DNS Server Configuration

Abstract

DNS stands for “Domain Name System”. It allows you to specify a machine by its name instead of its IP address. This wizard allows you to setup a basic DNS server, master or slave.

Make sure you have a FQDN host name set for your system, otherwise the DNS wizard will refuse to start up. Please refer to the section called “Network and Internet Connection Management”, for information on how to set the system's host name. You are given the option to run one of four wizards:

Master DNS Server

This wizard will set up your machine as a plain DNS server. The first step allows you to provide the address of an external DNS server to which will be forwarded the requests that the local server cannot answer. It is generally the address of your ISP's DNS server.

During the second step you will be able to specify domain names for lookups. For example if you request the IP of a machine called kenobi, the server will add the domain names you add here to perform the request.

Slave DNS Server

This wizard will configure your machine as the slave server of another master DNS server. You only need to supply the IP address of the master server for the slave to mirror. Then clients can be configured to query both servers: if the master fails, the slave will take relay.

Add Host in DNS

If your machine is a master DNS server, you'll be able to declare all the machines with static addresses on your network so that the DNS server can answer requests about them.

Remove Host in DNS

This is used to remove a DNS entry previously entered with Add Host in DNS.

[Note]Note

Both the Add Host in DNS and Remove Host in DNS wizards will only work if your machine is set up as a master DNS server.
