2つのLinuxサーバーserver1：10.54.35.91 server2：10.54.35.27の間にパスワードのないSSHを設定しようとしています。
私のユーザー（ユーザー名：path86）としてserver1にログインし、ユーザーをgsadmin、su - gsdminに切り替え、別のサーバーのgsadminユーザーとしてsshingを試みました。サーバー1でssh-keygenを使用して鍵を生成し、それをサーバー2の認証済み鍵にコピーしました。
しかし、私のSSHが失敗し、その権限が返されました。詳細な出力は次のとおりです。助けてください。
[gsadmin@10-54-35-91 john]$ ssh -v [email protected]
