I'm currently a student in college studying computer networking. Out of all the things I'm studying, my strong suit seems to be Linux. With spring break coming up I would like to use the time to study for my Linux+ certification exam. I'm looking for suggestions for good sites, books, etc, from those who are Linux+ certified. Any suggestions are appreciated.
