NEW Package: freeRADIUS 2.x

Nachtfalke

(…)
Personally I've tried setting using the account expiration (at a specific date) feature in Freeradius2 and it doesn't seem to work. If I put a date in the past (using the format "Jan 01 2012") the account seems to still be valid. If I put the date of tomorrow and wait until the next day the account is still valid.

I would really like to make this feature work to create guest account valid for a few days. Anyone using it? According to the Freeradius2 package wiki page this feature should work.
(...)

This feature is not described on freeradius2 wiki page. Here is a description of how it should work:
http://lists.freeradius.org/pipermail/freeradius-users/2009-December/043702.html
Check the users file if the syntax is correct after you entered that in the GUI.

Not sure if it will work if you set a "Session-Timeout" on freeradius GUI, too. It could be possible that "Session-Timeout" and "Expiration" will not work correctly when used together because "Expiration" sends a Session-Timeout to CP and "Session-Timeout" will be, too. This could be a conflict.

But to make sure that CP understands Session-Timeout you have to enbale it on CP page.

 	Use RADIUS Session-Timeout attributes
When this is enabled, clients will be disconnected after the amount of time retrieved from the RADIUS Session-Timeout attribute.

Hi,
I've been looking into the freeradius and the XMLRPC part of it
I ran into certain issues because I'm trying to replicate with mobile networks that might be within internet range or not (trucks and boats…)

during my tests the XMLRPC seems to hang when the device it is trying to replicate to does not responds (not sure what is the time out period if any)

I looked at the code... but with my limited knowledge what I figure out I could do is actually to select the destination servers before I do the changes
to have that ability I modified the package the following way.

in
/usr/local/pkg/freeradiussync.xml
I added a check box for each destination server so we can choose which one we want to syn at that moment

<field><fielddescr>Destination Server</fielddescr>
<fieldname>none</fieldname>
<type>rowhelper</type>
<rowhelper><rowhelperfield><fieldname>varsyncdestinenable</fieldname>
<type>checkbox</type></rowhelperfield>
<rowhelperfield><fielddescr>GUI Protocol</fielddescr>
<fieldname>varsyncprotocol</fieldname>
<description>http or https]]></description>
<type>select</type>
<default_value>HTTP</default_value>
<options><option><name>HTTP</name><value>http</value></option>
<option><name>HTTPS</name><value>https</value></option></options></rowhelperfield>
<rowhelperfield><fielddescr>GUI IP-Address</fielddescr>
<fieldname>varsyncipaddress</fieldname>

<type>input</type>
<size>15</size></rowhelperfield>
<rowhelperfield><fielddescr>GUI Port</fielddescr>
<fieldname>varsyncport</fieldname>

<type>input</type>
<size>3</size></rowhelperfield>
<rowhelperfield><fielddescr>GUI Admin Password</fielddescr>
<fieldname>varsyncpassword</fieldname>

<type>password</type>
<size>20</size></rowhelperfield></rowhelper></field>

–---------------------------------------------
in
/usr/local/pkg/freeradius.inc

I updated freeradius_sync_on_changes() so it would look at the check box and execute the line if it is enable for that server

function freeradius_sync_on_changes() {
global $config, $g;
$varsyncenablexmlrpc = $config['installedpackages']['freeradiussync']['config'][0]['varsyncenablexmlrpc'];

// if checkbox is NOT checked do nothing
if(!$varsyncenablexmlrpc) {
return;
}

log_error("FreeRADIUS: Starting XMLRPC process (freeradius_do_xmlrpc_sync).");

// if checkbox is checked get IP and password of the destination hosts
foreach ($config['installedpackages']['freeradiussync']['config'] as $rs ){
foreach($rs['row'] as $sh){
// if checkbox is NOT checked do nothing
if($sh['varsyncdestinenable']) {
$varsyncprotocol = $sh['varsyncprotocol'];
$sync_to_ip = $sh['varsyncipaddress'];
$password = $sh['varsyncpassword'];
$varsyncport = $sh['varsyncport'];
if($password && $sync_to_ip && $varsyncport && $varsyncprotocol)
freeradius_do_xmlrpc_sync($sync_to_ip, $password, $varsyncport, $varsyncprotocol);
}
}
}
log_error("FreeRADIUS: Finished XMLRPC process (freeradius_do_xmlrpc_sync).");
}
–-------------------------------------------

Can anyone validate that these changes make sense and that I'm not breaking something else by doing this?
also if helpful for anybody else can it be committed to future releases of the package?

