Network Grep Description
Free and open source pcap-aware tool for your Mac Network Grep strives to provide most of GNU grep's common features, applying them to the network layer. Network Grep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. Network Grep 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 in the same fashion as more common packet sniffing tools, such as tcpdump and snoNOTE: Network Grep is licensed and distributed under the terms of the Other/Proprietary License. What's New in This Release: · 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 · minor change to compensate for some broken compiler optimizers · fixed double-free race condition during ngrep termination · reworked packet length calculation in the main processing loop, improving performance and readability · simplified regex build logic in configure and Makefile · updated Win32 version to use config.h for preprocessor definitions instead of the Visual Studio project files, making manual tweaking and config of ngrep for Win32 consistent with *NIX and more obvious · changed third-party Makefiles to properly clean up after themselves · added support for radiotap (IEEE802_11_RADIO) · changed ``-s 0'' invocation to mimic the equivalent of tcpdump
