Ubuntu 20.04“未为用户设置 LanMan 密码”

我的设置：带有 samba 共享的 Ubuntu 20.04 服务器。HP Deskjet 8620 Pro 打印机。

打印机提供了一项名为“扫描到网络文件夹”的功能。它以前可以与 Ubuntu 16.04 配合使用，但自从更新后就无法使用了。通过谷歌搜索，我发现这台打印机使用的是非常旧的 smb 协议版本。

我发现这建议设置的帖子

[global]
   ntlm auth = yes
   lanman auth = yes

在 smb.conf 中。

添加这两行后，我重新启动了 samba 并更改了相应 smb 用户的密码：

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

Samba 调试日志仍然告诉我“没有为用户 hpscanner 设置 LanMan 密码”：

那么如何正确设置LanMan密码呢？

我可以将 Samba 配置为仅为这一个用户接受这个旧的身份验证吗？

谢谢！

编辑：

我添加了

server min protocol = NT1

正如答案中所建议的那样。这并没有改变任何事情。

有任何想法吗？

答案1

我想你已经快到了。

您的 HP 打印机正在尝试使用 smb 的 SMB1（Samba 称之为 NT1）方言连接到 Ubuntu 服务器。在 Ubuntu 16 或 18 中这不是问题。在 Ubuntu 20 中，Samba 默认将其关闭。

您可以在 Ubuntu 20 中通过编辑 smb.conf 来启用它，并在 workgroup = WORKGROUP 行下添加以下内容：

server min protocol = NT1

您可以尝试重新启动 smbd sudo service smbd restart，但可能只需要重新启动即可。

答案2

终于解决了：

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

并设置新的密码

sudo smbpasswd username

按照 Morbius1 的建议解决了这个问题。

但我还需要考虑两件事：

  1. 设置与之前相同的密码不会重置哈希。
  2. 密码的最大长度为 14 个字符。如果密码过长，则不会设置哈希值。

可以使用以下方法检查哈希值

pdbedit -L -w

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX代表未设置。
