Hi, Following is an attempt to add an entry into the kernel routing table using ioctl ..... it give errno = EOPNOTSUPP. I understand that this means there's some problem in the rtentry parameter I'm passing to ioctl ... but for the world of me I can't understand how to make this work!!! Help greatly appreciated.......... --A ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- ---------------- add_entry(char *srcIPaddr) { int err; struct rtentry *rt; struct sockaddr_in *s; int sockfd; struct sockaddr_in gway; srcIPaddr = "4.5.6.7"; memset(&gway, 0, sizeof(struct sockaddr_in)); gway.sin_family = AF_INET; gway.sin_addr.s_addr = inet_addr("2.3.4.1"); s->sin_len = sizeof(struct sockaddr_in); s->sin_family = AF_INET; s->sin_addr.s_addr = inet_addr(srcIPaddr); rt = (struct rtentry*)malloc(sizeof(struct rtentry)); memset(rt, 0, (sizeof(struct rtentry))); rt->rt_flags |= RTF_HOST; rt->rt_gateway = (struct sockaddr *)&gway; rt->rt_flags |= RTF_UP | RTF_GATEWAY; rt->rt_use = 0; rt_key(rt) = (struct sockaddr*)s; fwd_enable(1); sockfd = socket(AF_INET, SOCK_DGRAM, 0); if( ioctl(sockfd, SIOCADDRT, rt) < 0) { if (errno != EINVAL) { printf ("ioctl error :%d\n", errno); } } } To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
