SSH가 다른 키를 가져오고 있습니다.

SSH가 다른 키를 가져오고 있습니다.

SSH 유틸리티가 Known_hosts로 키를 추가하고 작업을 수행하는데 다음 오류가 발생합니다.

ubuntu@${addr}: Permission denied (publickey).

나는 이 코드를 가지고 있습니다 :

#!/usr/bin/env bash

ssh-add -D
ssh -vvv -i 'my.pem' "ubuntu@${addr}"

출력은 다음과 같습니다.

All identities removed.

답변1

솔직히 말해서 저는 ssh 유틸리티를 별로 좋아하지 않습니다. 부엌 싱크대 전체를 집어던졌기 때문에 어떻게 고쳤는지 기억이 나지 않지만 다음은 작동합니다.

    chmod 600 my.pem
    chmod 600 my.pem.pub
    
    ssh-add -D
    
    ssh -vvv -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null \ 
       -i '${pemPath}.pem' "ubuntu@${addr}"

아 예, 제가 가진 또 다른 문제는 Authorized_keys에 이것이 있다는 것입니다

ssh-rsa ssh-rsa AAAAB3NzaC1yc2EAAA....(omitted)...a0b51 me@myhost

내 파일에는 두 개의 "ssh-rsa ssh-rsa..."가 있는데 (분명히) 하나만 필요하므로 파일에 형식 오류가 없는지 확인하십시오.

다음과 같아야 합니다.

ssh-rsa AAAAB3NzaC1yc2EAAA....(omitted)...a0b51 me@myhost
