Unix Servers Used in This Class  Two Unix servers set up in CS department will be used for some programming projects  Machine name: eustis.eecs.ucf.edu eustis2.eecs.ucf.edu  You can connect to them only in campus network If outside, set up VPN to campus network first Read the following webpage to learn how to setup VPN etwork-services/vpn/ etwork-services/vpn/ Introduction 1-1

Basic Usage of Unix  You only need to remember a few basic commands for using the Eustis machine for this class  Editor: pico (or edit on your computer and upload the code to eustis)  Command: cd, mkdir, rmdir, chdir, cp, rm, ls, man,  There are many tutorials online    Command line reference: Introduction 1-4

Basic Usage of Linux  You can use PuTTY to open many independent shells  For the program project 1, you can run client code on one eustis machine, and the server code in another eustis machine. Introduction 1-5
