Good morning everyone!<br><br>Woke up this morning to emails from logwatch showing over a hundred <br>unauthorized ssh login attempts to my box this morning (all from the <br>same IP). I am wondering if there is any way, using the hosts.deny <br>file, that I can block out individual IP addresses from accessing my
box <br>at all?<br><br>Thanks!<br><br>_______________________________________________<br>nflug mailing list<br><a ymailto="mailto:nflug@nflug.org" href="mailto:nflug@nflug.org">nflug@nflug.org</a><br><a href="http://www.nflug.org/mailman/listinfo/nflug" target="_blank">http://www.nflug.org/mailman/listinfo/nflug</a><br></div><br></div></div><br>
