내 공개 키(from)를 서버의 파일(from) ~/.ssh/id_rsa.pub에 추가했는데 , 이는 적어도 마지막 Ubuntu 업데이트까지 제대로 작동했습니다(오늘날에도 Linux Mint 시스템에서 - 다른 키이지만 rsa도 있음).~/.ssh/authorized_keysssh-rsa
Ubuntu에서 사용하고 있습니다 OpenSSH_7.2p2 Ubuntu-4ubuntu1, OpenSSL 1.0.2g-fips 1 Mar 2016(Mint 시스템의 SSH 버전을 모릅니다. 서버가 CentOS를 실행하는 것 같습니다).
내가 뭘 잘못했나요?
그냥 재미로 다음을 추가했습니다.
# http://www.openssh.com/legacy.html
Host xxxxxxx.xxx
HostkeyAlgorithms +ssh-dss
도착하다 .ssh/config.
~/.ssh/authorized_keys연결은 성공했는데 공개 DSA 키가 없어서 비밀번호를 계속 입력해야 합니다 .
16.04 LTS그렇다면 RSA를 사용하는 SSH가 내 Ubuntu 시스템 에서 작동하지 않는 이유는 무엇입니까 ?
