Wireshark 1.8.6

WireShark is a tool for monitoring and capturing network traffic.

It is able to capture selected network protocol's traffic and view or save it as a text file. Captured packets may be filtered by IP-addresses, port or by the message contents.

WireShark supports multiple protocols such as TCP, UDP, IEEE 802.11, Bluetooth and USB-packets. It can also decrypt a crypted protocol traffic.
