freeRadius / Unifi AP / EAP-TTLS ?

furom

Hi,

I am trying to setup the above, freeRadius using EAP.TTLS with my Unifi AP.

After initial configuration I added a new "Authentication Server" from System/User Manager.
When I after that have created a user in freeRadius, I can't validate that using Diagnostics / Authentication, it just refuse to work! I have done it, redone, started over etc. No matter what I have tried...

This certainly is not, or should not be, as hard as it has proven to be. What can I try to resolve this please? I must clearly miss a step somewhere...?

Edit: Just noticed this in the log, not much more than I experienced though;

May 14 18:01:27 	php-fpm 	280 	/diag_authentication.php: Error during RADIUS authentication : Operation timed out

Thanks

@furom Have you added the AP into FreeRADIUS NAS/Clients page ?

A radsniff-x from a console may point to the problem.

Thanks! I keep forgetting about that! A lot going on right now... I will see if that may give any new leads! :)

I am trying it now, and I have rarely seen less traffic... :)

But I'm thinking, as freeRadius isn't really configured yet, will there be anything for it to find? From the name I'd suppose it only shows radius related traffic, right?

The step I have issues with is to be used with radius, but really a function of basic pfSense as I understands it..?

I tried to uninstall everything, including all settings, but even when unchecking the setting in freeRadius v0.15.10

Save settings after deletion
"If enabled, the settings will be preserved across package reinstalls. Important: If disabled, all settings will be wiped on package uninstall/reinstall/upgrade."

steps;

unchecked above setting in freeradius/settings - Saved
uninstalled the package using package manager - rebooted
installed freeradius
created a Authentication server for Radius
... discovered all my previous settings was still there...

I can't seem to catch a break with this lately. Can I ssh in and wipe settings there, or are they scattered through out?

I am usually so impressed with Netgate and pfSense, but this is kinda getting to me a little. It just don't feel that robust right now with all things considered.

Maybe a good set of sectioned backups for all I think I need and a hard reset is the answer... But really don't feel much for it tbh. Wonder if other firewalls have similar issues... :/

@furom Did you try running radsniff -x from the console ?

Not just that, no. Perhaps I overthink it, but shouldn't I specify an interface? I will give radsniff -x a go as soon as I get SSH setup again... :)

@furom I run eap-tls with one of my ssids on unifi, and use freerad on pfsense as auth.. I don't recall any issues with setting it up.. I had it off for a while when my company locked down my phone and prevented me from installing the profile on my phone with the certs. But recently re-enabled it and not having any problems.. if you want I could post my configurations up.

@furom If you don’t see any thing output from radsniff -x it’s highly likely that the ap isn’t set up correctly.

I would really appreciate that, thanks!

Well, either that, agreed, or something more intricate. As I said before, I set up a user, and am unable to validate it in Diagnostics, no matter how simple secrets & passwords... I don't think a system can be haunted, but sometimes wonder... well, I hope not.

johnpoz

@furom here you go

Config from pfsense freerad, settings for my ssid, and the freerad profile that tells the unifi where to go.. And then at the end you can see my phone authing..

furom

@johnpoz OMG. That is so helpful! Much appreciated!! It's a bit late to start with that right now, but will try it out tomorrow! :)

johnpoz

@furom if you need any help - just ask... I do like using a secure eap like eap-tls for my trusted devices on my trust wifi vlan.. I just wish iot devices supported wpa enterprise ;)

edit:
keep in mind you do need certs for these users - and getting the profile into say ios can be problematic - it doesn't like no password, etc. so I believe I run it through openssl to create the bundle, etc.

edit2: just noticed using old cert for my old phone ;) I now have a 13, but its using my old XR cert heheh

Good points, I do have the certs I need at least, and know they're good. So a starting point at least, and with all this great help I can't think of what could go south... :)

Hi there :) So much at the sam time, but now finally time for EAP-TLS, after all trouble I'm actually a little hesitant to even try, but I do want it too...

Did you follow any special path or just mended it together? One thing that I see others do, is creating a new separate "Authentication server" for radius, I can't tell if you did so too. This step was one that always failed before...

johnpoz

@furom you do need too point to freerad on your unifi setup.. Not even sure if you can fire up multiple configs for freerad on pfsense?

Multiple configs? But yes, the Unifi part is clear I think. What is a little unclear is if this is needed or not?

furom

@furom This is well, embarrassing. I have done to the letter almost what you have. All the options the same etc.
But... same step relentlessly fails; verifying the user I create for radius... I have tried with a password I would like, with a very simple one, and it just won't work.
Secret is copy/pasted, so is most other duplicated stuff.
I will let it be now as you perhaps may have an idea where to look...

I finally ran

[root@netgate ~]# radsniff -x
Logging all events
Defaulting to capture on all interfaces

which did not show one single thing, so at least it is a big mistake somewhere...

Thanks :)

@furom well if you don't send any traffic why do you think radsniff would show anything?

Here is my phone coming in from trying to talk one of my AP on 192.168.2.2, do you have a firewall rule setup to allow your AP ips to talk to freerad on port 1812?

radsniff would not have anything to do with your setup of freerad, but if stuff is trying to auth to you. You would need to have firewall rules to allow that traffic - sorry if I left that off, but pretty basic that if you have a service listening on 1812, that stuff is going to talk to - your firewall rules would have to allow that.

As to setting up authentication server in pfsense - why would that have anything to do with freerad authing users for other devices.. No you don't need to setup anything there.

I set up radsniff and then tried to diag/auth, but didn't exactly show much.

Ok. And yes, of course I understand I need a firewall rule,

This should be permissive enough... I bet it's just a tiny thingy somewhere... I have to go over everything again...
