tcpdump is a data-network packet analyzer computer program that runs under a command line interface. It allows the user to display TCP/IP and other packets being transmitted or received over a network to which the computer is attached.[3] Distributed under the BSD license,[4] tcpdump is free software.
Tcpdump works on most Unix-like operating systems: Linux, Solaris, FreeBSD, DragonFly BSD, NetBSD, OpenBSD, OpenWrt, macOS, HP-UX 11i, and AIX. In those systems, tcpdump uses the libpcap library to capture packets. The port of tcpdump for Windows is called WinDump; it uses WinPcap, the Windows version of libpcap.
Esta herramienta nos va a permitir ver información sobre el tráfico que entra y sale de una interfaz de red determinada. Se trata de una herramienta de diagnóstico que nos va a permitir ver la información de los paquetes. Esta información será de donde provienen los paquetes entrantes y hacia donde se dirigen los paquetes salientes, aportando algo de información adicional. Incluso podremos guardar el resultado en un archivo para echarle un vistazo en otro momento.
