Thumbs up Ubuntu Hardy defaults *most* ports closed w/o firewall

Thank You
That helped me as well, thanks. Apparently Unubtu 8.04 (Hardy) defaults *most* ports closed w/o firewall. I don't know the details (I'm a programmer, not an admin) but that's just the way it is!

Make sure to read the and secure your ssh-server so root login is disabled, etc.

Good luck!
