Cygwin中使用sshpass，ssh仍然提示輸入密碼

根據此RedHat SSH 密碼自動化指南，我將遵循範例 4：GPG一，並按照該指南中的步驟pass_file使用自己的密碼創建我的密碼。然後，我得到了這個：

gpg -d -q myappserver23.sshpasswd.gpg > pass_file && sshpass -fpass_file ssh myuser@xxx.xxx.xxx.xxx

注意-f選項之間沒有空格，pass_file根據sshpass 手冊頁 當我執行上面的命令時，我被要求輸入密碼，我輸入正確，然後我被要求輸入伺服器的密碼，就好像sshpass沒有用過的。簡而言之，這可行，但我仍然收到密碼提示…

我-q當然知道這些選項，並且我還添加-vvv了sshpass和ssh，我相信這似乎與shh而不是sshpass有關。我將在這里分享我在 ssh 橫幅消息之後收到的調試消息

此輸出的最後一行是密碼提示。顯然，如果我在這裡輸入我的密碼，我將能夠登錄到遠端伺服器，但是，使用有什麼意義sshpass呢？我希望能夠無需輸入任何密碼即可登錄。

請不要建議使用私鑰，我知道這個主題，但它不適用於我的現實世界場景。任何幫助將不勝感激。

@KamilMaciorowski 評論讓我朝著正確的方向前進。根據 ServerFault 這個有用的答案，Windows正在採用自己的OpenSSH實現。為了解決這個問題，openssh必須在Cygwin中安裝才能使用這個。

這解決了錯誤，現在我可以這樣做：

$ gpg -d -q myappserver23.sshpasswd.gpg > pass_file && sshpass -fpass_file ssh myuser@xxx.xxx.xxx.xxx > test.txt

$ cat test.txt
/home/myuser
uid=1001(myuser) gid=1001(mygroup) groups=1001(mygroup)

PD。這不是不安全的，因為我們在gpg這裡使用。但如果有疑問，試試這個。
