iLok Server and Floating Licenses

iLok Server is an extra feature of iLok License Manager that allows you to use a computer to serve sharable licenses across your network so that other users (clients) can also authorize the protected software to run. For each computer that will be used as a license server, you will need one iLok Server license.

In order to set up a license server and share licenses, you will need the following:

A networked computer to act as the license server.
A 2nd-generation or later iLok USB with a license for the product iLok Server on it.
One or more sharable licenses to share on your network. Sharable licenses are different from regular licenses in that they have a number of seats assigned to them. The number of seats corresponds to the number of other computers that can concurrently use the license over the network. Sharable licenses that are shared across a local area network (LAN) are also called sharable licenses.

iLok License Manager must be configured for automatic discovery of network servers OR a config file needs to be generated by the iLok manager running the license server, and that config file copied to the local machine. In order for automatic discovery to take place, the Bonjour service needs to be running and set to automatic startup. Check that you have the server set for automatic discovery on the systems that won’t launch.

The dialog is accessed via the file>preferences menu in the iLok manager.
