i've just tried keeping a log of who is trying to break through my
firewall. astonished to see that someone is trying every few minutes.
who/what are these things? I'm running a well updated G4 powerbook, the latest OSX,
with Safari. What would happen if i didn't have this firewall up? Is
information i have stored in text files safe? ie unobtainable?

thankyou!!

PS here are a couple of the logs:
Apr  5 14:08:05 Adam-Barleys-Computer ipfw: Stealth Mode connection
attempt to TCP 10.0.0.11:49528 from 195.224.48.80:110
Apr  5 19:14:01 Adam-Barleys-Computer ipfw: Stealth Mode connection
attempt to UDP 10.0.0.11:51233 from 10.0.0.2:53
Apr  5 20:59:52 Adam-Barleys-Computer ipfw: Stealth Mode connection
attempt to UDP 10.0.0.11:16401 from 17.250.248.149:16384

In fact there is nothing serious. Maybe I should post my firewall log
here, indeed there is more than 5,000 'attack' per day for I am using
Firefox/emule all day long.
I have Nothing to worried about for I dont think a hacker will be
intrested in my love letters to my girlfriend or will steal my e-mails
to my Grandmather.
