Documentation

• FreeBSD Documentation Project The FreeBSD Documentation Project is a group of people who maintain and write the documentation (such as the Handbook and FAQ) for the FreeBSD project. If you want to help with the documentation project, subscribe to the freebsd-doc@FreeBSD.ORG mailing list and participate.
• FreeBSD Resources for Newbies is a list of resources to help those new to FreeBSD and UNIX® in general. There is also a freebsd-newbies@FreeBSD.ORG mailing list.
• FreeBSD Security How-To FreeBSD is a very secure operating system. Since source code is freely available, the OS is constantly going through the review and audit. While FreeBSD comes very secure OOB (Out-Of-Box), there are many features that can make it more secure for those of you who are "paranoid". This How-To will go over some steps which will help you increase overall security of your machine.
• RELEASE/SNAP finder for FreeBSD FTP servers. A resource that would allow anyone to find a FTP server that contains particular releases and SNAP of FreeBSD. The database is updated daily at 3am Melbourne time (10 hours ahead of UTC).
• The FreeBSD Diary is a collection of how-to entries aimed at UNIX novices. The aim is to provide a set of step-by-step guides to installing and configuring various ports.
• A Comprehensive Guide to FreeBSD - an attempt at a more readable, "book-like" tutorial explaining the FreeBSD Operating System. Intended for people new to both FreeBSD and UNIX. Currently a work in progress.
• FreeBSD How-To's for the Lazy and Hopeless is another somewhat more light-hearted attempt to provide more readable "how-to" style information on setting up and configuring FreeBSD.
• The Linux+FreeBSD mini-HOWTO describes how to use Linux and FreeBSD on the same system. It introduces FreeBSD and discusses how the two operating systems can cooperate, e.g. by sharing swap space.
• Install Preview for FreeBSD 2.2.7 This is a guide illustrating the FreeBSD install program for those new to unix and/or FreeBSD.
• The FreeBSD Developers Handbook
• The FreeBSD Cook Book Ok, you got FreeBSD installed, now what? Here are some suggested solutions to common problems you can implement with the knowledge you now have. This document is styled after the electronics cook books with some recipes for some common types of installations. Each "recipe" has some recommended minimum hardware, specific software to use, and most important the configuration information required to get the system running correctly.
• The FreeBSD Corporate Networker's Guide This Web site serves as a supplement to The FreeBSD Corporate Networker's Guide, with the principal goal of enhancing its usefulness. While books like fictional novels can be used and enjoyed for hundreds of years after initial publication, technical manuals like the Networker's Guide are obsoleted in a few years by changes in the product they are written for.

Applications

• Java™ on FreeBSD This contains information on where to obtain the latest JDK™ for FreeBSD, how to install and run it, and a list of java software that you may find interesting. Please note that the JDK is unsupported on versions of FreeBSD prior to 2.2.
• GNOME on FreeBSD This contains information on where to obtain the latest GNOME for FreeBSD, how to install and run it, latest project news and updates, FAQ covering FreeBSD-specific GNOME issues, application porting guidelines and much more.
• MultiMedia A resource of links to information and software pertaining to the world of multimedia in the UNIX world.
• FreeBSD Ports Collection The FreeBSD Ports Collection provides an easy way to compile and install a wide range of applications with a minimum amount of effort. A list of current ports is available along with a search mechanism to see if a specific application exists in the Ports Collection.
• FreeBSD Ports distfiles survey is a list which checks the Ports Collection for unfetchable distfiles and provides a summary for each port.
• FreshPorts provides the most up-to-date list of ports and port changes. Add your favourite ports to your watch list and receive email notification of any changes.
• Bento is a server which checks the Ports Collection and keeps package building logs and error logs for each port.

Networking

• ALTQ: bandwidth management for applications
• KAME Project, a free IPv6/IPsec stack for BSD
• Point to Point Protocol (PPP)
• Secure MobileIP via IP
• SYSLOG-SECURE: In August 2001 a standard of syslog was made: RFC3164. This to describe some extensions tot syslog to add security. The project I started in 2002 is to adapt RFC3164 to FreeBSD version of syslog, and to add some security extensions. At least syslog-sign. Both libc and syslogd will be modified. And optional some tools to verify/manage the security will made. All help is welcome. Send an email to albert@ons-huis.net for info.

