NETSCRIPT version 5.3
The firewall and network configuration system for advanced Linux
firewalls/routers, and it is NOT meant to be used on servers!
Copyright 1995-2014 Matthew Grant <matt@mattgrant.net.nz>
1998,1999 Dave Cinege <dcinege@psychosis.com>
This script system for network setup has its roots in the original firewalling
setup that Matthew Grant did for a firewall using kernel 1.2.x. Since then
it has been evolved through firewalls/routers on Linux kernels 2.0.x, 2.2.x
2.4.x, 2.6.x, and 3.x.
Version 1 was the stuff under kernel 2.0.x, version 2 on LRP 2.9.4 Kilimanjaro,
Materhorn, and Eiger under 2.2, version 3.0 for Debian under kernel 2.2.x, and
this one is for Debian under kernel 2.4.x and 2.6.x.
You should install bridge-utils for bridging, iproute2 tools and iptables to
use these scripts. Your kernel will need to be compiled for Advanced Router
support and have almost the configuration options turned on. It is also
recomended that routing software like zebra be installed on the system as it
will make things like static routing and complex routing a lot easier to
handle.
A kernel configuration of what is needed can be found in 2.4.x-kernel.config
It is also a good idea to add kernel patches from the iptables source tar ball,
especially the IPv6 ones for logging support. The scripts will load all the
neccessary modules for QoS and iptables.
Documentation for this system is sparse at the moment, but more will be done
when the time is found to do it.
When installed, most of the configuration you will need will be found in
/etc/netscript/network.conf including lower level protocol
daemons/configuration programs like ciped, pppd, or wanconfig.
You will have to configure the firewall using the iptables commands directly.
Don't forget to save the configurations using the
'netscript ipfilter|ip6filter save' commands! Unlike the last version,
the firewalling and filtering is no longer configured from network.conf.
This has been done as stateful filtering obviates the need for great
complexity in the firewall scripts, and more flexibility is possible.
You have to get down and get dirty with iptables and learn it, which is a
good thing to do if you are running this to build a network - you should
understand things fully, or else you will get things wrong.
