    • How to use the JLinkRemoteServer CL version

      I'm using successfully the JLinkRemoteServer GUI with the following configuration:(see attached file)


      I want my computer to launch Jlink server at startup.
      Therefore I want to use the headless version: JLinkRemoteServerCl.exe, but I'm not able to connect succesfully.

      My guess is that I'm not using the correct flag, but the ? help is not very detailed.
      How do I reproduce my config using command line flags?
      Regards,
      Gabriel

    • Hello,

      It seems like you are using just the default settings of the remote server, so no additional command line options should be needed.

      Could you please provide one log of the failing scenario and one of the successful one?

      The log can be enabled with "-Log <LogFilePath>".

      Best regards,
      Simon

    • Hello,

      The logs appear to be fine.

      It's possible that the port (19021) is being blocked by your firewall, or that the RemoteServerCL application does not have the necessary permissions to access your local network.

      Best regards,
      Simon

    • Hi Simon,


      Thanks for checking the log.

      Can you elaborate on the permission/firewall issues?
      Don't you think it would be surprising that RemoteServerCL would be blocked, but RemoteServer would work fine?

      Regards,
      Gabriel
