几天前，我能够scp使用 cygwin 从我的 windows server 2003 复制到远程服务器id_rsa，但现在使用它（）似乎不起作用。我没有安装或删除任何 cygwin 包。scp (id_rsa.pub location) [email protected]scp
我仍然可以自动使用连接到服务器ssh。在同一台服务器上，同时在其他 Ubuntu 机器上工作，scp并且运行正常。使用命令ssh时它甚至不会提示输入密码。scp
scp -v c:/outfiles/[email protected]:~/temp/headers.csv
Executing: /usr/bin/ssh -x -oClearAllForwardings=yes -n -v -- c scp -v /outfiles/headers.csv [email protected]:~/temp/headers.csv

我想在这里补充的另一个问题是：
我可以启动 cron 服务，但 cron 作业不起作用。(ORPHAN)no password set在使用 cronlogs 查询时，我收到 cron 作业的错误提示。我的 Cygwin 设置似乎存在一些问题，但我无法诊断它们。除了在cygwin 常见问题解答谷歌搜索了将近两天，情况仍然一样，卡住了。基本上，我正在尝试使用scp任何其他选项来自动执行文件传输，这很有帮助，我已经卡了很长时间了。
这可能不是一个好主意，但我还是要问这个问题。是否可以怀疑防火墙是导致此问题的原因，如果是，如何验证？我曾在某处读到过，但没有继续读下去，理由是使用相同的端口号 22 成功，这种 netstat理由是合理的，也可能是错误的。ssh
