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?
