Detailed Logging freeradius Request Packets
by Jean-Francois Mousinho 28 Oct '19

28 Oct '19

Hi, I've tried to find a way of detail logging the packets sent by freeradius to the client in the authentication phase but didn't found a way of doing it. Maybe I've not looked correctly so I'm asking if it's actually possible? I was able to log detailed packets sent by the client (Response packets) but not the ones sent by freeradius to the client (except accounting and proxied ones). Thanks for your time.

Quoting tnt(a)kalik.net: >>>> Is there a way to change the reply from Access-Reject, to Access-Accept? >>>> > > Change freeradius.internal attribute Packet-Type in Post-Auth-Type Reject > section. Changing freeradius.internal Packet-Type from Access-Reject to Access-Accept would affect ALL logins - even logins which *should* be rejected. I'm referring to changing Access-Reject to Access-Accept under certain circumstances only -- not globally for all logins. ...or am I misunderstanding what you're suggesting? Thanks Henry

Freeradius 2 , TTLS/PAP, multiples questions
by Jérôme BERTHIER 19 Jun '12

19 Jun '12

Hi, I'm trying to configure Freeradius 2 to implement EAP/TTLS-PAP authentication method on my Cisco AP1242. It works but I'd like some precisions to get configuration files as small as possible. What is the shortest way to configure it ? authorize { preprocess auth_log suffix eap { ok = return } files ldap pap } authenticate { Auth-Type PAP { pap } Auth-Type LDAP { ldap } eap } Are the lines correct ? Moreover, I've got trouble to implement few functions. First, what's the right way to implement check for Simultaneous-Use ? For cisco nas type, Freeradius seems to use snmp check but where should I configure SNMP read community in order to make it possible ? Then, during EAP process, is it possible to check if inner identity equal outer identity and if not to reject request ? Finally, I've got problem with NetworkManager under Fedora 9 (not tested on other distribution). If Session resumption / fast reauthentication cache is not enabled, clients can't reassociate and ask for session resumption again. Is there a workaround ?

test suite simulating NAS for development?
by Mark McWiggins 14 Feb '12

14 Feb '12

Hi All, We're developing an application to capture log data from Radius, but we don't have a NAS to test with to generate the logs. Is there some test suite available to do this? Thanks much; if none is available we will probably develop one and I think our management will consent to share it. -- Mark McWiggins Client Integration Engineer mark.mcwiggins(a)messagesystems.com 443-656-3311 ext 344

Daily accounting
by David Roze 02 Dec '11

02 Dec '11

Hi everyone, I have seen a lot of people who are trying to get traffic accounting collected at regular intervals to generate graphs and view per day/month etc... I have made a few modifications in order to achieve this. You can see it at http://www.netexpertise.eu/en/FreeRadius/DailyAcct.html It works on Mysql setup but can be adapted to any db. I'd be grateful to get some feedback on this. A lot of ISPs are running into this problem. Hope this helps Regards, David

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?
