ethtool configuration

[monu_1]

Hi Guru,

which one of following is true and why?

1) ethtool can be used to configure the parameters.
2) ethtool can only be used to read the parameters.


Thanks,

like your way, both are correct. ethtool is used for Display or change ethernet card settings.

#man ethtool

Shalom,

A quick look at the man page will tell you both and many more things are possible.

thanks for suggestion!

#ifconfig net0
Link encap:Ethernet HWaddr 00:00:02:01:02:09
inet6 addr: fe80::200:2ff:fe01:209/64 Scope:Link

#ethtool net0
net0 does not appear a to be an ethernet device

Why it's not eth device? how can i change net0 duplex and speed setting?

Thx,
