Machine auth fails but user auth works
by Dennis Xu 09 Dec '15

09 Dec '15

I have FreeRadius 3.0.4 and authenticate to AD. My user authentication works but machine auth fails with certificate errors. I was using the same Windows 10 machine to test both scenarios. I attached the debug logs in both tests. What could be the reasons for the machine auth problem? Below are some of my configurations: mods-available/mschap: ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username=%{%{mschap:User-Name}:-00} --username=%{%{Stripped-User-Name}:-%{%{User-Name}:-None}} --domain=%{%{mschap:NT-Domain}:-CFS.UOGUELPH.CA} --challenge=%{%{mschap:Challenge}:-00} --nt-response=%{%{mschap:NT-Response}:-00}" mods-available/eap: default_eap_type = peap peap { tls = tls-common default_eap_type = mschapv2 copy_request_to_tunnel = yes use_tunneled_reply = yes # proxy_tunneled_request_as_eap = yes virtual_server = "inner-tunnel" # soh = yes # soh_virtual_server = "soh-server" # require_client_cert = yes } mschapv2 { # send_error = no } proxy.conf: realm LOCAL { } realm NULL{ } realm uoguelph.ca { } realm DEFAULT { authhost = prod1-east.eduroam.ca:1812 accthost = prod1-east.eduroam.ca:1813 secret = nostrip } Thanks!

Update username attribute in NAS
by Anirudh Malhotra 09 Dec '15

09 Dec '15

Hey Everyone, I have few questions first: Can User-Name attribute be updated at NAS after authentication is completed(post auth)? Second if yes how? Third I have tried sending username in update reply but it didn't change. I can see the radius sending it though. [sql] expand: INSERT INTO radpostauth (username, pass, reply, authdate) VALUES ( '%{User-Name}', '%{%{User-Password}:-%{Chap-Password}}', '%{reply:Packet-Type}', '%S') -> INSERT INTO radpostauth (username, pass, reply, authdate) VALUES ( 'anirudh', 'superchor', 'Access-Accept', '2015-12-09 10:48:49') rlm_sql (sql) in sql_postauth: query is INSERT INTO radpostauth (username, pass, reply, authdate) VALUES ( 'anirudh', 'superchor', 'Access-Accept', '2015-12-09 10:48:49') rlm_sql (sql): Reserving sql socket id: 3 rlm_sql (sql): Released sql socket id: 3 ++[sql] returns ok ++[exec] returns noop Sending Access-Accept of id 200 to 10.10.10.10 port 32769 User-Name = "anirudh" Finished request 4. Going to the next request Waking up in 4.9 seconds. PS: I am doing this to keep accounting from the sent username. Not the current username. PLEASE HELP! BR, Anirudh Malhotra

Accept eap-mschapv2 and proxy only mschapv2
by Jacob Julian 07 Dec '15

07 Dec '15

Hey all, Apologies if this is a commonly asked question, I did search and tried to mimic similar attempts. I'm looking to accept eap-mschapv2 auths and proxy only mschapv2 to another RADIUS server, which is set up to authenticate that user and return an Accept or Reject. My understanding is that this is easily accomplishable using FreeRADIUS. I have no prior experience with FreeRADIUS, so excuse any mistakes... This is the output of freeradius -X using RadEapTest on a remote machine, username Administrator. It seems that FreeRadius is attempting to auth the user instead of just proxying it along; this does work when I attempt a PAP connection from that same machine, it gets proxy'd through and auths just fine. Ready to process requests. rad_recv: Access-Request packet from host 172.16.201.10 port 63636, id=0, length=134 User-Name = "Administrator" NAS-IP-Address = 127.0.0.1 Calling-Station-Id = "02-00-00-00-00-01" Framed-MTU = 1400 NAS-Port-Type = Wireless-802.11 Connect-Info = "CONNECT 11Mbps 802.11b" EAP-Message = 0x020000120141646d696e6973747261746f72 Message-Authenticator = 0x67f16acfd64e0bf55afb823fbc79ce2f # Executing section authorize from file /etc/freeradius/sites-enabled/default +group authorize { ++[preprocess] = ok ++[chap] = noop ++[mschap] = noop ++[digest] = noop [eap] EAP packet type response id 0 length 18 [eap] No EAP Start, assuming it's an on-going EAP conversation ++[eap] = updated ++[files] = noop ++[expiration] = noop ++[logintime] = noop [pap] WARNING!

