What is derrick

Derrick is a simple tool for recording data streams of TCP and UDP traffic. It shares similarities with other network recorders, such as tcpflow and wireshark, where it is more advanced than the first and clearly inferior to the latter. Derrick has been specifically designed to monitor application-layer communication. In contrast to other tools the application data is logged in a line-based ASCII format. Common UNIX tools, such as grep, sed & awk, can be directly applied. Even replay of recorded communication is straight forward using netcat. Derrick supports on-the-fly compression and rotation of log files. The payloads of TCP sessions are re-assembled using Libnids and can be merged or truncated. UDP payloads are logged as-is. Details of lower network layers are omitted.
