Pedro, I fail to see how this is a bug at all. ntpd is a network service, and while it would be a nice enhancement to the packaging to have a low priority debconf question to ask if the user would like to disable network capabilities, there are plenty of users who will want it to listen on the network and respond to time requests.
Also you may be surprised to see that ntpd doesn't actually *respond* to requests from ip's other than 127.0.0.1 or ::1 clint@clint-MacBookPro:~$ ntpq 192.168.1.105 ntpq> peers 192.168.1.105: timed out, nothing received ***Request timed out ntpq> ^D clint@clint-MacBookPro:~$ ntpq 127.0.0.1 ntpq> peers remote refid st t when poll reach delay offset jitter ============================================================================== +host2.kingrst.c 204.9.54.119 2 u 261 1024 377 84.351 -7.327 9.672 -vf1.bbnx.net 128.4.1.1 2 u 223 1024 377 155.919 14.811 9.898 *ntp.yoinks.net 198.153.152.52 2 u 802 1024 377 50.601 -12.461 14.969 +ticker.pascogov 128.4.1.1 2 u 339 1024 377 78.144 -4.778 6.295 +europium.canoni 193.79.237.14 2 u 263 1024 377 165.478 -12.394 8.661 ntpq> So its not actually all that important at all. I'll mark this as Opinion, so others can find it and weigh in on it. For now though, I don't see a compelling argument for changing the way it works right now. ** Changed in: ntp (Ubuntu) Status: New => Opinion ** Changed in: ntp (Ubuntu) Importance: Undecided => Wishlist -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/858493 Title: By default ntpd listens on all interfaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/858493/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
