一、刷armbian

N1已降级，“N1-ADBU盘启动（傻瓜包）”开启U盘启动。

1. 文章推荐armbian 5.77比较稳定。
   https://www.right.com.cn/forum/thread-498873-1-1.html

2. U盘刷入armbian，下载dtb文件放到U盘dtb文件夹。
   meson-gxl-s905d-phicomm-n1-xiangsm.dtb

3. 打开uEnv.ini,修改配置
   

4. U盘插入靠近HDMI接口的USB，N1插电启动，找到N1的IP地址，putty连接
   初始用户名,密码为root，1234

5. 写入EMMC，完成后关机，拔U盘重启
   /root/install.sh

二、更改软件源

1. 源文件 /etc/apt/sources.list
   中科大源
   deb http://mirrors.ustc.edu.cn/debian stretch main contrib non-free
deb http://mirrors.ustc.edu.cn/debian stretch-updates main contrib non-free

2. 更新
   sudo apt update
sudo apt upgrade

三、安装SMB

进入armbian-config，到安装软件页面，Samba空格选中，再回车安装。

四、配置SMB

1. 修改配置文件/etc/samba/smb.conf，直接覆盖原内容，实现匿名直接连接。

[global]
	workgroup = WORKGROUP
    server string = Samba Server Version %v
    passdb backend = tdbsam
    cups options = raw
    security = user                    #认证模式为User
    map to guest = bad user            #这个很关键，实现匿名无须交互输入用户名和密码就靠它了
    guest account = guest              #匿名用户映射为guest用户

[myshare]                    #共享后看到的文件夹名
    comment = My share
    path = /home/public      #共享路径
    browseable = Yes         #可以被浏览，就是在网络邻居中能看到共享名
    read only = No           #可读写
    guest ok = Yes           #允许匿名访问，这个也需要设置，否则匿名无法访问
    valid users = samba liuag guest    #有效的用户和组
    invalid users = liuben   #无效用户和组   
    read list = samba    #只读用户和组(如果read only = No，只读用户需要在此设置)
    write list = liuag   #可读写用户和组(如果read only = Yes，可读写用户需要在此设置)
    allow hosts = 192.168.100.236    #允许访问主机列表，支持通配符
    deny hosts = 192.168.100.0/24    #禁止访问主机列表，支持通配符

简洁版

[global]
       workgroup = WORKGROUP
       security = user
       map to guest = Bad User
[media]
       comment = resources
       path = /home/public
       public = yes
       writable = yes
       guest ok = yes
       browseable = yes

2. 修改目录权限
   chmod -R 777 /home/public
3. 开机启动SMB
   systemctl enable samba
4. 重启SMB
   systemctl restart samba

五、挂载U盘

1. 插上U盘，lsblk查看U盘盘符，这里是/dev/sda1
   

2. 挂载U盘到刚才的共享目录/home/public
mount /dev/sda1 /home/public

3. 用命令blkid /dev/sda1查看UUID并记下

4. 设置开机挂载，nano /etc/fstab，加上以下内容，ntfs为当前U盘类型
   UUID=722059EC2059B835 /home/public ntfs defaults 0 0

5. 启动挂载（好像不用这步也可以）
   mount -a

六、固定MAC，更新时间

1. ifconfig记录当前MAC地址
2. 修改配置文件nano /etc/network/interfaces

source /etc/network/interfaces.d/*

# Wired adapter #1
#allow-hotplug eth0
auto eth0
no-auto-down eth0
iface eth0 inet dhcp
hwaddress fc:7b:07:87:44:33  #新增此条
#address 192.168.0.100
#netmask 255.255.255.0

3. 改为上海时区
   cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
4. ntp设置

apt -y install ntp
apt -y install ntpdate
ntpdate -u ntp.aliyun.com #阿里云 ntp 服务器
