Here is the secondary for when the machine is booted in FreeBSD: -------------------------------------------------------------------------- ; zone 'lambert.org' last serial 199609260 ; from 161.28.224.20 at Wed Apr 16 02:26:39 1997 $ORIGIN org. lambert IN SOA park.uvsc.edu. terry.lambert.org. ( 199704160 21600 3600 2419200 86400 ) IN NS park.uvsc.edu. ; Ignoring info about park.uvsc.edu, not in zone lambert.org. ; $ORIGIN uvsc.edu. ; park 566122 IN A 161.28.224.20 $ORIGIN org. lambert IN NS sting.artisoft.com. IN MX 10 phaeton.artisoft.com. IN MX 20 coyote.artisoft.com. -------------------------------------------------------------------------- sting.artisoft.com is an alias for phaton.artisoft.com, and is delegated to an IP alias which varias based on what OS the physical machine is booted under, in order o make the MX records not refer to itself unless the machine is booted FreeBSD. Basically, the "phaeton" MX blinks on and off in DNS for whatever IP "sting" is an alias for at the moment. Anyway, that's enough information about this. The fact is, it works, despite BIND's whining, when the primary DNS is down and phaeton is subtracted out by virtue of being DNS software running on an OS other than FreeBSD. This is a typical configuration for when the physical hardware phaeton resides on is booted to another OS (NetBSD, OpenBSD, Windows95, Windows NT, OS/2, Linux).
