Windows10에서 내장된 SSH 서버/클라이언트를 사용하려고 합니다.
실행할 때 SSH가 잘 열립니다. ssh localhost또는 ssh user@local_IP_address(키 기반 인증을 사용하고 있습니다.)
이제 내 라우터에 포트 22를 전달했고 외부 IP를 통해 SSH에 액세스하려고 합니다.
ssh user@remote_IP_address
나는 얻다
kex 프로토콜 오류: 유형 30 seq 1
내가 달릴 때
ssh user@remote_IP_address -vv
나는 얻다

퍼티를 사용하여 연결을 시도했는데 kex 알고리즘을 다시 정렬하여 Diffie-Hellman group1이 마지막이 되도록 해도 비슷한 오류가 발생합니다.
오류 메시지는 말한다
ECDH 응답을 기대할 때 예기치 않은 패킷을 받았습니다. 30(SSH2_MSG_KEX_ECDH_INIT)을 입력하세요.
답변1
Microsoft 보안 필수 요소 또는 Windows 방화벽으로 인해 SSH 연결 인터페이스로서의 퍼티가 실패하는 경우 가상 머신에서 거의 드문 경우가 있지만 유형 오류 문자열과 관련하여: Kex 프로토콜 오류: 유형 30 seq 1 오류가 발생하는 것으로 추정됩니다. Diffie-Hellman 그룹 교환에 의해 정의됩니다. KEX는 절대 사용되지 않으므로 SSH 사용을 위해 클라이언트와 서버 모두에서 업데이트해야 하며 소프트웨어로서 일부 퍼티 터미널도 업데이트해야 합니다. 다음 정보가 도움이 될 수 있습니다. http://forum.filezila-project.org/viewtopic.php?t=37469 https://github.com/michaellukashov/Far-NetBox/issues/156
