives the logs so that you can search past events. It also allows you to sort by column, so that you may isolate traffic by source or destination address, service, rule number, etc. Additionally, it provides external links to perform DNS queries on source addresses and service quries from SANS.

Hatchet uses a series of Perl regexes to match entries from the pflog logs. The log entries are stored in a SQLite database file, allowing for highly dynamic queries and statistics. If it finds one it doesn't have a match for, it will kick off an email to the system administrator (root@localhost) with the details. It's possible to install the web interface on a separate webserver, the INSTALL document covers each task and where it should be performed. Although Hatchet uses SQLite, it does not require installation of the full SQLite "suite", only the DBD::SQLite module, which incorporates the necessary libraries.

Hopefully you find this a useful, clean log viewing utility. I plan to incorporate new features eventually, particularly more advanced reporting, but time will tell. I happily accept feature requests, but I don't intend to incorporate features that would otherwise be best handled the "OpenBSD way". In other words, I won't add a PF ruleset editor, don't ask.

Thanks for trying out Hatchet. Please email me with your feedback, compliments, etc.

Donations

Donations help me support the development and hosting of the Hatchet project. Even something as simple as $1 here and there will go a long way towards recouping my colocation costs. All donations are submitted through PayPal's secure site.

A lack of donations won't keep me from working on Hatchet, but it sure doesn't hurt. Thanks!
