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 process section contains settings of nfd process

    process

    {

      pidfile /tmp/nfd.pid ; filename to write PID upon startup

    }

    ; 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 keys

    authorizations

    {

      ; an authorize section grants privileges to a key

      authorize

      {

        keyfile "/tmp/key1.pub" ; public key file

        privileges ; set of privileges granted to this public key

        {

          fib,

          stats

        }

      }

      authorize

      {

        keyfile "/tmp/key2.pub" ; public key file

        privileges ; set of privileges granted to this public key

        {

          face

        }

      }

    }
