Issue Details

I want to connect 2 host computers to the same Linux RT target via NI VeriStand. Through this way, two users can control the same target simultaneously. I deploy the VeriStand SDF successfully from host computer 1. When I try to connect to the Gateway from host computer 2, it fails with error.

Solution

Starting from VeriStand 2024, a security feature is added to authenticate connections. VeriStand 2023 and 2021 versions are also patched. There are 2 ways to resolve this issue.

  1. Open VeriStand. Navigate to File ->Preferences->Security. By default, Gateway Security type is set to WindowsIdentity. Change the Security type to None to disable the Gateway security.

  1. If you only allow the trusted computers connecting to the gateway, keep the default Security type setting and add the trusted users in Authorized users. With this way, the trusted computers should be in the same domain.

       The trusted computer names can be obtained by entering whoami in the Command Prompt window.

Additional Information

If the multiple host computers are not in the same domain, you have to disable the Gateway security on the host that you run the VeriStand Gateway.
