given space in a directory to keep his or her files. This directory will be used by many other tourists, so each must use his or her login name as the first name of each file he or she creates. We do not have much disk space available, so please do not create very many files or very large files. It you have an application for a large amount of data, discuss it with your advisor.
9. The MIT ITS systems have no file protection, hence it is incumbent on all users to exercise great care when exploring the file system. A tourist should not delete or modify the system files or files belonging to other people.
10. Tourists should not disturb other users of the machine while they are working, or engage in any activity which interferes with other users of the machine or with the operation of the machine. It requires no great cleverness to find ways to crash the machine. It is each user's responsibility to make sure that he does not. Some lab members do not like to receive unnecessary messages and consider them an annoyance. To make sure you do not annoy any one, don't send a message to another user unless he has expressed a willingness to receive one.
11. Because mailing lists can affect the allocation of disk space and processor time in ways that are currently not well -understood, tourists should not create or modify mailing lists unless given the ok to do so by a lab member. Modifying mailing lists safely is harder than it looks; an innocent- looking change can cripple the mail system.
12. A tourist account does not imply that the tourist has free access to the laboratory premises. If a tourist wishes to visit the laboratory, he or she should coordinate the visit with his or her advisor.
13. Any use of the MIT ITS machines for personal gain, profit making enterprise, or political purposes is not a legitimate use of the Laboratories' computer resources.
14. These specific statements of policy give a minimum of how a tourist ought to behave to be a responsible user on the MIT ITS system. They are not a complete list of all the ways tourists should or should not behave. Just because some particular anti-social behavior is not listed does not mean that it is acceptable. What a tourist should do is cultivate a good attitude: make a positive effort to anticipate and avoid actions that would interfere with other users. If you cannot tell whether a certain course of action can interfere with any one, find out from someone else before trying it.
15. Unfortunately the ITS systems do not have complete on-line documentation. The INFO system provides access to most of the existing documentation. ;t will be very useful for us if you suggest improvements, or write additional documentation for poorly documented parts of the system. However, please do not install Such documentation without first submitting it to your advisor and getting his or her approval.
