Reapoff (Regular Expression, Arbitrary Protocol, Opensource Filtering Firewall) is a regular expression enabled TCP/IP proxy. It operates on data using a pair of simple rule- based configuration files defining the tests and actions to perform on data. It can also sign SSL connections transparently (with MITM), applying a security policy to encrypted SSL sessions that would otherwise be allowed unchecked. The proxy forms the core part of an overall firewall solution designed to run from a RAM disk using Trinux.
flashboot for OpenBSD is a set of makefiles, scripts, and support tools to build an OpenBSD image suitable for booting from read-only media, such as flash memory.

This image may be further trimmed or extended by editing the packing list files included in the distribution.
