Hi,
I have written a very simple program to add iptables rule, but I am
kept getting " Too many levels of symbolic links" .
Does anyone know what is wrong?
int ret = 0;
iptc_handle_t h = iptc_init("nat");
struct ipt_entry_match *match;
struct ipt_udp *match_udp;
struct ipt_entry_target *target;
char callee_inhibitor_buf[IPTC_FULL_SIZE];
struct ipt_entry *entry = (struct ipt_entry *) callee_inhibitor_buf;
memset(entry, 0, IPTC_FULL_SIZE);
entry->ip.proto = IPPROTO_UDP;
entry->ip.src.s_addr = inet_addr("192.168.3.2");
memset(&entry->ip.smsk, 255, sizeof(struct in_addr));
entry ->ip.smsk.s_addr = 0xffffffff;
entry->ip.dst.s_addr = inet_addr("200.168.3.3");
entry ->ip.dmsk.s_addr = 0xffffffff;
entry->target_offset = IPTC_ENTRY_SIZE + IPTC_MATCH_SIZE;
entry->next_offset = IPTC_FULL_SIZE;
match = (struct ipt_entry_match *) entry->elems;
// match = (struct ipt_entry_match *)entry->elems;
match->u.user.match_size = IPTC_MATCH_SIZE;
strcpy(match->u.user.name, "udp");
match_udp = (struct ipt_udp*) &match->data;
match_udp->spts[0] = 5060;match_udp->spts[1] = 5060;
match_udp->dpts[0] = 5070;match_udp->dpts[1] = 5070;
target = (struct ipt_entry_target*) (match + IPTC_MATCH_SIZE);
target->u.user.target_size = IPTC_TARGET_SIZE;
strcpy(target->u.user.name, "ACCEPT");
ret = iptc_append_entry ("PREROUTING", entry, h);
if (!ret) {
printf("append : %s\n", iptc_strerror(errno));
}
ret =iptc_commit(h);
printf("commit =[%i]\n", ret);
if (!ret) {
printf("commit: %s\n", iptc_strerror(errno));
}
