Cisco 장치에 대한 SSH가 작동하지 않습니다.

내가 겪고 있는 문제는 서버를 최신 버전으로 업그레이드한 후 내 서버가 Cisco 장치에 SSH를 통해 연결할 수 없다는 것입니다.

ssh -vvv,잘 모르겠는 부분을 두 부분으로 만들었습니다 . 세부사항은 다음과 같습니다:

비밀번호 ctos와 비밀번호 stoc의 의미를 알고 싶습니다.

비밀번호:[email protected],aes128-ctr,aes192-ctr,aes256-ctr,[email protected],[email protected]

암호화폐 주식:[email protected],aes128-ctr,aes192-ctr,aes256-ctr,[email protected],[email protected]

또한 로그 끝에 다음 메시지가 표시됩니다. 10.44.39.202 포트 22와 협상할 수 없습니다. 일치하는 키 교환 방법을 찾을 수 없습니다. 그들의 인용문:diffie-hellman-group1-sha1

diffie-hellman-group1-sha1호스트 키 알고리즘에 추가할 수 있나요 ?

다음은 디버그 로그입니다.
