1. "The NTP socket is on use, exiting" error appears. The reason for this is that the system NTPD server is running and can be via PS aux | grep ntpd View, if you still want to manually synchronize time, you must first stop the service, the command is:service ntpd stop or/etc/init.d/ntpd stop2. Npdate time.windows.com or ntpdate us.pool.ntp.org will be able to synchronize

proposed in 1985 by Professor David L. Mills of the University of the United States, in addition to estimating the round-trip latency of packets on the network, and independently estimating the computer clock bias, To achieve high precision computing on the network, it is a communication protocol designed to enable different machines to maintain the same time on the Internet.

When a program runs on multiple servers, the clock on these servers is sometimes the same. However, when the server runs for a certain period of time, the clock on each server may be different, in this case, all servers need to automatically calibrate their respective clocks. NTP is a convenient

I. Introduction Network Time Protocol (NTP) is used to synchronize time between the distributed time server and the client. NTP is transmitted Based on UTP packets. The UDP port used is 123. NTP is used to synchronize the

Many of us have already used Cisco routers quite well. However, in the face of the NTP time synchronization server configuration, we may not all know about it. Here we will introduce it to you. For the purpose of network management, we set up netflow to monitor traffic and obtain detailed access records for Intranet users to access the Internet. Such records can be accurate to seconds, the premise is that t