Cheers,

marcelloc

Did you tested it? For me it looks fine.

Nachtfalke

Not sure if it makes sense to select the hosts you want to sync. If you do not want to sync a host just delete it. Why using an extra checkbox for that ?
I do not think this is really usefull because in general you want to have the same content everywhere.

Perhaps another/better option could be to make the timeout editable. I am not familar with XMLRPC code but it seems to be at 150s (2m30s).
Try to change the value on this lines in "freeradius.inc" to al value of - lets say - 20s

The lines

Marcello, can you confirm that these are the values for the XMLRPC timeout ?

marcelloc

@Nachtfalke:

Sometime admin wants just to disable sync host instead of delete it. sarg schedule tab has this checkbox too.

@Nachtfalke:

Following code comment, it looks like a timeout

/* send our XMLRPC message and timeout after 150 seconds */
		$resp = $cli->send($msg, "150");

Hi marcelloc and Nachtfalke,

thanks for the follow up,
I'm currently testing and so far so good
I think adjusting the timeout will meet my needs in a better way
I still like the idea of having the option of disabling a server without having to delete it as in my case I'm managing about 7 mobile networks that are installed in boats and usually go out of range
hence there is a big chance that at least four or of them will not be available when i do a new entry on the radius server (that is where the time out helps)
but sometimes some of this boats are down for maintenance for a few month and in that case I would like to stop the replication to them without having to delete the entry (that is where the check box for the Destination server helps)

So far I have check the backup file for the pfsense settings and the entry for the check box is there :)
I also added an extra line to the function freeradius_sync_on_changes() so it will log the servers that are disable
(not a big deal, but it is nice to double check that it is actually doing what it is supposed to be doing)

–-----------------------------------------------------------------------------------------------------------
function freeradius_sync_on_changes() {
global $config, $g;
$varsyncenablexmlrpc = $config['installedpackages']['freeradiussync']['config'][0]['varsyncenablexmlrpc'];

// if checkbox is NOT checked do nothing
if(!$varsyncenablexmlrpc) {
return;
}

log_error("FreeRADIUS: Starting XMLRPC process (freeradius_do_xmlrpc_sync).");

// if checkbox is checked get IP and password of the destination hosts
foreach ($config['installedpackages']['freeradiussync']['config'] as $rs ){
foreach($rs['row'] as $sh){
// if checkbox is NOT checked do nothing
if($sh['varsyncdestinenable']) {
$varsyncprotocol = $sh['varsyncprotocol'];
$sync_to_ip = $sh['varsyncipaddress'];
$password = $sh['varsyncpassword'];
$varsyncport = $sh['varsyncport'];
if($password && $sync_to_ip && $varsyncport && $varsyncprotocol)
freeradius_do_xmlrpc_sync($sync_to_ip, $password, $varsyncport, $varsyncprotocol);
}
else {
log_error("FreeRADIUS: Sync with {$sh['varsyncipaddress']} is disable");
}
}
}
log_error("FreeRADIUS: Finished XMLRPC process (freeradius_do_xmlrpc_sync).");
}

Hi itbit,
Hi marcello,

I am going to be on holliday the next two weeks. I don't want to add some code which could (but probably will not) cause a problem with the package. If you are able to do some tests please feel free to add these changes to the package on github. I think the both options - change the timeout value and to disable/enable temporarily some hosts will be a good improvement.

