I've spent part of the evening testing this and checking its possibilities, the drawbacks that I see for this contribution are: * it uses the /proc entry, we have rejected similar add-ons in the past that have used these interfaces. * one single reader can be reading at a time. Having said that, I still think that the feature that this provides is useful, but I think that implementing this in user-space over nfnetlink_log results in a much more flexible solution. I have made proof-of-concept daemon (it's a quick hack of several hours) that implements the similar feature over nfnetlink_log, advantages are: * You don't need to upgrade your kernel / iptables. * You only need to install libnfnetlink, libnetfilter_log and the daemon. * It can be extended to support multiple readers. So my conclusion is that you can make this in userspace in a much more flexible way. You can find it here: http://1984.lsi.us.es/git/rlogd/ The initial commit provides some description on how to use it: http://1984.lsi.us.es/git/rlogd/commit/?id=ccb88a8dc8ad674b860f2d3edabf07fe4830baf3 I don't plan to develop / maintain that software. The last thing I want in my todo list is yet another thing to maintain. If someone is interested, please, feel free to grab it, make a nice website for it and maintain it. The repository also contains an unfinished patch to add LOG format support to libnetfilter_log. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
