ifstat - A little like a vmstat for network interfaces. This is pretty handy for a quick look at network saturation without have to break out some massive GUIfied tool with a hideous interface.

asbestos:\~# ifstat -b -i eth0,eth1,eth2,eth3
       eth0                eth1                eth2                eth3

There is a debian package. And note that “-b” option to report in bits/second instead of bytes. What kind of person measures network use in bytes per second?

And in the same vein: iostat is hiding over in the systat package on debian. Use it too.
