The cs161 user is using UnicornBox to store a file called ip.txt. cs161 is a special-purpose account on UnicornBox. It uses a separate login mechanism, so you won’t be able to log in as cs161, but you may still be able to change some of its files. Your task: Change the contents of cs161 user’s ip.txt file to be 161.161.161.161.

Start by downloading the source code: http://inst.eecs.berkeley.edu/~cs161/sp18/ projects/3/project3.zip. You will need the following software: After you have installed the necessary software and extracted the source code, open a termi- nal and enter the Project 3 folder.
