SME Server
Koozali SME server (also known as the SME Server, formerly e-smith server and gateway) is a Linux distribution based on Red Hat Enterprise Linux and can act a server-only or server and Gateway. Core features include internet services such as HTTP, FTP or email servers and Firewall. It is also geared towards the deployment of local network utilities like file servers, print servers and anti-virus filters. An intuitive web interface allows administrators to monitor, deploy and maintain services. The distribution is non-commercial and community based. History The distribution was created under the name of e-smith server and gateway in 1999, by the eponymous company e-smith inc. founded by Joseph and Kim Morrison in 1998. When e-smith inc. was acquired by Mitel Networks in 2001, the distribution was rebranded Mitel SME Server. Mitel decided to end support for SME in the end of November 2003 to focus on its commercial version Managed Application Server (6000 MAS). The project was ta ...

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Qpsmtpd
qpsmtpd is an SMTP daemon written in Perl. It was originally designed to be a drop-in replacement for ''qmail-smtpd'', the SMTP component of qmail, and it is now also compatible with Postfix, Exim, sendmail and virtually any software that "speaks SMTP". It has a flexible plugin system, making it easy to interoperate with other pieces in a mail system. Its main purpose is to allow mail administrators to perform more advanced spam filtering than is possible with other SMTP daemons. As one example of dozens, the earlytalker plugin blocks many viruses and mass mailers based on their characteristic violation of basic protocol, even before they start sending mail data. The program's main author is Ask Bjørn Hansen. It is licensed under the MIT License. Qpsmtpd Plugins A defining virtue of qpsmtpd is its plugin system and collection of plugins. In addition to basic plugins qpsmtpd has a suite of additional plugins that provide integration with external mail filters and processo ...

Unix Variants
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley (BSD), Microsoft (Xenix), Sun Microsystems (SunOS/Solaris), HP/ HPE (HP-UX), and IBM (AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are characterized by a modular design that is sometimes called the "Unix philosophy". According to this philosophy, the ...

RPM-based Linux Distributions
RPM Package Manager (RPM) (originally Red Hat Package Manager, now a recursive acronym) is a free and open-source package management system. The name RPM refers to the file format and the package manager program itself. RPM was intended primarily for Linux distributions; the file format is the baseline package format of the Linux Standard Base. Although it was created for use in Red Hat Linux, RPM is now used in many Linux distributions such as PCLinuxOS, Fedora, AlmaLinux, CentOS, openSUSE, OpenMandriva and Oracle Linux. It has also been ported to some other operating systems, such as Novell NetWare (as of version 6.5 SP3), IBM's AIX (as of version 4), IBM i, and ArcaOS. An RPM package can contain an arbitrary set of files. Most RPM files are “binary RPMs” (or BRPMs) containing the compiled version of some software. There are also “source RPMs” (or SRPMs) containing the source code used to build a binary package. These have an appropriate tag in the file header that di ...

Horde (software)
Horde is a free web-based groupware. The components of this groupware rest on the Horde framework. This PHP-based framework provides all the elements required for rapid web application development. Horde offers applications such as the Horde IMP email client, a groupware package (calendar, notes, tasks, file manager), a wiki and a time and task tracking software. History The Horde framework evolved from the IMP (Internet Messaging Project) webmail that Chuck Hagenbuch published on Freshmeat in 1998. A constant stream of feature requests not all fitting for a webmail application led to the development of a more generic web application backbone: the Horde framework. The first announcement on Freshmeat was version 1.3.3 at the beginning of 2001. The release of Horde 2.0 and IMP 3.0 was the first one with two truly separate components. Horde as a generic web application framework primarily supported the webmail as well as a set of groupware applications by the time Horde 3.0 w ...

Samba (software)
Samba is a free software re-implementation of the SMB networking protocol, and was originally developed by Andrew Tridgell. Samba provides file and print services for various Microsoft Windows clients and can integrate with a Microsoft Windows Server domain, either as a Domain Controller (DC) or as a domain member. As of version 4, it supports Active Directory and Microsoft Windows NT domains. Samba runs on most Unix-like systems, such as Linux, Solaris, AIX and the BSD variants, including Apple's macOS Server, and macOS client ( Mac OS X 10.2 and greater). Samba also runs on a number of other operating systems such as OpenVMS and IBM i. Samba is standard on nearly all distributions of Linux and is commonly included as a basic system service on other Unix-based operating systems as well. Samba is released under the terms of the GNU General Public License. The name '' Samba'' comes from SMB (Server Message Block), the name of the proprietary protocol used by the Micro ...

Iptables
iptables is a user-space utility program that allows a system administrator to configure the IP packet filter rules of the Linux kernel firewall, implemented as different Netfilter modules. The filters are organized in different tables, which contain chains of rules for how to treat network traffic packets. Different kernel modules and programs are currently used for different protocols; ''iptables'' applies to IPv4, ''ip6tables'' to IPv6, ''arptables'' to ARP, and ' to Ethernet frames. iptables requires elevated privileges to operate and must be executed by user root, otherwise it fails to function. On most Linux systems, iptables is installed as and documented in its man pages, which can be opened using man iptables when installed. It may also be found in /sbin/iptables, but since iptables is more like a service rather than an "essential binary", the preferred location remains . The term ''iptables'' is also commonly used to inclusively refer to the kernel-level componen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Djbdns
The djbdns software package is a DNS implementation. It was created by Daniel J. Bernstein in response to his frustrations with repeated security holes in the widely used BIND DNS software. As a challenge, Bernstein offered a $1000 prize for the first person to find a security hole in djbdns, which was awarded in March 2009 to Matthew Dempsky. , djbdns's tinydns component was the second most popular DNS server in terms of the number of domains for which it was the authoritative server, and third most popular in terms of the number of DNS hosts running it. djbdns has never been vulnerable to the widespread cache poisoning vulnerability reported in July 2008, but it has been discovered that it is vulnerable to a related attack. The source code has not been centrally managed since its release in 2001, and was released into the public domain in 2007. As of March 2009, there are a number of forks, one of which is dbndns (part of the Debian Project), and more than a dozen patches to ...
