I've been running 3.0-alpha-19990424 successfully for about 24 hours
now, but I noticed a bunch of irritating log messages like this:
Apr 27 16:04:02 arachne dhcpd: DHCPREQUEST for 192.168.1.3 from 00:60:97:a4:35:91 via
eth0: ignored.
What bothers me is that 192.168.1.3 is not in any of the subnets I
have declared, witness my attached dhcpd.conf file. I would therefore
have expected dhcpd to NAK it instead of ignoring it. Btw, old leases
from a previously used address pool which I declared "deny all clients"
are NAKed alright.
I noticed a new dhcpd.conf option "authoritative" specifying whether
the server should NAK requests for addresses it knows nothing about,
but if I read the man page correctly it is on by default.
