What is Ethereal?
Ethereal is a program developed by Gerald Combs and the Wireshark Team, whose primary function is to enable users to analyze data packets. Also known as a network or protocol analyzer, the software is more commonly known now as Wireshark.
The program allows for troubleshooting of network issues, where data packets are intercepted and then captured to provide the user, generally a network administrator, to analyze data flow between the host computer and its network of computers, or between a computer and an IP network.
Basically, what the program does is to interpret data stream as data packets, from which the user can navigate through all the layers within the packet for a thorough analysis of data exchange between networks.
Ethereal was developed for the following computer systems: UNIX, Mac OS X, Linux, Windows ME, Windows 98, Windows Server 2003, Windows XP, Windows 2000 and Windows NT 4.0. It can recognize up to 750 protocols. Data packet capture can be launched from the Capture option on the user interface. Under this option, the user can click on the Start link to begin the capturing process.
