无法与 "hostname" 建立连接。（VSCode 中的远程 SSH 问题）(CentOS7)

Question

[已解决！！]

服务器OS:分OSLinux7
VSCode 版本（本地）： 1.59.1

我通过 ssh 连接到我的服务器

ssh ...@ln01.twcc.ai

我尝试通过本地打开 VSCode，并使用 Remote-SSH -> 连接到 SSH -> 输入 ...@ln01.twcc.ai

然后得到Could not establish connection to "@ln01.twcc.ai".错误块输出如下

总结

当我尝试通过本地 VSCode 进行远程 ssh 时，收到 与 SSH 断开连接 错误

Error Block

Answer 1

我通过编写 SSH 配置文件解决了这个问题

如果您通过 ssh 连接到服务器，例如：

ssh Amy@123.456.78.999 -p 22

那么配置文件将是：

Host MyHostName
    HostName 123.456.78.999
    User Amy
    Port 22

参考：https://github.com/microsoft/vscode-remote-release/issues/3968

Answer 2

尝试删除保存在 known_hosts 文件中的指纹（对应于此特定连接的单行 - 而不是整个文件）。如果在 Windows 中，则放在 C:\Users\<your_user_name>\.ssh\known_host 中，而对于 Linux，则放在 /home/<your_user_name>/.ssh/known_hosts 目录中。

因为更详细，你可能也想检查这个。
