=head1 SYNOPSIS

use Authen::Radius;

        { Name => 'User-Name', Value => 'myname' },
        { Name => 'Password', Value => 'mypwd' },
# RFC 2865 http://www.ietf.org/rfc/rfc2865.txt calls this attribute
# User-Password. Check your local RADIUS dictionary to find
# out which name is used on your system
#       { Name => 'User-Password', Value => 'mypwd' },
        { Name => 'h323-return-code', Value => '0' }, # Cisco AV pair
        { Name => 'Digest-Attributes', Value => { Method => 'REGISTER' } }

  }

=head1  DESCRIPTION

The C<Authen::Radius> module provides a simple class that allows you to
send/receive Radius requests/responses to/from a Radius server.

=head1 CONSTRUCTOR

=over 4

=item new ( Host => HOST, Secret => SECRET [, TimeOut => TIMEOUT]
    [,Service => SERVICE] [, Debug => Bool] [, LocalAddr => hostname[:port]]
    [,Rfc3579MessageAuth => Bool] [,NodeList= NodeListArrayRef])

Creates & returns a blessed reference to a Radius object, or undef on
failure.  Error status may be retrieved with C<Authen::Radius::get_error>
(errorcode) or C<Authen::Radius::strerror> (verbose error string).

The default C<Service> is C<radius>, the alternative is C<radius-acct>.
If you do not specify port in the C<Host> as a C<hostname:port>, then port
specified in your F</etc/services> will be used. If there is nothing
there, and you did not specify port either then default is 1645 for
C<radius> and 1813 for C<radius-acct>.

Optional parameter C<Debug> with a Perl "true" value turns on debugging
(verbose mode).

Optional parameter C<LocalAddr> may contain local IP/host bind address from
which RADIUS packets are sent.

Optional parameter C<Rfc3579MessageAuth> with a Perl "true" value turns on generating
of Message-Authenticator for Access-Request (RFC3579, section 3.2).
The Message-Authenticator is always generated for Status-Server packets.

Optional parameter C<NodeList> may contain a Perl reference to an array, containing a list of
Radius Cluster nodes. Each nodes in the list can be specified using a hostname or IP (with an optional
port number), i.e. 'radius1.mytel.com' or 'radius.myhost.com:1812'. Radius Cluster contains a set of Radius
servers, at any given moment of time only one server is considered to be "active"
(so requests are send to this server).
How the active node is determined? Initially in addition to the C<NodeList>
parameter you may supply the C<Host> parameter and specify which server should
become the first active node. If this parameter is absent, or the current
active node does not reply anymore, the process of "discovery" will be
performed: a request will be sent to all nodes and the consecutive communication
continues with the node, which will be the first to reply.

=head1 METHODS

=over 4

=item load_dictionary ( [ DICTIONARY ], [format => 'freeradius' | 'gnuradius'] )

Loads the definitions in the specified Radius dictionary file (standard
Livingston radiusd format). Tries to load C</etc/raddb/dictionary> when no
argument is specified, or dies. C<format> should be specified if dictionary has
other format (currently supported: FreeRADIUS and GNU Radius)

NOTE: you need to load valid dictionary if you plan to send RADIUS requests
with attributes other than just C<User-Name>/C<Password>.

=item check_pwd ( USERNAME, PASSWORD [,NASIPADDRESS] )

Checks with the RADIUS server if the specified C<PASSWORD> is valid for user
C<USERNAME>. Unless C<NASIPADDRESS> is specified, the script will attempt
to determine it's local IP address (IP address for the RADIUS socket) and
this value will be placed in the NAS-IP-Address attribute.
This method is actually a wrapper for subsequent calls to
C<clear_attributes>, C<add_attributes>, C<send_packet> and C<recv_packet>. It
returns 1 if the C<PASSWORD> is correct, or undef otherwise.

