Description:

ngrep strives to provide most of GNU grep's common features, applying them to
the network layer. ngrep is a pcap-aware tool that will allow you to specify
extended regular or hexadecimal expressions to match against data payloads of
packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw across
Ethernet, PPP, SLIP, FDDI, Token Ring and null interfaces, and understands BPF
filter logic in the same fashion as more common packet sniffing tools, such as
tcpdump and snoop.

First, lets look at installing it. I'm not much of a writer so I will just show
the commands used throughout most of this tutorial.
