Bug 46 – /etc/init.d/ipfilter script

• Status: RESOLVED DUPLICATE of bug 2355
• Product: Gentoo Linux

[Description Mikael Hallendal (hallski) (RETIRED) 2002-01-06 03:59:04 UTC]

I think it would be nice to have a /etc/init.d/ipfilter script that excecutes a
/etc/ipfilter/rc.firewall on start and /etc/ipfilter/flush.firewall on stop.
That way you don't have to edit files in /etc/init.d to setup your firewall.

Created attachment 27 [details]
ipfilter init-script

might need some love but I'm not a good bash-programmer :)

[Comment 2 Daniel Robbins (RETIRED) 2002-01-06 21:51:28 UTC]

we could add a default firewall to /etc/conf.d, but it really should be integrated
into our new "net" design.

hmm .. noticing now that I wrote the wrong name, shouldn't be ipfilter, should
of course be iptables.

Anyway, an iptables-ebuild that depend on the net is probably what we want. If
the actual scripts lives in /etc/conf.d/iptables.{start,stop} or in
/etc/iptables/iptables.{start,stop} doesn't really matter to me.

Added Azarah to the CC-list of this issue.

Good idea would probably to place this "after" pcmcia (for all those who use
pcmcia networking) as well as depends on net.

as for the firewall script, some recommend mon-motha's scripts, or we could brew
our own one.

A nice easy to implement iptables script is gShield 
(http://muse.linuxmafia.org/gshield.html)

I've got it running under gentoo quite easily.

I vote to not include any default firewall rules.  So I won't.  Im gonna put
this together the best I can figure out.  Where should firewall state be saved?
 My first impression is to store it in /etc/conf.d/firewall, so I will.

depend() {
	need net
}

start() {
	ebegin "Loading iptables state and starting firewall"

	if [ ! -f /etc/conf.d/iptables ]
	then
		iptables-restore < /etc/conf.d/iptables
	fi

	eend $?
}

stop() {
	ebegin "Stopping firewall and saving iptables state"

	iptables-save > /etc/conf.d/iptables
	iptables -F

	eend $?
}


If this is good, here it is.  I just wanted to contribute. =)  Very simple
obviously.
