SUSE에서 openBSD sshd를 사용하여 ssh를 통해 실행된 명령에 대한 출력이 없습니다.

SSH를 통해 명령을 실행해 보았지만 응답을 받지 못했습니다. 서버 A는 Solaris 시스템이고 서버 B는 OpenBSD sshd를 사용하는 SUSE Linux입니다. 확인됨

2. https://www.openbsd.org/papers/auug2002-ssh.pdf
3. https://superuser.com/questions/792070/commands-over-ssh-not-having-output

및 기타 소스를 사용했지만 해결할 수 없었습니다.

내가 시도하는 명령은 (bash에서) 다음과 같습니다.

    ssh -v -i .ssh/id_rsa -p1234 user2@abcdefg 'ls -al'

(따옴표와 큰따옴표 없이 시도)

편집: SSHd 측에서 Loglevl을 활성화하고 인증 파일에서 다음을 얻었습니다.
