I have build a test package for the community to validate it solve the bug before starting the SRU process [1]. The goal of this testfix is only to confirm that this solve the bug and it is not a final solution.
Here's what has been brought to my attention about the test package I have provided. --- I confirm that the proposed testfix package resolved the issue. The test were made on test machines where the client had an iptable postrouting nat forcing the source port to be under 123. - ntpdate command performed on the client machine was successful - tcpdump on the server side confirmed that the source port was under 123. Please advise for the next steps Thank-you --- [1] - https://launchpad.net/~slashd/+archive/ubuntu/bug1479652 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/1479652 Title: [patch] ntpd rejects source UDP ports less than 123 as bogus Status in NTP: Fix Released Status in ntp package in Ubuntu: In Progress Status in ntp source package in Precise: In Progress Status in ntp source package in Trusty: In Progress Status in ntp source package in Wily: In Progress Status in ntp source package in Xenial: In Progress Status in ntp package in Debian: New Bug description: [Title copied from Debian bug, which was not filed by me. Description below is mine.] If an NTP client sends a request with a source port less than 123, the packet is silently ignored by ntpd. This is occurring in our environment due to NAT. Attached is the patch already accepted upstream which fixes the issue. I've verified it fixes the problem. Debian has been ignoring this patch for almost 3 years. Can we get this in Ubuntu please?
