Hi all. I posted a question on this last December, but I never received feedback on it. Here is the bug report https://bugs.launchpad.net/ufw/+bug/1652163.
-- 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/1204579 Title: ufw doesn't support concurrent updates Status in ufw: Triaged Status in ufw package in Ubuntu: Triaged Status in ufw package in Debian: New Bug description: On a server under Ubuntu 12.04 I automatically update firewall rules and I unfortunately noticed that if 2 rules are processed at the same time it leads to an inconsistent result between iptables and ufw status. In fact it can be reproduced using the python script in attachment. Before executing this script I didn't have any rules matching the ip 192.168.254.1 on my computer. After a launch iptables takes into acount 464 rules. sudo iptables -L -n | grep 192.168.254.1 | wc -l 464 It should be 500 rules but the script stressed a lot my system and all rules can't be processed by iptables sudo ./test_ufw_threads.py iptables: Resource temporarily unavailable. iptables: Resource temporarily unavailable. iptables: Resource temporarily unavailable. [...] Anyway, ufw stores only the last updates (in /lib/ufw/user.rules): sudo ufw status État : actif Vers Action Depuis ---- ------ ------ 192.168.254.1 1234/tcp ALLOW 192.168.46.9 192.168.254.1 1234/tcp ALLOW 192.168.22.10 192.168.254.1 1234/tcp ALLOW 192.168.32.10 192.168.254.1 1234/tcp ALLOW 192.168.5.10 192.168.254.1 1234/tcp ALLOW 192.168.43.9 192.168.254.1 1234/tcp ALLOW 192.168.40.10 192.168.254.1 1234/tcp ALLOW 192.168.46.10 192.168.254.1 1234/tcp ALLOW 192.168.48.10 192.168.254.1 1234/tcp ALLOW 192.168.42.10 192.168.254.1 1234/tcp ALLOW 192.168.43.10 So I can't delete other rules using ufw, I had to directly use iptables. In this case I can only delete 10 rules using ufw. Could you please handle some kind of lock?
