1. 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 https://www.cst.ucf.edu/about/telecommunications/n etwork-services/vpn/https://www.cst.ucf.edu/about/telecommunications/n etwork-services/vpn/ Introduction 1-1

2.  Need to use SSH to remote login  SSH free software (many many others): Command shell client: PuTTY http://www.putty.org/ File transfer: WinSCP (for windows) http://winscp.net/eng/index.php http://winscp.net/eng/index.php  Student can log in using default password Pyymmdd (birth year, month, day).  The login user name is student NID  For any login problems, please email help@eecs.ucf.edu Introduction 1-2

3.  This remote login will create a “shell” command-line window in your own computer  You can only use keyboard to type in command line in this shell window to let remote Unix server to execute  Unix also supports GUI-based remote login (similar to Windows “remote desktop”), but it is complicated to use Introduction 1-3

4. 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  http://www.ee.surrey.ac.uk/Teaching/Unix/ http://www.ee.surrey.ac.uk/Teaching/Unix/  http://freeengineer.org/learnUNIXin10minutes.html http://freeengineer.org/learnUNIXin10minutes.html  Command line reference: http://www.pixelbeat.org/cmdline.html http://www.pixelbeat.org/cmdline.html Introduction 1-4

5. 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
