This is because you need to manually specify the IP address, gateway, and DNS server connection mode, and use the proxy server to access the Internet. Carefully check the computer's network settings.Ii. DNS server problemsWhen ie cannot browse the Web page, try the IP address first. If yes, it should be a DNS problem, the DNS problem m

Principles of access layer optical cables
According to the principle of network layering, we divide the domestic network cable into a relay layer and an access layer. The access layer optical cable refers to the optical fiber cable between the local bureau station and the u
If a computer on a local area network is infected with a virus, there is a risk that all computers will be "infected" by the entire LAN. In order to control the access security of the common computer in the LAN, we can use the Special Network Access Protection function of Wi

Introduction:The squid service provides powerful Access Control functions. By defining various ACLs (Access Control List and Access Control List), these lists contain certain filtering and Con
Broadband access networks are still developing very rapidly. Here we mainly introduce the new proprietary intellectual property rights process-based routing operating system, it includes comprehensive service support capabilities, in-depth packet detection capabilities, and comprehensive QoS Assurance capabilities. In the process of increasing bandwidth users and services and IP address-based telecommunication networks, as operators demand more busine
that there is no problem, but it has not actually solved this problem, first, let's look at the imperfect methods on the network:

The most characteristic of the access layer switch is that it has the flow control function, but it can only carry on the simple speed limit to each kind of flow through the port, the function is not quite complete.
Using the grasping Bag tool, the author often captures the abnormal packets with large flow, which consumes the network bandwidth and consumes the r
There are many types of access control list ACLs in Huawei 3COM devices. Different types of ACLs are applied in different scenarios. The simplest of them is the standard access control list. It uses the source IP address in the IP package for filtering and uses the access

If a match is given, either release or deny access. The working process is: TCPDWork in a position where TCP pack documentation is to pass, wit

To protect their Cisco networks, many administrators are busy with what traffic can be allowed to pass through network devices, and how to restrict the unique information exchanged between mail route upgrades and other routers. The access control list (ACLs) usually solves these problems quite simply. The security of network