File system

• HFS and HFS Plus in FreeBSD. This project is aimed at integrating HFS support from Darwin into FreeBSD.
• Arla is a free AFS client implementation. The main goal is to make a fully functional client with all capabilities of normal AFS. Other planned and implemented things are all the normal management tools and a server.
• Coda is a distributed filesystem. Among its features are disconnected operation, good security model, server replication and persistent client side caching.
• cryptfs encrypts file names and data pages using Blowfish.
• Elephant: The File System that Never Forgets
• Journaling versus Soft Updates: Asynchronous Meta-data Protection in File Systems
• Mode locking
• Make the namei interface reflexive
• NFS client and server locking
• The Design and Implementation of a DCD Device Driver for Unix
• NTFS Driver for FreeBSD This driver allows Windows® NTFS partitions to be mounted by FreeBSD. Currently NTFS partitions can only be accessed in read-only mode, but plans are in the works for read/write access.
• Rio (RAM I/O): The Rio project is investigating how to implement and use reliable memory. Reliable memory enables dramatic improvements in reliability and performance.
• Soft Updates: A Solution to the Metadata Update Problem in File Systems
• TCFS is a Transparent Cryptographic File System that is a suitable solution to the problem of privacy for distributed filesystem. By a deeper integration between the encryption service and the filesystem, it results in a complete transparency of use to the user applications. Files are stored in encrypted form and are decrypted before they are read. The encryption/decryption process takes place on the client machine and thus the encryption/decryption key never travels on the network.
• Tertiary Disk is a storage system architecture to create large disk storage systems that avoid the disadvantages of custom built disk arrays. The name comes from twin goals: to have the cost per megabyte and capacity of tape libraries and the performance of magnetic disks. We use commodity, off the shelf components to develop a scalable, low cost, terabyte capacity disk system. Our target is to build a complete storage system with about 30-50% extra to the cost of the raw disk. Tertiary Disk uses PCs connected by a switched network to host a large number of disks. Our prototype consists of 20 200MHz PC PCs, which host 370 8GB disks. The PCs are connected through a 100Mbps Ethernet switch.
• Vinum is a logical volume manager modeled after the VERITAS volume manager™. However, it is not a clone of Veritas, and attempts to solve a number of problems more elegantly than Veritas. It also offers features that Veritas does not have.
• The PathConvert project is to develop utilities which make conversion between absolute path name and relative path name. It brings benefits mainly to the users of NFS and WWW.
• WAFS is a simple filesystem designed to act as a logging service for kernel subsystems. Reads and writes are keyed by log-sequence number (LSN). All writes to WAFS are sequential. Kernel subsystems can use this LSN service to enforce write-ahead logging and guarantee consistency.

Kernel, security

• Drawbridge is a firewall package that was developed at Texas A&M University and was designed with a large academic environment in mind. It's greatest strength is the ability to perform high speed packet filtering for a larger number of individual hosts within an intranetwork.
• Kernel Scheduler Entities: A project to enhance the threading support on FreeBSD, using a threading system similar in design to Scheduler Activations.
• Lottery Scheduling Kernel: This work is based on Waldspurger's lottery scheduling algorithm, which implements proportional-share resource management. The primary advantages are that users have strict control over the relative execution rates of their processes, and users are load-insulated from each other, preventing one user from dominating the CPU.
• Working LDAP for FreeBSD
• Symmetric MultiProcessor Support Documentation and other information about taking advantage of multiple processors under FreeBSD.
• A validation suite for testing for kernel memory leaks
• SPY allows you to monitor and/or selectively block syscalls on your system. It could be used either as a safety monitoring device, policy enforcement, or debugging tool.
• TrustedBSD provides a set of trusted operating system extensions to the FreeBSD operating system. This includes features such as fine-grained privileges (capabilities), Access Control Lists, and Mandatory Access Control. These features are being integrated back into the base FreeBSD distribution, as well as being ported to other BSD-derived systems.

Device drivers

• BSD Driver Database Just because you don't have the time to write the driver yourself doesn't mean you can't still help. The idea behind the BSD Driver Database is to help individuals with hardware that needs supporting get in touch with driver developers with the knowledge to write the support for the hardware. This is a list of drivers currently under development that could stand to gain from time or resources you may have to offer.
• busdma and SMPng driver conversion: busdma provides a portable abstraction to the Direct Memory Access (DMA) hardware primitives used by many high performance device drivers. By using this abstraction, device driver authors avoid adding platform-specific DMA management code, improving the portability of drivers between hardware architectures. This page also tracks the progress of drivers towards being SMPng-safe.
• A New Device Framework for FreeBSD
• BSD ATM: implementation of ATM internetworking under 4.4BSD: New computer applications in areas such as multimedia, imaging, and distributed computing demand high levels of performance from computer networks. ATM-based networking solutions provide one possible alternative to meeting these performance needs. However, the complexity of ATM over traditional networks such as Ethernet has proven to be a barrier to its being used. In this paper we present the design and implementation of BSD ATM, a light-weight and efficient ATM software layer for BSD-based operating systems that requires minimal changes to the operating system. BSD ATM can be used both for IP-based networking traffic and for ``native'' ATM traffic.
• High-precision timekeeping with FreeBSD How to create a NTP stratum 1 server with state of the art performance.
• Home Automation with FreeBSD such as appliance controllers, infra-red controllers, automated telephone systems, and more.
• CAM: New SCSI layer for FreeBSD Details about what the new CAM SCSI layer is, and how it works.
• The FreeBSD Token-Ring Project Information, files, patches, and documentation about adding Token Ring support to FreeBSD.
• FreeBSD USB driver development The NetBSD USB stack has been ported to FreeBSD. Together with them we have started developing the drivers for many devices using the USB bus. Have a look on the webpage if you want to join the effort or you want to have a look on the devices that are being supported.
• Setting up PnP (Plug-and-Play) and the AWE64, AWE32, or SB32 soundcards with FreeBSD.

