In anti-virus network with several Dr.Web Servers, the optional number of licenses can be propagated between Dr.Web Servers for a certain time period.
|
To be able to propagate the licenses between Dr.Web Servers, you must configure interserver connections as described in the Setting Connections between Several Dr.Web Servers section. |
The propagation is available for the following types on neighbor connection:
•The parent Dr.Web Server donates licenses, the child Dr.Web Server receives licenses according to the settings of the connection for licenses propagation (cannot be changed).
•Propagating licenses between peer Dr.Web Servers. In this case, for the Dr.Web Server that donates licenses, in the neighbor connection settings, in the Licenses section, the Send flag must be set; and for the Dr.Web Server that receives licenses—the Receive flag.
To configure Dr.Web Server that will donate licenses
1.Open the Control Center of the anti-virus network Dr.Web Server that will donate licenses to neighbor Dr.Web 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 Dr.Web Server and all Dr.Web 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 Dr.Web Servers.
4.Count the number of licenses that you can donate to neighbor Dr.Web Servers from this key. Please consider that neighbor Dr.Web Servers also can donate the part of licenses to other Dr.Web Servers. In this case, you must donate from the key of the parent Dr.Web Server the summary number of licenses that are planned to propagate further along the chain. Also, please consider that the parent Dr.Web 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 Dr.Web 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 Dr.Web 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 Dr.Web Server that donates licenses:
•Automatic renewal period of donated licenses—time period for which licenses are donated from the key on this Dr.Web 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 Dr.Web Server if the child Dr.Web 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 Dr.Web Servers. Licenses synchronization allows to detect that the number of licenses donated by the parent Dr.Web Server and received by the child Dr.Web Server are not equal. This mechanism allows to detect malfunctions and cases of forgery during licenses donation.
•Period of report creation—period of reports creation by Dr.Web Server on license keys it uses. If a report on license usage is created by a child Dr.Web Server, then after it is created, this report is sent to the main Dr.Web Server. Created reports are additionally sent at each connection (including restart) of Dr.Web Server, and also at changing the number of donated licenses at the main Dr.Web Server. The option is specified on the parent Dr.Web Server but is used also by the child Dr.Web Server when sending the reports.
•Period of active stations counting—period for counting the number of active stations for creating the report on licenses usage. The 0 value prescribes to count all stations in the report not depending on their activity status. The option is specified on the parent Dr.Web Server but is used also by the child Dr.Web Server when sending the reports.
8.Save the changes and restart Dr.Web Server.
To configure Dr.Web Server that will receive licenses
1.Open the Control Center of the anti-virus network Dr.Web Server that will receive licenses from neighbor Dr.Web 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 Dr.Web Server, starting from which this Dr.Web Server requests the preliminary automatic renewal of these licenses.
Using this option depends on the type of connection selected in the Connection options setting in the neighbor Dr.Web Server's configuration (see Setting Connections between Several Dr.Web Servers):
•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 Dr.Web Server that donated licenses, when automatic renewal of these licenses will be initiated earlier than the Automatic renewal period of donated licenses expires.
•For the permanent connection: this option is not used.
4.Save the changes and restart Dr.Web Server.
