SSH는 협상할 수 없습니다. 일치하는 호스트 키 유형을 찾을 수 없습니다.

이전 클라이언트가 현재(v8.x) 버전의 openssh 서버에 연결할 수 없는 문제가 있습니다. 사용 가능한 키 유형 목록에 ssh-rsa, ssh-dss를 추가하는 데 익숙하지만 이 문제에는 적용되지 않는 것 같습니다.

우리 공급업체 중 하나가 고객이므로 로고를 전달할 수 있는 옵션이 없습니다. 연결을 시도하면 다음과 같은 메시지가 나타납니다.

Apr 16 20:57:13 server sshd[70429]: Unable to negotiate with 10.0.3.39 port 49100: no matching host key type found. Their offer: [email protected],[email protected],[email protected],[email protected],ssh-rsa,ssh-dss [preauth]

/etc/ssh/sshd_config.d/10-test.conf에 다음을 추가했습니다.

KexAlgorithms=+diffie-hellman-group1-sha1
[email protected],[email protected],ssh-rsa,ssh-dss
PubkeyAcceptedAlgorithms=+ssh-rsa,ssh-dss

"="가 없어도 효과가 없습니다. 디버그 출력은 다음과 같습니다.

내가 헤매고 있기 때문에 누구든지 어떤 아이디어가 있습니까?

감사해요!
