samba config example

## Samba的基本概念

Samba服务：是提供基于Linux和Windows的共享文件服务，服务端和客户端都可以是Linux或Windows操作系统。可以基于特定的用户访问，功能比NFS更强大。

Samba与ftp和nfs的区别：

- ftp：基于Linux和Windows共享文件的服务，但是不安全，因为ftp可以匿名访问，匿名用户可以获取读写权限，所以不常用
- nfs：只能做Linux的共享文件服务，服务端和客户端都只能是Linux操作系统

samba的服务名、对应端口号及作用：

- smbd：139 提供文件的共享访问
- nmbd：445 提供基于域名的访问
