SSH connection alert does not map back to the address-possible break-in attempt! Solution!

SSH connects to the remote server. The alarm information address x. x. x maps to localhost, but this does not map back to the address-possible break-in attempt! As follows:
[ Root @ Upgirl ~] # SSH Root @ 192.168.0.203
Address 192.168.0.203 maps to localhost, but this does not map back to the address-possible break-in attempt!
