Daily start
Today is Saturday, six days of high-intensity learning ushered in the "great day of rest," Today's learning content is relatively easy, just start talking about Bai computer network-based time hope that through small video let us know, behind the more clearly beside the point, the atomic bomb manufacturing, high-speed rail operating procedures, airline ticketing process ......, so we see a funny little video in the morning bilibili. Bai afternoon took us read a blog post about "network penetration", talking about how bloggers to penetrate into their home wifi rub people's computers, behind mainly learned some ARP spoofing knowledge, step by step to like.
1. Problem Solving
1.1 kali download openvas error
Some students a mistake in downloading kali time, Bai may be prompted to update the source of a problem
Solution:
Open the sources.list file
leafpad /etc/apt/sources.list
Add the following update source (save the Chinese Academy of Sciences, Ali cloud and official sources to update)
# USTC deb HTTP: // mirrors.ustc.edu.cn/kali Kali as Free-Rolling main contrib non- deb-src HTTP: // mirrors.ustc.edu.cn/kali Kali as Free-Rolling main contrib non- # Ali cloud deb HTTP: // mirrors.aliyun.com/kali Kali as Free-Rolling main contrib non- deb-src HTTP: // mirrors.aliyun.com/kali Kali as Free-Rolling main contrib non- # Tsinghua University deb HTTP: / / mirrors.tuna.tsinghua.edu.cn/kali Rolling main contrib non-Kali as Free- deb-src HTTPS: // mirrors.tuna.tsinghua.edu.cn/kali Kali-Rolling main contrib non-as Free # Zhejiang deb http : //mirrors.zju.edu.cn/kali kali-rolling main contrib non-free deb-src http://mirrors.zju.edu.cn/kali kali-rolling main contrib non-free #东软大学 deb http://mirrors.neusoft.edu.cn/kali kali-rolling/main non-free contrib deb-src http://mirrors.neusoft.edu.cn/kali kali-rolling/main non-free contrib #官方源 deb http://http.kali.org/kali kali-rolling main non-free contrib deb-src http://http.kali.org/kali kali-rolling main non-free contrib deb http://mirrors.163.com/debian/ jessie main non-free contrib deb http://mirrors.163.com/debian/ jessie-updates main non-free contrib deb http://mirrors.163.com/debian/ jessie-backports main non-free contrib deb-src http://mirrors.163.com/debian/ jessie main non-free contrib deb-src http://mirrors.163.com/debian/ jessie-updates main non-free contrib deb-src http://mirrors.163.com/debian/ jessie-backports main non-free contrib deb http://mirrors.163.com/debian-security/ jessie/updates main non-free contrib deb-src http://mirrors.163.com/debian-security/ jessie/updates main non-free contrib

2. Study Notes
- kali update source: apt-get upgrade (in order to make the software upgrade), the USTC, Ali cloud and official update source copy and paste sourcelist file,
- Computer networking basics
Physical components: (core computer network) hardware, software, protocols
- Beep beep miles miles up the master may concern: My name is what a good teacher classmate, paper clips
- Barney back, carbanak, study the principles behind things, stimulate their own points of interest
- The difference between conflict and broadcast domains, and what conflicts, what is the domain of conflict, what is the broadcast domain, bridge
- Common service port number table and running
- Computer network model architecture analysis
- Computer network protocol layers and their functions
- ARP protocol
- See native ARP record ARP -A
- mp.weixin.qq.com/s?src11×tamp=1578664110 (a difficult network record penetration)
- webcam -list/webcam -list
- echo command, redirection, pipes, eth0 to eth1
3. Personal insights
Today, talking about the basics of computer network time, there are still a lot of knowledge not recall, and learn things easy to forget that learners need to overcome and continue to seek ways to better solve, in general, simple repetition is the most effective method of First, the meaning of which is after the "Replay" of lies. Today holiday, you can have a good rest, adjust the state re-start!
