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, 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
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.
