MacSniffer

Version: 1.0 beta || Release Date: 2007-06-23 || License: Freeware Developer: Brian Hill | App Owner: bug

MacSniffer is a front end to the built-in 'tcpdump' packet sniffer on Mac OS X. MacSniffer allows you to view all of the traffic on a network connection, such as ethernet.

MacSniffer includes a filter editing interface and a filter library to easily construct and reuse packet filters to view a subset of all the traffic on the connection, such as just that destined for a specific host or port.

You can choose the level of detail you want captured, from just the minimal packet headers (showing source and destination hosts and ports) up to a full hex and ASCII dump of the packet contents.

MacSniffer can be useful for diagnosing many network problems, debugging client/server programs, and scanning for particular network exploits in real time.

The "about" for this program says Copyright 2001 Brian R. Hill. Is this program really really old, or has the guy been working on it for a looong time, or what?

Not freeware. It's only free while in beta, after which period it costs $15.

Like the idea of this, but no matter what ethernet interface I select, it doesn't show any output (using default settings and pressing "start"). And yes I did an ifconfig on the command line to check what the Airport interface ID was (en1) to make sure I was selecting the right one in MacSniffer preferences.
