che forse non centra niente. Siccome non sono un grande esperto, significa che qualcuno ha cercato di accedere al mio PC di casa ?
Credo senza riuscirci. Ci sono altri file di log che mi possono dare ulteriori informazioni ?
Ha casa ho un router wireless dlink (192.168.1.1) al quale è collegato il mio pc (192.168.1.2). L'IP pubblico attuale è 78.14.41.24.
L'abbonamento ADSL è con tiscali. Avevo attivato il port forwarding sul router della porta 22 all'host 192.168.1.2, volevo provare a collegarmi al
computer di casa dall'ufficio. Qualcuno ci stava provando prima di me ???
Ovviamente ho disattivato sshd.
