Dear All I have a CentOS 6.3 machine. I am trying to setup DNS BIND setup in that machine. It is having a static global IP. I have done lot of reading , google search and tried all possible option, but still not able to resolve the issue. My named.conf looks as below. * * * // named.conf // // Provided by Red Hat bind package to configure the ISC BIND named(8) DNS // server as a caching only nameserver (as a localhost DNS resolver only). // // See /usr/share/doc/bind*/sample/ for example named configuration files. // options { listen-on port 53 { 127.0.0.1; 10.0.0.1; }; listen-on-v6 port 53 { ::1; }; directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; query-source address * port 53; statistics-file "/var/named/data/named_stats.txt"; memstatistics-file "/var/named/data/named_mem_stats.txt"; allow-query { localhost; 10.0.0.1/24; 10.0.0.254/24; }; recursion yes; dnssec-enable yes; dnssec-validation yes; dnssec-lookaside auto; /* Path to ISC DLV key */ bindkeys-file "/etc/named.iscdlv.key"; managed-keys-directory "/var/named/dynamic"; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; zone "." IN { type hint; file "named.ca"; };zone "netcloudjobs.com" { type master; file "netcloudjobs.com.fwd"; allow-update { none; }; }; zone "189.201.173.in-addr.arpa" { type master; file "netcloudjobs.com.rev"; allow-update { none; }; }; include "/etc/named.rfc1912.zones"; include "/etc/named.root.key"; * Next my forward zone file looks as below * $TTL 86400 @ IN SOA ns1.netcloudjobs.com. root.netcloudjobs.com. ( 2021071001 ;Serial 3600 ;Refresh 1800 ;Retry 604800 ;Expire 86400 ;Minimum TTL ) @ IN NS ns1.netcloudjobs.com. @ IN NS ns2.netcloudjobs.com. ns1 IN A 173.201.189.43 ns2 IN A 173.201.189.43 * And my reverse zone file looks as *$TTL 86400 @ IN SOA ns1.netcloudjobs.com. root.netcloudjobs.com. ( 2021071001 ;Serial 3600 ;Refresh 1800 ;Retry 604800 ;Expire 86400 ;Minimum TTL ) @ IN NS ns1.netcloudjobs.com. @ IN NS ns2.netcloudjobs.com. ns1 IN A 173.201.189.43 ns2 IN A 173.201.189.43 43 IN PTR ns1.netcloudjobs.com. 44 IN PTR ns2.netcloudjobs.com. * I hope I am doing something wrong with configuration. I have done this since more than 60 hours. Still I am not able to resolve ns1.netcloudjobs.com. Can somebody help here. Best Regards Austin
