Orion Frequently Asked Questions

This material is taken from questions submitted to admin@orion.luc.edu and problems submitted to the Information Technologies Helpdesk (x44444 helpdesk@luc.edu).

Q: I am over my disk quota and I've deleted many files and a lot of email yet the system still reports that I am over quota. What is the problem?

A: Disk usage as reported by the quota command is updated once a night. The numbers are not indicative of current, real-time usage. Try du for actual usage.

Q: My account has had restrictions placed on it for being 'over quota' for about a week now. I believe the problem has been taken care of, as I cleared out all large files last week. Can you please lift the restrictions now?

A: The file system quotas are automatically enforced by AIX, the operating system that Orion is running. Information about the quota for your account can be retrieved by issuing at the Orion shell prompt the command:

this should produce results similar to the following:
Disk quotas for user xxxxxxx (uid xxxxx):
     Filesystem  blocks   quota   limit   grace   files   quota   limit grace
            /u3    5532*   5120    6144    none     179    5120    6144
In this example, the "soft" quota for the account is 5.1 Megabytes and the hard quota is 6.1 Megabytes. These are the standard restrictions on Orion. The "none" under grace shows that AIX has automatically traced the account as having been over the soft quota for over the one week grace period. This is due to the fact that the account currently contains 5.5 MBs which exceeds the soft quota by 400Kbytes. Once the additional 400KBs have been removed from storage on Orion, the operating system will automatically reset the grace period for being over soft quota back to one week.

Q: Why does Orion demand that I change my password so often? Why are Orion's password criteria so complicated?

A: Orion requires you to change your password every six months. Orion does not permit simple dictionary words as passwords because they can be cracked by widely-available brute-force password guessing programs. Apollo, Orion's predecessor, was involved in perhaps the world's most famous computer break-in. Search for "loyola" on this page: http://www.gulker.com/ra/hack/index.html. Orion's security policies are in place to protect the data of all its users.

Q: I forget the password of my account at Orion. How can I restore it? Can you email me a new password?

A: Due to security considerations, we do not send passwords in email. If you are unable to call the Help Desk during the day for help with your password, probably the easiest way to restore it is to fill out an Orion password restoration form. The form should be returned to a Loyola Computer Center and presented along with your Loyola ID.

Q: Every time I try filezilla, I get a message that my password is invalid or my connection just drops. What's up?

A: Your password has expired. Filezilla can't tell you that. Try logging in using putty, you should see a request to change your password.
