I hit a wall with running this script. One problem is the different
versions of nc for debian (stretch to be specific), and another problem
is commands failing it is hard to figure out why (e.g., connect failures
which seem like route lookup problems). I have been adding run_cmd and
PAUSE_ON_FAIL options similar to what is in fib_tests.sh and the change
I sent for pmtu.sh, but I have not finished.

I am traveling tomorrow and not sure how much time I'll get this weekend
to come back to this. Might be early next week.
