未能完全启动守护进程:连接超时

Question

在几次Ubuntu更新之后，这种情况开始发生。无论是通过使用LDAP客户端还是通过本地用户登录到此服务器，都需要很长时间才能进行身份验证和登录。

/var/log/auth.log：

服务器正在使用Ubuntu 16.04 LTS，并且：

Linux norwich 4.4.0-109-generic #132-Ubuntu SMP Tue Jan 9 19:52:39 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

我已经重新启动了服务器，没有任何效果。

这是日志日志：

Answer 1

这可能与以下方面有关：

• /var/run和/run没有符号链接。
• 您有一个有缺陷的dbus版本，请参阅https://bugs.freedesktop.org/show_bug.cgi?id=95263 --这似乎在dbus 1.11.10和一些补丁版本的1.10.x中得到了修正(在我看来，dbus 1.10.24-12.el7_6已经停止了，但也可能是巧合)。
