To retrieve the mark should I just be using: getsockopt(fd, SOL_SOCKET, SO_MARK, ...) ? I keep getting a mark of 0 despite setting a mark in PREROUTING. My code is as follows: int mark = 0; int marklen = sizeof(mark); getsockopt(newsocket, SOL_SOCKET, SO_MARK, &mark, &marklen); Thanks, Andy -- 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
