Proxying PEAP/MSCHAPv2 to NPS errors
by Seth Lampman 20 Nov '12

20 Nov '12

Freeradius 2.2.0 I am trying to take an PEAP/MSCHAPv2 tunnel terminate it at 172.16.0.9 and then proxy it as MSCHAPv2 to an NPS server at 172.16.0.15. This is for a token server that does not allow PEAP. Everything works (I get an ACCEPT from 172.16.0.15) but then freeradius crashes. I have searched the forumns and it looks like others have had this issue but I can seem to find a resolution. Sometimes I get the mutex lock and sometimes I get a segmentation fault. Any help would be greatly appreciated. ----SNIP OF ERROR FROM DEBUG---- rad_recv: Access-Accept packet from host 172.16.0.15 port 1812, id=24, length=230 Proxy-State = 0x313137 Framed-Protocol = PPP Service-Type = Framed-User Class = 0xce4e0b840000013700010200ac10000f00000000c1f0b6db791d9ba301cdc5f9ffdd9c5000 00000000000013 MS-MPPE-Recv-Key = 0x23f719b0d45157837af9e2d7fbdba7dd MS-MPPE-Send-Key = 0x13a8461f37b23d89591fdb2a2f02f1ce MS-CHAP2-Success = 0x06533d45413643313739303838373942324634394134304233443137353646454131324346 373637443143 MS-CHAP-Domain = "\006SKL" # Executing section post-proxy from file /etc/freeradius/sites-enabled/default +- entering group post-proxy {...} [eap] Doing post-proxy callback [eap] Passing reply from proxy back into the tunnel. server inner-tunnel { [eap] Passing reply back for EAP-MS-CHAP-V2 # Executing section post-proxy from file /etc/freeradius/sites-enabled/inner-tunnel +- entering group post-proxy {...} ++[eap] returns noop WARNING: Empty post-auth section.

FreeRadius Novice problems
by Tzvika Gelber 19 Nov '12

19 Nov '12

Hello, I'm seeking help as I'm very new to FreeRadius and I'm trying to do a lot of things that I know FreeRadius can do but I don't know how to do it. I'm hoping someone can point me in the right direction. I'm a novice when it comes to FreeRadius and not that big of an expert in Linux. I have FreeRadius installed and I added the user I wanted and I can authenticate with EAP with my WiFi clients. Server info: Core I3 with 2Gb ram running Ubuntu 12.04 Installed: FreeRadius 2.1.10 L.A.M.P server (full) My questions: 1. How do I create users that have a specific vlan attached to them (say user2 will always associate Vlan2 when connected), user1 is untagged so it's vlan1, user2 is attached to vlan2 and so on and so on. a. As I explained I have one user (untagged) running and working, but I would like to prevent the locking of this user so a lot of connections will be allowed to use the same Username (this is a lab environment not production) 2. Accounting: how do I enable accounting? a. How do I view the accounting file for each connected user? i. And since I have MySQL installed is there a way to view this on a GUI? b. Can I have accounting for none authenticated users (since this is a Wifi testing lab we need the user to be in "open" mode and Also enable accounting) – how? 3. GUI: is there a management GUI for FreeRadius and if so how do I install it? Thank you very much. -- ____ Sometimes you just glow in the dark...

Personalizing ldap filters from users file
by Angel L. Mateo 19 Nov '12

19 Nov '12

Hello, I have freeradius (2.2.0) using ldap as backend for user information. This radius server is used by different applications to authenticate and authorize users. I want now to use different ldap filters for different applications. In LDAP I'm using SCHAC schema and schacUserStatus is a multivalue attribute (in URN format) indicating services that the user has enabled or disabled in the way: dn: uid=user,<basedn> uid: user schacUserStatus: <urn prefix>:dovecot:enabled schacUserStatus: <urn prefix>:eduroam:enabled schacUserStatus: <urn prefix>:vpn:disabled ... What I want is to define ldap filter as: ldap { ... filter = "(&(mail=%{User-Name})(schacUserStatus=<urn prefix>: %{X-Atica-Service}:enabled))" ... } where "X-Atica-Service" is a private attribute (of type string) I have defined in dictionary, and this attribute is defined in users file for the each with something like: DEFAULT X-Actica-Service = 'vpn', Auth-Type = LDAP, Realm == um.es User-Name := `%{User-Name}`, Fall-Through = No But this does not work. As I have a virtual server for each service radius is authenticating I don't mind defining this attribute in virtual server configuration. What I want to avoid is to define different ldap modules differing just the filter. Any idea? -- Angel L.

radwho: No configuration information in radutmp section of radiusd.conf
by Angel L. Mateo 19 Nov '12

19 Nov '12

Hello, I have a problem with radwho since I upgraded from 2.1.10 to 2.2.0. The same configuration (I'm trying now the default configuration installed from ubuntu packages) works with version 2.1.10 and not with 2.2.0. The error I get is; radwho: No configuration information in radutmp section of radiusd.conf My config (for default virtual server) is: authorize { preprocess chap mschap suffix eap { ok = return } unix files expiration logintime pap } authenticate { Auth-Type PAP { pap } Auth-Type CHAP { chap } Auth-Type MS-CHAP { mschap } unix eap } preacct { preprocess suffix files } accounting { detail unix #radutmp attr_filter.accounting_response } # Session database, used for checking Simultaneous-Use. Either the radutmp # or rlm_sql module can handle this. # The rlm_sql module is *much* faster session { radutmp # # See "Simultaneous Use Checking Queries" in sql.conf # sql } post-auth { exec Post-Auth-Type REJECT { attr_filter.access_reject } } pre-proxy { } # # When the server receives a reply to a request it proxied # to a home server, the request may be massaged here, in the # post-proxy stage. # post-proxy { eap } I have tried it enabling and disabling radutmp in accounting section.

Hi Alan, I can achieve similar results through sudo and allowed exceptions, was just hoping for an easier and more straight forward approach with sudo root.

Re: rlm_perl and threads
by Sander Eerdekens 16 Nov '12

16 Nov '12

The old wiki used to contain more information on this. I'm currently in the process of making our rlm_perl module multithreaded as well. Some pointers: perl -V | grep -i multipl ... useithreads=define, usemultiplicity=define Compile-time options: HAS_TIMES MULTIPLICITY PERLIO_LAYERS check your multiplicity here. Multiplicity causes one perl process to be started, with multiple perl interpreters inside. Add a CLONE function to your perl script (yes, all in caps). The CLONE function is run every time a new perl interpreter is started. What happens is all existing variables are copied to the new interpreter when a new thread is started. In this function you can adjust values that should be unique for each thread (like database handlers). The number of threads are controlled trough the max_servers and max/min spare servers in your radiusd.conf Threading is not done in debug mode (-X), start your freeradius in normal mode to test multithreading. AFAIK the above information is correct and recent.

Pamd su client to proxy User-Name shows as root
by brad 16 Nov '12

16 Nov '12

Hi Everyone, Summary: trying to 2 factor from client to proxy to auth on sudo su -, su root. On client in pam.d/su: auth sufficient pam_radius_auth.so ruser debug On proxy radius -X shows: .. User-Name = "root" And it rejects it because the user "root" does not exist, but "Bob" who is sudo su'ing does. Is there a way to get the client to send the id of the person logging in through sudo su - to show as "Bob" rather than "root". Thanks, Brad
