Hi Deajan, Thank you for sharing your work.
My mistake I messed up mysql password during 'secure installation'.

How can I reset it to carry on with your [How To]

Thank you again.

@krotin google is your friend http://www.pastbedti.me/2008/11/resetrecover-mysql-root-password-in-freebsd/

Thank you, I know google is my friend but i'm not trusting every source granted i'm new to freebsd.

At least I know I can safely follow those instructions with your recommendations.

Thank you for your kindness Sir.

Krotin.

Hello. Is your work runnig both 32bit and 64bit platforms? Coz i noticed that some installation commands end with "amd64". So it means that installation package is for 64bit platform? When i wanna use 32bit platform do i have to use 32bit installion package?

Hi, I try to instal but when i try to instal mysql56-server, or mysql57-server go in conflict with the library libevent2-2.0.22_1 and libevent-2.1.8 in 64 bit version.

To no one else does the same?

mastrus

I resolved the situation by using the development version 2.3.4-DEVELOPMENT (amd64), that does'nt have library conflict.

Also I have a problem with freeradius version 1.7.8 that don't allow to input into the interface the ip 127.0.0.1 so after installing freeradius I modificate the file /usr/local/pkg/freeradius.inc at line 4384 from

if (!is_ipaddr_configured($post['varinterfaceip'])) {

to

if (!is_ipaddr_configured($post['varinterfaceip']) && $post['varinterfaceip'] != "127.0.0.1") {

I found the information in tha post https://forum.pfsense.org/index.php?topic=127875.0

the last problem with freeradius version 1.7.8 is that need in the EAP section on "certificates for tls" all the voice with a hit

in the first you need to create a CA certificate, in the second a revacation list for the certificate and in the thir a ssl server certificate

Thanks for sharing. I have to setup a new pfSense test platform these days because of some changes I recently made on the mysql code. I'll update the howto then.

You have not updated this documentation page at this time

I'm aware of that :) Still have to redo the whole howto on a recent pfSense build in order to rewrite it properly and address new issues, but as always, time is a b****, and I was more eager to rewrite the portal itself for security reasons than the manual.

Hi deajan, thanks a lot for this project.
Is it possible to use this Captive Portal for self registration on a unencrypted WLAN SSID with username and password, and use these credentials to authenticate on a encrypted WPA2 Enterprise SSID (with PEAP authentification or something like that)?

Hi,

I'm not really sure what's your usecase here, but if I understand right, you want users to self sign in on a first wireless network, then have them connect on the secured wireless network with the credentials they created earlier.
You would have to modify the code of the captive portal to add a password option (let's say instead of the room number or so).
Then you'd need to add the pfSense FreeRADIUS server to your WPA2 setup.
Could you elaborate a bit please ?

That's exactly what I want to implement.
I've got three LANCOM L-322agn Access Points, one LANCOM WLC-4006+ Controller and a pfSense Setup. This will be used for a public WLAN in a small industrial area. The idea is to provide these two SSIDs with the access points at the same time. I do not want to use a "normal" WPA with pre shared key to provide more security when using the WLAN without VPN. I Think 802.1x/EAP with MSCHAPv2 or somethink like that would be better. What would be the best way to do that with your Captive portal solution? My PHP and JavaScript knowledge is unfortunately limited :-\

Is there any way with this setup to limit the amount of data one user can use at one time? say i want user bob to only have a max download limit of 1 GB for the duration of his time at the hotel?

deajan

Especially for Bob ? or All Bobs ? :)

@deajan:

All Bobs lets say have a max download each of 1gb and all daves have max download of 500mbs

i have tried this
INSERT INTO radcheck (id, username, attribute, op, value)VALUES (NULL, 'bob', 'Acct-Output-Octets', ':<', '5242880');
INSERT INTO radcheck (id, username, attribute, op, value)VALUES (NULL, 'bob', 'Acct-Output-Octets', ':=', '5242880');
INSERT INTO radcheck (id, username, attribute, op, value)VALUES (NULL, 'bob', 'Acct-Output-Octets', ':!=', '5242880');
INSERT INTO radcheck (id, username, attribute, op, value)VALUES (NULL, 'test3', 'Max-forever-Octets', ':=', '5242880');

I guess im not supposed to do this as Freenas documentation says i cant use < as a operator for check…. any idear ?

deajan

You should check FreeRADIUS docu for this: https://wiki.freeradius.org/modules/Rlm_sqlcounter
Also, check that rlm_sqlcounter module is present in pfSense :)

Hi Deajan!
I am trying to implement your solution at a hotel.
So also Freeradius and MySQL are working fine, but the Captive Portal didn't.
I tried twice, building two VMs in Virtual Box and pfSense 2.3 (last stable version). The first machine, after fill the form and accept the terms of use, when I click on confirm button appears 404 error. After hours and hours looking for what could be happening I gave up and decided to start over again, building a new VM.
In the second VM I took the same case: MySql and Freeradius are working fine, but now when I click on confirm button appears a blank page without any error. In browser address bar appears the Server IP + /$ symbol.
Can you advice me to find a solution? I had past entire Sunday doing this!
My best regards!
Giovani

PS: I found in my downloads a 2.2 pfSense version. I was thougthing in do a downgrade.

(The captive portal) web server log didn't mention what happened ??
Are you using the default built-in captive portal page ?

deajan

@giovani.junior: Don't use the integrated view button as behavior changed in 2.3.2+, see https://forum.pfsense.org/index.php?topic=132106.0
Also, have you configured the redirection address for the CP ?
