![]() ![]() Wireshark Tutorial INTRODUCTION The purpose of this document is to introduce the packet sniffer Wireshark. Check out our recommended Wireshark training books and study guides. It’s a tool that is used to inspect data passing through a network interface which could be your ethernet, LAN and WiFi. ![]() Wireshark is a very powerful and popular network analyzer for Windows, Mac and Linux. If you run Wireshark as a normal user, you won’t be able to use any network interfaces for capturing, because of the default Unix file permission that network interfaces have. The aim of this article then is to supply a comprehensive introduction to TCP/IP to enable you to come to useful conclusions about the network traffic data you’re analysing. To help the beginner understand Wireshark they will need to understand network traffic. You may ask what makes Wireshark different to other network analysers – apart from the fact that it’s free – and why we’re not simply advocating using tcpdump for packet capturing? The main advantage of Wireshark is that it’s a graphical application.Ĭapturing and inspecting network traffic using a graphical user interface is a very helpful thing because it cuts through the complexity of network data. Your Linux distribution will have a ready to install package for analyser too, so go ahead and install it. Nowadays, most people use Wireshark and Ethereal has been consigned to history. ![]() Wireshark was born in June 2006 when Combs renamed the network tool Ethereal, which he also created, as he was changing jobs and couldn’t use the old name anymore.
