hsns

a miniature network sniffer

Latest on Hackage:0.5.3

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

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.
