Pada dasarnya ada dua (2) cara utk mengaktifkan [[OLSR]] di [[Ubuntu]], yaitu
  
−
1.- Get information
+
* Install dari repository
−
http://www.olsr.org/?q=download
+
* Compile dari [[source code]]
  
−
2.- Get OLSR package
+
==Instalasi OLSRD dari repository==
−
Visit: http://packages.ubuntu.com/search?keywords=olsrd
 
  
−
3.- Install OLSR daemon (and dependecies: libc6 bison flex)
+
[[OLSR]] dapat di instalasi langsung dari [[repository]] menggunakan perintah
−
wmunguiam@server:~$ sudo apt-get install olsrd olsrd-plugins
 
  
−
If you download lastest olsr package, install it by going to olsrd dowloaded directory, uncompress it and:
+
sudo apt-get install olsrd olsrd-plugins
−
wmunguiam@server:~$ make
 
−
wmunguiam@server:~$ sudo make install
 
  
−
4.-Edit /etc/olsrd/olsrd.conf as below as example (Modify if you need)
+
hanya saja ini biasanya bukan versi bleeding edge :)
−
wmunguiam@server:~$ sudo cp /etc/olsrd/olsrd.conf /etc/olsrd/olsrd.conf.original
+
tapi lumayan stabil lah untuk ngoprek.
−
wmunguiam@server:~$ sudo vim /etc/olsrd/olsrd.conf
 
  
−
    DebugLevel 1
+
Masalah dengan olsrd hasil apt-get adalah
−
    Interface "wlan1"
+
 
−
    {
+
* olsrd dengan /etc/init.d/olsrd mencari /etc/olsrd.conf bukan /etc/olsrd/olsrd.conf. Akibatnya akan abort karena tidak menemukan file konfigurasi.
 +
* olsrd akan melaporan error, buang LinkQualityDijkstraLimit dan LinkQualityWinSize di olsrd.conf. Caranya edit
 +
 
 +
vi /etc/olsrd.conf

Sedikit 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
 +
==========================================================
 +
mkdir -p /etc
 +
cp -i files/olsrd.conf.default.lq /etc/olsrd.conf
 +
-------------------------------------------
 +

==Edit OLSRD.CONF==
 +
 
 +
Edit olsrd.conf
 +
 
 +
sudo cp /etc/olsrd.conf /etc/olsrd.conf.original
 +
sudo vi /etc/olsrd.conf
 +
 
 +
Pastikan ada interface yang aktif menggunakan OLSR, misalnya eth1, wlan0 dll.
 +
Contoh konfigurasi sederhana
 +
 
 +
InterfaceDefaults {
 +
    Ip4Broadcast      255.255.255.255
 +
}
 +
Interface "eth1" {

5.-Edit linux network interface(s) to work as Ad-hoc node
+
Kadang kala pada saat kita jalankan olsrd akan melaporan error, buang LinkQualityDijkstraLimit dan LinkQualityWinSize di olsrd.conf. Caranya edit
−
wmunguiam@server:~$ sudo vim /etc/network/interfaces
+
 
 +
vi /etc/olsrd.conf
 +
 
 +
Remark line 124
 +
 
 +

 +
 
 +
Remark line 240
 +
 
 +
# LinkQualityWinSize    100
 +
 
 +
==Cek konfigurasi==
 +
 
 +
Sebaiknya cek konfigurasi menggunakan perintah
 +
 
 +
sudo olsrd -d 2
 +
 
 +
atau bagi yang menginstall menggunakan apt-get bisa
 +
 
 +
sudo olsrd -d 2 -f /etc/olsrd/olsrd.conf
 +
 
 +
Kayanya menggunakan apt-get ada beberapa error, di beri # aja di line yang error. Biasanya setelah di # error yang ada maka olsrd akan jalan.
 +
 
 +
===IPv6===
 +
 
 +
Menjalankan OLSR Untuk IPv6
 +
 
 +
sudo olsrd -d 2 -ipv6
 +
 
 +
==Edit Interface==
 +
 
 +
Kita dapat melakukannya menggunakan
 +
 
 +
* iwconfig di console

 +
Edit di console

Sumber: http://wmunguiam.blogspot.com/2009/01/olsr-over-ubuntu-804.html

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

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 :) tapi lumayan stabil lah untuk ngoprek.

