当写到单独共享时之对此共享生效，当写到【GLOBAL】时对samba整体生效，下面是写到单独的共享目录westos_smb中的
hosts allow 172.25.254.30 白名单
hosts deny 172.25.254.50 黑名单
samba 的常用配置参数 #####
writable = yes ##可写
write list = westos ##指定用户可写
write list = +westos ##指定组成员可写
write list = @westos ##指定组成员可写
valid users = lee ##指定访问用户，只有lee可以使用共享文件
valid users = +lee|@lee ##指定访问组
browseable = yes|no ##是否隐藏共享，隐藏后看不见共享文件，但可以使用
map to guest = bad user ##写到全局设定中
guest ok = yes ##允许匿名用户访问
admin users = lee ##指定此共享的超级用户身份
