How do I know if it has been restored?
Head to your Targets > Licenses and select 'Internal' from the 'Target type' dropdown:
If they have been restored, they'll look like this:
If they haven't been restored, they'll be greyed out and will look like this:
How do I manually restore my internal targets?
1. Unlink
⚠️ You must run the command as Admin
"C:\Program Files\Tenable\Nessus Agent\nessuscli.exe" agent unlink
* Assuming that the agent is installed in the default location
2. Relink
⚠️ You must run the command as Admin
Using the same target name you used initially to link the device, please run this command (replace [Prefix_TargetName] with your account Prefix and the Target Name - see below)
"C:\Program Files\Tenable\Nessus Agent\nessuscli" agent link --host="cloud.tenable.com" --port="443" --key=819652a91d674e8d5be08e21299f1a3c69bd9806c72e24bc05df6b32b8db7fe1 --name=[Prefix_TargetName]
3. Reboot
A simple reboot of the machine is all that's needed here.
4. Check that it worked
⚠️ You must run the command as Admin, in the folder where nessucli is installed (default location below):
cd "C:\Program Files\Tenable\Nessus Agent\"
The most common output (and next steps, if necessary) can be found here.
5. Kick off a scan
You can do this from several places in the portal, but the easiest is from the targets page. Simply select the target(s) and hit Scan:
Frequently Asked Questions
What does this mean for my licenses?
Once relinked and restored, the target will continue to use the same license, with the consumption period being reset by the next scan you run on it. No additional licenses are required.
What does this mean for my tags?
Once the target has been restored, the tags will be too.
What does this mean for my scheduled scans?
If all targets in the scheduled scan were deleted, you’ll need to recreate the scheduled scan
If some of the targets in the scheduled scans were deleted, you’ll need to re-add them to the schedule once relinked
If the scheduled scan was based on a tag, and only some of the targets were deleted, the tagged targets will be re-added to the scan once relinked.
What if I use group deployment?
If you used a tool to automate the rollout when you first deployed the agent, then it's probably best to automate the unlinking and relinking, too. Unfortunately, we can't offer any specific guidance or instructions on this, as the method and software used will be unique.
Where can I find my prefix?
Click Targets > Add target > Mass deployment:
Copy the Prefix (the one below has been redacted):
What is the target name?
The name you give to your device, so you can easily identify it in the portal.
