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

  • 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

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.
