与 mac 配对错误无法执行 'grep "ssh-rsa ...."

Ste*_*eve 3 xamarin.ios xamarin

我尝试将我的 Macbook 与 Visual Studio 2022 配对，但输入凭据后，我在 gui 对话框中收到以下错误：“尝试使用 SSH 密钥与‘192.168.178.27:22’建立 SSH 连接时出错”

检查日志时出现以下错误：

关于丢失文件的例外情况具有误导性。首先它不存在，但如果您在连接过程中查看该文件夹，它会与其他文件一起创建，当失败时，它会再次被删除。所以我假设这是一个不同的错误。

并且 ssh 登录到机器，一切正常。我可以通过 ssh 进入它，如果您启用详细登录，则其他命令以及 scp 都可以正常执行。

有没有人遇到过这个问题并有解决方案？

事实证明，对于我遇到的类似问题，根本原因是由于Ventura而与SSH相关，与VS或防火墙无关。

这篇文章描述了问题和解决方案。

macOS Ventura 附带 OpenSSH_9.0p1，默认情况下禁用使用 SHA1 算法的 RSA 签名。如果您阅读发行说明，您可以找到重新启用它的方法，直到 Microsoft 发布 Xamarin 配对的 SSH 实现的更新。

可能不兼容的更改

此版本默认禁用使用 SHA-1 哈希算法的 RSA 签名。进行此更改是因为 SHA-1 哈希算法在密码学上已被破坏，并且可能会造成 <USD$50K 的选择前缀哈希冲突

对于大多数用户来说，此更改应该是不可见的，并且无需替换 ssh-rsa 密钥。OpenSSH 自 7.2 版起就支持 RFC8332 RSA/SHA-256/512 签名，现有的 ssh-rsa 密钥将在可能的情况下自动使用更强的算法。

这篇文章介绍了如何在不重新启动计算机的情况下重新启动 SSHD。

我按照这些步骤操作，不再遇到与 SSH 相关的连接/配对问题。
