Simply issue this final command to launch the client in the background: Now that the client is installed and configured, you just need to launch it. If answered incorrectly this could affect hostnames in your account that are pointing at other locations. Be careful, one of the questions is “Do you wish to update ALL hosts”. You will then be prompted for your username and password for No-IP, as well as which hostnames you wish to update.

Note: If you do not have privileges on the machine you are on, you may add the “sudo” command in front of steps (5 and 6). You can become the root user from the command line by entering “sudo su -” followed by the root password on your machine. The below commands should be executed from a terminal window (command prompt) after logging in as the “root” user. You can still set up connections to multiple devices but make sure that each specific hostname is not updated by more than one update client. An update client is a device with DDNS settings configured and enabled. If you have multiple update clients updating the same hostname the service will not work properly.

Note: You do not need to use the DUC if you’ve already configured DDNS in a router, DVR, camera, or other device. If you have issues installing the Linux DUC below, installing the newer version v3.x will typically solve these issues and offer more stability. We recommend most users utilize our new Linux DUC available here, which is more modern and stable. If you are using Ubuntu Linux, please click here. This guide will walk you through the installation and setup of the Dynamic Update Client (DUC) on a computer running Linux.
