Accelerated Deploying Ubuntu Server Edition

Description:
This two-day accelerated course is a condensed version of the five-day course “Deploying Ubuntu Server Edition”. It is designed to provide professionals who already have significant systems administration experience with another Linux distribution with a rapid “conversion course” to the Ubuntu-specific aspects of managing and deploying Linux systems in an enterprise environment.
Although the course covers the same broad outline as the five-day course, emphasis is placed on areas where Ubuntu differs from other Linux distributions; for example, installation, the management of packages and repositories, ufw (Ubuntu firewall) and AppArmor.

After completing this course, participants will be able to:
•    Install and deploy Ubuntu Server in an enterprise environment
•    Perform an advanced, automated installation using Kickstart
•    Manage disk partitions, logical volumes and file systems
•    Install and manage software packages using command-line tools
•    Create proxies and mirrors for Ubuntu repositories
•    Create and deploy virtual machines using  KVM and libvirt
•    Automate updates and use Landscape to manage client systems
•    Maintain user-level security
•    Configure a simple firewall
•    Set up a mail server using Postfix and Dovecot
•    Constrain applications with AppArmor mandatory access controls
•    Monitor server load and status
•    Define and implement a backup strategy
•    Install and configure LDAP directory service, Kerberos and AD integration

Who Should Attend
This course is designed for experienced system administrators who hold an RHCE or similar certification and wish to migrate or expand their skill set into Ubuntu Server. The course assumes a substantial level of competence in working with and configuring Linux at the command line,  and that students have significant real-world experience with Linux system administration.  It is not intended for those with only a Microsoft system administration background.
Administrators with less than five years of active, professional experience of a Linux or UNIX distribution are recommended to take the full 5-day “Deploying Ubuntu Server Edition” course.

Pre-requisites
Attendees should already have:

• An Ubuntu Certified Professional certification and/or;
• RHCE certification and/or,  the equivalent training and working knowledge of RedHat (or other RPM-based distributions), and/or
• A sound working knowledge of system administration of some other version of UNIX or Linux such as Solaris, HPUX or SUSE.

This is an advanced, fast-paced course and almost all work is done from a Linux command prompt, not with graphical tools. Attendees must be able to work effectively on the command line and have familiarity with:

• The bash shell, including
  • filename wildcards, command completion, command history
  • environment, variables and simple scripting
• ssh , including setting up public/private key authentication
• Process text using standard filters and pipelines
  • grep, head, tail, wc, sort, awk, sed, ...
• File system management commands: ls, cp, mv, rm, mkdir, chmod, chown, ...
• Commands to list and manage processes: ps, top, vmstat, /proc, ...
• TCP/IP networking and configuration: static and dynamic (DHCP)
• The boot process  e.g. GRUB, init, inittab and the “System V” runlevels
• Package management (not necessarily Debian, could be RPM or pkgadd)
• Key system configuration files such as /etc/passwd, /etc/fstab
• An editor that doesn't need a mouse, such as vi or emacs  

Students receive    

• Individual student packs consisting of:
  • Student Course Guide
  • Ubuntu 10.04 LTS desktop and server CDs
  • Ubuntu note pad and pen
  • Ubuntu gift (it's a surprise!)
• Free access to Landscape systems management and monitoring service.
• Certificate of completion, following minimum 80 per cent attendance and active participation, as determined by the instructor.
