Appendix E. License key installation
GRMON is licensed using a Sentinel LDK USB hardware key and has support for node-locked and floating license
keys. The type of key can be identified by the color of the USB dongle. The node-locked keys are purple and the
floating license keys are red.
1. Node-locked keys (purple USB key)
For node-locked keys, the Sentinel LDK Run-time for the key must be installed before the key can be used (see
below).
2. Floating keys (red USB key)
In the case of floating keys, the Sentinel LDK Run-time must be installed on the server and the client computer
(see below).
Sentinel LDK communicates via TCP and UDP on socket 1947. This socket is IANA-registered exclusively for
this purpose. By default the client will find the server by issuing a UDP broadcast to local subnets on port 1947.
If broadcasting is not working or unwanted, then advanced network settings can be setup via the Sentinel Admin
Control Center. The Sentinel Admin Control Center is accessed by opening the url localhost:1947 in an webbrows-
er. The network settings are reached by selecting "Configuration" in the menu and then selecting the "Access
to Remote License Managers" tab. Detailed information on how to setup the network settings can be found by
selecting "Help" in the menu.
3. Sentinel LDK Runtime
The latest runtime can be found at the GRMON download page. Included in the downloaded Sentinel LDK runtime
archive is a README file which contains detailed installation instructions. However, ignore all instructions about
installing
haspvlib_<vendorID>.so
and/or
haspvlib_x86_64_<vendorID>.so
.
Administrator privileges are required on Windows. On Linux it is required that the runtime is installed as root user.
