 NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to identify programs that have gone wild and are suddenly taking up your bandwidth.
 
 Since NetHogs heavily relies on `/proc`, most features are only available on Linux.
-NetHogs can be built on Mac OS X, but it will only show connections, not processes.
+NetHogs can be built on Mac OS X and FreeBSD, but it will only show connections, not processes.
