Just to share an old idea gathered in year 2008 …
Scenario:
Mikrotik is configured with User Manager.
playSMS with Kannel is already configured and working in separate box (Ubuntu)
Task:
- Renew expired users via sending Username and SCRATCH CODE to playSMS (Ubuntu Server)
- Renew expired users via sending SCRATCH CODE & verify the code with the user profile [later]
Requirements:
- Mikrotik with User Manager . SSH must be enabled (with public key to enable linux ssh connectivity to mikrotik without Password)

Remember, I took User Manager as an example and uses some low and un secure scripting method. The goal was to show you the capabilities and things we can do by combining various apps and cross platform OS to get our results. This is no way a perfect example, but I am sure it will give you some idea how things can be started : )
You can take this example , and you can generate you scratch card codes and store it in MYSQL DB and FREERADIUS, therefore you can then pull CODE from specific DB and act accordingly after receiving SMS. I am sharing just some thoughts : )
1- Renew expired users via sending SMS to playSMS (Ubuntu Server)
This one is a very basic task. It does not involve any code to profile match check.
In this method user send sms with his Username and the scratch CODE. Once the server will receive the sms, it will first check the USERNAME at mikrotik, if it found valid username, it will then check the CODE in local text files (in this example I created 3 files, 512k.txt 1mb.txt and 4mb.txt , script will check all of three files (infact *.txt files) and if it found the CODE, it will then ssh to mikrotik and re-activate the user account with the given code profile. if the code belongs to 512k, it will re-activate user with 512k profile, and if the code is from 1mb pacakge, it will re-activate the account with 1mb profile.
SMS with following format
REN zaib 123
Explanation:
REN is a keyword which SMS server will catch and consider it as renew command.
zaib is user id
123 is password
Pseudo Code:
Server receive SMS with username and code
Server will SSH into mikrotik and look for username
If valid username found then it proceed further, otherwise issue error INVALID USERNAME and EXIT
If valid username found, then script will pick the second variable (code) and will look for this variable in /temp/*.txt , if it found the CODE then proceed further, otherwise issue error INVALID CARD NUMBER
If valid CODE is found in text files, then script will SSH to mikrotik and will re-activate the user account according to the package (which was fetched from the text file) and also print LOG in the window. You can also create other functions too like Remove the SCRATCH code once used, email admin or user, etc etc
Here is the example:
First create text files with the Scratch codes
example
cat /temp/512k.txt
123
cat /temp/1mb.txt
555
cat /temp/4mb.txt
999
Make Command on playSMS Server
As showed in the image below … or read my previous guide on howto make custom commands in playSMS
https://aacable.wordpress.com/2015/05/08/fun-with-sms-management-system-playsms/
Create SCRIPT on SMS Server which will be executed after receiving SMS
Create following SCRIPT on SMS Server.
cat /temp/test.sh
#!/bin/bash
#set -x
##########################################
# Script to renew User Manager account via received SMS
# Version 1.0b
########################################
# Strip user name and code because playsms will consider both variables as one, therefore we have to strip it in file
echo $1 > /tmp/user-card
USR=`cat /tmp/user-card | awk {' print $1 '}`
CARD=`cat /tmp/user-card | awk {' print $2 '}`
# Login to Mikrotik with SSH and look for validity of username
validuser=`ssh admin@101.11.11.255 :put [/tool user-manager user get value-name=actual-profile number=$USR]`
# If valid username found then proceed
if [ -n "$validuser" ]; then
echo -e "User name - $1 - found with profile reported by Mikrotik = $validuser"
# Look for SCRATCH code, and if it found valid then proceed
# You can also create other functions too like Remove the SCRATCH code once it is used , IMPORTANT !
grep -r1 $CARD /temp/*.txt -q
if [ $? -eq 0 ]; then
grep -q -rl $CARD /temp/*.txt | sed 's/\///g' | sed 's/temp//g' |sed 's/\.//g' | sed 's/txt//g'
grep -rl $CARD /temp/*.txt | sed 's/\///g' | sed 's/temp//g' |sed 's/\.//g' | sed 's/txt//g' > /tmp/crd
VAR1=`cat /tmp/crd`
echo "Scratch CODE found in list = $VAR1"
# Login to mikrotik and re-activate or re-assign the profile to the user according to the package found in text files
ssh admin@101.11.11.255 :put [/tool user-manager user create-and-activate-profile user=$USR customer=admin profile=$VA$
ssh admin@101.11.11.255 [:log warning Account_REFREH_DONE_ID_IS_$USR]
# If card number is invalid, then issue error
else
/bin/echo "Invalid CARD Name!"
fi
else
# If username is invalid, then issue error
/bin/echo "Invalid User Name!"
fi
TESTING ….
Send an sms to the server with following code
ren zaib 123
As soon the server will receive the SMS with the word REN, it will start act as following …
