Эта проблема очень странная IMO. Я получил FTP-доступ к сайту, над которым я работаю, но, похоже, проблема с разрешениями. В FileZilla Если я пытаюсь отредактировать и повторно загрузить файл на сервер, я получаю ошибку « Permission denied доступе», но в то же время содержимое отредактированного файла стирается на сервере! Так что я попал в ситуацию, когда удаленный файл поврежден (все содержимое удалено - 0B!), Но у меня нет разрешения на его исправление.

Для большинства разрешений установлено значение 775 для папок и 664 для файлов.

  • Почему я могу получить permission denied ? Что не так с моими разрешениями?
  • Если мне действительно не дано разрешение на запись в файл, почему его содержимое удаляется?

Я прилагаю два журнала FileZilla, один с отключенной отладкой:

Проверяя исходный код FileZilla/PuTTY, становится ясно, что FileZilla действительно получила ошибку "Отказано в доступе" при попытке открыть файл для записи.

Если содержимое файла было удалено, несмотря на ошибку, это должно быть ошибкой / неправильной настройкой SFTP-сервера.
