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.

Features:

• Simple to use: Set a couple of user preferences, click a button, and go.
• Save network data to a file or print for later analysis.
• Monitor traffic on specific network ports.
• Thorough user documentation via the "Help" menu.
• AppleScript and Services support.
• Keychain integration.
• No need to build mulitple network monitoring libraries and non-Mac-native GUI's from source code.
• Actively maintained and improved.

Requirements:
OS X 10.9+
64-bit Intel
