Freeradius and WiMAX Access Point
by Ming-Ching Tiew 22 May '09

22 May '09

I shall not name the vendor name here. I just got some info from the vendor that the WiMAX Access Point does not do 'interim accounting', 'acctupdate' and so on. Only thing possible right now is authenticate and start/stop accounting. That being the case, I wonder how one implement stuff like fair-use policy on a WiMAX user ? If the radius server does not get interim accounting, the way the users is going to "cheat" is just to power off the device at the end of his usage !!! Am I missing something here ? The way I see it is that if one have to implement a more intelligent authentication and accounting, for WiMAX, one has to put a box, either as a bridge or as a router in front of the APs, where all the data path goes through the box. And that box will create session information and accounting on behalf of the APs. If one has to introduce this box, using Linux solutions, what would be the right way to do this, so that the traffic accounting can be done on each APs ? ( iptables or Coova chilli comes to my mind ). How does the commercial solutions work ? Anyone care to share his knowledge on this ? Once again thanks for reading and best regards. Ming-Ching

That's actually wrong. It was true a while ago, but it's not true in 2.1.6. However... defining two proxy listeners won't do what he wants in 2.1.6. I've committed a patch to git head. See http://git.freeradius.org/pre/ for a snapshot of 2.1.7-pre that includes the fixes. See raddb/proxy.conf, and look for "src_ipaddr".

FreeRadius+wimax asn gw
by Denis K 22 May '09

22 May '09

Dear All, I'm trying to configure radius as a AAA server for WiMAX ASN GW. I've generated certs and have added them to a ASN. Auth is work ok. I've got access-accept, but after this I need to discribe a service for wimax user, parametrs such as QoS, Servic flow, static ip etc. Where should I add them? How to create a service? Is where any documentation aboute it? thanks in advance -- View this message in context: http://www.nabble.com/FreeRadius%2Bwimax-asn-gw-tp23666799p23666799.html Sent from the FreeRadius - User mailing list archive at Nabble.com.

I am pretty new to this too but I think you have to send back some reply attributes which the ASN gateway can understand and can enforce it. As to what attributes the ASN gateway can understand, I suppose this is vendor specific. --- On Fri, 5/22/09, Denis K <denis(a)tojikiston.com> wrote: > From: Denis K <denis(a)tojikiston.com> > Subject: FreeRadius+wimax asn gw > To: freeradius-users(a)lists.freeradius.org > Date: Friday, May 22, 2009, 8:53 AM > > Dear All, > > I'm trying to configure radius as a AAA server for WiMAX > ASN GW. > I've generated certs and have added them to a ASN.

How to: freeRADIUS with PostgreSQL Backend!
by Just E. Mail 22 May '09

22 May '09

I have setup a working freeRADIUS server & now want to add PostgreSQL as backend for storage of data. I have read the freeRADIUS documentation and researched the internet on this subject. What I am looking for is any kind of Step-by-Step document detailing sequential steps needed to setup a PostgreSQL back end for freeRADIUS. Has someone written such a document? Is there such a writeup available?

May I ask if I am using sql to store the client list in the sql table 'nas', is there a way for me to ask freeradius to refresh the list ? Or is it that I must kill and restart freeradius ? Regards.

usr-hiper and freeradius 2.1.5 accounting problem
by haries fajar nugroho 22 May '09

22 May '09

Hi All, I wanna migrate my radius server from icradius to freeradius 2.1.5. i have two ras modem for my nas (patton and usr-hiper). When I do some migration simulation, client that connect from patton goes normally (authentication,accounting,authorization). But when they use usr-hiper (system version :V5.1.6/Non-Encr), the client could connect to the network but the accounting goes wrong. In my freeradius debugging mode, the error message was : rad_recv: Accounting-Request packet from host x.x.x.x (* encrypted ip) port 1646, id=63, length=405 Received Accounting-Request packet from x.x.x.x (* encrypted ip) with invalid signature! (Shared secret is incorrect.) Dropping packet without response. Going to the next request Waking up in 0.9 seconds. The usr-hiper accounting settings : HiPer>> sh accounting RADIUS ACCOUNTING SETTINGS The Primary Server Status is: ENABLED Primary Server is: x.x.x.x(* encrypted ip) Primary First Backup Server is: 0.0.0.0 Primary Second Backup Server is: 0.0.0.0 Primary Destination Port is: 1648 Primary First Backup Destination Port: 1646 Primary Second Backup Destination Port: 1646 Primary Preference: 1 Primary First Backup Preference: 2 Primary Second Backup Preference: 3 Max Primary Retransmissions: 0 The Secondary Server Status is: ENABLED Secondary Server is: 0.0.0.0 Secondary First Backup Server is: 0.0.0.0 Secondary Second Backup Server is: 0.0.0.0 Secondary Destination Port is: 1646 Secondary First Backup Destination Port: 1646 Secondary Second Backup Destination Port: 1646 Secondary Preference : 1 Secondary First Backup Preference: 2 Secondary Second Backup Preference: 3 What I have tried to solve it : 1. I've tried to make multi port for accounting packet (1646 & 1648), because i thought that the error message refer to wrong accounting port. But the accounting still wrong. 2. I've tried to use default freeradius secret at the freeradius side with testing123 without changing the secret at the ras modem. But still failed. Do you have another solution ? Thanks before :)

accounting with 802.1X: some clients trigger multiple starts at a time
by Sam Hooker 22 May '09

