Hello everyone,
I am currently beginning to look for a job after my contract with the Air Force is up. I have put my resume on Monster and been receiving at least an email/call a day about a job. What I have noticed with some of them is that they require knowledge in Linux/Unix environment OS. Most of these jobs have been network engineer, however I have also been offered network administrator and security analyst. What would be a good class that primarily entails UNIX OS that could help me in this grand endeavor? Any help would be highly appreciated.
