#Download and install tcpdump software#

Installation of both libpcap and TCPDump is fairly straightforward as far as compiling software goes. no configure: error: see the INSTALL doc for more info Should you attempt to compile TCPDump without having libpcap installed, you'll see an error similar to the following while running the configure script for TCPDump:Д¬hecking for main in -lpcap. Both TCPDump and the PCap library can be downloaded from. Whichever method you choose for installing TCPDump, you'll also need to grab the PCap library, sometimes referred to as libpcap. TCPDump requires the PCap library, which is not usually installed on most systems.

For everyone else, you can probably search your distribution's repository for a package or just download the source and compile it, which I would recommend. The package maintenance system will install TCPDump and any prerequisites too. For example, if you're using Debian you can simply type this: Most popular Linux distributions such as SUSE also include TCPDump as an available package. TCPDump requires the PCap library libpcap, so while you're downloading TCPDump, you should download libpcap as well.
