Rubbernet 1.1

Rubbernet is a network monitoring tool for the Mac. It can tap into your Mac's network interface and actively monitor everything that goes in or out of your computer. It can detect all the applications that are connected to the Internet and even tell you about where they are connecting to and what they are sending.

Rubbernet shows a list of the running applications that are connected to the Internet both on the main window and on a pane to the left, where you can access different data views. For example, there are two views under the "Overview" category, namely Summary and Connections. Summary simply shows all the applications that are getting data from the Internet or your local network and it displays the user account that those apps are operating from, the name of the app, the port, the status, the total downloaded and uploaded data and the current speed. At the bottom are two graphs that show the download and upload speeds.

Under "Activity" you can click on the active apps and get more detailed reports, along with remote hosts, ports, speed, and last activity times.

All in all, this is a nice app that can be used to monitor which apps are going on the Internet and see what they are doing. You can also use it as a traffic meter, thanks to its graphs and real-time data on downloads and uploads.
