CHARON-AXP for Linux licensing
Table of Contents
General description
The CHARON-AXP products are protected by licenses, issued by STROMASYS for each customer individually. The CHARON-AXP license defines a set of HP Alpha emulators allowed to run.
The license is implemented in the form of a hardware dongle (a Sentinel HASP key) or a software license bound to the hardware. Please be careful with your license key. In case of loss or damage, CHARON-AXP will not run or start unless the license key is replaced. For extra protection, STROMASYS recommends the use of a backup license key (purchased separately) that can replace the main license key for a restricted period of time. It is possible to specify the backup license in the CHARON-AXP configuration file to prevent CHARON-AXP from stopping in case its main license is no longer accessible.
The CHARON-AXP license is read upon the start of each instance of CHARON-AXP and at a specified interval (defined by the license content) during the emulated system execution. If CHARON-AXP detects the absence (or malfunction) of the license key / software license, CHARON will try to use a backup license (if specified in the configuration file). If the license is not available / not specified, CHARON displays a warning message in the log file requesting license key reconnection or software license reactivation. If the license is not reconnected within a given period of time (the check interval), CHARON-AXP exits.
Note that if the time-restricted license is used and it expires, CHARON-AXP tries to find its replacement automatically and, if found, CHARON-AXP proceeds using the replacement license.
The CHARON-AXP software license is not distributed in case of Proof-of-Concept and evaluation installations. Only hardware dongles are used in this case.
It is important to connect the HASP license keys to the computer from time to time even if CHARON-AXP is not used. The keys contain a built-in accumulator that needs to be charged. If the accumulator is completely discharged, the license key can be fatally damaged.
Update of the CHARON-AXP license can be performed on the fly without stopping CHARON-AXP. At the next license check, CHARON-AXP will use the updated license normally.
The following sections list all the main parameters of the CHARON-AXP licensing mechanism.

CHARON-AXP licensing models
CHARON-AXP licensing models are divided in 3 groups:
Regular Sentinel HASP keys
This is most common way of CHARON-AXP licensing, the CHARON-AXP license is embedded in a Sentinel HASP dongle. This license is available only on the host where the dongle is physically installed.
The CHARON-AXP installation procedure takes care of the Sentinel HASP run-time (driver) installation. Once the CHARON-AXP product has been installed, it is possible to plug-in the regular license key and proceed with CHARON-AXP usage without additional configuration steps.
The number of CHARON-AXP instances allowed to run on a particular host may be restricted by the license content (see above).
Network Sentinel HASP keys
The Network Sentinel HASP key (red dongle) can be shared between several hosts running CHARON-AXP including the host on which the network license is installed.
If CHARON-AXP is installed on the host where the network key is connected, no additional steps are required. The Sentinel driver is activated as part of the CHARON-AXP installation. If the host does not have CHARON-AXP installed, the host can still distribute the connected network license to CHARON-AXP instances running on other hosts. In this case the Sentinel driver must be installed on the host manually.
The Sentinel run-time driver is distributed as a separate RPM package in the CHARON-AXP kit. Please see the "License installation" section of this chapter for details.
Once the Sentinel run-time driver is installed and the network license is connected, CHARON-AXP can be started on any appropriate host on the LAN network segment. 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-AXP Software License is a "virtual" key with exactly the same functionality as the hardware dongle.
The CHARON-AXP Software license does not require any hardware but it requires the installation of the Sentinel run-time environment.
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, 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), the 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.
For a more detailed description of the restrictions, please refer to the Software Licensing restrictions article or contact your Stromasys representative.
Software licenses are always network-wide on Linux so they behave the same way as Network HASP keys.
Multiple licenses configuration
For any type of licensing, CHARON-AXP can use only one valid ("active") license (of given vendor code) at a time.
The "hasp_srm_view" utility displays the "active" license by default and is able to display all available licenses with the "-all" parameter. It is also possible to check some specific license by its number using the "-key" parameter.
The utility provides the license number and ID / IP address of the host where the active license is installed.
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-AXP hosts.
