前言

本文主要记录使用在使用Linux中一些不会的技巧做得笔记，不定时增加新的技巧。

Linux共享

如何共享给小米电视

本文小节出现的时间为2022-07-14，此时间内小米电视仍无法通过电脑直接共享的形式读取到文件

小米电视可以访问电脑共享文件，但是直接共享后是无法识别的，主要是小米工程师不知道在干啥，还在用古老的SMB 1.0的协议，SMB 1.0协议因为漏洞问题新的系统默认都是禁止的，所以只能开启SMB 1.0协议。

# 编辑samba的配置文件
sudo vim /etc/samba/smb.conf

# 打开文件后找到 [global] 后，添加以下内容
server min protocol = CORE

警告

如果设备在公网中就别开启了，老老实实用U盘吧。

时间模块
