How to configure Debian Sniffer

Configuring a network sniffer (such as Wireshark) in a Debian system requires several steps, including installing the necessary software packages, configuring the network interface, and running the sniffing command. It is important to note that network sniffing may involve security and privacy issues, so before doing sniffing, make sure you have legal authority and comply with all relevant laws, regulations and privacy policies.

This article takes Wireshark, a commonly used network protocol analyzer, as an example, to explain its installation and configuration on the Debian system:

Install Wireshark on Debian

Open the terminal.
Update the package list:

 sudo apt update

Install Wireshark:

 sudo apt install wireshark

Configure Wireshark

Start Wireshark.
When running for the first time, Wireshark prompts you to select the network interface to monitor. Select the right interface.
To save the captured data packet, select Save in the File menu and specify the file name and save location.

Please note that configuring Wireshark may require administrator privileges to access certain network interfaces.

Again, before performing network sniffing operations, please make sure that your behavior is legal and compliant and fully understand the relevant laws and ethical norms.

Linux Operations: Security and User ManagementMay 06, 2025 am 12:04 AM

Linux user management and security can be achieved through the following steps: 1. Create users and groups, using commands such as sudouseradd-m-gdevelopers-s/bin/bashjohn. 2. Bulkly create users and set password policies, using the for loop and chpasswd commands. 3. Check and fix common errors, home directory and shell settings. 4. Implement best practices such as strong cryptographic policies, regular audits and the principle of minimum authority. 5. Optimize performance, use sudo and adjust PAM module configuration. Through these methods, users can be effectively managed and system security can be improved.

Linux Operations: File System, Processes, and MoreMay 05, 2025 am 12:16 AM

The core operations of Linux file system and process management include file system management and process control. 1) File system operations include creating, deleting, copying and moving files or directories, using commands such as mkdir, rmdir, cp and mv. 2) Process management involves starting, monitoring and killing processes, using commands such as ./my_script.sh&, top and kill.

Linux Operations: Shell Scripting and AutomationMay 04, 2025 am 12:15 AM

Shell scripts are powerful tools for automated execution of commands in Linux systems. 1) The shell script executes commands line by line through the interpreter to process variable substitution and conditional judgment. 2) The basic usage includes backup operations, such as using the tar command to back up the directory. 3) Advanced usage involves the use of functions and case statements to manage services. 4) Debugging skills include using set-x to enable debugging mode and set-e to exit when the command fails. 5) Performance optimization is recommended to avoid subshells, use arrays and optimization loops.

Linux Operations: Understanding the Core FunctionalityMay 03, 2025 am 12:09 AM

Linux is a Unix-based multi-user, multi-tasking operating system that emphasizes simplicity, modularity and openness. Its core functions include: file system: organized in a tree structure, supports multiple file systems such as ext4, XFS, Btrfs, and use df-T to view file system types. Process management: View the process through the ps command, manage the process using PID, involving priority settings and signal processing. Network configuration: Flexible setting of IP addresses and managing network services, and use sudoipaddradd to configure IP. These features are applied in real-life operations through basic commands and advanced script automation, improving efficiency and reducing errors.

Linux: Entering and Exiting Maintenance ModeMay 02, 2025 am 12:01 AM

The methods to enter Linux maintenance mode include: 1. Edit the GRUB configuration file, add "single" or "1" parameters and update the GRUB configuration; 2. Edit the startup parameters in the GRUB menu, add "single" or "1". Exit maintenance mode only requires restarting the system. With these steps, you can quickly enter maintenance mode when needed and exit safely, ensuring system stability and security.

Understanding Linux: The Core Components DefinedMay 01, 2025 am 12:19 AM

The core components of Linux include kernel, shell, file system, process management and memory management. 1) Kernel management system resources, 2) shell provides user interaction interface, 3) file system supports multiple formats, 4) Process management is implemented through system calls such as fork, and 5) memory management uses virtual memory technology.

The Building Blocks of Linux: Key Components ExplainedApr 30, 2025 am 12:26 AM

The core components of the Linux system include the kernel, file system, and user space. 1. The kernel manages hardware resources and provides basic services. 2. The file system is responsible for data storage and organization. 3. Run user programs and services in the user space.

Using Maintenance Mode: Troubleshooting and Repairing LinuxApr 29, 2025 am 12:28 AM

Maintenance mode is a special operating level entered in Linux systems through single-user mode or rescue mode, and is used for system maintenance and repair. 1. Enter maintenance mode and use the command "sudosystemctlisolaterscue.target". 2. In maintenance mode, you can check and repair the file system and use the command "fsck/dev/sda1". 3. Advanced usage includes resetting the root user password, mounting the file system in read and write mode and editing the password file.
