Introduction

For the purposes of this policy, a user is any person using computer resources; Computer Operations is the organization that supports academic computing in SEAS; A system manager is usually a graduate student hired by Computer Operations who is acting in an official capacity as a staff member. This same person may be considered a system manager during part of the day and a user during other parts of the day.
The terminology used in this policy tends to reflect the UNIX operating system, which is used on the majority of computers in the Lyle School of Engineering. However, these polices are applicable to all other computational platforms.

Computer Operations will not normally monitor individual usage of any computational facility. However, Computer Operations reserves the right to monitor and record the usage of all facilities for which it is responsible. If threatening or abusive behavior is being investigated, Computer Operations reserves the right to use information gained in this way in disciplinary or criminal proceedings.
In general, a user of SEAS computer facilities is expected to follow the following guidelines.

General Use

Many resources, such as file space, CPU cycles, printer queues, batch queues, login sessions, and software licenses, are shared by all users. No user should monopolize these shared resources.

Account Management

An account is assigned to an individual, and must not be used by others without explicit permission from Computer Operations. The individual user is ultimately responsible for the proper use of their account, including proper password protection.

Access to Files

Files owned by individual accounts or group members are to be considered as private, whether or not they are accessible by other users. The ability to read a file does not automatically give you permission to read that file. Files belonging to individuals are to be considered private property and should be treated accordingly. Under no circumstances should you alter a file that does not belong to you. In the same sense the ability to alter a file does not give you the right to alter a file.

Disk Space

Use as little file space as practical. Make use of all available means for compressing and archiving files. Deletion of old files, especially files that can be quickly recreated, such as executable and compiler intermediate files .o's is strongly encouraged.
Disk files not related to SEAS's missions and which consume large amounts of space are subject to removal. When users exceed their disk allocation, they will be notified via email by the system. The message will indicate disk usage at the time disk accounting was performed, and the user's disk space allocation limit. However if the disk allocation is exceeded for an extended period, the account may be disabled. This way one may temporarily use a larger amount of disk space. The general guideline is that disk space used for unrelated and personal interest work should be less than 10 per cent of the user's total disk usage.

Temporary Storage

Files and directories may be stored in /usr/tmp for short periods of time, although they are subject to removal without notification. If your program requires the usage of temporary storage, it is suggested that you use the /usr/tmp area. Storing files anywhere else, besides your home directory, or project shared areas is not allowed without prior authorization.

CPU Usage

Unix provides many useful ways to manage background jobs and users are encouraged to take advantage of these features. You must, however, be considerate. If you leave a large background job running, you are responsible for it and all the cpu time it uses. Unattended background jobs may be killed at any time by the System Manager. Frequent abusers may have priority limits imposed.
In general, terminate all background jobs before logging out. Long running, non-interactive jobs should be started with a lower than normal priority via the nice command.

Multiple logins

While UNIX provides for the ability to login several times to one machine, it is expected that a user will not tie up resources with multiple, unused login sessions.

Restricted Use Software

Relinquish licensed software, such as FrameMaker or ProEngineer, when you no longer are using the license.

Workstation consoles

Respect the resources of workstations located in public labs. Do not login to such a workstation and run programs that would interfere with use of that workstation by others currently using it.

Non-academic use

Do not make use of University computing facilities for any activity that is commercial in nature. Commercial activities include: consulting, developing software for sale, and in general, any activity for which you are paid from non-University funds and is not part of the Universities academic mission.
The license agreements for some pieces of software may specifically restrict the software to academic use. It is a violation of this policy to use any software inconsistent with its license agreement. If you are in doubt of the status of a particular piece of software please check with computer operations.

Email

Mail should only be used to send messages to people you know or who need to know something from you. Do not use mail to send large, useless files to random users or generally annoy people with unsolicited messages. Sending mail as another user (either real or imagined) is not permitted and is considered a serious offense.
The United States Government as part of the E.C.P.A., Electronic Communications Privacy Act., includes electronic mail (email) in the same category as messages delivered by the United States Postal Service. This means that tampering with email, interfering with the delivery of email, and the use of email for criminal purposes may be felony offenses.

Security

In general, the staff allows the users great freedom in use of the facilities. However, there are certain kinds of threatening or damaging behavior against which the staff will take action. For example: owning or using burglar's tools, worms, viruses, or trojan horses.
A user who feels that he or she has legitimate reason to experiment with security-related aspects of the computer facilities should discuss the project with the Computer Operations manager before embarking on the experiment. This will help prevent a perhaps embarrassing situation for the student.

