# 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.

##  Peer identity and realm

# The Diameter Identity of this daemon.
# This must be a valid FQDN that resolves to the local host.
# Default: hostname's FQDN
#Identity = "aaa.koganei.freediameter.net";
Identity = "smf.localdomain";

# The Diameter Realm of this daemon.
# Default: the domain part of Identity (after the first dot).

##  Transport protocol configuration

# The port this peer is listening on for incoming connections (TCP and SCTP).
# Default: 3868. Use 0 to disable.
Port = 3868;

# 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.
# Note: we use TLS/SCTP instead of DTLS/SCTP at the moment. This will change in future version of freeDiameter.
# Default: 5868. Use 0 to disable.
#SecPort = 5868;
SecPort = 0;

# 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_old_method;

# Disable use of TCP protocol (only listen and connect over SCTP)
# Default : TCP enabled
#No_TCP;

# Disable use of SCTP protocol (only listen and connect over TCP)
# Default : SCTP enabled
#No_SCTP;
# This option is ignored if freeDiameter is compiled with DISABLE_SCTP option.

# Prefer TCP instead of SCTP for establishing new connections.
# This setting may be overwritten per peer in peer configuration blocs.
# Default : SCTP is attempted first.
#Prefer_TCP;

# Default number of streams per SCTP associations.
# This setting may be overwritten per peer basis.
# Default : 30 streams
#SCTP_streams = 30;

##############################################################
##  Endpoint configuration

# Disable use of IP addresses (only IPv6)
# Default : IP enabled
#No_IP;

# Disable use of IPv6 addresses (only IP)
# Default : IPv6 enabled
#No_IPv6;

# Specify local addresses the server must bind to
# Default : listen on all addresses available.
#ListenOn = "202.249.37.5";
#ListenOn = "2001:200:903:2::202:1";
#ListenOn = "fe80::21c:5ff:fe98:7d62%eth0";

##  Server configuration

# How many Diameter peers are allowed to be connecting at the same time ?
# This parameter limits the number of incoming connections from the time
# the connection is accepted until the first CER is received.
# Default: 5 unidentified clients in paralel.
#ThreadsPerServer = 5;

##  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 = "@sysconfdir@/open5gs/tls/smf.crt", "@sysconfdir@/open5gs/tls/smf.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 = "@sysconfdir@/open5gs/tls/ca.crt";

# 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;
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 = "dbg_msg_dumps.fdx" : "0x8888";
LoadExtension = "dict_rfc5777.fdx";
LoadExtension = "dict_mip6i.fdx";
LoadExtension = "dict_nasreq.fdx";
LoadExtension = "dict_nas_mipv6.fdx";
LoadExtension = "dict_dcca.fdx";
LoadExtension = "dict_dcca_3gpp.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;
#  ConnectTo = "202.249.37.5";
#  ConnectTo = "2001:200:903:2::202:1";
#  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 = "pcrf.localdomain" { ConnectTo = "127.0.0.9"; No_TLS; };
