win端连接linux端共享

powershell上对SMB1协议进行操作

Get-SmbServerConfiguration | Select EnableSMB1Protocol, EnableSMB2Protocol                   #查看协议配置的当前状态
Set-SmbServerConfiguration -EnableSMB1Protocol $false       #禁用 SMBv1
Set-SmbServerConfiguration -EnableSMB1Protocol $true        #启用 SMBv1

windows上启SMB 1.0/CIFS文件共享支特，安装重启，后

可以看到成功登录上tom1的smb服务器

tom_test为tang组共享目录，且tang为tom1的属组。tom1目录为tom1用户的主目录，可在配置文件中配置开放或关闭。
