[Touch-packages] [Bug 1956029] Re: ufw remains inactive at boot time
Sorted out the issue. I've got systemd to also wait for ufw to load when starting fail2ban. Fail2ban issues a many iptables commands in rapid succession and then it's database of banned IPs is large it takes a considerable amount of time for the firewall to be initialised. In the meanwhile anything issuing iptables commands quite likely fail as is it not possible to have more than one instance of iptables active at any one time. ufw script completes its tasks quickly so makes sense to force that service to start before the fail2ban service. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ufw in Ubuntu. https://bugs.launchpad.net/bugs/1956029 Title: ufw remains inactive at boot time Status in ufw package in Ubuntu: Incomplete Bug description: I was advised to start a bug report (Comment 38): https://bugs.launchpad.net/ubuntu/+source/ufw/+bug/1726856 I "ufw enable" then several seconds later networking stops.

Right after reboot I tried to get the status. Result is . . . . root@loki:~# s ufw status ERROR: problem running iptables: Another app is currently holding the xtables lock. Perhaps you want to use the -w option? . . . . while fail2ban is setting up its rules. Anyway... After a reeboot, whatever I've done seems to have worked.

[Touch-packages] [Bug 1956029] [NEW] ufw does not activate at boot time
Public bug reported: I was advised to start a bug report: https://bugs.launchpad.net/ubuntu/+source/ufw/+bug/1726856/comments/38 I "ufw enable" then several seconds later networking stops. I have get Ubuntu to gracefully power-down using the power-button and then gracefully power-up. Out of curiosity, is anyone here having this problem wish ufw starting up at boot time while also using having fail2ban installed? Here is my theory. It takes a while for fail2ban to issue all the iptable commands to configure the firewall. When ufw tries to initialise there may be a clash or lock held either by an iptables instance spawned by fail2ban or an iptables instance spawned by ufw. One of them will fail and will quite probably mess-up ufw's rules breaking network connectivity. This time I waited for fail2ban to finish establishing its iptables rules before issuing "ufw enable" and this time round network connectivity was not lost.
