NTP time conversion, Baidu has long been no results. I have tried it for myself.
The time the packet is sent on the device is NTP format, and the raw data in the Wireshark is:

1, through the struct.unpack, into the integral type:
S4=struct.unpack (' 4 B ', buf[0][102:106])
The results are as follows: 218 229 208 229
2. Each integer is converted to a 16 string, and the result is as follows:

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.

Network Time Protocol (NTP, Network Time Protocol) is used to synchronize all of its client clock services. The NTP server synchronizes the clock of the local system with a public NTP server and then serves as a time host so that all clients on the local network can synchronize the clock.
The biggest benefit of clock synchronization is the data in the log files o
Configuring NTP to set up the local time server NTP is a protocol used to keep the system and a precise time source at time. in Linux, we can use the Network Time Protocol to keep our system accurate. install: # Yum install NTP or find the ntp rpm package from the installation disk. when you only have one server that c
NTP server is used for LAN time synchronization. You can ensure that all servers in the LAN are synchronized with the time server. Some applications require a higher time-to-live nature. Requirements must be unified time, so the configuration of the time server is important.The internet has a lot of time servers. For example, there is a free NTP server with Fudan University: Ntpdate ntp.fudan.edu.cn. Nanjin
