Getting ping closer.

I apologize for all the debug junk in here, it will come out, I
am hoping someone can show me the error of my ways.

config up the loopback device:
cat /9/net/ipifc/clone
myecho  /9/net/ipifc/$i/ctl "bind loopback /dev/null "
myecho  /9/net/ipifc/$i/ctl "add 127.0.0.1 255.0.0.0 127.0.0.0 "

or whatever

and
ping 127.0.0.1
and watch it die.
