Unix - Linux Time synchronisation
Accurate Time for UNIX and LINUX
Time synchronisation is necessary to provide accurate time across a network. The provision of an accurate time ensures that services and
operations proceed in an orderly fashion.
NTP and UNIX\Linux
Network Time Protocol is the standard service for time dissemination across TCP/IP networks. It provides accuracies of 1-50ms, depending
on the characteristics of the synchronization source and network paths.
Most UNIX and Linux operating systems provide built-in time synchronisation functionality with its NTP (Network Time Protocol) daemon.
If the NTP service is not available on your version of UNIX\Linux, open source can easily be downloaded and re-complied from www.ucl
The NTP service for UNIX and Linux can easily be configured to obtain accurate time from any of Galleon NTP time servers:
An NTP time server can provide synchronisation for any number of UNIX\Linux machines and many other devices across an IP network.
Using the UNIX\Linux NTP service 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
NTP Fault Tolerance
Configuring an UNIC\Linux NTP service with multiple NTP time sources can provide fault tolerance. If a time server fails, time can be
obtained from other time servers in the list.
