Bill,
I am surprised you would think I have no firewall. As long as I have had the
server (2 years), I have had PF installed and running, and I can tell you
exactly which incoming ports I have open to the net:
tcp_services = "{ ssh smtp www https 4661 4662 52550 }"
the last three are for edonkey and bittorrent, resp.
c'est tout.
There are no *obvious* weaknesses, ie, ssh is private-key only.
That being said, I leave the WiFi open to everyone, with the following ports
available:
wifi_tcp_services = "{ ftp ssh bootps whois domain www imap imaps ntp irc
https sunrpc dict nfs 2628 3689 4711 6667 6909 23398}"
Should I entertain the possiblity that someone parked their car near my
house and hacked in through one of the above ports?
Any suggestions as to where to start looking for the breach would be most
welcome; I am quite new to this game.
Thanks.
