OLSR - di Ubuntu
Sumber: http://wmunguiam.blogspot.com/2009/01/olsr-over-ubuntu-804.html
Pada dasarnya ada dua (2) cara utk mengaktifkan OLSR di Ubuntu
- Install dari repository
- Compile dari source code
Instalasi OLSRD dari repository
OLSR dapat di instalasi langsung menggunakan perintah
sudo apt-get install olsrd olsrd-plugins
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

========= 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
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 10.10.10.11 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
6.-Restart services: networking and OLSR wmunguiam@server:~$ sudo /etc/init.d/network restart wmunguiam@server:~$ sudo /etc/init.d/olsrd start
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.
7.-Verify services
