Licenses Propagation via Interserver Connections

In anti-virus network with several Servers, the optional number of licenses can be propagated between the Servers for a certain time period.

To be able to propagate the licenses between the Servers, you must configure interserver connections as described in the Setting Connections between Several Dr.Web Servers section.

•The parent Server donates licenses, the child Server receives licenses according to the settings of the connection for licenses propagation (cannot be changed).

•Propagating licenses between peer Servers. In this case, for the Server that donates licenses, in the neighbor connection settings, in the Licenses section, the Send flag must be set; and for the Server that receives licenses—the Receive flag.

1.Open the Control Center of the anti-virus network Server that will donate licenses to neighbor Servers.

2.In the main menu of the Control Center, select the Administration item, in the control menu, select License Manager.

3.Add a license key, as described in the License manager section, if a key has not been added earlier. The number of licenses in the key must correspond to the total number of served stations by both this Server and all Servers that will get licenses from this key.

In the common case, you can have only one license key, the licenses from which will be propagated between all the Servers.

4.Count the number of licenses that you can donate to neighbor Servers from this key. Please consider that neighbor Servers also can donate the part of licenses to other Servers. In this case, you must donate from the key of the parent Server the summary number of licenses that are planned to propagate further along the chain. Also, please consider that the parent Server will not be able to use the propagated licenses till the end of propagation period of these licenses and their return.

5.Configure the propagation of licenses to neighbor Servers from the license key, as described in the License Manager section.

In the License expiration date option, specify the final expiration date of licenses donation. Donation period can be either less than the validity of the license itself, or equal to it. At the end of the specified period, all licenses will be called back from the neighbor Servers and get back to the list of free licenses of the initial license key. If necessary, you can edit this period at any time, as described in the License Manager section.

6.If necessary, change the settings of licenses propagation. For this, open the Dr.Web Server configuration section.

7.On the Licenses tab, specify the following settings for the Server that donates licenses:

•Automatic renewal period of donated licenses—time period for which licenses are donated from the key on this Server. After this period, the donated licenses are automatically renewed for the same period. Automatic renewal is performed before the expiration of the license propagation period specified in the License Manager at the step 5.
This mechanism provides returning of licenses to the parent Server if the child Server will be turned off and will not be able to return donated licenses.

•License synchronization period—interval for synchronizing information about donating licenses between Servers. Licenses synchronization allows to detect that the number of licenses donated by the parent Server and received by the child Server are not equal. This mechanism allows to detect malfunctions and cases of forgery during licenses donation.

•Period of report sending on license usage—period of report sending by neighbor Servers on usage of donated licenses to the parent Server. The option is specified on the parent Server but is used by the child Server when sending the reports.

•Period of active stations counting for the license report—period for counting the number of active stations for sending the report on license usage. The option is specified on the parent Server but is used by the child Server when sending the reports.

1.Open the Control Center of the anti-virus network Server that will receive licenses from neighbor Server.

2.If necessary, change the settings of licenses propagation. For this, open the Dr.Web Server configuration section.

3.On the Licenses tab, specify the Interval for preliminary renewal of accepted licenses—time interval before the expiration of the licenses automatic renewal period, received from a neighbor Server, starting from which this Server requests the preliminary automatic renewal of these licenses.

•For the periodic connection type: if the reconnection period specified in the neighbor settings is greater than Automatic renewal period of donated licenses specified on the Server that donated licenses, when automatic renewal of these licenses will be initiated earlier than the Automatic renewal period of donated licenses expires.
