Itrace is a program that implements traceroute(1) functionality using ICMP echo request packets. Therefore, it looks like you are just pinging your target while you traceroute there. It often helps tracing behind firewalls.

Because backtrack running under virtual machine in virtualbox, I couldn’t run this under ubuntu installation.

command: itrace -i eth1 -d yahoo.com

eth1 being your ethernet device.

That’s it.
