WireShark 1.4.3

[Fed0t]

WireShark is probably one of the most famous and most frequently used network sniffer. People like to call it the Network Protocol Analyzer too. Call it whatever, but, your security tool aresenal is incomplete without WireShark. It was previously called as Ethereal.

Also, it is open source. It is cross platform and it has been in development for more than 10 years now! It also appears in the TOP 100 tools on SecTools. This application is very similar to TCPDump in its working, but it has better sorting & grouping actions. It also has a GUI, which TCPDump lacks. It allows the user to see all traffic being passed over the network. It uses pcap & WinPcap where applicable to capture packets.

Here is the starting introduction video for newbies
