Koneksi Wifi Menggunakan wpa_supplicant (Linux)

Pertama buat dulu settingannya di /etc/wpa_supplicant.conf

# cat << EOF >> /etc/wpa_supplicant.conf

> network={

> scan_ssid=1

> ssid="ISIKAN_NAMA_SSIDNYA_DISINI"

> key_mgmt=WPA-PSK

> psk="ISIKAN_PASSWORDNYA_DISINI"

> }

> EOF



Kemudian aktifkan interface wifinya, biasanya di linux menggunakan wlan0 atau eth1.

# ifconfig eth1 up


Jalankan wpa_supplicant sebagai daemon menggunakan konfigurasi tadi.

# wpa_supplicant -B -ieth1 -c/etc/wpa_supplicant.conf


Untuk mendapatkan IP kita bisa menggunakan dhcpcd atau dhclient, disini kita coba menggunakan dhcpcd

# dhcpcd eth1

dhcpcd[6088]: version 5.2.12 starting

dhcpcd[6088]: eth1: broadcasting for a lease

dhcpcd[6088]: eth1: offered 192.168.*.* from 192.168.*.*

dhcpcd[6088]: eth1: ignoring offer of 192.168.*.* from 192.168.*.*

dhcpcd[6088]: eth1: acknowledged 192.168.*.* from 192.168.*.*

dhcpcd[6088]: eth1: checking for 192.168.*.*

dhcpcd[6088]: eth1: leased 192.168.*.* for 86400 seconds

dhcpcd[6088]: forked to background, child pid 6124




Agar internetan lebih cepet, kita bisa setting dns. Biasanya sih saya pake punya google, kita setting nya di /etc/resolv.conf.

# echo -ne "nameserver 8.8.8.8\nnameserver 8.8.4.4" > /etc/resolv.conf


Coba cek koneksinya berhasil apa tidak dengan ping ke url mana saja, contoh saya ping ke google

# ping -c 3 www.google.co.id

PING www.l.google.com (74.125.*.*) 56(84) bytes of data.

Oh yaa saya sekalian kasih bash scriptnya untuk koneksi manual maupun wpa di linux nih, silahkan di coba sekalian di review :)
