The book is hot and ready containing a lot of ( I'd like to think ) useful information about configuring different type of servers based on Red Hat® Enterprise Linux® 5.
For each chapter I've tried to provide exercises as closer as possible to real life that might help any system administrator to figure out solutions in case problems may occur. Pretty fair, right?
As an addition to the Observation in Chapter 3 page 52 referring to the use of the cat command calling the /dev/urandom device for generating a random set of passwords, allow me to launch this challenge:
How would you generate a set of passwords containing 9 random characters when you want to use all numbers, symbols, and letters of your native language (of course, considering that your keyboard is set appropriately for your native language).
cat /dev/urandom | tr -cd " ? " | fold -w ? | head
Replace the question marks with the right expressions and ... check if it works!
