Let FreeRADIUS ignore a request from rlm_perl
by Harm van Tilborg 09 Sep '15

09 Sep '15

Hey there, I'm using FreeRADIUS Version 2.2.8 and am wondering whether it is possible to ignore a request (i.e. send no reply at all) inside a rlm_perl module. I tried returning either RLM_MODULE_NOOP, RLM_MODULE_INVALID, RLM_MODULE_FAIL, and RLM_MODULE_HANDLED (without setting any reply attributes) inside an authenticate function. Although, in the end, they all result in the server rejecting the request, which is not what I want. How can I achieve this? -- Harm

Radius and MYSQL
by Alexandre Vilarinho 08 Sep '15

08 Sep '15

Hello all I'm new at Radius and I'm trying do configure Radius do authenticate the user from MYSQL databank. I configured the user in the user configuration file and it is working correctly, follow the configuration of the user. teste1 Cleartext-Password := "teste" Service-Type = NAS-Prompt-User, Cisco-AVPair = "shell:priv-lvl=1", Cisco-AVPair = "shell:cmd=show", Cisco-AVPair = "shell:cmd=show privilege" For this user I would like to configure a group in MYSQL called Privilege Level 1 and add it to that group. The Privilege Level 1 group should have the following configuration: Service-Type = NAS-Prompt-User, Cisco-AVPair = "shell:priv-lvl=1", Cisco-AVPair = "shell:cmd=show", Cisco-AVPair = "shell:cmd=show privilege" The user should have have the following configuration: teste1 Cleartext-Password := "teste" I've already installed MYSQL database and it is also integrated with Radius. I've followed the following explanation webpage tutorial - guide/SQL HOWTO I think that mysql databank and databases are correct and integrated with Radius. I didn't find any tutorial for beginners that explain step-by-step what should be done to configure the user group and the user. Can anyone explain to me how I can configure the user and the group? Regards Alex

ascend-data-filter in freeradius v3.0.x - interaction with RFC6929?
by Vereecke, Katrien (Katrien) 08 Sep '15

08 Sep '15

Hello, I am using the freeradius-server version V3.0.x and have the problem that the data specified in the users file for the Ascend-Data-Filter attribute (from the Ascend vendor space) is not correct sent in the radius access-accept msg. Is this related to the rfc6929 extended-attribute 242 that I need to do something specific, the Ascend-Data-filter is sent as part of the vendor space Ascend(=529), so there is no conflict with the 242 extended-attribute of rfc6929? My users file contains the following: Ascend-Data-Filter = 0x01010100010203040a0b0c0d05200600000504d2020200000000000000000000, The radius output is : (12) Sent Access-Accept Id 222 from 138.203.10.191:1812 to 138.203.10.123:64397 length 0 .... (12) Alc-Default-Router = 10.50.2.1 (12) Ascend-Data-Filter = 0x (12) Class = 0x41444d494e31 (12) Finished request Waking up in 4.9 seconds. (12) <done>: Cleaning up request packet ID 222 with timestamp +184 Ready to process requests My wireshark shows for the ascend-data-filter the following " 1a 28 00 00 02 11 f2 22 20 27 7a 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00" In a previous version of freeradius V2.1.12. this is working fine, but I stepped up to version V3.0.8 to have support for the radius extensions RFC6929. Thanks, Regards, Katrien.

unixODBC errors - undefined symbol:get_vtable
by Mohamed Imran (NBI) 08 Sep '15

08 Sep '15

Hi all, I've installed freeradius (built from source version: freeradius-server-3.0.9) on Centos 6.7 and am trying to get it to talk to our MS SQL servers (using unixODBC and FreeTDS driver) to lookup a mac address etc. as part of the post-auth process but not having much success. Running radius -X shows the following error: rlm_sql_unixodbc: 01000 [unixODBC][Driver Manager]Can't open lib '/usr/lib64/libtdsodbc.so' : ??vb??: undefined symbol: get_vtable rlm_sql_unixodbc: SQL down 08003 [unixODBC][Driver Manager]Connnection does not exist rlm_sql_unixodbc: Can't allocate the stmt rlm_sql_unixodbc: Socket destructor called, closing socket rlm_sql (sql): Opening connection failed (0) Has anyone else seen this issue? Any ideas on how this can be fixed? Also wondering if it's the version of unixODBC or FreeTDS im using is incompatible with this verison of freeradius. If so which version should I be using? Any help much appreciated. ================================ Environment details: ================================ OS: Centos 6.7 Freeradius: freeradius-server-3.0.9 [built from source as the repo version 3.0.3 kept throwing segmentation fault error] unixODBC: (from centos repo) Arch : x86_64 Version : 2.2.14 Release : 14.el6 FreeTDS: (from centos repo) Arch : x86_64 Version : 0.91 Release : 2.el6 ==================================== Regards, Mohamed Connect with us on: <https://twitter.com/NBIPComputing> The NBI Partnership Ltd provides non-scientific services to the <http://www.jic.ac.uk/> John Innes Centre, the <http://www.ifr.ac.uk/> Institute of Food Research, <http://www.tgac.ac.uk/> The Genome Analysis Centre and <http://www.tsl.ac.uk/> The Sainsbury Laboratory Disclaimer: This e-mail message may contain confidential information and is intended only for the use of the intended recipient(s).

