I have searched the internet for this answer, but to have not been able to find one. What is the proper syntax for "allow-transfer { lan; }" to do updates using my RNDC key? Per my example below, it does allow it but when I start named, I get an error that allowing update via IP address is insecure. Thanks for your help. // Define address range for the local domain. acl lan { 192.168.100/24; 127.0.0.0/24; }; options { directory "/var/named"; /* * If there is a firewall between you and nameservers you want * to talk to, you might need to uncomment the query-source * directive below. Previous versions of BIND always asked * questions using port 53, but BIND 8.1 uses an unprivileged * port by default. */ // query-source address * port 53; // Only allow queries and listen from the local domain. allow-query { lan; }; allow-recursion { lan; }; allow-transfer { lan; }; listen-on { 127.0.0.1; 192.168.100.1; }; }; // Top Level domain name servers. zone "." IN { type hint; file "named.ca"; }; // Localhost Zones zone "localhost" IN { type master; file "localhost.zone"; allow-update { lan; }; }; // Provide a reverse lookup for the loopback address 127.0.0.1 zone "0.0.127.in-addr.arpa" IN { type master; file "named.local"; allow-update { lan; }; }; // Home network zone. zone "mylan.lan" IN { type master; file "named.mylan"; notify no; allow-update { lan; }; }; __________________________________________________ Do You Yahoo!?
