Re: [Gumstix-users] iptables on Overo

[Joseph H. <jos...@gm...>]

I have iptables up and running, but I find that it is having problems with
using the fields within the TCP protocol. For example, this command executes
without error:
     iptables -A INPUT -p tcp -j ACCEPT
However, when I try to specify a port:
     iptables -A INPUT -p tcp *--dport 22* -j ACCEPT
     iptables: No chain/target/match by that name.

In OVEROTOP/tmp/sysroots/armv7a.../lib/modules/2.6.34/kernel/net/netfilter/
I see a lot of modules I've compiled along with my image, including
xt_tcpudp.ko. If I insmod this module, that second rule works.

Why are these modules not being put into the rootfs/kernel? Is there a way
to specify that this module should be included? (And are there other modules
I should make sure get included?)

If not, what is the preferred way of making sure it gets loaded on each
boot? I've looked at /etc/modules and /etc/modules.conf. Aside from not
knowing which I should use, they both also say not to edit them manually
because they are autogenerated via files in /etc/modutils/. However, I don't
have that directory.
