How to re-apply updates to a sensor

Last Updated: Oct 11, 2019 12:15PM EDT
1. Use SSH and login to the sensor with the pwnie user account.
2. Type sudo su and press Enter, then re-type the password to become superuser.
3. Next, type rm /opt/pwnix/chef/latest-version-id and press Enter to remove a file indicative of the last update performed.
4. Next, type rm /opt/pwnix/chef/installed-version-id and press Enter to allow the sensor to attempt updates again within 24 hours of the last update. Note this file may not exist.
5. Now, type px-system-update and allow the sensor to update itself.

IMPORTANT: Do not interfere with the sensor until it is finished and you are returned to the # prompt. Please know it may take the sensor as long as 45 minutes to update.
6. After returned to the # prompt and to be sure the sensor is fully up-to-date, please repeat steps four and five. This second update will likely take much less time, often less than five minutes.
7. When finished and returned to the # prompt, you should be all set to continue with the use of the sensor.

HINT: To validate a sensor is up-to-date, type cat /etc/motd and press Enter, then review the banner displayed specifically looking at the Pwnix Release. Next, review the "History of Pwnix Releases" article available at
