ora aggiungiamo alle interfacce gestite da batman wlan0
   
 
batctl if add wlan0
 
batctl if add wlan0
   
ifconfig bat0
+
dovremmo aver creato bat0, la tiriamo su
   
  +
ifconfig bat0 up
   
iwconfig wlan0 mode ad-hoc essid 10-tsacnaD.lime channel 1
+
e poi controlliamo se è tutto ok, non ha particolari configurazioni
   
batctl tcpdump wlan0

ifconfig bat0

Un'analisi della configurazione già funzionante preparata come da How To.

Appena entrati sul router si vede che su wlan0 è presente una interfaccia virtuale wlan0-1.

Questa è l'interfaccia che i router usano per la rete di backbone, l'interfaccia è configurata in modalità ad hoc tipica delle reti mesh, il nome dell'essid probabilmente è generato random con un suffisso che però probabilmente dovrà esssere uguale per tutti i nodi (da verificare).

in pratica i link verdi che si vedono in questa figura: http://dev.libre-mesh.org/attachments/download/19

Per la parte invece di distribuzione del segnale quella che è usata normalmente sugli access point viene usata wlan0 in modalità master con essid inpostato in fase di configurazione con chef nella pagina How To.

A questo punto possiamo collegarci normalmente alla rete wifi ninuxbo con i vari device e navigare.

Oppure molto più divertente analizzare il funzionamento della rete mesh collegandoci con un pc a vedere informazioni scambiate dal protocollo batman.

Per prima cosa è necessario installare batman e batctl:

apt-get install batman batctl

caricare il modulo batctl

modprobe batman-adv 

eventualmente caricarlo di default all'avvio

echo "batman-adv" > /etc/modules

ora aggiungiamo alle interfacce gestite da batman wlan0

batctl if add wlan0

dovremmo aver creato bat0, la tiriamo su

ifconfig bat0 up

e poi controlliamo se è tutto ok, non ha particolari configurazioni

ifconfig bat0

ora colleghiam wlan0 in modalità ad-hoc alla rete mesh di backbone

iwconfig wlan0 mode ad-hoc essid 10-tsacnaD.lime channel 1
ifconfig wlano0 up

e vediamo se passa qualcosa di interessante

batctl tcpdump wlan0

tipo questo:

ora il nostro pc è in mesh sulla rete di backbone e vede gli altri nodi in questo caso 12:fe:ed:2b:19:e3