When needed, it is possible to use a special parameter in the CHARON-AXP configuration file to specify exactly which license must be used by each particular instance of CHARON-AXP:
Parameter | license_key_id | |
---|---|---|
Type | Text string | |
Value | A set of Sentinel Key IDs that specifies the license keys to be used by CHARON. It is also possibly to use a keyword "any" to force CHARON to look for a suitable license in all available keys if the license is not found in the specified keys. Example:
Based on the presence of this parameter in the configuration file, CHARON behaves as follows:
If the keyword "any" is specified then if no valid license has been found in the keys with specified ID’s all other available keys are examined for valid license as well. The order in which keys are specified is very important. If a valid license was found in the key which ID was not the first one specified in configuration file, then available keys are periodically re-scanned and if the key with the ID earlier in the list than the current one is found CHARON tries to find a valid license there and in case of success switches to that key. |
License installation
Installation of Regular and Network license keys
Installation of CHARON-AXP regular and network licenses consists of:
Installation of the Sentinel run-time environment on the CHARON-AXP host (regular and network keys) or on the host that will distribute CHARON-AXP licenses over a local network segment (network key only). The Sentinel software (the “aksusbd” RPM package) is installed automatically by CHARON-AXP for Linux.
Physical connection of the HASP license dongle to the CHARON-AXP host or to the host distributing the CHARON-AXP license over the local network segment.
When manual installation of Sentinel run-time is required (in the case of the network license server that does not have CHARON-AXP installed), open the CHARON-AXP kit folder and proceed the following way:
|
In case of network-wide license (red dongle) do the following:
- On the server side (where the network license will reside): open port 1947 for both TCP and UDP
- On the client side, if broadcast search for remote licenses is to be used, UDP traffic from port 1947 of the license server to ports 30000-65535 of the client must be permitted.
- Both on server and client sides: setup default gateway
Please consult with your Linux User's Guide on details.
If stricter firewall rules are required, it is possible to open the ports 30000-65535 and 1947 only for the "/usr/sbin/hasplmd" daemon.
Some additional packages may be needed in certain cases, for example "glibc.i686"
Replacement of currently installed Sentinel run-time
Replacement of currently installed Sentinel Run-time may be needed in case of:
- Upgrade to a newer version of CHARON-AXP
- Installation of a specific CHARON-AXP license Run-time provided by STROMASYS
Remove the current run-time (and the package "charon-license-<...>.rpm" containing the run-time customization) with the command
# rpm --nodeps -e aksusbd charon-license-<...>
Change to the directory where the new run-time RPM resides (along with the corresponding "charon-license-<...>.rpm" customization package) and issue the command:
# rpm --nodeps -ihv aksusbd<…>.rpm charon-license-<...>.rpm
Installation and update of CHARON-AXP Software License or HL/HASP dongle License
CHARON-AXP Software Licenses (SL) can be installed / updated according to the procedure described below.
Install CHARON-AXP together with Sentinel run-time (Sentinel run-time is an essential part of CHARON-AXP for Linux distribution)
Reboot the host system
- Connect the HASP dongle to the host system (in case of update of a license in a dongle)
Collect the CHARON-AXP host fingerprint file (".c2v") - in case of first installation of a Software License:
# hasp_srm_view -fgp my_host.c2v
or collect the ".c2v" file in case a Software License is already installed or the connected HL/HASP dongle needs updating:
# hasp_srm_view -c2v current_license.c2v
Send the ".c2v" file ("my_host.c2v" / "current_license.c2v" in the examples above) to STROMASYS
Receive a ".v2c" file in return and put it somewhere on the CHARON-AXP host.
Start any web browser on this system and go to http://localhost:1947 to access the "Sentinel HASP Admin Control Center" (ACC) or configure ACC for remote access (see the details below).
In ACC, under the Options menu, select Update/Attach, "" for the "*.v2c" file and then "".
Ensure that the license appears in the “
” menu.
Alternatively it is also possible to use "hasp_update" command line utility for applying the ".v2c" file.
The content of the installed software license is not shown by the Sentinel HASP Admin Control Center. To see it please run the "hasp_srm_view" utility from the local console or configure remote access according to the instructions given in the "hasp_srm_view" utility section.
