Free and open source pcap-aware tool for your Mac. #Specify expression #Data packet #Hexadecimal expression #Specify #Specification #Expression
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.
ngrep currently recognizes TCP, UDP, IPv4/6, IGMP and Raw across Ethernet, PPP, ICMPv4/6, SLIP, FDDI, Token Ring and null interfaces, and understands BPF filter logic as more common packet sniffing tools, such as tcpdump and snoop.
What's new in ngrep 1.45:
- fixed bug bug where setting the snaplen smaller than the minimum necessary to read full headers would cause garbage to be fed into the pattern matcher
- fixed unreported bug in IPv6/TCP packet length calculation
- relocated the privilege-dropping routine to be invoked right before entering the packet processing loop, to prevent interference with necessary permissions to read or write dumpfiles/etc.
- fixed integer overflow with the snaplen that resulted from an implicit signed/unsigned conversion
