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 the time of the monitored vro or vswitch and o

The NTP clock synchronization configuration on AIX6.1 describes the ntp synchronization server time. Currently, the NTP service is not widely used. Recently, a project, DB2 cluster, has some requirements on time consistency, so I thought about ntp, although timed can also be used, it is only valid for broadcast domains

The/etc/linux ntp.conf system-config-date network Time Protocol (Linux NTP, web-hour protocol) is used to synchronize all of its client clock services. The Linux NTP server synchronizes the clock of the local system with a common Linux NTP server and then serves as a time host so that all clients on the local network can synchronize clocks.The biggest advantage o

Recently, we have the opportunity to transplant a GPS device to our product. It is very easy for the GPS module to transplant itself. A friend who has developed GPS for wince or PC must be clear about it. He just reads the standard GPS data from the serial port, parses the data, and the application obtains the longitud

The server is very time-critical, the generation of Linux server files, logs, and database connections are based on the logic of timeTask processing, if the time is not synchronized, then, the processing of the task, and the analysis of the problem log, the time is wrong, difficult to analyzeDirectly change the Linux server time, the impact is particularly large, we all know that the server farm startup is regular, if you arbitrarily change the Linux server timeis likely to cause time logic stat

Its purpose is to synchronize the computer clock to the World coordinated UTC, its accuracy in the LAN up to 0.1ms, in most places on the Internet its accuracy can reach 1-50ms. NTP the
