I don't know why you are getting segfaults when you run your code (and right now I lack the necessary tuits to download it and find out). Your description of the problem is good though and I can make a suggestion or two based on that.

The fact that the ping program you need to use doesn't implement timeout is making your program very complicated, because you have to clean up hung child processes. Signals can help you here (though they may be causing you other grief, see next para), try setting the alarm clock to wake them up again. Then kill them. It's morbid, but what can you do?

I don't know why your sleep call doesn't seem to be working, but you can't use it with alarm.
