ProFTP не возвращает список каталогов

Итак, я установил ProFTP на свой сервер Ubuntu 10.10. Используя FileZilla, я могу подключиться и пройти аутентификацию, но не могу получить список каталогов. Вот несколько последних строк, которые мне вернули:

Status: Connected
Status: Retrieving directory listing...
Command:    PWD
Response:   257 "/home/todolist" is the current directory
Command:    TYPE I
Response:   200 Type set to I
Command:    PASV
Error:  Disconnected from server: ECONNABORTED - Connection aborted
Error:  Failed to retrieve directory listing

Я ничего не менял в конфигурации, так что мне следует изменить / установить, чтобы я мог правильно использовать FTP?

Моя конфигурация:
