Generate Challenge Code
Before performing offline update operations, you may need to generate a unique identifier on the Nessus server. This identifier is called a challenge code.
Whereas an activation code is used when performing Nessus operations when connected to the internet, a license is used when performing offline operations; the generated challenge code enables you to view and use your license for offline operations.
- On the offline system running Nessus (A), open a command prompt.
- Use the nessuscli fetch --challenge command specific to your operating system.
# /opt/nessus/sbin/nessuscli fetch --challenge
# /usr/local/nessus/sbin/nessuscli fetch --challenge
Mac OS X
# /Library/Nessus/run/sbin/nessuscli fetch --challenge
C:\Program Files\Tenable\Nessus>nessuscli.exe fetch --challenge
- Copy the alphanumeric challenge code.
Example Challenge Code:
- Use the copied challenge code to Generate Your License.
