EAP TLS Server certificate error
by Thomas Manninger 23 Mar '20

23 Mar '20

Hi Mailing list, i installed freeradius on debian 9 for X802.1 authentication, which should replace an old freeradius server. For the new radius server, i generated a new CA for the client certificates and deployed the certificate on some clients. I also generated a certificate for the freeradius server (with the same CA): mods-enabled/eap: tls-config tls-common { certdir = ${confdir}/certs cadir = ${confdir}/certs private_key_file = ${certdir}/server.key certificate_file = ${certdir}/server.crt dh_file = ${certdir}/dh ca_path = ${cadir} check_cert_cn = %{User-Name} cipher_list = "DEFAULT" .. } When a client tries to authenticate, i get the following radius output: (7) auth_log: --> Mon Mar 23 15:42:14 2020 (7) [auth_log] = ok (7) if (!EAP-Message) { (7) if (!EAP-Message) -> FALSE (7) else { (7) eap: Peer sent EAP Response (code 2) ID 15 length 17 (7) eap: No EAP Start, assuming it's an on-going EAP conversation (7) [eap] = updated (7) files_x802_1_cert_auth: users: Matched entry XXXXXX at line 163 (7) [files_x802_1_cert_auth] = ok (7) } # else = updated (7) } # authorize = updated (7) Found Auth-Type = eap (7) # Executing group from file /etc/freeradius/3.0/sites-enabled/outer-tunnel (7) authenticate { (7) eap: Expiring EAP session with state 0x5b409518594a9812 (7) eap: Finished EAP session with state 0xfcae8891ffa18542 (7) eap: Previous EAP request found for state 0xfcae8891ffa18542, released from the list (7) eap: Peer sent packet with method EAP TLS (13) (7) eap: Calling submodule eap_tls to process data (7) eap_tls: Continuing EAP-TLS (7) eap_tls: Peer indicated complete TLS record size will be 7 bytes (7) eap_tls: Got complete TLS record (7 bytes) (7) eap_tls: [eaptls verify] = length included (7) eap_tls: <<< recv TLS 1.2 [length 0002] (7) eap_tls: TLS_accept: Need to read more data: SSLv3/TLS write server done (7) eap_tls: ERROR: System call (I/O) error (-1) (7) eap_tls: ERROR: TLS receive handshake failed during operation (7) eap_tls: ERROR: [eaptls process] = fail (7) eap: ERROR: Failed continuing EAP TLS (13) session. EAP sub-module failed But, when i replace the ${certdir}/server.key and ${certdir}/server.crt with the server certificate from the old server, x802.1 authentication works (why??) Can someone help me? Thanks!

Auth: Login incorrect: [maxx09/<no User-Password attribute>]
by Sam T 23 Mar '20

23 Mar '20

Hi freeradius community I have been working hard at making our already wonderful freeradius implementation also work with some VPN radius functions. A lot of this is a bit over my head, but i am grasping it as i go. So far, this server config works great for user/pass on PPTP, L2TP, OpenVPN, Soft-ether AAA but I am getting stuck with IKEv2. Ideally we can get ikev2 working on all devices, but it does require a lot of certificate work. I have been able to deal with the cert stuff from client, to router, and get the router to send the radius request, it comes back timeout. I tried it with also loading the cert chain in eap.conf but it didnt make a difference. i saw the <no User-Password attribute> in the radius.log either way. I think the issue is with something with the password being sent from the router, maybe it is hashed, maybe it is not sent, but this is what i see in the radius.log: Sun Mar 22 00:10:28 2020 : Auth: Login incorrect: [user123/<no User-Password attribute>] (from client wificpa port 0 cli 444.555.666.777) Any idea where i should dig, or what i should do to see why we see user123/<no User-Password attribute>? Is this the app not sending it, the router not sending it, or it arriving in some other attribute that radius is not listening for? (hashed, something specific for EAP?) I found that specifying the cert chain didnt make a difference when adding them in eap.conf, but here are some of those configs, and I will also include a -X: THANK YOU! Sam ############################################################################################################################################## I tried to trim this down some for readability and privacy...

pass parameters to rlm_perl script in a redundant setup
by Cornelius Kölbel 21 Mar '20

21 Mar '20

Hello, The redundant and redundant-load-balance setting is totally awesome. I would like to run perl modules in a redundant configuration. redundant { perl-auth-A perl-auth-B } With both being perl perl-auth-A { filename = /my/perl/script.pl } perl perl-auth-B { filename = /my/perl/script.pl } basically the same script but with two different configurations. So I am wondering how it is even possible to pass the information to the script, if it would run as "A" or "B". I could not figure to add some information maybe using update-control. So I am wondering if it is possible in some way to do perl perl-auth-A { filename = /my/perl/script.pl option = A } perl perl-auth-B { filename = /my/perl/script.pl option = B } Currently I need to create a copy of the perl script and do: perl perl-auth-A { filename = /my/perl/script-A.pl } perl perl-auth-B { filename = /my/perl/script-B.pl } Any hint is highly appreciated. I am running on FreeRADIUS 3.0.16. Thanks a lot Cornelius

