Tested on 8.4-STABLE: ifconfig em0 10.2.3.4/24 ifconfig em0 down or, in rc.conf ifconfig_em1="inet 10.2.3.4/24" ifconfig_em1_alias0="down" I find this use of alias clumsy, and it *should not* be necessary. In both cases there is probably a small window where the interface is up and answering for the specified IP address. (I also tried ifconfig em0 10.2.3.4/24 down which didn't work - the interface is left in the UP state.) Steinar Haug, Nethelp consulting, sthaug@nethelp.no
