Using the License Key

This section describes how to use license keys for Flussonic Media Server and what actions are available without a license key.

Flussonic Media Server license key

The license key is stored in the file /etc/flussonic/license.txt.

On the first run of a newly installed Flussonic, you will be asked to enter the license key that you have received. Later, there are two ways to edit the key: you can edit it in /etc/flussonic/license.txt or in the Flussonic's web UI in the Config section.

The key looks like l4|WXHMkfXhFHeNmvDz-M_tb4|r6BzpmVPpjgKpn9IunpFp5lLbCZOp3

The server must have access to the Internet via HTTP and HTTPS to be able to validate the license key.


Flussonic licensing server does not make any requests to your server, so you don't have to add it into the white list when limiting access to your server. For correct Flussonic licensing, you should allow OUTBOUND (stateful) connections for ports 80 and 443 on your server.

Binding the key

Flussonic requires regular connection with the key server for binding the license key.

Migrating the license key to another server

Flussonic validates the license online so it is very easy to move your license to another server.

Just shut down Flussonic on the first server and launch it on the new one.

Flussonic's web interface without a license key

If the license key is invalid or missing, the Flussonic web interface opens in a truncated mode and shows the "no license" page. On this page you can enter the license key or upload the activation file for your USB key.

Without a license key, the only sections available are Config > Settings and Support. For Flussonic Coder, in addition to these sections, the Chassis section is available.
