如何使用新的 smbclient 連接到舊的 Samba 伺服器？

我執行的基於 Linux 的多媒體盒smbd，它的版本報告為3.0.30。

smbclient4.10 曾經能夠連接到它，但是，在將客戶端升級到4.13.8後，我NT_STATUS_CONNECTION_DISCONNECTED會在啟動時立即…

我敢肯定，這是由於在最新版本的 Samba 中禁用了某些選項——但是哪一個？我可以通過編輯重新啟用它smb.conf（如何？），還是完全刪除它並且我需要降級客戶端（到 4.12？）？

在調試級別 9，這是我得到的：

降級回 4.10 後，上述詳細日誌記錄以正確的密碼提示結束：

“ NT1 方言”是否已從 Samba-4.12 和 4.13 中刪除？我可以通過配置文件重新啟用它嗎？

將以下行添加到 .[global]部分後smb.conf，我能夠讓 Samba-4.13 連接到此設備：

client min protocol = NT1
