How to check eth0: speed

fparodi · 05-12-2007, 05:42 PM

Hi,
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?
Tx

You could try as root user ( su - )
/sbin/mii-tool eth0

Thanks for the hint.
Looking at the man page for mii-tool I found such command has been replaced by /sbin/ethtool.

I beleive ethtool replaced mii-tool as it supports Gigabit interfaces (mii-tool doesn't).

Thanks
