Брандмауэр не будет работать в Ubuntu
Я использую Ubuntu 20.04, и брандмауэр не будет работать на моем устройстве.
Я получаю это сообщение при попытке запустить брандмауэр с systemctl start firewall :
root@agent:/usr/bin# systemctl start firewall
Job for firewall.service failed because the control process exited with error code.
See "systemctl status firewall.service" and "journalctl -xe" for details.
root@agent:/usr/bin# systemctl status firewall

firewall is not the service name to handle for the 'firewall' - we also don't use firewalld by default in 20.04 either.
The default firewall service in Ubuntu 20.04 is ufw - Uncomplicated Firewall.
You control ufw by commands on the command line.
To enable ufw just run sudo ufw enable and it should default to a permit-outbound deny-unrelated-inbound type policy.
To configure ufw please read the manpage of ufw - man ufw - for details on the commands, etc. to manipulate the firewall rules.
