Equipment:  Macintosh

Summary: The Snarfer is an application that directs whatever Macintosh it 
is running on to examine each AppleTalk packet it is about to write to 
the network.   If it meets operator-defined criteria, the packet can be 
altered and controlled in a variety of ways.

Features: oPackets can have their size changed, data altered, protocol 
parameters changed, or their transmission delayed or repeated.  
oThe user-defined criteria currently includes matching such traits for 
the AppleTalk Protocols: ASP, ATP, ADSP, DDP, LLAP, NBP, and PAP.
oA distribution scenario can be set up to introduce random and selective 
snarfing of packets.
oFiles can be saved to hold the user-defined critieria and actions that 
users create.
oThe Snarfer can run on Internet Routers and handle multiple ports.

Requires: Any Macintosh (starting from Mac Plus) running system 6.0 or 
later.

Issues: The Snarfer is currently being considered for a patent filed by 
Apple.  So far, it is a low priority patent.
