CSE 265: System and Network Administration

Homework #1

0. Make sure that you have an account on the CSE/ECE machines (Suns) and that you receive and read mail sent to you @cse.lehigh.edu. If you only want to read email in one place (recommended), you may want to set up a .forward on the Suns to send your mail to your Lehigh account (or vice versa).

1. Become familiar with a standard text editor -- either vi or emacs. What is the URL of the best web site resource/reference for the editor that you like?

2. What command would you use to read about the sync system call (not the sync command)?

3. How many different versions of ls are installed on the Suns, and where are they (that is, what is the complete path for each)?

Hint: you may need to use one or more of the commands: man, whereis, which to help answer this.

4. Why would one want hot-swap parts on a system without n+1 redundancy?

5. Why would one want n+1 redundancy if the system does not have hot-swap parts?
