![远程用户帐户](https://linux22.com/image/159584/%E8%BF%9C%E7%A8%8B%E7%94%A8%E6%88%B7%E5%B8%90%E6%88%B7.png)
我最近将工作站从 Debian 9 升级到 Debian 10。使用旧版本,人们可以安装 USB 驱动器并播放和录制声音(用于视频会议)。更新后这两个都不起作用。
远程用户帐户
用户帐户存在一些特殊性,因此这可能是问题的根源。我们使用 NIS 和 NFS 在所有计算机上提供用户帐户和主目录。升级到 Debian 10 后,我需要添加一个NIS
to,/etc/nsswitch.conf
因为它们compat
之前是打开的,现在只有files
.也ypbind
没有运行,因为它不再用作
-broadcast
默认启动选项。我在以下位置添加了一个新的 systemd 文件
/etc/systemd/system/ypbind.service
:
[Unit]
Description=ypbind
Wants=network-online.target nis.service
After=network-online.target nis.service
[Service]
Type=simple
ExecStart=/usr/sbin/ypbind -broadcast -foreground
[Install]
WantedBy=multi-user.target
这样,用户帐户和主目录就在那里。在命令行上我也可以登录。但是 LightDM 显示管理器仍然不允许用户登录。所以在/etc/lightdm/lightdm.conf
本节中[LightDM]
我添加了该选项greeter-show-manual-login = True
,从那时起远程用户就可以登录了。有些机器仍然将 GDM 作为默认设置显示管理器,登录显示的行为与我更改配置之前 LightDM 的行为相同。密码检查通过,屏幕可能会短暂变黑,然后再次显示登录屏幕。当用户超出配额并且.Xauthority
无法创建建立会话 (?) 所需的文件时,也会发生同样的情况。
奇怪的是,当我通过 SSH 登录并在实际屏幕上登录时,这些会话会正确显示who
:
$ who
ueding pts/0 2019-08-26 12:42 (131.220.226.20)
ueding tty7 2019-08-26 12:43 (:0)
但同时该会话未列出loginctl
:
$ loginctl
No sessions.
当我使用本地用户帐户在我的个人 Fedora 30 笔记本电脑上执行相同操作时,我会得到以下输出who
:
$ who
mu tty1 2019-08-25 10:33 (:0)
mu pts/0 2019-08-25 10:34 (:0)
mu pts/1 2019-08-26 12:08 (:0)
mu pts/2 2019-08-26 12:14 (:0)
mu pts/3 2019-08-26 12:42 (:0)
mu pts/4 2019-08-26 12:38 (:0)
mu pts/5 2019-08-26 12:55 (:0)
并且还loginctl
显示了一些明智的内容:
$ loginctl
SESSION UID USER SEAT TTY
1 1000 mu seat0
1 sessions listed.
我创建了一个新的当地的在 Debian 10 工作站之一上使用 UID 50000 的用户帐户,发现我可以登录,会话显示出来loginctl
,而且下面描述的可移动媒体和声音问题也不存在,声音和可移动媒体正常。所以这确实是来自 NIS 的用户的问题。
到目前为止,让我印象深刻的一件事是,由于历史原因,我们给出的用户 id 以 500 开头。但我的用户的ueding
uid 为 1085,所以即使这是帐户未列出的问题,这account 应该没问题,因为不被视为系统用户的用户 ID 的默认起始值为 1000。
我没有足够的经验,但我有感觉不知何故,用户帐户并不完全在系统中,只是还缺少一些东西。
一名 uid 为 536 的用户在登录后必须输入他的 GNOME 钥匙串密码。我不确定他是否有不同的密码,但也可能是在启动过程中未解锁。不过,这可能没有任何意义。
验证日志
/var/log/auth.log
在当前状态下,这是自启动计算机、通过 SSH 以 root 身份连接以检索日志并使用我的 NIS 用户登录计算机本身以来显示的所有内容。用户还monitoring
通过 SSH 登录来检索我的监控系统的一些信息。

目前的结论
我觉得有一些东西阻止用户“完全登录”,从某种意义上说,他们确实有一个 Xfce 会话并且可以看到他们的主目录,但不足以注册诸如
logind
Pulse Audio 之类的“花哨”东西。或者也许他们缺少一个特殊的用户群体。计算机上的本地用户帐户按预期工作,因此这肯定是一般用户帐户的问题,而不是症状之一(loginctl
输出、声音、可移动媒体)。
我无法真正理解这一点,我不确定我到底应该看哪里。非常欢迎指针或(希望)解决方案!
答案1
我遇到了同样的问题,最终发现了这个: https://github.com/systemd/systemd/issues/7074
我尝试了各种技巧,但最终为我解决的方法很简单:
sudo apt-get install nscd
这是“apt-cache show nscd”的内容:
