For each agent that you install, you must have a license available; if you don't, 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, 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. . 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)
👉 (optional) Add any tag(s)
➡️ Hit 'Download agent'
Note: The version of Linux you're using could influence 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)
Step 3: Reboot the machine
You should see something like this pop up:
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, then try the installation again, it should work.
Note: Internal vulnerability scanning is available to users with a Pro, Premium or Vanguard plan.
