git - OpenSSH 提供了错误的公钥？

Question

我尝试将 ssh 配置为使用两个 Remote ，每个 Remote 都有不同的 key 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).

这是 Cloudhost 的调试输出。

> ssh -v git.cloudhost.io

行 Offering public key: /c/Users/Name/.ssh/cloudhost让我很困惑，因为 cloudhost是私钥。公钥名为 cloudhost.pub .

如何以我的登录用户身份通过​​ ssh 连接到 Cloudhost？

Answer 1

从您的日志中:

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？请仔细检查这两个文件的内容。

也看看这个:

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 key ，它存在并且甚至被服务器接受。

你确定那个文件不存在吗？您确定您正在与正确的服务器通话吗？您确定您在服务器上正确配置了您的公钥吗？
