RADIUS Attribute Types

These constants define RADIUS attribute types that can be used with radius_put_addr(), radius_put_attr(), radius_put_int() and radius_put_string().

RADIUS_USER_NAME (int)

The User-Name attribute. The attribute value is expected to be a string containing the name of the user being authenticated, and can be set using radius_put_attr().

RADIUS_USER_PASSWORD (int)

The User-Password attribute. The attribute value is expected to be a string containing the user's password, and can be set using radius_put_attr(). This value will be obfuscated on transmission as described in » section 5.2 of RFC 2865.

RADIUS_CHAP_PASSWORD (int)

The Chap-Password attribute. The attribute value is expected to be a string with the first byte containing the CHAP identifier, and the subsequent 16 bytes containing the MD5 hash of the CHAP identifier, the plaintext password and the CHAP challenge value concatenated together. Note that the CHAP challenge value should also be sent separately in a RADIUS_CHAP_CHALLENGE attribute.

Exemplo #1 Using CHAP passwords

<?php
// Firstly, we'll create an authentication handle and request.
$radh = radius_auth_open();
radius_add_server($radh, $server, $port, $secret, 3, 3);
radius_create_request($radh, RADIUS_ACCESS_REQUEST);

// Assuming $password contains the plaintext password, we now:

// Generate a challenge.
$challenge = mt_rand();

// Specify a CHAP identifier.
$ident = 1;

// Add the Chap-Password attribute.
$cp = hash('md5', pack('Ca*', $ident, $password.$challenge), true);
radius_put_attr($radh, RADIUS_CHAP_PASSWORD, pack('C', $ident).$cp);

// Add the Chap-Challenge attribute.
radius_put_attr($radh, RADIUS_CHAP_CHALLENGE, $challenge);

/* From here, you would add the remaining attributes and
* call radius_send_request(). */
?>

• RADIUS_COMP_NONE: No compression
• RADIUS_COMP_VJ: VJ TCP/IP header compression

RADIUS_LOGIN_IP_HOST (int)

The Login-IP-Host attribute. The attribute value is expected to the IP address to connect the user to, encoded as an int, which can be set using radius_put_addr().

RADIUS_LOGIN_SERVICE (int)

The Login-Service attribute. The attribute value is an int indicating the service to connect the user to on the login host. The value can be converted to a PHP integer via radius_cvt_int().

RADIUS_LOGIN_TCP_PORT (int)

RADIUS_CALLBACK_NUMBER (int)

The Callback-Number attribute. The attribute value is a string containing the dialing string to use for callback.

RADIUS_CALLBACK_ID (int)

The Callback-Id attribute. The attribute value is a string containing an implementation-specific name of the place to be called.

RADIUS_FRAMED_ROUTE (int)

The Framed-Route attribute. The attribute value is a string containing an implementation-specific set of routes to be configured for the user.

RADIUS_FRAMED_IPX_NETWORK (int)

The Framed-IPX-Network attribute. The attribute value is an int containing the IPX network to be configured for the user, or 0xFFFFFFFE to indicate that the RADIUS client should select the network, and can be accessed via radius_cvt_int().

RADIUS_STATE (int)

The State attribute. The attribute value is an implementation-defined string included in an Access-Challenge from a server that must be included in the subsequent Access-Request, and can be set using radius_put_attr().

RADIUS_CLASS (int)

The Class attribute. The attribute value is an arbitrary string included in an Access-Accept message that should then be sent to the accounting server in Accounting-Request messages, and can be set using radius_put_attr().

RADIUS_VENDOR_SPECIFIC (int)

The Vendor-Specific attribute. In general, vendor attribute values should be set using radius_put_vendor_addr(), radius_put_vendor_attr(), radius_put_vendor_int() and radius_put_vendor_string(), rather than directly.

This constant is mostly useful when interpreting vendor specific attributes in responses from a RADIUS server; when a vendor specific attribute is received, the radius_get_vendor_attr() function should be used to access the vendor ID, attribute type and attribute value.
