确认路由器固件版本 ​

本教程是在稳定版1.0.68操作的，如果发现不能解锁SSH，请将固件版本刷为1.0.68再尝试。

获取小米路由器stok ​

如上图所示，登陆小米路由器后台，在浏览器的地址栏中获取stok并记录，stok为地址中蓝色部分

开启小米路由器SSH端口 ​

将下面代码的stok=xxx替换为上一步获取的stok值

bat
curl -X POST http://192.168.31.1/cgi-bin/luci/;stok=xxx/api/xqsystem/start_binding -d "uid=1234&key=1234'%0Anvram%20set%20ssh_en%3D1'"

curl -X POST http://192.168.31.1/cgi-bin/luci/;stok=xxx/api/xqsystem/start_binding -d "uid=1234&key=1234'%0Anvram%20commit'"

curl -X POST http://192.168.31.1/cgi-bin/luci/;stok=xxx/api/xqsystem/start_binding -d "uid=1234&key=1234'%0Ased%20-i%20's%2Fchannel%3D.*%2Fchannel%3D%22debug%22%2Fg'%20%2Fetc%2Finit.d%2Fdropbear'"

curl -X POST http://192.168.31.1/cgi-bin/luci/;stok=xxx/api/xqsystem/start_binding -d "uid=1234&key=1234'%0A%2Fetc%2Finit.d%2Fdropbear%20start'"

打开cmd或terminal，复制上面的代码，然后一行一行的执行，如果返回{"code":0}，则表示操作成功

text
{"hw":"RD15","sync":false,"code":0,"rtid":"08a62ca2-2142-efca-d6f7-9f0b03628d88","did":"771786011"}

SSH登录路由器 ​

用户名为root，密码需要使用SN计算，小米路由器密码计算器

bash
ssh root@192.168.31.1

固化SSH ​

确保路由器重启和升级后还能再使用SSH

固化ssh，ssh登录路由器后，执行以下代码

bash
nvram set ssh_en=1
nvram set telnet_en=1
nvram set uart_en=1
nvram set boot_wait=on
nvram commit

永久开启ssh，重启不会关闭

将以下代码保存到 /data/auto_ssh/auto_ssh.sh

bash
#!/bin/sh

auto_ssh_dir="/data/auto_ssh"
host_key="/etc/dropbear/dropbear_rsa_host_key"
host_key_bk="${auto_ssh_dir}/dropbear_rsa_host_key"

unlock() {
    # Restore the host key.
    [ -f $host_key_bk ] && ln -sf $host_key_bk $host_key

    # Enable telnet, ssh, uart and boot_wait.
    [ "$(nvram get telnet_en)" = 0 ] && nvram set telnet_en=1 && nvram commit
    [ "$(nvram get ssh_en)" = 0 ] && nvram set ssh_en=1 && nvram commit
    [ "$(nvram get uart_en)" = 0 ] && nvram set uart_en=1 && nvram commit
    [ "$(nvram get boot_wait)" = "off" ]  && nvram set boot_wait=on && nvram commit

    [ "`uci -c /usr/share/xiaoqiang get xiaoqiang_version.version.CHANNEL`" != 'stable' ] && {
        uci -c /usr/share/xiaoqiang set xiaoqiang_version.version.CHANNEL='stable' 
        uci -c /usr/share/xiaoqiang commit xiaoqiang_version.version 2>/dev/null
    }

    channel=`/sbin/uci get /usr/share/xiaoqiang/xiaoqiang_version.version.CHANNEL`
    if [ "$channel" = "release" ]; then
        sed -i 's/channel=.*/channel="debug"/g' /etc/init.d/dropbear
    fi

    if [ -z "$(pidof dropbear)" -o -z "$(netstat -ntul | grep :22)" ]; then
        /etc/init.d/dropbear restart 2>/dev/null
        /etc/init.d/dropbear enable
    fi
}

install() {
    # unlock SSH.
    unlock

    # host key is empty, restart dropbear to generate the host key.
    [ -s $host_key ] || /etc/init.d/dropbear restart 2>/dev/null

    # Backup the host key.
    if [ ! -s $host_key_bk ]; then
        i=0
        while [ $i -le 30 ]
        do
            if [ -s $host_key ]; then
                cp -f $host_key $host_key_bk 2>/dev/null
                break
            fi
            let i++
            sleep 1s
        done
    fi

    # Add script to system autostart
    uci set firewall.auto_ssh=include
    uci set firewall.auto_ssh.type='script'
    uci set firewall.auto_ssh.path="${auto_ssh_dir}/auto_ssh.sh"
    uci set firewall.auto_ssh.enabled='1'
    uci commit firewall
    echo -e "\033[32m SSH unlock complete. \033[0m"
}

uninstall() {
    # Remove scripts from system autostart
    uci delete firewall.auto_ssh
    uci commit firewall
    echo -e "\033[33m SSH unlock has been removed. \033[0m"
}

main() {
    [ -z "$1" ] && unlock && return
    case "$1" in
    install)
        install
        ;;
    uninstall)
        uninstall
        ;;
    *)
        echo -e "\033[31m Unknown parameter: $1 \033[0m"
        return 1
        ;;
    esac
}

main "$@"

执行以下代码

bash
cd  /data/auto_ssh
chmod +x auto_ssh.sh

uci set firewall.auto_ssh=include
uci set firewall.auto_ssh.type='script'
uci set firewall.auto_ssh.path='/data/auto_ssh/auto_ssh.sh'
uci set firewall.auto_ssh.enabled='1'
uci commit firewall
