The 1,ipsec VPN application is more and more extensive, the following configuration instance is to the single headquarters multiple branch organization actual application According to the configuration of this article, we can achieve the maximum VPN connectivity through the minimum number of VPN tunnels, the network topology is as follows: As shown above, the Headquarters firewall machine hub firewall name is fortigate_1, its external network port

The hub works on the first layer of the OSI model, the "physical layer". A hub is a hardware-only network underlying device that itself does not recognize the destination address, so it does not target the data when it sends it, but sends it by means of a broadcast. This means that when it sends data to a node in the network, it sends the data to all nodes connected to the

In the process of learning Docker, the download image speed is particularly slow, because the Docker hub does not deploy a server or CDN in the country, coupled with the speed of the domestic network and other reasons, the image download is very time-consuming. To overcome the cross-ocean network latency, one of the most effective ways to quickly and efficiently download Docker images is to use a domestic Docker image source. Here's how to use the 163

The Docker hub works with Docker and its components. The Docker hub will help you collaborate with your colleagues and get the most functional docker. To do this, the services it provides are: Docker Mirror Host User authentication Automatic mirroring of Build and workflow tools, such as build triggers and web hooks Integration of GitHub and BitBucket In order to use the Docker

found that folder on my butt, right-click and waited for it to be thrown into the dumpster, but! The system also told me that there is no administrator rights, oh My computer I do not have administrative rights ... I am also drunk, and then I Baidu has an administrator authorized registry, finally have permission, so I decisively kicked it to the garbage box. As for the blue screen, OK, blue screens and that folder is not closed, because the cause of the blue screen I do not know why, so just s

Repeater, Hub, switch, and router are all devices generated for different layers of the OSI Layer-7 network model. One by one, they are summarized as follows: Repeater: Repeater Is a connection device of the network physical layer, which works on the OSI physical layer. In fact, it is a signal amplifier. It is only responsible for transmitting signals from one cable to another. It can only be connected to the same type of CIDR Block and cannot be co

The company's more and more computers, cable connection is not enough to change the wireless router, the old router idle. But in the wireless router can not cover the place or to use network cable, so think of using a hub (hub), with an old router, can not use it? Do it, really changed, an old router with a network cable from the company to increase the use of several computers, very cost-effective, especia

For the same Dockerfile,docker hub to build at different times there will be different results, as in the following building Tomcat Image: # based on CENTOS6 base mirroring from Centos:6 maintainer Chenyufeng " Yufengcode@gmail.com " # Set the current tool directory # This command does not add a mirrored layer Workdir/home # Install the necessary tools RUN Yum install-y wget \ rpm--rebuilddb \ NBSP;NBSP;NBSP;NB Sp;yum install-y tar \ wget--no-chec

After using the hub on ce, pay attention to the following points for the USB driver:1. Make sure that the buffer for transmission is large enough.2. If the USB sleep mode is set, make sure that the sleep mode is enabled during sleep.Modify the buffer:E: \ WINCE600 \ PLATFORM \ SMDK6410 \ src \ drivers \ USB \ hcd \ cloud6410_ohci.c[Cpp]// Amount of memory to use for HCD bufferStatic const DWORD gcTotalAvailablePhysicalMemory = 64*1024; // 64 KStatic c

Notification hub, which is a message broadcast mechanism inside an iOS program that enables communication between objects without referential relationships. Notification Center He is based on the observer pattern, which can only communicate within the program, not across application processes. When the notification hub receives the message, it sends the message to the Subscriber based on the settings, where

Thanks to Riku for reprinting the authorization, refer to the original translation.Original article: Turn Gmail into your personal nerve centerAuthor: Steve Rubel Turn Gmail into your personal neural Hub I feel very lucky to use it when Gmail beta is released. Even though I have been using this account for about three years and have more than 100 emails each day, I still only use 18% of the 2.8g space. In recent weeks, I began to use Gmail's large sp

Switch vs router vs Hub Diff Hub) Switch) Router) Different levels of work OSI Layer 1 Physical Layer Layer 2 of OSI. The link layer switch uses the physical address or MAC address to determine the destination address for data forwarding. Layer 3 of OSI, the network-layer router determines the data forwarding address using the idnumber (IP address) of different networks.

as the core. Star: easy to manage, easy to expand, dedicated network devices are required as the core node of the network, more network cables are required, and high reliability requirements on core settings are required. A dedicated network device, such as a hub or vswitch, is used as the core node. Each host in the LAN is connected to the core node through twisted pair wires, forming a star structure. Although the star network requires more cables

Many enterprises build a VPN to build VoIP to achieve better call quality. However, after the establishment, only the VoIP contacts between the external and the central points can be established, and the communication between the external and external points cannot be established. This is because IPSec VPN is point-to-point communication and does not allow external nodes to communicate with each other. Therefore, star VPN networks cannot communicate with each other. The VPN
