Sometimes I can see heavy usage of network in my Gnome System Monitor. I wonder what process is downloading/uploading data. Is there any tool which can show me:
- what processes are using the Internet
- a dynamic real-time view of the download/upload speed of these processes
- the details of the connections (e.g. the remote IP, the port number, etc.)
My system is Ubuntu 10.10.
I tried lsof but the output looks so NOT friendly. Maybe there are some tricks to use it? Or there are better alternatives?
