Hello, Please I 'd to know how to use an ldap as a database of freeradius. I use freeradius-server-2.1.3. Is it possible to use more than one nas in clients.conf ? If yes how to do it? How to configure EAP-TLS ? Thank you for your help. Rato

How to configure proxy server to send a copy of acct to remote/home server
by Difan Zhao 27 Oct '11

27 Oct '11

Dear experts, I configured my Freeradius2.1.7 server to be a proxy server which will forward the PEAP authentication packages to a remote server. The authentication part works great. I configured my switch to send accounting information to the proxy server. The proxy server is using MySQL to store the acct info. This part works fine too. However I'm requested to also send a copy of the acct info to the remote server... I'm still checking my switch (Cisco) and see if it can send two copies of acct info to two different servers at the same time. However, is it possible to make FreeRadius to automatically forward a copy to the remote server?? Thanks! Difan Zhao, M.Eng Network Engineer Guest-Tek Interactive Entertainment Inc.

Freeradius capable of url-redirect
by Nathan McDavit-Van Fleet 15 Aug '11

15 Aug '11

Cisco has a feature to redirect users to a splash page after 802.1x/WPA2-personal authentication. We are interested in this feature so we can notify users of our EAP-TTLS service that we are migrating to PEAP-MSCHAPv2. I have included the url for the configuration description (of Cisco ACS). But essentially there is a av-pair and url-redirect attribute which need to be configured on Cisco ACS (and some other wireless configs) in order to enable that option. I am not talking about a captive portal. We want to display a info page for the users of a specific protocol. The document below describes that it happens after authentication and network access. http://www.cisco.com/en/US/products/ps6366/products_configuration_example091 86a0080956185.shtml Is this handled somehow is Freeradius?

rlm_sql: "NUMERIC VALUE OUT OF RANGE" error

Freeradius 2.1.0. I have a NAS which sends a NAS-Port-Id attribute in the range 2147483648..2164260863. PostgreSQL doesn't like the query Freeradius performs.

If this is not supported by the accounting, is there a way to get it from the authentication section? Would also like to say that I know this is more related to the PAM module and I assume this makes this mail a bit out of context in this mail group, but any help would be most appreciated.

pam_auth_radius
by Marc Phillips 16 May '11

16 May '11

Not sure if this is the appropriate forum for this, but I'll type it anyway. I have a need to add centralized auth and accounting to unix boxes (specifically a linux based "appliance." It's not really an actual appliance, just a standard linux box that a vendor provides). For my normal unix* boxes I have an identity management system. For appliances and network devices I use Radius, mostly. For this new appliance, I'd like to use Radius, but I don't want to manage users or what groups they belong to on the device itself. I'd like to have the users auth against Radius and then apply a group based on an attribute recieved. I've done a little looking and I see no group support for pam_auth_radius. One thought I had was to add some sort of auto provision function to the pam module to add the user and associate that user with a group via the supplied attribute from radius, then remove the user on logout. Any thoughts on this? Is there some other method that would be more appropriate? I have use for this for other psuedo-appliances. I've tried using LDAP for those, but the chatter with vendor supplied ldap modules was unmanagable. R. Marc

