Hi,
I've been trying for days to link a filtering module to the kernel. My =
module simply registers an hook and mangle incoming packets.
I've installed a 2.4.5 kernel source, and iptables-1.2.2, compiled the =
Kernel and
followed the INSTALL instructions in iptables.
=20
I've compiled with
=20
gcc -o6 -Wall -DCONFIG_KERNELD -DMODULE -D__KERNEL__ -DLINUX -c =
mymodule.c

But when i insert the moudle with
=20
insmod mymodule.o

it returns=20

Unresolved symbol :  nf_register_hook
Unresolved symbol :  nf_unregister_hook
Unresolved symbol :  printk

What am I missing ?=20
Thanks =20
