Привет.
Я не настоящий сварщик, а так пет проект.
Вобщем взял на ovh vps-ку с дебиан 12 и натравил на неё nmap:
sudo nmap -sV ************

21/tcp open ftp
22/tcp open ssh
1723/tcp open pptp

Nmap done: 1 IP address (1 host up) scanned in 1.14 seconds
И это говорит, что кроме ssh, открыты порты 21(ftp). 1723(pptp) и 5060(sip).
Возможно, но я не могу найти их на сервере:

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
36 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
При том, что на домашней виртуалке, на которой я тестировал деплой проекта nmap выдаёт вполне то, что ожидается:

Собственно, как обычно, вопроса два:

- что делать?
