I got 2 pi’s running osmc (pi2, pi3b), and both of them had till recently ufw running on them. Today i noticed that i could see my pi from my pc to chromecast to.I thought that is weird…maybe ufw is down. So i did ufw status on my pi2 and got:
root@pi2:~# ufw enable
Command may disrupt existing ssh connections. Proceed with operation (y|n)? y
Firewall is active and enabled on system startup
root@pi2:~# ufw status
Status: inactive
root@pi2:~#
on my pi3 i got:
root@KodiPi3:~# ufw status
Status: inactive
root@KodiPi3:~# ufw enable
Command may disrupt existing ssh connections. Proceed with operation (y|n)? y
ERROR: problem running ufw-init
