Code by Kevin has released PacketStream 2.0, a network monitoring program for Mac OS X. 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, users can monitor data as it streams over a network — especially useful for checking Web traffic, network bottlenecks, or even suspicious network activity. Version 2.0 features: new icons for greater ease-of-use; search the data display for specific terms; and configure scanner to monitor specific specific network ports. PacketStream requires Mac OS X 10.4 or later, and is priced at US$20. A 30-day demo is available.
