possibly compromised redhat 7.2 box

["Melissa McGillis" <mcgillim () cis uab edu>]

Hello,

I have a redhat 7.2 server that stopped accepting my ssh login. I can still
use my login at the terminal. I also noticed that the host key changed. My
only guess at this point is that the box was probably compromised. Any good
software out there to help me figure it out? Any other ideas as to what
would cause this?
Anything helps, 
Melissa
