ntp time servers

Configure NTP time synchronization on Linux with a break operation step, sorted as follows: 1. Install packages (on server and client): The code is as follows Copy Code Yum Install NTP 2. Server-side configurationFor example:First, the server IP address is set to: 192.168.146.110 Modifying the

Network Time Protocol (NTP) is a network protocol used for Packet Exchange to synchronize the clock of two computers. NTP uses UDP port 123 as the transport layer. It is used to offset the impact of variable latency. NTP is one of the oldest network protocols in use (started before January 1, 1985 ).

the command line; Export TZ can be. When the date view time, the system is to find the TZ environment variable, TZ is not set to take the search for/etc/localtime file, so the TZ environment variable settings will overwrite the /etc/localtime file information, but the environment variable settings at the next logon is not valid, To be permanently valid, you can write commands to the/etc/profile file. Time

Current network of the host, the business side sent to have an unsynchronized. Before also encountered similar problems, generally are NTP dead, resulting in the time is not synchronized.

Streaming Server to see how people did it, grabbed the package, found several RTCP points, and drew a number axis, the packet capture tool Wireshark will display the NTP time (for example,), so I used to calculate it, and finally calculated that the unit is about 232 picoseconds. I substituted this value into my source code, sure enough. Although the problem has been solved, there has been a knot in my

Cause: After you restart the NTP service on the NTP server, it

This article describes in detail how to configure the NTP time synchronization server, and takes CISCO 7200 as an example. I hope this article will help 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 the

The hardware clock is local time, the kernel clock is UTC time, no time zone is set, and there is no option for any time zone setting. Second, demand
