Software licenses

The CHARON-VAX / CHARON-PDP Software License is a "virtual" key with exactly the same functionality as the hardware dongle.

The CHARON-VAX / CHARON-PDP Software License does not require any hardware but it requires installation of the Sentinel run-time environment.

Note

Software licenses 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, 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, 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 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

CHARON VM cannot: 

  • check all the available license keys / software licenses,
  • choose one,
  • automatically switch from one key to another.

The general recommendation is to avoid 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 VM hosts.

When needed, it is possible to use a special parameter in the CHARON VM configuration file 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 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, CHARON VM behaves differently:
 

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

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

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

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

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 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.
