Is this because the packet is not in a state where it can be marked, or am I doing something stupid? My code is: int nfmark = 255; setsockopt(fd, SOL_SOCKET, SO_MARK, (int *) &nfmark, sizeof(int)); The following lines of code in the same place work okay to set the TOS: int nfmark = 255; setsockopt(fd, IPPROTO_IP, IP_TOS, (int *) &nfmark, sizeof(int)); 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
