Remote Servers Options

To display this screen:

  • Display the Options screen and click the Remote Servers tab.

Note: Many of the options on this screen are only available if License Manager has been run as an administrator.

Configure remote licensing servers.

To enable network licensing, check Use Remote Servers. Servers can then be added or removed.

When a remote server has been added, it can be disabled by clearing the check box by the relevant server name. You can also delete servers from the list, although this can't be undone.

Tip: If you're unsure if you should delete a server, don't. Uncheck it instead.

Servers can be added using an IPv4 or IPv6 format address. See Network Protocol Support.

Ambiguous Networks

If you are connecting to a server that exists on an ambiguous network (i.e. the network domain controller broadcasts each machine using both IPv4 and IPv6 addresses, you can choose which broadcast address you will use first in order to forge a connection between server and client.

For example, if you select Prioritize IPv6 over IPv4 if both provided? and an IPv6 network address is listed in the table below, the 'search' for a matching address on the local area network will be performed initially by comparing any specified IPv6 address (in the table) with IPv6 addresses broadcast by the server(s) on the network.

If a connection cannot be found with the specified IPv6 address, a subsequent attempt will be made using the IPv4 address that has been broadcast by the server, assuming a corrsponding IPv4 address is also specified in the table.

In addition to LAN connections, you can also connect to a hosted license web server by specifying its domain name (for example, HOSTED.LICENSES.MYDOMAIN.COM:1234). This facility is currently restricted to hosted licensing services as provided by Datamine.

To find out more about Datamine's license hosting service, contact your local Datamine representative.

Server Specification

When entering a new server configuration, consider the following:

  • The server name uses the format: MACHINENAME:PORT. MACHINENAME can either be the server name, or an IP address in either IPv4 or IPv6 format.
    • IPv4 example: 123.234.345.456.
    • IPv6 example: 3ffe:1900:4545:3:200:f8ff:fe21:67cf.

    See Network Protocol Support.

  • The port address is optional, with a default value of 43210 being used if the port is not specified.
  • Note that the network  Port is always specified in decimal format regardless of whether an IPv4 or IPv6 address format is being specified.
  • You cannot leave the port field blank. If you attempt to clear its contents, the 43210 default is reinstated.

You can deactivate or reactivate a listed server at any time by enabling or disabling the corresponding check box(es) on the left of the server address. Note that an attempt will be made to connect (and retrieve licenses from) all enabled remote servers during startup of License Services. The resulting license list will be grouped by each server, and server connection attempts will be made in a top-bottom list order.

Add a Server

To create a new server connection:

  1. Display the Remote Servers screen.

  2. Specify the network protocol to be used for data traffic between client and server using Prioritize IPv6 over IPv4 if both provided?:

    • If the Local Area Network is solely IPv4 or IPv6, this setting isn't important and can be ignored .

    • If your LAN is of a hybrid variety (that is, the network adapter of the server will broadcast both IPv6 and IPv4 variants of its address), you can choose which of these protocols you would prefer to use when specifying your server address(es).

      Check to prioritize IPv6 or uncheck to use the broadcast IPv4 format address.

    See "Ambiguous Networks", above.

  3. Click Add Remote Server to open an edit area in the Servers table:

  4. Either type in the name of the server, or click Broadcast....to search the local network for license servers. Any servers which are found are listed in the Servers table.

    Note: The Broadcast Timeout sets the time that the host waits for responses to a broadcast, preventing the system from 'hanging' if no response is received. This value can be adjusted to accommodate slow networks.

  5. Enter a Host name. See "Server Specification", above.

  6. Enter the Port (which must permit 2-way traffic). See "Server Specification", above.

  7. Click Apply.

    The Licenses list in the main License Manager table refreshes. License information is retrieved from the remote server(s) and listed, allowing you access to licenses that are not in use by others, and that you have permission to use.

    Tip: Once a server connection is established, you can close License Manager and launch your Datamine product. A license is retrieved either from local or remote (server) storage.

  8. Click OK to dismiss the Options screen.

Can't Connect?

Sometimes, it isn't possible to connect to a server. Here are some common reasons for a connection failure:

  • Server name, IP address or port number is incorrectly specified.

  • An IPv6 format address has been specified where the protocol is not supported by the network, or an IPv4 protocol has been specified but an IPv6 format is expected.

  • The relevant server is not broadcasting as a license server (see below).

  • Network problems are preventing a connection within the specified Timeout period.

  • The specified port is not currently configured to permit 2-way traffic for the user account(s) that are accessing it.

  • The license server is a virtual machine, not a physical machine. By default, License Services requires the provision of physical network hardware - contact your Datamine representative for guidance on using License Services on a virtual server.

  • Antivirus, anti-malware or similar local services are actively preventing a two-way connection between the source and destination machine.

  • The licensing services is no longer running on either the client or the server machine (more about License Service Options).

In most cases, the resolution is simple, but in situations involving network configuration problems, you will need to contact your Systems Administrator to ensure that you have the necessary network access rights. It is also important that the specified server name resolves to a valid machine on the network.

In the case of a connection failure, a screen displays which provides the following options:

  • Disconnect from this server – No further connection requests are made.

  • Work Offline – All remote server access is disabled. A local license must be available for you to continue using Datamine applications.