Trigger EDIR-Intruder Lockout in FR3
by Anja Ruckdaeschel 08 Sep '15

08 Sep '15

Hi there, I wonder what is the designated way in FR 3.0.9 to trigger an eDirectory-Intruder Lockout with edir_autz=yes in addition? I want to use a, universal password retrieval b, grace login consumation, account expire check, password expire check, login time restrictions check, attribute checks, etc. c, intruder lockout trigger (I do a named ldap bind with the login-user with a password which is bad, if mschap rejects) in one radius config for PEAP/MSCHAPv2 with eDIR. So far, I only manage to get a and b OR a and c running. Perhaps you can give me a hint? Thank you for your time. Ciao Anja

rlm_sql and string escaping
by Unik 08 Sep '15

08 Sep '15

Hello list! I'm currently trying to port our custom GPL'ed FreeRADIUS module to 3.x. In addition to updating it to work on newer versions I tried to convert it from using our own half-assed SQL abstraction layer to rlm_sql's (using rlm_sqlhpwippool as an inspiration). While doing that I noticed that there are no DB-specific mechanisms to escape strings for use in DB queries (sql_escape_func is too strict and doesn't know about DB escaping rules). So my question is - is it ok for me to extend rlm_sql with DB-specific string escaping API, and if so, what are your suggestions and requirements for such an API? One thing to consider is that data-string-escaping and identifier -string-escaping follow different rules in several DBs. My current plan is: * Add another function pointer to rlm_sql instance (sql_string_escape_func). * Make it default to sql_escape_func. * Check if driver implements its own string escaping function, and if so, replace sql_string_escape_func with it. This implies that new function will have the same signature as sql_escape_func. -- With best regards, Alex Unigovsky mailto:unik@compot.ru Systems Administrator Maksim Co.

EAP - Anonymous - Proxying
by Vito A. Smaldino 07 Sep '15

07 Sep '15

Hi all, i'm a FreeRadius (and related auth protocols) newbie, my final goal is to join EDUROAM (!). I'm playing starting with a stock Ubuntu 14.04 + FR 2.1.12. Following http://deployingradius.com/ i succesfully tested EAP as explained here http://deployingradius.com/scripts/eapol_test/. Then i applied some changes to configs in order to forward requests for a specific REALM (generated by eapol_test using ttls-pap), to another FR (2.0 pre cooked using ZeroShell); it didn't work! Looking at the output of freeradius -X (attached), it seems that the problem comes from the "User-Name" field that contains the value assigned by eapol_test to the "anonymous_identity" field rather than that assigned to the "identity" field; then FR isn't able to select the right destination REALM because it doesn't known anything about the effective REALM. Things work if i put the destination FR IP Address in the DEFAULT REALM, but this configuration is not acceptable for me. I known that the EAP protocol uses a fake/anonymous identity during phase 1, but until now i'm not able to understand more than this :-( Any help and suggestion will be appreciated.

