first, related loopback address basic concept What does the loopback address of a device on a router mean? The local loopback interface (or address), also known as the loopback address (loopback addresses). This type of interface is the most widely used virtual interface,

Linux loopback NIC Driver Design, linux loopback NIC Driver Loop NIC Driver1. The difference between a back-to-loop network card and a common network card is that it is virtual rather than a physical network card. It is equivalent to concatenating the sending end and the receiving end of the common network card.2. in the kernel source code, the loopback Nic Progr

Enable the loopback access permission for the UWP application, and enable the loopback permission for the uwp Application Recently, I encountered a requirement for UWP to call WCF in the project. Considering that UWP cannot host the WCF Service (if possible or with similar technologies, please let us know), I wrote a WPF program to host the WCF Service, then use UWP to call the service. I didn't encounter a

During the installation of 11g, this machine encountered the need to install the loop adapter. My system is Windows 2003 Server. in the network environment of the lab, IP addresses are automatically allocated by DHCP. If Oracle finds that your machine is using DHCP, install the Microsoft loopback adapter to provide a static IP address. For details about the installation method, see: 1. Click start, and then click Control Panel ".2. If you are in t

How to use Fabric to automate your tasks and fabric automation tasks First, let's look at an example. We know that under * NIX,unameCommand is to view the release of the system. You can write such a Fabric script: from fabric.api import rundef host_type(): run('uname -s') Save the preceding script as fabfile. py.fabThe command executes the host_type script on mul

What does fabric mean by fabric? Fabric is a powerful batch remote management and deployment tool in Python. It is often used to execute SSH tasks in batches on multiple remote PCs. The common usage methods are summarized as follows: 1. First, write the tasks executed in batches to a fabfile. py file, #-*-Coding: UTF-8-*-from

Loopback is actually a hole. But if it's not a hole, it can do something, like Cisco's NVi. Since the prophase is "if it is not a hole," then you need to make some changes to the code. Before you change, you have to understand why the Linux loopback interface is a hole. The standard stipulates that all packets attempting to go through the loopback interface to a

Two fabric Parallel Methods: fabric parallel Fabric is a python class library. The command line tool based on the ssh protocol is used for Application Deployment and system task management. The following describes two ways to run fabric code in parallel: 1: Parameter-P from fabric.api import * host1 = 'root@ip1:22'

Fabric application case and fabric application case Example 1: file packaging, upload, and validationWe often do some file package distribution work. The implementation step is to compress and package the files first, upload them to the target server in batches, and finally perform Consistency Verification. In this case, put () methods to upload files. By comparing the md5 values of local and remote host fi

1. To identify and manage network devices (such as routers and PCs), we usually use interfaces of these devices (including physical interfaces and logical interfaces: for example, vlan. However, although the device is not out of the network, the device cannot be managed because the interface status of the management address is down (because the physical connection is disconnected, the API Protocol cannot start ). To solve this problem, the loopback in
