服务器：Debian 8，客户端：一些 Windows 和一些 Xubuntu 16.04
由于我将一个 Xubuntu 客户端更新到 4.13.0-26，我无法挂载 samba 共享。
[20390.135208] No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1) specify vers=1.0 on mount.
[20390.161744] CIFS VFS: protocol revalidation - security settings mismatch

我知道这与 smb-Protokoll 有关，但是当我使用
testparm -v | grep protocol
在我的服务器上它说：

据我了解，服务器是否支持 SMB2 和 SMB3。我尝试了这个添加
[home]
min protocol = SMB2
分别
[home]
min protocol = SMB3
比我在服务器中看到的：
server max protocol = SMB3
server min protocol = SMB3
分别
server max protocol = SMB3
server min protocol = SMB2
但客户端还是无法挂载。
这是客户端 fstab 的一部分：
//192.168.0.251/firmendaten /home/username/server/firmendaten cifs gid=1000,uid=1000,file_mode=0660,dir_mode=0770,user,noauto,credentials=/home/username/.smbcredentials
如何使用安全协议 SMB2 / SMB3 进行安装？
提前致谢！
答案1
我找到了解决方案。它适用于在客户端安装时添加版本
//192.168.0.251/firmendaten /home/username/server/firmendaten cifs gid=1000,uid=1000,file_mode=0660,dir_mode=0770,user,noauto,vers=2.1,credentials=/home/username/.smbcredentials
我以为我可以在服务器的 smb.conf 上做一些事情，但这也有效。
