NFD

# Config file format

Initial state of NFD daemon is configured using an [INFO file](http://www.boost.org/doc/libs/1_42_0/doc/html/boost_propertytree/parsers.html#boost_propertytree.parsers.info_parser).

## Example configuration

    ; the general section contains settings of nfd process

    general

    {

    }

    log

    {

    ; default_level specifies the logging level for modules

    ; that are not explicitly named. All debugging levels

    ; listed above the selected value are enabled.

    ;

    ; Valid levels:

    ;

    ;  NONE ; no messages

    ;  ERROR ; error messages

    ;  WARN ; warning messages

    ;  INFO ; informational messages (default)

    ;  DEBUG ; debugging messages

    ;  TRACE ; trace messages (most verbose)

    ;  ALL ; all messages

      default_level WARN

    ; You may override default_level by assigning a logging level

    ; to the desired module name. Module names can be found in two ways:

    ;

    ; Run:

    ;   nfd --modules

    ;

    ; Or look for NFD_LOG_INIT(<module name>) statements in .cpp files

      FibManager DEBUG

      Forwarder INFO

    }

    ; the face_system section defines what faces and channels are created

    face_system

    {

      ; the unix section contains settings of UNIX stream faces and channels

      unix

      {

        listen yes ; set to 'no' to disable UNIX stream listener, default 'yes'

        path /var/run/nfd.sock ; UNIX stream listener path

      }

      ; the tcp section contains settings of TCP faces and channels

      tcp

      {

        listen yes ; set to 'no' to disable TCP listener, default 'yes'

        port 6363 ; TCP listener port number

      }

      ; the udp section contains settings of UDP faces and channels

      udp

      {

        port 6363 ; UDP unicast port number

        idle_timeout 30 ; idle time (seconds) before closing a UDP unicast face

        keep_alive_interval 25; interval (seconds) between keep-alive refreshes

        ; NFD creates one UDP multicast face per NIC

        mcast yes ; set to 'no' to disable UDP multicast, default 'yes'

        mcast_port 56363 ; UDP multicast port number

        mcast_group 224.0.23.170 ; UDP multicast group (IPv4 only)

      }

      ; the ether section contains settings of Ethernet faces and channels

      ether

      {

        ; NFD creates one Ethernet multicast face per NIC

        mcast yes ; set to 'no' to disable Ethernet multicast, default 'yes'

        mcast_group 01:00:5E:00:17:AA ; Ethernet multicast group

      }

    }

    ; the authorizations section grants privileges to authorized NDN certificates

    authorizations

    {

      ; an authorize section grants privileges to an NDN certificate

      authorize

      {

        keyfile "/tmp/cert1.ndncert" ; NDN identity certificate file

        privileges ; set of privileges granted to this identity

        {

          fib

          stats

        }

      }

      authorize

      {

        keyfile "/tmp/cert2.ndncert" ; NDN identity certificate file

        privileges ; set of privileges granted to this identity

        {

          faces

        }

      }

    }
