I'm using a PC-BSD workstation, and I would like to know if there is a way to monitor which app / process is using the network.
I use a Mac OS X (Mavericks) laptop, and the "Network" tab in the "Activity Monitor" allows to see which process is sending / receiving data to / from the network. But I don't see (or haven't found) anything like that in FreeBSD. Since Mac OS X is similar to FreeBSD under the hood, is there any graphical app (similar to System Monitor) or command-line utility (similar to
top) to monitor network activity for each process?
