root@dlp:~# vi /etc/bind/named.conf.options options { directory "/etc/bind"; // If there is a firewall between you and nameservers you want // to talk to, you may need to fix the firewall to allow multiple // ports to talk. See http://www.kb.cert.org/vuls/id/800113 // If your ISP provided one or more IP addresses for stable // nameservers, you probably want to use them as forwarders. // Uncomment the following block, and insert the addresses replacing // the all-0's placeholder. // forwarders { // 0.0.0.0; // }; # add a range you allow to transfer zones allow-transfer { localhost; 10.0.0.0/24; 172.16.0.80/29; };auth-nxdomain no; # conform to RFC1035 # listen-on-v6 { any; }; }; root@dlp:~# rndc reload server reload successful |
