While waiting for 4.3 BSD source code, I have been reading rfc's, etc, 
trying to figure out:

	 1)  whether icmp echo/reply messages can be sent with ip headers 
		 that specify strict source routing (via raw sockets only?),
	 2)  whether this would be useful in creating a looptest tool for 
		 customer service to check out specific serial links, and
	 3)  who has already implemented such an animal (probably only
		 about 50,000 people or so?).  I understand there's a program
		 called "ping" which uses echo.  Is it what I'm looking for?
		 Where can I get it?

Thanks in advance.
