Radius

Introduction

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.

Note: 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/. Unbundled PECL extensions may be downloaded from: » http://pecl4win.php.net/

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.
