Is there a htop/top on Linux where I get to sort processes by network usage?
This question is related to
linux
networking
top-command
htop
The answer is
Also iftop:
display bandwidth usage on an interface
iftop does for network usage what top(1) does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts. Handy for answering the question "why is our ADSL link so slow?"...
iptraf is my favorite. It has a nice ncurses interface, and options for filtering, etc.
Another option you could try is iptstate.

NetHogs is probably what you're looking for:
a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process.
NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to identify programs that have gone wild and are suddenly taking up your bandwidth.
Since NetHogs heavily relies on /proc, most features are only available on Linux. NetHogs can be built on Mac OS X and FreeBSD, but it will only show connections, not processes...

Check bmon. It's cli, simple and has charts.
Not exactly what question asked - it doesn't split by processes, only by network interfaces.
