As for the "assume" thing, speak for yourself. Your implication that there should be no defaults is quite asinine. If it doesn't work with no netmask specified, then its broken. Its not unreasonable to assume that if no netmask is provided, then a host mask (for an alias) is intended. In the absence of a netmask, the only "assumption" thats reasonable is a host mask. There are lots of "assumptions" made by ifconfig. It "assumes" that you only want the interface to have one address (as if you submit an address to an interface that already has one it explicitly deletes the other). Its not unreasonable to assume that, nor would it be unreasonable to assume that the intention was to add an alias. It would certainly be safer. And I "understand" it a lot better than you do. In today's world, "assuming" the natural mask (which is what ifconfig has done since the beginning of time) is wrong most of the time. Just because someone back in the 1970s decided to do it that way doesn't make it correct. One of the basic properties of a default setting is that it should work. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-que --ANTIGEN-7051-1937-4701-3342-29869-31729--
