Laboratory Policies

Attendance

    Attendance at all labs is mandatory due to the importance of the hands-on aspects of the course. Attendance sheets will be passed around at the beginning of each lab period. Failure to sign the attendance sheet will result in a

    penalty of 50% on the objective portion of the lab grade. Attendance sheets will be collected five minutes into

    the lab period. It is explicitly the student’s responsibility to sign the attendance sheet.

    Arriving at lab less than twenty minutes late will result in a 10% attendance penalty for the current lab project. Arriving to lab more than twenty minutes late will be considered an unexcused absence and will result in a 50% attendance penalty for the objective portion of the lab grade.

    Each student is allowed one excused lab absence per semester. Valid excuses include plant trips with advance notice and a copy of the plant trip offer letter, medical emergencies when accompanied by a doctor’s notice, and other valid excuses as verified by the Dean of Student’s office. The course professor must excuse your absence; the TA has

    absolutely no power to excuse absences. Any request to miss lab must be presented to the course professor at least one week in advance to the date of the absence in any cases where you know you will have to miss. If there is an emergency situation where you don’t know that you needed to miss class then the excuse is due to the course

    professor no later than two days after the missed lab date. In addition, any emergency excuses from a source of authority (e.g. doctor’s excuses) must include the date(s) affected and the signature of that authority.

Laboratory Access

    You will not have enough time to do all your lab work and report preparation in the structured two hour weekly lab time. To meet deadlines for submission of lab reports, you will have to devote additional out of class time to lab work. To facilitate out of class work the laboratory will be available for access by all enrolled students during normal scheduled C&IT laboratory hours.

Physical Access

    Later this semester the NET laboratories will be outfitted with a swipe access system. Once implemented, this system will allow students to enter the lab by swiping their Purdue Identification card at the door. You will be notified when the new system comes on-line.

    Until that time, to gain access to the laboratory you must trade your student ID for the Lab Responsibility Token or room key. The token is available at the main CIT office (Knoy 255) during business hours and at the consultant’s desk during evening and weekend lab hours. When you are the holder of the token you will be acting as a lab consultant, and must follow the lab consultant duties/rules:

    ; While you are the holder of the token, you are to be in the lab at all times. If you have to use the restroom,

    delegate someone to watch the lab during the BRIEF time you will be gone.

    ; Only authorized students are to be allowed in the lab. If there is a group of students in the lab making

    unwanted noise or demonstrating improper behavior, politely ask them to calm down or leave the lab. ; Nothing should be displayed on whiteboards or chalkboards except for passwords, login names, course

    information, etc. If you encounter graffiti, please remove it immediately.

    ; If for some reason you catch someone stealing something, first ask them to return the items, and if they refuse,

    write down their name, items taken, time, and date, and then contact the Purdue Police department

    immediately. Secondly, please contact the head C&IT lab consultant.

    ; When leaving the lab, make sure all lab equipment and software is put away, all monitors are turned off, the

    cabinet doors are shut, all lights turned off, the chairs and stools are pushed in, and doors are locked. ; Ad-hoc use of the laboratory is a privilege that will be revoked in the event that these rules are not followed.

     2

VPN Access

    Remote VPN access into the NET network (NET.lcl) is available to allow students access to all resources located on the NET network from home or other off-site locations. To connect, create a VPN connection in Windows to netlab.tech.purdue.edu. The authentication credential set is UID:netvpn and password:vpnclient. The server only

    supports encrypted data transmission using the CHAP, MS-CHAP, or MS-CHAPv2 authentication protocols. As

    Internet access is not available via the VPN unselect “use default gateway on remote network” on the

    advanced IP settings under the network tab.

This service is covered by the following usage policy:

    ; Any public posting of the VPN authentication credentials is strictly prohibited

    ; Access to the Internet via the VPN connection is not supported

    ; All connections and their origination and VPN IP address are logged

    ; As in the physical NET labs, launching attacks against production NET servers will result in immediate

    disciplinary action

    ; Similarly launching offensive attacks against other students’ machines unless specifically authorized will

    result in disciplinary action

    This service is a privilege being offered to all students. In the event that any of the above policies are violated this service will be terminated.

