In this section I cover a few of the most common cases we handle. Sometimes folks have situations that require manual configuration. This failure often affects VPN clients as well, since broadcast packets typically aren’t rebroadcast on the other side of a routed interface.įirewalls (hardware, software, or virtual hardware) can also block License Service traffic if configured to disallow traffic on TCP and UDP port 1947. Even if you don’t use a firewall to block network communications between two routed network subnets, most routers automatically drop all broadcasts (the UDP port 1947 broadcast discovery does not reach in between LAN segments). For instance, larger networks typically have a separate segment for server systems. The most common reason for failing to discover a license server is the discovery process’ inability to find an available License Manager with an attached Sentinel Hardware License Key.

The Sentinel LDK documentation describes this further. Broadcast discovery uses UDP port 1947 once a remote License Manager is discovered, further network communication moves to TCP port 1947.

Out-of-the-box configuration of the License Manager allows the service to listen for license requests and issue broadcast searches for available licenses. If that doesn't describe you, feel free to skip down to the next section. This section mainly applies to systems/network administrators or other curious souls who want to understand how the Sentinel LDK License Manager communicates with other systems. It is red and looks very similar to a USB thumb drive.ĭescribe the magic and common reasons for it to fail The physical key attached to the computer that contains CEI licenses.

The Sentinel Driver & License service is automatically installed with our software and sometimes is already on the computer. Install the program, plug in the key, and it just works. Since we have implemented Sentinel (formerly HASP) hardware licensing, its usage and setup have generally been “magical” for the user.
