Display License Content with Linux-Specific Tools

The license content on Linux systems can be displayed using the hasp_srm_view command. 

If the command is not in your PATH variable, the full path has to be specified:

• Path to image for Charon-AXP/VAX and Charon-PAR 1.10 and later: /opt/charon/bin/hasp_srm_view
• Path to image for Charon-SSP: /opt/charon-agent/ssp-agent/utils/license/hasp_srm_view

Example of a hasp_srm_view command that will show all licenses visible on the system:

$ /opt/charon/bin/hasp_srm_view -all



A complete list of the parameters of the hasp_srm_view command is shown in hasp_srm_view.

The commands described in this section also work on Charon-SSP. However, Charon-SSP has its own GUI, the Charon-Manager, which also includes a license viewer. Please refer to the section License Management with Charon-SSP Manager for more information.

Displaying the license content when connected via the network:

Local hardware licenses can only be displayed from a local connection to the system, for example via the console. If you are connected via a remote connection, for example via ssh, the hasp_srm_view command will return an error. Network licenses (network-enabled dongles and software licenses) do not have this problem.

Workaround when logged in via a remote connection:

When connected to the system via a remote connection, the command to display a local hardware license will return an error. As a workaround, you can display the license contents with the following command (adapt the path of the command if your installation location is different):
$ ssh localhost /opt/charon/bin/hasp_srm_view

Please note: starting with Charon-AXP/VAX 4.9 and Charon-PAR 1.10, the hasp_srm_view utility on Linux does not follow the settings in the Sentinel ACC with respect to querying remote license servers and network visibility. The utility performs a broadcast search for network licenses even if this has been disabled in the Sentinel ACC. If this behavior has to be prevented for specific reasons, the network access of the system must be temporarily restricted or disabled, for example by blocking the relevant traffic with a firewall. Alternatively, access to the network license at the license server side can be blocked. Note that such methods can negatively impact other functions of the system or, in case of blocking access to a network license on the server, even the functions on other client host systems.

Please note: in rare cases, you may have received an empty dongle without a license section. The hasp_srm_view command will show that no license information was detected. In such cases, please refer to the steps on how to request a license update for a USB dongle.

Starting with license driver versions >= 7.60, for example, in Charon-AXP/VAX version 4.9 and Charon-PAR version 1.11, there are some small changes in the output of hasp_srm_view. The parameters are described in the License Content section of the Licensing Handbook. The following sample shows the most important changes (in blue):
