나는 매우 이상한 상황에 직면했습니다.
SSH를 통해 특정 사용자를 다른 호스트에 연결하는 데 몇 가지 문제가 있습니다. 따라서 이 사용자에 대한 모든 SSH 키를 간단히 다시 초기화하려고 합니다. 그래서 나는 이렇게 했습니다:
cd ~/.ssh
rm *
ssh-keygen -t rsa
cp id_rsa.pub authorized_keys
chmod 600 authorized_keys
이것이 내 SSH 연결을 완전히 재설정할 것이라고 생각합니다. 하지만 지금 내가 이렇게 하면:
ssh localhost
나는 얻다:
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
만약 내가한다면:
ssh -v localhost
이해합니다:

나는 무슨 일이 일어나고 있는지 이해하지 못합니다. 제가 보기에는 localhost에 대한 간단한 ssh가 제대로 작동할 것 같습니다.
어떤 단서가 있나요? 감사해요!
