+Libnids is an implementation of an E-component of Network Intrusion Detection 
+System. It emulates the IP stack of Linux 2.0.x. Libnids offers IP 
+defragmentation, TCP stream assembly and TCP port scan detection.  The most 
+valuable feature of libnids is reliability. A number of tests were conducted, 
+which proved that libnids predicts behaviour of protected Linux hosts as 
+closely as possible.  Libnids is highly configurable in run-time and offers a 
+convenient interface.  Currently it compiles on Linux, *BSD and Solaris.  
+Using libnids, one has got a convenient access to data carried by a TCP 
+stream, no matter how artfully obscured by an attacker.
+
+This requires libnet.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
