ntp

Network Time Protocol daemon and utility programs

NTP, the Network Time Protocol, is used to keep computer clocks accurate by synchronizing them over the Internet or a local network, or by following an accurate hardware receiver that interprets GPS, DCF-77, NIST or similar time signals. This package contains the NTP daemon and utility programs. An NTP daemon needs to be running on each host that is to have its clock accuracy controlled by NTP. The same NTP daemon is also used to provide NTP service to other hosts. For more information about the NTP protocol and NTP server configuration and operation, install the package "ntp-doc".

openntpd

OpenBSD NTP daemon

NTP, the Network Time Protocol, is used to keep the computer clocks synchronized. It provides the ability to sync the local clock to remote NTP servers and can act as NTP server itself, redistributing the local clock. This is an alternative implementation of the NTP software, made by the OpenBSD Project. It makes use of privilege separation, only implements a subset of the NTP protocol, adjusting the rate of the clock to synchronize the local clock. Alternative packages which provide similar functionality are ntp and chrony.

ntpsec

Network Time Protocol daemon and utility programs

NTP, the Network Time Protocol, is used to keep computer clocks accurate by synchronizing them over the Internet or a local network, or by following an accurate hardware receiver that interprets GPS, DCF-77, or similar time signals. This package contains the NTP daemon and utility programs. An NTP daemon needs to be running on each host that is to have its clock accuracy controlled by NTP. The same NTP daemon is also used to provide NTP service to other hosts. This is the NTPsec version of NTP. NTPsec is a secure, hardened, and improved implementation derived from the original NTP project. For more information about the NTP protocol and NTP server configuration and operation, install the package "ntpsec-doc".
