Strang activity at auth.log (POSSIBLE BREAK-IN ATTEMPT)
Hello! I found a strange activity at my var/log/auth.log
Looks like somebody would like to break my account
Address 126.96.36.199 maps to no-reverse-dns-configured.com, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!
There are a lot of such records in this log. How can I solve this problem or how can I be sure that my account is protected?
