1. Overview the main content of this chapter is to use ONPN to connect the branch router and headquarters route, and to use static route to achieve two-way mutual access. Second, set up headquarters settings: 1. Enable ONPN, click PPP, and select the following settings: click OK when you are finished. two。 Before setting up the account, we
Recovery background-accidentally deleted partitions in disk management, and there are very important files that can't be lost. You can see that the green area in the middle, 306.35G, is the partition that was deleted by mistake. Now, we can use the wrong partition in the dawning data recovery software to recover the number of recoveries.
Problems and solutions equipment and software manufacturers often encounter problems that are difficult to close. The hardware clock lock can accurately control the usage time of the software, but it cannot be used when the software expires. The license can be renewed after the final payment is paid. Products: elite 5-clock lock precise time control, encryption lock does not change with the change of computer time

OSPF network planning OSPF network planning can be considered from the following aspects: 1. The design steps of OSPF network are divided into the following steps: 1) requirements analysis: customer perspective is very important, in addition to consider the future development direction and so on. Reliability, delay, flow in network design
The idea of this script is to customize a key, and then calculate the real-time Nic traffic by looking at the values in the file / proc/net/dev. In fact, I am calculating an average. It is divided into in and out. If the script is executed every 1 minute, the calculated traffic

The purpose of PSK We all know that TLS needs to rely on asymmetric algorithms (RSK,EC,DS,DH...) to complete secret key exchange and identity authentication, but the time-consuming and computing resources of asymmetric algorithms are sensitive to resources or time-consuming scenarios, you want to optimize them.
Network transmission is divided into plaintext transmission and encrypted transmission, it is obvious that encrypted transmission is a secure transmission. Common plaintext transmission protocol: http,smtp,dns,pop3,imap4 the most common encrypted transmission: https2. The way of data encryption: symmetrical encryption: encryption party settlement
Overview of wireless local area network communication. Some people like to compare the communication of a wireless local area network to a wired local area network to plug a network cable connected to a computer into a 802.3 network port. I think there are similarities and great differences here. First of all, let's take a look at the basic communication process of wireless local area network. eight
