#  Define RADIUS clients (usually a NAS, Access Point, etc.).

#
#  Defines a RADIUS client.
#
#  '127.0.0.1' is another name for 'localhost'.  It is enabled by default,
#  to allow testing of the server after an initial installation.  If you
#  are not going to be permitting RADIUS queries from localhost, we suggest
#  that you delete, or comment out, this entry.
#
#

#
#  Each client has a "short name" that is used to distinguish it from
#  other clients.
#
#  In version 1.x, the string after the word "client" was the IP
#  address of the client.  In 2.0, the IP address is configured via
#  the "ipaddr" or "ipv6addr" fields.  For compatibility, the 1.x
#  format is still accepted.


client localhost {
        #  Only *one* of ipaddr, ipv4addr, ipv6addr may be specified for
        #  a client.
        #
        #  ipaddr will accept IPv4 or IPv6 addresses with optional CIDR
        #  notation '/<mask>' to specify ranges.
        #
        #  ipaddr will accept domain names e.g. example.org resolving
        #  them via DNS.
        #
        #  If both A and AAAA records are found, A records will be
        #  used in preference to AAAA.
        ipaddr = 127.0.0.1

        #  Same as ipaddr but allows v4 addresses only. Requires A
        #  record for domain names.
#       ipv4addr = *    # any.  127.0.0.1 == localhost

        #  Same as ipaddr but allows v6 addresses only. Requires AAAA
        #  record for domain names.
#       ipv6addr = ::   # any.  ::1 == localhost

        #
        #  A note on DNS:  We STRONGLY recommend using IP addresses
        #  rather than host names.  Using host names means that the
        #  server will do DNS lookups when it starts, making it
        #  dependent on DNS.  i.e. If anything goes wrong with DNS,
        #  the server won't start!
        #
        #  The server also looks up the IP address from DNS once, and
        #  only once, when it starts.  If the DNS record is later
        #  updated, the server WILL NOT see that update.
        #

        #
        #  The transport protocol.
        #
        #  If unspecified, defaults to "udp", which is the traditional
        #  RADIUS transport.  It may also be "tcp", in which case the
        #  server will accept connections from this client ONLY over TCP.
        #
        proto = *
        #  depends COMPLETELY on this secret!  We recommend using a
        #  shared secret that is composed of:
        #
        #       upper case letters
        #       lower case letters
        #       numbers
        #
        #  And is at LEAST 8 characters long, preferably 16 characters in
        #  length.  The secret MUST be random, and should not be words,
        #  phrase, or anything else that is recognisable.
        #
        #  The default secret below is only for testing, and should
        #  not be used in any real environment.
        #
        secret = testing123

        #
        #  Old-style clients do not send a Message-Authenticator
        #  in an Access-Request.  RFC 5080 suggests that all clients
        #  SHOULD include it in an Access-Request.  The configuration
        #  item below allows the server to require it.  If a client
        #  is required to include a Message-Authenticator and it does
        #  not, then the packet will be silently discarded.
        #
        #  allowed values: yes, no
        require_message_authenticator = no
        
        #
        #  The short name is used as an alias for the fully qualified
        #  domain name, or the IP address.
        #
        #  It is accepted for compatibility with 1.x, but it is no
        #  longer necessary in >= 2.0

        # the following three fields are optional, but may be used by
        # checkrad.pl for simultaneous use checks

        # The nas_type tells 'checkrad.pl' which NAS-specific method to
        #  use to query the NAS for simultaneous use.

        #  The 'naspasswd' file is currently used to store the NAS

        #  when querying the NAS for simultaneous use.

        #  As of 2.0, clients can also be tied to a virtual server.

        #  item, as in the example below.

#       virtual_server = home1
