Installation Wireshark on Ubuntu

Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. It is a very good helper of a network administrator and it rescued my network many times. You can install it on Ubuntu by running following commands in terminal:

sudo add-apt-repository ppa:n-muench/programs-ppa
sudo apt-get update
sudo apt-get install wireshark
