iptable default "filter"? What is it?
 

Hi all,

I am currently trying to setup a firewall using iptables on my board, however, if I enter the commands for iptable, the message shows:

/>iptables v1.2.7a: can't initialize iptables table `filter': iptables who? />(do Perhaps iptables or your kernel needs to be upgraded.

What is this filter it is speaking of? I know that on RedHat9.0 that this filter seems to be located at:

/etc/sysconfig/iptables

So do I just copy this file onto uClinux or there is more to be done? Can I construct this "filter" file? Directions and suggestions are much appreciated.

do you also have ipchains installed? Uninstall it.

the popular filter is iptables :)

www.netfilter.org will give you a better understanding about iptables.

just copying the file won't help; the filters need to be written around your system.

never mind, i figured it out. thanks for the reply tho

the CONFIG_IP_NF_FILTER module must be include to build a default filter.

anyway, now that is out of the way, i continue by writting a sample script that is to be ran after booting. it got through. the next question is,
how can i check if the firewall is up and running? check with "ps" command?

Thanks
