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
Run-time replacement is a two step process:

  • 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

  • In case of Software License installation and if there are already installed network-wide SL's on the local network, disable access to the network licenses in the following way:
    • Using your web browser, open the http://localhost:1947 page to access the "Sentinel HASP Admin Control Center" (ACC).
    • Select the "Configuration" option from the left panel then the "Access to Remote License Managers" tab.
    • Uncheck the highlighted options:
      Image Modified
    • Press the "Submit" button to apply settings
    • Select the "Network" tab.
    • Set the "Network visibility" to "None":
      Image Modified
    • Press the "Submit" button to apply the settings.
    • Do not forget to return these settings back after the SL installation.
  • 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, "Browse" for the "*.v2c" file and then "Apply File".

  • Ensure that the license appears in the “Sentinel Keys” menu.


Info

Alternatively it is also possible to use "hasp_update" command line utility for applying the ".v2c" file.


Info

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.


Info

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

...

The screenshot below gives an example:

Image RemovedImage Added

This example demonstrates that 4 license keys are available:

  1. A network key ("HASP-HL NetTime") on the host "XEON4WAYW7"

  2. A network key installed locally

  3. An HASP-HL installed locally

  4. 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:

# vi /etc/hasplm/hasplm.ini


Allow remote access by changing the "ACCremote" parameter from "0" to "1" then restart the Sentinel Admin Control Center run-time:
# systemctl restart aksusbd
If the CHARON-AXP host firewall is blocking remote access to the Sentinel Admin Control Center, please configure the firewall to open the port 1947 (TCP protocol). Refer to the Linux documentation for details on how to configure the firewall. It is also possible to use SSH port forwarding with the following command (replace "CHARON_MACHINE" by the real CHARON-VAX host name):
# ssh -L8080:CHARON_MACHINE:1947 root@CHARON_MACHINE
This will expose the Sentinel Admin Control Center on port 8080 to any computer, and it will believe commands are coming from the local host.

License management utilities

CHARON-AXP for Linux provides a specific utility for license management - "hasp_srm_view". This utility is used to display the license(-s) content, to collect the key(s) status information and host fingerprint (C2V) files.


Info

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.

Please refer to the Utilities section of this Guide for more details.

Removing CHARON-AXP software licenses

The following procedure must be applied to remove software license:
 

  1. Using your web browser, open the http://localhost:1947 page to access the "Sentinel HASP Admin Control Center" (ACC).
  2. In the "Sentinel HASP Admin Control Center" (ACC), locate the target "Sentinel SL AdminMode" license.
  3. Press the "Certificates" button at the right side of the SL description: 
    Image Modified 
  4. Note the name of the corresponding certificate and path to the certificates base in the "Certificates" section.
  5. Remove the target certificate file from the specified directory, in most cases: "/var/hasplm/installed/68704/".
  6. Reboot the CHARON host.
  7. 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-<...>
Then just physically disconnect the license key (in the case of protection by dongles).

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.
