introduction

Wireshark is a free packet sniffer computer application. It is used for
network troubleshooting, analysis, software and communications protocol
development, and education. In June 2006 the project was renamed from
Ethereal due to trademark issues. The functionality Wireshark provides is
very similar to tcpdump, but it has a graphical front-end, and many more
information sorting and filtering options. It allows the user to see all
traffic being passed over the network (usually an Ethernet network but
support is being added for others) by putting the network interface
into promiscuous mode.
