This article describes how to manually install the agent on a Linux device. If you wish to individually install the agent on your devices, you can use the installation wizard inside the platform.
🚨 IMPORTANT 🚨
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.
👉 If you're installing the agent on 10 machines, you must have 10 licenses available.
Step 1: Download the agent installer
Head to the Nessus agent download page:
https://www.tenable.com/downloads/nessus-agents
Search for the relevant .dmg installer file (i.e. NessusAgent-X.X.X.dmg) and download it.
Step 2: Install the agent
Double-click on the .dmg file and then double-click the "Install Nessus Agent.pkg" installer.
Step 3: Configure and link the agent
To configure: Open the Targets page > Add Targets > Internal targets
Click 'View configuration keys'
Copy the 'Prefix'
Your DeviceName is comprised of your Prefix and your TargetName
(what you'd like the target to be named in the portal).
👇
DeviceName = Prefix_TargetName (eg. DQEGBQUAAAc_paul-laptop).
To link:
Open the Terminal app
Run the following command, making sure to update:
DeviceName (see above)
Key (see above)
sudo /Library/NessusAgent/run/sbin/nessuscli agent link --name=[DeviceName] --cloud --key=[Key]Note: Internal vulnerability scanning is only available to Pro and Vanguard customers.
