Hi, I've copied my hard drive to another hard drive using dd. The machines are almost the same, but the first one was from another person. After the copy, I've noticed that the machine was working in the network, wich seems impossible because I have a DHCP server witch atribute IP address per MAC address. After that I've noticed that the file ifcfg-eth0 on my system had the followwing line: HWADDR=xx:xx:xx:xx:xx:xx And the MAC in there, was the MAC of the NIC of the first machine, not the one I'm running now. My question is, it's not a security flaw let someone change the MAC that way??? Thanks!
