4. Agreement Form • Require a signature on the Pre-requisite / Co-requisite Agreement. • Pre-requisite: Freshman status • Co-requisite: CSCI 1410 Fundamental of Computing

5. CSCI 1411 Canvas Site • Announcements • Syllabus/Schedule • Labs and Assignments (Modules) • Canvas for Homework Submissions (do NOT need to use VPN for Canvas)

6. Course Introduction Goals • To gain skills in computer programming with the C++ language using a UNIX operating system Grading Policy • 14 Labs worth 40 points each: • Pre-lab assignments worth 5 points • Programming component worth 35 points (see syllabus) • No exams Assignments • Each lab must be completed and turned in by start of class one week after assigned (exception is last lab of semester). • All work must be turned in on Canvas

7. How to Access Windows & Mac PCs in Lab • Lab PC login • User IDand Password are the same as you use to log into the UCDAcess portal and your UCD email account. • Note you will using this same account to log into the Unix server.

8. How to Access CSE Unix Servers • Contact for problems involving your CSE account. • Helpdesk system: csehelp.ucdenver.pvt • Or e-mail csehelp@ucdenver.edu

9. How to Get PuTTTY • PuTTY – A secure shell access client • Allows for remote terminal access to the Unix grid • http://www.putty.org/ • Already installed on the Lab Computers

10. How to Access Terminal Service 2) All programs -> 1) start ->

11. How to Access Terminal Service 3) PuTTY->

12. How to Access Terminal Service 4) PuTTY->

13. How to Access Terminal Service Host Name: csegrid.ucdenver.pvt CSCI 1411 Spring 2012

14. How to Access Terminal Service login as: UCD User Name

15. How to Access Terminal Service Password: UCD Password

16. Unix Terminal • What is UNIX? UNIX is an operating system (OS), software that manages the hardware and software resources of a computer. (Like Windows, Mac OS) • How will we use it? To write, compile, and execute C++ programs.

17. Trying Some of Unix Commands • Each of these commands is typed in after the UNIX prompt, and each is executed by pressing (Enter). Dir and file represent the pathnames of a directory and a file, respectively.

18. pwd command • Print working directory’s pathname • For example:

19. mkdir command • Make a directory having the pathname Dir • For example: mkdircsci1410 mkdir csci1411 mkdir~/temp • create a directory at student’s home directory

20. ls command • List files in the current directory • For example: ls ls -l • ls -t

21. rmdir command • Remove (i.e., delete) the directory Dir • For example: rmdircsci1410rmdir~/temp

22. cd command • Change to directory having the pathname Dir • For example: cdcsci1411(and then try ls and pwd command to see the output ) cd (and then try ls and pwd command to see the output )

23. mv command • Move file into the directory Dir • For example: mvindex.html csci1411 (and then try these commands to see if file is moved) cdcsci1411 ls

24. UNIX Text Editors • nanonanofile_name Example: nanomy_first_file.cpp • vivifile_name

25. Accessing UCD Grid Files • WinSCP • Manage files on the UCD Grid • http://winscp.net/ • Already installed on the Lab computers

26. Accessing UCD Grid Files • File Transfers • WinSCPto csegrid.ucdenver.pvt(this doesn’t work until you log in using sshfor the first time, otherwise your home directory will not have been created) • (Windows) Connect to: \\csenas.ucdenver.pvt\<username> from Windows desktop and copy files to home directory • (Mac) Connect to: SMB://csenas.ucdenver.pvt/<username> from a Mac finder window and copy files to home directory.

27. Download/Upload files using WinSCP • Start  All Program  WinSCP  WinSCP • Enter Hostname: csegrid.ucdenver.pvt • Enter Username & Password used for University login 

28. Download/Upload files using WinSCP • Drap & Drop files between two windows to download/upload file into UCD Server Your PC UCD Server

29. Accessing CSE Servers from off campus 1. Install Virtual Private Network Used to connect to the UCD networkhttps://itservices-web.ucdenver.edu/VPN/ 2. Use your University Account to Authenticate 3. Download the Correct Version of the VPN based on your home computer OS version.

30. Accessing Terminal Services • Basic terminal access (if off campus turn on VPN first, if on campus don’t use VPN): • Connect to the load balancer csegrid.ucdenver.pvtvia ssh using the client of your choice (This will forward you to one of the six blades based on a round-robin algorithm)
