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;
 }
}

I've been getting nmap crashing on some W2K and WXP boxes.  This does not
happen on all of these type boxes but exclusively with Beta30.  Beta29 does
not seem to have this problem.

Any ideas?

if you want a version of nmap that runs under win32 you can download it from
my website  www.testic.co.uk
