我有一台内置有 openssh 服务器的远程 Windows 机器。我尝试将远程 Windows 中scp名为“我的主目录”的文件夹复制到本地下载：0
scp -r micro:0 Downloads/
本地主机中的结果：
Downloads/0
然后我1在0远程窗口中添加了子文件夹并scp再次运行。本地主机中的结果：
Downloads/0
└── 1
我继续添加子文件夹，直到7。本地主机中的结果：
Downloads/0
└── 1
└── 2
└── 3
└── 4
└── 5
└── 6
└── 7
然后我添加了第 8 级。scp命令失败，没有创建8文件夹。输出：
Executing: program /usr/bin/ssh host micro, user (unspecified), command scp -v -r -f 0

这个问题似乎与长文件路径无关。我尝试移动0到~/a/b/c/d/e/f/g/h/远程，scp -r micro:a/b/c/d/e/f/g/h/0 Downloads/没有文件夹也能正常工作8。
如何scp在源路径下使用超过 8 个子目录级别？
答案1
这是你的错误信息：
debug1: Exit status -1073741571
错误代码-1073741571是十六进制错误代码 0xC00000FD 的有符号十进制表示，在 Windows 中代表堆栈溢出或堆栈耗尽。这通常发生在递归太深且程序的堆栈太小时。
问题是问题出在服务器上还是客户端上。
我认为您在远程服务器上使用了 Windows 内置应用程序。我建议用 OpenSSH 服务器替换它。
如果问题消失，你就知道问题出在服务器上，现在已经解决了。如果没有消失，那么你需要更换客户端软件。