These systems are for the use of authorized users only. Individuals using this computer system without authority, or in excess of their authority, are subject to having all of their activities on this system monitored and recorded by system personnel.

In the course of monitoring individuals improperly using this system, or in the course of system maintenance, the activities of authorized users may also be monitored.

Anyone using this system expressly consents to such monitoring and is advised that if such monitoring reveals possible evidence of criminal activity, system personnel may provide the evidence of such monitoring to law enforcement officials.

Non General-Use Computing Facilities

Research Machines
Not all the computer facilities in SEAS are public resources. Users found using non-public facilities will be summarily logged-off those resources.

Fileservers
Some machines are designated as "file servers", and carry login messages asking users to not use these machines for login purposes or indicating restricted access. Do not attempt to login or otherwise access these resources.

Faculty and/or Staff machines
Workstations on faculty and staff desks should not be used without the specific permission of the faculty or staff whom those machines belong.

Software Piracy

Because this is an educational environment, computer systems are generally open to perusal and investigation by users. This access must not be abused either by attempting to harm the systems, or by stealing copyrighted or licensed software.

System Files

System-level files (not owned by individuals) may be used and viewed for educational purposes if their access permissions so allow. The same standards of intellectual honesty and plagiarism apply to software as to other forms of published work. Treat system software is if it were a library you were browsing. Acknowledge borrowing code, algorithms, or data structures from the work of other people.

Application Software

Most application files are part of copyrighted or licensed software, and therefore you should not make your own copies of these files, in whole or in part, except as needed as part of an educational exercise. Removing copies of copyrighted software from the system on which it is licensed may be a violation of the copyright or license.

Computer software protected by copyright is not to be copied from, into, or by using campus computing facilities, except as permitted by law or by the contract with the owner of the copyright. This means that such computer and microcomputer software may only be copied in order to make back-up copies, if permitted by the copyright owner. The number of copies and distribution of the copies may not be done in such a way that the number of simultaneous users exceeds the number of original copies purchased or licensed. Under Texas Law, making your own copies of software having a restricted use license is theft.

Explicit permission must be obtained before access to licensed sources, unix, suprem3, etc will be granted. People making use of these sources may have to fill out a non-disclosure agreement with the appropriate company.

Printers

There are several printers located throughout the Engineering School. Users should also be aware that hard copy output devices are expensive to maintain and that wasteful usage of such devices must be avoided. Printer quotas have been established to discourage unreasonable usage.

Facility/Laboratory/Terminal Area Use

Facilities are often available on an un-monitored basis. It is the responsibility of every user to act in such a manner as to not cause damage to the physical equipment. Eating, drinking and smoking are not allowed in any of the terminal rooms or computer labs . The University currently has a policy prohibiting smoking inside buildings except in designated areas.

Accidental damage, or damage caused by other parties, should be reported to computer Operations as soon as possible so that corrective action can be taken.

College facilities are paid for and operated in part with student money. Please help take care of them! Please bring problems to our attention.

Internet Usage

Excerpted from the NSFNET General Use Document:

"The purpose of the NSFNET is to advance education, research and public service by assisting in the exchange of information among research and educational institutions by means of high-speed data communication techniques and to assist those institutions in gaining access to scientific and educational resources. The network will support collaborative instruction, research and public service; facilitate access to regional, national and international networks and hence to such resources as supercomputer centers; and generally support the education and research mission of the members.

  • Use which is consistent with the purposes above is acceptable.
  • Activities in direct support of acceptable use are also acceptable, such as administrative communications, which support the infrastructure needed for education and research.
  • Use by for-profit organizations for collaborative activities with education and research institutions is acceptable.
  • Communications which violate state, federal or international laws are not acceptable.
  • Activities designed to interfere with the ability of other users to make effective use of the network are not acceptable."

Penalties

A person in violation of this policy may be subject to administrative action, with a penalty of a fine, restitution for services used, or loss of computer privileges. Some actions covered by this policy are also covered by University regulations or all-University policies, the violation of which could lead to academic judicial proceedings. Some actions covered by this policy are also covered by City, State, or Federal law, the violation of which could lead to civil or criminal prosecution. Violation of some of these polices may cause you to lose your access to some or all of our computational facilities. Loss of your account or printer access does not eliminate any responsibility for completing course work or research.

Violations of these policies will be dealt with in the same manner as violations of other university policies and may result in disciplinary review. In such a review, the full range of disciplinary sanctions is available including the loss of computer use privileges, dismissal from the University, and legal action. Violations of some of the above policies may constitute a criminal offense.
