Когда я пытаюсь подключиться к своему ftp-серверу через winscp, я впервые получаю сообщение об ошибке "Команда недопустимого порта", и это происходит, когда в нем перечислены файлы корневого каталога (/). Я не уверен, как избавиться от этой ошибки, проверял исходный сценарий (предполагая, что есть некоторый сценарий инициализации), но не смог найти правильный источник или ссылки для изучения.
Скопированный контекст журнала для справки.
К вашему сведению: FileZilla работает без проблем. Пожалуйста, пролите свет на эту проблему!
