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.

Element:

Test and debug code

Performance Criteria:

Engineer, document and conduct simple tests to confirm code meets design specification
Identify areas that are not covered or are covered incorrectly in the script
Take action to ensure that code complies with security policy
Take action to ensure that code operates with proper permissions
Use script debugging techniques suitable for use with scripting language to detect and resolve errors of syntactical, logical and design origin

Element:

Use operating system tools

Performance Criteria:

Use searching and sorting tools to select information from the logging output of operating system (OS)
Implement controls to ensure that where significant events occur, script creates and maintains a log of operations via operating system logging mechanism
Register and run scripts with OS scheduling facility


Learning Outcomes


Develope scripted programming abilities.  Develope skills in BASH. 

This course contributes to the development of the following capabilities:
• Develop shell scripts
• Using Linux at the command line
• Monitor processes by command line tools and the GUI.
• Identify and manage standard permissions
• Write a basic menu program
• Modify and testing your code
• Documenting code


Details of Learning Activities

Develope skills and knowledge required to undertake scripted programming tasks for networking-related activities.

  • learning bash scripting
  • learning vi
  • writing scripts
  • exploring system utilities and command line arguments
  • test and debug code
  • write and document a utility

Class pracs, classroom discussion are part of the learning activities, as well as work-based experiences and activies.

Internet hyperlinks to technical documents and references including Youtube will be used as a learning tool and resource.

Learning activities may be modified during the semester to meet the needs of students in the current program and the needs of their workplace.

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
 


Assessment Tasks

Skills Based Assessments:
These assessments can be done either at RMIT or at the workplace providing appropriate equipment is available.
All pracs need to be satisfactorily completed to pass the course.
