We are going to install local DNS server on the Ubuntu server by using open source DNS tool Bing9.<\/p>\n\n\n\n
First we need to install bind9 on the Ubuntu:<\/p>\n\n\n\n
sudo apt install bind9 bind9-utils bind9-dnsutils -y<\/code><\/pre>\n\n\n\nSecond go to named.conf.local file under \/etc\/bind, and add below:<\/p>\n\n\n\n
\/\/\r\n\/\/ Do any local configuration here\r\n\/\/\r\n\/\/ Consider adding the 1918 zones here, if they are not used in your\r\n\/\/ organization\r\n\/\/include \"\/etc\/bind\/zones.rfc1918\";\r\n\r\nzone \"example.com\" {\r\n type master;\r\n file \"\/etc\/bind\/db.forward.com\";\r\n};\r\n\r\nzone \"100.10.10.in-addr.arpa\" {\r\n type master;\r\n file \"\/etc\/bind\/db.reverse.com\";\r\n};\r\n\r<\/code><\/pre>\n\n\n\nThen we are going to copy default conf files with command cp db.local to db.forward.com and cp db.127 to db.reverse.com. when it’s done update below conf files: <\/p>\n\n\n\n
\/\/ db.forward.com\r\n; BIND data file for local loopback interface\r\n;\r\n$TTL 604800\r\n@ IN SOA ns.dnsserver.com. root.localhost.
