Licenses on a license server
By default, clients can access all Sentinel license servers running in the same subnet. If you operate several subnets or want to restrict the access of clients to a license server, you have to control the access accordingly.
Restrict access on the server side
If only specific clients should be allowed to access a Sentinel license server, you have to restrict the access accordingly.

- Licensing options
  The licensing option determines the number of users who can access PLA 3.0 at the same time. It also determines the number of computers on which you can install PLA 3.0.
- Information packages
  Information packages play a central role in the installation and licensing process. They contain key data required to get PLA 3.0 up and running in your environment.
- Activate your license
  To activate your PLA 3.0 license, you install a software key on the computer or license server that should hold the PLA 3.0 license. Activating the PLA 3.0 license automatically activates the license keys for your add-ons.
- Transfer your license
  PLA 3.0 licenses are tied to the computer to which you apply the vendor-to-customer (.v2c) file. Before you change the hardware or operating system of this computer, you have to temporarily transfer the license to a different computer.
- Manage existing licenses
  Learn how to increase the number of concurrent users, replace a hardware key with a software key, or cross-upgrade from a Seat license to a Concurrent use license.
- Licenses on a license server
  By default, clients can access all Sentinel license servers running in the same subnet. If you operate several subnets or want to restrict the access of clients to a license server, you have to control the access accordingly.
  - Configure licensing across subnets
    If a Sentinel license server and its clients are running in different subnets, you have to allow clients to broadcast across the whole network.
  - Restrict access on the server side
    If only specific clients should be allowed to access a Sentinel license server, you have to restrict the access accordingly.
  - Restrict access on the client side
    If a client should only be able to access specific Sentinel license servers, you have to restrict the access accordingly. You can also configure a sequence according to which a client should connect to servers.
- Legacy protection keys
  We recommend software keys for license activation. However, we also support legacy protection keys, namely hardware-based Sentinel protection keys and hardlock keys.
Administration
Details on system administration tasks such as setup and maintenance of databases and add-ons, user accounts, access rights, and migration and update procedures.
Regulatory compliance
PLA 3.0 supports you in achieving compliance with regulations such as ISPE GAMP^® 5 and 21 CFR Part 11. It also provides options to validate PLA 3.0 in your environment.

Restrict access on the server side

If only specific clients should be allowed to access a Sentinel license server, you have to restrict the access accordingly.

Procedure

To restrict access on the server side:

On the license server, open the PLA License Control Center in a browser at http://127.0.0.1:1947.
Go to Configuration. On the Access from remote clients tab, make sure the Allow access from remote clients checkbox is selected. Otherwise, clients are not allowed to obtain PLA 3.0 licenses from this license server.
To configure the access of clients to the license server, add respective entries to the Access restrictions text box. Add one entry per line.
- To grant a client access, enter allow=<IP> or allow=<hostname>.
- To deny a client access, enter deny=<IP> or deny=<hostname>.
Note: The order of the entries determines their priority, entries higher up in the list take precedence.
