DNS, LDAP and JMS on Linux – Smoother And Easier!

Linux based DNS server is making the networking system smoother and easier. The users can set up the DNS server for several reasons such as: better Internet domain Support. If the users have a domain name and they are operating email, FTP and other Web server, then implementing the DNS server is a more essential to respond to the resolution queries that allows the users to access your server.

It is also making the communication process more effective. It is also the best alternative than any other expensive server designs. DNS on the Linux is offering the users unique and own domain name to secure their important data on their server. Former king of the centralized authentication systems was or Information System or NIS. NIS is the simple & well supported technology, however it is as well insecure.

By same token, pieces of DNS directory database (“zones”) are been stored, and kept, on a lot of different DNS servers situated around Internet. In case, you to find telephone number for the person in Poughkeepsie, you would need to look in Poughkeepsie phone book. In case, you would like to find IP address of www server in some domain.com domain, you would need to query DNS server, which stores DNS records for this domain.

IP address of server’s NIC linked to Internet needs to match whatever address is there in DNS database. The dynamic DNS gives way around for the home servers that we can see later. Whenever you would like to browse at www.their-domain.com the DNS server (one you specify in TCP or IP configuration on the desktop computer) likely will not have the DNS record for their domain.com domain thus it needs to contact DNS server, which does. Whenever the DNS server contacts DNS server, which has DNS records (it is referred as “resource records” and “zone records”) for the -domain.com DNS server gets IP address of www server as well as relays this address back to desktop computer.
