저는 이 서버를 처음 접했습니다. 이것은 제가 직접 설정한 두 번째 서버입니다. 간단하고 간단해야 하는데 이 오류가 발생합니다.
주위를 둘러보았지만 솔루션이 내 상황에 맞지 않습니다.
.pem
AWS에서 인스턴스를 생성할 때 방금 다운로드한 파일을 제공했는데도 여전히 이 오류가 발생합니다.
ssh -vvv -i ~/.ssh/transa.pem [email protected]
디버그 출력은 다음과 같습니다.

다른 계정에서 사용하는 다른 파일이 있는데 .pem
문제가 없습니다. 두 파일 모두 using 을 사용하여 로드됩니다 ssh-agent
. .bashrc
이 문제와 관련이 있는지는 모르겠습니다. 하나는 잘 작동하는데 다른 하나는 작동하지 않는 이유는 무엇이며 어떻게 작동하게 합니까?
Windows 10에서 Linux 쉘( wsl
) 을 사용하고 있습니다.
답변1
EC2 키 페어 파일에는 제한된 권한이 있어야 하며, 이 작업을 수행하려면 관리자 권한이 필요합니다. 관리자 권한이 없으면 오류가 표시되지 않을 수 있습니다. 따라서 권한이 변경되었다고 생각할 수도 있습니다.
sudo su
chmod 400 ~/.ssh/transa.pem
답변2
제 경우에는 사용자 이름을 추가해야 했기 때문이었습니다.
사용자 이름 없이 SSH를 사용해 보세요.
$ ssh -vvv -i ~/.ssh/aws.pem 52.88.251.23
Error message: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
다음을 사용하십시오(기본 사용자 이름 ec2-user
):
ssh -v -i ~/.ssh/aws.pem [email protected]
