Physics and Astronomy Computing Support Policy

Supported Systems

Introduction

The installation and maintenance of specific hardware and software for UNIX, Linux and Windows systems is supported. No support will be provided for any systems that fall outside the following categories. Support for all stand-alone Windows, Linux, Macintosh and other systems is provided by the user. Strict computer security limits apply to connecting any computers to the Physics network.

For help with personal laptops we recommend either contacting University's 1-HELP computer support line or visiting the Tech Stop at Coffman Union.

Linux

We support systems running our centrally administered Linux distribution.

Currently the supported Linux installation is Scientific Linux. Systems that require the use of special hardware drivers are generally not supported.

Linux systems must be configured with a dedicated disk for the operating system. Home directories are accessed over the network by NFS from our main file server. Bulk research data is accommodated on specific storage servers, separate from home directories.

Root access is not available for end users on these systems. Where necessary, certain administrative functions will be made available using the “sudo” command.

Windows

PC systems running our customized installation of Windows 7 are supported. The systems are configured with their hard drive dedicated for the system and applications; user data must be stored on the network file server. Computers are connected to the university Active Directory system, and use university username and password for login. The OS is installed using disk-imaging (Ghost) which requires specific hardware for compatibility. Systems not meeting the hardware requirement cannot be supported.

Administrator-level access for software installation and other system changes is not available for end-users on these systems, other than by special arrangement for computers used in specific faculty offices or research labs.

Software Support

Managed Systems

All departmentally managed systems are provided with a wide range of commonly used software. These include compliers, Tex/LaTex web browsers, Microsoft Office products and the like. Applications on maintained systems are supported to the extent that they are installed and operate correctly. Assistance on usage of these applications is not available within the department.

Software

Several software packages are distributed for users to install on their own self-managed systems. Details of available software is provided on the web site.

Backups

Supported Unix and Windows home directories on the department's managed systems are backed up every night.

Security

All users must meet both University and Departmental security standards which can be found at http://www1.umn.edu/oit/security/ and in these pages.
