* [[Kanalwahl#Unsere_ssid_und_bssid|Unsere SSID und BSSID]]

<pre>
Leider stoße ich immer wieder an Knoten mit SSID ?.node.wien.funkfeuer.at
mit <node> der jewalige Knotenname.
Bei manchen Geräten mag das funktionieren, aber nicht bei allen.
Viele Geräte alt oder neu verlangen stehts nach der selben SSID,
womit viele dazu gezwingen werden die selbe SSID gleichfalls einzustellen.
Das führt dazu dass ein Knoten mit dem Namen bez10 sich zum Knoten
bez13 dann via SSID bez13.wien.funkfeuer.at verbinden muss.
Dann sendet aber der Knoten im 10. Bezirk die Kennung von 13. Bezirk
im SSID, was nicht der wahrheit entspricht. Zusätzlich kann sich dieser
Knoten im Bezirk 10 dann nicht mehr mit anderen regulären Knoten
mittels der richtigen SSID zu der selben Zeit verbinden!!!

Quelle https://lists.funkfeuer.at/pipermail/wien/2011-July/007687.html by Joe

danach nunmehr das tap device im Netzwerk hinzufügen

genauso läuft hornstein, vorübergehend auf dem Tunnelport für den schareck

Update: (Erich)
Wenn der Tunnel einfach nicht starten will, ist womöglich eine nicht unterstützte Option eingetragen.
Auskunft hierüber liefert der Befehl "logread" auf einer SSH-Konsole.
"option 'management' '127.0.0.1 31194'" kann auf neueren Backfire-Builds dieses Problem verursachen.

* Freischalten Channel 13

* Version von FreiFunk (Sven Ola) wien unter Fonera mit OLSR beschrieben ist

* Kamikaze, da funkzioniert das nicht so wie bei der Freifunk Firmware von Sven Ola. Hier ist für die Freischaltung nur ein Eintrag im /etc/config/wireless unter config 'wifi-device' und zwar option 'country' '276' notwendig.

<pre>
bei mir sieht es so aus

cat /etc/config/wireless

config 'wifi-device' 'wifi0'
option 'type' 'atheros'
option 'distance' '15000'
option 'diversity' '0'
option 'country' '276'
option 'channel' '13'

config 'wifi-iface'
option 'device' 'wifi0'
option 'network' 'wlan'
option 'mode' 'adhoc'
option 'mcast_rate' '5500'
option 'encryption' 'none'
option 'rate' '5500'
option 'ssid' 'v13.freiesnetz.www.funkfeuer.at'
option 'bssid' '26:A7:D4:E4:4F:4D'
