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. -------------------------------------------------------------------------- ---- ---- ---- Marian Durkovic network manager ---- ---- ---- ---- Slovak Technical University Tel: +421 2 524 51 301 ---- ---- Computer Centre, Nam.
