One Voucher Per Device

Derelict

That would be a feature request.

Gertjan

Yup - that's what I proposed earlier in this thread - a day or so ago.
But : I have some code to play with that does just what @ajmaltms wants.

Derelict

Then that would be a pull request for that feature request :)

ajmaltms

@Gertjan yes..Voucher being used ones not usable for a next (concurrent) login..is it possible ?

Gertjan

@Derelict well, maybe I should write it out again .... I'll have a try.

He we go : the GUI part first :

@ajmaltms :
This looks good for you :

Btw : writing this up will take some time for me.
I'm writing this on a "live" system, and I'm not using Vouchers, but FreeRadius.

Derelict

This is not the forum for feature and pull requests.

https://redmine.pfsense.org/
https://github.com/pfsense/pfsense/

Gertjan

Don't worry, won't publish any PHP stuff here.
Just want to be sure I'm writing something useful.

When done and tested, I'll locate a feature request if one exists, and add my implementation as a pull request / review.

Derelict

No problem posting it. It's just that it probably won't get looked at by the right people unless it is put in the right places.

ajmaltms

@Gertjan which version is this ? i am using 2.4.4 i cant see that 3 options in my version...

Gertjan

I already went through the Forum => Redmine => Github phase twice, I guess.

@ajmaltms :
I'm using the same version as you. pfSense 2.4.4p2

I just have edited the code on my own pfSense setup.

Does the image looks good to you ?
As @Derelict stated, there is a whole procedure to respect when one want to change the 'official' code.
As said, this will take some time.

ajmaltms

@Gertjan yes..thats what i want...first login..

Gertjan

Good !

I'll post back here when I have a Feature request.
Attached to the feature request I'll be posting a pull request. At that moment, with the System_Patches package you can then retrieve the proposed pull request into your own pfSense to test drive the new code.
Eventually, if the pull request gets granted - IF this happensbolded text, the feature will be build into al new pfSense version.
This will take time - as most attention goes to "2.5.0" these days.

Derelict

It is unclear how someone would just allow all concurrent logins there.

I agree.
"Disabled" isn't the correct description.

Gertjan

Derelict

@Gertjan that seems more clear.

Gertjan

@ajmaltms : could not 'chat' all this to you, there is a 1000 char limit - so here it is :

Ready for the first try ?
Before you start, throw out all connected users. People that were logged in using Vouchers, in your case, that aren’t expired yet will be able to reconnect afterwards.

Make backup copies of the two files that will get modified.
I advise you to use the console access, option 8.
And/or SFTP access is also advisable – FileZilla does that just fine – Note : use SFTP, NOT to be confused with FTP.

Make a backup copy of this file

cp /etc/inc/captiveportal.inc  /etc/inc/captiveportal.inc.original

Another file to make a copy from :

cp /usr/local/www/services_captiveportal.php /usr/local/www/services_captiveportal.php.original

Thus, now you have spare copies of the 2 files that will be changed.

Here we go:
This is the new /etc/inc/captiveportal.inc file:
https://pastebin.com/V6uWHNz5
This is the new /usr/local/www/services_captiveportal.php file.
https://pastebin.com/QLhNhgAW

When these two files are in place, visit the portal config page, check your “Concurrent user login” settings: check one option out of the 3. I guess it will be “First” for you ^^ (see image above).

If there are any troubles, just copy your backup files back in place, like this (copy – paste these 2 commands will do that ) :

cp /usr/local/www/services_captiveportal.php.original /usr/local/www/services_captiveportal.php
cp /etc/inc/captiveportal.inc.original /etc/inc/captiveportal.inc

You’ll be seeing messages in your captive portal log file like:

.... CONCURRENT VOUCHER LOGIN - NOT ALLOWED - KEEPING OLD SESSION …

Which informs you that the same voucher was used a second time – the connection was refused.

I do not pretend that everything works perfect right now. This is just a first test.

I tested all 3 settings of “concurrent login” myself using Vouchers AND the classic Local manger user logins – both behave now as I want:

Multiple sessions per username / voucher
Last sessions per username / voucher
First sessions per username / voucher

The last one is the one you want to test.

Take your time to test – read the log file – send it over to me if question (use pastebin.org – not here in the forum)

Good luck.

@Gertjan not showing the three types of concurrent logins..but not working..still voucher can use same time..

Not showing but not working ?
Check this file /usr/local/www/services_captiveportal.php (in your pfSense)- for example lines 709 up until line 711 - you should see :

To assure you : the file I upload, is the file I'm using right now. "services_captiveportal.php" is part of the Captive portal settings GUI.
I tend to say : if you don't see anything change (only the "Concurrent user logins" item) you didn't copy the file.

edit : same thing for the file /etc/inc/captiveportal.inc - check line 2323. You should see this comment :

/* Implicit 'first' : refuse the new login - 'username' is already logged in */

@Gertjan sorry..showing 3 types..but not working
