This is easy if as long as one of the Fedora servers is also the DHCP
server. It may not be possible if your DHCP server is a consumer grade
appliance (e.g. a wireless router box) as these devices cannot typically
be configured to send the notifications as far as I know. You need to
configure the DHCP daemon to do dynamic updates - add the following to
the top of /etc/dhcpd.conf:
ddns-update-style interim;
ddns-updates on;
Assuming the DHCP server is on the same machine as named, you need to
add "allow-update { localhost; };" to the appropriate zone sections
in /etc/named.conf. For example:
zone "1.168.192.in-addr.arpa" {
type master;
file "1.168.192.in-addr.arpa.zone";
allow-update { localhost; };
};
zone "mydomain.com" {
type master;
file "mydomain.com.zone";
allow-update { localhost; };
};
