OpenSSH提供错误的公钥？

Question

我尝试将ssh配置为使用两个遥控器，每个遥控器是一个不同的密钥对。因此，我创建了这个config。

UserKnownHostsFile ~/.ssh/known_hosts

Host github.com
    User git
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/github_rsa

Host git.cloudhost.io
    User git
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/cloudhost

与Github的连接工作正常。

> ssh -T github.com
Hi danijar! You've successfully authenticated, but GitHub does not provide shell
access.

但是对于Cloudhost，连接失败。

> ssh -T git.cloudhost.io
Permission denied (publickey,password).

以下是Cloudhost的调试输出。

> ssh -v git.cloudhost.io

Offering public key: /c/Users/Name/.ssh/cloudhost行使我感到困惑，因为cloudhost是私钥。公钥名为cloudhost.pub。

如何通过ssh作为登录用户连接到Cloudhost？

Answer 1

从你的日志中：

debug1: Reading configuration data /c/Users/Name/.ssh/config
debug1: Applying options for git.cloudhost.io
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *

这是正确的配置文件吗？请仔细检查两个文件的内容。

还请看以下内容：

debug1: Offering public key: C:\\Users\\Name\\.ssh\\github_rsa
debug1: Server accepts key: pkalg ssh-rsa blen 277
debug1: Authentication succeeded (publickey).

似乎它提供了您的github密钥，它已经存在，甚至被服务器所接受。

您确定该文件不存在吗？你确定你在和正确的服务器通话吗？确定在服务器上正确配置了公钥吗？
