One of our goals is to provide Linux administrators and users alike a place to quickly learn and develop their Linux skills. In keeping with this goal we are starting a Linux contest. Every week we will ask a Linux question, introduce a problem, or offer a challenge. Readers who want to participate must post their answer in the comments section corresponding with the question. At the end of four weeks the person who answers the most questions correctly will win a $25 Amazon Gift card.

So, in short, here is how the contest will work:

• One question will be posted every week on the Foogazi homepage (Subscribe to the RSS feed to receive updates whenever we post a new question)
  
• It is up to YOU to answer the question by posting a comment
• Comments will not be approved until two days after the question is posted to ensure everyone has a fair chance and to prevent copying.
• The best answer submitted to the comments after 2 days will be displayed in the main post and a winner will be declared
• The person who answers the question correctly and most accurately will win that weeks question challenge
• At the end of the four week challenge, the person who has the most questions answered correctly will win a $25 Amazon gift card
• In the event of a tie, the winner will be determined based on the time it took to post their answers, with the fastest person being declared the winner
• Speed is not as important as the quality of the answer!

The idea is to learn through challenges. So let’s get started!

The questions will start simple and increase in difficulty as the weeks go on.

The answer is: echo username >> /etc/ftpusers or "username"
