Front end for OS X's built-in network monitoring tools.

PacketStream provides a user-friendly GUI for tcpdump, a command-line network monitoring tool included in Mac OS X. By pointing and clicking, you can monitor data as it streams over your network--especially useful for checking web traffic, network bottlenecks, or even suspicious network activity. PacketStream offers a simple way to configure and use the Mac's network monitoring tools, far easier than typing in cryptic commands in Terminal.
