Essential Kali Linux Commands for Ethical Hacking Newbies

Kali Linux is a popular Linux distribution used for ethical hacking and penetration testing. As a new user, navigating through the various commands and tools can be overwhelming. In this article, we will cover the essential Kali Linux commands that every ethical hacking newbie should know.

1. Basic Navigation Commands

Before we dive into the advanced commands, let’s start with the basic navigation commands that will help you navigate through the Kali Linux system.

• cd: Change directory. This command is used to navigate through the file system. For example, cd /root will take you to the root directory.
• pwd: Print working directory. This command will display the current directory you are in. For example, pwd will display the path of the current directory.
• ls: List files and directories. This command will display the files and directories in the current directory. For example, ls -l will display the detailed list of files and directories.
• mkdir: Make a directory. This command is used to create a new directory. For example, mkdir mydir will create a new directory named "mydir".
• rm: Remove files and directories. This command is used to delete files and directories. For example, rm -rf mydir will delete the directory "mydir" and all its contents.

2. Package Management Commands

Kali Linux uses the APT package manager to install and manage software packages. Here are some essential package management commands:

• apt update: Updates the package list to ensure you have the latest package versions.
• apt install <package_name>: Installs a new package. For example, apt install nmap will install the Nmap package.
• apt upgrade: Upgrades all installed packages to the latest version.
• apt remove <package_name>: Removes a package. For example, apt remove nmap will remove the Nmap package.
• apt autoremove: Removes unnecessary packages that were installed as dependencies.

3. Network Configuration Commands

As an ethical hacker, you will need to configure your network settings to connect to the target system. Here are some essential network configuration commands:

• ifconfig: Displays the network interface configuration. For example, ifconfig eth0 will display the configuration of the eth0 interface.
• ip addr: Displays the IP address of the system. For example, ip addr show will display the IP address of the system.
• route: Displays the routing table. For example, route -n will display the routing table.
• netstat: Displays the network statistics. For example, netstat -an will display the network statistics.
• ssh: Connects to a remote system using SSH. For example, ssh user@192.168.1.100 will connect to the system with IP address 192.168.1.100.

4. File Transfer Commands

As an ethical hacker, you will need to transfer files between systems. Here are some essential file transfer commands:

• scp: Secure copy command. This command is used to transfer files securely between systems. For example, scp file.txt user@192.168.1.100:/home/user/ will transfer the file "file.txt" to the system with IP address 192.168.1.100.
• rsync: Synchronize command. This command is used to synchronize files between systems. For example, rsync -avz file.txt user@192.168.1.100:/home/user/ will synchronize the file "file.txt" with the system with IP address 192.168.1.100.
• ftp: File transfer protocol command. This command is used to transfer files using the FTP protocol. For example, ftp 192.168.1.100 will connect to the system with IP address 192.168.1.100 using FTP.

5. System Information Commands

As an ethical hacker, you will need to gather system information to identify vulnerabilities. Here are some essential system information commands:

• uname -a: Displays the system information, including the kernel version and hostname.
• lspci: Displays the list of PCI devices.
• lsusb: Displays the list of USB devices.
• ifconfig -a: Displays the network interface configuration, including the IP address and MAC address.
• netstat -plnt: Displays the network connections, including the process ID and protocol.
