Course Description

This unit describes the performance outcomes, skills and knowledge required to undertake scripted programming tasks for networking related activities.

This course explores Linux and *nix through the command line, Bash scripting and Ubuntu. You will learn to work at the *nix command line, and transfer this knowledge to writing basic scripts.

Topics include
• Basic scripts, the development of writing scripts from the terminal to the script
• System security – separate user and root accounts, escalation of privileges, root via sudo su, sudo command, configuring the sudo’ers file with visudo.
• Standard permissions with owner and groups, read write and execute file permissions.
• File permissions: chmod, chown, chgrp, ls –al.
• File types, binary and text files, library files, symlinks. Compare with Windows dlls and shortcuts.
• Bash programming language, control structures. Functions, passing arguments from the command line, loops, if then, else and case statements, program return error code. Built in variables and PATH. The bash interpreter. Local variables and basic data types and manipulations with strings. Functions.
• Command line utilities relevant to networking. ps, netstat, ifconfig, ping, tail -f, htop
• *nix language in a Bash shell–mkdir, rm, cd, pushd, popd, pwd, ls, cp, mv -i, man, whoami, pipes, output redirection, echo, cat, grep, xterm &, pattern matching, “.” and “..” directories, ~, hidden files beginning with a period “.”, command line arguments, command line in scripts
• Scheduler through crontab with relative and absolute paths, logs, log files and logging messages
• vi editor skills
• *nix updates and software installation using # apt-get. In Ubuntu configuring the proxy server for apt-get update.

Overview of Assessment

Students must demonstrate an understanding of all elements of competency to be deemed competent. Skill based assessment.

A range of assessment methods are used to assess practical skills and knowledge, for example
• direct questioning combined with a review of portfolios of evidence
• review of authenticated documents from the workplace or training environment
• demonstration of techniques
