Of-course there is no sense in typing things like that, by ifconfig.core is not the right reaction of the program. This is not somethig new (in 4.7) it surely happens in 4.6-STABLE and probably previous versions. I just did not had the time to submit it earlier, also I wasn't able to mail to @freebsd.org, because of the "450 Client host rejected: cannot find your hostname" Postfix err. >How-To-Repeat: As I suppose everyone has the loopback interface so the following should do: ifconfig lo0 ether 0 -alias >Fix: cd /usr/src/sbin/ifconfig && hack >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
