By networking stops means that I can not establish a connection with the Lemaker BananaPi Pro on any port so I can't get a SSHed shell, can't access the VPN server, etc... It behaves like someone has plugged the network cable.
Putting "ufw.service" was a guess, but I've not rebooted the OS yet with that in place. root@loki:~# iptables --version iptables v1.8.4 (legacy) root@loki:~# uname -a Linux loki 5.10.60-sunxi #21.08.2 SMP Tue Sep 14 16:28:44 UTC 2021 armv7l armv7l armv7l GNU/Linux root@loki:~# fail2ban-client --version Fail2Ban v0.11.1 OS in use obtained from here: https://www.armbian.com/banana-pi-pro/ I will try a reboot and see what happens. Will report result back here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1956029 Title: ufw remains inactive at boot time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ufw/+bug/1956029/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
