Operating Systems Solaris How to configure NTP in Solaris/Windows/Linux environment...??? Post 302105820 by jumadhiya on Monday 5th of February 2007 02:44:21 AM
Old 02-05-2007
Thanks Tornado. Can you suggest me any freeware NTP Server package for Windows 2000/2003 which is more reliable to use in my production environment. I am using different models of systems running with different OS versions & also running with veritas cluster. Let me give you a brief idea of my setup;

1. Windows 2000/2003 server --- Want to use as NTP Server
2. 2 x Solaris 10 Systems (ppip1n & ppip2n) running with VCS 4.1. These 2 Servers are pointing to SMC Server running on Solaris 9 to take the date & time.
Note : I want SMC server to point the Windows NTP server to sync the date & time. pp1n & pp2n will sync the date & time from SMC server.

Please find the ntp.conf configuration from ppip1n, ppip2n & SMC systems;

ntp.conf of ppip1n
***************
ppip1n) inet > more ntp.conf

Note : 10.100.102.254 ---- Windows System IP (NTP Server)

Can you tell me the configuration is proper on ppip1n, ppip2n & SMC systems...???

What exactly is the stratum value & how it affects your configuration...???

Thanks & Regards,

net::ntp

Net::NTP(3pm)						User Contributed Perl Documentation					     Net::NTP(3pm)

NAME

       Net::NTP - Perl extension for decoding NTP server responses

SYNOPSIS

	 use Net::NTP qw(get_ntp_response);
	 my %response = get_ntp_response();

ABSTRACT

       All this module does is send a packet to an NTP server and then decode the packet received into it's respective parts - as outlined in
       RFC1305 and RFC2030.

DESCRIPTION

       This module exports a single method (get_ntp_response) and returns an associative array based upon RFC1305 and RFC2030.	The response from
       the server is "humanized" to a point that further processing of the information received from the server can be manipulated.  For example:
       timestamps are in epoch, so one could use the localtime function to produce an even more "human" representation of the timestamp.

   EXPORT
       get_ntp_response(<server>, <port>);

       This module exports a single method - get_ntp_response.	It takes the server as the first argument (localhost is the default) and port to
       send/recieve the packets (ntp or 123 bu default).  It returns an associative array of the various parts of the packet as outlined in
       RFC1305.  It "normalizes" or "humanizes" various parts of the packet.  For example: all the timestamps are in epoch, NOT hexidecimal.

SEE ALSO

       perl, IO::Socket, RFC1305, RFC2030
