These policies provide guidelines for use of accounts on the student machine Xenon. Failure to abide by these policies puts the user at risk of having his or her Xenon account disabled or removed. These policies are subject to change without notice.
Under the current policy, account names are not normally changed after the account is opened. Similarly, CS email aliases (used for directing email through @cs.stanford.edu) are normally not changed except with the consent of the owner. There are, however, situations where an account name or CS email alias will be changed or eliminated. This is normally decided on a case-by-case basis by the facilities committee or CSD-CF (depending on the situation). One case where this may happen is when a faculty member has a last name matching an existing account or CS email alias belonging to a student or former student. Also, if an account and/or CS email alias is not currently in use, it is subject to change or elimination.
core - one week (core dump) #* - one week (e.g., emacs autosave files) *~ - one month (e.g., emacs backup files) /tmp/* - 10 hours and at every reboot /var/tmp/* - one week
Please do not use /tmp for storing files. /tmp uses the swap partition which is of limited capacity, and /tmp is cleared on every reboot.
You can use /var/tmp for storing files temporarily. Do not abuse this option. Anyone abusing this option may have his or her account disabled or removed.
