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.
Steps
- On the offline system running Nessus (A), open a command prompt.
- Use the nessuscli fetch --challenge command specific to your operating system.
Platform Command Linux
# /opt/nessus/sbin/nessuscli fetch --challenge
FreeBSD
# /usr/local/nessus/sbin/nessuscli fetch --challenge
Mac OS X
# /Library/Nessus/run/sbin/nessuscli fetch --challenge
Windows
C:\Program Files\Tenable\Nessus>nessuscli.exe fetch --challenge
- Copy the alphanumeric challenge code.
Example Challenge Code:
aaaaaa11b2222cc33d44e5f6666a777b8cc99999 - Use the copied challenge code to Generate Your License.
