What is Hsns?
=============
hsns is a packet sniffer for unicies written totally
in Haskell (http://www.haskell.org) Currently, hsns 
has only been tested to work on Linux. 


Installation
============
To install, you need to have a haskell compiler such as the
Glasgow Haskell Compiler installed, the Pcap library to be
installed, and the Network.Pcap libraries for GHC.
You may obtain Network.Pcap from http://hackage.haskell.org

To install, run the Setup.lhs script like so (you can skip
the chmod part if you have pulled hsns from the darcs
repository with the --set-scripts-executable flag):

[austin@continuum hsns]$ chmod +x ./Setup.lhs
[austin@continuum hsns]$ ./Setup.lhs configure
...
[austin@continuum hsns]$ ./Setup.lhs build
...
[austin@continuum hsns]$ su -c './Setup.lhs install'
Password: 
...
[austin@continuum hsns]$ 

hsns is now installed.


Packet filters
==============
hsns can receive a berkeley packet filter
in it's command line (anywhere) that can
be used to filter packets in the same style
as Tcpdump. For a reference on bpf's, see the
tcpdump man page.


Options
=======

Currently, hsns accepts the following options:

	-h,-?	  --help		Display help

	-c[COUNT] --count=COUNT    	Exit after receiving COUNT packets.
				   	0 is receive forever, default is 5.

	-D	  --iflist	   	List interfaces that can be captured
				   	on

	-i INT    --interface=INT    	Listen on interface INT.
					
	-l        --linebuffered	Make output line buffered.

	-p        --nopromiscuous	Do not go into promiscuous mode
	
	-s LEN	  --snarf=LEN		change snarf length from 68 (default)
					to LEN.

	-V	  --version		Display version and exit.
