Determening duplex setting on NIC

Hi All,

We have a couple of Redhat 7.x servers

I need to document the NIC duplex settings and speed.

On kernel 2.4.18-3, I use mii-tool and get the info I want.

However, some of the servers still run kernel 2.2.19-x and mii-tool doesn't seem to be installed.

Short from downloading and installing the rpm, what command can I use to determine the duplex / speed of the NIC?

Regards,
Jo

Is there anything useful in the dmesg output?

Chances are that kernels that old are running hardware that does not support MII tranceiver status, but assuming
that the hardware DOES support it, simply download mii-diag from Donald Becker

wget ftp://ftp.scyld.com/pub/diag/mii-diag.c
make mii-diag
mv mii-diag /usr/local/sbin

PS: He's the guy who probably wrote the device driver for your card, so you should be able to trust the code here

Does ethtool exist on that version?

It's been so long I really can't remember.

It may have been.  

A *quick* check for ethtool seems to indicate it wasn't in RH6.1, but I don't have that distro handy.

But since mii-diag is such a small program (one file), its probably easier and faster to grab it rather than track down
any rpm's for his systems.
