Whell, I'm trying to make a firewall and is incredible the problems that i'm havin. Althoug, by the time I have been able to solve all them with gentoo's forum help.

Whell when I choose all what to choose to enable iptables

Quote:


Networking Options -->

Network packet filtering (replaces ipchains)
IP:Netfilter configuration -->

all selected as modules exscept ipchains and ipfwd or something similar.


,while I'm compiling the kernel :

Code:
make dep && make clean bzImage modules modules_install


, it returns an error and stops. the error is:

Quote:

(····· gcc -D__KERNEL__ -I ····· )
ipt_realm.c: In function tclassid'
make[2]: *** [ipt_realm.o] Error 1
make[2]: Leaving directory /usr/src/linux-2.4.20-gentoo-r6/net'
make: *** [_mod_net ] Error 2


Has anybody any suggestion?

You might want to try unselecting realm match support

Then backup your .config file then run

make mrproper

And then your commands that you did before.

Be sure to backup your config file though ... because make mrproper will remove it.

I would suggest you back up your config, emerge the latest gentoo sources. r6 is old and it looks like your source tree is a mess anyway.

Code:

cd /usr/src/linux-2.4.20-gentoo-r6
cp .config ~
cd /usr/src
emerge rsync && emerge gentoo-sources && emerge -P gentoo-sources
rm -f linux
ln -s linux-2.4.20-gentoo-r8 linux
cd linux
cp ~/.config .
make menuconfig


(and so on)

Did you unselect realm match support

I have read a few times in these forums that causes some troubles and it did for me.

lots of thank, yes it was causing me many problems(realm match supp.). :evil:

I finally reinstalled Gentoo-linux. I selected all of the IP:Netfilter Configuration except:

    quake III protocol
    Realm match support
    ipchains
    ipfwdm (or something similar, well this is the last)


I selected all as modules, but i don't know what is best , as modules or putted into the kernel. Then i emerged iptables and after launched them all runs perfectly.

If anybody uses this to know what to compile to have iptables: OF COURSE you don't need all these modules. I would recomend you to take a look at this two pages, BOTH!!! not one.

http://www.linuxjournal.com/modules.php?op=modload&name=NS-lj-issues/issue89&file=4815s1
http://iptables-tutorial.frozentux.net/chunkyhtml/kernelsetup.html

And if you compile it manually probably this one too:
http://www.linuxjournal.com/article.php?sid=4815
And ofcourse you can find all them in:
http://www.netfilter.org

LOTS OF THANKS gorshing &mattsteven :wink:
