    # This is a sample configuration file for freeDiameter daemon.
    
    # Most of the options can be omitted, as they default to reasonable values.
    # Only TLS-related options must be configured properly in usual setups.
    
    # It is possible to use "include" keyword to import additional files
    # e.g.: include "/etc/freeDiameter.d/*.conf"
    # This is exactly equivalent as copy & paste the content of the included file(s) 
    # where the "include" keyword is found.

    # The port this peer is listening on for incoming TLS-protected connections (TCP and SCTP).
    # See TLS_old_method for more information about TLS flavours.

    #SecPort = 5868;
    
    # Use RFC3588 method for TLS protection, where TLS is negociated after CER/CEA exchange is completed 
    # on the unsecure connection. The alternative is RFC6733 mechanism, where TLS protects also the 
    # CER/CEA exchange on a dedicated secure port.
    # This parameter only affects outgoing connections. 
    # The setting can be also defined per-peer (see Peers configuration section).
    # Default: use RFC6733 method with separate port for TLS.

    ##  TLS Configuration
    
    # TLS is managed by the GNUTLS library in the freeDiameter daemon.
    # You may find more information about parameters and special behaviors
    # in the relevant documentation.
    # http://www.gnu.org/software/gnutls/manual/
    
    # Credentials of the local peer
    # The X509 certificate and private key file to use for the local peer.
    # The files must contain PKCS-1 encoded RSA key, in PEM format.
    # (These parameters are passed to gnutls_certificate_set_x509_key_file function)
    # Default : NO DEFAULT
    #TLS_Cred = "<x509 certif file.PEM>" , "<x509 private key file.PEM>";
    #TLS_Cred = "/etc/ssl/certs/freeDiameter.pem", "/etc/ssl/private/freeDiameter.key";
    TLS_Cred = "/open5gs/tls/tls.crt", "/open5gs/tls/tls.key";
    
    # Certificate authority / trust anchors
    # The file containing the list of trusted Certificate Authorities (PEM list)
    # (This parameter is passed to gnutls_certificate_set_x509_trust_file function)
    # The directive can appear several times to specify several files.
    # Default : GNUTLS default behavior
    #TLS_CA = "<file.PEM>";
    TLS_CA = "/open5gs/diameter-ca/cacert.pem";
    
    # Certificate Revocation List file
    # The information about revoked certificates.
    # The file contains a list of trusted CRLs in PEM format. They should have been verified before. 
    # (This parameter is passed to gnutls_certificate_set_x509_crl_file function)
    # Note: openssl CRL format might have interoperability issue with GNUTLS format.
    # Default : GNUTLS default behavior
    #TLS_CRL = "<file.PEM>";
    
    # GNU TLS Priority string
    # This string allows to configure the behavior of GNUTLS key exchanges 
    # algorithms. See gnutls_priority_init function documentation for information.
    # You should also refer to the Diameter required TLS support here:
    #   http://tools.ietf.org/html/rfc6733#section-13.1
    # Default : "NORMAL"
    # Example: TLS_Prio = "NONE:+VERS-TLS1.1:+AES-128-CBC:+RSA:+SHA1:+COMP-NULL";
    #TLS_Prio = "NORMAL";
    
    # Diffie-Hellman parameters size
    # Set the number of bits for generated DH parameters
    # Valid value should be 768, 1024, 2048, 3072 or 4096.
    # (This parameter is passed to gnutls_dh_params_generate2 function, 
    # it usually should match RSA key size)
    # Default : 1024
    #TLS_DH_Bits = 1024;
    
    # Alternatively, you can specify a file to load the PKCS#3 encoded
    # DH parameters directly from. This accelerates the daemon start 
    # but is slightly less secure. If this file is provided, the
    # TLS_DH_Bits parameters has no effect.
    # Default : no default.
    #TLS_DH_File = "<file.PEM>";
    
    
    ##############################################################
    ##  Timers configuration
    
    # The Tc timer of this peer.
    # It is the delay before a new attempt is made to reconnect a disconnected peer.
    # The value is expressed in seconds. The recommended value is 30 seconds.
    # Default: 30
    #TcTimer = 30;
    
    # The Tw timer of this peer.
    # It is the delay before a watchdog message is sent, as described in RFC 3539.
    # The value is expressed in seconds. The default value is 30 seconds. Value must
    # be greater or equal to 6 seconds. See details in the RFC.
    # Default: 30
    #TwTimer = 30;
    
