OPTIONS<\/span>=<\/span>\"-4 -u bind\"<\/span><\/code><\/strong><\/pre>\nSave and exit.<\/span><\/p>\n<\/div>\n<\/div>\nNow that BIND is installed, let\u2019s configure the primary DNS server.<\/p>\n
<\/span>Creating Zones entries<\/span><\/h3>\nFirstly we will create a forward zone entry in \/etc\/named.conf for our domain webhostingnoida.com. Add the following lines in named.conf<\/p>\n
zone \"webhostingnoida.com\" IN {\r\ntype master;\r\nfile \"fwd.webhostingnoida.com.db\";\r\nallow-update { none; };\r\n};<\/strong><\/pre>\nHere, \u2018webhostingnoida.com\u2019<\/strong> is the Domain name,<\/p>\n\u2018master\u2019<\/strong> is the Primary DNS,<\/p>\nfwd.webhostingnoida.com.db<\/strong> is the Forward lookup file,<\/p>\n\u2018allow-update\u2019<\/strong> will be none, its the primary DNS.<\/p>\nSimilarly, we will now create an entry for reverse zone as well in\u201dnamed.conf\u201d<\/p>\n
zone \"1.168.192.in-addr.arpa\" IN {\r\ntype master;\r\nfile \"1.168.192.db\";\r\nallow-update { none; };\r\n};<\/strong><\/pre>\nHere,<\/p>\n
1.168.192.in-addr.arpa<\/strong>\u00a0 is Reverse lookup name,<\/p>\nmaster<\/strong>\u00a0is for Primary DNS,<\/p>\n1.168.192.db<\/strong>\u00a0is the\u00a0reverse lookup file,<\/p>\nallow-update<\/strong> \u2013 will be set to none, since this is the primary DNS.<\/p>\nOur configuration for \u201cnamed.conf\u201d is complete & next we will create zone files for our BIND server.<\/p>\n
<\/span>Creating zone files<\/b><\/strong><\/span><\/h3>\nWe will first create our forward zone file i.e \u201cfwd.webhostingnoida.com.db<\/strong>\u201d in \u201c\/var\/named<\/strong>\u201d folder and then will make the following entries in it<\/p>\n$TTL 86400\r\n@ IN SOA primary.webhostingnoida.com. root.webhostingnoida.com. (\r\n2014112511 ;Serial\r\n3600 ;Refresh\r\n1800 ;Retry\r\n604800 ;Expire\r\n86400 ;Minimum TTL\r\n)\r\n;Name Server Information\r\n@ IN NS primary.webhostingnoida.com.\r\n;IP address of Name Server\r\nprimary IN A 192.168.1.100\r\n;Mail exchanger\r\nwebhostingnoida.com. IN MX 10 mail.webhostingnoida.com.\r\n;A - Record HostName To Ip Address\r\nwww IN A 192.168.1.105\r\nmail IN A 192.168.1.120\r\n;CNAME record\r\nftp IN CNAME www.webhostingnoida.com.<\/strong><\/pre>\nSimilarly, we will create reverse zone file named \u201c1.168.192.db\u201d<\/strong><\/em> in \u201c\/var\/named<\/strong><\/em>\u201d folder with the following content<\/p>\nvi \/var\/named\/1.168.192.db<\/strong><\/pre>\n\n
$TTL 86400\r\n@ IN SOA dns.ltechlab.com. root.ltechlab.com. (\r\n2014112511 ;Serial\r\n3600 ;Refresh\r\n1800 ;Retry\r\n604800 ;Expire\r\n86400 ;Minimum TTL\r\n)\r\n;Name Server Information\r\n@ IN NS dns.ltechlab.com.\r\n;Reverse lookup for Name Server\r\n8 IN PTR dns.ltechlab.com.\r\n;PTR Record IP address to HostName\r\n105 IN PTR www.ltechlab.com.\r\n120 IN PTR mail.ltechlab.com.<\/strong><\/pre>\n<\/div>\n <\/p>\n
After creating these zone files, we will restart our BIND server<\/p>\n
service named restart or\r\nsystemctl restart named.service<\/strong><\/pre>\nNow, we will verify our zone files.<\/p>\n
<\/span>Test the DNS server<\/span><\/h3>\nNow we have configured the DNS server for our domain. We will test our DNS server by pinging mail.webhostingnoida.com from web.webhostingnoida.com.<\/p>\n
If the ping is success, then we have configured the DNS successfully.<\/p>\n
You can also use nslookup and dig to test DNS servers.<\/p>\n
On web.webhostingnoida.com server, add the following to \/etc\/resolv.conf<\/p>\n
nameserver 10.42.0.83<\/strong><\/pre>\nNow ping, mail.webhostingnoida.com, which should resolve the address appropriately from the DNS server that we just configured.<\/p>\n
$ ping mail.thegeekstuff.net\r\n\r\nPING mail.thegeekstuff.net (10.42.0.70) 56(84) bytes of data.\r\n64 bytes from mail.thegeekstuff.net (10.42.0.70): icmp_req=1 ttl=64 time=0.482 ms\r\n64 bytes from mail.thegeekstuff.net (10.42.0.70): icmp_req=2 ttl=64 time=0.532 ms<\/strong><\/pre>\nHope you like this blog<\/p>\n","protected":false},"excerpt":{"rendered":"
Domain Name Service (DNS) is an internet service that maps IP addresses to fully qualified domain names (FQDN) and vice versa. BIND stands for Berkley Internet Naming Daemon.
