TCP stream/UDP/IP payload ‘grep’ utility

flowgrep is a basic IDS/IPS tool written in python as a way to help you investigate and manage your network. it works by sniffing traffic, reassembling TCP streams, and IP and UDP fragments into single packets, and allowing you to “grep” through their payloads using regular expressions. the quality of the regular expression engine is similar to Perl’s. think of it as a marriage of tcpflow, tcpkill, and ngrep.
