using own ntp server

2009-10-11 Thread kenneth hatteland
If I have understand ntp right it is possible to hook up my machines to 
the machine running the ntp server. nevertheless I am not able to find 
anywhere helping me with configuring these machines to connect to my 
server and I am still not bright enough to figure out the syntax myself. 
Does anyone know about a web page or anything that my Googling have 
missed ? Or perhaps  I have gailed to grasp nto correct, and all 
machines must be configured like the handbook says to connect to 
external machines ?


Blessed Be

Leaving aside two areas which could cover a multitude of complications 
should you pursue them, namely


1)  You start setting various security settings and make your ntp server 
effectively unreachable, or


2)  the ability of your local server to multicast time data,

your local ntp server should look like any other ntp server to which you 
have access (other than for less latency and jitter should your network 
be normal).


Put

server IP_OR_FQDN_OF_LOCAL_NTP_SERVER_HERE

in the ntp.conf of your client machines and see what happens.  The 
peers query from the ntpq program should let you know if you have 
success or have somehow locked yourself out / blocked access.


Feel free to give us specifics of what you're doing if this doesn't work.

BTW, the above assumes that you mean setting up your various local 
machines to all use ntpd, but not all query outside machines.  If this 
isn't it, you're going to have to tell us what you mean by hook up my 
machines to the machine running the ntp server.

Take a look at OpenNTPD from OpenBSD. There are only two, three
configuration options. :)

For server:
listen on *
servers pool.ntp.org

For clients:
server 10.0.0.1

Everything should be made as simple as possible, but not simpler.
