ssh - 为什么不尝试我的私钥？

Question

我正在尝试使用位于 的私钥连接到远程 SSH 服务器~/.ssh/id_rsa。当我ssh -v到服务器时，我得到以下信息：

...
debug1: Authentications that can continue: publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/martin/.ssh/id_rsa
debug1: Authentications that can continue: publickey
debug1: Offering RSA public key: martin@martin
debug1: Authentications that can continue: publickey
debug1: Trying private key: /home/martin/.ssh/id_dsa
debug1: Trying private key: /home/martin/.ssh/id_ecdsa
debug1: Trying private key: /home/martin/.ssh/id_ed25519
debug1: No more authentication methods to try.
Permission denied (publickey).

查看输出，似乎它甚至没有尝试我的私钥。我试过编辑 ~/.ssh/config，使用该-i选项，通过添加密钥ssh-add，但没有任何效果。

我确信公钥已正确安装在远程服务器上。任何人都可以帮助我吗？

martin@martin:~/.ssh$ ls -la

Answer 1

您的 ssh 客户端肯定会向远程 ssh 提供您的 RSA 密钥：

debug1: Offering RSA public key: /home/martin/.ssh/id_rsa
debug1: Authentications that can continue: publickey

但由于某种原因，远程服务器拒绝了它。无论您怎么想，都可以通过查看日志来确定原因。
