I’m glad to have another post of Tcat Houser editor-in-chief of TRCBNews.com.

It allows the user to intercept and display TCP/IP and other packets being transmitted or received over a network to which the computer is attached. Distributed under the BSD license. The tcpdump command has a lot of advanced features, most of which revolve around filtering and finding a needle in a haystack of packets. If you run tcpdump on a remote machine, your screen will be flooded with all the ssh traffic between your client and the remote machine. To get started without having to learn too much about how tcpdump filtering works, run the following command:
