I am looking for a packet sniffer / inspector which runs natively on OS X (Cocoa) and not with some sort of compatibility layer like X.
Ideally I am looking for an application with the following qualities:
- native (Cocoa) interface
- ability to inspect packet data
- inspect packet data as XML, or RAW formats
- free
man tcpdump. – jm666 Jun 14 '11 at 7:48
