Overall System Status:
A research computing account consists of an account on the central file server (AFS) and login privileges on one or more Linux compute servers that all share the same AFS accounts for user home directories. AFS accounts are available to any member of the Dartmouth community. Users may also access the AFS file servers from their own personal workstations. Sponsored (non-DND) accounts can be created in special cases.
To request an account on:
Your account will be created within two business days. You will receive an e-mail message with the details of the account that has been created, including the login and initial password, the computers where the account has been activated, and how to get help. Accounts for faculty and staff are initially set up with disk space quotas of 20 GB. However, research quotas can be increased according to needs (see RStor ) and on a hardware cost-recovery basis. All accounts on central systems are backed up on a regular schedule as a protection against accidental deletion of files. However, backup files are not kept indefinitely. Please consult the backup schedule for details.
Connecting to a UNIX system requires you to log in to the system. The login process involves entering your username (also called login name) and password. If you have an account on the Research Computing systems, your username (and password) will be the same on all of the systems.
You will be assigned a username that consists of the first letter of your first name and your last name, up to a maximum of eight characters. For example, John Smith would have the username jsmith.
If you have forgotten your username or password on the Research Computing systems, you can request a password reset by sending an e-mail from your Dartmouth e-mail account to firstname.lastname@example.org asking to have your username or password sent to you.
Disk quotas are imposed on all central UNIX systems to divide up the disk resources fairly, and to protect the systems against runaway programs filling up the disks and preventing other people from doing their work. The quotas are flexible and can be changed upon request, especially for special short-term projects. If the disk quotas seem restrictive, remember that this is guaranteed disk, backed up nightly, and maintained by full-time staff. The effective cost is therefore much higher than a disk you can purchase for your own use.
Each user is assigned a disk quota for their shared space (AFS). They may also be assigned additional space local to particular computers (for data files or scratch space) or additional AFS volumes for special projects. The command to check your quota on any system is quota [directory].
By default, the user's home quota is reported. If a directory is named, the quota relevant to that directory (if any) is reported. If local disk quotas are in use on the system, all quotas assigned to the user are reported.
If you think you are out of disk space, follow the steps below.
The most common reason users cannot log in is that they have forgotten their password or their user name. To fix the problem you are having logging in to your account, follow the steps below.
To request a password reset, you must send e-mail from your Dartmouth email account to email@example.com.
E-mail for a password reset request must be sent from a Dartmouth e-mail account (i.e. do not send the request from Gmail, Hotmail, Yahoo, etc.). If you send a password reset request from a non-Dartmouth e-mail account, you will be instructed to resend the request from your Dartmouth account.
When your password reset has been completed, you will be notified of the new password through an e-mail message.
