B.A.T.M.A.N. protocol for Ubuntu(Linux) Part-2

O.K. like I said in my previous post, B.A.T.M.A.N. need an interface to run.so in this post we gone a cover that part.

First you need to check your current interface by using this command,

iwconfig

If you see wlan0 there you are ready to go. But if you doesn’t see make sure Wi-Fi is enabled. And identified your Wi-Fi interface.

I made a small script that all the necessary commands needed to active B.A.T.M.A.N.

You can put this script (it’s a sh file) in /usr/local/sbin/ and execute it any ware you in.

By typing,

rockman.sh start

When you want to stop B.A.T.M.A.N. just type,

rockman.sh stop

And if you need help,

rockman.sh --help

You can download it from HERE or this is the source code of my script,

#Copyright © RockMan

#!/bin/bash

#Your Wi-Fi interface name.

IFACE=wlan0

#Any essid name you want but need to be same for all B.A.T.M.A.N.  nodes.

ESSID=rockman2

#I'm using channel 1.

CHANNEL=1

#This also must be same for all nodes.

CELLID=02:12:34:56:78:9A

#My ip address (must NOT be same for nodes, you know why).

IPADD=10.0.1.15

NETMASK=255.255.255.0

#If you need help.

if [ “$1” = “—help” ]; then

  echo “[start](default) or [stop]”

  echo “your network devices:”

  lspci|grep -i net

  exit

fi

NETWORKMANAGER=”service network-manager”

#Some distributions have like this.

#NETWORKMANAGER=”/etc/init.d/network-manager”

#Check whether you have root permissions or not.

if [ “$(whoami &2>/dev/null)” != “root” ] && [ “$(id -un &2>/dev/null)” != “root” ] ; then

  echo “Oops you must be root to run this script!”; exit 1

fi

if [ “$1” = “stop” ]; then

  echo “Resuming normal networking...”

  echo “Restarting network-manager...”

  $NETWORKMANAGER restart

  echo “turning wlan iface off”

  batctl if del $IFACE

  sleep 10

  echo “OK”

  echo “It can take a few minutes until network-manager gets a new route”

  echo

  exit

elif [ “$1” = “restart” ]; then

  echo “Not implemented. Call this script first with stop and then with start”

  exit

else # “start”

  echo “Stopping network-manager…”

  $NETWORKMANAGER stop

  echo “plz wait…”

  sleep 10

  echo “Turning 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 $ESSID ap $CELLID channel $CHANNEL

  echo “Loading module into kernel”

  modprobe batman-adv

  echo “Adding iface to batman”

  batctl if add $IFACE

  echo “Turning wlan iface on”

  ifconfig $IFACE up

  echo “Turning batman iface on”

  ifconfig bat0 $IPADD netmask $NETMASK up

  echo “ESSID $ESSID on $IFACE should be ready”

  echo “Now B.A.T.M.A.N. is up and running successfully !”

  echo "To resume normal networking call this script with option stop"

  echo

fi

Now it’s running. You can see batman is flying over your head. Ha Ha Ha…

If you type “dmesg” you see some packets are sending time to time. Or you can monitor those packets (DHCP REQUESTS) via wireshark. Try that also.

And you can check current connected nodes using this command,

batctl o

If you have connected to other nodes try to ping to those nodes. If you do so your network is established.

Here is some additional but useful part by using B.A.T.M.A.N. protocol.

If one node has internet connectivity you can share it among others. Yes other nodes can access internet through that internet node. By using this commands,

dhclient bat0

So if have any unexpected errors, please informed me.\m/
