Correct RegEX format for virtual server in proxy.conf
by Sallee, Stephen (Jake) 17 May '11

17 May '11

I am trying to follow the excellent instructions in the proxy.conf file for setting up a virtual server using realms, however I keep getting an error when I try to start radisud -X telling me that the regex is invalid... here is my realm decleration, what am I doing wrong? realm "~*\\.cru$" { } realm "~*\\.cru\\.umhb\\.edu$" { } realm "~*\\.umhb$" { } realm "~*\\.umhb\\.edu$" { } I know the realms are blank at this time so they do effectively nothing, but one step at a time : ) And here is the error from startup: realm LOCAL { } realm ~*\.cru$ { /etc/raddb/proxy.conf[676]: Invalid regex in realm "~*\.cru$" } # realm ~*\.cru$ Jake Sallee Godfather of Bandwidth Network Engineer University of Mary Hardin-Baylor 900 College St. Belton, Texas 76513 Fone: 254-295-4658 Phax: 254-295-4221

ok, I just wanted to get your suggestions if there is any (It seems there is no) and start to implement it. Thanks for your attention. I'll soon ask my specific questions here.

using freeRadius to authentic a user to access different sources with different configuration
by Abbas Yazdanpanah 17 May '11

17 May '11

Dear all, There is a NAS and I want to authenticate users. I have two resources, the first one the is Internet and the second is an intranet. I've two access policies regarding to each source. for example a policy is "users have different bandwidth for accessing each source". I've a proprietary radius server and have used its scripting abilities to set the second resource policy. It must be said that the second resource policy is identical for all users. It has been decided to migrate our system to freeRadius (due to the expenses) and also there is a change in policies so the second resource policy is not identical for all users any more. Due to my lack deep experience in freeRadius, I was wondering if there is any suggestion that would help me about this scenario. Regards, Abbas.

attrs.pre-proxy in V2
by Steve Brown 17 May '11

17 May '11

Hi chaps, I'm slightly confused with the different V2 semantics. I'm trying to truncate the Framed-IP-Address to the first three quads for a particular realm (somerealm below) when a particular attribute contains particular text: In pre V2, something like this would do the trick: somerealm Some-Attribute == "Some,text" Framed-IP-Address =~ "^([0-9]+\.[0-9]+\.[0-9]+)\.[0-9]+", Framed-IP-Address := `%{1}`, Fall-Through = Yes What would the equivalent rule for V2 be? The above doesn't appear to do what I want. Steve

Using LDAP with EAP-TLS
by Alexandros Gougousoudis 17 May '11

17 May '11

Hi, I'am trying to make FR 2.1.10 on Squeeze work with my LDAP installation. What I want to do is: A host-based authentification for my workstations. All the names of the workstations are in LDAP, the authentification itself should be done with EAP-TLS. I would like to have a hint, how to start EAP when the LDAP-Query was successfull. The LDAP-Query works I think, FR says: [ldap] user scit-beerchen authorized to use remote access, but then it tries to make some kind of password authentification (I have no password for workstations in LDAP), and is not starting EAP-TLS. The asking host "scit-beerchen" is in the WLAN-User Group. What could I do? Please have a look on my Debug-Output: rad_recv: Access-Request packet from host 10.48.244.28 port 3079, id=0, length=139 User-Name = "scit-beerchen" NAS-IP-Address = 10.48.244.28 Called-Station-Id = "0016b64f44cc" Calling-Station-Id = "002268c63ff2" NAS-Identifier = "0016b64f44cc" NAS-Port = 11 Framed-MTU = 1400 NAS-Port-Type = Wireless-802.11 EAP-Message = 0x0200001201736369742d626565726368656e Message-Authenticator = 0x12969f7ffa42f57be53a54474c1274be # Executing section authorize from file /etc/freeradius/sites-enabled/default +- entering group authorize {...} ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop ++[digest] returns noop [suffix] No '@' in User-Name = "scit-beerchen", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] returns noop [ntdomain] No '\' in User-Name = "scit-beerchen", looking up realm NULL [ntdomain] No such realm "NULL" ++[ntdomain] returns noop [eap] EAP packet type response id 0 length 18 [eap] No EAP Start, assuming it's an on-going EAP conversation ++[eap] returns updated ++[files] returns noop [ldap] performing user authorization for scit-beerchen [ldap] expand: %{Stripped-User-Name} -> [ldap] ... expanding second conditional [ldap] expand: %{User-Name} -> scit-beerchen [ldap] expand: (uid=%{%{Stripped-User-Name}:-%{User-Name}}) -> (uid=scit-beerchen) [ldap] expand: dc=verwaltung,dc=kh-berlin,dc=de -> dc=verwaltung,dc=kh-berlin,dc=de [ldap] ldap_get_conn: Checking Id: 0 [ldap] ldap_get_conn: Got Id: 0 [ldap] attempting LDAP reconnection [ldap] (re)connect to physalis:389, authentication 0 [ldap] bind as / to physalis:389 [ldap] waiting for bind result ...

It sets the hole Expression to FALSE. I think that's fixed in the v2.1.x branch in git. The fix will be in 2.1.11. Alan DeKok.

HUAWEI MA5200G and Vendor Specific Attributes
by Ali Majdzadeh 17 May '11

17 May '11

Hello All I’m using freeradius 1.1.8 with a C external program for auth/acct. I’m sending attributes to RAS by printf . RAS type is HUAWEI MA5200G And I send attributes as follows: printf("Session-Timeout=%d",session_time); printf(",\nInput-Peak-Rate=%d",(int)rx_burst); printf (",\nInput-Average-Rate=%d",(int)rx_rate); printf(",\nOutput-Peak-Rate=%d",(int)tx_burst); printf(",\nOutput-Average-Rate=%d",(int)tx_burst); the last 4 lines are HUAWEI vendor specific attributes. MA5200G RAS Debug does not show any attributes inside of auth request. I remove the HUAWEI vendor specific attributes (the last 4 lines), RAS shows the standard attributes correctly. What is the problem? HUAWEI says it support only radius 1.1, So does freeradius support 1.1 when sending attributes by printf via external program or not?

variable string replace (i presume using UNLANG?)
by Steve Staples 16 May '11

16 May '11

Hi all, I am looking to replace a string, before sending the query off to sql... right now, it is %{SQL-User-Name} (sql_user_name = "%{User-Name}" ), but the value is going to be like: mppp%sstaples(a)domain.com and i want to remove the mppp% (which will always be prefixed, or not exist) so that the variable only is sstaples(a)domain.com Is that easy to do? I have searched the docs, but came up empty (sorry if it has been discussed already... just didnt find it) I could always write it in the query to replace the string: SELECT REPLACE('mppps%sstaples(a)domain.com', 'mppp%', ''); but not sure if that is the most efficient way to do it? Thanks in advance. Steve.