Freeradiusclient-1.1.7 and IPv6
by Alex Harrison 07 Dec '15

07 Dec '15

All,I hope I am using the right alias for this question. If this belongs elsewhere, I'll happily send it there, but I didn't want to disrespect the intent of the developer list if my question should be posted here. My question concerns whether the 1.1.7 release supports IPv6 addressing or if I misunderstand the release notes. For background, I'm utilizing the freeradius client library(1.1.7 tarball from the freeradius webpage) for a project I'm working on. The server side is set up and responds to radclient (both IPv4 and IPv6) requests properly. I'm trying to use the client library to talk over IPv6. First, I am using one of the included applications such as radiusclient or radlogin to establish a baseline to work with. When I try to send a radius request with one of these applications, I see in my system's log:rc_get_ipaddr: couldn't resolve hostname: feedThis would be for an address such as "feed:beef::17:18:20:10". Looking into the code, it appears that it is expecting IP:Port:Secret and it is parsing the first part of the IPv6 address as the whole address. Looking into the code on github, I see that there is a block in the source intended to deal with [IPv6]:Port:Secret form. I do not see this code in the 1.1.7 tarball. If I use the github code, I can successfully make IPv6 radius requests which is great and I can use. This brings me to my question, is the IPv6 release supposed to support IPv6 and I'm using it incorrectly or am I reading the release notes incorrectly? I see in the release notes: "Added support for IPv6. Patch from Nikos Mavrogiannopoulos." Browsing in the github repo, I see the commits from Nikos that add support for IPv6 along with the comment "Added support for connecting and listening to IPv6 addresses." This commit is from March and I can not find the associated code from the commit in the 1.1.7 tar ball I downloaded. Am I misunderstanding the release note or is IPv6 support I'm looking for actually not in the 1.1.7 release? Thank you for any help,Alex

Cleartext password does not match "known good" password
by Gang Li 07 Dec '15

Hi, I'm now running freeradius 3.0.10 + Mariadb on archLinux 4.1. It keeps telling me my password does not match the "known good"password. =================debug info=============== rlm_sql (sql): Released connection (1) (0) [sql] = ok (0) [expiration] = noop (0) [logintime] = noop (0) [pap] = updated (0) } # authorize = updated (0) Found Auth-Type = PAP (0) # Executing group from file /etc/raddb/sites-enabled/default (0) Auth-Type PAP { (0) pap: Login attempt with password (0) pap: Comparing with "known good" Cleartext-Password (0) pap: ERROR: Cleartext password does not match "known good" password (0) pap: Passwords don't match (0) [pap] = reject (0) } # Auth-Type PAP = reject (0) Failed to authenticate the user ======================================== I checked the database, in the radcheck table, I have one record: admin Cleartext-Password := 111111 In the radpostauth table, there's a Reject record, showing the username/password is exactly what I input: admin 111111 Access-Reject 2015-12-07 23:01:52 Since the two passwords are same, I just don't get why it reject me? What else should I do ? Thank you in advance. Gavin

