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

1. !/bin/sh /etc/rc.common
2. this version only works with "Backfire"!
3. /etc/init.d/ffp-apdb enable
