Public bug reported: [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? ** Affects: ntp Importance: Unknown Status: Unknown ** Affects: ntp (Ubuntu) Importance: Undecided Status: New ** Affects: ntp (Debian) Importance: Unknown Status: Unknown ** Patch added: "Patch from upstream, made suitable for debian/patches" https://bugs.launchpad.net/bugs/1479652/+attachment/4436105/+files/udp-ports-under-123.patch ** Bug watch added: bugs.ntp.org/ #2174 http://bugs.ntp.org/show_bug.cgi?id=2174 ** Also affects: ntp via http://bugs.ntp.org/show_bug.cgi?id=2174 Importance: Unknown Status: Unknown ** Bug watch added: Debian Bug tracker #691412 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=691412 ** Also affects: ntp (Debian) via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=691412 Importance: Unknown Status: Unknown ** Description changed: [Title copied from Debian bug, which was not filed by me.
