Activating a license with a key


A license is activated with a key if the public IP address is not assigned to the server network interface. Use it if your server runs behind the NAT. 

If the license IP address doesn't match the server public IP address, complete the following steps:

  • activate your license with a key;
  • change the license IP address. We recommend that you use this method as it allows for correct automatic activation of your license. Learn more in the article License IP address

Execute the command:

/usr/local/mgr5/sbin/licctl fetch mgrName key

mgrName is the short name of a control panel.

The activation key can be used only once. Generate a new key if you want to activate the license again. Generate a new key in your Client area.
