Take the 2-minute tour ×  I am noticing some unusual network
data transfer activity. Is there any software that can show the
amount of network data transfer is process is doing.

Answers  up vote 9 down vote accepted  You could use nethogs to
see the speed of transfer for each process.  sudo apt-get
install nethogs  Run it in terminal by running sudo nethogs but
if you have more than one network device, you may need to
specify it like so:  sudo nethogs eth0 sudo nethogs eth1   sudo
nethogs wlan0   sudo nethogs wlan1    A picture of nethogs
working with a chrome opening a webpage:  Nethogs in Action  You
also have bmon which shows you ethernet devide usage.  sudo apt-
get install bmon  and just run it like sudo bmon it will show
you all network devices are their usage BMON in Action
