Answer 1

我怀疑你的私钥出了什么问题，可能是第一行。

不要把它粘贴到问题中。

你是怎么生成私钥的？你能试着创造一个新的吗？(请记住，它们是成对的，所以只有在您也可以在另一端更改公钥的情况下才会这样做。)

Answer 2

密钥很可能是SSL或PuTTY格式的。它与Linux客户机/服务器不兼容。

Answer 3

是的，这是格式-看上去像一个肉酱生成的钥匙。

若要正确剪切/粘贴puttygen键，请参见此处：http://www.howtoforge.com/how-to-configure-ssh-keys-authentication-with-putty-and-linux-server-in-5-quick-steps

但是--你不是从Windows电脑上跳出来的，是吗？看起来你从一个基于Debian的服务器变成了一个私有IP。你想在另一个主机上使用puttygen键吗？为什么这样做而不是'ssh-keygen'？

我很好奇你在这里想做什么。你能给出更多细节吗？
