パスワードなしのSSHを使用して、ユーザ名naveedと同様にrootとして仮想サーバにログインできます。そのために、私はリモートのsshディレクトリに秘密鍵と公開鍵を作成し、authorized_keysファイルに公開鍵を追加しました。 しかし、私はssh comquestをするときにパスワードを尋ねます。 Comquestは私のリモートサーバのホスト名です。以下はリモートサーバ上のSSHに関する奇妙な問題
は私の権限情報です：
[email protected]:~$ ls ~/.ssh
authorized_keys known_hosts local local.pub
[email protected]:~$ stat -c "%a %n" ~/.ssh
755 /home/naveed/.ssh
[email protected]:~$ stat -c "%a %n" ~/.ssh/authorized_keys
644 /home/naveed/.ssh/authorized_keys
私は以下
