Free radius server software for linux

Campus Chat Server project is a chat server intended for use in the Cadiz University campus network.
Enhancements:
- hash_maps are now used instead of maps, so the cost of lookup or insertion is O(1) in the average case, instead of O(logn).

ArrowHead ASP Server is a Java Servlet which supports the ASP syntax and the VBScript programming language. It aims to support VBScript version 3.1 and the standard set of COM objects, but has a little ways to go yet.

It is extendable using Java objects and the Server.CreateObject syntax. It has been developed and tested under Apache 2.x and Tomcat 5.0.x, but should run under any Java servlet server.

RIPE Whois Server provides support for domain records and lookups.

This is a whois database server. The RIPE Whois server uses a backend SQL database to allow support for very large repositories. There is support for IPv6 records and lookups. Both RPSL and RIPE181 are supported.

Radiuslib provides a complete RADIUS protocol and utility library for Ruby.
Radiuslib is a complete RADIUS protocol and utility library for the Ruby programming language. It includes a very featureful, RFC- compliant protocol implementation, as well as parser classes for RADIUS dictionaries, Cistron-format "users" files, and standard "detail" accounting logs.
Main features:
- Full VSA support, even those quirky USR VSAs. All of the complexity of VSA handling is below the surface; you treat them like any other attribute, and Radiuslib handles the more complex packing and unpacking these attributes require.
- The authentication classes support both PAP and CHAP. It has been a frequent annoyance to me that more libraries (esp. Perls) dont support CHAP. Radiuslib handles both authentication methods seamlessly.
- Encodes and decodes filters in the Ascend binary filter format (abinary).
- Idiomatic, Ruby-ish API. I tried to implement lots of useful iterators, and most classes that represent indexable data can be accessed as youd expect, with the familiar Hash-like [] and []= methods.
- The "Request" classes include client-side networking, with configurable timeout & retransmission.
- A complete, RFC-compliant implementation of the protocol, appropriate for client or server use. Both authentication and accounting are supported.
- A higher-level RADIUS request handler, encapsulating an entire RADIUS authentication or accounting transaction.
- A dictionary parser supporting almost all available formats in use today.
- A read/write parser for Cistron-format "users" files, commonly used to store user authentication information.
- A read/write parser for Cistron-format "users" files in DBM format (TBA).
- A parser for RADIUS accounting "detail" files. This is another standard file format used by RADIUS servers to log accounting data.

uRadiusLib is a full, small, and easy to use C RADIUS client library. It includes full AAA example code with complete attribute sets.

It provides AAA via a very easy C API for your applications. uRadiusLib is based on the Cistron and Livingstone radiusd code.

It was originally designed to be used in embedded Linux applications with uClibC/Buildroot or similar, but can be used anywhere.

Installation:

cd liburadius
make
make install

cd examples
#setup hardcoded for your radius server
#See PLAN for API
vi testauth.c
make testauth
./testauth

#setup hardcoded for your radius server
#See PLAN for API
vi testacct.c
make testacct
./testacct

Zero Calorie DNS is a domain name server for which the binary weighs in at 26K, that has no dependencies other than the minimal FreeBSD 6.0 installation.

The server responds to "name server" (NS), "start of authority" (SOA), "address record" (A), "reverse address" (PTR), and "mail exchanger" (MX) requests. The server is fairly fast because the feature set has been trimmed down to the bare minimum.

A few things are hard-coded so that a two minute setup is easy to accomplish. The hard-coding means that it may not be for everyone, however.

Darwin Calendar Server provides a CalDAV server.

The Darwin Calendar Server is a standards-compliant server that allows multiple users to collaboratively share calendaring information. It provides a shared location on the network to store schedules, and allows users to send each other and manage invitations.

In order to provide interoperability with multiple calendaring clients, the server implements the CalDAV protocol, which is an extension of WebDAV, which is in turn an extension of HTTP.
