5. License system concepts


This chapter introduces the basic concepts of the MOSEK license system.

5.1. How the license system works

MOSEK is a licensed software product which means you that must have a valid license in order to use MOSEK. A license is a file which specifies:

The license is managed by the FLEXlm license manager supplied with MOSEK. Two types of licenses exist for MOSEK:

All commercial MOSEK licenses are floating licenses.

5.2. Sharing a single license between multiple non-networked computers

A license file should be tied to a dongle in order to share a single license among multiple computers not connected to a network . Please see Section 5.3.1 for further details. Most MOSEK users do not use a dongle and for most set-ups it is not advisable as it complicates the installation. A better setup for using MOSEK on computers not connected to the network is to install the license server with a single license on each non-networked machine. This will allow MOSEK to run on each machine even when disconnected from the network.

5.3. The host ID

A floating license is tied to a particular computer acting as a license server. The license server is identified using a unique ID known as the host ID. Usually the host ID is identical to the MAC address of a network card. Therefore, the computer needs to be equipped with a network card. However, an actual network connection is not needed as MOSEK requires only a number coded in the network card.

5.3.1. A dongle host ID

Alternatively a license can be tied to an ID in a dongle which is a small piece of hardware that is attached to a USB port. The advantage of using a dongle is that the dongle can be moved to another computer. A license can e.g be used at the office and at home without the two locations being connected by a network. Please Note that the license server software must be installed on each computer the dongle is used on. For information on how to obtain the host ID see Chapter 7.

5.4. Further information about FLEXlm

Further information about the FLEXlm license system is available in the Flexlm end user manual available on the MOSEK website.
