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.

user-group for rejected users
by Fabricio Viana 21 Mar '17

21 Mar '17

Hello! Let´s suppose the following situations: 1) User exists but the password is wrong 2) User does not exist In both cases the answer is REJECT. It happens that certain hardware is making endless attempts that eventually saturating the server. - It is possible to cause the server, instead of rejecting the users, accept the login but responds ACCEPT with "framed-pool = pool-block" ? or/and - Is there any way to put REJECT users in a given group by default? Thanks! Fabricio

Huntgroup Checking
by simonm123 28 Feb '13

28 Feb '13

Am new to freeradius but have it mainly set up just fine. It's a fantastic tool and I'm enjoying using it :) Just one thing I'm struggling with is the huntgroups. I've followed the wiki to the letter and can see the server checking in the debug log. What I basically want to do is restrict users to certain networks, as per the wiki. If their huntgroup-name matches their huntgroup based on nasip, they can get online, otherwise they're rejected. I've put Huntgroup-Name = NetworkA in my radgroupcheck folder. In my radhuntgroup table, I have the nasip and groupname = NetworkA Then, in the authorize section of my default host, I put: update request { Huntgroup-Name := "%{sql:SELECT `groupname` FROM `radhuntgroup` WHERE nasipaddress='%{NAS-IP-Address}'}" } if (Huntgroup-Name == ''){ reject } All as per the tutorial In my debug log, if there is no match by IP, Huntgroup-Name is blank and the user is rejected. However, if the nasip address match but the name is different, the user is still allowed on. Do I need a more advanced query in the if section and if so,could you please advise what it should be Simon -- View this message in context: http://freeradius.1045715.n5.nabble.com/Huntgroup-Checking-tp4950385p495038… Sent from the FreeRadius - User mailing list archive at Nabble.com.

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 ?

Trying to do EAP-TTLS-PAP with CRYPT passwd in LDAP.. The tunelling seems fine.. but up to comparing the password it will failed. Refer below logs & config Some says (http://felipe-alfaro.org/blog/category/radius/) PAP is tunneled inside EAP-TTLS through EAP-GTC... Tried that as well.. still same error.. gtc { auth_type = PAP [even trying to change to LDAP/OCE - still same error) } Error ==== auth: type Local auth: user supplied User-Password does NOT match local User-Password auth: Failed to validate the user.

MSCHAPv2 followed by a smsotp authentication
by Thomas Glanzmann 08 Jun '12

08 Jun '12

Hello, I have a propiertary radius client which I want to authenticate against freeradius the following way: - User types is username: directory\Administrator password:secret - Freeradius authenticates against active directory. This already works - From the documentation of the propiertary radius client: After authenticating to RADIUS, you may get another prompt if the RADIUS server responded with a supported Access Challenge. Full generic RADIUS challenge/response is not supported, but a limited access challenge for a string token code is supported. - So now I want freeradius to send 'Access Challenge' and send a sms to the user (for that purpose I wrote a perl daemon which listens on a unix socket in order to talk to smsotp freeradius module)[1]. However nothing comes in. I configured freeradius the following way: sites-enabled/default: authorize { smsotp mschap } authenticate { mschap Auth-Type smsotp { mschap smsotp } Auth-Type smsotp-reply { smsotp } } users: DEFAULT Auth-Type = smsotp radius -X output here: http://thomas.glanzmann.de/tmp/radius-x.txt [1] smsotpd: http://thomas.glanzmann.de/tmp/smsotpd.pl And now my questions: - Is it possible to do a mschapv2 authentication followed by Access challenge in order to send out a sms with a one time password by configuring freeradius or do I need to code? Where do I find pointers? I read the source code of the smsotp and the rlm_example module, I get the basic idea that first the otp is generated and than it is checked, however I don't get how to configure freeradius to choose the codepath. I also don't get if it is possible to stack authentication methods in freeradius. Cheers, Thomas

Configuring freeradius for MACsec
by Matija Levec 03 May '12

03 May '12

Hello everyone, I'm trying to configure MACsec (per http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6638/de… ) in a test lab using cisco supplicant & switch and freeradius 2.1.12. Cisco docs say: "The CAK is delivered in the RADIUS vendor-specific attributes (VSAs) MS-MPPE-Send-Key and MS-MPPE-Recv-Key." "...authentication server sends an EAP key identifier that is derived from the EAP exchange and is delivered to the authenticator in the EAP Key-Name attribute of the Access-Accept message." With successful EAP-TLS authentication the Access-Accept message sent from freeradius looks like this: Sending Access-Accept of id 37 to 10.20.64.9 port 1645 Tunnel-Type:0 = VLAN Tunnel-Medium-Type:0 = IEEE-802 Tunnel-Private-Group-Id:0 = "123" MS-MPPE-Recv-Key = 0x84e5c624c3bcdeadca3c6210f24bd7b8336921ccc1c58399d397afc75770332c MS-MPPE-Send-Key = 0xa6c4860cc8092c251502f5adc3ee13586e05fe84cbbb8b6793b08d9523d12b1f EAP-Message = 0x03640004 Message-Authenticator = 0x00000000000000000000000000000000 User-Name = "user1" What should be configured for radius to also send EAP-Key-Name AVP? Kind regards, Matija Levec

Multi-valued LDAP attribute
by Adam Track 02 May '12

02 May '12

Hi All, In a continuation to my previous issue about how to reference an LDAP attribute in post-auth, I am now wondering how to iterate through a multi-valued attribute in a perl script I call from post-auth. In the debug you can see all three values are returned: ... [ldap] looking for reply items in directory... [ldap] personType -> Person-Type = "employee" [ldap] personType -> Person-Type = "fulltime" [ldap] personType -> Person-Type = "it" ... The perl module currently has the following code because I can't seem to be able to get any result other than the first, ie "employee", and I really need the other two (possibly more) to do a proper VLAN assignment: while (($att,$val) = each(%RAD_REPLY)){ if ($att =~ 'Person-Type'){ $count++; if ($count == 1){ $one = $val; } else { $two = $val; } } } $RAD_REPLY{'Reply-Message'} = "Total: $count, first: $one, second: $two."; The results are: ... Reply-Message = "Total: 1, first: employee, second: ." ... I'm no perl expert, but shouldn't I be able to reference all three values with $RAD_REPLY{'Person-Type'}? If not, where are the other values being stored? I read from the archives that this can be done with 3.X and foreach using unlang, but I'm stuck with 2.1.10 at the moment. Or, do multi-valued attributes need to be defined another way? Thanks, A.
