mod_access_referer is a module for the Apache HTTP Server that provides access control based on "Referer" HTTP header content.

Why is mod_access_referer useful?
Basically, it allow or deny the access based on what page is shown in the Web browser, which means that if you publish a document (picture, chart or other) in your site, the people will have to visit your Web site to access it, and no one will be able to link just the document.

Motivation:

There are many organizations that publish valuable files (pictures, charts, and other documents) in their Web sites. Those organizations want to make public those files, but at the same time they want the people having visiting their Web sites in order to get those files (example, in order to get revenue from sell banners which are shown at the Web site).

But, there are situations where the files are linked from other Web sites, other than the organization owns. In such situations, the organization is loosing twice: one because the people dont visit the organizations Web site to get the files, and another because the organization still pay the necessary bandwidth to get the files.

Most browsers today send the "Referer" HTTP header in each request that comes from another Web page. This can be used to track from where the resources are linked, but it can be used to allow or deny the access to such resources if the "Referer" is not a page from the organizations Web site.

mod_access_referer is an Apache module that understand the "Referer" HTTP header, and grant or deny access based on the Web page that refered the file.
The "Referer" HTTP header is sent by the browser to the server, and it contains the URL of the resource from where the URL of the asked resource was obtained. The document "Hypertext Transfer Protocol -- HTTP/1.1" RFC 2616 gives the following explanation:

"The Referer[sic] request-header field allows the client to specify, for the servers benefit, the address (URI) of the resource from which the Request-URI was obtained (the "referrer", although the header field is misspelled.) The Referer request-header allows a server to generate lists of back-links to resources for interest, logging, optimized caching, etc. It also allows obsolete or mistyped links to be traced for maintenance. The Referer field MUST NOT be sent if the Request-URI was obtained from a source that does not have its own URI, such as input from the user keyboard."

Rule Set Based Access Control (RSBAC) is a Free Software security extension for current Linux kernels. Rule Set Based Access Control is based on the Generalized Framework for Access Control (GFAC) by Abrams and LaPadula and provides a flexible system of access control based on several modules.
All security relevant system calls are extended by security enforcement code. This code calls the central decision component, which in turn calls all active decision modules and generates a combined decision. This decision is then enforced by the system call extensions.
Main features:
- Free Open Source (GPL) Linux kernel security solution
- Independent of governments and big companies
- Several well-known and new security models, like MAC, ACL and RC
- On-access virus scanning with the Dazuko interface
- Detailed control over individual user and program network accesses
- Fully access controlled kernel level user management
- Any combination of security models possible
- Easily extensible: write your own model for runtime registration
- Support for latest kernels and stable for production use
Enhancements:
- This release relates to kernel 2.4.34.5 and 2.6.22.1.
- There are important fixes with some compilation errors and an important bug with User Management password hashing, introduced with the newer 2.6 kernel crypto API.
- Some security has been added with safety measures against null pointers.

WebService::Google::Sets is a Perl access to Google Labs Sets site.

SYNOPSIS

use WebService::Google::Sets;

my @os_list = qw(Linux Windows Solaris);
my $expanded_os_list = get_gset(@os_list);

# check something came back
die "No results returned from server" unless $expanded_os_list;

foreach my $element (@$expanded_os_list) {
print $element, "n";
}

WebService::Google::Sets provides function based access to the Sets service hosted at Google Labs.

The Sets service attempts to expand the values you provide. The example provided in the SYNOPSIS would return an array that included "Windows NT", "HPUX" and "AIX" as values in addition to those supplied.

DACS is an open source identity management and access control system for web services. The web services can be virtually any static or computational resources provided through HTTP.
Main features:
- a flexible and powerful role-based access control system;
- a set of feature-rich authentication methods;
- an Apache 2.0.X module and suite of CGI programs;
- a federated identity management system (single sign-on);
- oriented towards (but not limited to) controlling access to web service requests made using standard web browsers;
- a collection of web services that can provide access control and identity management functionality to your middleware;
- a C/C++ toolkit for building new authentication and access control functionality into programs, whether web-based or not;
- for Unix-type platforms (currently), such as Linux, FreeBSD, and Solaris; and has
- an open, lightweight design and portable implementation.
DACS can help you to manage access to web resources in many situations, whether you have just one web server, several web servers at one site, or many web servers spread across the Internet.
You may find it to be useful simply as a universal authentication mechanism for a single Apache server or as a full-fledged, single sign-on multi-server identity management and access control system.
DACS may be of interest to developers more interested in authentication functionality than access control. DACS identities can be integrated with HTTP-based clients, whether interactive or not, and non-web based client/server applications.
Designed and implemented by DSS, development of DACS was initiated in May, 2001. DACS is a key component of Canadas National Forest Information System (NFIS).
Enhancements:
- This is primarily a bug fix and minor enhancements release. DACS is security software - we urge all users to upgrade to the latest release.

Bugzproxy project is a C# based assembly that provides access to a Bugzilla server, using the upcoming WebService interface of Bugzilla.

The assembly provides an object oriented API for accessing a Bugzilla server, allowing other tools to be easily built on top of this assembly. This includes command line tools, SCM integration tools, and MonoDevelop and Microsoft Visual Studio plugins.

ID3v2ChapterTool is an application which allows you to author and embed chapter information in your MP3 files. ID3v2 Chapter Tool project is part of the BBC open source initiative and is maintained as a Sourceforge project.

The application uses a new signalling specification that has been developed by ID3.org which is supported by APIs created in this project. These build on the Java ID3 API developed by Jens Vonderheide.

Chapters in this context could be any of the following:

- chapters within an audiobook
- articles within a podcast
- individual tracks within a multi-track audio file

At the most basic level this chapter information consists of the start time of each chapter you define, allowing listeners to skip easily to these points in the file during replay. However, chapters can also have descriptive information (e.g. title), images and URLs.

The information attached to each chapter can be used by media players to provide a dynamic display during replay. For example, the images attached to each chapter can be used to provide a slide show.

The ID3v2ChapterTool also allows you to create a Table of Contents (TOC).

At the most advanced level it is possible to define multiple TOCs for a single audio file. For example, one TOC could provide access to the entire audio file whilst a second TOC could provide access to a set of highlights.

Once chapter information is widely supported by media players it will enable some exciting new multimedia applications such Audio Encyclopaedias.

Python-LDAP provides an object-oriented API to access LDAP directory servers from Python programs. Mainly it wraps the OpenLDAP 2.x libs for that purpose.

Additionally the package contains modules for other LDAP-related stuff (e.g. processing LDIF, LDAPURLs, LDAPv3 schema, etc.).
