The UserLinux Project is developing an effective, streamlined, freely available Linux distribution for businesses of all sizes. The project is not-for-profit with associated services available from a network of commercial service providers.

UserLinux organization will be a not-for-profit organization. The UserLinux product is a GNU/Linux distribution based from Debian GNU/Linux, but streamlined to a smaller set of default applications.

UserLinux will be freely available in both source and ISO formats. UserLinux will be complemented by a worldwide network of (generally for-profit) service providers offering certification, support, and professional services.

UserLinux will offer businesses unrivaled value by providing a strong base of intelligently selected software accompanied by vendor neutral support and certification options.

Security, training, and worker portability issues are greatly reduced through the selection of the prime application for a specific need. There are no licensing fees for software or development tools. Support services are available from a variety of professional service providers, but are never mandatory.

The UserLinux product is a Linux Operating System distribution streamlined to a smaller set of default applications for business use. The UserLinux variants, currently in beta testing, are freely available in both source and CD installation image formats.

UserLinux has four primary configurations:

Enterprise Server:A solid production server featuring Apache, Samba, and Postfix. Great as a web or file server.
Enterprise Desktop:GNOME desktop featuring OpenOffice.
GUI Server:Features a thin Graphical User Interface environment for more convenient local administration. Same core functionality as Enterprise Server.
SOHO Desktop (Small Office/Home Office):A desktop and server in one. A wider range of capabilities to meet the needs of small businesses.

UserLinux will be driven by the not-for-profit UserLinux Organization and backed by a network of for-profit professional service providers. The distribution will be accompanined by available certifications for people, software, and hardware.

Key UserLinux Advantages:

Streamlined:UserLinux is a streamlined distribution with one key application in mind for a given piece of functionality. One web browser, one word processor, one mail client, one web server. This reduces support overhead both for users and for maintaining security.
Standards compliant:UserLinux encourages cooperation with other open source organizations, and values compliance with open standards.
Designed for business:The UserLinux distribution is specially tailored towards the needs of business.
Professional Services:The third party network of UserLinux affiliated commercial Independent Software Vendors (ISVs) allow for choice in professional services and custom application design options. The separation between the UserLinux organization and the ISVs is a win-win proposition allowing both the support advantages of a service provider network and the neutrality advantages of an operating system not tied to a single company.
Flexible:While each UserLinux configuration is designed to support common functionality as shipped, the systems are also open for expansion beyond the standard UserLinux set.
Disclosure:As a not-for-profit organization working with software developed in the open, the UserLinux organization as well as the development process for the UserLinux distribution are in the open. Critical system updates are clearly and promptly announced so systems remain properly secured.
Lack of lock-in:There are no licensing fees for the UserLinux distribution or related development tools. Service is available from your choice of service providers, but is never mandatory.
Free to obtain:ISO images and the source code are freely available.
Inexpensive to maintain:The streamlined nature of the UserLinux distribution assures less software to update. There are no per seat charges or OS licenses to be tracked and audited.
Secure:Leveraging from the power of open source, the code used in the UserLinux distribution not only has thousands of hours of development but thousands of hours of peer review.
Certifications:Hardware, software, support and professional certifications will be available. The standards and corresponding tests will be created by UserLinux with third parties performing the testing activities.
Mature Software:UserLinux is directly based from Debian GNU/Linux, a general focus, free Linux distribution in existence for over a decade. Key components of UserLinux, including the highly popular Linux Kernel and Apache web server, are very mature with millions of critical-use installations.

Boston University Linux is based on Fedora Core Linux, but specifically tailored for the BU environment.

Weve added security updates, made modifications to make software work better with the way things are set up here, and added some applications that we think you might like to have.

The server edition of BU Linux provides a modern, stable, and robust server platform suitable for long-term deployment in many roles throughout the university.

Supported Hardware

Currently, only i686-class machines are supported. This includes almost everything from Intels Pentium Pro on. AMD64 and Intel EM64T systems will work fine using their 32-bit mode. Watch for a 64-bit version later this summer.

Specific Notes on Server Applications

Mail Server:

BU Linux 4.5 Server Edition (Zodiac) includes three different choices of Mail Transfer Agent (MTA) for your mail server. Each of these open source servers has its unique strengths, and you can install one or more and use the utility system-switch-mail to choose which is active.

The default is IBMs Postfix, which is designed from scratch to be secure and easily configurable. On a newly-installed BU Linux machine, Postfix is configured to exchange mail on the local machine and to send mail out to other systems, but not receive mail from the network. For this reason, outgoing mail from global BU accounts (those matching valid BU login names and with the proper UID) will appear to come from @bu.edu rather than @hostname.bu.edu. Local users (including system accounts) will retain the hostname, but without reconfiguration, any replies will bounce. Changing the system to accept mail is easy; see the BU Linux web site for details.

For the maximum flexibility and for compatibility with existing configurations (and with existing expertise), we also include the traditional standard Sendmail. And, if you have particular special needs, you may find that the new Exim MTA fits your situation best.

No matter which MTA you choose, please contact us if you need any assistance. With so many options available, the situation can be confusing, and its unfortunately easy for an accidentally misconfigured system to become a target for spam relayers. We have significant expertise at configuring both Postfix and Sendmail in a variety of situations, and will be glad to help.

FTP Server:

This release of BU Linux provides two options for FTP. The first is vsftpd, which is designed to be simple and secure. This is the most appropriate for almost all situations, but if you require more power and flexibility, we also include ProFTPd, which has many more options and a configuration syntax similar to that of the Apache web server.

Please also remember that FTP is an insecure protocol and that any passwords used travel over the network in plain text. For this reason, its best to avoid anything but anonymous FTP. For user-authenticated file transfer, use SSH and SFTP. (SFTP is provided by the OpenSSH server and enabled by default.)

Web Server:

The web server software included in BU Linux is the industry-standard Apache httpd. We also include PHP 4.3 and many other useful tools for building a web server.
If you need to provide authenticated access to web services to BU users, please contact us and we will provide you with our University-standard Weblogin module. This provides a powerful and flexible means of single-signon access control for the BU user community and we want to make it as easy as possible for you to provide this for your users.

Database Server:

BU Linux includes MySQL 4.1 and PostgreSQL 7.4. For less demanding SQL applications, we also provide SQLite 3, which provides simple SQL databases without the management overhead of running a SQL server.
