hi This mornning I find some ip address listed in the "System auth log" section in my daily root mail. I've been new to linux and I would be glad if someone can tell me why are those IPs listed, and most importantly: would it be a crack? If it was, what to do next? Thanks ------------------------------------ Connections: Service auth: 66.154.80.100: 1 Time(s) 192.168.0.1: 1 Time(s) 212.204.214.114: 1 Time(s) 216.55.156.62: 2 Time(s)
