Starting with VE license server version 1.1.13, the previous information-only web interface has been changed to a management interface. It provides the following functions:

...

Prerequisites:

• The TCP port used by remote systems to web-based management interface must be permitted on the license server, and by any intermediate firewall.
  Default: TCP/8084; an alternative port can be configured in /opt/license-server/config.ini.
• TCP port 80 must be available to the license server to redirect HTTP requests to HTTPS. For remote connections, the port must also be permitted through intermediate firewalls. Starting with version 1.1.25, redirection (and thereby use of TCP port 80) can be enabled or disabled in /opt/license-server/config.ini.
• Important: at the time of writing, the web-server component of the license server applications will not start if a port required by the web server is already used by another application. This will also prevent the licensing component from starting.

Accessing the Management GUI and Logging in

The web-based management GUI is provided by the license server on TCP port 8084 by default (the port can be changed in /opt/license-server/config.ini; see also Additional Configuration Options - the config.ini File).

Use the following URL in any web browser to access the management GUI:
https://<host>:<port>/ wherewhere

• host is the name or address of the VE license server, and
• port is the TCP port (8084 by default).

Use localhost as the hostname for accessing the GUI of a license server running on the local system. Example: https://localhost:8084. Using just http://<license-server-ip> will redirect to the configured HTTPS port.

Please note: any intermediate firewall must allow the TCP port ports used for the management GUI.

...

After logging in, you will be presented with a list of menu options on the left pane of the screen and the content of the selected option on the right hand. Please change the default password immediately.

Certificate Warning when Connecting to the Management GUI

When connecting to the VE license server web-based management GUI for the first time, the web browser will issue a NET::ERR_CERT_AUTHORITY_INVALID warning and inform the user that the connection is not private. This is due to the fact that Stromasys, when creating the installation kit, cannot foresee the actual customer environment. Thus, the SSL certificate included with the license server kit includes a dummy hostname that does not match the real hostname of the customer license server system, and it also contains Stromasys as the certificate authority which is unknown to web-browsers by default.

It is possible to override the warning and connect to the page. Otherwise, users must

• either obtain a certificate for the host from one of the commercial certification authorities, or
• they must create their own self-signed certificate and add it to the web browser.

The new certificates replace the certificates in /opt/license-server/certs (move the old certificates to a save place).

Steps to create a self-signed certificate:
