Softwares: WireShark – Ultimate network Sniffer | BHS

Wireshark is the world's foremost network protocol analyzer, and is the de facto (and often de jure) standard across many industries and educational institutions. It is used for network troubleshooting, analysis, software and communications,protocol
development, and education. You can interactively browse the capture data and view summary and detail information for each packet. Wireshark has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session.

Wireshark was written by networking experts
around the world, and is an example of the power of
open source. It runs on Windows, Linux, UNIX, and other platforms.

Wireshark can read live data from Ethernet, Token-
Ring, FDDI, serial (PPP and SLIP) (if the OS on which it's running allows Wireshark to do so), 802.11 wireless LAN (if the OS on which it's running allows Wireshark to do so) and ATM connections (if the OS on which it's running allows Wireshark to do so). Wireshark was previously known as Ethereal.

The name might be new, but the software is the same. Wireshark's powerful features make it the tool of choice for network troubleshooting, protocol
development, and education worldwide.
