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.
