            Bug ID: 221282
           Summary: net/openntpd "ntpctl -sa" claims "clock synced,
                    stratum 2" weeks after last contact to upstream NTP
                    servers
           Product: Ports & Packages

            Status: New
          Severity: Affects Only Me

Dear maintainer,

the main openntpd server on my network had accidentally been without a
connection to the internet for several weeks and thus unable to connect to =
its
configured remote clock sources. Oddly enough, "ntpctl -sa" would still out=
put
a status of "clock synced, stratum 2". Other machines on the network using =
this
server as their clock source would report a stratum of 3.

I would have expected openntpd to consider its clock as out of sync after s=
ome
timeout and notify downstream hosts accordingly. I'm not sure how this case=
 is
intended to be handled as per the NTP protocol. I have, however, seen the
ntp.org ntpd report a stratum of 16 in this case so clients further downstr=
eam
can detect that there is a problem.=20

I have since reconnected the affected machine and things are back to normal.
Let me know if you'd like me to perform any additional tests. It appears th=
at
this can be easily replicated by disconnecting a single openntpd server and
watching the output of "ntpctl -sa" on that machine.

Cheers,

Rene
