~ / .ssh 폴더에이 id_rsa가 있습니다. 그러나 그것은 단지 인증하지 않습니다. 복사하여 id_rsa가 아닌 다른 이름으로 바꾸면 작동합니다.

[qfan@mycomputer .ssh]$ ls -al id_rsa id_rsa_good

Connection to localhost closed.

“ssh localhost -i id_rsa”가 실패하고 ssh가 일반 비밀번호 로그인을 요청하기 시작합니다.

나는 -vvv를 사용했고 로그의 차이점은 다음과 같습니다.

[qfan@mycomputer .ssh]$ ssh localhost -i id_rsa_good -vvv 2> log1_good.txt
Enter passphrase for key 'id_rsa_good':

[qfan@mycomputer .ssh]$ ssh localhost -i id_rsa -vvv 2> log2_bad.txt
qfan@localhost's password:

[qfan@mycomputer .ssh]$ diff log1_good.txt log2_bad.txt

키 파일에서 암호 문구를 제거하려고 시도했지만 id_rsa라는 이름으로 여전히 작동하지 않습니다.

그래서 무엇이 잘못 되었습니까?

——-편집하다——-

[qfan@mycomputer .ssh]$ file id_rsa
id_rsa: ASCII text
[qfan@mycomputer .ssh]$ cat id_rsa |head -n2
-----BEGIN RSA PRIVATE KEY-----
