WiFi
and WPA-PSK on Debian:
by
Francesco Palmisano
If you have a wireless LAN in your home, maybe you need to protect your
pravacy from connections abuses.
There are different ways to protect your WiFi LAN: one is to use WEP
encrypt key, but it's a easy crackable metod!
A second way is to use a WPA or WPA2 encrypt key.
In this tutorial we let see how to use WPA key to protect your WiFi LAN.
Let's go:
First of all install a wpa
demon with your favourite packages manager (as
Synaptic):
wpasupplicant
Now you need to create a configuration file in /etc/ folder
So, with a text editor create a file called wpa_supplicant.conf
(or download ones here),
like this:
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="insert your
wireless net name"
psk="insert your
exadecimal key "
key_mgmt=WPA-PSK
proto=WPA
pairwise=TKIP
group=TKIP
}
The exadecimal key has to be the same present in your ruter or
acess-point.
Now modify the file
/etc/network/interfaces.
from this (or sometihng similar, you could use DHCP instaed of a static
address):
auto wlan0
iface wlan0 inet static
address "static adress"
netmask 255.255.255.0
wireless-essid "nome of
your wifi lan"
broadcast "static adress"
gateway "static adress"
# dns-* options are
implemented by the resolvconf package, if installed
dns-nameservers "static
adress"
to this:
auto wlan0
iface wlan0 inet static
address "static adress"
netmask 255.255.255.0
wireless-essid "nome of
your wifi lan"
broadcast "static adress"
gateway "static adress"
# dns-* options are
implemented by the resolvconf package, if installed
dns-nameservers "static adress"
pre-up wpa_supplicant
-Bw -Dwext -i wlan0 -c/etc/wpa_supplicant.conf
post-down killall -q
wpa_supplicant
Your wireless device could be different from
"wlan0" , so control your device name (as root) with this command:
iwconfig
And now restart your network service (as root):
/etc/init.d/networking
restart
Now your WiFi LAN is encrypt with WPA way, enjoy it!!
