Sometimes we need to ping some addresses on Linux to determine if the address is occupiedFirst, write the shell scriptThe script is as follows:#!/bin/bashfor i in 192.168.16.{1..255} do (ping $i-C 2 >/dev/null 2>1 [$?-eq 0] echo "$i is Alive" ) doneThe effect is as followsSecond, the use of fpingFping needs to be installed separately, it can ping a group of addresses,-G to specify a set of addresses, such asFping-g 192.168.16.1 192.168.16.200Represents all the addresses between these two addres

What if devices are scattered? Try link layer Discovery Protocol In a large network, it is very important to know what is connected to the network. The larger the network, the more logical and physical it is-the harder it is to clarify its topology. In addition, redundant links and link aggregation will greatly increase the difficulty of clarifying the interconnection between devices in the network. In addition, the problem persists. Hybrid use of ne

kepler-452bKepler-452 and the Earth's contrast chart, the kepler-452b volume is 1.6 times times the earth.Latest: NASA: The Kepler Space Telescope confirmed the discovery of the first "habitable" planet with a similar size to the Earth, called Kepler 452b, the Earth 2.0, 1400 light-years from Earth, orbiting a star very similar to the sun. Kepler's next mission will begin in 2017: finding habitable planets around our nearby stars.EARLIER: NASA said it

Welcome to the ". Net Discovery series"ArticleIn this article, I will explain the. NET JIT knowledge in two parts. JIT (just in time) is. net is a mechanism for compiling while running. This mechanism is named by a production method implemented by Toyota in 1960s ". . Net jit compiler, in terms of its original design intention and running method, is very similar to the "punctual production" system of Toyota Motor, so let's first understand it t

Discovery and consumption of servicesWith service centers and service providers, let's implement a service consumer:Service consumers mainly complete two tasks-service discovery and service consumption, Service discovery task is done by the Eureka client , and the task of service consumption is done by the Ribbon .The Ribbon is a load balancer based on HTTP and T

ETCD is a highly available key-value storage system that is used primarily for shared configuration and service discovery. ETCD is developed and maintained by CoreOS and is inspired by ZooKeeper and Doozer, which is written in the go language and handles log replication through the raft consistency algorithm to ensure strong consistency. Raft is a new consistency algorithm from Stanford, suitable for the log replication of distributed systems, raft to

Everything starts from here. The prism document is a bit harsh on the two concepts, or even self-defeating. I 'd better not read them. We know that in each module, the module class that implements the imodule interface must implement the initialize method of this interface. On the one hand, we must register some custom interfaces and classes that implement this interface, prepare for the subsequent dependency injection. On the other hand, load the view for Region and display it (initialize the v

Recently in the thinking of a problem, the online server run a variety of services, it may be running Nginx, another run is MySQL, the other is to run NFS or other services, etc. Through a certain script fixed write some services to implement monitoring all the server's process resource consumption Zabbix server resources do not say, if the server ran the service is not on the fixed list, the monitoring service can not get the corresponding data.In order to solve this problem, recently in the Za

Service discovery is one of the key principles of micro-service architecture. Trying to configure each client or some form of convention can be very difficult and very fragile. Consul provides service discovery services through HTTP APIs and DNS. Spring Cloud Consul uses the HTTP API for service registration and discovery. This does not prevent non-spring cloud a

This service is now used to be very small, and it is recommended that you use it manually, so that we can use it when we need to use it, If your computer discovers that this service corresponds to the Svchost.exe process using the CPU very much, can turn it off, but it is not recommended to permanently disable it to start, let's learn more about SSDP Discovery service. 1 The process that corresponds to the SSDP