EAP-TTLS & Kerberos
by Thorsten Fischer 20 Apr '11

20 Apr '11

All, I have a number of NASs - wireless APs running hostapd. I am setting up a freeradius 2.1.10 server to control the authentication of username(a)net.example.com to the wireless network; the decision is to be made by a Kerberos server. The setup is not working as intended, which I think stems either from my misunderstanding of the protocols involved or of how to set up freeradius correctly. Or both. Later, all authentication requests of username(a)example.com (without the net.) are to be forwarded to another Radius server. There will likely be more services integrated in the same vein later, so I would like to branch out into separate virtual servers based on realm. My understanding is that the communication between a user(a)net.example.com and freeradius needs to involve EAP-TTLS, because of the cleartext password which is required to be passed on to kerberos. The required keytab is set up and configured correctly. modules/krb5 is set up accordingly. bootstrap in raddb/certs has been run to create self-signed certs. I have an entry in the users file: DEFAULT Realm == "net.example.com", Auth-Type = Kerberos The realm is set up like this: realm net.example.com { virtual_server = net.example.com } And the virtual server as well as the inner-tunnel have Auth-Type Kerberos { krb5 } in their authenticate section, right after Auth-Type PAP. Key changes in eap.conf: eap { default_eap_type = ttls ttls { default_eap_type = md5 copy_request_to_tunnel = yes use_tunneled_reply = yes } } Local tests succeed as follows: $ radtest -t pap thorsten(a)net.example.com pwd 127.0.0.1 0 testing123 $ radtest -t eap-md5 thorsten(a)net.example.com pwd 127.0.0.1 0 testing123 $ radtest -t pap thorsten(a)net.example.com pwd 127.0.0.1:18120 0 testing123 In each of these cases, the reason for success is successful communication with Kerberos, as exemplified by the following lines (and wrong kerberos passwords let authentication fail): Wed Feb 2 15:59:06 2011 : Info: Found Auth-Type = Kerberos Wed Feb 2 15:59:06 2011 : Info: # Executing group from file /etc/freeradius/sites-enabled/net.example.com Wed Feb 2 15:59:06 2011 : Info: +- entering group Kerberos {...} Wed Feb 2 15:59:06 2011 : Info: ++[krb5] returns ok Wed Feb 2 15:59:06 2011 : Auth: Login OK: [thorsten] (from client localhost port 0 via TLS tunnel) However, tests with eapol_test locally as well as with the actual access points fail: $ cat eap-ttls.conf network={ ssid="myssid" key_mgmt=WPA-EAP eap=TTLS identity="thorsten(a)net.example.com" password="pwd" phase2="auth=PAP" } $ eapol_test -c eap-ttls.conf -s testing123 produces: rad_recv: Access-Request packet from host 127.0.0.1 port 60596, id=0, length=172 User-Name = "thorsten(a)net.example.com" NAS-IP-Address = 127.0.0.1 Calling-Station-Id = "02-00-00-00-00-01" Framed-MTU = 1400 Calling-Station-Id ="02-00-00-00-00-01" Framed-MTU = 1400 NAS-Port-Type = Wireless-802.11 Connect-Info = "CONNECT 11Mbps 802.11b" EAP-Message = 0x020000250174686f727374656e406e65742e742d6c6162732e74752d6265726c696e2e6465 Message-Authenticator = 0x3f0be4354cfc77a6285a0ad074341101 Wed Feb 2 15:33:32 2011 : Info: # Executing section authorize from file /etc/freeradius/sites-enabled/default Wed Feb 2 15:33:32 2011 : Info: +- entering group authorize {...} Wed Feb 2 15:33:32 2011 : Info: ++[preprocess] returns ok Wed Feb 2 15:33:32 2011 : Info: ++[chap] returns noop Wed Feb 2 15:33:32 2011 : Info: ++[mschap] returns noop Wed Feb 2 15:33:32 2011 : Info: ++[digest] returns noop Wed Feb 2 15:33:32 2011 : Info: [suffix] Looking up realm "net.example.com" for User-Name = "thorsten(a)net.example.com" Wed Feb 2 15:33:32 2011 : Info: [suffix] Found realm "net.example.com" Wed Feb 2 15:33:32 2011 : Info: [suffix] Adding Stripped-User-Name = "thorsten" Wed Feb 2 15:33:32 2011 : Info: [suffix] Adding Realm = "net.example.com" Wed Feb 2 15:33:32 2011 : Info: [suffix] Proxying request from user thorsten to realm net.example.com Wed Feb 2 15:33:32 2011 : Info: [suffix] Preparing to proxy authentication request to realm "net.example.com" Wed Feb 2 15:33:32 2011 : Info: ++[suffix] returns updated Wed Feb 2 15:33:32 2011 : Info: [eap] Request is supposed to be proxied to Realm net.example.com.

Freeradiusd 2.1.8
by Brian Carpio 21 Mar '11

21 Mar '11

I have a production environment which is running freeradiusd 2.1.8 and last night in the logs I see the following message Sat Jan 1 20:11:24 2011 : Error: Mon Jan 10 17:04:58 2011 : Info: Exiting normally. No one was on the box doing anything... I was looking into this issue with google and came across a thread back in Nov 2009 about an issue a user was experiencing with radiusd 2.1.8, and this user send some gdb dumps to the development team... I can't seem to recreate the issue as quickly as he does (plus my server is in production) but I didn't see any follow up if this is a known bug? Is this fixed in 2.1.10? Thanks, Brian
