我有一台 2013 MacBook Pro，它已经在 MacOS 10.15.7 (19H2026) 上运行了很长一段时间。它配置为接受无密码 SSH 连接。几天前，当我尝试 SSH 登录时，它突然开始提示输入密码。我正在使用运行 macOS Sonoma 14.2.1 的 MacBook Air (M1, 2020) 连接到 2013 MacBook Pro。
我已经验证过的事情：
~/.ssh（700）、~/.ssh/id_rsa.pub（644）~/.ssh/id_rsa和~/.ssh/authorized_keys（600）的权限- 唯一未注释的行
/etc/ssh/sshd_config是：AuthorizedKeysFile .ssh/authorized_keys UsePAM yes AcceptEnv LANG LC_* Subsystem sftp /usr/libexec/sftp-server XAuthLocation /opt/X11/bin/xauth - 远程登录已启用。GUI 已停止工作，因此我必须使用这个命令行解决方案，但我还是可以通过提供密码登录。
- 我已重新启动 Catalina 盒子。
- 我的客户端是最新的 MacBook Air，它仍然可以通过 SSH 连接到 Catalina 机器上的 VM 中运行的最新 Linux。
- “什么都没变！我发誓！”
假设这些sshd_config参数是正确的（文件的修改日期是 2023 年 6 月，我不知道这是我的问题还是系统更新的问题），还有哪些其他方法可以尝试？

以下是 的输出ssh -vvv <macbook-pro>：

答案1
/Users/chap/我注意到MacBook Pro（10.15.7）的权限为777。将其更改为 755 即可解决所有问题。
我不确定权限何时或如何更改，或者还有什么可能更改，以至于这些不正确的权限现在导致公钥 SSH 身份验证失败。系统信息软件安装日志列出的更新版本没有比 MacOS Catalina 安全更新 2022-005（于 2022 年 8 月 27 日应用）更新的版本。我每天都登录这台机器，登录失败只是几天前才开始的。
更新： 某物做过改变：
我在运行 Homebrew 的 Catalina 机器上有一个特殊的专用用户。但是，我遇到问题的用户并不是这个。我认为，就像在较新版本的 macOS 中一样，我可以通过将其安装目录添加到$PATH中的变量来启用 Homebrew 的存在.bash_profile。在 Sonoma 上，它是/opt/homebrew。在 Catalina 及更早版本上，它是/usr/local/bin。
对于我通过 SSH 连接时遇到问题的用户，我省略了附加内容/usr/local/bin，$PATH目的是从混合中消除任何与 Homebrew 相关的安装。
我错了。
事实证明系统— 即 macOS — 自动添加/usr/local/bin到$PATH前面。
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin
此外，当我最近运行时brew upgrade，它升级了openssl：
$ /usr/bin/openssl version
LibreSSL 2.8.3
$ /usr/local/bin/openssl version
OpenSSL 3.2.1 30 Jan 2024 (Library: OpenSSL 3.2.1 30 Jan 2024)
所以一直以来，每一个我的 Catalina 上的 SSH 用户一直在访问 Homebrew 提供的 OpenSSL，和它最近进行了更新。我不知道这究竟是如何改变 SSH 的工作方式的，但似乎最近的 Homebrew 升级在某种程度上导致了这个问题。

答案2
正如解释的那样OSXDaily 上的这篇文章：
“此问题的明显原因是 MacOS Ventura 附带的 OpenSSH 版本默认禁用 RSA 签名，因此您可以通过使用更安全的哈希或简单地允许 RSA 签名来解决问题。”
因此，要解决此问题，请在 MacBook Air 上编辑/创建此文件；权限644（又名-rw-r--r--：）：
~/.ssh/config
现在添加以下内容：
Host *
HostkeyAlgorithms +ssh-rsa
PubkeyAcceptedAlgorithms +ssh-rsa
保存它并再次尝试通过 SSH 连接到 MacBook Pro。它应该可以工作。如果不行，请编辑您的问题以添加 SSH 的详细输出，如下所示：
ssh -vvv [hostname]
当然，[hostname]与您的 MacBook Pro 的 IP 地址或主机名交换。
更新：如果我建议的原始方法~/.ssh/config不起作用，请尝试使用第三个设置PubkeyAcceptedKeyTypes：
Host *
HostkeyAlgorithms +ssh-rsa
PubkeyAcceptedAlgorithms +ssh-rsa
PubkeyAcceptedKeyTypes +ssh-rsa
