Time Server to synchronize the time on NOVELL networks. Using time from GPS satellites ensures the Galleon NOVELL Time Server is
accurate to fractions of a second providing accurate time for your computer network.

A NTS 8000 will take the UTC time and update the NOVELL server, which can then be used to distribute the time across the network
using standard NOVELL commands. |

Software supplied with the NTS 8000:
Software for NOVELL (5 and 6) a dedicated NLM to synchronize the time on a NOVELL server
All types of organisations all over the world (America, Europe, Australia, and the Middle East) are already using Galleon Atomic Radio
Clocks; we synchronize time across the globe for organisations as diverse as NASDAQ to Buckingham Palace. Other customers include Daimler
Chrylser, 3M, GlaxoSmithKline , Kellogg's, Sharp and Shell.
Server GPS Clock NOVELL. Provides accurate time in any location world-wide by tracking up to 12 satellites, it supplies this time to a
user display and to the computer via a serial interface (RS232).
The NLM software driver will synchronize the time on a single NOVELL Server. Consists of mains powered GPS Computer Clock with remote
antenna up to 1,000m (3,000 ft) away, serial interface, LED Time signal display and power supply. Guaranteed to obtain a signal.
Time synchronisation is necessary to provide accurate time across the Novell NetWare network. The provision of an accurate time ensures
that directory services operations proceed in an orderly fashion.
NTP and Netware 5 and 6
NetWare provides built-in time synchronisation functionality in its Novell-provided Timesync.NLM. Timesync.NLM in NetWare 4.x could only
use IPX as its communication protocol. In NetWare 5, Timesync.NLM has been enhanced to work over TCP/IP and act as an NTP client.
NetWare 5 and 6 can easily be configured to synchronize to any of Galleon NTP servers:
- NTS 8000 - rack-mount NTP server.
- Time Sync NTP - NTP server for Windows NT/2000/2003/XP.
Key Benefits
Using the Novell-provided Timesync.NLM with an NTP time server has a number of key benefits:
- Reliable and secure source of time.
- Easy to install, configure and maintain.
- Low processing overhead on Netware Server, using built-in functionality.
- Fault tolerance can be acheived by using multiple NTP servers.
- NTP server can be used to synchronise other clients on the network such as Netware servers, routers, Windows clients, UNIX clients and
more.
Configuring a NetWare Server as an NTP Client
To configure a NetWare Server to act as a NTP client, first identify the root time servers in the network. This is either the 'Single
Reference' server or the 'Reference' and 'Primary' servers together.
Update the root servers so that they obtain time from the NTP server time source:
SET TIMESYNC TIME SOURCE=xxx.xxx.xxx.xxx:123
Where xxx.xxx.xxx.xxx specifies the IP address of the NTP server. Port 123 is the UDP port used by NTP.
The entire network looks to the root time sources for time. Therefore, the entire network will be synchronised to the NTP server.
NTP Fault Tolerance
Configuring TimeSync.NLM with multiple NTP server sources can provide fault tolerance. If a server fails, time can be obtained from other
servers in the list. Multiple sources can be specified by separating the IP addresses of each server by a semi-colon:
SET TIMESYNC TIME SOURCE=192.168.0.1:123;192.168.0.2:123;
