If IPsec default policy is configured for destination
traceroute will never success (because encrypted icmp timexceeded
is unrecognizable).

Only require half of the responses to indicate that the destination is

unreachable. This makes traceroute exit when it encounters a Cisco, which
typically does not respond to every other probe (or so) when either there
is no route to the destionation or an access list is blocking the probes.

Check select() return value, and abort the program if an error is

returned. Otherwise after sending a packet, select() may return
immediately (if there's an error of some sort) and traceroute
solders on, sending more packets with no delay in between. This is
effectively a small flood attack.
