To ensure a sensor is fully up-to-date with scripts pertinent to Pwnie Express as well as packages available from the Kali repository, please perform the following steps:

  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 px-connection-dr and press Enter to verify the sensor has connectivity to the update servers.


    When using the px-connection-dr command/script the tests performed include checking DNS resolution, checking TCP connectivity to ports 80, 443 and 873 and ensuring SSL Filtering is *not* being performed upon any of the connections. It is therefore required for *all* tests to either reflect SUCCESS and/or VALID. If any of the tests should reflect FAILURE and/or INVALID, then the issue involving connectivity needs to be resolved before continuing.

  4. Assuming all tests passed, type rm /opt/pwnix/chef/latest-version-id and press Enter to remove a file indicative of the last update performed.
  5. 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.
  6. Now, type px-system-update and allow the sensor to update itself.


    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.

  7. After returned to the # prompt and to be sure the sensor is fully up-to-date, please repeat steps five and six. This second update will likely take much less time, often less than five minutes.
  8. When finished and returned to the # prompt, you should be all set to continue with the use of the sensor.


    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.
