我正在尝试将我的 ssh 密钥从我的本地虚拟机复制到另一个盒子,一切似乎都正常,但是当我检查远程盒子时,文件不在那里......
Transferred: stdin 0, stdout 0, stderr 0 bytes in 0.0 seconds
scp 看起来没有写任何东西,但我不知道为什么!
我想可能是因为内部网络没有暴露,也许它无法通过 scp 与远程盒子通信,但它似乎正在进行一些握手...当我通过 scp 连接到网络中的一个盒子时,它工作正常 =/
为什么 scp 在这里不起作用?
我已经检查过远程盒子上的权限看起来没问题......
没有错误消息...

答案1
详细输出中的“Bash Src is loaded!”是什么意思?它来自你的 ~/.bashrc,不是吗?让它消失。
基本上,它与此相同:Rsync 似乎与 .bashrc 不兼容(导致“你的 shell 干净吗?”)但使用 scp 而不是 rsync。
嘿,常见问题解答中甚至还有一个条目:https://www.complang.tuwien.ac.at/doc/openssh-server/faq.html#2.9
答案2
如果你无法转账任何文件,这可能是由于您的 .bashrc(或等效文件)在非交互式登录(即 rsync、scp 等)期间做了不该做的事情;在过去的糟糕日子里,'stty' 因造成此类问题而臭名昭著。请参阅http://theory.uwinnipeg.ca/localfiles/infofiles/bash/bashref_54.html有关如何检查你的 shell 是否是交互式的的一些提示。
答案3
我在应用 ssh 选项时遇到过这个问题RequestTTY force
。例如,在我的情况下,我忘记了在我的 中启用了该选项~/.ssh/config
。
在这种情况下,添加-o RequestTTY=no
命令scp
将解决该问题。
