Question

嘿，我在 WRT1900ac linksy 的启动时运行了以下 BASH脚本：

USER="admin"
PASS="passhere"
PROTOCOL="http"
ROUTER_IP="192.168.1.1"

# Port to connect to which will provide the JSON data.
PORT=9898

while [ 1 ]
do
    # Grab connected device MAC addresses through router status page.
    MACS=$(curl -s --user $USER:$PASS $PROTOCOL://$ROUTER_IP/Status_Wireless.live.asp)

    # clear temp JSON file
    echo > temp.log

    # Get hostname and IP (just in case there is no hostname).
    for MAC in $(echo $MACS | grep -oE "wl_mac::[a-z0-9]{2}:[a-z0-9]{2}:[a-z0-9]{2}:[a-z0-9]{2}:[a-z0-9]{2}:[a-z0-9]{2}" | cut -c 9-);
    do
        grep 0x /proc/net/arp | awk '{print $1 " " $4}' | while IFS= read -r line
        do
        IP=$(echo $line | cut -d' ' -f1)
        MACTEMP=$(echo $line | cut -d' ' -f2)
        HOST=$(arp -a | grep $IP | cut -d' ' -f1)

        # if no hostname exists, just use IP.
        if [ "$HOST" == "" ]
        then
            HOST=$IP
        fi

        if [ "$MAC" == "$MACTEMP" ]
        then
            JSON="{'hostname' : '$HOST', 'mac_address' : '$MAC'}"
            echo $JSON >> temp.log
        fi

        done
    done

    # Provide the JSON formatted output on $PORT of router.
    # This allows one connection before closing the port (connect, receive data, close).
    # Port will reopen every 5 minutes with new data as setup in a cron job.
    echo -e "HTTP/1.1 200 OK\n\n $(cat temp.log)" | nc -l -p$PORT >/dev/null

    # Wait for 10 seconds and do it all over.
    sleep 10

done

由于某些原因，当我重新启动路由器然后尝试访问 http://192.168.1.1:9898 时，它只显示一个空白页，即使我将我的Android手机通过wifi连接到路由器并且路由器在状态页面上显示MAC地址。

应在该页面上的内容是当前连接到路由器并以 JSON 形式显示的所有无线MAC地址。

任何 BASH 大师在这里可以帮助发现问题吗？

我认为应该是

echo -e "HTTP/1.1 200 OK\n\n $(cat temp.log)" | nc -l -p$PORT 0.0.0.0 >/dev/null

启动时出现DD-WRT Bash脚本
