问题描述

我正在尝试从我的本地机器上将一个文件从一个远程服务器复制到另一台远程服务器.这就是我想要做的

I'm trying to copy a file from one remote server to another remote server from my local machine. Here's what I'm trying to do

localA $ scp userB@remoteB:/path/to/file userC@remoteC:/path

问题是我需要在远程机器上为 userB 和 userC 传递两个密码.

The problem is that I need to pass two passwords for both userB and userC on the remote machines.

根据 Garron 以上应该可行，但我的许可被拒绝.

According to Garron the above should work, but I got permission denied.

Permission denied (gssapi-keyex,gssapi-with-mic,publickey,keyboard-interactive).
lost connection

有什么建议吗?

如果 remote1 和 remote2 在同一网络上，则上述情况成立.

The above is true if remote1 and remote2 are on the same network.
