Code by Kevin has released PacketStream 4.0 (http://www.codebykevin.com/packetstream.html), an update to its Macintosh network-monitoring program. The upgrade sports an improved appearance with a native Cocoa toolbar, enhanced documentation and some bug fixes.
 
PacketStream provides point-and-click activation of the Mac’s built-in network monitoring program, which is usually available only from the command line. By clicking a few buttons, you can monitor data as it streams over your network. All network data is displayed in the application itself, and you can save the data to a file for further analysis later.
 
PacketStream is shareware. Licenses cost US$24.99 and a 30-day demo is available. The program requires Mac OS X 10.6 to run.
