NEW Package: freeRADIUS 2.x

Auth with EAP (TLS + TTLS) with dynamic VLAN
(…)

I think you found this in the pfsense docs, right ?

It means that a Client which is connected with EAP-TLS or EAP-TTLS will be put in a specific VLAN which RADIUS tells it.
VLAN attributes can be sent from FreeRADIUS - that is working - but when using TLS or TTLS than we need to send the reply attribute tunneled. This can be configured via "FreeRADIUS -> EAP" on GUI.
In general this should work - but I could not test this till now.

Dynamic VLAN assignment for the NAS does mean that the NAS gets the VLAN attributes from the RADIUS server and than changes the state of the port on NAS. This must be supported by the NAS.

I hope this is what you asked !?

Thank you.
I set up a test environment.

Updates pkg v1.5.6:

Fixed: typos in description (interfaces, users, macs)
Fixed: syntax error in additional check-items (users,macs)
Added: GUI TLS support for LDAP

in freeradius2,

can i form groups and add users into groups and create groups rules? :D
and how to bind user to mac address?

@filip_pag:

in freeradius2,

can i form groups and add users into groups and create groups rules? :D

This isn't possible from GUI at the moment. And I don't know if groups can be build without any SQL database. In SQL you can create a group and put users into this group.

Then you can add the following as "Additional RADIUS Attributes on the TOP of this entry":

DEFAULT Group == "disabled", Auth-Type := Reject

DEFAULT Group == "disabled": matches all users in the group "disabled"
Auth-Type := Reject: sets auth-type to reject and so rejects all users in this group.
You can work with:

Fall-Through = yes

If other attributes should be assigned like VLAN and so on. But this isn't easy to handle from GUI so it would be perhaps easier to configure all attributes for every user.

@Nachtfalke

coming back to AD with PAP
for me it is only one thing to change against webgui:
/usr/local/etc/raddb/sites-enabled/default:

authenticate
{
Auth-Type LDAP {
ldap
}
}

I am not familar with AD or LDAP so perhaps it is possible for you to give the example - using the pfsense web GUI (Screenshot) or something else how you configured it for your domain :P
So that we know what you filled out for "Base DN" and so on ::)

PS: Which samba package do we need ? Which version ? Link to freebsd ftp ?
I am thinking about to make a possibility to install samba and configure it this was but not installing samba by default when installing freeradius2 package.

Hi Nachtfalke,

I am using the pfSense on an embedded device (ALIX board).
After system boot the file system (/) is mounted as read only.
When starting the freeradius server it reports following error mesages:

Jan 26 20:38:50 radiusd[53305]: /usr/local/etc/raddb/modules/counter[71]: Instantiation failed for module "daily"
Jan 26 20:38:50 radiusd[53305]: /usr/local/etc/raddb/modules/counter[71]: Instantiation failed for module "daily"
Jan 26 20:38:50 radiusd[53305]: rlm_counter: Failed to open file /usr/local/etc/raddb/db.daily: Read-only file system
Jan 26 20:38:50 radiusd[53305]: rlm_counter: Failed to open file /usr/local/etc/raddb/db.daily: Read-only file system

Do you think it is possible to locate these file within the /var/.. or /tmp/… folder.
These folders are RAM drives (/dev/md[0|1]) which are mounted as read-write after system boot.
Could you be so kind to locate also other runtime/temporal files in these folders?

Thanks a lot & best wishes

Hi Hermel,

I am not using an embedded device. Do you know if it is possible to installe pfsense embedded in a VM ?
If there is a way to virtualize this than I could spent some time on doing and testing this. Don't know how much work this will be.

The "db.daily" is a database and needs to be persistent after a reboot.

