Wireshark is a free and open-source packet analyzer. This tool is used for network troubleshooting, analysis,
communication and software protocol development and education. The original software were named Ehtereal, in May 2006.
Later it was renamed to Wireshark due to trademark issues.
Wireshark uses pcap to capture packets. It runs on several platforms like GNU/Linux, OS X, BSD, Solaris,
some other Unix-like operating systems, and Microsoft Windows.
There is also a terminal-based version (non-GUI) called TShark.
Here I’d like to introduce some important filter options in wireshark.
It’s very hard to find exactly the right packets, you are looking for, in a hugh amount of data.
The following charts are a compendium of several websites.
My aim for these post was, to bring the most important commands of one page.
