Changing MAC address

[amitatharkar]

Hi all,
Is there any way in linux to change the MAC address.
I need this because i have cable net at home and the ethernet card is provided by ISP. I want to change that one. And the connection is based on the MAC address. I tried with new card but it is not allowing me to login.

Do like this:

ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx

It only works if the driver supports it though.

Cheers

I thought MAC addresses were set in the hardware of the ethernet card? You sure you can do this at the OS level?

You're not changing the MAC address on the card. You're changing the MAC address the IP stack uses in communications.

Wonboodoo is right. That is not possible to change MAC address.MAC address provided by hardware(NIC).Each hardware(NIC) has unique MAC address.Let me know if you can change it.Good Luck....
