For each agent that you install, you must have a license available, or the machine(s) won't show up on your targets page. (eg. If you're installing the agent onto 10 machines, you must have 10 licenses available.)
For group deployment, have a read of this article.
Please note that each machine must have a unique device name. If you use the same name as an existing internal target, it won't link.
Step 1: Download the agent installer (but don't launch it)
1. Head to the targets page > select Add target > Internal targets
2. Choose between a Single agent deployment (providing instructions and a link to download the agent for the machine) or Mass deployment (providing the parameters you need for your installation script).
If choosing Single Agent deployment:
3. Enter the details for the machine you wish to scan:
👉 Operating System
👉 Operating System version
👉 Your device name (this must be unique and contain only letters, numbers, or hyphens)
👉 Tag(s) (optional)
➡️ Hit 'Download agent'
Note: The version of Linux you're using could influence the directory where nessus downloads to
Step 2: Install the agent + link the agent
👉 Open terminal
👉 Run the first command (to install the agent)
👉 Run the second command (to link the agent)
You should then see your target appear in the portal:
Step 3: Reboot the machine
👉 Reboot the machine
👉 Confirm it is online and able to reach
cloud.tenable.com.
Note that for a scan to run on this target, the machine will need to be online and able to reach cloud.tenable.com for the target to show as responsive.
Possible error messages
error: Failed dependencies:
This means that the installation has failed because some dependencies need to be installed first – they should be listed under this message. If you could install them first, and then try the installation again, it should work.
