Enter your Challenge Code in the first field. Enter your Activation Code in the second field. Click "Submit." Step 3: Download the all-2.0.tar.gz Archive Once submitted, the portal will provide two critical items:
A download link: Click the link labeled "all-2.0.tar.gz" to download the latest plugin archive.
The nessus.license file: You must also download this file if this is your first time setting up the offline scanner.
💡 Pro Tip: Ensure you have enough disk space. This archive contains tens of thousands of plugins and can be quite large. Step 4: Installing the Plugins
After transferring the "all-2.0.tar.gz" file to your offline Nessus server via a secure USB drive or internal SFTP, you are ready to install. Stop the Nessus service: service nessusd stop
Run the update command: /opt/nessus/sbin/nessuscli update /path/to/all-2.0.tar.gz Restart the service: service nessusd start On Windows: Open PowerShell or Command Prompt as Administrator. Navigate to the Nessus install directory. Run: .\nessuscli.exe update "C:\path\to\all-2.0.tar.gz" Restart the Nessus service via services.msc. Troubleshooting Common Issues
Checksum Mismatch: If the installation fails, the file may have been corrupted during transfer. Always verify the MD5 or SHA256 checksum provided on the download page against your local file.
Expired License: The download link for "all-2.0.tar.gz" is tied to an active subscription. If your link does not work, check your Tenable Support Portal to ensure your license is current.
Processing Time: After running the update command, Nessus must "rebuild" the plugin database. This can take anywhere from 10 to 30 minutes depending on your server’s CPU and RAM. Do not interrupt the process. Final Thoughts
