I configured Bind 9.18.12 as slave DDNS with dynamic updates from DHCP (ISC DHCP 4.4) running on the same server (Ubuntu 22.04 server)When I run "named-checkconf named.conf", I get the following error "named.conf:2018: option 'allow-update' is not allowed in 'slave' zone 'zonename.com'" Following is the named.conf file (part) zone "zonename.com" { type slave; file "com/zonename/sec.zonename.com"; masters { IP address; }; allow-update { key rndc-key; }; allow-transfer { IP address; }; }; I am clueless what is going wrong. Any help is greatly appreciated
your nameserver does not update secondary(slave) zones, therefore allow-update does not make sense.
you should remove it or replace with allow-update-forwarding so all received updates are forwarded to primary(master) server.
