クライアントからサーバーに ftp を実行できません。仮想マシンからサーバーにpingを送信でき、sshはできますが、ftpはできません。私が使っている基本的なマシンはUbuntu 14.04です。ifconfig出力は次のとおりです。

サーバーでは、次の構成でVM RHEL 6をデプロイしました。
Ipaddr: 192.168.122.217
NATプロトコルはネットワークを設定するときに使用されます。どんな助けでも大変感謝します。
答え1
ftpRHEL 6では、これらの安全でないプロトコルはデフォルトでインストール/アクティブ化されません。
yum install proftpdftpがインストールされます。
