비밀번호 없는 SFTP를 사용하여 파일을 전송하려고 합니다. 지난주까지 작동했고 동일한 키를 사용하여 다른 서버에서 파일을 전송할 수 있었습니다. 그러나 이것은 sftp -v -oIdentityFile=/home/n123456/.ssh/id_rsa_ability 명령을 입력한 후 즉시 연결을 닫습니다.[이메일 보호됨]. 공개 키를 사용하여 인증하고 있습니다. 자세한 로그를 PFB합니다.

답변1
서버가 SFTP 하위 시스템을 초기화하지 못했습니다.
일반적으로 이에 대해 할 수 있는 일은 많지 않습니다. 서버를 수정하려면 서버 관리자에게 문의하세요.
이것은 아마도 당신의 열쇠와 아무 관련이 없을 것입니다.
