How to check eth0: speed
I have a 10/100/1000 Ethernet NIC on my Fedora 6 PC.
The server is connected to a Gigabit capable switch, but I can see via System Monitor I can get only ~2.1MiB/sec of incoming data.
I would like to check if my Eth0: is actually working as 10Mb, 100Mb or 1Gb port, but I don't know how.
Can someone help me on this please?
