BitMover's ntp.bkbits.net service is no longer operational and we are
pleased to announce our replacement service at bk.ntp.org.
The NTP BitKeeper Repositories are now located at bk.ntp.org; please
configure your BitKeeper client to use this new host-name.

I cannot speak for the OP, but it would seem that any two NTP servers

I did a very cursory check to see if this was already brought-up but
may have missed it. Folks interested in addressing highly variable
delays in networks and such may find the "codel" AQM interesting. It
seeks to keep the time packets spend in queues down as part of
addressing "buffer bloat."

thanks for reply.
Yes, this is my problem that address is allocated for ipv4 address, so
i can't see my complete ipv6 address, and i am not able to know that
what is complete ipv6 address of server i am synced with ( like in
this case, i am synced with server 2001:5b0:3eff:fffa::310 while i see

Hi Dave T, and others,
(I'm cross posting my reply to the NTP questions list since I think they'd be
interested too. The original message was from the Thumbgps-devel mailing list.)
I enjoyed that article. I'll admit to not spending 4 hours studying it, and
sometimes my eyes glazed over, but I e

software uses the output of the ntpd -c "rv assid" 127.0.0.1 to determine if
the NTP server is reachable and if it is synced or not by inspecting the

Hi,
I am running my ntpd in ipv6 multicast mode, below is my conf file :-

I am syncing with ntp server whose ip is :- 2001:5b0:3eff:fffa::310
