Hi all,
I'm sure this question was asked before but I couldn't find what I was looking for in the 2 threads I found on here.
Here's my question/problem:

All,
I have a Windows XP client which I need to get time synchronized from a Linux ntp server. What are the commands to perform the setup and configuration?
Thanks,

All,
How do you set a Solaris 9 server which received ntp updates from a ntp server to broadcast them on a local subnet. I have created a /etc/inet/ntp.conf file to receive the updates from a server on network and need to make this server become like a ntp relay from the main server.

Hi,
I'm trying to configure NTP client, however it failes to sync correctly.
Even after I manually set the time, once it connects with the NTP server, it pushes the time ahead by 4 hours.
We have set an AIX host as NTP server. It works fine for other AIX hosts, however fails on RHEL 5.4

Hi,
I have two ntp servers in my cluster and I want all the nodes in my cluster to sync with either of the ntp servers or just one. Unfortunately it keep rotating the sync, between my ntp server 1, ntp server 2 and local. Is there anyway I can change the sync to avoid local?

ntp.conf
ntp.conf(5) File Formats Manual ntp.conf(5)Name
ntp.conf - Network Time Protocol configuration file
Description
The file is the configuration file for the Network Time Protocol (NTP) daemon, This file must be configured on your system before running
Any host names that you specify in the file must have an entry in the file, or an entry in the master database, if the database is being
served to your system by BIND/Hesiod or Yellow Pages.
The file has four entry formats:
trusting no
This entry guarantees that your system synchronizes only to the NTP servers identified in the peer and server entries specified. Dig-
ital recommends that all systems include the entry.
peer server
This entry identifies server as one of the NTP servers that your system trusts, and from which your system will accept time synchro-
nization. Your system may also provide time synchronization to this server. Servers can be identified by host name or internet
address.
NTP servers should be configured with entries.
server server
This entry identifies server as one of the NTP servers that your system trusts, and from which your system will accept time synchro-
nization. Your system can not provide time synchronization to this server. Servers can be identified by host name or internet
address.
NTP clients should be configured with entries.
peer /dev/null LOCL 1 -5 local
This entry identifies your system as a local reference clock. A local reference clock is the most accurate system clock available at
your site. If you receive time synchronization from the Internet NTP service, you should not include this entry on any of your sys-
tems. At most, one system in a set of nodes running should be identified as a local reference clock.
A host which specifies this entry should not specify any or entries.
Examples
This is a sample configuration file for an NTP client which receives time synchronization from the NTP servers: and Lines beginning with a
number sign (#) are comments.

# If you are configuring a server, use "peer" entries to
