 +<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 ...

 +
 +=== 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
