Linux Advanced System Administration (LPI)

This instructor led Linux Advanced System Administration (LPI) training course is designed to teach the advanced administration, security, networking and performance tasks required on a Linux Enterprise system.

More details

More info

Targeted to closely follow the official LPI curriculum (generic Linux), this course together with the Linux System Administration course will enable the delegate to work towards achieving the LPIC-2 qualification.

Skills Gained

The delegate will have knowledge in all, and practise in some, of the following:

  • Perform administrative tasks with supplied tools such as YAST
  • Advanced network configuration
  • Network troubleshooting
  • Configuring network services LDAP, DNS and DHCP
  • Sharing Window and Linux resources with SAMBA
  • Sharing Linux network resources with NFS
  • Configuring FTP and NFS
  • Configuring network services APACHE and SQUID
  • Managing the Logical Volume Manager (LVM)
  • Managing software RAID
  • Centralised storage with iSCSI
  • Monitoring disk status and reliability with smartd
  • Firewall configuration
  • Pluggable Authentication Modules (PAM)
  • Kernel installation and compilation
  • Compiling software from source
  • System performance monitoring
  • Hardware configuration with hotplug and udev

Who will the Course Benefit?

The Linux Advanced System Administration (LPI) training course is suitable for Linux System Administrators who need to acquire advanced administration knowledge of the key administrative, networking and security tasks required on Linux within the Enterprise. The typical delegate will be working in an environment using several different Linux distributions and therefore knowledge of skills common to all the different Linux distributions is required. For the purpose of practical exercises, SUSE Linux will be used.

Note: Should the delegate only require knowledge of Red Hat Linux then they should instead consider attending our range of Red Hat Linux Administration courses.

Course Objectives

On completion of this course the delegate will have in-depth technical knowledge of what is required to administer Linux within the Enterprise. They will have gained practical experience of configuring administrative, networking and security aspects of a Linux Enterprise system to an advanced level. The delegate will possess the essential knowledge required to work towards achieving the Linux Network Professional LPIC-2 qualification.

Examinations

The Linux Advanced System Administration (LPI) training course will teach some of the necessary skills to enable the delegate to work towards achieving the LPIC-2 certification. Together with the Linux System Administration course, this course is suitable for delegates intending to sit the LPI 201 & LPI 202 examinations.

Before taking any exam, ensure you have the recommended experience. The LPI website lists all exam requirements and these are updated regularly.

Exams are not included as part of the course.

Requirements

Experience of administering Linux in an Enterprise environment to the level covered in the Linux System Administration course. Knowledge of Linux Shell Programming to the level covered on the Linux Shell Programming course would also be beneficial.
