how can I find connection info of an application which is currently downloading at top speed?

Question

I noticed from the InfoPanel screenlet that my computer downloading something at high speed. I was not downloading anything and I already ran apt-get upgrade so there was no apparent reason for my comp to download something. I tried to run some well known network checking commands but they didn't help much since they don't list connections by speed rate:

netstat -A inet -p | grep '^tcp' | grep '/' | sed 's_.*/__' | sort | uniq

ss -tp | grep -v Recv-Q | sed -e 's/.*users:(("//' -e 's/".*$//' | sort | uniq

Is there any tool you know that lists connections by speed rate like command top does ?

nethogs was the best one --- but it is not working in my system now. Hmm.... — Rmano, Mar 12 '16 at 19:05

nethogs seems to be what I want. It's pity that we have no alternatives. — kenn, Mar 12 '16 at 21:13

I think that the best tool is nethogs.

Unfortunately, the version available in Ubuntu 14.04 is broken, so you have to compile it yourself: See Nethogs → creating socket failed while establishing local IP - are you root?.

After that, just run:

sudo nethogs wlan0

where wlan0 is the name of the interface you want to monitor.

Use q to exit.
