Troubles… and likely answers. One or more of the following situations can prevent Syndeia users, in their desktop applications, from getting a license seat from the Intercax Reprise License Server.

  • My Cameo or Rhapsody users cannot obtain a Syndeia License when the modeling tool starts.

  • My Intercax Reprise License Manager isn’t running

    • The server for that license manager is offline

      • Work with the greater IT team to get the license server’s host (or container node) back online

    • The Intercax Reprise License Manager isn’t installed

    • The OS is failing to start the service

      • Work with your Linux or Windows Administrator SME to determine why an installed system service is failing to start.

  • Everything seems to be operational but the clients are told that no license is available

    • The license server has an active (in effect) license for a different version

      • Check that the specific user is running the right version of the Syndeia Plugin that the License Server has an active license for. Licenses are specific to versions of Syndeia.

      • Syndeia Floating Licenses

  • Everything seems proper but the clients can’t reach the server

    • The network between the client workstations and the license server is blocking or altering traffic

      • Use routine network health tools to determine if hosts are reachable, ports are open, HTTPS sessions are established, traffic can flow both ways

      • Work with your Networking SME to determine why routine clients like curl, ping, netcat, telnet, and openssl client cannot communicate bidirectionally between the troublesome workstation and the license server host

  • Network IT Staff

    • Expand the following “packet trace” to see the network traffic between a Syndeia Plugin client and an Intercax Reprise License Server. This reveals all the ports and protocols used by both the client and the server to request, receive, and return a license. If any ports are blocked on either side, your users won’t be granted a license.

      • Notice that the client workstation needs to be able to open a new dynamic ephemeral port in the 40000-70000 range that is allowed to originate outbound traffic to both 5053 and 5055 on the server

      • Notice that the server has to be able to receive incoming traffic on both 5053 and 5055 (as well as 5054 for the License Admin service)

      • Notice that the server has to be able to reply through ports 5053 and 5055 to those high-range ephemeral ports on the client

      • Notice that the client does not use one and only one dynamic outbound port, it uses several and the actual ports will vary
