[OpenSIPS-Users] Sipcapture issue

[Flavio Goncalves]

Hi Alexander,

I had exactly the same problem.  I'm sending to your email the pcap file.
Actually I don't think the problem is the request. I have inspected the
pcap file and seems fine according to HEP v2. I've changed the source code
to force UDP and it worked fine after that. It is is not a patch, only a
workaround, the root cause is still to be found.

  /* PROTO */
        if(heph->hp_p == IPPROTO_UDP) ri->proto=PROTO_UDP;
        else if(heph->hp_p == IPPROTO_TCP) ri->proto=PROTO_TCP;
        else if(heph->hp_p == IPPROTO_IDP) ri->proto=PROTO_TLS; /* fake
protocol */
#ifdef USE_SCTP
        else if(heph->hp_p == IPPROTO_SCTP) ri->proto=PROTO_SCTP;
#endif
        else {
                //LM_ERR("unknow protocol [%d]\n",heph->hp_p); /*Workaroud
*/
                ri->proto = PROTO_UDP; / *Workaround */
        }

The problem seems to be in the IPPROTO_UDP definition. The message shows:

ERROR:sipcapture:hep_msg_received: unknow protocol [1]

Best regards,

Flavio E. Goncalves
