Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Originally named Ethereal, in May 2006 the project was renamed Wireshark due to trademark issues.
We would like to join the team of Wireshark praisers, but we find it extremely unnecessary. There is not much we can add while reviewing a software that is, to put it in simple words, the standard of its industry. And that’s what it is. Wireshark, a powerful and fully-featured packet-sniffer and network-analyzer is simply what the pro guys keep using, when it is about network analysis and some other obscure hacking tasks.
Wireshark, which can be used for a very wide range of purposes, is a wonderful software that lets you inspect every packet transiting on your network, giving incredible insights and didactic materials to the ones who are trying to purse a career as security specialists or Internet thugs. Don’t be scared, it is not that hard to use Wireshark, and for the ones who really want to dig, Wireshark provides, on its website, full documentation of all the features that this amazing piece of software is able to offer. Wireshark, realizing unlike many other softwares of this particular field that we are in 2012 and that the terminal is a no-no for many people, offers also a GTK interface, letting you use this powerful tool even from your favorite GUI.
Wireshark comes under the terms of GPL and can be freely modified and redistributed.
Wireshark, previously known as Ethereal, is one of the most successful softwares of the Free Software world and can be installed from the Ubuntu Software Center, simply searching “Wireshark” and clicking on “Install”. You can also install Wireshark from Synaptic Package Manager or by opening a terminal and typing:
sudo apt-get install wireshark
