# Test ip:::{send,receive} of IPv4 ICMP to a remote host.

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