So einfach kann man seinen Laptop in das Freifunk-Netz als Knoten mit integrieren (Unter Ubuntu 12.04 getestet):
Installation
sudo apt-get install batctl
Kernelmodul laden:
sudo modprobe batman-adv
Version prüfen:
sudo batctl -v
Nicht alle Batmanversionen sind kompatibel - siehe: http://www.open-mesh.org/projects/batman-adv/wiki/Compatversion
Start-Script erstellen
Um sich mit batman.kiel.freifunk.net auf der Schnittstelle wlan0 mit der bssid 02:ca:ff:ee:ba:be zu verbinden erstelle folgendes script und nenne es z.B. /usr/local/sbin/freifunk-connect:
#! /bin/bash IFACE=wlan0 if [ "$(whoami &2>/dev/null)" != "root" ] && [ "$(id -un &2>/dev/null)" != "root" ] ; then echo "You must be root to run this script!"; exit 1 fi echo "stopping network-manager" service network-manager stop echo "pls wait" sleep 10 echo turn wlan iface off ifconfig $IFACE down echo set maximal transfer unit from standard 1500 to 1528 ifconfig $IFACE mtu 1528 echo turn wlan encryption off iwconfig $IFACE enc off echo start ad-hoc mode iwconfig $IFACE mode ad-hoc essid batman.kiel.freifunk.net ap 02:ca:ff:ee:ba:be channel 11 echo load module into kernel modprobe batman-adv echo adding iface to batman batctl if add $IFACE echo turn wlan iface on ifconfig $IFACE up echo turn batman iface on ifconfig bat0 up echo "batman.kiel.freifunk.net on $IFACE should be ready" echo "internet starting, this may take some minutes due to latency..." dhclient bat0 echo "internet connection IP:" ifconfig|grep Bcast echo echo "to resume normal networking just restart the networkmanager:" echo "service network-manager restart" echo "batctl if del $IFACE" echo "echo it can take a few minutes until network-manager gets a new route" echo
Wenn das script ausgeführt wird, dann ist dein Rechner Teil des Freifunk-Netzwerkes und mescht mit. Er kann so also auch als Brücke zwischen zwei Routern fungieren, die zu weit auseinander liegen.
