Linux uses UDP packets to traceroute, not ICMP packets like windows does.
Hope that helps,

Subject: traceroute-like tool for UDP or TCP packets

One of the local ISPs is having trouble getting DNS information from
Easydns. I suspect they have a misconfigured firewall or other security
block in their system. I can ping and traceroute the DNS servers but get no
response from UDP or TCP packets.

Is there a tool that works like traceroute, only shows the route for TCP or
UDP packets instead of the ICMP packets that traceroute uses?
