[解決済み] Forward X11 に失敗しました。ネットワークエラー。接続が拒否されました

質問

OSがCentOS6.3のVPSを持っています。私は実行したい startx PuTTYとXmingを使用しています。

しかし、このようなエラーが発生します。

以下は私の sshd_config をVPS上で実行します。

上記のエラーの原因は何でしょうか？

lilydjwgの回答によると、"X display location"を記入し、再度試しましたが、やはりおかしいです。

解決方法は？

PuTTY は X サーバーがどこにあるか見つけることができません。(LinuxのsshはXの下で動いているので、この問題はありませんから、そちらを使うだけです) X display location"の後の空欄に、Xmingサーバーのアドレスを記入してください。

または、次のようにします。 MobaXterm . Xサーバを内蔵しています。
