Sftp
CYGWIN SFTP 突然不工作了。認證後連接關閉
幾週前，我在一些 Win 2003 R2 x64 伺服器上安裝了用於 SFTP 的 CYGWIN，最初它們都可以正常工作。然而，本週問題出現了，使用者無法通過 SFTP 連接到 2 台伺服器。連接時，認證後立即提示錯誤“連接已關閉”。對於第一台伺服器，我們重新安裝並重新配置了 CYGWIN，它又開始工作了。但是今天另一台伺服器再次遇到同樣的錯誤，所以我想找出問題所在，以防止其他伺服器遇到同樣的問題。我做了一個 SFTP -v 並且輸出如下：

Google搜尋並看到一些提到的 /etc/passwd 問題，但我再次嘗試 mkpasswd 並且它不起作用。
任何幫助將不勝感激。

這是 syslog-ng，但似乎無法在此處找到有用的資訊。

謝謝你。
再次編輯，添加 DEBUG3 日誌級別。
