What can I use to monitor which IP address w/name resolution is connected to each PID?

Question

This would be for under Linux particularly.

Is there a tool out there, or a script that I could use to monitor IP connections--with name resolution--and, see which process they're connected to?

Right now I'm using this:

watch -d netstat -peeW --numeric-hosts --inet

But that doesn't give me host resolution. I was thinking of writing up a script with sed or something, but that seemed like more work than it needed to be.

Answer 1

Getting rid of --numeric-hosts will tell netstat to do address lookups.

Answer 2

I would use the following

sudo lsof -i -n -a

(You could also use fuser)
