如何使用新的 smbclient 连接到旧的 Samba 服务器？

我运行了一个基于 Linux 的多媒体盒smbd，其版本报告为3.0.30。

smbclient4.10以前可以连接，但是，升级客户端后4.13.8，我NT_STATUS_CONNECTION_DISCONNECTED一启动就立即...

我确信，这是由于最新版本的 Samba 中某些选项被禁用所致——但是是哪一个呢？我可以通过编辑重新启用它smb.conf（如何？），还是完全删除它并且我需要将客户端降级（到 4.12？）？

在调试级别 9 下，我得到的结果如下：

降级回 4.10 后，上述详细日志记录以正确的密码提示结束：

有 ”NT1方言“已从 Samba-4.12 和 4.13 中删除？我可以通过配置文件重新启用它吗？

答案1

将以下行添加到[global]的部分后smb.conf，我能够让 Samba-4.13 连接到该设备：

smb配置文件

[global]
client min protocol = NT1