You can test and edit freeradius.inc starting at line 2544 - 2674:

/usr/local/pkg/freeradius.inc

original:

counter daily {
	filename = \${raddbdir}/db.daily
	key = User-Name
	count-attribute = Acct-Session-Time
	reset = daily
	counter-name = Daily-Session-Time
	check-name = Max-Daily-Session
	reply-name = Session-Timeout
	cache-size = 5000
}

counter weekly {
	filename = \${raddbdir}/db.weekly
	key = User-Name
	count-attribute = Acct-Session-Time
	reset = weekly
	counter-name = Weekly-Session-Time
	check-name = Max-Weekly-Session
	reply-name = Session-Timeout
	cache-size = 5000
}

counter monthly {
	filename = \${raddbdir}/db.monthly

	reset = monthly
	counter-name = Monthly-Session-Time
	check-name = Max-Monthly-Session
	reply-name = Session-Timeout
	cache-size = 5000
}

counter forever {
	filename = \${raddbdir}/db.forever
	key = User-Name
	count-attribute = Acct-Session-Time
	reset = never
	counter-name = Forever-Session-Time
	check-name = Max-Forever-Session
	reply-name = Session-Timeout
	cache-size = 5000
}

counter maxdailyupload {
	filename = \${raddbdir}/db.maxdailyupload
	key = User-Name
	count-attribute = Acct-Input-Octets
	reset = daily
	counter-name = Daily-Input-Octets

	counter-name = Daily-Output-Octets
	check-name = Max-Daily-Output
	reply-name = Acct-Output-Octets
	cache-size = 5000
}

counter maxweeklyupload {
	filename = \${raddbdir}/db.maxweeklyupload
	key = User-Name
	count-attribute = Acct-Input-Octets
	reset = weekly
	counter-name = Weekly-Input-Octets
	check-name = Max-Weekly-Input
	reply-name = Acct-Input-Octets

}

counter maxweeklydownload {

	key = User-Name
	count-attribute = Acct-Output-Octets
	reset = weekly
	counter-name = Weekly-Output-Octets
	check-name = Max-Weekly-Output
	reply-name = Acct-Output-Octets
	cache-size = 5000
}

counter maxmonthlyupload {
	filename = \${raddbdir}/db.maxmonthlyupload
	key = User-Name
	count-attribute = Acct-Input-Octets
	reset = monthly
	counter-name = Monthly-Input-Octets
	check-name = Max-Monthly-Input
	reply-name = Acct-Input-Octets
	cache-size = 5000
}

counter maxmonthlydownload {

	key = User-Name
	count-attribute = Acct-Output-Octets
	reset = monthly
	counter-name = Monthly-Output-Octets
	check-name = Max-Monthly-Output
	reply-name = Acct-Output-Octets
	cache-size = 5000
}

counter maxupload {
	filename = \${raddbdir}/db.maxforeverupload
	key = User-Name
	count-attribute = Acct-Input-Octets
	reset = never
	counter-name = Forever-Input-Octets
	check-name = Max-Forever-Input

	counter-name = Forever-Output-Octets
	check-name = Max-Forever-Output
	reply-name = Acct-Output-Octets
	cache-size = 5000
}

this will save the db.daily and the other dbs in /tmp

i want to limit bandwith for one user, I enter bandwith limit(upload&downlaod) for
user account but it isnt working, I tried also for MAC address but it dont work, do I
have to enable some rule or?

Hermel

Hi Nachtfalke,

I have tested the changes you proposed and after a reboot, the server has the status "running"

But root (/) is not mounted as read only.
I currently do not know why.
The only log entries which could relate on this topic are:

Jan 27 00:55:32 php: : freeRADIUS: Switched to pfSense Cert-Manager. Creating new DH and random file in /usr/local/etc/raddb/certs
Jan 27 00:55:29 php: : FreeRADIUS: Restoring the original file from /usr/local/etc/raddb/policy.conf.backup and /usr/local/etc/raddb/files.backup
Jan 27 00:55:28 php: : FreeRADIUS: Restoring the original file from /usr/local/etc/raddb/policy.conf.backup and /usr/local/etc/raddb/files.backup

But today it is too late to make a more detailed analysis and at the weekend I will not be at home, thus I have to shift this topic to next week.

