Thanks in advance

Hi Jonh, I was reading your iptc post and was wondering if you could help, as i’m totally stuck.
i’m trying to emulate :: iptables -A INPUT -t filter -p tcp -j NFQUEUE –queue-num $queueNum
where $queueNum is any int
so far I have
static int createFilters(int baseNumber) {
/*
* input filter looks like this
* iptables -A INPUT -p tcp -j NFQUEUE –queue-num 0
* sudo iptables -L INPUT
* Chain INPUT (policy ACCEPT)
* target prot opt source destination
* NFQUEUE tcp — anywhere anywhere NFQUEUE num 5
*/
const char *table = “filter”;
const char *chain = “INPUT”;
const char *target = “QUEUE”;
struct
{
struct ipt_entry entry;
struct xt_NFQ_info {
u_int16_t queueNum;
} target;
} entry;
struct xtc_handle *h;
int ret = 1;
h = iptc_init (table);
if (!h) {
fprintf (stderr, “Could not init IPTC library: %s\n”, iptc_strerror (errno));
goto out;
}
memset (&entry, 0, sizeof (entry));
/* target */
entry.target.queueNum = XT_ALIGN (baseNumber);
entry.entry.target_offset = sizeof (struct ipt_entry);
entry.entry.next_offset = entry.entry.target_offset + sizeof(entry.target);
if (!iptc_append_entry (chain, (struct ipt_entry *) &entry, h)) {
fprintf (stderr, “Could not insert a rule in iptables (table %s): %s\n”, table, iptc_strerror (errno));
goto out;
}
if (!iptc_commit (h)) {
fprintf (stderr, “Could not commit changes in iptables (table %s): %s\n”, table, iptc_strerror (errno));
goto out;
}
ret = 0;
out:
if (h)
iptc_free (h);
return ret;
}
but it won’t commit. Any thoughts?
Thanks,
Mat
More Istio posts please : )
Hi John,
I am working with Istio right now and your walkthrough issues and how to solve it have been really helpful to understand how it works and for sure how to solve my issue.
Just taking a minute to say Thanks for your posts man, you rock!
