SFTP 시간 초과이지만 SSH는 정상적으로 작동합니다.

내 서버 설정에 sftp (또는 scp)를 할 수 없지만 ssh는 잘 할 수 있습니다. 둘 다 키 인증을 사용하고 있습니다.

내가 sftp를 할 때 그것은 영원히 멈추고 sftp 프롬프트를주지 않습니다.

다음은 내 자세한 sftp 실행의 출력입니다.

$ sftp -vvv dev@server

서브 시스템이 전송되고 있지만 여전히 프롬프트가 표시되지 않습니다. 아이디어가 있습니까?

편집하다

내가 추가하면 모든 것이 잘 작동합니다.

Forcecommand inetrnal-sftp

그러나 분명히 이것은 나를 위해 일반 ssh를 깨뜨립니다.
