Debian GNU/Linux 9 を実行する Debian マシンの仮想マシンが 2 台あります。次のプロセスを試してみましたが、まだパスワードの入力を求められます。 10.21.12.74ポート45962 ssh2 [preauth]のテスト用に延期された公開鍵のため失敗します。

OpenSSH_7.4p1 Debian-10+deb9u7、OpenSSL 1.0.2uがあります。 2019年12月20日

クライアントコンピュータで、公開鍵ペアと秘密鍵ペアと呼ばれるデフォルトのSSH鍵ペアを作成しました。

$ssh-keygen 

次に私は-

ssh-copy-id [email protected]

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh '[email protected]'"
and check to make sure that only the key(s) you wanted were added.

動作方法は、次のコマンドを使用してクライアントでssh-agentを終了することです。

SSH-エージェント-K

次に、マシンを再起動する必要があります。良い方法はありませんか？
