how to tell when you have a hacker?

[Mike]

My password is more complex than a name. (it isn't even a word). But please do 
share with me how to check if ssh is open, what port it is on, and how to 
change it..... HEY look at that! sshd must be where to do that. Is all I have 
to do is change the number by the word 'Port'? (it has a 22 next to it now)

Then there is the line that says: 'permit root login yes' Should I change that 
one to no? If I do that what will happen to sudo and when I need to log roots 
account into a termnal?
