problem updating dynamic dns from isc dhcpd

[Bill Shirley]

named.conf:
         zone "4.168.192.in-addr.arpa"   {


dhcpd.conf
ddns-rev-domainname "in-addr.arpa";
zone 4.168.192.in-addr.arpa.    { primary 127.0.0.1;    key DHCP_UPDATER; }

HTH,
Bill

But since you are using signed updates, you must specify zones in dhcpd.conf - the syntax is *almost*, but not quite, identical to that in named.conf.
