MySQL noresetcounter / No reply-name or count attribute?
by Tuc at T-B-O-H.NET 22 May '08

22 May '08

Hi, I've noticed on the default FR 2.0.4 MySQL counter.conf file, for the "sqlcounter noresetcounter" , there isn't a "count-attribute" of "Acct-Session-Time" or a reply-name of something like "Session-Timeout". The dailycounter and monthlycounter both have a reply-name . Is this for a reason, and if so why? I'm just trying to grok why it might not have one compared to the others. Thanks, Tuc

Regards: Sorry my english! I'm using Exec-Program-Wait for session control and printing a "Session-Timeout = 0" parameter, but don' work. In cistron radius, I received logs in radius.log: Tue Sep 4 17:26:57 2007 : Debug: Exec-Program output Session-Timeout:=100 Tue Sep 4 17:26:57 2007 : Debug: Exec-Program-Wait: value-pairs: ,Session-Timeout:=100 But now, I don't received nothing. How I can activate this log in radius.log? _________________________________________________________________ Blog your life in 3D with Windows Live Writer. http://www.windowslive.com/overview.html?ocid=TXT_TAGLM_Wave2_wl_writer_022…

Re: EAP TLS testing using eapol_test
by Naunidh S Chadha 22 May '08

Hi Alan Thanks for the reply. The client certificates are made by using "make client.pem" command. This is the should create the certificates signed by the server certificate of Freeradius. Since the root CA is same for both Freeradius and eapol_test, I am not sure what is going wrong, do you think it could be the eapol config? I will paste it here again. network={ ssid="1x-test" key_mgmt=WPA-EAP eap=TLS identity="user(a)example.com" ca_cert="/usr/local/etc/raddb/certs/ca.pem" (even tried with server.pem as CA) client_cert="/usr/local/etc/raddb/certs/user(a)example.com.pem<http://lists.freeradius.org/mailman/listinfo/freeradius-users> " private_key="/usr/local/etc/raddb/certs/client.key" private_key_passwd="whatever" eapol_flags=3 } Thanks Naunidh On Thu, May 22, 2008 at 10:56 PM, < freeradius-users-request(a)lists.freeradius.org> wrote: > Send Freeradius-Users mailing list submissions to > freeradius-users(a)lists.freeradius.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.freeradius.org/mailman/listinfo/freeradius-users > or, via email, send a message with subject or body 'help' to > freeradius-users-request(a)lists.freeradius.org > > You can reach the person managing the list at > freeradius-users-owner(a)lists.freeradius.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Freeradius-Users digest..." > > > Today's Topics: > > 1.

Thank you Joe for your answer! We all agree that assocation is made before authentication process, in order to RADIUS to be able to do its stuffs. but the fact is that it doesn't work, and i was wondering what would be the result if i set: "Tunnel-Private-Group-ID = 100" (when the SSID were i am connected is assiged to VLAN 200, according to how my device work) . I started to ask silly questions because it's true i don't understand nothing anymore with my config! Basically, i have to use freeradius for authenticate wireless users, all connected on Access points managed by that switch! i learnt freeradius stuffs and with the help of the guys here, i am now able to setup it correctly!!! Access point authentication works well, but end-users authentication doing some EAP fails but stay without no response after the access-challenge!! (saying no correct login/password find, or requiring client certificate, depending if i am doing tls or peap). please note that it deons'nt tell me that my certificates are incorrect, it is the reason why i started to think that the AP's don't relay correctly the EAP negociation! (On XP client client are blocked on "identity validation" then give up the authentication). As i am newbie with 802.1x stuffs, i asked "silly" question to fix out my doubts. it is not easy for me to do it in english! - About the limitations of the device, i posted on d-link support a week ago and i am still waiting for the answer. - about RADIUS assigning SSID... it was a silly question of me and the goal was just to be sure that RADIUS authentication events stay on the same SSID. just for confirmation, and now I KNOW. - the reason of this confusion for me is what the documentation of dws-3024 says on page 205 and 206 as follow (some parts): ############################################################## ############################################################## NOTE: You can configure D-Link Access Points to use 802.1X authentication on the RADIUS server to allow or deny specific users on client stations access to the wireless network. If you enable 802.1X authentication, the client entry on a RADIUS server can support user-based VLANs and subnet assignments for IP tunneling. Table 80 shows the attributes to set for wireless clients within the RADIUS server. Table 80. RADIUS Attributes for Wireless Clients RADIUS Server Description Range Usage Attribute User-Name (1) 1-32 characters Required User-Password (2) 1-128 characters Required Tunnel-Medium-Type (65) 802 Optional ############################################################## The following example shows the entry for a user in the users file. The username is “johndoe,” the password is “test1234.” The user is assigned to VLAN 77. johndoe Auth-Type: = EAP, User-Password == “test1234" Tunnel-Type = 13, Tunnel-Medium-Type = 6, Tunnel-Private-Group-ID = 77 Tunnel-Type and Tunnel-Medium-Type use the same values for all stations. Tunnel-Private- Group-ID is the selected VLAN ID and can be different for each user. NOTE: Do not use the management VLAN ID of the AP for the value of the Tunnel- Private-Group-ID. ############################################################## ############################################################## the documentation also says on page 201: (and i dont understand this step, even using a translator. explanation would be appreciated) ############################################################## NOTE: This appendix does not describe RADIUS configuration for AP network authentication using 802.1X. This feature is separate from a valid AP configuration entry. The edge device that connects to the AP performs the network authentication. The edge device might not be the D-Link Unified Switch. ############################################################## Any people interested in help could just read page 200 - 209 of this documents and give advices. here is the link: ftp://ftp.dlink.fr/DWS/DWS-3024/Manuel/DWS-3000_Series_User_Manual_v2.00.pdf thanks a lot! Joel -------------------------------------------------------------------------------------------------------------------- HI Joel, I think the issue here is that the D-Link AP's you have are rather limited. Radius can not ever assign an SSID because that step occurs before the user authenticated. Wireless starts with an association from the user to the AP's SSID from there the AP decides what needs to happen. Radius can affect VLAN's (generally at least in the Cisco world with 'Tunnel-Private-Group-ID', like you meantioned) but you'll never be able to force a user to switch SSID's because that is client controlled. AP's map VLAN's to SSID's internally some allow n to 1 and 1 to n relationships, others like your d-links only allow a direct mapping. Basically it sounds like you are limited by the constraints of you NAS.

