如何在 OpenWrt 10.03 中获取已连接 wifi 客户端的列表？

Answer 1

为了查看关联的 wifi 客户端，即使它们没有 DHCP 客户端或没有 ip，您也必须向 AP 询问关联的 wifi 设备：

# Universal (Tested with OpenWRT 14.07 and 15.05.X)
iwinfo wlan0/wl0/ath0 assoclist

# Proprietary Broadcom (wl)
wl -i wl0 assoclist

# Proprietary Atheros (madwifi)
wlanconfig ath0 list sta

# MAC80211
iw dev wlan0 station dump

这样，您还将看到连接速度。对我来说，这看起来像这样：

# iwinfo wlan0 assoclist
12:34:56:78:9A:BC  -26 dBm / -95 dBm (SNR 69)  1930 ms ago
RX: 24.0 MBit/s, MCS 0, 20MHz                   3359 Pkts.
TX: 130.0 MBit/s, MCS 14, 20MHz, short GI       1209 Pkts.

Answer 2

You may use the arp-table, or DHCP-leases. Not a perfect solution, maybe it's enough?

List arp-table

arp

List DHCP-leases

cat /tmp/dhcp.leases

... and combined

for ip in $(arp | grep -v IP | awk '{print $1}'); do 
    grep $ip /tmp/dhcp.leases; 
done
