Recently I started to play with scapy – a powerful interactive packet manipulation and custom packet generation program written using Python. Please note that this tool is not for a new Linux / UNIX users. This tool requires extensive knowledge of network protocols, packets, layers and other hardcore networking concepts. This tool is extermly useful for
a] Understanding network headers
b] Testing network security
c] Write your own utilities using scapy
d] Decoding protocols etc
From the man page:
You can use this tool to check the security of your own network as it allows to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more. It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery. It also performs very well at a lot of other specific tasks that most other tools can’t handle, like sending invalid frames, injecting your own 802.11 frames, combining technics such as VLAN hopping+ARP cache poisoning, VOIP decoding on WEP encrypted channel, etc.
