Some m/…./r constantly attacks my home NAS, trying all possible usernames and passwords – from Chinese IP address. Reminds me of a joke, when Chinese hackers tried to break into the Pentagon’s servers – each on of them tried password ‘Mao Tse-tung’, on a billionth attempt the server agreed that its passwords is indeed ‘Mao Tse-tung’. Weird, but this idiot keeps trying. Should I change my SSH port? Or what?
