This article describes how to manually install the internal vulnerability scanning agent on a Linux device (we also have installation guides for Windows and macOS):

Step 1: Download the agent installer (but don't launch the installer).

  • Select the right installer package for your flavour of Linux and download it.

Step 2: Install the agent

Fedora, Red Hat, CentOS, and Oracle Linux:

rpm -ivh [NessusAgent package].rpm

Ubuntu, Debian:

dpkg -i [NessusAgent package].deb

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).

Once you have the above information ready, open a Terminal window and run the following command:

/opt/nessus_agent/sbin/nessuscli agent link --name=DeviceName --key=Key --cloud

Note: The location of nessuscli might vary depending on your version of Linux
