Hello. Your solution works. It does not log to log file anymore.
Now I want to know how to stop 10.0.0.245 from using and connecting to the server. It seems that this 10.0.0.245 is a private IP address and I think its my management. Your solution only keeping the IP address off to log in the log file and keep blocking from connecting to the server.
I want to conserve energy or electricity by turning this IP address off.
