ntp-4.1.1b: description + notes

The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem. It provides accuracies typically within a millisecond on LANs and up to a few tens of milliseconds on WANs relative to Coordinated Universal Time (UTC) via a Global Positioning Service (GPS) receiver, for example. Typical NTP configurations utilize multiple redundant servers and diverse network paths in order to achieve high accuracy and reliability. Some configurations include cryptographic authentication to prevent accidental or malicious protocol attacks and some provide automatic server discovery using IP multicast.

When installing this package, you should modify your system in the following ways:

  1. chkconfig ntp off # IRIX 6.5.21 and later systems only
  2. chkconfig timed off
  3. chkconfig timeslave off
  4. chkconfig fw_ntp on

When NTP is started, it will automatically find other NTP servers on your subnet via the broadcast mechanism. If you want to point at a specific NTP server, you need to edit /etc/init.d/fw_ntp.
