Newbie - Firewalls
I have a linode (running debian) mainly used for small services (apache, mail, ftp etc), and was wondering if I needed to set up a firewall, or is that automatically done when the image is created?
If so, what do I have to do to get a firewall in place?
Regards,
Peter.

I don't think there are any unnecessary services running in the default Debian install, but there is no firewall as far as I know. I believe the easiest way to get one running is 'apt-get install bastille' which will tighten up a number of things besides activating some iptables rules.
The config file can be as easy as :
version 5
interface eth0 internet
server "ssh www" accept
client "dns" accept
and then running firehol.sh try will enable those rules above,
