License Activation

This guide explains how to activate your software license online using CodeMeter.

For Headless Ubuntu Systems

If your Ubuntu server has a graphical interface and browser, you can skip directly to the Activate License section below. The setup instructions are only needed for headless systems accessed via SSH from a Mac.

Prerequisites

  • Internet access
  • Administrative privileges on Ubuntu Server
  • Your software license key
  • Mac with XQuartz installed (only for headless Ubuntu systems)

For Headless Systems (Optional)

Note

Skip this entire section if your Ubuntu system already has a browser installed. This section guides you through setting up X11 forwarding to run a browser on Ubuntu and display it on your Mac.

Step 1: Install Chromium on Ubuntu

Run the following commands to install Chromium:

sudo snap install chromium
export XAUTHORITY=$HOME/.Xauthority

Step 2: Configure XQuartz on Mac

1. Enable network connections

  • Open XQuartz → Settings... → Security
  • Check "Allow connections from network clients"
  • Close Settings

Allow connections

2. Set DISPLAY variable

export DISPLAY=:0
echo $DISPLAY

3. Enable local X connection

/opt/X11/bin/xhost + 127.0.0.1

4. Connect to Ubuntu with X11 forwarding

ssh -Y -C user@remote.server
  • -Y = trusted X11 forwarding
  • -C = optional compression

Step 3: Launch Browser on Ubuntu

1. Verify DISPLAY is set

echo $DISPLAY

You should see something like localhost:10.0

2. Test XQuartz connection

xclock

A small clock should appear on your Mac, confirming X11 forwarding works.
