This is not necessarily useful though: redirection happens in all kinds of ways and all kinds of places and while getpeeraddr(2) might tell you that you're connected to one of google.com's addresses, that could be far from the truth. (Of course, the inverse is true, just because you thought you were connecting to a local address doesn't mean that some wild and woolly iptables configuration didn't send your packets winging half way around the globe.) jch -- 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
