テストサーバ構築のためにサーバでFTPサーバを作りたく、様々なサイトを参考にvsftpdを使って構築したつもりだったのですが、いざFTPツールでアクセスしようとすると、ファイル構造は表示するもののファイルのダウンロード、アップロードが一切できません。
アクセスすると/home/ユーザ名/が表示されるのですが、その下も一切アクセスできません。
今回設定したい内容は、ユーザ(ryo)は/home/ユーザ名/ より上(すべて)にアクセス可能にしたいです。

# Example config file /etc/vsftpd/vsftpd.conf # # The default compiled in settings are fairly paranoid. This sample file # loosens things up a bit, to make the ftp daemon more usable. # Please see vsftpd.conf.5 for all compiled in defaults. # # READ THIS: This example file is NOT an exhaustive list of vsftpd options. # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's # capabilities. # # Allow anonymous FTP? (Beware - allowed by default if you comment this out). anonymous_enable=NO # # Uncomment this to allow local users to log in. # When SELinux is enforcing check for SE bool ftp_home_dir local_enable=YES # # Uncomment this to enable any form of FTP write command. write_enable=YES # # Default umask for local users is 077. You may wish to change this to 022, # if your users expect that (022 is used by most other ftpd's) local_umask=077 # # Uncomment this to allow the anonymous FTP user to upload files. This only # has an effect if the above global write enable is activated. Also, you will # obviously need to create a directory writable by the FTP user. # When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access #anon_upload_enable=YES # # Uncomment this if you want the anonymous FTP user to be able to create # new directories. #anon_mkdir_write_enable=YES # # Activate directory messages - messages given to remote users when they # go into a certain directory. dirmessage_enable=YES # # Activate logging of uploads/downloads. xferlog_enable=YES # # Make sure PORT transfer connections originate from port 20 (ftp-data). connect_from_port_20=YES # # If you want, you can arrange for uploaded anonymous files to be owned by # a different user.

##FTPツール(Cyberduck)でtxtファイルを転送しようとした際に発生したエラー
ポート開放(ファイヤーウォール)

詳しい方教えてください。
"/home/ユーザ名/" 上で ls -la を実行した結果を見せてもらえませんか?パーミッションやグループなどが関係している可能性があります。
追記しました。wwwというディレクトリを操作したいんです。もっと言うと、制限なくサーバ内のファイルへryoユーザはアクセスできるようにしたいんです。
なるほどです。FTPツールでアクセスした際に、U/Dができないとのことでしたが、たぶんFTPツール側にエラーが表示されていると思います。そちらも追加していただくことは可能ですか?
画像を追記しました。
たぶん、show details の部分にエラー内容が記載されていると思います。
show details の結果を追記しました。
