How could I change my mac address during installation?

For some reasons I have to change my address to touch internet, but I don't know how to do it right after installation.

I tried in  file rc.conf

eth0='............. hw ether xxxxxxxxxxxx'

but failed

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

eth1="eth1 hw ether 00:00:00:00:00:FF dhcp"
INTERFACES=(lo eth1)
or do i do something else?

For dhcp, you need to do something a little more custom-made - the syntax above won't work. You could put all the required commands in /etc/rc.local, or you could use netcfg with the mac-changing command as a PRE_UP.

netcfg details here.

Re: How could I change my mac address during installation?

could you elaborate on the PRE_UP, the wiki didn't say much about it, where do i put it(in the netcfg network profile?) and how does it work?

and in the wiki for
NETWORKS=("auto-wireless <interface>" ipw0 ethernet)
what the "auto-wireless <interface>" does is that it scans for available networks in the current vicinity am i correct? does this scan for all networks or only certain networks specified the the profile files?

and for In rc.conf set NETWORKS=() to menu. to get a menu at boot do i do something like this:
NETWORKS=(menu profile1 profile2)?

Have a look in /etc/network.d/examples - PRE_UP is explained in one of them.
