Re: nmap under win98

["Andy Lutomirski" <Luto () myrealbox com>]

This should do it:

Change readip_rawrecv in rawrecv.c to this:

[note to fyodor:  I'm fairly sure I already sent you this]

char *rawrecv_readip(pcap_t *pd, unsigned int *len, long to_usec)
{
 int rcvlen;
 DWORD time1, time2;
 fd_set fds;
 TIMEVAL tv;

 if(-2 != (long)pd)
  fatal("rawrecv_readip: called with non-rawrecv handle\n");

begin:

 // Note: I could use SO_RCVTIMEO but I don't trust it...
 time1 = GetTickCount();
 FD_ZERO(&fds);
 FD_SET(s, &fds);
 tv.tv_usec = to_usec % 1000000;
 tv.tv_sec = to_usec / 1000000;
 if(0 == select(0, &fds, 0, 0, &tv))
 {
  if(len) *len = 0;
  return 0;
 }

 rcvlen = recv(s, buf, sizeof(buf), 0);
 time2 = GetTickCount() + 10;

 if(rcvlen > 0)
 {
  if(rcvlen >= sizeof(struct ip) && filter(buf, rcvlen))
  {
   if(len) *len = rcvlen;
   return buf;
  }
  else
  {
   to_usec -= 1000 * (time2 - time1);
   if(to_usec < 0)
   {
    if(len) *len = 0;
    return 0;
   }
   goto begin;
  }
 }
 else
 {
  DWORD err = WSAGetLastError();
  if(err != WSAETIMEDOUT && err != WSAEWOULDBLOCK)
   fatal("rawrecv: recv failed (%lu)\n", err);

  if(len) *len = 0;
  return 0;
 }
}
