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 understands many kinds of protocols, including IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw, across a wide variety of interface types, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.
Key Features
- Basic Packet Sniffing.
- Debug HTTP interactions.
- Process PCAP dump files looking for patterns.
- Observing binary being transferred across the wire.
