부제: ssh login 할때 비밀번호 없이 인증키를 사용하여 로그인 하기. [요약 설명] A-site 에서 B-site 로 접속시 비밀번호 없이 접속 하려면 A-site에서 인증 서를 만든 다음 B-site에 복사해 주면 된다. A-site : titan B-site : hyperion [nadia@titan ssh_key]$ ssh-keygen -t rsa [nadia@titan ssh_key]$ scp ~/.ssh/id_rsa.pub hyperion:./.ssh/authorized_keys [실행 예제] [nadia@titan ~]$ ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/nadia/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/nadia/.ssh/id_rsa. Your public key has been saved in /home/nadia/.ssh/id_rsa.pub.
