    What Is A Safe Linux Password?


    Your initial password, and subsequent resets made by a system administrator, will be a combination of your Dartmouth ID number and a random set of characters that will be emailed to you. You should change your password to one of your own choosing as soon as you are able to log in, using the passwd command at the shell prompt.

    What is Linux?


    Linux is the operating system of choice for multi-user, multitasking, networked, and high-performance computer applications. At Dartmouth, Linux runs most of the machines that provide core services, and all of the Research Computing compute servers run Linux.

    Compilers on 64-bit and 32-bit Research Computing Systems


    A 64-bit computer can handle more computations, memory, and I/O than a 32-bit computer. To take advantage of this additional power, software must be built with 64-bit compilers. The 64-bit computer can run 32-bit applications, but running them in 32-bit mode doesn't use all the expanded capabilities of the 64-bit computer. However, software built to use a 64-bit computer cannot run on a 32-bit computer.

    Accounts for Researchers


    A research computing account consists of an account on the central file server (AFS) and login privileges on one or more Linux computer 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.

    Applying for a Research Account

    RStor - Central Data Storage for Researchers


    RStor is Research Computing's data storage offering. It is available to anyone in the Dartmouth community. RStor is based on the OpenAFS distributed filesystem which provides secure network file storage at relatively low cost. RStor is frequently used to share files across the Internet because it has strong authentication and flexible access control. This can be especially useful to researchers when they either need off campus access themselves or the ability to share data with non-Dartmouth collaborators.

    How Do I Store Research Data Or Files?


    Where Do I Store My Data?

    Researchers have access to RStor for data storage. See RStor - Central Data Storage for Researchers.

    How Do I Restore My Research Data or Files from RStor?

    To restore your data or files, email [email protected].

    Using klog to Obtain AFS Credentials


    Even if a Linux system is not set up with usernames or UIDs matching the AFS user database, you can still use all the features of AFS.

    Integrating AFS Authentication with Local Login


    The explicit klog step can be omitted if the system is configured to obtain AFS credentials as part of the standard login process. To do this, the usernames on your local system must match the usernames defined in the AFS user databases.
