31#
32# This may fail due to:
33#
34# 1. A change to the ip stack breaking expected probe behavior,
35#    which is the reason we are testing.
36# 2. No physical network interface is plumbed and up.
37# 3. No other hosts on this subnet are reachable.
38# 4. An unrelated ICMP between these hosts was traced by accident.
