hello,
I was wondering if there's a way to enable some sort of key file
that only my windows xp will have when I connect to my
centos v4.4 server through SSH, so when I login as root
and I put my password and checks for the keyfile so
just in case someone hacks my password he cant get in
cus the keyfile is needed! is this possible ?
and if the tech wants to get in ill just disabled it!

Well, I already wanted same thing, seems impossible.
Refer http://www.experts-exchange.com/Security/Linux_Security/Q_21896950.html
What You can do is to authenticate ONLY with pubkey authentication - the private key is protected with password as well. Hence the real system password will not be used.
