Hi,
I am trying to write a small piece of code to obtain the packet count
and bytes count for a connection.
Here is what I get from conntrack -L
[root@linux]# conntrack -L -p udp -s 192.168.1.179 -d 192.168.1.115
--sport 10374
udp 17 88 src=192.168.1.179 dst=192.168.1.115 sport=10374
dport=26926 packets=850 bytes=170000 src=192.168.1.56
dst=192.168.1.115 sport=16395 dport=26924 packets=571 bytes=159880
[ASSURED] mark=0 use=1
=============
When I run the following source code, I get 0 for all caller_bytes,
callee_bytes, caller_packets, callee_packets, does anyone know what is
wrong with my code here?
uint32_t caller_bytes, callee_bytes, caller_packets, callee_packets;
int ret = 0;
struct nfct_handle *h;
struct nf_conntrack *ct;
ct = nfct_new();
if (!ct) {
perror("nfct_new");
}
switch_log_printf(SWITCH_CHANNEL_CHANNEL_LOG(channel),
SWITCH_LOG_DEBUG, "end_point_media_ip=[%s] end_point_media_port=[%s]
server_media_ip=[%s] se$
nfct_set_attr_u8(ct, ATTR_L3PROTO, AF_INET);
nfct_set_attr_u32(ct, ATTR_IPV4_SRC, inet_addr("192.168.1.179"));
nfct_set_attr_u32(ct, ATTR_IPV4_DST, inet_addr("192.168.1.115"));
nfct_set_attr_u8(ct, ATTR_L4PROTO, IPPROTO_UDP);
nfct_set_attr_u16(ct, ATTR_PORT_SRC, htons(10374);
nfct_set_attr_u16(ct, ATTR_PORT_DST, htons(26926);
h = nfct_open(CONNTRACK, 0);
if (!h) {
perror("nfct_open");
}
ret = nfct_query(h, NFCT_Q_GET, ct);
printf("TEST: query conntrack ");
if (ret == -1)
printf("(%d)(%s)\n", ret, strerror(errno));
else
printf("(OK)\n");
caller_bytes = nfct_get_attr_u32(ct, ATTR_ORIG_COUNTER_BYTES);
callee_bytes = nfct_get_attr_u32(ct, ATTR_REPL_COUNTER_BYTES);
caller_packets = nfct_get_attr_u32(ct, ATTR_ORIG_COUNTER_PACKETS);
callee_packets = nfct_get_attr_u32(ct, ATTR_REPL_COUNTER_PACKETS);
nfct_close(h);
printf("caller_bytes=[%lu] callee_bytes=[%lu]
caller_packet=[%lu] callee_packet=[%lu]\n", (unsigned
long)caller_bytes, (unsigned long)callee_bytes, (unsigned
long)caller_packets,(unsigned long) callee_packets);
Thank you in advance for all your kind help.
thanks,
P
