Ipmon extensions

Dear FreeBSD Ipfilter users,

As a part of a recent project we developed some extensions to IPFilter to
allow http sessions to be remotely monitored using ipfilter boxes. Since
they were quite useful in our case and have been working without problems
for a few months, I thought some other users might be interested in using
them. These extensions consist in a set of patches for FreeBSD 5.4 (IPFilter
3.4.35) and 6.1 (IPFilter 4.1.8) and provide the following services:
- Export ipmon information (packets, states and NAT logs) through the IPFIX
protocol to an ipfix collector.
- Monitor HTTP sessions (rather than TCP connections) when they do not use
pipelining.

The ipfix protocol part mostly comes from the Vermont (vermont.berlios.de)
project.

Patches can be downloaded here:

Best regards,
