2台のマシンがあり、1台はクライアントとして、もう1台はサーバーとしてセットアップされています。クライアントは、サーバーからコマンドを受信して応答するように設定されています。私は知っています...後方。Putty を使用してみましたが、接続が拒否され続け、クライアント/サーバー モデルが逆になっていることがわかりました。次のコードは機能しているようですが、データがクライアントに送信されたことを確認できません。ありがとう。
私のサーバープログラムは次のとおりです。

# to run in windows open command prompt and from directory that the
