iftop: display bandwidth usage on an interface
How to install?
- Download and install the Universal Binary from here
- Or if you already have MacPort installed
sudo port install iftop
How to use it?
- run “ifconfig -l” or “/Applications/Utilities/Network\ Utility.app” to get your network interface id.
- In my case is ‘en1′, so I just type into Terminal:
sudo iftop -i en1
