[HOWTO] Captive portal + FreeRADIUS + local MySQL user friendly single step

deajan

@abebraham:

is it possible to use a node.js file for the captive portal? Or using mongodb?

MySQL is used because of the FreeRADIUS authentication.
You may adapt the php script to whatever database your RADIUS server uses.

@deajan:

@nhimcoi30889 Sorry to hear. But the error doesn't suggest the problem comes from the captiveportal files I've written.
What pfSense version are you running ?
Can you reproduce the error on a VM ?

Hi deajan,
my issue resolved by rollback pfsense ver 2.2.6 (issue on ver >= 2.3 )
i have a question more. i found this on captiveportal-config.php file

$confirmationCode = "0000";

If i want this code generate via mysql ?
For example, i gen about 100 codes map with 100 email and storage on database. When user input their email and confirmationCode after they access internet

deajan

@nhimcoi30889 This captive portal isn't supposed to work that way. It's an "no account setup" portal page.

If you want to use it the way you describe, you should create the radius accounts you want with the confirmation code as password, and remove the part where the radius account is created from the main CP file.

Hi Deajan,
I can to create account on Radius with format email address ?
For example : test@abc.com

deajan

@nhimcoi30889 Sorry but your sentence makes no sense to me. If your question was if radius supports emails as usernames, the answer is yes.

HI deajan,
today i just upgrade from 2.2.6 to 2.3.1 Release
After upgraded, i start mysql againt but show error :

[2.3.1-RELEASE][admin@pfSense.it.mt]/root: service mysql-server.sh start
Starting mysql.
Bad -c option
/usr/local/etc/rc.d/mysql-server.sh: WARNING: failed to start mysql

Can u help me?

deajan

Upgrades in 2.2.X are destructive for MySQL installation because they basically reinstalls a full OS.
Only 2.3.X upgrade series won't destroy anything because they work fine grained.

In order to get things working again, you have to uninstall and reinstall mysql. Keep in mind that directions to install mysql for 2.3.x aren't the same as for 2.2.x.

Hi Deajan.
Firstly a big thank for this great howto. Detailed and comprehensive.
Now, I apologize, I'm a newbee about pfSense (although an experienced Linux/PHP/DB/ecc. programmer), so my question might be trivial.
The network I'm trying to setup with your captive portal feature has a router (Zyxel) with REDIUS support. The router is also configured to act as DHCP server for my local network. Actually my pfSense machine/installation will be used ONLY for RADIUS/CaptivePortal authentication. In other words, my pfSense installation is configured in "appliance" mode, i.e. with the only one eth interface (WAN) enabled. I've configured the router to assign a static IP to my pfSense server.
The point now is this. When I create a CP zone in the WebConfigurator, at the bottom of the page I read the following hint:

Don't forget to enable the DHCP server on the captive portal interface! Make sure that the default/maximum DHCP lease time is higher than the hard timeout entered on this page. Also, the DNS Forwarder or Resolver must be enabled for DNS lookups by unauthenticated clients to work.

What about the DHCP server on the CP interface? Do I need to disable the router's DHCP server, in order to have pfSense assign all the mess, or is there another way to configure the DNS resolver?
Thanks again for the great howto and any suggestion you'll give.

deajan

Sorry for the late reply.
As long as the DNS is pfSense, I think you can use whatever DHCP server you like.

@nhimcoi30889

I'm pretty sure that you have two instances of mysql running. Check with ps aux.

Hi deajan,

First thank you very much for this perfect HOWTO.

But I got a problem when i import the admin.sql script. Please have a look below:

 mysql radius < admin.sql
ERROR 1064 (42000) at line 31: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'PRIVIELGES' at line 1

Do you have any idea how to fix it? I am running a brand new pfsense 2.3 on a PC. Thank you in advance.

deajan

There was a typo in admin.sql, should read PRIVILEGES and not PRIVIELGES.
Corrected on github. You may redownload the latest archive at https://github.com/deajan/pfSense-cp-auth-onestep/archive/master.zip

Hello deajan,

First thank you a lot for your work, the system works great !

I try to use your template only with the "room number" field to log in on the portal.

I successfully disable the others fields (familyName, surName, emailAddress and newsletter) but when i validate the form, I've a blank page.

However, I pass the portal and I can access to the web but the result is not very clean

Could you please explain me which modifications I have to make in ozy-captive.php and perhaps in captiveportal-config.php .

Thanks in advance !

deajan

Hello xAm56,

As far as I remember, the username is a combination of emailAdress and roomNumber and password is a combination of familyName and surName, in order to get some degree of randomness.
Basically, only using room number would mean that Radius records would not be unique.

I'll have a to push an update until monday which adds the language parameter in the url.
I'll try to check your usecase in the same time.

Regards,
Orsiris.
