RADIUS Packet Types

RADIUS packets, whether requests or responses, always include a type. These constants are provided to make it easier to specify types when using radius_create_request() and when comparing the result of radius_send_request().

RADIUS_ACCESS_REQUEST (int)

An Access-Request, used to authenticate a user against a RADIUS server. Access request packets must include a RADIUS_NAS_IP_ADDRESS or a RADIUS_NAS_IDENTIFIER attribute, must also include a RADIUS_USER_PASSWORD, RADIUS_CHAP_PASSWORD or a RADIUS_STATE attribute, and should include a RADIUS_USER_NAME attribute.

RADIUS_ACCESS_ACCEPT (int)

An Access-Accept response to an Access-Request indicating that the RADIUS server authenticated the user successfully.

RADIUS_ACCESS_REJECT (int)

An Access-Reject response to an Access-Request indicating that the RADIUS server could not authenticate the user.

RADIUS_ACCESS_CHALLENGE (int)

An Access-Challenge response to an Access-Request indicating that the RADIUS server requires further information in another Access-Request before authenticating the user.

RADIUS_ACCOUNTING_REQUEST (int)

An Accounting-Request, used to convey accounting information for a service to the RADIUS server.

RADIUS_ACCOUNTING_RESPONSE (int)

An Accounting-Response response to an Accounting-Request.

RADIUS_COA_REQUEST (int)

A CoA-Request, sent from the RADIUS server to indicate that the authorisations within the user session have changed. A response must be sent in the form of a CoA-ACK or a CoA-NAK.

This constant is available in PECL radius 1.3.0 and later.

RADIUS_COA_ACK (int)

A CoA-ACK, sent to the RADIUS server to indicate that the user authorisations have been updated.

This constant is available in PECL radius 1.3.0 and later.

RADIUS_COA_NAK (int)

A CoA-NAK, sent to the RADIUS server to indicate that the user authorisations could not be updated.

This constant is available in PECL radius 1.3.0 and later.

RADIUS_DISCONNECT_REQUEST (int)

A Disconnect-Request, sent from the RADIUS server to indicate that the user session must be terminated.

This constant is available in PECL radius 1.3.0 and later.

RADIUS_DISCONNECT_ACK (int)

This constant is available in PECL radius 1.3.0 and later.
