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.
lsof but the output looks so NOT friendly. Maybe there are some tricks to use it? Or there are better alternatives?
