当我尝试使用scp或传输文件时出现错误rsync，但我可以使用 WinSCP 传输文件，它使用 SCP 协议。
我在 Windows 11 和 WSL2 上运行 WinSCP scp rsync，当我在 Windows 上运行它们时，输出与此相同。
当我使用scp
$ scp foo [email protected]:~/
scp: Connection closed
当我使用rsync
$ rsync -av foo [email protected]:~/
sending incremental file list
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(231) [sender=3.2.7]
这是 WinSCP 的日志：

OpenSSH_9.6p1，OpenSSL 3.2.1 2024 年 1 月 30 日
...
debug1：发送子系统：sftp
您正在使用的最新版本scp，它默认内部使用 SFTP（而不是 SCP）。
您的服务器似乎不支持 SFTP 协议。
如果你想使用 SCP 协议scp，请添加-O转变到它的命令行：
scp -O foo [email protected]:~/
不过，请考虑修复您的服务器以支持 SFTP。
