Server access control

Reserved licenses

In the Reserved licenses section, you can reserve ibaHD-Server client licenses and ibaQPanel licenses for specific computers in the network. Licenses that you reserve are considered used even if the client is not connected.

Since the license model of ibaHD-Server works with free (floating) licenses, any client that wants to access the server can use a free license. However, this entails the risk that clients that absolutely require licensed functions will no longer find a free license if other clients were "faster" and have used all available licenses.

You can now use the reservation to guarantee that the clients that absolutely require server access for certain licenses also receive these licenses.

You must identify the computer by its name. You can also reserve several licenses for one computer if several instances of the ibaHD-Server client are to run on the same computer. Reserved licenses can only be used by computers that are on the list.

Clients that are not in the list can only use generally available licenses.

In the Client connections section, at the bottom of the dialog box, the available ibaHD-Server client licenses and ibaQPanel licenses are displayed.

For reserved licenses for clients that are not currently connected to the server, the row is marked with a grey background.

Enable reserved licenses

If you enable this option, the allocation of licenses is regulated according to the reservations. If you disable this option, all licenses of the server become available again.

Reserve license

1. Click the  button to add a new line. A computer name is then immediately displayed in the Client name column if there are active clients in the network. The first row is usually the name of the server computer itself.

2. Select the desired client from the list of available clients.

3. Then place a checkmark in the selection fields of the desired license(s).

Cancel reservation

1. Select the table row of the client for which you no longer require a reservation.

2. Click the  button.

Server access filter

In the Server access filter area, you can specify which clients are allowed to connect to the server. To do this, enter the IP address ranges for the permitted clients.

Only allow client connections with an IP address..

If you enable this option, only connections from clients located in one of the IP address ranges in the table below are permitted. If you disable this option, the accesses are not filtered.

Note
	If this option is enabled but no IP address range has been entered in the list, then access to the server is only possible via local clients running on the server computer.

Add address range for filters

1. Click the  button to add a new line. A default name is provided in the Range name column, which you can change as required.

2. Enter the start address of the permitted range in the From address column.

3. Enter the end address of the permitted range in the To address column.

Delete filter range

1. Select the table row of the range for which you no longer want to filter.

2. Click the  button.

Save configuration

The configuration of the server access can be saved in an ibaHD-Server project, see Managing ibaHD-Server projects.

If a project is to be loaded that contains a server access configuration, the user is asked whether the server access configuration should also be loaded.
