LEAF Project
The LEAF (Linux Embedded Appliance Framework) Project is a collection of Linux distributions that began as a fork from the Linux Router Project (LRP) "linux-on-a-floppy" distribution. Most users of these distributions are primarily interested in router and firewall functions, particularly as combined with the convenience of major features of general Linux distributions such as shells, packet filtering, SSH servers, DNS services, file servers, webmin and the like. LEAF is a common choice when commercial NAT routers are insufficiently flexible or secure, or are unattractively nonconformant to open source philosophy. Characteristics LEAF is capable of running a powerful NAT firewall with several ancillary services on computer hardware generally considered obsolete, such as 486 workstations with no hard disk. LEAF is intended to work well with read-only storage media, such as write-protected floppy drives or optical discs. Distribution sizes range from a single floppy di ...

Bourne Shell
The Bourne shell (sh) is a Shell (computing), shell Command-line interface#Command-line interpreter, command-line interpreter for computer operating systems. The Bourne shell was the default Unix shell, shell for Version 7 Unix. Unix-like systems continue to have /bin/sh—which will be the Bourne shell, or a symbolic link or hard link to a compatible shell—even when other shells are used by most users. Developed by Stephen R. Bourne, Stephen Bourne at Bell Labs, it was a replacement for the Thompson shell, whose executable file had the same name—sh. It was released in 1979 in the Version 7 Unix release distributed to colleges and universities. Although it is used as an interactive command interpreter, it was also intended as a scripting language and contains most of the features that are commonly considered to produce structured programs. It gained popularity with the publication of ''The Unix Programming Environment'' by Brian Kernighan and Rob Pike—the first commercial ...

Workstation
A workstation is a special computer designed for technical or scientific applications. Intended primarily to be used by a single user, they are commonly connected to a local area network and run multi-user operating systems. The term ''workstation'' has been used loosely to refer to everything from a mainframe computer terminal to a PC connected to a network, but the most common form refers to the class of hardware offered by several current and defunct companies such as Sun Microsystems, Silicon Graphics, Apollo Computer, DEC, HP, NeXT, and IBM which powered the 3D computer graphics revolution of the late 1990s. Workstations offer higher performance than mainstream personal computers, especially in CPU, graphics, memory, and multitasking. Workstations are optimized for the visualization and manipulation of different types of complex data such as 3D mechanical design, engineering simulations like computational fluid dynamics, animation, medical imaging, image rendering, and ...

Daemon (computer Software)
In multitasking computer operating systems, a daemon ( or ) is a computer program that runs as a background process, rather than being under the direct control of an interactive user. Traditionally, the process names of a daemon end with the letter ''d'', for clarification that the process is in fact a daemon, and for differentiation between a daemon and a normal computer program. For example, is a daemon that implements system logging facility, and is a daemon that serves incoming SSH connections. In a Unix environment, the parent process of a daemon is often, but not always, the init process. A daemon is usually created either by a process forking a child process and then immediately exiting, thus causing init to adopt the child process, or by the init process directly launching the daemon. In addition, a daemon launched by forking and exiting typically must perform other operations, such as dissociating the process from any controlling terminal (tty). Such procedures are ...

Debian Sarge
Debian releases do not follow a fixed schedule. Recent releases have been made roughly biennially by the Debian Project. The most recent version of Debian is Debian version 11, codename "Bullseye". The next up and coming release of Debian is Debian 12 codename "Bookworm". Debian always has at least three release branches active at any time: "stable", "testing" and "unstable". The stable release is the most recent and up-to-date version of Debian. The testing release contains packages that have been tested from unstable. Testing has significantly more up-to-date packages than stable and is a close version of the future release candidate for stable. The unstable release (also known as sid) is the release where active development takes place. It is the most volatile version of Debian. When the Debian stable branch is replaced with a newer release, the current stable becomes an "oldstable" release. When the Debian stable branch is replaced again, the oldstable release becomes the " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shorewall
Shorewall is an open-source software, open source firewall (networking), firewall tool for Linux that builds upon the Netfilter (iptables/ipchains) system built into the Linux kernel, making it easier to manage more complex configuration schemes by providing a higher level of abstraction for describing rules using text files. Configuration It is not a daemon (computing), daemon since it does not run continuously, but rather configures rules in the kernel that allow and disallow traffic through the system. Shorewall is configured through a group of plain-text configuration files and does not have a graphical user interface, though a Webmin module is available separately. A monitoring utility packaged with Shorewall can be used to watch the status of the system as it operates and to assist in testing. Use Shorewall is mainly used in network installations (as opposed to a personal firewall, personal computer firewall), since most of its strength lies in its ability to work wi ...

Dropbear (software)
Dropbear is a software package written by Matt Johnston that provides a Secure Shell-compatible server and client. It is designed as a replacement for standard OpenSSH for environments with low memory and processor resources, such as embedded systems. It is a core component of OpenWrt and other router distributions. Dropbear was originally released in April 2003. Technology Dropbear implements version 2 of the Secure Shell (SSH) protocol. The cryptographic algorithms are implemented using third-party cryptographic libraries like LibTomCrypt included internally in the Dropbear distribution. It derives some parts from OpenSSH to handle BSD-style pseudo terminals. Features Dropbear implements the complete SSH version 2 protocol in both the client and the server. It does not support SSH version 1 backwards-compatibility in order to save space and resources, and to avoid the inherent security vulnerabilities in SSH version 1. SCP is also implemented. SFTP support relies on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BusyBox
BusyBox is a software suite that provides several Unix utilities in a single executable file. It runs in a variety of POSIX environments such as Linux, Android, and FreeBSD, although many of the tools it provides are designed to work with interfaces provided by the Linux kernel. It was specifically created for embedded operating systems with very limited resources. The authors dubbed it "The Swiss Army knife of Embedded Linux", as the single executable replaces basic functions of more than 300 common commands. It is released as free software under the terms of the GNU General Public License v2, after controversially deciding not to move to version 3. History Origins Originally written by Bruce Perens in 1995 and declared complete for his intended usage in 1996, BusyBox initially aimed to put a complete bootable system on a single floppy disk that would serve both as a rescue disk and as an installer for the Debian distribution. Since that time, it has been extended ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UClibc
__NOTOC__ In computing, uClibc (sometimes written µClibc) is a small C standard library intended for Linux kernel-based operating systems for embedded systems and mobile devices. uClibc was written to support μClinux, a version of Linux not requiring a memory management unit and thus suited for microcontrollers (uCs; the "u" is a Latin script typographical approximation - not a proper romanization, which would be letter "m" - of μ for "micro"). Development on uClibc started around 1999. uClibc was mostly written from scratch, but has incorporated code from glibc and other projects. The project lead is Erik Andersen, and the other main contributor is Manuel Novoa III. Licensed under the GNU Lesser General Public License, uClibc is free and open-source software. uClibc is much smaller than the glibc, the C library normally used with Linux distributions. While glibc is intended to fully support all relevant C standards across a wide range of hardware and kernel platforms, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