Laboratory Resources

    There are many lab sections that must share materials. Nothing is more frustrating and time consuming than being forced to waste precious lab time looking all over the lab to find a small but necessary piece of equipment or software. It is important that whenever you have finished with equipment, software, and documentation that it be placed back in the appropriate cabinet.

    In the event that a piece of equipment is suspected to have failed, carefully document the situation, your conclusion, and the evidence you’ve collected that leads to that conclusion and e-mail your lab instructor. The equipment in

    question will be examined and repaired or replaced as required.

Lockers

    Each laboratory group can be assigned a locker in the laboratory to store materials for use by the group. If you wish to lock your locker please use a non-hardened padlock so that it can be cut off in the event that everyone forgets the combination.

Software

    Operating system software is provided via CDs. Depending on the course, CDs will either be available in a cabinet in the lab or a CD wallet will be specifically assigned to your lab group. If you are using community software from the cabinet and an installation process is still running at the end of the laboratory section, someone from your lab group should stay until the install is complete to return the software or equipment to the cabinet. Take special care to ensure that all CDs are removed from the CD-ROM drives before leaving the laboratory.

If you receive a CD wallet your lab group is responsible for keeping track of it. Failure to check back in all CDs in

    the wallet at the end of the semester will result in a 5% reduction of your overall lab grade. If, for some reason,

    a CD won’t read in the CD-ROM drive contact the instructor and he/she will burn you a new copy of the needed software. If you don’t have the old CD a new CD will not be issued without a 5% deduction in your overall lab grade.

    In addition to the operating system software CDs there is an extensive software repository available on RTFM in the pub share. The file repository contains many utilities, patches, and software titles. Connect via anonymous FTP or browse to \\rtfm.net.lcl\pub with a username of “student” and a null password to access this resource.

     3

Additional Network Services

    There are several other services available on the NET network to enable you to perform your laboratory activities.

X.509 Certificate Services

X.509 certificates can be requested from the NET certificate server via the web. Connect to

    http://certsrv.net.lcl/certsrv to request a certificate. Certificate requests can be approved by any TA. To ensure that your request is approved promptly let your TA know that you have requested a certificate.

TFTP Services

    TFTP services are available on rtfm.net.lcl (172.17.8.11). The TFTP directory is accessible via the tftp-root share (//rtfm.net.lcl/tftp-root). There is no security on this directory. Everyone has read/write access so be sure to promptly remove any files you place on the share.

Time Services

    It is imperative that the time on computer platforms be accurate. To ensure that all of your systems keep accurate time an NTP server (timesrv.net.lcl 172.17.8.18) is available. Be sure that all of your systems are synchronized to the time server directly or through another of your servers.

Security

    You are expected to ensure that your operating systems and application software are protected against viruses and other exploits. As such you must keep your systems fully patched to protect against the propagation of malware. If

    you do not exercise due diligence in protecting your systems and they catch something that negatively affects the operation of the NET.lcl network you may be penalized a letter grade for the laboratory section of the course.

Virus Protection

    The pub share on RTFM also contains a university licensed virus management solution. It is your responsibility to install and update this software on every machine under your control.

Security Scanning

    To protect everyone’s machines and ensure the integrity of the network a Nessus system vulnerability scanner is in use on the NET network. This solution automatically scans every machine on the network and generates a report of any machines with known security vulnerabilities. For your reference, the IP address for the Nessus machine is 172.17.8.16. Information in logs about potential attacks from this source should be disregarded. Spoofing this address in an attempt to break into another machine, even in the context of the C&IT 455 war games, is expressly

    prohibited and will result in an automatic failure of the laboratory.

    If one of your machines should be identified with any vulnerability you will be notified by your TA. Please follow-up with the TA once you have resolved the problem. Failure to resolve the problem by the next system scan will

    result in a letter grade penalty on your final laboratory grade.

