Linux for network engineers

Description

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.

What will you learn

• 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.
