Changing MAC address of a NIC


I have a need to software change the MAC address of a NIC in a Sparc Ultra 10 - I believe there is a command that allows to do this at boot up?

Is it a missing (to me) part of ifconfig ?

If so, what is the syntax?

All replies gratefully received !

To my knowledge you can't change a mac address of
a network card.

the only way to change the mac address is to replace the network card.

ifconfig command is use to change the ip address or display ip address not mac address

arp -a will display the mac address of your network card

there is no way to spoof the mac of a network card via software.

if you have time and some eprom buring euiq. around then you can change the mac addy of a card.

please note. these boards are not for hacking related questions.

The man page for ifconfig on Sun says:
To change the Ethernet address for interface le0, use the following command:
example% ifconfig le0 ether aa:1:2:3:4:5