Materials and Security

    Absolutely no lab materials (hardware, software, or documentation) are to leave the lab without the expressed permission of the lab instructor. With proper permission, all material is to be properly signed out. Any deviation from the above policy will be considered theft of university property and will be reported immediately to both the Purdue Police Department and Dean of Students office. The student will also be given a failing grade for the

    course as this offense is considered to also be an act of academic dishonesty. It is your responsibility to maintain the lab and its valuable assets.

     4

Safety

    Safety and responsible use of lab equipment/software and other assets is everyone’s top priority. When working on the equipment with the covers off, use a static strap and exercise caution. In general, the shock hazard of a personal computer is extremely low as long as care is taken (i.e. don’t stick a screwdriver into the power supply.) All screws and fasteners removed from equipment should be replaced. Remember, you are the caretaker of the equipment for a brief period of time please ensure that it remains in good condition for those who come after you. Failure to conduct oneself in a safe, responsible manner will result in suspension of lab privileges and receipt of a zero for the lab portion of the course.

Resource Naming

    There has been trouble in the past with duplicate or inappropriate computer and workgroup names. Remember that this is a professional environment, and every person/group is to treat the equipment as you would in a real business scenario. Domains should be named course number-# where # is your group number (e.g. CIT330-5). You may

    name your computers anything you please; just remember to keep names unique and professional.

     5

Laboratory Procedures

    The purpose of the laboratory section of the course is to provide you with hands-on experience with representative technology germane to the course topic.

Laboratory Projects vs. Lecture Material

    Your lab group may be assigned lab projects for which the technology and concepts have not yet been discussed in lecture. It is your responsibility to research the topic sufficiently to successfully meet the requirements of the project. By this time in your C&IT career, your problem solving skills should be maturing. It is expected that you continue to hone these skills on your own in order to be successful in this lab as well as the IT profession in general.

Role of the Laboratory Instructor

    The role of the laboratory instructor is two fold: to explain and clarify the requirements of laboratory assignments and to help guide you in the development of your network analysis skills and problem solving abilities. If you have questions about the assignment or how to approach the assignment please discuss it with your instructor. It is far better to invest time at the beginning of the project to fully understand the assignment rather than having to go back and make extensive changes against the check-off deadline to correct false assumptions.

The laboratory instructor is there to help you develop your knowledge and skills. They are not there to simply and

    immediately solve every problem you experience. Before contacting the laboratory instructor for help make sure

    that you can effectively describe the problem’s symptoms and what you have done to attempt to resolve the problem.

    If you cannot effectively communicate your problem, the laboratory instructor cannot help you solve it. When asking for help, please don’t say “This won’t work.” This is usually met with a curt response of “Did you read the

    instructions?” or “Have you searched (Google) for a solution?” If you want help, ask “This won’t work, we have tried A, B, C, and D. Do you have any suggestions?”

    If you have quantified the problem, searched for a solution but still cannot resolve the issue both the laboratory instructor and professor will gladly work with you to find a solution. However, don’t be surprised if the laboratory instructor answers your question with another question; listen carefully, it’s usually a hint.

Laboratory Groups

    Your success in the lab portion of the course will largely depend upon your ability to successfully work together as a team to complete the laboratory objectives and written reports. To ensure that each group member performs, a peer evaluation will occur at the end of each lab project.

    Occasionally, problems arise with lab groups when certain members do not contribute their fair share. Resolution of such situations is the responsibility of the lab group. If the group is unable to resolve the situation internally, bring the matter to the attention of a course instructor. Professionally present your case, detail the problem along with all corrective action taken thus far, and have a proposal for additional action.

    The course instructor will serve as arbitrator to help you resolve the problems. At the end of the arbitration process a written agreement will be completed that details the responsibilities of each lab member. Failure to live up to the terms of the agreement will result in corrective action ranging from a written warning to removal from the lab group, potentially resulting in a failing grade for the course. Many problems can simply be avoided by creating a similar list of responsibilities prior to beginning work on the lab rather than waiting for a problem to occur.