22 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi folks, We're running SQL accounting for the FR servers authenticating our 802.1X users, now. I'm seeing some annoying duplicate entries, and am wondering if anyone else has had this experience: mysql> SELECT acctsessionid, username, nasipaddress, acctstarttime, callingstationid FROM radacct WHERE acctstoptime IS NULL ORDER BY acctstarttime; +-----------------------------------+------------+-----------------+---------------------+------------------+ | acctsessionid | username | nasipaddress | acctstarttime | callingstationid | +-----------------------------------+------------+-----------------+---------------------+------------------+ ... | 4a15bfef/00:23:12:07:e9:c4/74507 | [redacted] | 10.246.207.234 | 2009-05-21 16:56:15 | 192.168.2.17 | | 4a15bfef/00:23:12:07:e9:c4/74505 | [redacted] | 10.246.207.234 | 2009-05-21 16:56:15 | w.x.38.213 | | 4a15bfef/00:23:12:07:e9:c4/74514 | [redacted] | 10.246.207.234 | 2009-05-21 16:56:15 | 10.250.61.133 | | 4a15bfef/00:23:12:07:e9:c4/74516 | [redacted] | 10.246.207.234 | 2009-05-21 16:56:15 | 192.168.1.25 | | 4a15bfef/00:23:12:07:e9:c4/74513 | [redacted] | 10.246.207.234 | 2009-05-21 16:56:15 | w.x.38.213 | ... I would think this to be pretty normal-looking, except: 1) in this particular group, all the usernames and MAC components of the acctsessionid are the same (i.e., this is one node causing multiple accounting starts to be sent); and 2) our 802.1X wireless clients would not have IP addresses in RFC1918 space. Ever. Most of the time, a group like this will include an address in our real wireless address range (that's what I've replaced with "w.x.38.213"), but sometimes not. If the callingstationid weren't different for each entry, I'd think "retries" or "EAP-FAST". (I think I see EAP-FAST activity going on elsewhere; or, at least, that's what I assume it is.) As far as I can tell, this occurs pretty infrequently, given the number of users we have, but it does occur consistently for a given set of users in a given day, which makes me think it's something about their location on the network. Reducing all the accounting detail to a spreadsheet, I see that this is a flurry of start and stop messages (and one Interim-Update!), and will comb through that closely tomorrow morning. Seems odd, though, that there would be a stop logged to the detail, but not to SQL, in this case. I have little- to no visibility into the networking configuration (our systems and network groups bristle at each other; a situation I'm trying to remedy), but I do know this: One department is located across the street from our main campus. It connects to the Internet by way of a commodity ISP. It is, however, close enough to pick up one of our APs, and the enterprising IT guy for that department has set up a Windows box as a wireless client, and bridged that into their LAN for access to institutional resources. (He has been duly chastised for this.) In at least that case, I've seen their LAN IPs (in a reasonably-unusual RFC1918 subnet) as the callingstationid. (Oddly, though, this is sometimes the LAN IP of their print server, or default gateway -- some artifact of bridging?) This makes me think that there are more clients out there that can see more than one subnet at a time, and just report in with whatever IP they feel like. I suppose my real question is this: Is there anything I can do, from the FR server end, to winnow out one reliable accounting entry per event? Sure, I can make my reports (like 'radwho') filter WHERE callingstationid LIKE 'w.x.%', but that runs the risk of missing entries where the group fails to include one of our "legit" addresses. Alternatively, has anyone else faced this and addressed it on the client side? ("Tell the rogue departments to comply with your network policies," is a valid answer and, frankly, my favorite.) As ever, pointers to pre-existing threads answering this are welcome; I couldn't come up with the right combination of search terms to find them myself...

freeRADIUS - New Install testing!
by Just E. Mail 21 May '09

21 May '09

Installed freeradius-2.2.1 (RPM). Installation & configuration went well. RADIUS starts with no problem. "radiusd -XC" output shows no errors. Now I want to do some preliminary testing. In the older versions, I used to run the command: radtest <User> <P/W> localhost <Port> <Secret-Key> and see the output to verify that RADIUS server was up and running. After I did the above install, "radtest" command is not included. How does one test a new freeRADIUS installation? Is "radtest" replaced by another command? Is there any GUI testing tool for RADIUS?
