[AX3600] AX3600、AX1800、AX5官方固件开启SSH方法

进入路由复制串号，替换下面的小写stok等号右边的大写<STOK>，带符号一起替换，不要说误人子弟，细心的复制串号就可对比发现
开ssh命令：

http://192.168.31.1/cgi-bin/luci/;stok=<STOK>/api/misystem/set_config_iotdev?bssid=Xiaomi&user_id=longdike&ssid=-h%3B%20nvram%20set%20ssh_en%3D1%3B%20nvram%20commit%3B%20sed%20-i%20's%2Fchannel%3D.*%2Fchannel%3D%5C%22debug%5C%22%2Fg'%20%2Fetc%2Finit.d%2Fdropbear%3B%20%2Fetc%2Finit.d%2Fdropbear%20start%3B

改密码命令(必须改密码，不改密码无法连接ssh)：改密码为admin

http://192.168.31.1/cgi-bin/luci/;stok=<STOK>/api/misystem/set_config_iotdev?bssid=Xiaomi&user_id=longdike&ssid=-h%3B%20echo%20-e%20'admin%5Cnadmin'%20%7C%20passwd%20root%3B

改成一行

http://192.168.31.1/cgi-bin/luci/;stok=<STOK>/api/misystem/set_config_iotdev?bssid=Xiaomi&user_id=longdike&ssid=-h%3B%20nvram%20set%20ssh_en%3D1%3B%20nvram%20commit%3B%20sed%20-i%20's%2Fchannel%3D.*%2Fchannel%3D%5C%22debug%5C%22%2Fg'%20%2Fetc%2Finit.d%2Fdropbear%3B%20%2Fetc%2Finit.d%2Fdropbear%20start%3B%20echo%20-e%20'admin%5Cnadmin'%20%7C%20passwd%20root%3B

升级后防止ssh失效方法：

在 /etc/firewall.user 文件中，添加一句 source /etc/basic_settings/basefile.sh
虽然可以直接写脚本，但毕竟这里是写防火墙规则的地方，为了看起来美观，只source一个脚本，把主要命令写在别的地方。

1. echo -e "\nsource /etc/basic_settings/basefile.sh" >> /etc/firewall.user

创建 basic_settings 文件夹、basefile.sh 文件、my_script.sh 文件

1. mkdir /etc/basic_settings
2. touch /etc/basic_settings/basefile.sh
3. touch /etc/basic_settings/my_script.sh
4. chmod 755 /etc/basic_settings/basefile.sh
5. chmod 755 /etc/basic_settings/my_script.sh

编辑 /etc/basic_settings/basefile.sh 填写以下内容

1. echo "source /etc/basic_settings/my_script.sh; exit 0" > /etc/rc.local

编辑 /etc/basic_settings/my_script.sh 填写以下内容

1. ver_flag="$(uci -c /usr/share/xiaoqiang get xiaoqiang_version.version.CHANNEL)"
2. if [ "$(nvram get ssh_en)" != "1" -o "$ver_flag" == "release" ]; then
3. echo "$(date) : 本次开机ssh_en被关闭或者版本标记被重置，您可能进行了固件升级。" >> /tmp/my_log.txt
4. nvram set ssh_en=1
5. nvram commit
6. uci -c /usr/share/xiaoqiang set xiaoqiang_version.version.CHANNEL='stable'
7. uci -c /usr/share/xiaoqiang commit xiaoqiang_version.version
8. echo "$(date) :已重新开启ssh_en，并设置版本标记为stable。" >> /tmp/my_log.txt
9. /etc/init.d/dropbear enabled
10. if [ $? == "1" ]; then
11. echo "$(date) :dropbear开机自启动被关闭，现重新开启。" >> /tmp/my_log.txt
12. /etc/init.d/dropbear enable
13. fi
14. /etc/init.d/dropbear restart
15. echo -e "admin\nadmin" | passwd root
16. echo "$(date) :已将root密码重置为 admin" >> /tmp/my_log.txt
17. fi
