General description

CHARON-VAX products are product is protected by licenses, issued by STROMASYS for each customer individually. The CHARON-VAX license defines all the specifics of the particular CHARON-VAX distribution and its usage.

...

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

The The "hasp_srm_view" utility  utility displays the "active" license only. by default, but it is able to display all available licenses with "-all" parameter. It is also possible to check some specific license by its number using "-key" parameter.

The utility provides the license number and ID / IP address of the host where the active license is installed.

License installation

Installation of Regular and Network license keys

Installation of CHARON-VAX regular and network licenses consists of:

 

  1. Installation of the Sentinel run-time environment on the CHARON-VAX host (regular and network keys) or on the host that will distribute CHARON-VAX licenses over a local network segment (network key only). The Sentinel software ( the “aksusbd” RPM package) is installed automatically by CHARON-VAX for Linux.

  2. Physical connection of the HASP license dongle to the CHARON-VAX host or to the host distributing the CHARON-VAX 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-VAX installed), open the CHARON-VAX kit folder and proceed the following way:

# rpm --nodeps -ihv aksusbd-2.45-1.i386.rpm charon-hasplicense-4.67-1680217101.68704.el65el71.x86_64.rpm

Info

In case of network-wide license (red dongle) do the following:

  • On server side (where network license will reside): open port 1947 for both TCP and UDP
  • On clients side: open UDP ports 30000-65535
  • 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.

Info

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-VAX
  • Installation of a specific CHARON-VAX license Run-time provided by STROMASYS
Run-time replacement is a two step process:

  • Remove the current run-time (and the package "charon-hasplicense-<...>.rpm" containing the run-time customization) with the command

    # rpm --nodeps -e aksusbd charon-hasplicense-<...>

  • Change to the directory where the new run-time RPM resides (along with the corresponding "charon-hasplicense-<...>.rpm" customization package) and issue the command:

    # rpm --nodeps -ihv aksusbd<…>.rpm charon-hasplicense-<...>.rpm

Installation and update of CHARON-VAX Software License or HL/HASP dongle License

CHARON-VAX software licenses can be installed according to the following procedure:

  • Install CHARON-VAX together with Sentinel run-time (Sentinel run-time is an essential part of CHARON-VAX for Linux distribution)

  • Reboot host system

  • In case of Software License installation and if there are already installed network-wide SL's in local network disable access to network licenses in the following way:
    • Go to http://localhost:1947 to access the "Sentinel HASP Admin Control Center" (ACC).
    • Select "Configuration" option at the left panel, then "Access to Remote License Managers" tab.
    • Uncheck the highlighted options:
       
    • Press "Submit" button to apply settings
    • Select "Network" tab.
    • Switch "Network visibility" to "None":
       
    • Press "Submit" button to apply setting.
    • Do not forget to return these settings back after SL installation.
  • Connect HASP dongle to host system (in case of update of a license in a dongle)

  • Collect CHARON-VAX host fingerprint file (".c2v") - in case of first installation of Software License:

    # hasp_srm_view -fgp my_host.c2v

    or collect ".c2v" file in case if already installed Software License or 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-VAX 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" utility for applying ".v2c" file.

Info

Content of the installed software license is not shown by the Sentinel HASP Admin Control Center.To see it please run "hasp_srm_view" utility from 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 server side (where network license will reside): open port 1947 for both TCP and UDP
  • On clients side: open UDP ports 30000-65535
  • 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-VAX license management is performed by the Sentinel Admin Control Center and specific utilities. These are described in the sub-sections below.

Sentinel Admin Control Center

...

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.

To disable access to remote keys switch to the "Access to Remote License managers" tab and uncheck the "Allow Access to Remote Licenses" checkbox. Then press "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 and uncheck the "Allow Access from Remote Clients" checkbox. Then press "Submit" button to apply this setting:

Accessing Sentinel Admin Control Center from remote hosts

By default, Sentinel Admin Control Center forbids accessing its web interface from remote machines. To allow access, configure 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 Sentinel Admin Control Center run-time:
# /etc/init.d/aksusbd restart
If the CHARON-VAX 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 Linux documentation for details on how to configure the firewall.It is also possible to use SSH port forwarding with the following command (put the real CHARON-VAX host name instead of "CHARON_MACHINE"):
# ssh -L8080:CHARON_MACHINE:1947 root@CHARON_MACHINE
This will expose Sentinel Admin Control Center on port 8080 to any computer, and Sentinel Admin Control Center will believe commands are coming from the local host.

