저는 아직 이것에 대해 꽤 낯설기 때문에 제가 겪고 있는 문제를 설명하려고 노력할 것입니다. scp원격 서버에 파일을 보내려고 하는데 Permission denied (publickey)verbose()를 사용하여 명령을 실행하면 -v끝까지 오류가 발생하지 않습니다. 대상 디렉터리는 scp에 사용하는 사용자의 rwx입니다. 돕다!

아니면 파일을 전송하는 또 다른 덜 안전한 방법이 있습니까? 점점 지루해지고 있어요.
답변1
로 명령 을 실행 중이므로 scp일반 사용자로 실행되고 있지 않습니다 sudo. root로컬 시스템의 루트 사용자에게는 자체 SSH 키 세트가 있으므로 명령을 실행할 때 명령 sudo scp...은 scp루트의 SSH 키에서 키를 찾습니다. 그러나 legoman.
따라서 사용자로서 다음을 시도해 보십시오 legoman.
scp -v /home/legoman/Documents/index.html legoman@ip:/home/legoman/Documents
그래도 실패하면 원격 컴퓨터의 관리자에게 연락하여 사용자가 해당 컴퓨터에 연결할 수 있도록 설정하도록 요청해야 합니다.
일반적으로 현재 시스템의 루트 사용자만 원격에 액세스할 수 있는 경우가 아니면 scp루트 로 실행하고 싶지 않을 것입니다 .ssh
