Ist eine Variante wie die WLAN-Netzwerke konfiguriert werden können. Im Vergleich zum Networkmanager u.a. unter Gnome (Paket gnome-network-manager) ist dies weniger Fehleranfällig und leichter direkt aus dem Terminal konfigurierbar.

=== Installation ===
|
||
|
|
|
||
|
|
==== Debian ====
|
||
|
|
|
||
|
|
1. Paket installieren
|
||
|
|
|
||
|
|
<source lang=bash>
|
||
|
|
sudo apt-get update
|
||
|
|
sudo apt-get install wpasupplicant
|
||
|
|
</source>
|
||
|
|
|
||
|
|
2. Rechte auf Interfaces beschränken
|
||
|
|
|
||
|
|
<source lang=bash>
|
||
|
|
sudo chmod 0600 /etc/network/interfaces
|
||
|
|
</source>
|
||
|
|
|
||
|
|
3. Interfaces prüfen
|
||
|
|
|
||
|
|
<source lang=bash>
|
||
|
|
cat /etc/network/interfaces
|
||
|
|
</source>
|
||
|
|
|
||
|
|
oder setzen:
|
||
|
|
|
||
|
|
<source lang=bash>
|
||
|
|
sudo cat >/etc/network/interfaces<<EOF
|
||
|
|
# The loopback network interface
|
||
|
|
auto lo
|
||
|
|
iface lo inet loopback
|
||
|
|
|
||
|
|
auto wlan0
|
||
|
|
iface wlan0 inet dhcp
|
||
|
|
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
|
||
|
|
EOF
|
||
|
|
</source>
|
||
|
|
|
||
|
|
4. Offenes WLAN konfigurieren
|
||
|
|
|
||
|
|
erstmal ansehen:
|
||
|
|
|
||
|
|
<source lang=bash>
|
||
|
|
cat /etc/wpa_supplicant/wpa_supplicant.conf
|
||
|
|
</source>
|
||
|
|
|
||
|
|
die Datei kann so zum freien WLAN im HQ führen:
|
||
|
|
|
||
|
|
<source lang=bash>
|
||
|
|
cat >/etc/wpa_supplicant/wpa_supplicant.conf<<EOF
|
||
|
|
### ### ### C3D2 ### ### ###
|
||
|
|
network={
|
||
|
|
ssid="C3D2"
|
||
|
|
key_mgmt=NONE
|
||
|
|
priority=0
|
||
|
|
}
|
||
|
|
### ### ### C3D2 ### ### ###
|
||
|
|
EOF
|
||
|
|
</source>
|
||
|
|
|
||
|
|
5. Passwortgecshütztes WLAN konfigurieren
|
||
|
|
|
||
|
|
mit wpa_passphrase am Bsp. [[C3D2-fallback]] als Einzeiler:
|
||
|
|
|
||
|
|
<source lang=bash>
|
||
|
|
wpa_passphrase C3D2-fallback >> /etc/wpa_supplicant/wpa_supplicant.conf
|
||
|
|
</source>
|
||
|
|
|
||
|
|
mit <code>wpa_cli</code> (nähere Erläuterung s. Quelle)
|
||
|
|
<pre>scan
|
||
|
|
scan_results
|
||
|
|
add_network
|
||
|
|
set_network 0 ssid "WLAN-Network"
|
||
|
|
set_network 0 psk "SupahSecretPassphrase"</pre>
