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 ?

FreeRADIUS exiting with Signal 11 on FreeBSD
by Hugh Blandford 27 Feb '12

27 Feb '12

I am running FreeRADIUS 2.1.10 on 64bit FreeBSD 8.1-RELEASE-p1 with LDAP auth and accounting records being sent to file and MySQL. I get the following in radius.log: Sun Dec 5 05:14:57 2010 : Info: Exiting normally. and the following in messages: Dec 5 05:14:57 cat kernel: pid 68292 (radiusd), uid 133: exited on signal 11 This has also occurred on two other occasions. I found somone else in the list archives who had a similar sounding problem on FreeBSD but there didn't appear to be an issue. Any suggestions as to what I can do to avoid this problem? Thanks, Hugh Blandford -- Hugh Blandford Island Internet ph 1300 130 428 mb 0412 016 875

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

Cannot control attribute ordering via "rlm_perl"
by Claude Brown 30 Jan '12

30 Jan '12

Hi, First, the version I'm using: # freeradius -v freeradius: FreeRADIUS Version 2.1.8, for host x86_64-pc-linux-gnu, [...] I'm trying to control the attribute-ordering when using "rlm_perl". Thus far my experience is that this is not possible. My theory is that this is due to the hash-tables used as the interface between the C and Perl worlds. Here is a small example that demonstrates the problem. I've turned on the "users" and "perl" modules in the authorize section (in that order). These are the important bits from the "users" file and the "example.pl" file. (from the "users" file) steve Cleartext-Password := "testing" Service-Type = Framed-User, Framed-Protocol = PPP, Framed-IP-Address = 172.16.3.33, Framed-IP-Netmask = 255.255.255.0, Framed-Routing = Broadcast-Listen, Framed-Filter-Id = "std.ppp", Framed-MTU = 1500, Framed-Compression = Van-Jacobsen-TCP-IP, WiMAX-Packet-Data-Flow-Id = 1, WiMAX-Service-Data-Flow-Id = 1, WiMAX-Service-Profile-Id = 2 (from the "example.pl") sub authorize { return RLM_MODULE_NOOP; } The debug log of the server is below. The interesting bits are (a) the "rlm_perl: Added pair" and (b) the attribute-order in the packet that the server sends in reply - the order is changed. The ordering is important to for me as I want those three WiMAX attributes packed inside a parent attribute "WiMAX-Packet-Flow-Descriptor". If I turn off the "perl" module (or place it before the "files" module) the packing works as expected. I put all this down to the attribute-list being rebuilt (by rlm_perl) from the %RAD_REPLY table. The hash-table has no concept of ordering, so it ends up randomised. The above is a contrived example - what I really want to do is add those three WiMAX attributes in my perl script. But due to the ordering problems I think I am wasting my time and need to come up with another solution. Can anyone see how I can control the ordering of attributes coming out of the perl script? Thanks, Claude Brown.
