What is Hsns?
hsns is a packet sniffer for unicies written totally
in Haskell ( Currently, hsns 
has only been tested to work on Linux. 

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

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'
[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.


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

	-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.
