Hi Folks,
I would recommend all newbies turn on their firewall.
ufw is installed with ubuntu, The graphical front end for it is not. You can install it with
Code:
sudo apt-get update && sudo apt-get install gufwLaunch the gufw from a terminal with sudo and select the 'Home' profile and enable the firewall. It will block all incoming network traffic and allow all outgoing. So everything still works. You can add rules for any legitimate incoming traffic if needed. I turned it on yesterday and it logged 574 incoming packets. Some automated ssh username / password guesser i imagine.
Better safe then sorry even if you're not running any internet enabled daemons.
I don't know how the runlevels work in ubuntu, but the firewall survived a restart so I'm happy.
Just my newbie $0.02
