===== Alfred =====
A.L.F.R.E.D - Almighty Lightweight Fact Remote Exchange Daemon
<blockquote>alfred is a user space daemon for distributing arbitrary local information over the mesh/network in a decentralized fashion. This data can be anything which appears to be useful - originally designed to replace the batman-adv visualization (vis), you may distribute hostnames, phone books, administration information, DNS information, the local weather forecast ...

[[https://github.com/ffnord/alfred/blob/master/README ]]

==== Start / Stop/ Staus ====

  service alfred start
  [ ok ] Starting A.L.F.R.E.D: alfred.

  service alfred stop

  service alfred status
  [ ok ] alfred is running.



==== Debugging ====

  ps -ef |grep alfred
  root      1149     1  0 21:03 ?        00:00:00 /usr/sbin/alfred -i bat0 -b bat0 -m

=== Abfragen ===

Sind Nodes online, die gluon-announce installiert und am laufen haben, sollte man json/gzip Daten erhalten:

  alfred -r 158 -u /var/run/alfred-wi.sock
   [...]
   { "xx:xx:xx:xx:xx:xx", "\xxx\xxx [...] \xxx\xxx" },
   [...]

Ist alfred-json installiert kann man sich die Daten gleich mit entpacken lassen:

  alfred -r 158 -s /var/run/alfred.sock -z
   [...]
   {
       "xx:xx:xx:xx:xx:xx": {
           "location": {
             "longitude": 0.0,
             "latitude": 0.0
           },
           "network": {
             "mac": "xx:xx:xx:xx:xx:xx",
             [...]
          },
          [...]
       },
       [...]
   }
   [...]

Hier nervt: Zur Angabe des Sockets nutzt alfred-json den Flag -s, alfred hingegen -u.



Wenn bereits ein Router in der Hood ist, kann mit

  alfred -r 158 -u /var/run/xx.sock 


[[https://github.com/FreifunkFranken/alfred-json]]

  alfred-json -zr 158 -s /var/run/alfred.sock
  
  alfred-json -zr 158
  
 Datensatz 158 und 159 sollten daten liefern
Bzw. Datensatz 1
===== Unbound =====

==== Starten Stoppen ====
  # /etc/init.d/unbound status
  [ ok ] unbound is running.
  
  # /etc/init.d/unbound start
  [ ok ] unbound is starting


  # /etc/init.d/unbound stop
  [ ok ] unbound is stopping
