OpenWrt 日志记录:如何找出“wifi 取消认证”

OpenWrt 日志记录:如何找出“wifi 取消认证”

如果有人开始使用 wifi,我可以通过 logread 看到:

Jan 23 21:04:47 router daemon.info hostapd: wlan0: STA XX:XX:XX:XX:XX:XX IEEE 802.11: authenticated

但我怎么才能看到他/她断开了连接?logread 中没有“bla-bla deauthenticated bla”行,甚至没有指向某人断开连接的内容。

我尝试谷歌搜索:
http://wiki.openwrt.org/doc/uci/system
但它没有写日志级别。

有人能帮我找出如何找出有人断开了路由器的 wifi 连接吗?当有人断开连接时,日志读取甚至没有写一行。

请帮忙!!这很重要!
谢谢!:\

您可以使用以下命令之一轮询关联客户端的列表:

  • iw dev wlan0 station dump--> 对于nl80211/mac80211兼容的驱动程序

  • wlc assoclist--> 对于专有broadcom-wl驱动程序

  • iwinfo wlan0 assoclist--> 用于主干libiwinfo中可用的抽象OpenWrt

从你的日志来看,hostapd第一个应该有效。示例输出:

   root@OpenWrt ~ # iw dev wlan0 station dump
   Station 00:13:02:xx:xx:xx (on wlan0)
      inactive time:    0 ms
      rx bytes: 21835
      rx packets:   152
      tx bytes: 19772
      tx packets:   100
      tx retries:   6
      tx failed:    0
      signal:   -43 dBm
      signal avg:   -44 dBm
      tx bitrate:   36.0 MBit/s

此外,hostapd 还会报告断开连接(例如,如果从命令行运行 - 肯定有办法将其放入日志中):

root@OpenWrt ~ # hostapd -P /var/run/wifi-phy0.pid /var/run/hostapd-phy0.conf
Using interface wlan0 with hwaddr 94:0c:6d:xx:xx:xx and ssid 'marvin'
wlan0: STA 00:13:02:xx:xx:xx IEEE 802.11: authenticated
wlan0: STA 00:13:02:xx:xx:xx IEEE 802.11: associated (aid 1)
AP-STA-CONNECTED 00:13:02:xx:xx:xx
wlan0: STA 00:13:02:xx:xx:xx WPA: pairwise key handshake completed (RSN)
(...)
AP-STA-DISCONNECTED 00:13:02:xx:xx:xx

hostapd或者,您也可以使用以下方法通过其控制插座进行连接wpa-cli

root@OpenWrt ~ # wpa_cli -p /var/run/hostapd-phy0       
wpa_cli v0.8.x