    ##############################################################
    ##  Applications configuration
    
    # Disable the relaying of Diameter messages?
    # For messages not handled locally, the default behavior is to forward the
    # message to another peer if any is available, according to the routing 
    # algorithms. In addition the "0xffffff" application is advertised in CER/CEA 
    # exchanges.
    # Default: Relaying is enabled.
    #NoRelay;
    
    # Number of server threads that can handle incoming messages at the same time.
    # Default: 4
    #AppServThreads = 4;
    
    # Other applications are configured by loaded extensions.
    
    ##############################################################
    ##  Extensions configuration
    
    #  The freeDiameter framework merely provides support for
    # Diameter Base Protocol. The specific application behaviors,
    # as well as advanced functions, are provided
    # by loadable extensions (plug-ins).
    #  These extensions may in addition receive the name of a 
    # configuration file, the format of which is extension-specific.
    #
    # Format:
    #LoadExtension = "/path/to/extension" [ : "/optional/configuration/file" ] ;
    #
    # Examples:
    #LoadExtension = "extensions/sample.fdx";
    #LoadExtension = "extensions/sample.fdx":"conf/sample.conf";
    
    # Extensions are named as follow:
    # dict_* for extensions that add content to the dictionary definitions.
    # dbg_*  for extensions useful only to retrieve more information on the framework execution.
    # acl_*  : Access control list, to control which peers are allowed to connect.
    # rt_*   : routing extensions that impact how messages are forwarded to other peers.
    # app_*  : applications, these extensions usually register callbacks to handle specific messages.
    # test_* : dummy extensions that are useful only in testing environments.
    
    
    # The dbg_msg_dump.fdx extension allows you to tweak the way freeDiameter displays some
    # information about some events. This extension does not actually use a configuration file
    # but receives directly a parameter in the string passed to the extension. Here are some examples:
    ## LoadExtension = "dbg_msg_dumps.fdx" : "0x1111"; # Removes all default hooks, very quiet even in case of errors.
    ## LoadExtension = "dbg_msg_dumps.fdx" : "0x2222"; # Display all events with few details.
    ## LoadExtension = "dbg_msg_dumps.fdx" : "0x0080"; # Dump complete information about sent and received messages.
    # The four digits respectively control: connections, routing decisions, sent/received messages, errors.
    # The values for each digit are:
    #  0 - default - keep the default behavior
    #  1 - quiet   - remove any specific log
    #  2 - compact - display only a summary of the information
    #  4 - full    - display the complete information on a single long line
    #  8 - tree    - display the complete information in an easier to read format spanning several lines.
    
    LoadExtension = "/usr/lib/aarch64-linux-gnu/freeDiameter/dbg_msg_dumps.fdx" : "0x8888";
    LoadExtension = "/usr/lib/aarch64-linux-gnu/freeDiameter/dict_rfc5777.fdx";

    ##  Peers configuration
    
    #  The local server listens for incoming connections. By default,
    # all unknown connecting peers are rejected. Extensions can override this behavior (e.g., acl_wl).
    # 
    #  In addition to incoming connections, the local peer can
    # be configured to establish and maintain connections to some 
    # Diameter nodes and allow connections from these nodes.
    #  This is achieved with the ConnectPeer directive described below.
    #
    # Note that the configured Diameter Identity MUST match
    # the information received inside CEA, or the connection will be aborted.
    #
    # Format:
    #ConnectPeer = "diameterid" [ { parameter1; parameter2; ...} ] ;
    # Parameters that can be specified in the peer's parameter list:
    #  No_TCP; No_SCTP; No_IP; No_IPv6; Prefer_TCP; TLS_old_method;
    #  No_TLS;       # assume transparent security instead of TLS. DTLS is not supported yet (will change in future versions).
    #  Port = 5868;  # The port to connect to
    #  TcTimer = 30;
    #  TwTimer = 30;

    #  TLS_Prio = "NORMAL";
    #  Realm = "realm.net"; # Reject the peer if it does not advertise this realm.
    # Examples:
    #ConnectPeer = "aaa.wide.ad.jp";
    #ConnectPeer = "old.diameter.serv" { TcTimer = 60; TLS_old_method; No_SCTP; Port=3868; } ;
    ConnectPeer = "hss.localdomain" { ConnectTo = "s6a.hss.open5gs.service"; No_TLS; };
