NTP Service
Equatorial sundial of 1780, made in the city of Friedberg, Bavaria, Germany.
Now in the
local museum. The pole bar on the hour ring is turned down in the winter
and up in the summer. The hour ring is turned up to the local elevation
on the pole height quadrant (left), according to a table listing towns
in Europe. The whole dial is turned horizontally to the right azimuth
using the built-in compass.
Duration
Our network time service and this accompanying
web site are now (2008) up and running for 10 years.
The
old servers are still
going strong, the network and thus the quality of service
are better than ever. We hope the next 10 years will hold
for us even more improvements and no problems.
Service
Simple time servers are offered in the campus network of
Augsburg University of Applied Sciences.
(How would you call 'Fachhochschule' in English?)
They are accessible from the Internet on request.
Please look at the page
Usage
for details.
The Network Time Protocol NTP version 3 and 4 and the
Simple Network Time Protocol SNTP are supported
in server mode. Peering with other stratum-2
(buddy) servers is possible on request.
There is a campus broadcast service,
but no multicast service.
Alternative
As an external user, please consider using a geographically close
NTP Pool Time Server since that will be sufficient
in many cases and is easier for you.
pool.ntp.org
is a project to provide a 'public ntp time server for everyone'.
It's idea is load balancing over the most used time servers. Our
servers are pooled too, so you will use them anyway.
Access
Access policy:
internal free
(authentication key needed for broadcast client)
external PPR
(prior permission required by
email)
Availability:
not guaranteed
The servers are sometimes off-line for
maintenance and upgrade.
Hierarchy level:
stratum 2
Forced to this level because we have
only low precision radio clock receivers.
Network addresses and NTP versions:
tick.fh-augsburg.de (141.82.49.100) v.3
tock.fh-augsburg.de (141.82.49.101) v.3

Performance
You may yourself assess the performance of our
NTP servers. Look at the actual status of
server references and of radio clocks.

clock loop and the external server connections.
