[1] | Install BIND. |
root@dlp:~# apt -y install bind9 bind9utils
|
[2] | On this example, Configure BIND for External Network. The example follows is for the case that External network is [172.16.0.80/29], Domain name is [srv.world], Replace them to your own environment. ( Actually, [172.16.0.80/29] is for private IP addresses, though. ) |
root@dlp:~#
vi /etc/bind/named.conf include "/etc/bind/named.conf.options"; include "/etc/bind/named.conf.local"; include "/etc/bind/named.conf.default-zones"; # add include "/etc/bind/named.conf.external-zones";
root@dlp:~#
vi /etc/bind/named.conf.options options { directory "/var/cache/bind"; ..... ..... # add : receive queries from all hosts allow-query { any; }; # network range you allow to transfer zone files to clients # add secondary DNS servers if it exist allow-transfer { localhost; }; # add : not allow recursion recursion no; //======================================================================= // If BIND logs error messages about the root key being expired, // you will need to update your keys. See https://www.isc.org/bind-keys //======================================================================= dnssec-validation auto; # if not listen IPV6, change [any] to [none] listen-on-v6 { any; }; };
root@dlp:~#
vi /etc/bind/named.conf.external-zones # create new # add zones for your network and domain name zone "srv.world" IN { type master; file "/etc/bind/srv.world.wan"; allow-update { none; }; }; zone "80.0.16.172.in-addr.arpa" IN { type master; file "/etc/bind/80.0.16.172.db"; allow-update { none; }; }; # if you don't use IPv6 and also suppress logs for IPv6 related, possible to change # set BIND to use only IPv4 root@dlp:~# vi /etc/default/named # add OPTIONS="-u bind -4 "
# For how to write the section [*.*.*.*.in-addr.arpa], write your network address reversely like follows # case of 172.16.0.80/29 # network address ⇒ 172.16.0.80 # network range ⇒ 172.16.0.80 - 172.16.0.87 # how to write ⇒ 80.0.16.172.in-addr.arpa |
