How can the micro-cloud sync disk not be synchronized? You can learn through the following to understand the micro-Cloud synchronization disk can not be synchronized, why can not use the micro-Cloud synchronization disk synchronization function? What's wrong? Reason one, upload a single file limit volume within 1G, more than 1G, there may be unable to sync. Second, the micro-cloud synchronization d
Recently in the study of Linux, reading examples (bird's Linux private dishes P674), using Tarball to install NTP, a bit of a problem, prompt error, using the./configure to detect the program, the following prompt appears: Hint Openssl/evp.h this file or directory is missing. Baidu, found that may be the reason: you try to compile the program using OpenSSL, but need and OpenSSL linked files (libraries and header files) on your Linux platform is mis
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 time of the monitored vro or vswitch and other network devices must be absolut
Article Title: Considerations for NTP service configuration in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In the standard configuration of NTP in Linux, many Synchronization Methods are different. Note the following: If you do not want any other server to acc

Background:When the server is more, the time is accurate or not, the consistency is a problem. So it is necessary to unify the time.Here's how to configure a Linux time server within a LAN.Configuration environment and requirements:1. Assume that the Linux machine with IP 192.168.1.201 is the time server in the 192.168.1.0 network segment.2.192.168.1.201 server can Sisu network, can be synchronized with the more authoritative public network time server.3. Other machines in the same network segme

If the server's time is messed up, it can cause a lot of unexpected problems. Using NTP, you can make the server get the right time to avoid problems. NTP is a network time protocol, meaning "Network Time Protocol", is a TCP/IP protocol to achieve the synchronization protocol. Ubuntu automatically goes to NTP every time it starts. ubuntu . com to do time synchr
