The document outlines topics to be covered in a Monday presentation on Linux fundamentals, including Unix basics, Linux installation management using CentOS, file systems, user and group management, and secure shell (SSH). Specifically, it will discuss the history and types of Unix, the layers of Unix including the kernel and shell, hardware requirements and installation methods for CentOS, commands for adding users and groups, and using SSH to remotely access machines and transfer files securely.

Topics

3. Unix Basic
 Unix is an operating system name for time-sharing system
researched and developed by AT&T Bell Labs in 1969
 Two Types of Unix :
- BSD (Berkeley Software Distribution)
- System V (System Five)

4. Unix Basic
 Unix Layers :
- Unix consists of three parts:
1. Unix Kernel
2. Shell
3. Command Processes or Utilities

5. Linux Installation Management – CentOS
 A Linux distribution that attempts to provide a free, enterprise-
class, community supported computing platform
 A free version of RHEL, so it’s good if you want a stable platform
that will be supported for a long time

6. Linux Installation Management – CentOS
 Hardware Requirement
 Hardware Element
 Hardware Compatibility Lists
 Installation Methods (Media like CD/DVD, USB, etc..)

7. File System

8. User and Group Management
 To control access to the system’s files, directories and peripherals
 Root user has complete access to OS and its configuration
 useradd –m –g[initial_group] –G[additional_groups] –s[login_shell]
[Username]
 groupadd [groupname] –g[groupid]

9. User and Group Management

10. Secure Shell – (SSH)
 Used to log into a remote machine and execute commands(replacing telnet and
rlogin
 Default - TCP 22 port
 Also support X11 connections (VNC)
 Can transfer files using SSH File Transfer(SFTP) or secure copy(SCP) protocols

11. Secure Shell – (SSH)
