Ошибка в списке каталогов ТОЛЬКО в порту 22 (SFPT)

Я внезапно получаю эту ошибку, используя SFTP :

Status: Connecting to 64.207.146.82... Response: fzSftp started Command: open "root@64.207.146.82" 22 Command: Pass: ********* Status: Connected to 64.207.146.82 Status: Retrieving directory listing... Command: pwd Response: Current directory is: "/root" Command: ls Status: Listing directory /root Error: Connection timed out Error: Failed to retrieve directory listing 

Я пытался использовать FileZila, Cyberduck, Shell (Терминал), тот же результат. Тем не менее, сегодня он работал нормально (всего несколько секунд) в пассивном режиме.

Это сообщение в Cyberduck :

I/O Error: Unexpected end of sftp stream. 

На моем компьютере не активирован брандмауэр, и после изменения некоторых параметров в сети я прохожу тест (как активный, так и пассивный):

Connecting to probe.filezilla-project.org Response: 220 FZ router and firewall tester ready USER FileZilla Response: 331 Give any password. PASS 3.6.0.2 Response: 230 logged on. Checking for correct external IP address Retrieving external IP address from http://checkip.dyndns.org:8245/ Checking for correct external IP address IP 186.15.222.5 big-bf-ccc-f Response: 200 OK PREP 50185 Response: 200 Using port 50185, data token 386379933 PORT 186,15,222,5,196,9 Response: 200 PORT command successful LIST Response: 150 opening data connection Response: 200 Successful QUIT Response: 200 goodbye! Connection closed 

Сейчас я работаю в пассивном режиме.

Поскольку я работаю за маршрутизатором, я получаю свой внешний IP-адрес с http://checkip.dyndns.org:8245/

Я тестировал разные диапазоны портов.

SSH работает отлично, но SFTP застревает в части каталога листинга.

sftp root@64.207.146.82 root@64.207.146.82's password:  Connected to 64.207.146.82. sftp>ls 

Делаем некоторую отладку из ssh:

РЕШЕНИЕ :

После того, как вы войдете в систему / подключитесь к серверу, используя SSH:
