Linux for network engineers

A 5 day
HANDS ON
training course

Linux training course description

A Linux foundation appropriate for all flavours of Linux, focussed on getting network engineers up and running with Linux. The command line is used throughout. The course progresses from the basics of Linux commands onto useful tools such as grep, then shell features such as piping and then onto shell scripting. Administration aspects covered are the tasks network engineers are most likely to encounter such as software installation. Hands on exercises concentrate on network related tasks such as installing net-snmp and using shell scripts to provide network automation.

Key outcomes from this course

By the end of the course delegates will be able to:
  • Use Linux commands to perform a variety of tasks from manipulating files to handling processes.
  • Create and edit files with vi.
  • Work with permissions.
  • Write simple shell scripts.
  • Install software packages.
  • Configure base networking.

Why Choose Us

SNT trainers score an average of over 90% on the three main areas of:
  • Ability to teach
  • Technical knowledge
  • Answering questions
“Excellently presented by a very knowledgeable and enthusiastic trainer.” P.D. General Dynamics

We limit our maximum class size to 8 delegates; often we have less than this. This ensures optimal interactivity between delegates and instructor.
"Excellent course. The small class size was a great benefit…" M.B. IBM

We write our own courses; courseware does not just consist of slides and our slides are diagrams not bullet point text. A typical chapter provides clearly defined objectives with a chapter overview, slides with text underneath, a quiz at the end to check the learning of the students. Hands on exercises are at the end and are used to reinforce the theory.
