Linux Tutorials
Our Linux tutorials offer a systematic way to master the open - source operating system. They cover command - line operations, system administration, and shell scripting, suitable for both beginners and experienced users. With free labs and practical examples, you'll gain hands - on experience in Linux environments. Our interactive Linux playground allows you to practice commands and scripts in a simulated terminal.

Linux
Metasploit Basic Post-Exploitation
In this lab, you will learn the basic post-exploitation techniques in Metasploit, including interacting with sessions, running shell commands, and transferring files.
Linux
Metasploit Simple Exploit Execution
In this lab, you will learn the basic workflow of exploiting a vulnerable service using the Metasploit Framework. You will target a known backdoor in VSFTPD 2.3.4 to gain a shell on the target system.
Linux
SSH Enumeration and Key-Based Access
In this lab, you will learn to enumerate an SSH service using `nmap`, exploit a weak key-based authentication misconfiguration to gain shell access, and retrieve a flag. This exercise focuses on SSH security best practices.
Linux
HTTP Enumeration and Directory Traversal
In this lab, you will learn to perform HTTP service enumeration and exploit a directory traversal vulnerability. You'll use `nmap` to identify a web server, then use `curl` to read a restricted file outside the web root and capture the flag.
Linux
User Account Creation
In this lab, you will learn the fundamental Linux commands for user account management, including creating, modifying, and deleting user accounts, and granting administrative privileges.
Linux
Rsync Enumeration and Anonymous Sync
In this lab, you will learn to enumerate and exploit a misconfigured Rsync service. You'll use `nmap` to detect the service, connect anonymously to sync files from a remote target, and retrieve a flag, highlighting risks in backup synchronization services.
Linux
SMB Enumeration and Guest Access
In this lab, you will learn to perform Server Message Block (SMB) enumeration. You'll use `nmap` to identify the SMB service, exploit a guest access misconfiguration with `smbclient`, and retrieve a flag from a shared directory, simulating a common network vulnerability.
Linux
RDP Enumeration and Weak Password Access
In this lab, you'll enumerate Remote Desktop Protocol (RDP) services, identify vulnerabilities, and gain access using weak credentials. Use `nmap` for scanning, `xfreerdp` for connection, and retrieve a flag from the remote desktop session.
Linux
DAY 09: The Backup Sentinel
In this challenge, you'll act as a system administrator to master Linux backup and recovery, protecting critical data using `tar` and `cron`.
Linux
Telnet Brute Force and Weak Credentials
In this lab, you'll enumerate weak credentials for a Telnet service using a wordlist. You will scan with nmap, use hydra for a brute-force attack, and gain access to a target system to retrieve a flag, highlighting the risks of weak passwords.
