無法連接到 Centos 7 伺服器 (PAM)

在嘗試安裝 PAM 模組（我的第一個）後，我一直遇到這個問題。我最終將其刪除，因為該模組已損壞，導致使用者無法訪問系統。現在的情況是我也無法訪問它，即使在刪除它之後也是如此。

如何使用 PAM 解決此故障？

每個未找到的文件名#015的末尾都有一個。這不正常。由於八進制數015是用於輸入 (CR) 的 ASCII 碼，因此在我看來，您可能會/etc/pam.d在其中編輯某些文件，使其變為 DOS/Windows 模式（行尾的 CRLF 而不是 Linux/Unix LF-only行結束）。

您需要啟動到救援模式並從備份中恢復損壞的文件。您也可以使用命令擺脫\015字元。tr
