Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

On a fedora server i have access using a ssh connection. As a regular user, how can I see what traffic is involved into the server?

I don't have root rights, and I'll like to learn from the default tools already installed. I assume that all I can use is a cli type tool.

Until now, I was playing with top (which is so cool comparing with ms windows tools), but I'll like to see/learn stuff about traffic too.

There are many tools available to check the network traffic coming in/out of your server.

If you want to see bandwidth related information, you can use a tool like ntop or nload.

If you want to see detailed packets information (sniffing), you can use a tool like tcpump or tshark.

However, most of these tools (if not all) require root privileges. At least, you need to have them installed.

on any of them I get a 'command not found' –  dole doug Dec 12 '11 at 14:03
    
It seems that they are not installed. You can try them on another machine with root privileges :) –  Khaled Dec 12 '11 at 14:05

This will be nearly impossible without root rights. But if you ever manage to get it to work, IPTraf may be a useful tool for you.