MongoDB findAndModify() with aggregation
by Benjamin Thompson 21 Mar '20

21 Mar '20

Hi The findAndModify() method was recently updated to support aggregation. This means that the "update" parameter now accepts two different sytaxes: Old syntax (no aggregation): db.collection.findAndModify(query: { ... }, update: { ... } ) New syntax (with aggregation): db.collection.findAndModify(query: { ... }, update: [ ... ] ) The difference being that square bracket are used instead of curly bracktes for the aggregation pipeline. The first syntax works with FreeRADIUS but the second syntax gives the error: rlm_sql_mongo: 'update' does not hold a document. If there is any possiblitly to support the aggregation option then I think this would be very useful as it allows much more complex data processing inside the request. -- Ben Thompson

Strange Issue with datacounter_acct.sh

19 Mar '20

I am running FreeRADIUS 3.0.17. I have run into a strange issue with the *datacounter_acct*. It will run the *datacounter_acct.sh* only when it receives an *Interim-Update* packet from the NAS, and *NOT* when it receives a *Start* or *Stop* packet. What am I missing here? This is my datacounter_acct file: exec check_quota { wait = no program = "/usr/local/bin/bash /usr/local/etc/raddb/scripts/datacounter_acct.sh %{request:User-Name} %{request:Calling-Station-Id} %{request:NAS-IP-Address} %{request:Class} %{request:Acct-Status-Type} %{request:Called-Station-Id}" } This is a part of my default site: accounting { ... exec ... } -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Not setting Auth-Type (0) pap: WARNING: Authentication will fail unless a "known good" password is available Entry in "users" ( /mods-config/files/authorize symlink) file is updated testing Cleartext-Password := "password" users file is still a symlink. Any advice why the radiusd seems to be ignoring the users file? Thank you!

User and EAP authentication
by Thomas Manninger 18 Mar '20

18 Mar '20

Hi, i am using freeradius 3.0.12+dfsg-5+deb9u1 on a debian 9 server. I confiured two virutal servers, one for X802.1 network authentication (name: inner-tunnel), another virtual server with PAP username/password authentication (name: keycloak). Every incoming request should processed by the virtual_server "keycloak-auth", except all X802.1 request should be processed to the virtual_server "inner-tunnel". But all requests, also the X802.1 requests, are processed by the virtual_server keycloak. If i unterstand it correctly, the eap module should send all EAP requests to the inner-tunnel, but this in not working :-( ... Only if i send all requests to the inner-tunnel virtual-server, then X802.1 auth is working How can i fix the issue? My listen configuration: > listen { > type = auth > ipaddr = * > port = 0 > virtual_server = keycloak > } > listen { > type = acct > ipaddr = * > ipv6addr = :: > port = 0 > virtual_server = keycloak > } My keycloak size: > server keycloak { > authorize { > files > filter_username > filter_password > preprocess > expiration > logintime > keycloak > } > authenticate { > Auth-Type keycloak { > keycloak > } > Auth-Type pap { > pap > } > } > ... > ...

Initial setup error
by Farrell, Jolene 18 Mar '20

18 Mar '20

Hi FreeRADIUS, I am currently a new starter and first timer with building a RADIUS server. My ultimate goal is to set up a RADIUS server for only accounting purposes (storing CDR packets as flat files and then forwarding them to Splunk) but have run into a few problems following simple installation of the freeradius package. Upon running radiusd in debugging mode (following no changes made to the configuration files) I received the output attached at the bottom of the email (Error #1). I understand that this may have something to do with IPv6 compatibility, so I removed the “listen” sections listening for IPv6 addresses but this occurred in another error (Error #2) and I have struggled to find any documentation relating to this. I have also found little documentation on setting up and testing a FreeRADIUS server for accounting only purposes and was wondering if you could at all point me in the right direction? Error #1 [cid:image002.jpg@01D5FD1E.84A32BF0] Error #2 [cid:image004.jpg@01D5FD1E.84A32BF0] Jolene Farrell Graduate Network Software Specialist [/var/folders/jd/17dd5mm57fl5vdjmygpftn8w0000gp/T/com.microsoft.Word/Content.MSO/F5395A8E.tmp] This email may contain confidential information.
