Donating Licenses via Interserver Connections

In an anti-virus network with several Dr.Web Servers, an optional number of licenses can be donated between Dr.Web Servers for a certain period of time.

To be able to donate the licenses between Dr.Web Servers, please configure inter-server connections as described in section Setting Connections between Several Dr.Web Servers.

•The parent Dr.Web Server donates licenses, the child Dr.Web Server receives licenses according to the license allocation settings (cannot be changed).

•Donating licenses between peer Dr.Web Servers. In this case, set the Send flag in the Licenses section of the connection settings for the Dr.Web Server that donates licenses; and set the Receive flag for the Dr.Web Server that receives licenses.

1.Open the Control Center of the Dr.Web Server on the anti-virus network that will donate licenses to neighboring Dr.Web Servers.

2.Select Administration in the main menu of the Control Center, then select License Manager in the control menu.

3.Add a license key, as described in the License manager section, if no key has been added earlier. The number of licenses in the key must correspond to the total number of stations protected by both this Dr.Web Server and all Dr.Web Servers that will get licenses from this key.

Generally, you can have only one license key, the licenses from which will be allocated to all Dr.Web Servers.

4.Count the number of licenses that you can donate to neighboring Dr.Web Servers using this key. Note that neighboring Dr.Web Servers can also donate a number of licenses to other Dr.Web Servers. In this case, you need to donate a total number of licenses from the key installed on the parent Dr.Web Server that is equal to the number of licenses to be allocated further along the chain. Please note, that the parent Dr.Web Server will not be able to use the donated licenses until the end of the license allocation period and their return.

5.Configure the donation of licenses to neighboring Dr.Web Servers from the license key, as described in the License Manager section.

In the License expiration date field, specify the expiration date for the donated licenses. The donation period can be either less than or equal to the validity period of the license itself. At the end of the specified period, all licenses will be reclaimed from neighboring Dr.Web Servers and returned to the pool of available licenses associated with the initial license key. If necessary, you can edit this period at any time, as described in the License Manager section.

6.If necessary, the settings of license donation can be changed. For this, open the Dr.Web Server configuration section.

7.On the Licenses tab, configure the following settings for the Dr.Web Server that donates licenses:

•Automatic renewal period of donated licenses—a period of time for which licenses originating from the key on this Dr.Web Server are donated. After this period, the donated licenses are automatically renewed for the same period. Automatic renewal takes place before the expiration of the license donation period specified in the License Manager at step 5.
This mechanism ensures that the licenses are returned to the parent Dr.Web Server in case the child Dr.Web Server is shut down and can't return the donated licenses.

•License synchronization period—an interval at which the information about donated licenses is synchronized between Dr.Web Servers. License synchronization is used to verify that the number of licenses donated by the parent Dr.Web Server and received by the child Dr.Web Server is the same. This mechanism helps to detect malfunctions and fraud during licenses donation.

•Period of report creation—an interval at which Dr.Web Server generates reports on the license keys used. If a report on license usage is generated by a child Dr.Web Server, it is then sent to the main Dr.Web Server. Created reports are additionally sent at each connection to Dr.Web Server (including its restart), and also when the number of donated licenses is changed at the main Dr.Web Server. The setting is specified on the parent Dr.Web Server but is also used by the child Dr.Web Server when sending the reports.

•Period of active stations counting—a period of time during which the number of active stations will be counted and then included in the license usage report. If set to "0", all stations will be included in the report regardless of their activity status. The setting is specified on the parent Dr.Web Server but is also used by the child Dr.Web Server when sending the reports.

1.Open the Control Center of the anti-virus network Dr.Web Server that will receive licenses from a neighboring Dr.Web Server.

2.If necessary, change the license allocation settings. To do this, open the Dr.Web Server configuration section.

3.On the Licenses tab, specify the Interval for preliminary renewal of accepted licenses—a time interval before the expiration of the scheduled renewal period for the license received from a neighboring Dr.Web Server. Starting from this period this Dr.Web Server will request the preliminary automatic renewal of these licenses.

The use of this option depends on the type of connection selected in the Connection options setting in the configuration of the neighboring Dr.Web Server (see Setting Connections between Several Dr.Web Servers):

•For the periodic connection: if the reconnection period specified in the connection options is greater than the Automatic renewal period of donated licenses specified on the donor Dr.Web Server, then the automatic renewal of these licenses will be initiated before the Automatic renewal period of donated licenses expires.
