(a)
is an application layer protocol defined by the Internet Architecture Board in RFC 1157.
(a)
It is a network protocol analyzer, or an application that captures packets from a network connection, such as from your computer to your home office or the internet.
(a)
Wireshark listens to a network connection in real time and then grabs entire streams of traffic – quite possibly tens of thousands of packets at a time.
(a)
Wireshark is capable of slicing and dicing all of this random live data using filters. By applying a filter, you can obtain just the information you need to see.
(a)
Wireshark, like any good packet sniffer, allows you to dive right into the very middle of a network packet. It also allows you to visualize entire conversations and network streams.
