Usage 

To use this plugin,follow below two steps.

1) Enable "Enable user-IP mapping",in Quiz Settings(it can be done while creating the quiz

     or after creating,by visiting Edit Settings)

2) Check "Allow Unmapped" if you want to allow the unmapped users to attempt the quiz.If left 

    unchecked,unmapped users would not be allowed to attempt the quiz.

   Fig. 5  Select Yes to enable the plugin.

3) User-IP mapping can be managed in the quiz administration block.

   Quiz administration block->Access Rule->User-IP Mapping->Import user-IP mappings.


    Fig. 6 Navigate to quiz administration block to manage user-IP mappings.



 

    Fig. 7 Import new mappings or edit existing ones.




  Fig. 8 Upload csv file containing list of mappings.


4) User-IP mappings are quiz dependent.For every quiz you wish to use this plugin,a mapping list should be uploaded again from their respective quiz administration block.

5) A quiz can have multiple mapping uploaded,though only the latest mapping would be considered to restrict the student from attempting the quiz.


Requirement of the mapping file to be uploaded are:

1) The file should be in CSV(comma separated values) format.

2) It should have two fields.First field should be for usernames and second for IP addresses.

Fig. 9 Sample csv mapping file

3) Both the fields(username,ip) are required field,if even any one of the field is missing would lead to an error and the upload wouldn't proceed untill all the required fields are present in the csv file.Only registered and enrolled user's mapping would be uploaded rest all mappings will be skipped



  Fig. 10 Error thrown as both username and ip entries are not present in all records.


   Fig. 11 List contained records having users not registered and not enrolled.


      Fig. 12 Not registered and not enrolled users mapping will skipped while uploading.


    Fig. 13 An sample file with accepted mapping records.


      Fig. 14 All mappings were successfully added.

4) There should be one to one mapping between user and IP address,i.e each user should be mapped to only one IP address (in multiple mapping uploads,previous alloted IP would override with the latest one by default.)
