そのため、 Ubuntu 14.04.3 LTS サーバー (32 ビット)で proFTPD (www.webmin.com の最新のものである必要があります) (webmin1.760 を使用) を実行しています。
管理者のユーザー名とパスワードがあれば、
別の自宅の PC から FileZilla を使用して FTP サーバーにアクセスできますが、ファイルのアップロード/変更/作成は許可されていません。
以下は、削除時にFileZilla に表示されるエラーです。

Command: DELE index.html

グーグルを試してみましたが、一般的なエラーではないようで、 「etc/proftpd/proftpd.conf」

FileZilla に表示されるエラー以外の手がかりさえ見つからないため、自分で処理するのは非常に混乱します。
FTP はサーバーを構成するために重要です。何か手掛かりを教えていただければ大変助かります。ありがとうございます。
また、別の FTP サーバーを使用することもできますが、何か提案はありますか?
