The branch main has been updated by cy: URL: https://cgit.FreeBSD.org/src/commit/?id=381956e267569031883a516e10446c29490ee41d commit 381956e267569031883a516e10446c29490ee41d Author: Cy Schubert <cy@FreeBSD.org> AuthorDate: 2025-01-31 22:25:14 +0000 Commit: Cy Schubert <cy@FreeBSD.org> CommitDate: 2025-02-18 17:11:45 +0000 ntp: ntpd does not connect to NTP server with link local IPv6 address Upstream bug 3943 (https://bugs.ntp.org/show_bug.cgi?id=3943) discusses: Starting with 4.2.8p18 ntp does not synchronize or even connect to the configured NTP server any more. ntp stays in .INIT. state indefinitely and checking the network traffic shows that ntp does not attempt to contact the NTP server. This is regression introduced by the fix for upstream bug 3913. This is a similar bug I reported upstream (ntp bug 3841).
