Linux and Open Source Glossary
Apache
The most popular HTTP server in the world. http://www.apache.org.
Included in both KRUD Linux and KRUDserver. Tags: Software,
Open Source, HTTP, web server
audit2allow
SELinux, the Security Enhanced Linux, provides for fine
grained access control to applications and services. Setting up
this access control manually can be time consuming and
error-prone. audit2allow is a tool which watches the log of the normal
behavior on the system, and sets up rules to allow that behavior.
See:
for more information and an example. Tags: Linux,

BitTorrent
A file transfer program that uses a peer-to-peer network. It
is designed to allow popular downloads to be distributed quickly
without putting an unacceptable load on the central server. Many
Linux distributions are distributed using BitTorrent. KRUD Linux includes BitTorrent. Tags:

SSL Certificate
An SSL certificate, which we resell, is a way of identifying
your organization securely over the Internet. When you purchase an
SSL certificate, you demonstrate to the certificate providing
company that you are who you say you are. You then receive a small
file which is installed on your server which will
cryptographically securely provide information about your identity
so you can have a secure and private conversation on the Internet.
The Certificate company acts as a trusted third party which both
ends of the conversation look to to verify that the other end of
the conversation is being conducted by someone who can present the
correct certificate. SSL certificates can be used to secure any
Internet connection.
davfs
Distributed Authoring and Versioning (DAV) is a way for you
to easily modify files on a web server from your local
workstation, without having to learn how to use ftp or other
methods to transfer files between your local workstation and the
server. davfs allows you to mount a WebDAV server as another file
system, so you can 'cd' into it and change things, just as if it
were on your local disk. KRUD Linux
includes davfs. Tags: Software, SysAdmin, Internet
Fedora
The Fedora Project
is the open source, community version of Red Hat's
distribution. It is intended as a more up to date, dynamically
changing distribution, in comparison to the more slowly changing
commercial version Red Hat Enterprise Linux. KRUD Linux is based on current
versions of Fedora. Tags: Linux, SysAdmin
HTML
HyperText Markup Language. The specification for describing
the parts of a document so that they can be correctly displayed in
a web browser. It has gone through several versions and has now
been superseded by XHTML http://www.w3c.org. Tags:
Internet
HTTP
HyperText Transfer Protocol. The protocol which describes
HTML and XHTML web pages are served. http://www.w3c.org Tags:

kernel
The portion of an operating system which manages application
software request for access to device drivers. In the case of
Linux, it is the portion of a Linux distribution which is a
combination of the work of the kernel.org team, and distribution
packagers. As hardware changes, the kernel needs to change to take
advantage of changes in functionality. The kernel provides a
standard interface to applications by supporting standards such
as glibc and Posix. All of the source code to the Linux kernel is
available to learn from and to change. It may be installed on
your system under /usr/src/linux* Tags: Linux, SysAdmin
SELinux
Security Enhanced Linux, a project of the National Security
Agency (NSA), is an add-on to Linux which provides fine-grained
access control. It provides tools for ensuring that only
authorized users and programs can make changes to your system. It
is part of Fedora Core 2, CentOS4, RHEL 4 and later versions of
all of those distributions, and is available in
KRUD Linux and in KRUDserver Linux. Tags: Linux,
SysAdmin, Security
SGML
Standard Generalized Markup Language. A language for
describing markup languages. HTML, XML, and XHTML are all defined
within the framework of SGML. SGML tools can be used to verify
that a document has the correct form (no missing tags, specific
tags are contained only with the sorts of tags that make sense to
contain them.) Tags: Internet
XHTML
Extended HyperText Markup Language. The current
specification for describing the source of web pages. It is fully
SGML compliant. http://www.w3c.org
