为什么SCP在这种情况下写入0字节？

Question

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，但它似乎在做一些握手......当我 scp 到网络中的盒子时，它工作正常 =/

为什么 scp 在这里不起作用？

我检查了远程框的权限看起来没问题...

没有错误信息...

什么是“Bash Src 已加载！” 在详细输出中？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“你的外壳干净吗？”）但使用 scp 而不是 rsync。
