After a bit of work, I was able to solve it by running a php script in the preacct process.

I added the external program with exec:

exec 1stlogin {

wait = yes
                program = "/usr/bin/php /root/1stlogin.php %{User-Name} %{Calling-Station-Id}"
                input_pairs = request
}

Then in the preacct session I added
1stlogin

The script itself as follows:

<?php
$link = mysql_connect('localhost', 'root', 'xxxxxx');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
mysql_select_db('radius');
$result=mysql_query("SELECT * FROM radacct WHERE `UserName`='$argv[1]' order by Username limit 1");
$val = mysql_num_rows($result);
if ($val > 0)  {
printf ("Not first auth"); 
}
else {
mysql_query("INSERT into radcheck (UserName, Attribute, op, Value) values ('$argv[1]', 'Calling-Station-Id', '==', '$argv[2]')");
}

?>


I rarely write any php, so any improvement in the code is highly appreciated. Do I need to return anything to freeradius in case of an error or something?

Cheers,
Kledi

Hello,

I need a way to set the Calling-Station-Id attribute automatically for each user after the first authorization request. In this way the user will be allowed to authorize only from that mac address in the future.

I am using freeradius 1.1.7 with mysql. I do not have the expertise to write a new module, but I believe the way to do it is:

- User tries to authorize and sends username/password/calling-station-id
- Radius verifies username/password (calling-station-id is not yet set)
- Check if a user has ever authorized, through a query on the radacct table. If no rows exist for the specific username then its first login
- insert a row containing the calling-station-id for the specific user in the radcheck table.

Is there a way to do this by configuring freeradius, or do I have to submit it as a request for a feature?

Thank you,
K

you can use modules checkval to make calling-station-id check.
But for add calling-station-id on first login, you need more scripts to add it.
you may use unlang. for me i use pppoe-server as nas. i use php to add it after first login.
