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..........

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);
}
}
}
