[osip-dev] Endless UDP packets sent by eXosip

[Firman]

Hi Aymeric, all

I followed your advice and started learning eXosip instead of oSip ;-)

The doc is very clear, thanks Aymeric. I wrote the below program following the tutorial in the module section. I also compiled it and linked it against the c-ares library. Problem is, after the program finishes, it keeps generating UDP traffic (captured by Wireshark). Even after I rebooted my Ubuntu, the traffic still keeps being sent periodically. This must be caused by linking against the c-ares lib, no? Any idea how I can find the process spawned by the program and kill it? 

Thanks in advance.

#include <sys/socket.h>

#include <netinet/in.h>

#include <eXosip2/eXosip.h>

int registerClient(eXosip_t*);

int main(){

  // Initialize the osip trace (compile this code with -DENABLE_TRACE)

  eXosip_t *ctx;

  int i;

  int port = 5060;

  //TRACE_INITIALIZE(6, NULL);

  // Initialize eXosip (and osip) stack

  ctx = eXosip_malloc();

  if(ctx == NULL){

    return -1;

  }

  i = eXosip_init(ctx);

  if(i != 0){

    return -1;

  }

  // Open a UDP socket for signalling

  i = eXosip_listen_addr(ctx, IPPROTO_UDP, NULL, port, AF_INET, 0);

  if(i != 0){

    eXosip_quit(ctx);

    fprintf(stderr, "could not initialize transport layer\n");

    return -1;

  }

  eXosip_set_user_agent(ctx, "Firman Test");

  registerClient(ctx);

}

int registerClient(eXosip_t *ctx){

  fprintf(stdout, "Register client\n");

  // Initialize a registration

  osip_message_t *reg = NULL;

  int rid;

  int i;

  eXosip_lock(ctx);

  rid = eXosip_register_build_initial_register(ctx, "sip:address@hidden", "sip.antisip.com", NULL, 1800, &reg);

  if(rid < 0){

    fprintf(stderr, "Unable to build initial register\n");

    return -1;

  }

  osip_message_set_supported(reg, "100rel");

  osip_message_set_supported(reg, "path");

  i = eXosip_register_send_register(ctx, rid, reg);

  eXosip_unlock(ctx);

  return i;