License management utilities

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

 

Info

Applying updates (".v2c" files) is typically done using Sentinel Admin Control Center (see above), but alternatively it is also possible to use a specific "hasp_update" utility for that.

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

Transferring and removing CHARON-VAX software licenses

Software Licenses Transfer 

Software Licenses (SL) can be transferred from one host to another using the "hasp_srm_view" utility and "Sentinel Admin Control Center" (ACC).

The following example demonstrates the transfer procedure.Let's suppose a Software License must be transferred from a host "SourceHost" to a host "RecipientHost":

  1. Collect the specific information about the "RecipientHost" to issue a transfer license. To do that run "hasp_srm_view" utility on the "RecipientHost" with the following parameters:

    $ hasp_srm_view -idf

    The file "recipient.id" will be created in the current directory.

  2. Copy the "recipient.id" file to the "SourceHost".

    Info
    "recipient.id" file is an ASCII file, so use "ascii" option in case of FTP transfer.

      

  3. On "SourceHost", open "Sentinel Admin Control Center" (ACC) (browse to http://localhost:1947). Note the number of the software license you are going to transfer.

  4. Run the "hasp_srm_view" utility in the following way to create a transfer license for the host "RecipientHost":

    $ hasp_srm_view -tfr <license number> recipient.id

    The "license number" is the value collected at step 3.Example of collecting a transfer license:

    $ hasp_srm_view -tfr 12345678 recipient.id

    The file "<license number>.v2c" will then be created in the current directory. In the example above the name of the transfer license will be "12345678.v2c"

  5. Copy the resulting "<license number>.v2c" file to the "RecipientHost".

    Info
    "<license number>.v2c" file is an ASCII file, so use "ascii" option in case of FTP transfer.
  6. On "RecipientHost", open "Sentinel Admin Control Center" (ACC) (browse to http://localhost:1947). Apply the "<license number>.v2c" file as described above

Software License Removal

It is also possible to remove Software License completely from a host, the license will then be dumped to a specific license file "*.v2c", so it can be re-applied if needed.

To remove the Software License completely from a host, do the following::
  1. Open "Sentinel Admin Control Center" (ACC) (browse to http://localhost:1947). Note the number of the software license you are going to remove.

  2. Run the "hasp_srm_view" utility in the following way to remove the license:

    $ hasp_srm_view -tfr <license number>

    The "license number" is the value collected at the step 1.Example:

    $ hasp_srm_view -tfr 12345678

    The "<license number>.v2c" file will then be created in the current directory. In the example above the name of the transfer license will be "12345678.v2c"

  3. It is always possible to re-apply the created ".v2c" file to restore the deleted software license.

Cloned Software License Removal

In certain situations Software License may become "Cloned" (disabled). In this case the following procedure must be applied to remove the cloned license:
 

  1. Go to http://localhost:1947 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: 
     
  4. Note the name of the correspondent certificate and path to the certificates base in the "Certificates" section.
  5. Remove the target certificate file from the specified directory (in most cases it is "/var/hasplm/installed/68704/").
  6. Reboot CHARON host.
  7. Start "Sentinel HASP Admin Control Center" (ACC) again to ensure that the SL has been removed.

License Deinstallation 

To completely remove a CHARON-VAX license from a host, it is enough to remove the Sentinel run-time daemon  (and the package "charon-hasplicense-<...>.rpm" containing the run-time customization) using the following command:

# rpm --nodeps -e aksusbd charon-hasplicense-<...>
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-VAX is allowed to run. Each time CHARON-VAX 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 from STROMASYS.
  • Backup license may be valid only until a certain date. Please check with STROMASYS management.
