DESCRIPTION
This manpage is a place holder until something better is written when
the netscript itself has stopped changing rapidly.
Please see the README file in the /etc/netscript directory, and READ
the configuration files if you need to change them. Apart from
network.conf, all of them contain
sh (1) shell script functions which are there so that various things can
be altered or hooked in at the right place. Network.conf contains the
full network setup details, including special interface setup for the
likes of ciped/pppd/wanconfig, and is fully commented with examples
given.
UPGRADE PATH FROM KERNEL 2.2.X
The firewall/IP filtering stuff in ipfilter.conf is the part that changed
radically with the move to iptables and a far better way of setting up the
IP filtering rules, however the QoS and interface startup/shutdown in if.conf
have changed but are backwards compatible with the old 2.2.x ipchains version
of netscript for the interface address configuration settings. You will have
to set up the filtering again to use iptables by directly using the iptables
commands.
Also, the kernel 2.2.x version scripts are set up so that iptables is only
run on a 2.4.x kernel, otherwise IP forwarding is disabled if beforehand
you set IPFWDING_KERNEL to FILTER_ON in network.conf.
This means that when you upgrade a box to a 2.4.x router kernel, you should
then be able to reboot it and log into remotely and upgrade netscript to the
version that will support 2.4.x. In this situation, if you have set
old IPFWDING_KERNEL setting to FILTER_ON beforehand in network.conf, all
IP forwarding through the box will also be disabled. This means that you
can safely remotely upgrade a firewall.

The author is lazy. He needs to write btter man pages...