In case of network-wide software license do the following:
- On the server side (where the network license will reside): open port 1947 for both TCP and UDP
- On the client side, if broadcast search for remote licenses is to be used, UDP traffic from port 1947 of the license server to ports 30000-65535 of the client must be permitted.
- Both on server and client sides: setup default gateway
Please consult with your Linux User's Guide on details.
If stricter firewall rules are required, it is possible to open the ports 30000-65535 and 1947 only for the "/usr/sbin/hasplmd" daemon.
License management
CHARON-AXP license management is performed by the Sentinel Admin Control Center and specific utilities. They are described in the sub-sections below.Sentinel Admin Control Center
General Description
The Sentinel Admin Control Center (ACC) is the web-interface to the Sentinel run-time environment. It allows viewing/managing available keys, enabling and disabling them, controlling usage of remote keys etc.
To access the ACC, start any web browser and open the http://localhost:1947 page.
The Sentinel Admin Control Center is not able to display CHARON-AXP licenses - to view key contents, use the "hasp_srm_view" utility.
To access the Sentinel Admin Control Center start any web browser, open the http://localhost:1947 page. The web interface of the Sentinel Admin Control Center will appear.
The screenshot below gives an example:
This example demonstrates that 4 license keys are available:
A network key ("HASP-HL NetTime") on the host "XEON4WAYW7"
A network key installed locally
An HASP-HL installed locally
A network-wide software license on the host "RH64"
The Sentinel Admin Control Center reports that there is one opened session on key #4. The other keys are not being used at the moment.
Using the Sentinel Admin Control Center it is possible to check the available keys, verify the hosts on which they reside, verify the opened sessions, etc. For a more detailed description of the Sentinel Admin Control Center, please refer to its "Help" section.
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.
To disable access to remote keys, switch to the "Access to Remote License managers" tab, uncheck the "Allow Access to Remote Licenses" checkbox and press the "Submit" button to apply this setting:
To disable access to the locally installed license key from remote hosts, switch to the "Access from Remote Clients" tab, uncheck the "Allow Access from Remote Clients" checkbox and press the "Submit" button to apply this setting:
Accessing Sentinel Admin Control Center from remote hosts
By default, the Sentinel Admin Control Center forbids accessing its web interface from remote machines. To allow access, configure the ACC for remote management.
The first step is to edit the "hasplm.ini
" file:
|
# |
# ssh -L8080:CHARON_MACHINE:1947 root@CHARON_MACHINE |
License management utilities
Applying updates (".v2c" files) is typically done using the Sentinel Admin Control Center (see above) but alternatively it is also possible to use the specific "hasp_update" utility.
Removing CHARON-AXP software licenses
The following procedure must be applied to remove software license:
- Using your web browser, open the http://localhost:1947 page to access the "Sentinel HASP Admin Control Center" (ACC).
- In the "Sentinel HASP Admin Control Center" (ACC), locate the target "Sentinel SL AdminMode" license.
- Press the "Certificates" button at the right side of the SL description:
- Note the name of the corresponding certificate and path to the certificates base in the "Certificates" section.
- Remove the target certificate file from the specified directory, in most cases: "
/var/hasplm/installed/68704/
". - Reboot the CHARON host.
- Start the "Sentinel HASP Admin Control Center" (ACC) again to ensure that the SL has been removed.
License Deinstallation
To completely remove a CHARON-AXP license from a host, it is enough to remove the Sentinel run-time daemon (and the package "charon-license-<...>.rpm" containing the run-time customization) using the following command:
# rpm --nodeps -e aksusbd charon-license-<...> |
Special "backup" license keys
Backup keys are provided by STROMASYS along with standard license dongles. It is strongly recommended to order a backup key to recover immediately from damage or loss of the main license key. Backup keys use a counter (integer) value hardcoded inside the key. This integer value is a number of hours CHARON-AXP is allowed to run. Each time CHARON-AXP checks the license (every hour), the value is decreased (by 1 hour). Please note that backup keys have restricted functionality:
- CHARON run time is typically limited to 720 hours (30 days). This should be more than enough time to get a replacement key from STROMASYS.
- A backup license may be valid only until a certain date. Please check with STROMASYS management.
