為什麼SCP在這種情況下寫入0字節?
我正在嘗試將我的 ssh 密鑰從本地 vm 複製到另一個盒子,一切似乎都正常,但是當我檢查遠端框時,文件不存在……
Transferred: stdin 0, stdout 0, stderr 0 bytes in 0.0 seconds
scp 看起來它沒有寫任何東西,但我不知道為什麼!
我想也許是因為內部網路沒有暴露,也許它無法通過 scp 與遠端盒子交談,但它似乎正在做一些握手……當我 scp 到網路中的一個盒子時它工作正常 =/
為什麼 scp 不能在這里工作?
我已經檢查了遠端框的權限看起來沒問題…
沒有錯誤資訊…

什麼是“Bash Src 已載入!” 在詳細的輸出中?它來自你的 ~/.bashrc,不是嗎?讓它消失。
基本上,它與此相同:Rsync 似乎與 .bashrc 不兼容(導致“你的 shell 乾淨嗎?”)但使用 scp 而不是 rsync。
嘿,FAQ 中甚至還有一個條目:https ://www.complang.tuwien.ac.at/doc/openssh-server/faq.html#2.9
如果您無法傳輸任何文件,這可能是由於您的 .bashrc(或等效項)在非互動式登錄期間(即 rsync’ing、scp’ing 等)做了不應該做的事情;在過去糟糕的日子裡,‘stty’ 因引起此類問題而臭名昭著。請參閱http://theory.uwinnipeg.ca/localfiles/infofiles/bash/bashref_54.html以獲取有關如何檢查您的 shell 是否是互動式的一些提示。