Architecture

• Porting FreeBSD to Alpha systems Contains information on the FreeBSD Alpha port such as the status, mailing list information, the hardware used, and other Alpha projects.
• Porting FreeBSD to IA-64 systems This project is responsible for porting FreeBSD to the IA-64 architecture. Direct any questions specific to this project to the freebsd-ia64@FreeBSD.org mailing list.
• Porting FreeBSD to PowerPC® systems. Contains information on the FreeBSD PPC port, such as mailing list information and so on.
• Porting FreeBSD to SPARC® systems Contains information on the FreeBSD SPARC port including a FAQ, some early boot code, information on SPARC processors and motherboards, and other SPARC projects.
• The SysVR4 Emulation page describes an SysVR4 emulator for FreeBSD. It is currently capable of running (or walking, in some cases) a wide-ish variety of SysV executables taken from Solaris™/x86 2.5.1 and 2.6 systems. I have reason to believe that it will also run SCO UnixWare and SCO OpenServer binaries.
• The OSKit The OSKit is a framework and a set of 31 component libraries oriented to operating systems, together with extensive documentation. By providing in a modular way not only most of the infrastructure "grunge" needed by an OS, but also many higher-level components, the OSKit's goal is to lower the barrier to entry to OS R&D and to lower its costs. The OSKit makes it vastly easier to create a new OS, port an existing OS to the x86 (or in the future, to other architectures supported by the OSkit), or enhance an OS to support a wider range of devices, filesystem formats, executable formats, or network services. The OSKit also works well for constructing OS-related programs, such as boot loaders or OS-level servers atop a microkernel.
• Small and embedded FreeBSD (PicoBSD) PicoBSD is a one floppy version of FreeBSD which in its different variations allows you to have secure dial-up access, small diskless router, or even a dial-in server. All of this on only one standard 1.44MB floppy disk. It runs on a minimum 386SX CPU with 8MB of RAM, and no hard drive is required!

Misc

• GLOBAL is a common source code tag system that works the same way across diverse environments. Currently, it supports the shell command line, the nvi editor, web browser, the emacs editor, and the elvis editor, and the supported languages are C, Yacc, and Java.
• PAO: Mobile Computing page, laptops running FreeBSD 2.2.X and 3.X Laptop users looking for PC Card (aka PCMCIA) support under FreeBSD 2.2.X and 3.X should look at the PAO project for laptop support (FreeBSD 4.X and higher are provided with laptop support).
• FreeBSD source code tour. A hypertext cross referenced presentation of the FreeBSD kernel source code. The versions indexed are -CURRENT and RELENG_4.
• Enteruser: A Replacement for Adduser
• FreeBSD libh Project. Libh is a wrapper that allows tcl scripts to run in a sort of sandbox and interface to other libraries. Some of the stock libraries that come with libh that can be called from the Tcl scripts include a generic user interface library, which uses Turbo Vision for its console backend, and Qt for its X11 backend. Libh also includes a new package system that uses Zip archives and various per-package scripts among other things. It also includes the beginnings of a new sysinstall.
• Binary Updater (binup). The FreeBSD Binary Updater Project aims to provide a secure mechanism for the distribution of binary updates for FreeBSD. This system is a client / server mechanism that allows clients to install any known "profile" or release of FreeBSD over the network. Where a specific profile might contain a specific set of FreeBSD software to install, additional packages, and configuration actions that make it more ideal for a specific environment (ie FreeBSD 4.3 Secure Web server profile).
• The FreeBSD C99 & POSIX® Conformance Project aims to implement all requirements of the ISO 9899:1999 (C99) and IEEE 1003.1-2001 (POSIX) standards.
• CVSweb is a WWW interface for CVS repositories with which you can browse a file hierarchy on your browser to view each file's revision history in a very handy manner.
