Linux server uses network proxy
Since the campus server (Ubuntu) cannot be connected to the Internet, the Windows environment network proxy is used to connect to the Internet to download the required tool package
The steps are as follows
The prerequisite for using a network proxy must be that the Windows environment and the Linux environment must be able to ping each other (try to turn off the firewall).
Download the software CCProxy in the Windows environment to configure the CCProxy environment, click the (gear) button Option, configure the parameters as shown in the first picture, and then click Advanced to configure the parameters as shown in the second picture:1. Use pip3 to install the required packages: pip3 --proxy= 127.0.0.1:808 install package name
proxy=127.0.0.1:808 is to set the network proxy. Change 127.0.0.1 to the IP address of your own proxy network, 808 is the port, and the setting is consistent with the port of CCProxy. If you use the above statement, the error is as follows:from pkg_resources import load_entry_pointYou can use the following statement to install :ImportError: No module named pkg_resources
python -m pip --proxy=127.0.0.1:808 install
2. Use apt-get to install the required packages: sudo apt- get -o Acquire::http::proxy="http://127.0.0.1:808/" install package name
Acquire::http::proxy="http: //127.0.0.1:808/” To set up the network proxy127.0.0.1, change it to the IP address of your own proxy network, 808 is the port, set the port with CCProxy consistent.
The above is the detailed content of How to use network proxy on Linux server. For more information, please follow other related articles on the PHP Chinese website!

The core components of Linux include kernel, file system, shell, user and kernel space, device drivers, and performance optimization and best practices. 1) The kernel is the core of the system, managing hardware, memory and processes. 2) The file system organizes data and supports multiple types such as ext4, Btrfs and XFS. 3) Shell is the command center for users to interact with the system and supports scripting. 4) Separate user space from kernel space to ensure system stability. 5) The device driver connects the hardware to the operating system. 6) Performance optimization includes tuning system configuration and following best practices.

The five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.

Linux maintenance mode can be entered through the GRUB menu. The specific steps are: 1) Select the kernel in the GRUB menu and press 'e' to edit, 2) Add 'single' or '1' at the end of the 'linux' line, 3) Press Ctrl X to start. Maintenance mode provides a secure environment for tasks such as system repair, password reset and system upgrade.

The steps to enter Linux recovery mode are: 1. Restart the system and press the specific key to enter the GRUB menu; 2. Select the option with (recoverymode); 3. Select the operation in the recovery mode menu, such as fsck or root. Recovery mode allows you to start the system in single-user mode, perform file system checks and repairs, edit configuration files, and other operations to help solve system problems.

The core components of Linux include the kernel, file system, shell and common tools. 1. The kernel manages hardware resources and provides basic services. 2. The file system organizes and stores data. 3. Shell is the interface for users to interact with the system. 4. Common tools help complete daily tasks.

The basic structure of Linux includes the kernel, file system, and shell. 1) Kernel management hardware resources and use uname-r to view the version. 2) The EXT4 file system supports large files and logs and is created using mkfs.ext4. 3) Shell provides command line interaction such as Bash, and lists files using ls-l.

The key steps in Linux system management and maintenance include: 1) Master the basic knowledge, such as file system structure and user management; 2) Carry out system monitoring and resource management, use top, htop and other tools; 3) Use system logs to troubleshoot, use journalctl and other tools; 4) Write automated scripts and task scheduling, use cron tools; 5) implement security management and protection, configure firewalls through iptables; 6) Carry out performance optimization and best practices, adjust kernel parameters and develop good habits.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