Dont know why Here is sites-available conf file and debug log: r authorize { update reply { Huntgroup-Name := "%{sql:SELECT groupname FROM radhuntgroup WHERE nasipaddress='%{NAS-IP-Address}'}" } preprocess chap mschap digest suffix eap { ok = return } files sql expiration logintime } authenticate { Auth-Type PAP { pap } Auth-Type CHAP { chap } Auth-Type MS-CHAP { mschap } digest unix eap } preacct { preprocess suffix } accounting { detail unix radutmp sqlippool exec } session { radutmp } post-auth { sqlippool reply_log exec } } pre-proxy { } post-proxy { eap } --SQL User and Group attributes: mysql> select * from radcheck where username like "tevfikceydeliler" -> ; +-----+------------------+--------------------+----+--------+ | id | username | attribute | op | value | +-----+------------------+--------------------+----+--------+ | 595 | tevfikceydeliler | Cleartext-Password | := | Test01 | +-----+------------------+--------------------+----+--------+ mysql> select * from radusergroup where username like "tevfikceydeliler" -> ; +------------------+---------------+----------+ | username | groupname | priority | +------------------+---------------+----------+ | tevfikceydeliler | UGR_Test_Wifi | 0 | +------------------+---------------+----------+ radgroupcheck is ; +----+------------------------------------+----------------+----+---------------------------+ | id | groupname | attribute | op | value | +----+------------------------------------+----------------+----+---------------------------+ | 48 | UGR_Test_Wifi | NAS-IP-Address | != | 10.1.1.71 | | 50 | UGR_Test_Wifi | Auth-Type | := | Reject | +----+------------------------------------+----------------+----+---------------------------+ --And debug log file is like that: rad_recv: Access-Request packet from host 10.1.1.75 port 24348, id=217, length=138 NAS-IP-Address = 10.1.1.75 NAS-Identifier = "fwguest.yasar.com.tr" User-Name = "tevfikceydeliler" User-Password = "Test01" Service-Type = Login-User NAS-Port-Type = Ethernet NAS-Port = 2000 Framed-IP-Address = 192.168.67.50 Called-Station-Id = "10.1.1.75" Calling-Station-Id = "c8:f7:33:38:20:ac" # Executing section authorize from file /etc/freeradius/sites-enabled/default +- entering group authorize {...} sql_xlat expand: %{User-Name} -> tevfikceydeliler sql_set_user escaped user --> 'tevfikceydeliler' expand: SELECT groupname FROM radhuntgroup WHERE nasipaddress='%{NAS-IP-Address}' -> SELECT groupname FROM radhuntgroup WHERE nasipaddress='10.1.1.75' rlm_sql (sql): Reserving sql socket id: 0 sql_xlat finished rlm_sql (sql): Released sql socket id: 0 expand: %{sql:SELECT groupname FROM radhuntgroup WHERE nasipaddress='%{NAS-IP-Address}'} -> PfSense ++[reply] returns notfound ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop ++[digest] returns noop [suffix] No '@' in User-Name = "tevfikceydeliler", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] returns noop [eap] No EAP-Message, not doing EAP ++[eap] returns noop ++[files] returns noop [sql] expand: %{User-Name} -> tevfikceydeliler [sql] sql_set_user escaped user --> 'tevfikceydeliler' rlm_sql (sql): Reserving sql socket id: 4 [sql] expand: SELECT id, username, attribute, value, op FROM radcheck WHERE username = '%{SQL-User-Name}' ORDER BY id -> SELECT id, username, attribute, value, op FROM radcheck WHERE username = 'tevfikceydeliler' ORDER BY id [sql] User found in radcheck table [sql] expand: SELECT id, username, attribute, value, op FROM radreply WHERE username = '%{SQL-User-Name}' ORDER BY id -> SELECT id, username, attribute, value, op FROM radreply WHERE username = 'tevfikceydeliler' ORDER BY id [sql] expand: SELECT groupname FROM radusergroup WHERE username = '%{SQL-User-Name}' ORDER BY priority -> SELECT groupname FROM radusergroup WHERE username = 'tevfikceydeliler' ORDER BY priority [sql] expand: SELECT id, groupname, attribute, Value, op FROM radgroupcheck WHERE groupname = '%{Sql-Group}' ORDER BY id -> SELECT id, groupname, attribute, Value, op FROM radgroupcheck WHERE groupnam e = 'UGR_Test_Wifi' ORDER BY id [sql] User found in group UGR_Test_Wifi [sql] expand: SELECT id, groupname, attribute, value, op FROM radgroupreply WHERE groupname = '%{Sql-Group}' ORDER BY id -> SELECT id, groupname, attribute, value, op FROM radgroupreply WHERE groupnam e = 'UGR_Test_Wifi' ORDER BY id rlm_sql (sql): Released sql socket id: 4 ++[sql] returns ok ++[expiration] returns noop ++[logintime] returns noop [pap] WARNING: Auth-Type already set.

Respond to DHCP Lease Query requests using rlm_cache
by Бен Томпсон 06 Sep '15

Hi Everyone I have configured FreeRADIUS to as a DHCP server which offers IP addresses based on the option 82 values added by a DHCP relay. In cases where the client sends a unicast renew request bypassing the relay, the option 82 values are queried from an instance of rlm_cache which have configured to keep a record of leases. (This replicates the option 82 "Stash" functionality in ISC DHCP Server). A bit of unlang is involved to check that the lease is valid and take care of clearing out the cache, but it is all fairly simple. The aformentioned server is working well, but I would also like it to be able to respond to Lease Query requests, and wondered if it would be possible to make it work in a similar way using rlm_cache. I would envisage that configuration might look something like this: dhcp DHCP-Lease-Query { # look in the cache to see if there is an active lease cache # check to see if we know about this IP ...some unlang lookup the IP from our usual auth source/DB ... ... some unlang to figure out if the lease(s) are valid, etc. ... # work out which type of reply packet is requred and add the relevant options if (result of above says lease is active) { update reply { DHCP-Message-Type := DHCP-Lease-Active ... add some other stuff to the reply... } } elsif (result of above says lease is unassigned) { update reply { DHCP-Message-Type := DHCP-Lease-Unassigned ... add some other stuff to the reply... } } elsif (result of above says lease is unknown) { update reply { DHCP-Message-Type := DHCP-Lease-Unknown ... add some other stuff to the reply... } } } I am guessing that the source code would need to be modified, and if so, it may be too much for me as I am not a skilled C programmer. I would be able to test it however. If it is possible without editing the code I would be grateful to find out how. Thanks Ben