Outstanding requests increasing until max_outstanding
by Louis Munro 07 Dec '15

07 Dec '15

Hello, I have a pair of FreeRADIUS (2.2.5) servers acting as load-balancers for a pool of authentication servers behind them that has been running flawlessly for about a year except for one thing. When I look at the list for my auth servers using radmin I get the following: radmin> show home_server list 10.0.0.100 1812 auth alive 150 10.0.0.101 1812 auth alive 223 10.0.0.102 1812 auth alive 130 10.0.0.103 1812 auth alive 114 Where I believe the last column is the number of outstanding requests for each home server (please enlighten me if I am wrong about that). Now the problem I have is that that last number (of outstanding requests) never goes down significantly. It fluctuates a bit during the day, but the trend is clearly up. This morning it was showing the following... radmin> show home_server list 10.0.0.100 1812 auth alive 140 10.0.0.101 1812 auth alive 220 10.0.0.102 1812 auth alive 109 10.0.0.103 1812 auth alive 114 And yesterday it was radmin> show home_server list 10.0.0.100 1812 auth alive 102 10.0.0.101 1812 auth alive 30 10.0.0.102 1812 auth alive 78 10.0.0.103 1812 auth alive 75 And last Friday one of the counters hit 65535 and all proxying to that home server stopped even though it was still responding (and was marked “alive”). I believe that counter is incremented once every time a request is proxied and (should be) decremented every time a reply is received or it times out. It does look though like there may be a case where the counter is not decremented. So my questions are: 1. Do I understand this correctly? 2. Is this a known issue? 3. If so, is it fixed in the latest of v2? or v3? 4. If it’s not an issue, what could I be doing wrong? I have no problem with the answer being “Upgrade” as long as I know that this is something that is indeed fixed in the version I’ll be upgrading to. These servers have performed so well up to now that I have not had a compelling case for upgrading. This could be just it.

rbtree in freeradius
by srithar jeevadurai 07 Dec '15

Hi Friends, I want to understand the rbtree data structure used in freeradius. my requirement is I have to store name-value pair in rbtree and I have to retrieve data base on name. As I understand from existing code. *declaration:* rbtree_t *conf= NULL; *creation: * rbtree_create( <1>, <NULL>, 0); 1-> function pointer to compare data for search 2-> NULL (I don;t know the purpose of 2nd parameter and 3rd parameter) 3->0 *Insert data:* struct data* temp={"Name", "Value"} rbtree_insert(conf, temp); *Search:* rbtree_finddata(conf, "Name"); *Delete:* rbtree_deletebydata(conf, "Name"); *compare function ( function pointer to compare data for search):* static int data_cmp(const void *one, const void two) { const data * data1 = (const data *) one; const data *data2 = (const data*) two; return strcmp(data1->name, data2->name); } -- Regards, Srithar Durairaj Alternate Mail I.D: srijeevadurai1(a)yahoo.co.in Mobile: +919886251852

LDAP Clients and Dynamic Clients on 3.0
by Peter Lambrechtsen 06 Dec '15

06 Dec '15

Hi Just looking at how the clients module works with the example config and Dynamic-Clients. Seems that Dynamic clients is loading the standard ldap group attributes. Any objections if I align the clients section of the ldap module and dynamic-clients with two options, either using standard schema and use the group object with the L and OU attributes for Password and shortname. Or using the radiusClient class. I'll also fix the doc/schemas/ldap/edir/freeradius-clients.ldif as that schema LDIF is busted and won't load into eDirectory. Cheers Peter

FR3.1.x head fails to build on RHEL 6.6
by Peter Lambrechtsen 06 Dec '15

06 Dec '15

Hello After downloading the head version of FR3.1.x it first complained that gcc was lacking C11, so I downloaded the devtoolset-2 rpms from RedHat devtoolset-2-gcc-4.8.2-15.1.el6.x86_64.rpm devtoolset-2-gcc-c++-4.8.2-15.1.el6.x86_64.rpm devtoolset-2-runtime-2.1-4.el6.noarch.rpm devtoolset-2-libstdc++-devel-4.8.2-15.1.el6.x86_64.rpm Now the configure succeeds with /opt/rh/devtoolset-2/root/usr/bin in the path, but when starting the make it fails to compile debug.c CC src/lib/debug.c /tmp/ccuawyBs.s: Assembler messages: /tmp/ccuawyBs.s:581: Error: expecting string instruction after `rep' make: *** [build/objs/src/lib/debug.lo] Error 1 Any idea what other dependencies I would need to upgrade (make?) to build on RHEL?
