Re: I'm chinese I want to get help about iptables

> ip_tables.0:insmod iptables.o init_module:Device or resource busy

(I am assuming you are using a 2.4 kernel.  2.2 did not have iptables

"Resource busy" might mean you are already using ipchains or ipfwadm.
You can use only one of the three at the same time.

If the fw interface you are already using is provided in a module, you
can rmmod it (after stopping to use it) and use another one.

But if it is built into the kernel, I believe you have to reboot
before you can use one of the other interfaces.  (Just make sure it is
not used again by a boot script.)
