Hi all,
I have noticed lately that a lot of job openings for my position (devops) put a strong emphasis on having TCP/IP knowledge which is something I know virtually nothing about. It was a topic that glossed over in school and I have yet to encounter anything involving networking concepts in my big boy job. I am trying to learn about this stuff on my own because if I want to advance in this career at all it looks like I'm going to need to have a pretty strong understanding of network concepts. Does anyone know of any good (preferably free) material/exercises involving this concept? Thanks!
