IP_TABLES ERROR

arachn1d · Posted: Mon Apr 19, 2004 5:36 am Post subject: IP_TABLES ERROR

I can't get ip_tables to work with my system

keeps giving me errors
An error occured when checking your current IPtables configuration :

modprobe: Can't locate module ip_tables
iptables v1.2.9: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

This may indicate that your kernel does not support IPtables

with webmin and even by hand

I re-cnofigured the kernel to support it even added everything there but still no luck anyone help plz?
or can someone point me in the direction of another good firewall...?

Please can you post your dmesg? You and we) can see IF your kernel is loading IPTABLES. Furthermore you should:

Try to compile kernel iptables support as modules, if it is not so already. You may also try re-emerging iptables.

this error messages says, that you have forgotten activate
Networking Options --> Netfilter Configration --> Packet Filtering
in the kernel.

so activate it and compile the kernel. then it will work.

then there might be three possibilieties:
(1) a missmatch between your version of iptables and the kernel
(2) restrictions to access kernel parameters (normally also kernel based!).
(3) a typical computerproblem like "it does not work, but there is no reason. but someday it will work and we do not know why."

If you compile your kernel by hand the config file is /usr/src/linux/.config. If you use genkernel it is in /etc/genkernel or something like that.

In make menuconfig (or genkernel --menuconfig), under Network Options, do you have [*] Network packet filtering (replaces ipchains)? Then, under IP: Netfilter Configuration ---> make everything [M] as Janne Pikkarainen suggested. Then follow the normal procedures for compiling the kernel as given in the handbook.

If you have a separate boot partition you have to mount it before you copy a new kernel to it. Otherwise it's as good as copying it to /dev/null, the kernel won't be were your boot loader is looking for it. If you still have everything compiled built in the kernel, you won't have the modules, and most probably not the directory.
