Question

我正在尝试使用Remote-SSH扩展来编辑Debian服务器上的文件。 SSH连接已正确建立，但随后出现错误消息：

Failed to connect to the remote extension host server

还有日志：

我正在其他几台服务器上使用远程ssh连接，但从未遇到此错误。我已经测试了一些从网络上搜集到的东西，但到目前为止没有任何工作。

有人可以启发我解决问题的原因或可能的解决方案吗？谢谢！

Answer 1

Delete '~/.vscode-server' folder on your server, and try reconnect.

不确定Debian服务器，但这在Ubuntu 18.04上有效

Answer 2

[13:19:04.227] > channel 3: open failed: administratively prohibited: open failed

您要连接的远程服务器拒绝为您执行端口转发。假设远程服务器是OpenSSH，则可以在远程服务器上的两个地方进行配置：

服务器可能配置为不允许通过sshd_config选项PermitOpen或DisableForwarding选项进行端口转发。
如果您正在使用ssh密钥进行身份验证，则可以通过authorized_keys选项PermitOpen或restrict禁用转发。

Answer 3

将sshd_config中的AllowTcpForwarding从no更改为yes，然后重新启动sshd对我来说是可行的。

经过Raspbian GNU/Linux 10 (buster)

的测试

Answer 4

FWIW;我遇到了同样的问题，重新启动似乎可以解决问题。
