After being a system admin for 4 months, i think that this is my dream job but the pay is still not enough for me. I've learnt so many things about Linux and how to maintain them (I have 3 servers that i have to monitor). May things on my mind ranging from backup (the hardest if u want to transfer accounts from one server to another server.), tcp/ip, network design, firewall (this is fun!), routing config and etc.
