We are BaseOS QE team, which takes care of RHEL's (Red Hat Enterprise Linux) quality as it's main responsibility. So, we test RHEL, but that doesn't mean we just randomly push buttons in the GUI :) We use various tools for testing (Bash, Python and testing frameworks written in those languages, automation, static code analyzers, etc.), we work in terminal most of the time, automate a lot and have to deal with a huge range of technology.
In this game you have a chance to try some of those. You'll look for security exploits, write tests in Python testing framework - Behave, and look for errors in an RPM package with internal testing framework BeakerLib.
The game is composed of 3 levels. In each level you have to get a secret code that should match pattern OH19_[A-Z1-9] (aka it is prefixed by OH19_). As soon as you get the secret code, level is considered done and you may get a gift :)
In your home directory /home/oh you will find level1/, level2/ and level3/ directories:
$ cd /home/oh
$ ll
drwxrwxr-x. 2 oh oh 4.0K Apr 17 08:29 level1
drwxrwxr-x. 4 oh oh 4.0K Apr 17 08:29 level2
drwxrwxr-x. 2 oh oh 4.0K Apr 17 08:29 task-behave
Each of these directories contains a task (level), including README file. It's recomended to start with reading this file.
