  12. Hi,
  13.  
  14. Sorry about this enormous number of repetitions.  But the second
  15. post had a correction in it.  Then I found I couldn't cancel the
  16. original one.
  17.  
  18. Anyway, here is what I found finally worked:
  19.  
  20. I needed to pack the option argument to setsockopt.
  21.  
  22. I was doing:
  23.  
  24. > setsockopt(S, &SOL_SOCKET, &SO_BROADCAST, 1);
  25.  
  26. What I needed to do was:
  27.  
  28. > setsockopt(S, &SOL_SOCKET, &SO_BROADCAST, pack("I", 1));
  29.  
  30. Why that worked on the Ultrix machine, I still don't know.  Does the
  31. Ultrix version of perl pack it for me?
  32.  
  33. Thanks to everyone who clarified this.
  34.
