1) don't bother. Linux PPS will log the time of both the GPS's PPS
and the Rb PPS. Read the log file to determine the offset. This give
offset with uSec precision. To get better you need a hardware ti

Try:

That would configure a symmetric mode association. You could go that
way, but I'd stay in the more familiar client/server territory if I
were you.

Lots of good discussion here but I found an easy way to stay "on-time"
while the Internet is down and GPS is not available. There are some
people on eBay selling Rubinium oscillators for about $40. They have
a pulse per second output.These Rb clocks will keep NTP within
reasonable specs for a

thanks for your answers.
I am using Ubuntu operating system and the IP addresses are assigned
manually and they are fixed. I also disabled the firewalls of both systems.
I changed the Files as follows:
#ntp.conf
#ip: 192.168.17.11
driftfile /etc/ntp.drift
tos cohort 1 orphan 11

If he's offline to the ubuntu server, won't that, effectively, make both
server lines redundant, or does orphan require a token server.
One problem I see is

OffLine,
Hi Ali,
If you're running Windows, you have to go into the firewall control
panel on the server machine and allow an exception for ntpd to receive
data queries through the firewall. There may be similar procedures you
have to do on Linux.
See the lines below to insert into ntp.conf for secu
Hi,
I have a couple of offline systems and they are all in the same network. I
want to chose one of them as time server and the others sync their time
with that machine.
This is the configuration file for the server:
#ip: 192.168.17.11
server ntp.ubuntu.com
driftfile /etc/ntp.drift
and this conf
19 matches
