Radius

Einführung

This package is based on the libradius of FreeBSD. This PECL adds full support for Radius Authentication (» RFC 2865) and Radius Accounting (» RFC 2866). This package is available for Unix (tested on FreeBSD and Linux) and for Windows.

Hinweis: An exact description for libradius can be found » here. A detailed description of the configuration file can be found » here.

Installation

Howto install the package?

  • untar the package (usually into php4/ext)
  • rename radius-x.x to radius
  • run ./buildconf in php4
  • run ./configure --enable-radius
  • make; make install
or if you would like to have it as .so:
  • untar the package
  • run phpize in the radius-x.x directory
  • run ./configure in the radius-x.x directory
  • make; make install

For Windows I recommend to use the php_radius.dll from » http://snaps.php.net/. Sie bekommen diese PECL Erweiterung von den verschiedenen PECL Schnappschuss-Seiten (wählen Sie das zu Ihrer PHP Version passende Repositorium aus): » PECL for PHP 4.3.x, » PECL for PHP 5.0.x oder » PECL Unstable.

Quickstart

Howto start?

  • get a radius resource
  • configure the library
  • create the request
  • put attributes
  • send the request
  • receive attributes
  • close the radius resource (optional)
Take also a look at the examples in this package.

The package contains an example php script. This script demonstrates howto authenticate with radius using PAP or CHAP (md5). If you authenticate with Microsoft Radius servers then its not possible to use CHAP (md5). If you would like to authenticate with Microsoft Servers you have to use MS-CHAPv1 or MS-CHAPv2, but its more complicated, because you need md4, sha1 and des to generate the right data. The enclosed examples demonstrate all authentication-methods, including MS-CHAPv1 and MS-CHAPv2. To get the MS-CHAP to work you need the mcrypt and the mhash extension, starting with version 1.2 of the package, the mcrypt extension is no longer needed.
