오늘 Sierra로 업데이트 한 후 sshUbuntu 14.04 상자에 연결할 수 없습니다.
포트 22와 협상 할 수 없습니다. 일치하는 암호가 없습니다. 그들의 제안 : blowfish-cbc
Apple이 OpenSSH 버전을 업그레이드 했으며이 Ubuntu 버전에서 사용되는 암호를 더 이상 지원하지 않는다고 생각합니다. 그러나 나는 어느 쪽을 다시 작동하도록 구성하는 방법을 잃었습니다.
나는 이미 성공적으로 시도했지만 ssh -c blowfish-cbc <my_host>(양측이 그것을 지원하는 것으로 보임) 그것이 안전한 선택인지 확실하지 않습니다.
편집하다
출력은 다음과 같습니다 ssh -vvv -c blowfish-cbc <hostname>
