21.3. Adding a Slave Zone
To add a slave zone (also known as a secondary master), click the
New button and select . Enter the domain name for the slave zone in the
Domain name text area.
A new window will appear, as shown in Figure 21-4,
with the following options:
Name — The domain name that was entered
in the previous window.
Masters List — The nameservers from which
the slave zone retrieves its data. Each value must be a valid IP
address. You can only enter numbers and periods (.) in the text area.
File Name — File name of the DNS database
file in /var/named.
After configuring the slave zone, click OK to
return to the main window as shown in Figure 21-1. Click Save to write the
/etc/named.conf configuration file and have the
daemon reload the configuration files.
The configuration creates an entry similar to the following in
/etc/named.conf:
zone "slave.example.com" {
type slave;
file "slave.example.com.zone";
masters {
1.2.3.4;
};
}; |
The configuration file
/var/named/slave.example.com.zone
is created by the named service
when it downloads the zone data from
the master server(s).
