Pada dasarnya ada dua (2) cara utk mengaktifkan OLSR di Ubuntu, yaitu

Install dari repository
Compile dari source code

Instalasi OLSRD dari repository

OLSR dapat di instalasi langsung dari repository menggunakan perintah

sudo apt-get install olsrd olsrd-plugins

hanya saja ini biasanya bukan versi bleeding edge :)

Compile dari Source Code

Siapkan aplikasi pendukung

sudo apt-get install kernel-package libncurses5-dev fakeroot wget \
bzip2 g++ libssl-dev libxml2-dev doxygen bison flex libc6

Download source code dari

http://www.olsr.org/?q=download

Copy, Extract dan Compile

cp olsrd-0.6.2.tar.bz2 /usr/local/src/
cd /usr/local/src
tar jxvf olsrd-0.6.2.tar.bz2 
cd /usr/local/src/olsrd-0.6.2
make all
make install

Sedikir catatan tentang olsrd

========= C O N F I G U R A T I O N - F I L E ============
olsrd uses the configfile /etc/olsrd.conf
a default configfile. A sample RFC-compliance aimed
configfile can be found in olsrd.conf.default.rfc.
However none of the larger OLSRD using networks use that
so install a configfile with activated link quality exstensions
per default.
can be found at files/olsrd.conf.default.lq
==========================================================

Edit OLSRD.CONF

Edit olsrd.conf

sudo cp /etc/olsrd.conf /etc/olsrd.conf.original
sudo vi /etc/olsrd.conf

Contoh konfigurasi sederhana

InterfaceDefaults {
    Ip4Broadcast      255.255.255.255
}
Interface "eth1" {
   # Ip4Broadcast 255.255.255.255
   # Ip6AddrType site-local
   # Ip6MulticastSite ff05::11
   # Ip6MulticastGlobal ff0e::1

   HelloInterval 6.0
   HelloValidityTime 600.0
   TcInterval 0.5
   TcValidityTime 300.0
   MidInterval 10.0
   MidValidityTime 300.0
   HnaInterval 10.0
   HnaValidityTime 300.0
   # Weight 0
   # LinkQualityMult 192.168.0.1 0.5

Edit Interface

Kita dapat melakukannya menggunakan

iwconfig di console
edit /etc/network/interface

Dengan asumsi eth1 adalah interface wireless. Edit di console

iwconfig eth1 mode ad-hoc
iwconfig eth1 essid MESH
iwconfig eth1 ap 02:ca:ff:ee:ba:be
iwconfig eth1 channel 1
ifconfig eth1 172.16.1.2
ifconfig eth1 netmask 255.255.0.0

atau

iwconfig eth1 mode ad-hoc essid MESH ap 02:ca:ff:ee:ba:be channel 1
ifconfig eth1 172.16.1.2 netmask 255.255.0.0

Edit

vi /etc/network/interfaces

Isi kira-kira sebagi berikut

   auto lo
   iface lo inet loopback

   auto eth1
   allow-hot plug eth1
   iface eth1 inet static
   address 172.16.1.2
   broadcast 172.16.255.255
   netmask 255.255.0.0
   wireless-mode ad-hoc
   wireless-channel 1
   wireless-essid MESH
   wireless-bssid 02:ca:ff:ee:ba:be

   auto wlan0
   allow-hot plug wlan0
   iface wlan0 inet static
   address 10.10.10.11
   netmask 255.255.255.0
   wireless-mode ad-hoc
   wireless-channel 11
   wireless-key s:12345
   wireless-essid mesh

   #auto eth0
   #iface eth0 inet dhcp

Restart Networking

networking and OLSR

sudo /etc/init.d/networking restart
sudo /etc/init.d/olsrd start

Jika kita mengcompile OLSR lakukan

sudo olsrd -d 2

OBS: If you get this: wmunguiam@server:~$ sudo /etc/init.d/network restart

   Error for wireless request "Set Mode" (8B06) :
   SET failed on device wlan0 ; Invalid argument.
   Error for wireless request "Set Mode" (8B06) :
   SET failed on device wlan0 ; Device or resource busy.

Means your wireless Interface (Hardware) does not support working on Ad-hoc mode. You have to use (recommended) an USB Wireless Card.

Verifikasi Jaringan

Asumsinya eth1 adalah interface WLAN.

ifconfig eth1

eth1      Link encap:Ethernet  HWaddr 00:21:00:50:a3:90  
          inet addr:172.16.1.2  Bcast:172.16.255.255  Mask:255.255.0.0
          inet6 addr: fe80::221:ff:fe50:a390/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:52 errors:0 dropped:0 overruns:0 frame:188
          TX packets:88 errors:11 dropped:0 overruns:0 carrier:0

          RX bytes:3356 (3.3 KB)  TX bytes:14387 (14.3 KB)
          Interrupt:17

Cek wireless

iwconfig eth1

eth1      IEEE 802.11bg  ESSID:"MESH"

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Cek Routing

netstat -nr
