I have a machine runnign 12-STABLE, which gets its upstream IP address
from my ISP using DHCP over a cable modem. What I just tried to do was
to set the MAC address on that interface at boot time, but if I do that
then it no longer acquires a DHCP address from the upstream.
Is there something going on here I dont understand ?
The interfaces are 'bge' and I have a file called /etc/start_if.bge0
whcih contains:
/sbin/ifconfig $1 ether d0:bf:9c:46:a3:7c
and this works (have tried it on bge1 and another machine) in changing
the MAC address. But if i do that on the DHCP interface then it doesnt
get an IP address.
Any hints ?
-pete.
PS: reason am doing this is my ISP will (in future) be able to give me
a static IP address basd on the MAC address. Which is lovely, but I have
a spare server I use when this one goes down, so was hoping to have the
same MAC address if I boot the same drive, to avoid any issues caused by
the MAc address chnaging if I chnage the hardware. But it doesnt work. :)
