[gpsd-dev] Fwd: Re: Clarifications needed for the time-service HOWTO

[Beat Bolli]

Hi all,

I got this private mail from Ask Bjørn Hansen of NTP Pool fame where he
implies that the pool DNS servers use some IP-based geolocation
jiggery-pokery that should return geographically close pool server
addresses even if one queries the generic pool domain.

So maybe these sections of the HOWTO can be reverted to use the
top-level pool domain?

Hi Beat,

I’m not on that list but someone pointed out the thread to me.

The “generic pool domain” actually will (usually) give you nearby
servers, so you shouldn’t need to use the more specific names. If it
doesn’t work for you, can you send me the output of

dig +short -t txt _country.pool.ntp.org

and

dig +short -t txt _country.pool.ntp.org @a.ntpns.org

?
