Dealing with Frequently Changing Public IPs: No-IP DUC Script Setup

For situations where the public IP is constantly changing, install a background script using No-IP’s service:

1. Install No-IP DUC Client:

   cd /usr/local/src
   tar xzf noip-duc-linux.tar.gz
   cd noip-2.1.9-1
   sudo make
   sudo make install

2. Create and Configure the No-IP DUC Client:

   sudo /usr/local/bin/noip2 -C

• You will be prompted to enter your No-IP username, password, and hostnames you wish to update.

1. Run the No-IP DUC Client:

   sudo /usr/local/bin/noip2

4. Check the No-IP DUC Client Status:

   sudo /usr/local/bin/noip2 -S

5. Set Up Automatic Startup:

• Edit the crontab:
  sudo crontab -e
• Add the following line for auto-start:
  @reboot /usr/local/bin/noip2
