"--seconds" is just a match option, not something that defines the LRU's properties. And that's actually good, because that allows you to write -m recent --name foo --seconds 60 -j do that -m recent --name foo --seconds 3600 -j do something else If you purged "expired" entries after 60 secs, there would be nothing left for the 3600 one to check for. -- 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
