Hello, I met a really great guy through getafreelancer.com who helped me to set up few things on my linux dedicated server (he set up live TV streaming) and also fix some security holes. He is incredibly professional, very trustworthy and his knowledge of linux/unix based systems is just incredible. Every challenge is an easy task for him. He has a lot of experience, he also used to help police in finding who hacked some servers and so on. He is currently without a job, because his old company was only using him for little money. He works either on per hour basis (very cheap rate) or you pay him something per month and he is steadily available and keeps an eye on your servers as if they are his own. I can highly recommend him, so if anyone needs linux/unix sys admin PM me, I'll give you contact.
