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.
The propagation is available for the following types on neighbor connection: •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 section, the flag must be set; and for the Server that receives licenses—the flag. To configure the Server that will donate licenses 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 item, in the control menu, select . 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 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 section. 7.On the tab, specify the following settings for the Server that donates 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. •—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 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 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. 8.Save the changes and restart the Server. To configure the Server that will receive licenses 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 section. 3.On the tab, specify the —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. Using this option depends on the type of connection selected in the setting in the neighbor Servers 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 specified on the Server that donated licenses, when automatic renewal of these licenses will be initiated earlier than the expires. •For the permanent connection: this option is not used. 4.Save the changes and restart the Server. |
