Hi all, I am a complete newbie with radius. I have try to configure freeradius on fedora core 3 to authenticates against unix password /etc/passwd, /etc/shadow, but seem to be fail until now.. can any want pls guide me though this.. Besides, pls advice me if i doing anything wrong. My installation step:- 1) install freeradius using apt-get command:- ===================================================================== [root@cerebro ~]# apt-get install freeradius ===================================================================== 2) As i go though the doc, the default seem to be ok.., so i just start the services:- ===================================================================== [root@cerebro ~]# /etc/init.d/radiusd start Starting RADIUS server: [ OK ] [root@cerebro ~]# ===================================================================== 3) add a dummy user and assigh a password to user dummy:- ===================================================================== [root@cerebro ~]# adduser dummy [root@cerebro ~]# passwd dummy Changing password for user dummy. New UNIX password: testing BAD PASSWORD: it is based on a dictionary word Retype new UNIX password: testing passwd: all authentication tokens updated successfully. [root@cerebro ~]# ===================================================================== 4) testing to autheticate the user dummy:- ===================================================================== [root@cerebro ~]# radtest dummy testing localhost:1812 1 testing123 Sending Access-Request of id 251 to 127.0.0.1:1812 User-Name = "dummy" User-Password = "testing" NAS-IP-Address = cerebro.osedge.com NAS-Port = 1 Re-sending Access-Request of id 251 to 127.0.0.1:1812 User-Name = "dummy" User-Password = "\271g\343\034{~\235\364M\344ID%\345\021j" NAS-IP-Address = cerebro.osedge.com NAS-Port = 1 rad_recv: Access-Reject packet from host 127.0.0.1:1812, id=251, length=20 [root@cerebro ~]# ===================================================================== The output of /var/log/radius/radius.log ===================================================================== [root@cerebro radius]# tail -f /var/log/radius/radius.log Thu Jul 28 03:54:16 2005 : Info: rlm_exec: Wait=yes but no output defined.

Colubris-AVPairs
by Andrey 27 Jul '05

27 Jul '05

Hi, I have a problem with Freeradius returning Colubris-AVPairs. I have a CN3300 (Colubris AP) set up to authenticate from my radius server (FR), which in turn passes it information such as login pages, access lists, etc. All these attributes are defined in my "radgroupreply" table (3 in all), which look something as follows: 151 colubris_group Colubris-AVPair := access-list=loginserver, ACCEPT, tcp, x.x.x.138, ALL 152 colubris_group Colubris-AVPair := use-access-list=loginserver 153 colubris_group Colubris-AVPair := login-url=http://x.x.x.138/colubris/login.html When I attempt to authenticate the AP, the Access-Accept response has only the first Colubris-AVPair, whichever it might be (i've tried different orders). Is there any reason for this kind of behaviour? Do attributes have to have unique names? (since all three are called Colubris-AVPair). Thanks for any help. -Andrey

questions about a custom freeradius configuration
by Jeff Smith 27 Jul '05

27 Jul '05

Hi, Our wireless network currently authenticates and authorizes users via freeradius 0.8.1 with a custom module that talks to custom authentication and authorization servers. I'm upgrading the server side to freeradius 1.0.4. At the same time, the people who run the wireless network are switching to using EAP-PEAP with MS-CHAP v2. I'm fairly new to freeradius, but I have been spending a lot of time reading this list, the documents, the O'Reilly book, and experimenting with the server. So far I've been able to do PEAP authentications to the server via the users file. The custom authentication module I referred to in the first paragraph basically re-implemented MS-CHAP v2 and talked to the custom servers on the back end. It would not be easy to wedge into the rlm_eap code. Instead, I'd like to find a solution that makes the fewest possible (if any) modifications to stock freeradius, so we can track releases more closely. I would like to continue using the custom authentication and authorization servers. My thinking on this so far is that I might be able to use the Exec-Program-Wait atribute and/or the rlm_perl modules to call out to the custom servers, which have command-line interfaces. Ideally, I'd be able to do something like this: 1) In the authorization phase, call out to the custom authorization server and ask a question like "Is this user who claims to be ``joe'' authorized to use the wireless service?" I can get back a yes/no answer and send an Access-Reject with an explanation, or continue on if they are authorized. (I don't think Exec-Program-Wait can help here since I understand it only gets called after the user is authenticated. I could make this check after and only if mschap returns success, though.) 2) In the authorization phase, also call out to the custom authentication server to get pack the NT-Password and add that to the value pairs in the check list in the request packet, so that when EAP-PEAP finally gets down to the MS-CHAP v2 part, the NT-password is available. I have been having a hard time getting my mind around the complexity of RADIUS and freeradius. It may be that I'm taking a completely wrong-headed approach here. If anyone on this list has any thoughts on how this could be done best, I'd appreciate hearing your ideas. Thanks in advance!

Can Calling-Station-Id be proxied
by shane 27 Jul '05

27 Jul '05

Hi, Does freeradius proxy the Calling-Station-Id ? I am sending a realm to another radius server that will record the mac address of the users computer. Effectivly locking the user login to the mac address. It seems the "Calling-Station-Id" is not proxied to the main server. *************************************** Sending Access-Request of id 4 to 127.0.0.1:1820 User-Name = "test" User-Password = "test" NAS-IP-Address = 10.0.0.100 Proxy-State = 0x33 *************************************** Is ther a way to send additional details with the proxy request? Thanks

mod_radius, apache2 and the auth cookie.
by Palmer J.D.F. 27 Jul '05

27 Jul '05

Hi, Is it possible to set the timeout for the auth cookie used by the mod_radius authentication module to 0; by Zero I mean no time, not infinite time? Or, is there a way that I can clear the cookie on a failed login? At present, if a user login fails the user has to close the browser and open another in order to be able to re-enter their credentials, I want to try to get round this if possible. It doesn't matter that the login will timeout immediately. Many thanks, Jezz Palmer. **************************************** Jezz Palmer. Internet Systems Officer.

Re: rlm_ldap: Attribute "User-Password" isrequired forauthentication
by Stefan.Neis＠t-online.de 27 Jul '05

27 Jul '05

Hi, (snipp) > modcall[authorize]: module "files" returns ok for request 0 > modcall: group authorize returns updated for request 0 > rad_check_password: Found Auth-Type LDAP > auth: type "LDAP" > Processing the authenticate section of radiusd.conf > modcall: entering group Auth-Type for request 0 > rlm_ldap: - authenticate > rlm_ldap: Attribute "User-Password" is required for authentication. (snipp) > Any ideas where I might go wrong? I guess you're telling the RADIUS server to _always_ do LDAP, even if it's the "outer" protocol where "EAP-TTLS" is needed, not only for the "inner" protocol which is using PAP. Look into the mailing list archives for "FreeRadius-Proxied-To" (or something similar) on how to tell apart packets of "outer" and "inner" protocol and set the Auth-Type only for the "inner" one. Hope this isn't to cryptic and does help, Stefan
