Ubuntu 20.04“沒有為使用者設定 LanMan 密碼”

我的設定：帶有 Ubuntu 20.04 的伺服器和 samba 共用。 HP Deskjet 8620 Pro 印表機。

印表機提供稱為「掃描到網路資料夾」的功能。它曾經可以在 Ubuntu 16.04 上運行，但自從更新後就不行了。谷歌搜尋我發現這台印表機使用的是非常舊的 smb 協定版本。

我發現這建議設定的帖子

[global]
   ntlm auth = yes
   lanman auth = yes

在 smb.conf 中。

新增這兩行後，我重新啟動了 samba 並更改了對應 smb 使用者的密碼：

sudo systemctl restart smbd.server nmbd.service
sudo smbpasswd hpscanner

Samba 調試日誌仍然告訴我「沒有為用戶 hpscanner 設定 LanMan 密碼」：

那麼如何正確設定LanMan密碼呢？

我可以將 samba 設定為僅針對該使用者排除此舊身份驗證嗎？

謝謝！

編輯：

我添加了

server min protocol = NT1

正如答案中所建議的。這並沒有改變任何事情。

有任何想法嗎？

答案1

我想你已經快到了。

您的 HP 印表機正在嘗試使用 smb 的 SMB1（Samba 稱之為 NT1）方言連接到 Ubuntu 伺服器。在 Ubuntu 16 或 18 中這不是問題。在 Ubuntu 20 中，Samba 預設為關閉它。

您可以透過編輯 smb.conf 在 Ubuntu 20 中啟用它，並在 workgroup = WORKGROUP 行下新增以下一項：

server min protocol = NT1

您可以嘗試重新啟動 smbd sudo service smbd restart，但可能必須重新啟動。

答案2

最後解決了：

[global]
   server min protocol = NT1
   ntlm auth = yes
   lanman auth = yes

並設定一個新的密碼由

sudo smbpasswd username

按照 Morbius1 的建議解決了它。

但我還有兩件事要考慮：

  1. 設定與之前相同的密碼不會重置雜湊值。
  2. 密碼最大長度為 14 個字元。對於較長的密碼，將不會設定雜湊值。

可以使用以下命令檢查哈希值

pdbedit -L -w

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 代表未設定。
