An alias would be nice. A standby system must be reachable before it will be active and will need another MAC to be. But I don't see any sence in having more than one MAC on one IP-Address. So talking on IP it should be an optional argument to the ip-alias. -- B.Walter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
