Ethereal

Ethereal is a network protocol analyzer for Unix. It allows you to examine data from a live network or from a capture file on disk. You can interactively browse the capture data, viewing summary and detail information for each packet. Ethereal has several powerful features, including a rich display filter language and the ability to view the ASCII contents of a TCP connection.

Netlog

An advanced network sniffer system to monitor your networks. These programs are a part of the network security system used by Texas A&M University. It can be used for locating suspicious network traffic. The following programs are included: tcplogger - Log all TCP connections on a subnet udplogger - Log all UDP sessions on a subnet extract - Process log files created by tcplogger or udplogger All three programs require an ANSI C compiler. Tcplogger and udplogger use the SunOS 4.x Network Interface Tap (NIT).

tcpdump

The tcpdump program by Van Jacobson. This program is similar to Sun's etherfind, but somewhat more powerful and slightly easier to use. It captures packets from an Ethernet in promiscuous mode, and displays their contents. Numerous options exist to filter the output down to only those packets of interest. This version runs on a number of different UNIX platforms.
