I have two machines, both with permanent IP addresses. One machine (the Client) needs to frequently access the other (the Server) using SSH. This works fine, however the server is configured with
UseDNS yes. The along the way something does not map back to what it should, and my logs keep getting filled with "POSSIBLE BREAK-IN ATTEMPT".
I can prevent this by turning off UseDNS, but I think would rather do it selectively for just this one client that I know is safe. Is there any way to do this?
