Wifi
如何為我的 wifi 熱點添加 IE 欄位?
是否可以將 IE 欄位附加到我的 wifi 熱點,以便它出現在
iwlist
掃描它的其他機器的輸出中?例子:
- 我選擇
1234567891011121314151617181920
成為我的 wifi 熱點(MAC 地址11:22:33:44:55:66
)的附加欄位- 使用者使用命令掃描我的 wifi 熱點
iwlist wlan0 scan
,應該給出輸出:wlan0 Scan completed : Cell 01 - Address: 11:22:33:44:55:66 [...] IE: Unknown 1234567891011121314151617181920 [...]
IE 代表資訊元素。它們作為信標幀的一部分傳輸,並攜帶各種資訊,例如 SSID、支持的速率等。

其中一些資訊元素是特定於供應商的,這意味著它們可能會被其他供應商忽略。保留意味著它將來可能具有標準含義,實際上其中一些已經具有。(我正在查看一個舊標準。)您可以在hostapd.conf中配置它們
# Additional vendor specific elements for Beacon and Probe Response frames # This parameter can be used to add additional vendor specific element(s) into # the end of the Beacon and Probe Response frames. The format for these # element(s) is a hexdump of the raw information elements (id+len+payload for # one or more elements) vendor_elements=dd0411223301
十六進制數據具有以下結構:
Element ID 應為 dd,OUI 是IEEE分配的 3 字節數字,但好消息是 iwlist 將所有這些都顯示為未知,除了 WPA (0050f2) 和 WPA2 (000fac)。
