Net::LibNIDS version 0.14
=========================

This module embeds the libnids C library written by Rafal Wojtczuk
<[email protected]>. libnids is designed to do all lowlevel network code
required by a network intrusion detection system (whichis what NIDS stands
for). This module uses libnids to allow you to read the reassembled tcp stream
without any duplicates or incorrect order. That is, like a normal host would
have seen the stream.

Note that on AMD64 architecture machines the libnids library must not be
compiled with strict aliasing enabled.  For GCC, this means passing
-fno-strict-aliasing if you use -O2 or above.  Alternatively compile with -O1.

Tests will fail if libnids is compiled with -O2 but this is not a bug with
Net::LibNIDS, as no callbacks are raised by libnids.  See:
