Nethogs voipi olla kaipaamasi ohjelma. Repoista löytyy.
"DESCRIPTION
NetHogs is a small ’net top’ tool. Instead of breaking the traffic down per protocol or per subnet, like most such
tools do, it groups bandwidth by process - and does not rely on a special kernel module to be loaded. So if there’s
suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this, and if it’s
some kind of spinning process, kill it."
