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

  1. On the offline system running Nessus (A), open a command prompt.
  2. Use the nessuscli fetch --challenge command specific to your operating system.
    PlatformCommand

    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

  3. Copy the alphanumeric challenge code.
    Example Challenge Code:
    aaaaaa11b2222cc33d44e5f6666a777b8cc99999
  4. Use the copied challenge code to Generate Your License.
