See live network throughput per process in a Linux shell

Question

I am looking for a free program that can display the live network throughput per process in the Linux shell. As far as I know:

• ifconfig only lists interfaces and doesn't display the live network throughput:

  eth0   Link encap:Ethernet  HWaddr 00:0F:20:CF:8B:42
         inet addr:217.149.127.10  Bcast:217.149.127.63  Mask:255.255.255.192
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:2472694671 errors:1 dropped:0 overruns:0 frame:0
         TX packets:44641779 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:1000
         RX bytes:1761467179 (1679.7 Mb)  TX bytes:2870928587 (2737.9 Mb)
         Interrupt:28
  

• slurm only lists interfaces:

  

• bmon only lists interfaces:

  

• tcptrack shows every connection:

  

• iftop does not display throughput per process:

  

Answer 1

You can use NetHogs:

• free

• install with sudo apt-get install -y nethogs

• runs in the terminal

• display the live network throughput per PID:

  

Note that for NFS/AFS traffic you will see ? as PID:
