The following policies of the Department of Mathematics and Computer
Science supplement Grinnell's Academic Computer Use Policies.
MathLAN policies apply only to this department's network. When MathLAN
equipment is used to access outside equipment, either in the College or
over the Internet, then all ITS policies apply as well.
Violators of these policies may be prosecuted following the procedures
outlined by ITS regulations or have their accounts
We distinguish four categories of computer use. In descending priority,
- academic work for courses within the department;
- other scholarly work sponsored by faculty members in the
- academic work for courses outside the department and other scholarly
work sponsored by faculty members outside the department; and
- other uses, consistent with ITS's statement on the proper use of
When the demand for equipment in the laboratory or computer-equipped
classroom exceeds what is available, users engaged in activities of lower
priority must yield to those requiring the equipment for projects with
When a class has reserved the laboratory or computer-equipped classroom,
only members of that class are permitted to use the reserved room during
class time. Students not in the class may, upon consultation with the
faculty member running the class, receive permission to use the reserved
Since MathLAN is a network, a user has the capability of running processes
on several workstations at once. It is inappropriate for one user to
interfere with the processing of others who may be running jobs of equal or
higher priority. Similarly, it is inappropriate for a user to run jobs
that generate so many messages over the network as to degrade processing
for other users. It is also inappropriate to remote log-in or telnet to a
machine on which another member of the community is currently working.
The workstations on faculty desks are for the use of those faculty members.
Any student who runs processes on a faculty workstation without permission
from that faculty member or a MathLAN administrator may have his or her
The Grinnell College Academic Computer Use Policies discuss sharing of
accounts in sections III.A.1 and III.A.2:
- No person may use, or attempt to use, any computer accounts other
than his/her own assigned account. The negligence or naivete of another
user in revealing an account name and password does not confer
authorization to use the account.
- An account owner may not lend his/her account(s) to another user.
The Department of Mathematics and Computer Science realizes that you may
share accounts when working together on a laboratory, and
permits such use. However, that is the limit of sharing. In particular,
no student may use an account without the owner of that account present.
The department does not forbid the use of Internet Relay Chat (IRC).
However, such use must not violate the guidelines described in Grinnell's
Academic Computer Use Policies. Furthermore, the department disallows
the use of chat robots and proxy servers without prior
permission of a MathLAN administrator. Such programs often result in
decreased system or network performance and thereby directly affect other
users, both local and remote.
According to the above policies, games running on MathLAN and played by
individuals fall within priority 4, unless game programs are specifically
assigned as part of a course or are part of project under faculty
sponsorship. Thus, a game may be run on MathLAN provided that (1) others
are not waiting for workstations for academic purposes, (2) the running of
the game will not generate processes on machines used by others, and (3)
the game does not significantly interfere with the message load over the
Since MUDs and other games involving the Internet utilize the all-campus
router, such games are explicitly prohibited by ITS policy.
Students may not use the projection systems in the Department's classrooms
and labs to show movies, except for academic purposes and with the express
permission of the Department.
In addition to the reasons given above, an account may be deactivated
by a MathLAN administrator if the administrator deems that the
account is being used inappropriately or has suspicious activity.
In addition, any account inactive for a year or more may be deactivated.
The MathLAN administrator will maintain the files of any deactivated
account, either on disk or on backup tape, until the owner of that account
graduates or otherwise leaves the Grinnell community.
At the time of an account's deactivation, the accounts owner will be
contacted through his or her standard Grinnell e-mail account. A
student's account may be reactivated upon request.
