Hi,
I'd like to set up a ntp server and several clients connected to the server
itself. Unluckily I'm unable to find documentation on-line, or better I
cannot understand what I've found. Briefly here there's what I've done:
- on the server:
_ installed ntp
_ configuration file /etc/ntp.conf contains the line
server 127.0.0.1
_ I launch ntp and query it:
ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
localhost 0.0.0.0 0 l - 64 0 0.000 0.000 4000.00
- clients:
_ set the ntp.conf file to point to the server:
server ntpserver
_ launch ntp but I get the message (in the warnings) that there is no service
running at the server
_ try with ntpdate but I cannot get the time from the server.
What's wrong with this small configuration?
Thanks,
Luca

Here is a very good resource for NTP configuration along with many other
helpful Linux configurations.

... ciao:
first, to be a server, you have to be a client of one, OR, have
access to accurate time information; typically via 'radio' if no access
to net based time servers available to you. so, line similar to the
following should appear:
"server time.nist.gov"
"server time-a.timefreq.bldrdoc.gov"
these are the 'servers' i poll for time information. when you use the
'loopback' address, you're asking 'yourself' what time it is.
instead of being a 'time server' per se, remote systems use 'rdate'
in a cron event to keep 'hourly accurate' time.
: ntpq -p
: remote refid st t when poll reach delay offset jitter
: ==============================================================================
: localhost 0.0.0.0 0 l - 64 0 0.000 0.000 4000.00
on this system:
[ root ] ~ # ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
time.nist.gov .ACTS. 1 u 1409 1024 16 86.885 -5.531 3.542
*time-A.timefreq .ACTS. 1 u 318 1024 377 95.454 -5.127 5.316
hope that helps ...

New (and preferred way) is to use pool.ntp.org as servers.
Info's are on the http://pool.ntp.org/ IIRC.