Masalah dengan olsrd hasil apt-get adalah

  • olsrd dengan /etc/init.d/olsrd mencari /etc/olsrd.conf bukan /etc/olsrd/olsrd.conf. Akibatnya akan abort karena tidak menemukan file konfigurasi.
  • olsrd akan melaporan error, buang LinkQualityDijkstraLimit dan LinkQualityWinSize di olsrd.conf. Caranya edit
vi /etc/olsrd.conf

Remark line 124 

# LinkQualityDijkstraLimit 3 3.0

Remark line 240 

# LinkQualityWinSize    100

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/mediawiki/index.php/Releases

Copy, Extract dan Compile 

wget http://www.olsr.org/releases/0.9/olsrd-0.9.0.2.tar.bz2
cp olsrd-0.9.0.2.tar.bz2 /usr/local/src/
cd /usr/local/src
tar jxvf olsrd-0.9.0.2.tar.bz2 
cd /usr/local/src/olsrd-0.9.0.2
make all
make install
make libs
make install_libs
mkdir -p /etc
cp -i files/olsrd.conf.default.lq /etc/olsrd.conf

Sedikit 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

-------------------------------------------
Edit /etc/olsrd.conf before running olsrd!!
-

Edit OLSRD.CONF

Edit olsrd.conf 

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

Pastikan ada interface yang aktif menggunakan OLSR, misalnya eth1, wlan0 dll. 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

Tambahkan untuk Plugin txtinfo 

LoadPlugin "olsrd_txtinfo.so.0.1"
   {
   PlParam "port" "8080"
   PlParam "Host" "127.0.0.1"
   # PlParam "Net" "0.0.0.0 0.0.0.0"
   # PlParam "Host" "80.23.53.22"
   # # PlParam "Net" "192.168.0.0 255.255.0.0"  
   }


Kadang kala pada saat kita jalankan olsrd akan melaporan error, buang LinkQualityDijkstraLimit dan LinkQualityWinSize di olsrd.conf. Caranya edit 

vi /etc/olsrd.conf

Remark line 124 

# LinkQualityDijkstraLimit 3 3.0

Remark line 240 

# LinkQualityWinSize    100

Cek konfigurasi

Sebaiknya cek konfigurasi menggunakan perintah 

sudo olsrd -d 2

atau bagi yang menginstall menggunakan apt-get bisa 

sudo olsrd -d 2 -f /etc/olsrd/olsrd.conf

Kayanya menggunakan apt-get ada beberapa error, di beri # aja di line yang error. Biasanya setelah di # error yang ada maka olsrd akan jalan.

IPv6

Menjalankan OLSR Untuk IPv6 

sudo olsrd -d 2 -ipv6

Edit Interface

Kita dapat melakukannya menggunakan

  • iwconfig di console
  • edit /etc/network/interface

Dengan asumsi eth1 adalah interface wireless. Edit di console 

iwconfig wlan0 mode ad-hoc
iwconfig wlan0 essid MESH
iwconfig wlan0 ap 02:ca:ff:ee:ba:be
iwconfig wlan0 channel 1
ifconfig wlan0 10.1.1.1
ifconfig wlan0 netmask 255.0.0.0

atau 

iwconfig wlan0 mode ad-hoc essid MESH ap 02:ca:ff:ee:ba:be channel 1
ifconfig wlan0 10.1.1.1 netmask 255.0.0.0


Edit 

vi /etc/network/interfaces

Isi kira-kira sebagi berikut 

   auto lo
   iface lo inet loopback

   auto wlan0
   allow-hot plug wlan0
   iface wlan0 inet static
   address 10.1.1.1
   broadcast 10.255.255.255
   netmask 255.0.0.0
   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
   
   # Konfigurasi IPv6
   iface wlan0 inet6 static
   address 2001:123:127::127
   netmask 128
   wireless-mode ad-hoc
   wireless-channel 1
   wireless-essid MESH
   wireless-bssid 02:ca:ff:ee:ba:be

Restart Networking

networking and OLSR 

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


Jika pada saat melakukan 

sudo /etc/init.d/network restart

Keluar error berikut 

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.

Kemungkinan wireless interface / hardware yang anda gunakan tidak mendukung mode ad-hoc. Kita perlu menggunakan USB wireless card lain.

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

Cek wireless 

iwconfig eth1

Cek Routing 

netstat -nr

Perhatikan host dengan netmask 255.255.255.255, ini merupakan host yang di tambahkan secara automatis oleh OLSR.
