How to modify MAC address?
Hi,if I want to modify my MAC address at boot time by default,how can I do?
I get my IP address by DHCP,and the IP address is banded to the MAC address.
Thank you!

Re: How to modify MAC address?
Add this to one of the startup scripts, it only has to be executed before you start networking. (I'm not sure about the execution order, I'm sorry.)
ifconfig eth0 hw ether xx:xx:xx:xx:xx:xxOffline

Give what you have. To someone, it may be better than you dare to think.

I ever add this to /etc/rc.local,it works,but I still can't get IP address.
If I run "/etc/rc.d/network restart",I can get my IP address,as a result of this,my OS get slowly,why?

isn't slowly. to change your mac adress you need to changed it before eth0 is going up(i don't know why you don't see an error SIOCSIFHWADDR: Device or resource busy ). if you prefer that solution you need to add:
ifconfig eth0 down
ifconfig eth0 hw ether bla:bla:....
ifconfig eth0 up
but i prefer the first solution that i showed you.

Re: How to modify MAC address?
at boot rc.local runs at the end of the boot process, thus rc.d/network is run before. that's why you have to rerun rc.d/network.

To know recursion, you must first know recursion.
