无法在 Google 云实例上 SSH

Question

我被 sshed 到我的 gcloud 实例。我突然退出并出现以下错误：

Timeout, server 104.198.148.233 not responding.
ERROR: (gcloud.compute.ssh) [/usr/bin/ssh] exited with return code [255]. See https://cloud.google.com/compute/docs/troubleshooting#ssherrors for troubleshooting hints.

再次尝试时，我得到以下信息：

OpenSSH_7.2p2, LibreSSL 2.4.1
debug1: Reading configuration data /Users/aapa/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 20: Applying options for *
debug1: Connecting to 104.198.148.233 [104.198.148.233] port 22.
debug1: Connection established.

debug1: identity file /Users/aapa/.ssh/google_compute_engine-cert type -1
debug1: Enabling compatibility mode for protocol 2.0
debug1: Local version string SSH-2.0-OpenSSH_7.2

如何才能找到问题？我应该采取什么步骤。

Answer 1

错误是“key_load_public：没有这样的文件或目录”。超时错误建议阅读故障排除指南：https://cloud.google.com/compute/docs/troubleshooting#ssherrors。

该指南说错误的可能原因可能是磁盘已满或网络问题。你的磁盘满了吗？您可以通过从 SSH 控制台访问您的实例来检查。
