Once the Sentinel run-time driver is installed and the network license is connected, the CHARON VM can be started on any appropriate host on the LAN network segment.

...


Info

CHARON-AXP/VAX version 4.7 build 171-01 introduced a change with respect to network licenses. In previous versions of CHARON-AXP/VAX a network license controlled the maximum number of client host systems and CHARON instances per host system (station/instance mode).

In the current CHARON-AXP/VAX versions a network license controls the maximum overall number of active instances, which can be distributed across client host systems according to the preference of the customer.

...

Software licenses

The CHARON-VAX / CHARON-PDP Software License (SL) is a "virtual" key with exactly the same functionality as the hardware dongle. It does not require any hardware but the installation of the Sentinel run-time environment is required.

Note

The Software Licenses (SL) are best suited for stable environments because their correct function depends on certain characteristics of the host system. Changing any of these characteristics will invalidate the license.

  • If the CHARON host runs on real hardware, the software licenses are by default tightly bound to the hardware for which they were issued. If major hardware characteristics of the system are changed, the license will be disabled.
  • If the CHARON host runs in a virtual environment (e.g. VMware), software licenses are normally bound to the virtual machine ID and a set of additional characteristics of the virtual machine. If any of these parameters are changed, the license will be disabled.
In special cases, a software license can also be bound to the fully qualified domain name (FQDN) of the host system. If this name changes
  • , the license will be disabled.

For a more detailed description of the restrictions, please refer to Software Licensing restrictions or contact your Stromasys representative.

Software licenses are always network-wide on Windows, so they behave the same way as Network HASP keys.

Multiple licenses configuration and backup license

For any type of licensing, a CHARON VM can use only one valid ("active") license (of given vendor code) at a time.

The "HASP License details" utility (it can be started from CHARON Virtual Machines Manager) displays a range of available licenses but note that, by default, a CHARON VM may use any of them as the "active" one - unless it is directly specified by the "license_key_id" parameter (see below). The utility provides the license numbers and ID / IP addresses of the hosts where the licenses are installed.

Warning

A CHARON VM cannot: 

  • check all the available license keys / software licenses,
  • choose one,
  • automatically switch from one key to another (except when the backup license is specified in its configuration file).

The general recommendation is to avoid the usage of multiple keys in one network segment. Use only one locally installed license per host or one network license per local network segment containing several CHARON hosts.

When needed, it is possible to use a special parameter in the CHARON VM configuration files to specify exactly which license must be used by each particular CHARON VM:

ParameterTypeValue
license_key_id[N], N=0 or 1Numeric

A number (decimal Sentinel key ID) that specifies regular (N=0) and backup (N=1) license keys to be used by the CHARON VM.

Example:

set session license_key_id[0]=1877752571
set session license_key_id[1]=354850588

It is also possible to specify both regular and backup key in one line.

Example:

set session license_key_id[0]=1877752571 license_key_id[1]=354850588

Depending on the presence of the regular and/or backup license key IDs in the configuration file, the CHARON VM behaves differently:
 

  1. No keys are specified
    The CHARON VM behaves as usual (performs unqualified search for any suitable key). If no keys are found, the CHARON VM stops.

  2. Both keys are specified
    The CHARON VM performs qualified search for regular license key. If it is not found, the CHARON VM performs qualified search for backup license key. If it is not found, the CHARON VM stops.

  3. Only regular key is specified
    The CHARON VM performs qualified search for regular license key. If it is not found, the CHARON VM performs unqualified search for any suitable key. If it is not found, the CHARON VM stops.

  4. Only backup key is specified
    The CHARON VM behaves as usual (performs unqualified search for any suitable key). If no keys are found, the CHARON VM stops.

This parameter also specifies the license which will be used as backup if the active license expires.

Disable remote keys access 

A helpful feature of the Sentinel Admin Control Center is the ability to disable access to remote keys. If the network key is installed locally, access to the key from remote hosts can be disabled. The following examples demonstrate how this can be done.

Removing CHARON-VAX / CHARON-PDP software licenses

The following procedure must be applied to remove the software license (SL):


  1. Open the CHARON Virtual Machines Manager, switch to the "Host Information & Utilities" tab and press the "Sentinel Admin Control Center" button:
    StatuscolourRedtitleTO DO
    or - alternatively - start any web browser on this system and go to the http://localhost:1947 page.

  2. In the "Sentinel HASP Admin Control Center" (ACC), select the "Sentinel Keys" option in the left pane and locate the target "Sentinel SL AdminMode" license.

  3. Press the "Certificates" button at the right side of the SL description:


    .

  4. Note the name of the correspondent certificate and path to the certificates base in the "Certificates" section:


    .
  5. Remove the corresponding certificate file in the "C:\Program Files\Common Files\SafeNet Sentinel\Sentinel LDK\installed\68704" folder.  In the example above the file to remove is "C:\Program Files (x86)\Common Files\SafeNet Sentinel\Sentinel LDK\installed\68704\387285561437702475_base.v2c".

  6. Reboot the CHARON host.

  7. Start the "Sentinel HASP Admin Control Center" (ACC) again to ensure the SL has been removed.
