Hi , We are looking at trying to retrieve the complete conntrack table using libnetfilter_conntrack API's. But when we used the below sequence of API's we see that the call back register is getting called once for every entery in the conntrack table. The sequence of API's we have used is as follows : cb .......... .......... nfct_snprintf ();<=====returns one entry from conntrack table .......... .......... main nfct_callback_register ( ); <===== NFCT_T_ALL to fetch all the enteries ret = nfct_query (); ........ ........ Is there a away for me to get the whole conntrack table in a single invocation of single callback function ? So that the cb function not called multiple times? Thanks and Regards,