Alan, I possess a device from D-Link (DWS-3024). it is a wireless switch controler, and the documentation says that: - One SSID has to be affect to one VLAN on the profile. - An Access point could be configured with up to 8 ifferent SSIDs and it is possible to affect each SSID on its own network (below is a link which show you the config page) or all SSID on the same network. maybe i didn't read it correctly, so here is the link (see page 89-90 and maybe 91 too.): ftp://ftp.dlink.fr/DWS/DWS-3024/Manuel/DWS-3000_Series_User_Manual_v2.00.pdf i asked you stuffs about SSIDs/VLAN cause all my APs (about 30) will receive the same profile, and the profile will have 3 differents SSIDS with diffrents security access levels and network from the wireless switch. for example, in the same room, associated to the same AP, students and teachers will connect to diffrent SSIDs coming from that same AP, and some will have to athenticate via EAP-PEAP, other will require EAP-TLS. this other short file explain point to point what is my config and waht i am trying to do: ftp://ftp.dlink.fr/DWS/DWS-3024/QIG/QIG_DWS-3024_WPA2.pdf read it and maybe you could understand me. regards Joel MBA OYONE wrote: >> No. VLAN assignment is after SSID association, and after 802.1x >> authentication. > > OK, is it possible to associate in SSID_1 and be assigned to a different > VLAN than the we are associated in ?

Need to understand flow
by Tuc at T-B-O-H.NET 22 May '08

22 May '08

Hi, I'm having to write my own validation and accounting for a device, and I need to understand a little about the flow. Is there a good reference for this? I don't have to support much, basically user/pass authentication, updating accounting, timeout, logoff. I understand that I send it an "Access-Request" packet, and I get back either Access-Accept with potentially some Attributes, or an Access-Reject if it failed. I believe I next need to send an accounting_start packet. Some of the items I'm not sure where they come from (Acct-Session-Id, Acct-Unique-Session-Id) or how they might be generated. During the course of the user being on, I believe you send accounting_updates and at the end send an accounting_stop. One thing I really don't know is where does Max-All-Session come in? In my initial testing, it didn't come back as an attribute. (Maybe incorrectly). Thanks, Tuc

I really need a breakthrough now, I don't think there is anything left that I can do now, may be use some other client or sever for my purpose :) - Naunidh ---------------------------------------------------------------------- Message: 1 Date: Wed, 21 May 2008 20:15:06 +0530 From: "Naunidh S Chadha" <naunidh(a)gmail.com> Subject: EAP TLS testing using eapol_test To: freeradius-users(a)lists.freeradius.org Message-ID: <4b1838520805210745u1a014f31s79bad2914b8602fe(a)mail.gmail.com> Content-Type: text/plain; charset="iso-8859-1" Hi All I am attempting to authenticate an EAP-TLS using eapol_test tool against FreeRADIUS Version 2.0.3. >From last two days I am getting stumped by certificate issues. Currently I have the following error in my Freeradius log that seems to be the problem.

Wed May 21 19:31:19 2008 : Debug: eaptls_process returned 13 >From searching around the net I found that one issue could be that my SSL does not understand that server.pem is a trusted CA. To make that happen I created hashes using the following command, *ln -s client.pem `openssl x509 -hash -noout 5~-in client.pem`.0* for ca.pem/server.pem and client.pem. I then pasted the hashes and .pem files into /usr/share/ssl/certs folder too (out of desperation :) ). After this if I ran the command "openssl verify *.pem" in .../raddb/certs folder, it would return OK for all pem files. IMO this is the best to test that all certificates are in order. I also used the command "openssl verify -CApath . *.pem" (picked it up from Makefile) and it returned OK too. I must add here that my setup is totally as per the docs/config file explanations. The radiusd.conf is configured to use EAP as per the default config, and the certs are made by running the make command in raddb/certs folder. I commented out bootstrap for my exploration. I ran "make client.pem" to create client certificates. The supplicant client uses following configuration file: network={ ssid="1x-test" key_mgmt=WPA-EAP eap=TLS identity="user(a)example.com" ca_cert="/usr/local/etc/raddb/certs/ca.pem" client_cert="/usr/local/etc/raddb/certs/user(a)example.com.pem" private_key="/usr/local/etc/raddb/certs/client.key" private_key_passwd="whatever" eapol_flags=3 } Since the logs are big enough to be a torture for people reading in digest mode, I have put them at http://naunidh.googlepages.com/logs It has output of radiusd -XXX followed by logs of eapol_test tool. My OpenSSL version is 9.7a (supported by Freeradius), My next step would be to upgrade this but it does not look like an OpenSSL issue, Upgrading this would be a pain at the moment as lot of people are dependent on the setup, but this is the only recourse left from my side. Any help would be greatly appreciated. Sorry for the long mail, but I could not shorten it any more without missing something important. Thanks All - Naunidh