Suggested Laboratory Project Approach

    It is suggested that the following overall approach to lab project organization and process be used:

    1. Read the project objectives before turning on the first piece of equipment

    2. Formulate an overall plan or direction

    3. Assign responsibilities and deadlines

    4. Refer to the Laboratory Project Assignment section of this document for helpful information on

    successfully completing the laboratory projects. The answers to many commonly asked questions are

    located there.

     6

5. If you should get “stuck” at any point:

    a. Articulate the problem clearly

    b. Document knowns and unknowns

    c. Verify knowns and pursue unknowns

    d. Document each step and procedure

    e. Define alternative approaches

    f. Question your assumptions

     7

Project Reporting

    All laboratory grades are assigned on a per group basis. Each member of the laboratory group receives the same grade, less any attendance penalties or peer evaluation (more on this below). Each project will be documented through a final report and a series of weekly status memorandums with project plan updates. Only one copy of any item is required per lab group.

Technical Progress Status Reports

A Technical Progress Status report (TPS Report) is due at the beginning of each laboratory period, including the first

    week of a new laboratory project. At a minimum the report in Microsoft Word Memo format should contain the

    following information:

    ; What has been accomplished

    ; What is currently under development

    ; What, if anything, might be causing problems

    ; A plan to complete the project by the due date (updated to reflect current status each week)

    Microsoft Project (available on every PC in the SOT labs) is required to document the

    timeframe in which you plan to complete the project

    ; A Gantt Chart including the critical path/task predessesors, logical task grouping, assignment

    of tasks to personnel and resources, and task beginning/completion dates.

    The objective of the TPS report is to reinforce planning and project management skills. You will not be evaluated on how closely you follow your original project plan or how much your project plan changes from week to week, but rather on how effectively you communicate your current project status and plan to complete the project on time. Although the information in the TPS report can vary, it is a formal document and must meet the course standards for typewritten assignments: If a TPS report has excessive grammatical or spelling errors it will be returned for re-submission per the course syllabus. Failure to turn in any required TPS report will result in a 0 for the TPS

    report section of the documentation portion of the current project.

Final Project Reports

    The basic purpose of all technical project reports is to report the results of the project to the reader. Project reports are usually written at the conclusion of a project and serve as the final chapter in a project’s lifeline. A project report should tell the overall story of the project: it's beginnings, the techniques and procedures used during the course of the project, the conclusions or findings of the project, and any recommendations for others who may follow up on the project. The project report serves as an epilogue to the project and a starting point for others who may wish to re-create the project or perform a follow-on project. These reports are due by 4:30 p.m. in the C&IT main office

    (Knoy 255) on the due date listed on the attached course calendar. Late work will result in 50% penalty for the documentation portion of the project grade.

Due to the size of final project reports it is critical that they be bound to ensure that no pages are lost. Failure to

    bind your report will result in a one letter grade penalty on the final laboratory activity grade.

Grammar and Style

    Project reports are formal documents; therefore they should conform to all rules of formal writing such as proper spelling and correct grammar, including but not limited to, prepositions at the end of sentences. Additionally, “Setup” is a noun and the phrase “set up” is an action, use them properly e.g. the setup was four computers with 2K installed as opposed to we set up the network. Failure to write a professional document free of spelling and grammar errors leads the reader to question the quality of the work performed and the validity of the conclusions drawn.

    Information technology project reports typically involve many technical issues that may be difficult to describe in prose. The author should select the best means of communicating the information to the reader: prose, tables, graphs, or figures. If tables, graphs, or figures are used, they should be clearly labeled with a number. Per the APA standard Figure labels should be located directly beneath the figure and table labels should be located directly above the table. The figure number must then be referenced from a point in the body of the report where the information in the figure is relevant. Whenever possible, the figure must be located on the same page as the reference to assist the reader in keeping their place as they read the report. If the figure will not fit on the same page as the reference, it should be a page adjacent to the referring page.
