암호가 없는 SSH localhost가 Fedora 14에서 작동하지 않습니다.

tag-icon • tag-icon ssh fedora rhel
암호가 없는 SSH localhost가 Fedora 14에서 작동하지 않습니다.

나는 다음을 실행한다:

$ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa 
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

그런 다음 sshd 로 /etc/ssh/sshd_config변경 하고 다시 시작하십시오.StrictModesno

나는 가지고있다:

$ ssh localhost
Agent admitted failure to sign using the key.
dev@localhost's password:

뭐가 문제 야? 비밀번호 없는 작업을 수행하는 방법은 무엇입니까 ssh localhost?

고쳐 쓰다:

~/.ssh/authorized_keys파일 및 폴더에 대한 권한을 설정해 보십시오 ~/.ssh/.

chmod go-w $HOME/.ssh
chmod 600 $HOME/.ssh/authorized_keys
chown `whoami` $HOME/.ssh/authorized_keys

내 경우에는 SELinux의 통과성 문제를 확인해야 했습니다.

ausearch -c 'sshd' --raw | audit2allow -M my-sshd
semodule -i my-sshd.pp
/sbin/restorecon -v /home/xxxxxx/.ssh/authorized_keys

Authorized_keys에 공개 키를 추가하세요.