=item add_attributes ( { Name => NAME, Value => VALUE [, Type => TYPE] [, Vendor => VENDOR] [, Tag => TAG ] }, ... )

Adds any number of Radius attributes to the current Radius object. Attributes
are specified as a list of anon hashes. They may be C<Name>d with their
dictionary name (provided a dictionary has been loaded first), or with
their raw Radius attribute-type values. The C<Type> pair should be specified
when adding attributes that are not in the dictionary (or when no dictionary
was loaded). Values for C<TYPE> can be 'C<string>', 'C<integer>', 'C<ipaddr>',
'C<ipv6addr>', 'C<ipv6prefix>', 'C<ifid>' or 'C<avpair>'. The C<VENDOR> may be
Vendor's name from the dictionary or their integer id. For tagged attributes
(RFC2868) tag can be specified in C<Name> using 'Name:Tag' format, or by
using C<Tag> pair. TAG value is expected to be an integer.

=item get_attributes

Returns a list of references to anon hashes with the following key/value
pairs : { Name => NAME, Code => RAWTYPE, Value => VALUE, RawValue =>
RAWVALUE, Vendor => VENDOR, Tag => TAG, AttrName => NAME }. Each hash
represents an attribute in the current object. The C<Name> and C<Value> pairs
will contain values as translated by the dictionary (if one was loaded). The
C<Code> and C<RawValue> pairs always contain the raw attribute type & value as
received from the server.  If some attribute doesn't exist in dictionary or
type of attribute not specified then corresponding C<Value> undefined and
C<Name> set to attribute ID (C<Code> value). For tagged attribute (RFC2868), it
will include the tag into the C<NAME> as 'Name:Tag'. Original Name is stored in
C<AttrName>.  Also value of tag is stored in C<Tag> (undef for non-tagged
attributes).

=item clear_attributes

Clears all attributes for the current object.

=item send_packet ( REQUEST_TYPE, RETRANSMIT )

Packs up a Radius packet based on the current secret & attributes and
sends it to the server with a Request type of C<REQUEST_TYPE>. Exported
C<REQUEST_TYPE> methods are C<ACCESS_REQUEST>, C<ACCESS_ACCEPT>,
C<ACCESS_REJECT>, C<ACCESS_CHALLENGE>, C<ACCOUNTING_REQUEST>, C<ACCOUNTING_RESPONSE>,
C<ACCOUNTING_STATUS>, C<STATUS_SERVER>, C<DISCONNECT_REQUEST>, C<DISCONNECT_ACCEPT>,
C<DISCONNECT_REJECT>, C<COA_REQUEST>, C<COA_ACCEPT>, C<COA_REJECT>, C<COA_ACK>,
and C<COA_NAK>.
Returns the number of bytes sent, or undef on failure.

If the RETRANSMIT parameter is provided and contains a non-zero value, then
it is considered that we are re-sending the request, which was already sent
previously. In this case the previous value of packet identifier is used.

=item recv_packet ( DETECT_BAD_ID )

Receives a Radius reply packet. Returns the Radius Reply type (see possible
values for C<REQUEST_TYPE> in method C<send_packet>) or undef on failure. Note
that failure may be due to a failed recv() or a bad Radius response
authenticator. Use C<get_error> to find out.

If the DETECT_BAD_ID parameter is supplied and contains a non-zero value, then
calculation of the packet identifier is performed before authenticator check
and EBADID error returned in case when packet identifier from the response
doesn't match to the request. If the DETECT_BAD_ID is not provided or contains zero value then
EBADAUTH returned in such case.

=item set_timeout ( TIMEOUT )

Sets socket I/O activity timeout. C<TIMEOUT> should be specified in floating seconds
since the epoch.

=item get_error

Returns the last C<ERRORCODE> for the current object. Errorcodes are one-word
strings always beginning with an 'C<E>'.

=item strerror ( [ ERRORCODE ] )

Returns a verbose error string for the last error for the current object, or
for the specified C<ERRORCODE>.

=item error_comment

Returns the last error explanation for the current object. Error explanation
is generated by system call.

=item get_active_node

Returns currently active radius node in standard numbers-and-dots notation with
port delimited by colon.
