Reset the license for Ensim Pro Control Panel Linux

Ensim Pro Control Panel license is tied to a MAC-address. Therefore, when you change your network card, Ensim does not recognize the license as valid anymore.

Rename /etc/appliance/.license/.LIC_file and /etc/appliance/.license/.MLK_file so that the license would be treated as a new one by Ensim

Once this is done, we need to contact support to reset the license.

Upgrading License Key for Your Plesk Panel

Parallels Plesk Panel comes with a trial license key, which is automatically installed to the control panel. This license key allows you to create one user account, host one Web site and one mail box. Therefore, to fully use the Parallels Plesk Panel as you need, you should obtain a license key from Parallels or one of its resellers and install it to the control panel.

Parallels Plesk Panel will attempt to connect over TCP/IP to the licensing server through port 5224. Please make sure that this is not blocked by a firewall. The update process runs automatically and the Parallels Plesk Panel administrator does not need to do anything unless there is a problem. Should the Parallels Plesk Panel key expire, check your firewall and then go to Home > License Management (in the Help & Support group) and click Retrieve Keys. If the key cannot be updated, contact your reseller or Parallels (if you purchased the license key directly from Parallels).

You can test the connection to the licensing server anytime by going to Home > License Management (in the Help & Support group) and clicking Retrieve Keys.

1. Check whether the license is expired.

3. In that case, check whether the firewall is blocking connections to the licensing server.

Verify that port 2089 TCP outgoing traffic is allowed in the firewall rules.

4. If you’re not sure that your firewall is properly configured, then the best thing to do is temporarily flush your firewall rules. Before flushing the firewall rules, you need to save the firewall rules enabled in the server.

After that you can flush your firewall rules using the command
