inject mode send same frames more than once

[Joshua Wright]

I had a similar problem, I think I resolved it by changing the retry value before transmitting the frames:

int hostap_set_retry(char *iface, int limit) {
  struct iwreq iwr;
  memset(&iwr, 0, sizeof(iwr));
  strncpy(iwr.ifr_name, iface, IFNAMSIZ);

  iwr.u.retry.flags = IW_RETRY_LIMIT;
  iwr.u.retry.value = limit;
  iwr.u.retry.disabled = 0;

  if (ioctl(harj->ioctl_sock , SIOCSIWRETRY, &iwr) < 0) {
    perror("ioctl[SIOCSIWRETRY]");
    printf("Failed to set retry limit to %d\n", limit);
    return(1);
  } else 
    return(0);
}

Subject: inject mode send same frames more than once


Hi list:
  I am using inject mode to send frames, but for each frames, it send out more than once which means I capture the same packet in the air for more than 4 or 5 times. Is there any configuration that I can change to send each frame only once.
  thank you.
