Tcpdump is the network sniffer we all used before (Wireshark) came on the scene, and many of us continue to use it frequently. It may not have the bells and whistles (such as a pretty GUI and parsing logic for hundreds of application protocols) that Wireshark has, but it does the job well and with less security risk. It also requires fewer system resources. While Tcpdump doesn't receive new features often, it is actively maintained to fix bugs and portability problems. It is great for tracking down network problems or monitoring activity. There is a separate Windows port named WinDump. tcpdump is the source of the Libpcap/WinPcap packet capture library, which is used by Nmap and many other tools.
