debian wlan0 wpa/psk

1.添加wpa-psk支持，在debian下是这个插件wpasupplicant

apt-get install wpasupplicant

可查看debian wiki

[code]

2.修改/etc/network/interfaces项，如下: 

[code]
  
iface wlan0 inet dhcp
  
wpa-driver wext
  
wpa-ssid DFERG
  
wpa-proto WPA
  
wpa-pairwise TKIP
  
wpa-group TKIP
  
wpa-key-mgmt WPA-PSK
  
wpa-psk fcb3717c5f66e893d9010a6872436b34686618a3e8fa2833d56bb98b41be5c8d

3.最关键的WPA－PSK项，之前一直无法连接，经google，原来此处不能写入明文密码，需要通过wpa-passphrase转换的，如下:

[code]

wpa_passphrase <your_essid> <your_assic_key>

例如:

```bash
  
wpa_passphrase DFERG 100200300b
  
network={
  
ssid="DFERG"
  
#psk="100200300b"
  
psk=fcb3717c5f66e893d9010a6872436b34686618a3e8fa2833d56bb98b41be5c8d
  
}
