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.
