TASK:

It is required that user can connect to open WiFi network (probably running Mikrotik hotspot system) and upon browsing he will see the login page with REGISTER option as well. User can self register his account on radius billing system by using PHP FORM[for example can be used in FREE WiFi environment, exhibition, conference rooms, resorts etc].

It is also useful if you want to provide trial/free internet access but want to log all the required info , like mobile numbers, contacts, and there usage with control.

Upon submissions, PHP form will execute Linux bash script with the supplied data, and then it should perform various checks , example.

User must enter no less or more then 11 numeric digits in MOBILE field.
User must enter no less or more then 13 numeric digits in CNIC field.
User must enter correct CAPTCHA image code in order to submit the form. It is required in order to prevent BRUTE force attack using automated scripting.
If the user is registering for the first time, his account will be registered with specific service (the service must be added by admin, and its name is configurable in reg.sh script file. The system will send SMS (and print screen , you can configure it as per the requirements) to user mobile number supplied in the form with the login , validity and other information.
The user should be allowed 3 hours for the current day (or as per the profile configured in reg.sh)
If the user consumed 3 hours within the same date and try to register again, he will be denied with the information message that he have already registered with the same mobile and account status will be provided like still ACTIVE or EXPIRED and that he should try again next day (date).
If the user still have balance and account is active, he should be informed accordingly.
If the user have expired (dueto DATE OR UPTIME hours limit) and next date arrived, he can register again, and INFO SMS message (and print screen , you can configure it as per the requirements) will be sent to use informing that his previously registered account got renewed with the login , validity and other information.

Components Used:

1- Ubuntu
2- Apache Web Server
3- Radius Manager as Billing system in working condition
4- GSM Modem used to send SMS to containing the information
5- KANNEL as SMS gateway
6- Captcha code software for prevention of BRUTE force attack, Make sure to install it in /var/www/reg/securimage, test it to make sure its showing images properly.

SCRIPTS:

Following PHP page and scripts should be copied to /var/www/reg folder [for ubuntu]

user.php [User Input Registration Form]
reg-display.php [Displays the User Input Result and execute the Script which executes the action]
reg.sh [main script that executes the action based on supplied information by reg-display.sh]
