Sending and receiving raw ICMP requires a raw socket. Since it is
unwise to allow the casual user this sort of low-level access to the
network, opening a raw socket requires root privileges.
This is why, for example, the Perl Net::Ping module defaults to using
the TCP echo port to determine IP connectivity rather than raw ICMP:
there's no such issue when opening a TCP socket.