Thanks for your help!

itbit

Hi Nachtfalke and Marcelloc,

I have updated both freeradius.inc and freeradiussync.xml to allow the modification of the default XMLRPC timeout from the GUI
I also added the checkbox option for selecting to which servers we want to sync

both files have been attached to this post.

I also tried (but failed) to include an option to specify the user name for the account that will sync because in some of my Pfesnses I changed the default username from 'admin' to something else
but it works out that 'admin' is hardcoded in several places including xmlrpc.inc…

hopefully this all looks right to you, so far I have tested and is working as expected.

Cheers,

freeradiussync.xml.txt

itbit,

push it via github.

It will be easier to check changes and commit on current code.

Well… It took me a bit to figure it out
but I think I got it.
i proposed the changes at

Updates pkg v1.6.6_4:

Added: Possibility to edit the timeout when doing an XMLRPC sync between different RADIUS servers. If one RADIUS Server does not respond the main pfsense does not respond until the default timeout of 150s is over.
Added: Possibility to endable/disable a host when doing an XMLRPC sync. This allows you to add all destination hosts you want to sync this but if one is down or you do not want to sync the changes to this host you can disable this host for sync.

Thank you itbit for adding this code and these options to the package. :-)

Known bugs:

When using "stop/start accounting on CP then "Amount of Time/Amount of Traffic" isn't working correctly.
http://redmine.pfsense.org/issues/2164
When using CP + RADIUS + Vouchers and "reauthenticate every minute" is enabled then CP sends the voucher as username to RADIUS. This causes RADIUS to disconnect the "user/voucher" because of an unknown/wrong "username".
http://redmine.pfsense.org/issues/2155
When stop/start accounting on CP is enabled than the syslog shows many "wrong order" or "Login found bot no logout detected". This seems to not affect the usage of RADIUS but it is not 100% correct.

Dear friends,

I have a stupid question to ask. I've searched on the forum but couldn't find an exact solution to my problem.

I'm modifying the files of FR 2 to make it connect to my mysql server and work flawlessly with my daloradius server. I'm backing up the files I've modified, but the problem is, whenever I reboot the machine, all of the files returns to their original values. So I made a backup of the raddb folder, and whenever I reboot my pfsense, I stop the service, untar the backup I've made, and restart the service.

I want to get rid all of that. Is there any way to make the file changes permanent?

marcelloc

@DestekTeknik:

Edit script that creates config files, it's usually package_name.inc script.

And to keep this file modification on xml backup, use filer package.

Nachtfalke

@DestekTeknik
All files that will be modified by the GUI are in the freeradius.inc:

/usr/local/pkg/freeradius.inc

So the best solution for you would be to modify the freeradius.inc file so that it does what you want.
Then your configuration will survive a reboot :-)

But it will not survive a package reinstallation of freeradius and not a pfsense firmware update.
For this - if I understand marcelloc correctly - you will have a look at the filer package. I didn't ever used the filer package.

After reinstalling freeradius go to the EAP tab and check if the certificates are correct and then click again on "save".
It could also help to change the "cert manager" option on the EAP-tab, click save and then change back and click save again.

New version of freeradius is available:
2.2.0

When looking at the freeradius.org webpage it says:

100% configuration file compatible with 2.1.x. The only fix needed is to disallow "hashsize=0" for rlm_passwd

So this should be no problem for the configuration.

But the makefile seems to have changed - and now different "build options" must be used. Can someone verify this and perhaps make it available for pfsense ?

newbie question. i have reinstalled my pfsense 2.0.1 for 3 times but i don't see the freeradius 2.x as my available package. please advise on how i could have it. thanks for the reply

marcelloc

you have nano or full install????

Nachtfalke

In general freeradius2 package is available for i386/amd64 installations using pfsense version 2.x
Full installation on HDD is supported and it should run on nanobsd installations, too.

Not sure, why it will not be displayed on you installation but you can try this:
1.) login on pfsense
2.) access this URL: http://your_pfsense_IP/pkg_mgr_install.php?id=freeradius2
