→identify and select appropriate fabric API for each task
* Has access to matrix.senecacollege.ca
'''Due Date:''' Please follow the three stages of submission schedule:* Check point 1: complete the detail algorithm for each task in this assignment by November 25, 2020. Name it as a2s_algorithm.txt and upload it to your github repository* Check point 2: complete the coding of your fabric commands file from the algorithm for each task by Dec 2, 2020. Name it as a2s_[Seneca_name].py (replace [Seneca_name] with your Seneca email user name) and upload it to your github repo by Dec 2, 2020.* Check point 3: complete the testing and debugging using your VM in myvmlab by Dec 4, and also submit your algorithm file (a2s_algorithm.txt), test results, and the fabric file (a2s_[Seneca_name].py) to Blackboardby April 12, 2021.
'''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 four new Fabric task tasks called userAdmin::* addUser(username):* findUser(username):* listUser():* listSysUser(): The userAdminaddUser(username) task should perform the following activities operations on a remote machine tosystem::* create a new user when necessary information is provided, and if the user name is already exist, the operation should fail.: The findUser(username) task should perform the following operations on a remote system::* scan the appropriate file(s) on the remote system and determine whether the named user exist or not and report accordingly.: The listUser() task should perform the following operations on a remote system::* delete an existing scan the appropriate file(s) on the remote system and produce a list of shell user when it is safe names on the system. Shell users are those users who can login to do sothe remote system and get a bash shell.: The listSysUser() task should perform the following operations on a remote system::* scan the appropriate file(s) on the remote system and produce a list of system user (non-shell) name on the system. System users are those users who will not get a bash shell.
== Tasks for this assignment ==
== Suggested work-flow for this assignment ==
=== create a <font color="blue">private</font> repository on github ===
* Use the same github account you have used for your assignment 1 repository.* Create a private repository named "ops435-a2ra2s" for this assignment.* Populate your private repository with appropriate files. Please check out the sample repository <b><font color='blue'>[https://github.com/rayfreeping/ops435-a2 here]</font></b>
=== Add collaborator to your ops435-a2r a2s private repository ===* Add your professor's github account as one of the collaborators to your ops435-a2r a2s private repository. This will allow your professor to pull the contents of your ops435-a2r a2s repository and also to review and suggest changes and fixes to your algorithm and/or python scriptyour fabric file.
* <b><font color='blue'>Make sure that your professor accepted your invitation from github.com.</font></b>
Follow the standard computation procedure: input - process - ouput when creating the algorithm document for this assignment.
==== input ====
* get what data (command line arguments/options) from the user using the functions provided by the argparse module* according to the arguments/options given at the command line, take appropriate processing action. do you need for each system administration operation
==== processing ====
* based on the file(s) specified, read the contents of each file what commands and use appropriate objects to store it* based on the command line arguments/options, process the data accordingly, which includes** data preprocessing (split a multi-day record into single day record)** record processing (preform required computation)in what order they should be executed
==== output ====
* output the required report based on the processed data==== identify and select appropriate python objects and functions ====The following python functions (to what information should be created, you may have more) are useful in handling the following sub-tasks:* reads login records from files and filters out unwanted records* convert login records into proper python object type so that it can be processed using as much built-in functions as possible * create function which generates daily usage reports by user and/or by remote host* create function which generates weekly usage reports by user and/display or by remote hostreturn
def listSysUser(): '''return a list of system (non-shell) user''' ... def findUser(name): '''find user with a given user name''' ... </pre> === Python script fabric file coding and debugging ===For each function, identify what type of objects should be passed to the function, and what type of objects should be returned to the caller.Once you have finished coding a functiontask, you should start a Python3 interactive shell, import your functions and manually test each function run it on matrix and verify its correctness.
=== Final Test===
Once you have all the individual function task tested and that each is working properly, perform the final test and compare with test data provided by your professor the sample tests and verify that your script produces fabric tasks produce the correct results before submitting your python program it on Blackboard. Upload all the files for this assignment 2 to your vm in myvmlab and perform the final test. == Sample login/logout records file and sample test run results==* can be found from the sample repository github.com/rayfreeping/ops435-a2
