[Here is the draft policy statement from another OSU organization (that I may have confused with CIS). The policy seems very resonable. My impression from email conversions with ACS users is that many of them don't know about the policy; perhaps because it has not been finalized. It would be nice if users participated in the policy's formluation (and application). ASC users can see the newest version of the policy by typing "man magnus" at the Unix prompt. - Carl] 7 March 1991 magnus(1) DRAFT NAME magnus - a brief description of MAGNUS DESCRIPTION The MAGNUS system is a cluster of several Unix systems run by Academic Computing Services (ACS) for use by members of the Ohio State University community. The main user systems in the cluster are two DECsystem 5500's running the Ultrix operating system. There is a separate system for Usenet news. The main processors have 64 megabytes of main memory, 1 gigabyte of private system disk storage, run at 28 million instructions per second, and are connected by a private shared ethernet communications link. The cluster has 4 gigabytes (one gigabyte is 1000 megabytes) of user disk space and 1 gigabyte of news storage disk space. The main processors are connected to SONNET for network access and also have 64 serial links connected to the network switch for tele- phone access. When you log in to MAGNUS, your session may end up on either of the main processors. However, the environment is set up so that all of your files and resources are available no matter where your session or program is actually running. You have a choice of three user interfaces when using MAGNUS. The first is the default menu interface for VT100-compatible termi- nals and microcomputer terminal emulators. The second is the standard Unix shell command line interface. The third is a VMS command line interface. MAGNUS USAGE GUIDELINES The MAGNUS system is intended to provide access to electronic mail, information services, and text-oriented Unix computing. It also serves as a Unix training resource. The system has a full complement of Unix software, including several compilers. These compilers are intended for use in textual programming, program development and training applications. The MAGNUS system was not designed to support intensive numeric computational processing. That service is available on the IBM 3081D MVS system which has a wide variety of numeric software packages. See a mainframe con- sultant in Baker Systems Engineering, Room 508 for further infor- mation on the MVS system. MAGNUS resources are intended for fair and distributed use among a large number of authenticated users with logon accounts. Usage should be consistent with the university's instruction, research, and service missions.In the event your usage patterns interfere with other users, the system administrators may ask you to help assure a fair distribution of resources by running your processes at a lower priority or by avoiding practices which penalize other users. If this does not resolve the difficulty, User Services representatives will contact you to determine how your needs can be met consistent with our goal of meeting all other customers' needs. In the event that you are not logged in or cannot be reached when your processes are interfering with fair use by MAGNUS - The Ohio State University 1 magnus(1) 7 March 1991 DRAFT others, system administrators may lower your processes' priori- ties or terminate your processes. You will be sent an electronic mail message with full details. Examples of inappropriate activity would be running a server program which allows use of system resources without login authentication or maintaining a serial or network connection open with no activity for over an hour. Unauthorized computer use may have serious consequences that could result in suspension, dismissal, and/or criminal penalties. You are cautioned to protect your password and computer files. Your computer account is provided for your use and your use only. You may not give your password to any other person. You may not use another person's account even if they give you their pass- word. If system administrators find indications that your account has been compromised or is subject to unauthorized use, the account will be immediately disabled for your protection. User Service personnel will then contact you as quickly as possi- ble to resolve the situation. ON-LINE ASSISTANCE MAGNUS systems administrators are available for on-line assis- tance and consultation. The hours are 8am to 9pm Monday through Thursday, 8am to 6pm Friday, and 11am to 4pm Saturday and Sunday. You can reach this on-line service by sending mail to "consult". From other systems, send mail to the full address of "consult@magnus.acs.ohio-state.edu". Mail received outside the listed hours will be handled during the next scheduled assistance hours. You may also telephone 292-0886 (on campus, 2-0886) during the listed hours. ON-LINE DOCUMENTATION Most Unix commands, software, file formats, and other items are documented in the Unix on-line reference manual pages. To see the on-line reference manual for an item, use the man command. For example, enter man ls for information about the ls command. USER DISK FILE BACKUPS All new or changed user disk files are backed up to digital audio tape cartridges (DATs) on a daily basis to minimize accidental loss of data. The backups are done near midnight. If you lose a file that you have had at least overnight, send mail to "con- sult". Provide as much information as possible about the file: its name, when you deleted it or noticed it was gone, when you last knew it was on disk, etc. A system administrator will attempt to restore your file and notify you. 2 MAGNUS - The Ohio State University 7 March 1991 magnus(1) DRAFT USER DISK FILE SIZE LIMITS Faculty, Staff, and Graduate Students may use up to 2 megabytes of disk storage by default. This default is called a soft quota. Undergraduate students may use up to 500 kilobytes. Faculty, Staff, and Graduate Students can apply for a higher limit by sending mail to User Services, "custserv@magnus". All users can exceed their limit temporarily. The system will allow you to use up to 2.5 times your default limit for a short period. This larger temporary limit is called a hard quota. Once you have exceeded your soft quota, you will be allowed three more logins to free enough disk storage to get below your limit. You can use the disk usage command, du, and the quota command to monitor and manage your disk use. Send mail to "consult@magnus" if you need assistance or information about your quotas and actual use. SYSTEM TEMPORARY DISK FILES The system uses a temporary file system, /tmp, to store of scratch files and for other short term storage. Files in this file system are removed daily. Temporary files not in active use may be removed at any time to improve system performance. INCOMING MAIL STORAGE New incoming mail messages are stored in a disk area called the system mail spool. This area is shared by all users. Your incom- ing mail is stored in this area so that you can still receive mail even if you are temporarily over your normal disk quota. Mail programs such as elm and Berkeley mail may allow you to leave mail in the system spool files temporarily before moving it into your own disk files. These files in your own disk space are usually called received or mbox . We recommend that you leave only a few mail messages in the system mail spool and that you regularly move your mail into your own disk files. Since the system mail spool is a shared area, if you keep too large an incoming mail spool, you could affect other users. In the event that your system mail spool storage becomes quite large, usually more than 100 messages, depending on size, a system administrator will contact you to help you reduce your system mail spool. If you cannot be contacted, for example if you are on vacation, your incoming messages will be placed in a file, compressed, and moved into your disk space. You will get a new mail message explaining what has happened and how to read the messages. If you have any difficulty, send mail to "consult". MAGNUS SOFTWARE The MAGNUS system runs DEC's ULTRIX Unix operating system. Therefore it has all the software DEC provides with that system. Some of this software is supported by DEC and some is unsup- ported. The on-line reference manual pages for the software, accessed with the man command, give the status for specific MAGNUS - The Ohio State University 3 magnus(1) 7 March 1991 DRAFT programs and commands. Use the command man software for more detailed information. The system also has software added by ACS. Some of this software was developed by ACS, some was obtained from public domain or cooperative Unix user sources, and some has been purchased from software vendor companies. The on-line reference manual pages for the software will identify the source of an item and whether it is supported or unsupported. Software designated as not supported by DEC will not be supported by ACS. Unsupported items will be maintained at low priority. In addition user assistance may not be available for unsupported software.