However finally I would like to reply to your comments/questions:

I am not using an embedded device. Do you know if it is possible to installe pfsense embedded in a VM ?
So far as I know this is not possible.

The "db.daily" is a database and needs to be persistent after a reboot.
Well if my understanding is corret, then the files have to be stored at shutdown and restored at boot.
This may be quite complex … I am open minded to support you at the development - also if I do not have too much time.

Have a good time

Updates pkg v1.5.6:

fixed: a bug when the shortname of a NAS contains whitespace(s).

Hi Hermel,

Jan 27 00:55:32 	php: : freeRADIUS: Switched to pfSense Cert-Manager. Creating new DH and random file in /usr/local/etc/raddb/certs

This error ist related on the certificates which are located in /usr/local/etc/raddb/certs/
So it wouldn't be possible to create and import new certs to freeradius2 because the directory is write-protected. We only need write access if we store there the new certs after this it is ok for "read-only". I think I can fix this idependent from pfsense version (embedded or install).

Jan 27 00:55:29 	php: : FreeRADIUS: Restoring the original file from /usr/local/etc/raddb/policy.conf.backup and /usr/local/etc/raddb/files.backup
Jan 27 00:55:28 	php: : FreeRADIUS: Restoring the original file from /usr/local/etc/raddb/policy.conf.backup and /usr/local/etc/raddb/files.backup

This error is related to the fact that you can switch between the "normal" 802.1X auth (default) or the possibility to enable "Plain-MAC-Auth" in "Settings". I made this because I do not know if there are site-effects when enabling this but as far as I can see that there is no problem. So there shouldn't be a problem for embedded devices.

On weekend I will give thought to this and try to find a solution.

But the basic features of freeradius2 should work so give it some more tests if you found time and post problems.

Bandwidth-Limit needs - as most of the settings - support of your NAS. The NAS can be your switch, access-point or pfSense Captive Portal.
The attributes the NAS must understand are the following:

WISPr-Bandwidth-Max-Up
WISPr-Bandwidth-Max-Down

Check your NAS documentation or post the NAS then we perhaps can find out how to handle this.

When using Captive Portal on pfSense then take a look here:
http://doc.pfsense.org/index.php/FreeRADIUS_2.x_package#Amount_of_Bandwidth

The attributes in my documentation are only to show which attributes are needed for this to work. If the NAS does not support these attributes than bandwidth limit will not work. But Captive Portal can do this.

What you have to do is:

Go to:
SERVICES => CAPTIVE PORTAL
scroll down and enable "Per-user bandwidth restriction"
leave bothe fields empty (so all users have unlimited bandwidth).

Go to:
SERVICES => FreeRADIUS => USERS
there you create all users you want. For the one user you want to limit its bandwidth scroll down to:
"Maximum Download Bandwidth" and "Maximum Upload Bandwidth".
There you have to enter the bandwidth limit for the user.
Important: You have to enter "BIT per second"….8Bit = 1Byte and 1024Byte = 1Kilobyte

After you have changed bandwidth limits for a user AND this user is connected while you changed the settings than the will not take effect. So make sure that you disconnect the user after you made changes so that the user needs to reconnect.

PS: Not sure if it works 100% because there seems to be a bug in CP and/or ipfw which counts sometimes different. For example when using "Amount of traffic" then if in real 1MB passes CP than CP sends back 6MB to the RADIUS server.

So do some tests and try to find out how it works.

Hi Nachtfalke,

I've received a patch from freeradius maintainer to compile it with heimdal instead of krb5.

I'll test compiling it but as usual I need help on testing.

Of course I'll do that :)

But help me - I forgot it - what will heimdal improve/change instead of using kerberos ? ???

@Nachtfalke:

Some pages ago, to get kerberos working, we need to force heimdal(A popular BSD-licensed implementation of Kerberos 5) package install.
