For this lab exercise, you will learn about some UNIX commands for getting information about internet hosts, domains, and routing. These commands are described the web page Networking Tools. Spend a few minutes loking over these commands to get an idea what they do and how to use them.
The exact syntax of these commands varies from one UNIX machine to another. The web pages describe their use on our csdev machines, so you will need to log into one of these machines.
If you are working from a UNIX platform you can use the
ssh command to start a secure login shell to a csdev
machine.
These machines have host names of the form
csdevnn.d.umn.edu,
where nn is a two digit number from 01 up to 22.
If you are working on a Windows platform you can use the PuTTY program to start
a secure login shell.
Your TA will describe how to start this program.
After you have established a secure loggin to a csdev machine, follow the instructions and write down answers to each of the questions in the following sections. You should turn in your answers at the end of the lab period. B sure to put the course and your name and student ID at the top of the paper that you turn in.
Use ping to answer the following questions.
Use nslookup to answer the following questions.
Begin by using traceroute to get route traces to the following locations.
Also answer the following questions. The answers are out there on the network. You can find them using either network searches or clever guesses for web site URLs.
