wpa_supplicant 無法從配置文件中設置 essid 和其他參數

  • August 9, 2015

我無法使用 wpa_supplicant 在無線介面上設置 essid 和其他參數。

使用 -Dwext 拋出ioctl[SIOCSIWENCODEEXT]

$ sudo wpa_supplicant -B -i wlan0 -Dwext -c universitywpa 
Successfully initialized wpa_supplicant
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument

並且也無法設置 ESSID：

$ iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:off/any  
         Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
         Tx-Power=15 dBm   
         Retry short limit:7   RTS thr:off   Fragment thr:off
         Power Management:off

如果我使用-Dnl80211，則不會引發 IOCTL 錯誤：

$ sudo wpa_supplicant -B -i wlan0 -Dnl80211 -c universitywpa 
Successfully initialized wpa_supplicant

但是 ESSID 仍然關閉/任何：

$ iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:off/any  
         Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
         Tx-Power=15 dBm   
         Retry short limit:7   RTS thr:off   Fragment thr:off
         Power Management:off

我使用 -d （詳細）執行相同的命令以查看可能發生的情況：

$ sudo wpa_supplicant -B -i wlan0 -Dnl80211 -c universitywpa -d

但我不確定如何解釋這一點。

為什麼沒有設置 ESSID？

如果我手動執行 iwconfig，我可以設置 ESSID：

sudo iwconfig wlan0 essid UNIVERSITY-SECURE
$ iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:"UNIVERSITY-SECURE"  
         Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
         Tx-Power=15 dBm   
         Retry short limit:7   RTS thr:off   Fragment thr:off
         Power Management:off

$

但顯然，要使連接正常工作，需要的不僅僅是 ESSID。

大學wpa的內容：

network={
   ssid="UNIVERSITY-SECURE"
   scan_ssid=1
   key_mgmt=WPA-EAP
   pairwise=CCMP TKIP
   group=CCMP TKIP
   eap=PEAP
   identity="my-user"
   password="mypass"
   ca_cert="university_comodo_cert.pem"
   phase1="peapver=0"
   phase2="MSCHAPV2"
}

我已經使用這些設置在其他機器上連接而沒有問題。但我一直使用-Dwext，從不使用-Dnl80211。

lshw無線介面：

司機是iwlwifi。

這是 iwlwifi 和 -Dnl80211 之間的問題嗎？如何進一步診斷此問題？

我最終刪除了 -B （在後台執行守護程序）

sudo wpa_supplicant -i wlan0 -c wpaconfig -D nl80211,wext

並意識到我的腳本沒有等待連接完成：

wlan0: CTRL-EVENT-CONNECTED - Connection to 00:11:22:33:44:55 completed [id=0 id_str=]

並且由於沒有看到 essid 而提前中止。似乎沒有選項可以wpa_supplicant僅在 CTRL-EVENT-CONNECTED 時以程式方式要求對自身進行守護，因此我可能不得不為此使用期望腳本。
