LINUX IPTABLE POCKET REFERENCE
Ouvrage 9780596005696 : LINUX IPTABLE POCKET REFERENCE
Firewalls, Network Address Translation (NAT), and network logging and
accounting are all provided by Linux's Netfilter system, also known by
the name of the command used to administer it, iptables. The iptables
interface is the most sophisticated ever offered on
Linux and makes Linux an extremely flexible system for any kind of
network filtering you might do. Large sets of filtering rules can be
grouped in ways that makes it easy to test them and turn them on and
off.
Do you watch for all types of ICMP traffic--some of them quite
dangerous? Can you take advantage of stateful filtering to simplify the
management of TCP connections? Would you like to track how much traffic
of various types you get?
This pocket reference will help you at those critical moments when
someone asks you to open or close a port in a hurry, either to enable
some important traffic or to block an attack. The book will keep the
subtle syntax straight and help you remember all the values you have to
enter in order to be as secure as possible. The listings of all iptables
options are divided into those suitable for firewalling, accounting, and
NAT.
