How do you tell if your network card is running at 10 or 100 Meg?
THanks,

Actually, I don't think mii-tool gives that info (at least, it didn't give the current speed when I tried it). Plus, it's deprecated. ethtool on the otherhand does give that info.

mii-tool does give the info requested as seen below:
[root@insanity ~]# mii-tool eth0: negotiated 100baseTx-FD, link ok
however ethtool gives significantly more. Apparently I'm a bit behind the times in my networking scripts. I was unaware that mii-tool was considered deprecated. Good to know. -- Jim Perrin System Architect - UIT Ft Gordon & US Army Signal Center

Weird. My copy didn't give that:
[root@mis-develop plates]# mii-tool eth0: negotiated, link ok eth1: no link

mii-tool does not work for 1000 networks either.

mii-tool doesnt give you gigabit speeds it will work for 10/100 not 10/100/1000
you can use dmesg and grep to see what was negotiated
dmesg |grep eth eth0: SiS 900 PCI Fast Ethernet at 0xc800, IRQ 217, 00:13:d4:13:00:7b. eth0: Media Link On 100mbps full-duplex eth0: no IPv6 routers present

Correct, because the Media Independent Interface (MII) PHY (physical chip) specification pre-dates GbE. It was designed for FE.
Ethtool works with the newer GigaBit Interface Converter (GBIC) PHY specification.

Do a 'man' on ethtool. Should tell you what you're looking for. -Alan
