This book package offers a guide to Ethereal, a popular "packet
sniffer" security tool, for those who have never used a packet sniffer
before and for experienced users. After an introduction to network
analysis, chapters cover Ethereals network protocol analyzer,
installation, other programs packaged with Ethereal, integrating
Ethereal with other sniffers, real world packet captures, and
developing Ethereal.
Only book available on extremely popular, yet completely undocumented Open
Source security tool Ethereal. This book provides insider information
on how to optimize performance of Ethereal on enterprise networks. Book
comes with a CD containing Ethereal, Tethereal, Nessus,
Snort, ACID, Barnyard, and more! This book shows how
Ethereal compiles and runs (thanks to autoconf) on many flavors of UNIX
(including Linux), and Windows. It shows how to capture packets
from a number of different types of networking devices and also can read capture
files taken earlier using either Ethereal or other programs such as
tcpdump, snoop and various other network analyzer programs.
