VS代码SSH远程连接问题

Question

在过去的一个月里，我一直在使用VS Code，并在家里用MacBookPro远程连接，以完成一个大学项目，但由于某种原因，它将不再连接到Computer Lab Server。不知道为什么会发生这种情况，但它今天刚刚停止工作。我试着重新安装vs代码，也把它安装在我妻子的电脑上，但它仍然无法通过远程ssh连接。不知道为什么会发生这种情况，但现在我没有办法调试我的代码，只能通过mac上的终端应用程序使用emacs编辑所有内容。从昨晚到今天早上，我没有做任何改变。。我仍然可以通过ssh从终端进入Computer Lab服务器。Bellow是一些在尝试使用扩展名remotessh进行连接时似乎会重复的日志。

如果能在这方面提供任何帮助，我们将不胜感激，或者有其他IDE可以通过ssh轻松远程连接吗？

我的日志：

Answer 1

关键信息在行提供

[17:09:22.713] > Acquiring lock on /home/students/tkwilk/.vscode-server/bin/93c2f0fbf16c5a4b10e4d5f89737d9c2c25488a3/vscode-remote-lock.tkwilk.93c2f0fbf16c5a4b10e4d5f89737d9c2c25488a3

如果您可以将ssh放入服务器并通过删除文件

rm -rf /home/students/tkwilk/.vscode-server/bin/93c2f0fbf16c5a4b10e4d5f89737d9c2c25488a3/vscode-remote-lock.tkwilk.93c2f0fbf16c5a4b10e4d5f89737d9c2c25488a3

然后重新启动vscode并尝试连接，一切都会好起来的。

Answer 2

在两台服务器上遇到相同的问题，原因有两个：

1. 一个问题通过参考这个问题得到了解决：#2805

   • 命令调色板->选择"；远程SSH：终止主机上的VS代码服务器">
   • 删除目录"~/"。vscode服务器"；在远程服务器上

2. 其他问题是由该服务器上的存储配额不足引起的。当配额增加时，这个问题就自动解决了。

Answer 3

我看到的大多数microsoft/vscode-remote-release，如问题2901，都是关于目标服务器上出现故障的符号链接。

如果您可以在命令行中使用ssh，请尝试重命名/home/students/tkwilk/.vscode-server，以便通过VSCode强制完全重新安装ssh远程插件。

mv ~/.vscode-server ~/.vscode-server-old

尝试通过VSCode连接到该服务器，并在尝试重做完整的VSCode服务器SSH设置时查看问题是否仍然存在。

Answer 4

我发现了一个新的原因，但可能很罕见：

在发现这个问题之前，我已经更新和修改了远程虚拟机的linux内核，并修改了位于/include/linux/uts.h中的UTS_SYSNAME；

#define UTS_SYSNAME "Linux Clstilmldy-LZM"
// #define UTS_SYSNAME "Linux"

所以我遇到了这个问题，但我从未找到可行的解决方案；

我仔细查看了vscode的输出，发现vscode remote-ssh:Unsupported platform: Linux Clstilmldy LZM；

[16:38:25.333] SSH Resolver called for host: Ubuntu

[16:38:36.086] > Unsupported platform: Linux Clstilmldy-LZM
[16:38:36.096] > ac25402ecd5f: start

我猜vscode remote ssh不识别Linux、Mac和Windows以外的系统名称，所以我把这一行改回来了。

我重新编译并安装内核。

好吧，我解决了问题。

Answer 5

另一个答案，因为这些都不适用于我。请尝试在VSCode中关闭以下设置：remote.SSH.useFlock
