Gerrit SSH权限被拒绝（公钥）

Question

我在使用ssh时无法通过gerrit.openbmc-project.xyz进行身份验证。

我正在尝试在windows上使用ssh。

我的.ssh\config文件如下：

Host openbmc.gerrit
        Hostname gerrit.openbmc-project.xyz
        Port 29418
        User patelutpal

我的 *.ssh* 目录的内容如下：

-rw-r--r-- 1 utpalp 1049089  107 Dec  7 23:04 config
-rw-r--r-- 1 utpalp 1049089  411 Dec  7 21:10 id_ed25519
-rw-r--r-- 1 utpalp 1049089   97 Dec  7 21:10 id_ed25519.pub
-rw-r--r-- 1 utpalp 1049089 3381 Dec  7 22:14 id_rsa
-rw-r--r-- 1 utpalp 1049089  741 Dec  7 22:14 id_rsa.pub
-rw-r--r-- 1 utpalp 1049089  419 Dec  7 22:53 known_hosts

我使用我的 Github 账户，ID 为 patelutpal，登录了 gerrit.openbmc-project.xyz。

我在 https://gerrit.openbmc-project.xyz/settings/#SSHKeys 中添加了 id_rsa.pub SSH 密钥设置。

当我尝试：

C:\Users\utpalp\git>ssh -p 29418 -vvvt [e-mail]

我得到以下输出。

我不知道该怎么办。我认为我已经做了所有正确的事情。我想知道这是否是服务器端错误。请有人帮忙吗？

如果需要，我将乐意提供更多信息。

Answer 1

背景

OpenSSH 8.8 禁用了使用 SHA-1 哈希算法的 RSA 签名，因为它们被认为是 密码学上已被攻破的。 Git for Windows 2.33.1 将 OpenSSH 升级到 8.8。

请注意，这只是客户端限制。

错误

尝试使用更新的 SSH 客户端与 git 使用 SSH 克隆或提取时，可能会出现以下错误：

git fetch
Fetching origin
[e-mail]: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
error: Could not fetch origin
Done

解决方案

您需要提供一种OpenSSH 8.8接受的密钥类型。OpenSSH 建议使用Ed25519等：

ssh-keygen -t ed25519 -C "[e-mail]"

把“.ssh/id_ed25519.pub”文件的内容复制到您的Gerrit用户设置中。

如果您的“$HOME/.ssh/config”文件设置了IdentityFile选项，则可能需要相应更改路径，例如：

Host your.gerrit.host
IdentityFile ~/.ssh/id_ed25519

另外，您可以通过在~/.ssh/config中添加以下ssh配置选项来配置客户端接受RSA：

PubkeyAcceptedKeyTypes +ssh-rsa

非常感谢！我整天都在解决这个问题，但一直找不出我做错了什么。供参考：我的WSL实例有一个旧的SSH/OpenSSL。所以我下载了它们并从源代码构建。安装完后，我还是一直收到gerrit拒绝我的公钥的消息。我以为我可能链接或安装ssh的方式不对，导致它没有使用~/.ssh/id_rsa密钥。但是使用ed25519密钥生成器后，将其添加到gerrit后，一切立刻就正常了。再次强调：我使用的是WSL Ubuntu，而不是直接在Windows上操作，以供以后参考。 - undefined

Answer 2

我最近在Windows和GitBash上遇到了类似的问题。我降级到了GitBash 2.27，然后问题得到了解决。

我不认为建议一个人降级一个程序或库是正确的建议。如果有什么变化，那么我们必须知道为什么以及新的操作方法是什么（就像其他答案所解释的那样）。 - undefined
