StatusUpdates

Freifunk Potsdam Accesspoints Update installieren

auf dem Accesspoint einloggen
mit einem Editor folgende Datei anlegen /etc/init.d/ffp-apdb
Datei öffnen und den Inhalt (siehe unten) reinkopieren
es müssen keine Änderungen vorgeneommen werden
script ausführbar machen mit: chmod 755 /etc/init.d/ffp-apdb
bootbar machen: /etc/init.d/ffp-apdb enable
starten: /etc/init.d/ffp-apdb start
fertig!

ffp-apdb Script

!/bin/sh /etc/rc.common
this version only works with "Backfire"!
