[Gllug] Fedora 16 MAC Address

Uh, the locally administered bit is not the top bit. The locally
administered bit is the next-from-bottom bit of the top octet. See, e.g.
include/linux/etherdevice.h:random_ether_addr() in a recent Linux kernel
tree.

And (unless I've typoed) not all these addresses have that bit set.

ifconfig is by now very obsolete and frequently misleading (though not
in this case). You want 'ip link set address'.

ip link set address ascii-mac-address dev (device)
