Administering Centralized DNS Server

A Centralized DNS server can be managed on the DNS Server administration page. You can get to this page by clicking the IP address of a desired DNS server on the Centralized DNS Servers management page.

The DNS server administration page lists all Plesk servers assigned to this DNS server:


Column Name	Description
NS (network status)	Represents the network status of the Plesk server:		The server is presently online.
			The server is presently offline.
ID	Shows the ID number of the Plesk server. The ID number is given to each Plesk server automatically after registration in Plesk Expand and depends on the order of its registration. It means that the first Plesk server registered in Plesk Expand gets ID number 1, the second registered server – ID number 2 and so on.
Name	Provides the name of the Plesk server.
Group	Provides the name of the group this server belongs to. For more information about server groups, see Managing Groups of Plesk Servers in Chapter 3. Managing Plesk Servers.
IP address	Displays the default IP address of the Plesk server.
Plesk DNS Mode	Displays the mode the PleskDNS server is presently in. It can be either of the following four modes:	master	PleskDNS server acts as a primary (master) DNS server for all zones this Plesk server controls.
		hidden master	PleskDNS server acts as a primary (master) DNS server for all zones this Plesk server controls. However, it will be hidden from 'other' servers that need the DNS service. This will reduce the load on this server and make it more safe.
		slave	PleskDNS server acts as a secondary (slave) server. The primary server will be the Centralized DNS server this Plesk server is assigned to.
		off	The DNS service is offline on the PleskDNS. The Centralized DNS server this Plesk server is assigned to will act as a primary (master) one.
DNS Mode	Displays the mode the Centralized DNS server is presently in. It can be either of the following two modes:	master	Centralized DNS server acts as a primary (master) DNS server. All zones (direct and reverse ones) will be configured (or reconfigured) as master (primary) ones on this server. The content of these zones will be controlled by DNSC (DNS Controller).
		slave	Centralized DNS server acts as a secondary (slave) DNS server. All direct zones will be configured (or reconfigured) as slave (secondary) ones on this server.
Plesk Clients	Shows the total number of the Plesk clients registered on this server.
Domains	Shows the total number of the domains hosted on the server.
Platform	Displays the Plesk server version number, and the platform it operates on; this can be Linux, FreeBSD 4.9, or Windows 2003 platforms.
Keyword	Provides the server signal word, used for the automatic selection of this server for registering a new client on it, and for the fast search and identification of this server in the list.
L (login)		Allows you to log in to the desired Plesk server in the Plesk control panel as administrator. It takes you straight to this Plesk server control panel that will open in a separate browser window. Note: 1. Only administrator can use this function. 2. You will not be asked to enter login and password, as they were provided during the registration of a Plesk server this Plesk client is registered on.

The following operations can be performed with Plesk servers:

To assign a new Plesk server to this Centralized DNS server, click Add Plesk Server
To manage slave servers of this DNS server, click Slave DNS Servers
To edit SOA parameters of the DNS server, click SOA Parameters
To change the mode of a Plesk server or a number of servers, select the checkboxes next to these servers and click Switch mode. This takes you to the page where you can select the desired mode.
To proceed to the administration page of a certain Plesk server, click its name.
To sort Plesk servers by network status, select this status from the Net.status drop-down box (All, Unknown, Online or Offline) and click Search. To revert to the entire list of servers, click Show All.
To search for a particular Plesk server, enter its ID, name or keyword in the input fields provided, and click Search.
To refresh the data from certain Plesk server(s), select the corresponding checkbox(es) and click Reload. You will be taken to the Reload Server(s) page where you can select which data should be refreshed. This option might be useful if any changes were made to the Plesk server or several servers in Plesk Expand and you wish to refresh (reload) these servers yourself without having to wait for Plesk Expand to do that automatically.
Note: A server does not stop its operation during the reload.
To deassign a server/servers from this DNS server, select the corresponding checkbox(es) and click Deassign Selected. A confirmation page appears prior to deassign.
Note: The server(s) will be deassigned from this DNS server. However, they will still remain in Plesk Expand.
