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.
