I had the need to use RADIUS MAC auth with our UCRM billing system.

The billing system was *nearly* perfect but was lacking RADIUS.

I modified a github repo to do what I needed.

NOTE: You will need a custom 'service' attribute in UCRM for 'devicemac' to make this work.

I recently had a customer of my WISP ask if we could give her a way to log when her employees are working remotely.  She doesn't have a huge infrastructure with sophisticated logging abilities.  She felt that her employees were claiming to work when they really weren't even logged in.

This is a two part script.  One part runs on the Mikrotik, the other as a PHP script running on their server in the office.

Part 1(a) "create a script called 'vpn-log' on the Mikrotik":

:local urlRoot "http://192.168.99.22:82/?users=";

:foreach i in=[/interface find where type="pptp-in"] do={ 
  :local pptpName [/interface get $i name];
  :local userName [:pick $pptpName ([:find $pptpName "-"]+1) [:find $pptpName ">"]];
  set urlRoot ($urlRoot.$userName.",");
}
/tool fetch url="$urlRoot" keep-result=no

Part 1(b) "create the schedule":

/system scheduler add interval=1m name="Run vpn-log" on-event="/system script run vpn-log" \
    policy=\
    ftp,reboot,read,write,policy,test,winbox,password,sniff,sensitive,api \
    start-time=startup

<?php
date_default_timezone_set('America/Chicago');

$string_data = file_get_contents("current_users_DONT_DELETE.txt");
$currentUsers = unserialize($string_data);

$userArr = explode(",", $_GET['users']);
file_put_contents("current_users_DONT_DELETE.txt", serialize($userArr));

foreach ($currentUsers as $currentUser) {
	if ($currentUser !== "") {
		if (!file_exists($currentUser)) {
			mkdir($currentUser, 0777, true);
		}
		if (!in_array($currentUser, $userArr)) {
			file_put_contents($currentUser."/".date("Y-m-d").".txt", $currentUser . " - Log Out ".date('h:i A')."\r\n", FILE_APPEND);
			echo $currentUser . " - Log Out ".date('h:i A')."<BR>";
		}
	}
}

foreach ($userArr as $user) {
	if ($user !== "") {
		if (!file_exists($user)) {
			mkdir($user, 0777, true);
		}
		if (!in_array($user, $currentUsers)) {
			file_put_contents($user."/".date("Y-m-d").".txt", $user . " - Log In ".date('h:i A')."\r\n", FILE_APPEND);
			echo $user . " - Log In ".date('h:i A')."\n";
		}
	}
}
