ethereal and wireshark
Another very usefully tool from the open-source community is the program ethereal/wireshark.
Please don’t be confused about those two names. It is really the same software, only in different
versions. Formerly, the program was called “ethereal”, but due to some legal restrictions it now
uses the name “wireshark”. Full documentation, the latest version and more is available at
http://www.wireshark.org. If you try to use it on an HP-UX system, you should use the depots
from http://software.hp.com, under “Security and manageability”, HPUX Internet Express for
HP-UX.
You can use ethereal/wireshark as a trace tool. It is a very strong tool for formatting, analyzing
and interpreting network traces. Using ethereal/wireshark is the simplest way to analyze a
network trace.
The tool is always capable of opening the network trace files created with nettl or tcpdump,
regardless of the platform it is installed on (HP-UX, Windows, Linux…). It is a strong protocol
analyzer, contains a lot of easy to use filter function, and also gives you statistical information
for performance discussions. As you could expect from such a graphical tool, you will find a
voluminous online help.
