Subject:   Making ICMP the default traceroute protocol?
Message-ID:  <20050124160242.GA91593@us.svf.stuba.sk>

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.
