Question

Identify the latency of a host over the local network, it should typically be in milliseconds; • Use the tools tracepath, traceroute and ping to determine the route trip times of packets to a host • Install the above tools if not on your system already Q) Can you run the following commands and compare the resulting times to the host www.flinders.edu.au; $ tracepath www.flinders.edu.au $ traceroute www.flinders.edu.au $ ping -c 10 www.flinders.edu.au Q) Identify which hosts/routers create the largest latency Q) Do you see asymmetric routes, if so why might that be? Q) Using tcpdump or wireshark, what type of traffic do these programs generate?

Answer 1

Q) Can you run the following commands and compare the resulting times to the host www.flinders.edu.au;

$ tracepath www.flinders.edu.au
$ traceroute www.flinders.edu.au
$ ping -c 10 www.flinders.edu.au

Q) Identify which hosts/routers create the largest latency

ix-ae-7-1333.thar1.1mh-sydney.as6453.net took largest time

Q) Do you see asymmetric routes, if so why might that be?

to redirect the traffic and avoid congesions.

Q) Using tcpdump or wireshark, what type of traffic do these programs generate?

UDP ICMP & TCP
