All- I am building a LKM. I'd like this module to be a netfilter. I can build the module no problem. Upon trying /sbin/insmod I get the error "unresolved symbol nf_register_hook." Any thoughts? I've tried building the netfilter options in as modules and as part of the kernel. So far no luck. Some direction in this matter is greatly appreciated. Also if a sample .config file can be provided with netfilter propely configured, that would be great. Thanks, James
