What is the difference between starting ufw service and enabling ufw?
Is there any difference between the command
service ufw startand the command
ufw enable2 Answers
When ufw is disabled, service ufw start will not work. To check this, after you run sudo ufw disable then run sudo service ufw start it should show that the firewall is still inactive.
Example:
terrance@ubuntu-HP:~$ sudo ufw status
Status: active
terrance@ubuntu-HP:~$ sudo ufw disable
Firewall stopped and disabled on system startup
terrance@ubuntu-HP:~$ sudo ufw status
Status: inactive
terrance@ubuntu-HP:~$ sudo service ufw start
terrance@ubuntu-HP:~$ sudo ufw status
Status: inactive
terrance@ubuntu-HP:~$ sudo ufw enable
Firewall is active and enabled on system startup
terrance@ubuntu-HP:~$ sudo service ufw stop
terrance@ubuntu-HP:~$ sudo ufw status
Status: inactive
terrance@ubuntu-HP:~$ sudo service ufw start
terrance@ubuntu-HP:~$ sudo ufw status
Status: activeHope this helps!
I believe so.
ufw enable/disable will actually enable or disable the ufw service. So it won't start even after a reboot, and using service ufw start won't start it either.
service ufw start/stop/restart just deals with the service power management. You can stop the service temporarily, restart it to reload some configs, or start it after stopping it.
service ufw stop may stop the service, but rebooting (and maybe relogging) will just cause it to start again.
