30 Ott 14 WPA2 connection without NetworkManager in Debian linux

This is a memo that I can use to remember how to enable WPA2 protected WiFI connections with debian without using NetworkManager.

All that you have to do is:

• create the file /etc/wpa_supplicant/wpa_supplicant.conf with the following content:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=0
country=IT
ap_scan=2

network={
ssid=”My WiFI SSID”
psk=”mysupersecret password”
bssid=””
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=TKIP
}

• if you want to set a static IP, add the following content to the file /etc/network/interfaces

iface wlan0 inet static
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
address 192.168.100.7
netmask 255.255.255.0
network 192.168.100.0
broadcast 192.168.100.255

• if, instead, you want a dynamic address assigned by a DHCP server, add the following to /etc/network/interfaces

iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

• now, setup the connection with this command by root (sudo before the command if you are on ubuntu):

ifup wlan0

• when you have finisched with the connection, close it up with the command by root (sudo before the command if you are on ubuntu)

ifdown wlan0
