The above message is usually indicative that _other_ machines on your net are misconfigured. That is, someone is looking for that IP address (one which belongs in Brazil by the way) on your LAN. > Sep 17 01:13:01 blacksheep /kernel: arp: 192.168.0.254 moved from 00:a0:cc:5d:c3:70 to 00:a0:cc:5d:cb:70 on ed0 > Sep 17 01:13:11 blacksheep /kernel: arp: 192.168.0.254 moved from 00:a0:cc:5d:cb:70 to 00:a0:cc:5d:c3:70 on ed0 This is telling you that the hardware address associated with that IP address has changed. This usually means that a different machine is claiming the IP address. Again, this is telling you about events on the network and does not mean there is any trouble with the machine making these messages. > The 192.168.0.254 address is my gateway. What kind of gateway is this? The addresses belong to a piece of hardware from "Lite-On Communications." > I don't know where the 200.168.254 > address is coming from.
