Ok guys am going to throw this question on the pipe so i can have good feedback. I have been working in windows environments for close to 5 years and I have achieved a good experience and goals on the networking and systems administration. But form day one i have a special interest in Unix systems but i never had the opportunity to work in a place that have that kind of platforms an I felt like incomplete in that area, but then Linux appears and the whole game changed and i started like 1 year ago to experiment with different versions of Linux like Red Hat, Free BSD, Mandrake, ect.
Now I am experimenting with oracle 9i database and application server in Red Hat 7.3 (witch is really amazing) and I think I really want to get the Linux area more seriously and get certified on Linux. So this is the question its worth it get certified on Red Hat or other Linux certs?? Or what other things I can do.
