我无法通过 SSH 连接到我的 GCP 实例。从基于 Web 的控制台通过 SSH 连接没问题，我可以使用笔记本电脑上的 Google Cloud SDK shell 进行连接，这排除了连接或防火墙问题。
我已尝试启用操作系统登录：
我不太明白这一点，所以我尝试直接添加 SSH 密钥：
这是我的文件中的公钥部分id_rsa，从 puttygen 复制而来：
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD3u7O9pk3YtE10hjaRAWixkwAv6rvOIiMnF+KOQyO/MG8GcGKUypL3nNbotmvPu8hlROz/GghkkSxzp3Bubm+8K+K4A8s68tyUenYXZcdN71BOVnY1F23gt9FfwHO5n9M9nQQwwyHtVJtRF7RPPJpD8L3NO1M7YxKSoW10+omEOBhAjo5PS0pcaiaUoh5C9Z0+fpmZPuFEZ43w9MFxt5LPU/46LwoYCvNOGFICAHshpQRsl94v+QzHzAShCvwjPkCryMDFzLdOylIIua94ZlnYNWElSSNZ2nFRHGgbyqhYIYj4IMV1nNrh11bL6PgmW9Dq6pfz2KGrbrBMBJPRSkzZ imported-openssh-key
该注释以我尝试通过 SSH 连接的 theuncated/tail 输出结束，但是我运行了该命令，-vvv所以它很长。

答案1
我通过使用 gcloudsdk 并用 来监控它来解决了这个问题procmon。
首先使用 gcloud SDK 创建 SSH 连接：
例如ssh instance-1 --zone=us-central1-a
这将创建一个名为的文件。使用 PuttyGen 打开此文件，并通过单击>“导出 OpenSSH 密钥”~/.ssh/google_compute_engine.ppk使用它来创建 OpenSSH 密钥。Conversions
该文件可用于使用 连接到实例ssh -i {filename} {username}@{host}。
