Introduction: explanation of 1.expect 2. The instance operation automatic login script expect explains that expect allows us to automatically log in to the remote machine and execute commands remotely. Of course, automatic login and automatic remote can also be realized by using key authentication without password.

Internet service provider Sandvine recently released a report that mentioned a very interesting phenomenon: compared with last year's data, encrypted network traffic (SSL) is showing explosive growth this year. This change is evident in Europe: compared with 1.47% last year.
1. Requirements: the project needs to connect an external USB network card for respberry pi, and some network settings need to be made for this network card when respberry pi starts. two。 Implementation plan: (1) add the following code to the / etc/rc.local file
Virtual machine network configuration difference bridging: peer-to-peer machine: host and virtual machine are connected to the switch at the same time, and the virtual machine is equivalent to a real host of the switch. NAT: network address translation, the host is equivalent to routing, the virtual machine connects to the host to access the Internet host-only: host and
Base64. As the name implies, it is a way to represent binary data based on 64 printable characters. (it is not an encryption algorithm). For 64 printed characters, we need 6 binary bits to fully represent the word. So how do we use eight binary bits to show that only six are needed?
After cracking, set the proxy port 8888ssl proxy settings allow all addresses to connect to the mobile phone to obtain the certificate before installing the certificate on the computer, you need to trust it. Help-- > ssl-proxying-- > Install Charles Root C
The effect is as follows: if you modify the icon and change it into a text or picture icon, it will be more confusing. Double-click and run it. We can see that the specific operation plan is also displayed in the process: (select file rename) (2) (3) enter gnp (4) modify the previous name gpedi again
In the OSI model and the tcp/ip model, the application sends some data to the server, which takes many paths to reach the server. On the way of sending, because the data is plaintext and anyone can view it, it brings risk to the data. Therefore, encryption is necessary. Common key algorithms

NAT is divided into static NAT, dynamic NAT, and PAT1, static NAT: private ip and public network ip one-to-one mapping, port number does not change, generally used for LAN access. 2. Dynamic NAT: a many-to-many mapping between multiple private ip and multiple public network ip (address pool)
Net- policy routing 1. Policy routing strategy means that the routing of IP packets is mainly based on some policies laid down by the network administrator according to the needs. For example, we can have such a strategy: "all packets from net A, choose the X path; others choose the Y path", or "so"
Because the network circulation of the local area network is not carried out according to the IP address, but according to the MAC address. Therefore, the MAC address is forged as a non-existent MAC address on A, which will lead to network failure, and A cannot Ping C! This is a simple ARP deception. In each machine
Zero-flow sharing software based on WIFI Direct is no longer a new concept. There are three good ones on the market. Later, I will talk about my thinking. I always wanted to do a software called Kuaixian, but it was a pity that the business model of the tool software was too simple, and later I did it in a certain broadcast.

Network shunt | Traffic acquisition and shunt implementation of high-speed backbone network 1 Traffic acquisition | the so-called traffic collection of the network shunt is to parse and unframe the network traffic through the physical layer and data link layer to achieve the acquisition of IP original messages. The backbone network traffic collection system is a kind of traffic to the backbone network.
