    Hi all,

       seems that in today's networking environment the original traceroute
    concept utilising high UDP ports no longer works - since those ports
    are now typically blocked by firewalls.

       However, when traceroute is performed using ICMP protocol, the results
    are much better.

       Therefore, I'd like to propose to patch

    src/contrib/traceroute/traceroute.c

       so the ICMP protocol is the first one in

    struct outproto protos[] = {

       and thus the default protocol used by traceroute.

            With kind regards,

                    M.
