You need to understand a couple of things:

1- Windows machine uses icmp for traceroute by

default,

2- Unix/Linux machine uses udp high-ports for

traceroute by default,

Why don't you use the "-I" option in traceroute

for linux for icmp instead of udp-high ports?

gen2linux ~ # traceroute -n -I 4.2.2.2

traceroute to 4.2.2.2 (4.2.2.2), 30 hops max, 40 byte packets
