在Cygwin中使用sshpass，ssh仍然提示输入密码

根据这个RedHat SSH 密码自动化指南我正在关注示例 4：GPG一，按照该指南中的步骤，我pass_file使用自己的密码创建我的密码。然后，我得到了这个：

gpg -d -q myappserver23.sshpasswd.gpg > pass_file && sshpass -fpass_file ssh [email protected]

-f请注意选项和pass_file根据之间缺少空格sshpass 手册页 当我运行上面的命令时，系统会要求我输入密码，我正确地输入它，然后系统会要求我输入服务器的密码，就好像sshpass根本没有使用过一样。简而言之，这有效但我仍然收到密码提示...

我当然知道这些-q选项，并且我也添加了-vvv这两个选项sshpass和SSH这似乎与嘘并且不sshpass我相信。我将在这里分享 ssh 横幅消息后收到的调试消息

此输出的最后一行是密码提示。显然，如果我在这里输入密码，我将能够登录远程服务器，但是使用它有什么意义呢sshpass？我希望能够无需输入任何密码即可登录。

请不要建议使用私钥，我了解这个主题，但它不适用于我的现实世界场景。任何帮助将不胜感激。

答案1

@KamilMaciorowski 评论让我找到了正确的方向。根据 ServerFault 上的这个有用的答案,视窗正在采取自己的开放SSH执行。要解决这个问题，openssh必须安装西格文为了使用这个来代替。

这解决了错误，现在我可以这样做：

$ gpg -d -q myappserver23.sshpasswd.gpg > pass_file && sshpass -fpass_file ssh [email protected] > test.txt

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

PD。这并不是不安全，因为我们gpg在这里使用。但如果有疑问，尝试这个。

答案2

为什么要解密为留在文件系统中的纯文本文件？最好管道直接输出：

gpg -d -q myappserver23.sshpasswd.gpg | sshpass -P pass ssh -i ~/.ssh/key.pem -ttR xxx.xxx.xxx.xxx

该-P pass选项搜索例如“密码...”或“密码短语”提示以填充。
