Hi, I looking for good documention for writing or modifying netfilter modules. To be exact nf_contrack modules. The netfilter hacking how to seems outdated and incomplete. So any other documentaion which can help me? I'm interested in nf_contrack_sip module, which i will try to modify as my needs. I've tried to read the sources or nf_contrack_sip, but without a good background in netfilter core, it seems too much for me. Any advice or links to kind of documents i'm looking for will be more than welcome. Cheers. -- -aft -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
