Domains



Description

The domain name system (or DNS) is a system allowing to establish a link between an IP address and a host of a domain. (see DNS on wikipedia)

If you already have a site accessible by an project.tuxfamily.org address type and you want to migrate to an project.org address type, then you may be interested in this page: How to change from project.tuxfamily.org to project.org address?

Requirements

DNS Creation

good to know

You can register your domain using the registrar of your choice. Just know that TuxFamily have all our domains registered by gandi and that we really like their services. We are now going to consider for the rest of this page that you own the domain myproject.org.

Some simple steps

  • log into the panel
  • select the group that will receive your new DNS
  • Use the "create" button in the DNS section of the menu.
  • Fill up the "domain name" field. In our example, myproject.org
  • Then, as usual, you will have to provide a description for our dear moderators ;)

How to configure and manage your domain name

On your registrar web interface

Depending on the registrar you have chosen for your domains, the configuration method will change. This is why we can't provide detailed steps for this configuration. You may have to educate yourself using your registrar's help pages. You will need those informations :

  1. DNS Server 1 : ns1.tuxfamily.net
  2. DNS Server 2 : ns2.tuxfamily.net

How to manage your domain using the panel

A Type Records

An A record or address record maps a hostname to a 32-bit IPv4 address

AAAA Type Records

An AAAA record or IPv6 address record maps a hostname to a 128-bit IPv6 address

MX Type Records

An MX record or Mail exchanger record is a type of resource record in the Domain Name System (DNS) specifying how Internet e-mail should be routed. MX records point to the servers that should receive an e-mail, and their priority relative to each other.

If your registrar provides Email service, you might want to change the MX record to point to their mail server. Consult your registrar's Email services documentation for the specific name of the server to use.

CNAME Type Records

A CNAME record or canonical name record is an alias of one name to another. The A record to which the alias points can be either local or remote - on a foreign name server.

This is useful when running multiple services (like an FTP and a webserver) from a single IP address. Each service can then have its own entry in DNS (like ftp.example.com. and www.example.com.)

For Email services, you might want to create CNAME records for pop,imap, or smtp servers.

NS Type Records

An NS record or name server record maps a domain name to a list of DNS servers authoritative for that domain. Delegations depend on NS records.

SRV Type Records

An SRV record or Service record is a category of data in the Internet Domain Name System specifying information on available services.

TXT Type Records

A TXT Record allows an administrator to insert arbitrary text into a DNS record. For example, this record is used to implement the Sender Policy Framework and DomainKeys specifications.

My group's rights

This object can be shared with the rest of your group using the ACL

How to delete it

  • Login on the panel
  • select the group which owns your dns
  • In the "Domain Names for your_project" box, select "Go to Administration"
  • scroll down to "Delete this domain name from the VHFFS platform" , change the radio-button from No to Yes
  • Press the delete button.

Tricks and tips

  • If you set up records (e.g. MX or CNAME records) pointing to other domains, then don't forget the dot at the end of the domain name. The dot is the mark which indicates that this is the end of the domain. Otherwise, the address you specified will end up being concatenated with your domain (e.g. ftp.yourdomain.org will point to ftp.otherdomain.net.yourdomain.org), and you'll be left wondering why it's not working.
  • If you wish to have a website on this domain name, you have to ask for the corresponding web area.
