AUDIENCE:   Computer users who will be required to administer one or more RHEL5, Fedora or CentOS 5 system. PREREQUISITES:   No previous experience with a UNIX or Linux system is required, although delegates may benefit from attending our UNIX/Linux Essentials course. DURATION:   4 days. Hands on. OBJECTIVES:   Red HatTM Enterprise Linux (RHEL) is finding its way into business, education and government. Due to its outstanding reliability, performance and low cost, RHEL is being used extensively for file, database and web server applications. The Red HatTM Enterprise Linux 5 Essentials & Administration course is designed to cover in detail the essential topics required to administer these systems. The Red HatTM Enterprise Linux 5 Essentials & Administration course assumes the delegate has no prior knowledge of a Unix or Linux system and therefore starts from the basics. The course then moves on to show delegates how to manage their RHEL systems including adding user accounts; install software and hardware; access disk devices & boot-up and shut down systems. At the end of this course, delegates will be able to: - Understand the use of Linux - Log-in and log-out of the system - Navigate the file system - List files and directories - Set ownership's and permissions - Manipulate files and directories - View files - Use filters and pipes - Use wildcards, meta-characters & regular expressions - Use the vi editor for basic editing - Install RHEL5 from DVD - Install RHEL5 using KickStart - Boot & shutdown RHEL and understand the boot process - Administer the Linux file system & partition disks - Add software & packages - Add, delete and manage users - Perform basic network configuration - Add, delete & manage the print system - Perform batch processing tasks - Monitor and maintain log files - Understand the kernel and how it is recompiled - Introduction to Linux RAID & Logical Volume Management COURSE CONTENT:   1. RHEL5 Introduction  Obtaining RHEL5  RHEL5 versions  Rebuild versions of RHEL  RH Certification Program 2. Introduction to the XWindow system  The XWindow system  Selecting a window manager  Logging into Linux  The Gnome window manager  The KDE window manager  Using the Firefox browser to access the Internet 3. Using the Linux environment  cat, tac, zcat, head, tail, uniq, & sort commands  Extracting lines from files  Replacing text  Formatting files  Comparing Files  File conversion tools 4. Linux File Structure  The file structure hierarchy  File naming conventions  The pwd & cd commands  Creating & removing directories  Copying, renaming and moving files & directories  Using links  Deleting files and directories 5. Text Editors  The vim editor  Graphical based editors 6. The Linux shell environment  Special & meta-characters  Local & environmental variables  History mechanism 7. File System Security  Access Permissions  Access Rights  Changing permissions  Permission masks 8. Advanced Shell Functionality  File descriptors  Shell redirection  File & devices  Using pipes  Using shell aliases 9.  Unix Filters & Tools  Tools & pipelines  Using tr, cut, sort, & uniq  Command substitutions 10.  Advanced Text Manipulation Tools  Using the find command  Comparing files  Pattern matching  Using grep, sed & awk 11.  Network Access to Linux  Introduction to Linux networking  The ping command  Using telnet & ftp  Using the secure shell package 12.  Hardware & Installation  Hardware compatibility  CPU, RAM, Hotswap Buses  RHEL5 installation  Post install steps  Network based installation 13.  The Boot Process  BIOS initialisation  The GRUB boot loader  Kernel initialisation  The init process and inittab file  Controlling services  System configuration files 14.  The Linux Filesystem  Partitioning hard disks  Managing filesystems  The automounter  Access control lists 15.  Package Management  The Red Hat package manager  The Red Hat Network  Using pup, pirut and yum  Using KickStart to automate installation 16.  User Administration  User account Management  Basic user environment  Shell configuration files  Disk quotas  Special groups  Pluggable Authentication Module  NIS & LDAP clients   17.  System Administration Tools   Network configuration  The CUPS print system  Using cron & at  Managing log files NT08/01
