Config file format¶

Initial state of NFD daemon is configured using an INFO file.

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

  }
