NetBSD 5.0.1
UNIX-LIKE OPEN SOURCE OPERATING SYSTEM.
NetBSD is a free, secure, and highly portable Unix-like Open Source operating system available for many platforms, from 64-bit Opteron machines and desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent in both production and research environments, and it is user-supported with complete source. Many applications are easily available through The NetBSD Packages Collection.
NetBSD is a highly integrated system. In addition to its highly portable, high performance kernel, NetBSD features a complete set of user utilities, compilers for several languages, the X Window System, firewall software and numerous other tools, all accompanied by full source code. The NetBSD Packages Collection, pkgsrc, contains over 5,700 packages. Binary package releases for a number of platforms are currently in progress.
The NetBSD operating system is a full-featured, open source, UNIX-like operating system descended from the Berkeley Networking Release 2 (Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2. NetBSD runs on 57 different system architectures featuring 17 machine architectures across 17 distinct CPU families, and is being ported to more.
NetBSD is distributed in three forms: formal releases, NetBSD-release, and NetBSD-current. Formal releases are done periodically and include well-tested binaries, source code, and installation tools. NetBSD-release is a daily updated snapshot of the release branch, which normally will become the next patch release. NetBSD-current is a nightly distribution of the latest development sources, meant for people who want the absolute latest software, and don`t mind an occasional bug.
NetBSD 5.0 continues our long tradition with major improvements in stability, performance, networking, security, also includes support for two new platforms (iyonix and hp700), and many new peripherals.
Far reaching improvements to the network stack will not only provide better performance but also make NetBSD an excellent choice for a VPN gateway. PAM (Pluggable Authentication Modules) framework adds more flexibility to NetBSD`s user management and simplifies integration into heterogeneous networks. The kernel, libraries and utilities can now handle filesystems larger than two terabytes, and support for Xen 2.0 allows hosting many virtual servers on a single machine.
