Because I am also a beginner, writing these things is also to give themselves a summary of learning, so inevitably there is a wrong place, welcome to correct me.This article is from the "industrious Little ant" blog, plea

Two-line access technology for Cisco Routers In some cases, we need to implement dual-line access to ensure stable operation of the network and ensure reliable service quality. The following steps can be taken: 1. Configure the IP address of the Internet access interface, which is generally from China Telecom or China

Sometimes, in order to protect the security and privacy of our own users, we will establish an additional user for others to use. By default, Standard Users created in Windows can basically meet this control, however, if the IP attribute needs to be modified due to changes in the work environment, the user is not authorized to modify the attribute, which affects the use of users within a certain range, in this regard, Microsoft has created a separate user gr
