ngrep freeware - The Latest Versions History
1.45 Nov 18, 2006 New 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.
