Accounts: As part of Penn's computer system, cattell usernames must be Pennnet IDS. People must get a PennNet ID before they can open their account.
Department faculty and staff, lecturers, postdocs, graduate students, and paid research staff can get accounts on cattell.
Volunteer researchers and guests are eligible for an account only if they have computing needs beyond email, news or web browsing, or if they cannot conveniently get or use another email account.
To request an account complete the form provided in the business office, which also contains instructions.
Computers and printers in Lab Building B3 and A2
The computers in B3 are for graduate students and postdocs. Occasional brief use by faculty is permitted. Undergraduates are not allowed to use these computers. Within the lab building, the computers in room A2 have been set aside from undergraduates and should not be used by others except in emergencies.
NOBODY except "manager" (Vince Hurtubise, Sherry Michael, or those working for them) is to install programs on these computers.
The doors to these rooms are to be kept closed and locked.
Printing is free, but the printer is not to be used instead of a copier. Routine printing of all email is not allowed.
Students who want TCP/IP numbers will have to pay for them.
Quotas and incoming mail
Each account on Cattell has a quota for storage. If the quota is exceeded, you will see a warning when you log in. If you do not use Cattell much, please log in to check once in a while. You do not get email when you go over quota, just a warning when you log in. If your quota is exceed for too long, you cannot store anything.
You can request a quota increase by sending mail to manager. Cattell is not a good place to store all your email, especially when it consists of many encoded attachments. Discuss with manager how to make periodic back-ups on your own.
You can keep your mail on cattell if you can manage to keep your disk needs below 50MB. Most people will need less than that. Those with special needs, such as data storage or a class in which students submit assignments as attachments, can ask for more.
Incoming mail is stored in a "mailbox" until you read it. (Actually the file is called /var/mail/username.) Depending on how you read it, you may delete it, or move it to some file in your home directory (the one with the quota). Some mail reading programs move the mail automatically.
Do not let your mail accumulate in your mailbox for long periods. If your mailbox reaches 2MB in size, you will get a message asking you to reduce its size. When it reaches 3MB, you will get another message giving you 48 hours to reduce it. When it reaches 5MB, you will asked to reduce it within 24 hours, at which point it will be moved to another location, where it will be kept for one week before being deleted.
Aliases on cattell
Several aliases are available - academic, faculty, gg (graduate group), emeriti, staff, business, grad, etc. These are not to be used for material that could be posted to the newsgroup upenn.psych.general. Everyone should read this newsgroup and assume that everyone else reads it. A descriptive header on a message will allow readers to determine whether or not to read a posting.
