To rename a target you will need to unlink the agent and then relink with the correct hostname.
Unlink command
Windows (Run as Administrator)
"C:\Program Files\Tenable\Nessus Agent\nessuscli.exe" agent unlink
Linux
sudo /opt/nessus_agent/sbin/nessuscli agent unlink
MacOS
sudo /Library/NessusAgent/run/sbin/nessuscli agent unlink
Relink command:
Windows: (Run as Administrator)
"C:\Program Files\Tenable\Nessus Agent\nessuscli" agent link --host="cloud.tenable.com" --port="443" --key=[KEY] --name=[Prefix_DeviceName]
Linux
/opt/nessus_agent/sbin/nessuscli agent link --host="cloud.tenable.com" --port="443" --key=[KEY] --name=[Prefix_DeviceName]
MacOS
/Library/NessusAgent/run/sbin/nessuscli agent link --host="cloud.tenable.com" --port="443" --key=[KEY] --name=[Prefix_DeviceName]
Once you've done that, it should take a couple of minutes for the internal system to show up.
