| Ausführliche Beschreibung | If running in a production environment, you might want to have a basic
firewall running on your dom0 to avoid having DoS attack. This is not the
state-of-the-art, but just another attempt to make things a bit more smooth.
Comments and contribution are more than welcome!
.
The main principle of this firewall script is to rate limit connections to
both your dom0 and your VPSes. It's principle is NOT block any connection. For
example, dtc-xen-firewall denies ssh for 300 seconds after 10 attempts on your
dom0, rate limit ping to 5 per seconds on your dom0 and to 50/s globally for
all your VPS, and does the same kind of thing for SYN flood attacks. Take
care, it also blocks any connection to the port 25, as in a normal dom0, you
would install a mail server to send system messages to the administrators, but
you don't want to accept any incoming message.
