Late Penalty: 20% per school day, and note that in order to pass this course, this assignment must be completed satisfactorily, i.e. a grade of 50% or more.

Overview

Study the Fabric API run(), sudo(), local(), and put() and utilize them to create a new Fabric task called userAdmin()

The userAdmin() task should perform the following activities on a remote machine to:

• create a new user when necessary information is provided
• delete an existing user when it is safe to do so.

Tasks for this assignment

In this assignment, you should perform the following activities:

1. Complete a detail algorithm for the following FOUR system administrator operations:
   1. add a user account to a Linux system (task name addUser)
   2. determine whether a given user name exist on a Linux system (task name findUser)
   3. get a list of user account name with a command shell on a Linux system (listUser)
   4. get a list of system account name without a command shell on a Linux system (listSysUser)
2. Create a corresponding fabric task using the fabric API to automate the above four system administrator operations.
3. Test and debug your fabric file using your assigned VM in myvmlab.senecacollege.ca

Sample outputs from running your Fabric task file

Name of fabric file: a2s_rchan.py

list of fabric commands

[raymond.chan@mtrx-node05pd lab8]$ fab -f a2s_rchan.py -l
Available commands:

    addUser      add a user with given user name to remote system
    findUser     find user with a given user name
    listSysUser  return a list of system (non-shell) user
    listUser     return a list of shell user on a remote system

Test run the addUser task

[raymond.chan@mtrx-node05pd lab8]$ fab -f faba2.py --host=myvmlab.senecacollege.ca --port=7598 addUser:ops435
[myvmlab.senecacollege.ca] Executing task 'addUser'
[myvmlab.senecacollege.ca] ...

Done.
Disconnecting from myvmlab.senecacollege.ca:7598... done.

Test run the findUser task

[raymond.chan@mtrx-node05pd lab8]$ fab -f faba2.py --host=myvmlab.senecacollege.ca --port=7598 findUser:ops435
[myvmlab.senecacollege.ca] Executing task 'findUser'
...
...

[myvmlab.senecacollege.ca] out: 

Found user ops435 on the system.

Done.
Disconnecting from myvmlab.senecacollege.ca:7598... done.

Another test run:

[raymond.chan@mtrx-node05pd lab8]$ fab -f faba2.py --host=myvmlab.senecacollege.ca --port=7598 findUser:seneca
[myvmlab.senecacollege.ca] Executing task 'findUser'
...
...
[myvmlab.senecacollege.ca] out: 

User seneca is not on the system.

Done.
Disconnecting from myvmlab.senecacollege.ca:7598... done.

Test run the listUser task

[raymond.chan@mtrx-node05pd lab8]$ fab -f faba2.py --host=myvmlab.senecacollege.ca --port=7598 listUser
[myvmlab.senecacollege.ca] Executing task 'listUser'
...
...

['root', 'raymond', 'chan', 'ops435']

Done.

Test run the listSysUser task

[raymond.chan@mtrx-node05pd lab8]$ fab -f faba2.py --host=myvmlab.senecacollege.ca --port=7598 listSysUser
