The establishment of the Linux wap Gateway enables us to use our own servers to provide wireless Internet browsing. It is worth a Linux enthusiast's own test at home, let's take a look at the differences between our own Linux wap Gateway and China Mobile's wap Internet access and enjoy DIY. I. System Requirements Libxml2 library 2.2.5 or later is required. This XML library is required to install and compile

This essay goes on to learn a more important Component API Gateway service in MicroServices. When we finally have to provide external access to the micro-service architecture, we need a unified access portal, to hide our internal service URL details, which is a bit like the concept of the gateway in the LAN, this is the API Gateway Service has emerged. API

Citrix NetScaler Gateway, the basics! September, 2014 by Bas van Kaam I don ' t want to spend to more than talking about the different kinds of editions and or licenses available, if you are want to Know about those I suggest you check out one of my previous articles here, or just give citrix.com a visit. Throughout this article I ' d like to briefly focus on some of the basic terminology and traffic flow that comes with the Ne Tscaler

wrong judgment and think that the destination machine is in the same subnet, then the packet will be in the network loop, until the timeout and So that the data does not reach the destination machine correctly, causing the network transmission error, if the subnet mask is set too small, then the communication between the machines belonging to the same subnet as cross-subnet transmission, the packet is given to the default gateway processing, which wi

Shared guard version 2.0 has added many features. The most important one is that it can provide automatic host switch. In order to ensure the implementation of the host switching function, the configuration is much more complicated than Version 1.0, especially when users use the fixed IP Mode of a single Nic, the concept of the virtual network card and the virtual gateway is not very clear, resulting in configuration errors and cannot access the Inter

Recently, some friends have reported that they are not familiar with the configuration of wireless gateways, so I will explain in detail some questions about wireless gateways, including the selection of wireless gateways, wireless gateway settings and explanations of some related terms. In a broad sense, a "Gateway" refers to the "interface" connecting a network to another network. For example, if an enter

Gateways (Gateway) are also known as inter-network connectors, protocol converters. The gateway realizes network interconnection above the network layer, is the most complex network interconnection device, only for two high-level protocol different network interconnection. Gateways can be used for both WAN interconnection and LAN interconnection. A gateway is a c

The simplest understanding is that the respective IP addresses of the two computers and the subnet mask after the and operation, the result is the same, the two computers are on the same sub-network, you can make direct communicationGateway:So

New technologies are emerging again in routing technology. At present, a new generation of intelligent routing technology has been released worldwide, and the new smart routing technology is used to add stealth capabilities to gateway devices. Wedge Networks, a global leader in network security and Web security, announced the release of the latest smart routing technology worldwide. At the same time, this new technology will be integrated into the BeS

LindDotNetCore ~ Ocelot implements the microservice gateway, Back to directory The Gateway has its own definition in the hardware, and the software architecture also has its own explanation. It is the entrance to all requests, and requests are routed to the gateway for processing and processing, return to the client. In this process, the core of the

Contact with the switch has been for some time also, you can find that some of the content seems more confused, such as: Switch configuration default gateway, configuration of the specific command has been very familiar, but now is not quite understand why to complete the switch gateway settings, I also find some information on the Internet, and some say to remote access to the switch, Some say the communic

Gateway, we all know, from one room to another room, must go through a door. Similarly, sending a message from one network to another must pass through a "gateway", which is gateways. The gateway, as its name suggests, is a "gateway" to a network connected to another network. According to different classification crite

The contact with the vswitch has been around for a while, and you may find that some content is getting confused. For example, if the vswitch configures the default gateway, the specific configuration commands are quite familiar, but now I don't quite understand why I want to complete the switch gateway settings. I also found some information on the Internet, some for remote access to the switch, and some f

This is a creation in Article, where the information may have evolved or changed. Background As we all know, Docker has made a profound change in the IT world these years,From development to testing to operations, there is a shadow of it everywhere.It also facilitates the micro-service architecture and moves forward. In the latest version of Docker (CE 17.03), with swarm mode the maturity,In a simpler scenario, you can no longer need a special 基础设施管理服务编排, 服务发现 , 健康检查 , and 负载均衡 so on. But API

Through the previous sharing, we learned about several core facilities of the microservices architecture, through which we can build a simple microservices architecture system. For example, through spring Cloud Eureka to build a highly available service registry and realize the registration and discovery of services;Load balance through the Spring cloud ribbon or feign, and fault-tolerant protection with spring cloud Hystrix to avoid a failure spread. After the microservices are set up, we will

Spring Cloud (11): Service Gateway Zuul (filter) "Version Finchley" Posted in 2018-04-23 | updated on 2018-05-07 | In the previous article we learned about the basic functionality of Spring Cloud Zuul as a gateway: Routing (Router). In this article, we will focus on another core feature of Spring Cloud Zuul: Filter.The role of FilterWe have been able to implement the routing capabilities of the request

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. I checked a lot of information and finally was able to build a WAP gateway on Linux! After the establishment, you can use your own WAP

504 Gateway time-out issues common to Web sites that use Nginx as a Web serverI met this problem when I was upgrading the Discuz forum.In general, this situation may be due to the Nginx default fastcgi process response buffer is too small, which will cause the fastcgi process to be suspended, if your fastcgi service is not good for this suspend processing, then it is very likely to cause 504 Gateway Time-ou
