IT Standards
Overview
This reference document describes the computing software and hardware in use by OIT at Princeton and, as appropriate, links to additional related information. Standards fall under the following four headings:
Computer Hardware and Software Standards
Computer Hardware
The University's IT environment contains of a large number of computers, almost all of which are interconnected by the Campus Network. The University primarily uses and recommends particular models from only a small number of vendors as described below.Central Systems
In the computing center at 87 Prospect Avenue, the University has a large number of Sun and Dell computers. A smaller number of Apple and IBM computers serve special requirements.Distributed Systems
The University encourages a common platform for electronic communications and core applications through several computer acquisition programs: DeSC, Faculty Computer Program and the Student Computer Initiative.
The Desktop Systems Council (DeSC) reviews and defines the standard administrative computer. The DeSC standard also defines the minimum system and application software to be present on the machine. For more information, see Desktop Computing Infrastructure.
The Faculty Computer Program (FCP) supports the acquisition of desktop technology for full and associate professors and other select members of the faculty. The refresh cycle is a new computer every four years. Eligible faculty have a choice between an Intel-based desktop computer, an Intel-based laptop computer, a Macintosh desktop computer and a Macintosh laptop computer. For more information, see Desktop Computing Infrastructure.
The Student Computing Initiative (SCI) provides Princeton students with aggressively priced, highly capable computers to facilitate academic work. The program is open to all Princeton students with special pricing available to incoming first-year undergraduates, incoming Ph.D. candidates and other special groups. These computers are pre-configured to work well within the University environment. For more information, see Desktop Computing Infrastructure.
The University also provide computing clusters (see the clusters description) as a standard access point for students who need out of dormitory access. These machines have minimum hardware requirements and a standard set of software. For more information, see Desktop Computing Infrastructure.
Computer Software
Central Systems
Central OIT systems run vendor-supported operating systems with appropriate software fixes applied. Not all systems are running the absolutely latest versions.
The University participates in campus-wide site licenses for the delivery of software across many of the computing platforms. The licenses page lists University site licenses for multimedia, mathematical and statistics packages as well as whole suites of software. The Help Desk Software download page explains how to gain access to such software.
The Sun compiler software is installed on the Solaris systems that provide login service.The Linux systems that provide login service have the full Red Hat installation.Distributed Systems
The distributed systems managed by OIT run vendor-supported operating systems with appropriate software fixes applied. Not all systems are running the absolutely latest versions.
Available software at Princeton is described on the Help Desk Software download page.
Services
OIT systems provide a wide variety of network based services for the various computing platforms at the University, including login servers (for Solaris and Linux), file storage for any platform which can use Windows file or NFS file systems, directory services, IMAP-based and Exchange E-mail services, web services, and database services.
Unix and Linux Services
OIT provides authentication services (LDAP and NIS) to the campus. LDAP directory services are available on Unix and Linux. OIT provides NFS, SMB and FTP file services. The login servers provide SSH access.PC Services
OIT provides Active Directory authentication services. LDAP directory services are available on campus Windows machines. The common home directory is available on computing cluster machines at login. It is mountable from any machine in the Princeton domain.Macintosh Services
OIT cluster Macintoshes running OS X use LDAP authentication. The common home directory is available on computing cluster machines at login.E-mail Services
All members of the campus community are permitted to send and receive electronic mail. OIT strongly favors IMAP as the approach. A Help Desk document describes current E-mail standards as well as the authentication required in sending e-mail.Web Services
The University offers a wide variety of tools to help faculty, staff and students build data-driven web sites in support of the hundreds of individual campus applications that involve web access to data.Database Services
The University provides centralized Oracle support for administrative databases.
Network Standards
The campus-wide Ethernet is available in all academic and administrative buildings as well as dormitories and the Graduate College. The Networking Standards document describes the campus telecommunications infrastructure in more detail. This reference document adds only those standards associated with the service.International Standards
Over time, the Internet Engineering Task Force (IETF) has defined most of the computer-to-computer
standards in use today. These standards are described in numbered Requests
for Comments (e.g., RFC 821). Determine whether a new program will be usable
in the University environment sometimes requires that we ask: “Does
it conform to RFC xxx?”
The following table provides references for the standards to which University systems conform. The table uses Request for Comment (RFC) numbers.
