Hello, How should settle in "radiusd.conf" max_request_time, cleanup_delay and max_requests? Currently I max_request_time = 30 cleanup_delay = 2 and max_requests = 50432 Is it set? If it is misconfigured what can happen? best regards

rlm_ldap + bind as user authentication
by Stefan Paetow 18 Jul '14

18 Jul '14

Hi, I'm trying to use FreeRADIUS with an LDAP oracle (to be precise, an OpenLDAP instance that uses SASL authentication). From what I understand, this should happen with a single-user bind to the OpenLDAP server... Since it's supposed to use a bind, I'm not retrieving the password, which at this point explains the 'no Auth-Type found'. Since Arran mentioned a while ago that binding with LDAP is a lot easier these days, is it correct that I use the following in my authorize section (after PAP): update control { # Only set the Auth-Type if it hasn't been set Auth-Type = LDAP } And then in the 'authenticate' section I use the below to enable binding? Auth-Type LDAP { Ldap } If that's all (plus the user search in .../mods-available/ldap), that's grand :-) Arran, can you confirm?

Conditional only returns False
by Bruno de Paula Larini 16 Jul '14

16 Jul '14

Hi, I'm trying to do an additional check for users contained on an Active Directory domain using information stored in a MySQL database. I'm using PEAP to check the users' credentials in the domain and that is working fine. The FreeRADIUS version is 2.1.12 on a CentOS 6. But when I add the following code after ntdomain in the file raddb/sites-enabled/inner-tunnel (I need the Stripped-User-Name), the check returns False even though the script output apparently matches the conditional. ntdomain if ("%{exec:/etc/raddb/scripts/user_check.py %{Stripped-User-Name}}" == "Accept") { update control { Auth-Type := "Accept" } } else { update control { Auth-Type := "Reject" } } Running the script manually with one argument shows the expected output. This is the output of radiusd -X ... [ntdomain] Looking up realm "NTDOMAIN" for User-Name = "NTDOMAIN\daniel.carrington" [ntdomain] Found realm "NTDOMAIN" [ntdomain] Adding Stripped-User-Name = "daniel.carrington" [ntdomain] Adding Realm = "NTDOMAIN" [ntdomain] Authentication realm is LOCAL. ++[ntdomain] returns ok ++? if ("%{exec:/etc/raddb/scripts/user_check.py %{Stripped-User-Name}}" == "Accept") Executing /etc/raddb/scripts/user_check.py %{Stripped-User-Name} expand: %{Stripped-User-Name} -> daniel.carrington Exec-Program output: Accept Exec-Program-Wait: plaintext: Accept Exec-Program: returned: 0 result 0 expand: %{exec:/etc/raddb/scripts/user_check.py %{Stripped-User-Name}} -> Accept ?

Thanks in advance!

RE: colourise doesn't seem to function.

Thanks Alan, > and you'd only get the coloured stuff when in full debug mode...which wouldnt be done on a production server unless you're also willing to patch? Ok, I'll try the update. It's funny because I'm sure I saw it working at one point early on, must have been an upgrade that broke it again. We do run -X (full debug) mode occasionally on production servers to find faults, given that NAS's tend to fail over to another radius if one fails.

Disconnect on Accounting Octet Quota
by Ali Jawad 16 Jul '14

16 Jul '14

Hi I did setup a max monthly quota check to limit the amount of B/W used by a user. The test worked, BUT only after a user disconnects and reconnects. While a user is connected he can go over limit and keep doing so. I did do some reading and obviously the reason is that in radacct acctinputoctets and acctoutputoctets are only set with a stop signal. Quote : This attribute indicates how many octets have been received from the port over the course of this service being provided, and can only be present in Accounting-Request records where the Acct-Status-Type is set to Stop. My setup is quite simple ,I do use the below. Now the question is , is there another approach to overcome this limitation ? Or can I force a Acct-Status refresh of some sort without disconnecting users ? sqlcounter daily-BW-counter { counter-name = Daily-Session-Octets check-name = Max-Daily-Octets reply-name = Session-Timeout sqlmod-inst = sql key = User-Name reset = daily query = "SELECT SUM(AcctInputOctets) + SUM(AcctOutputOctets) FROM radacct WHERE UserName='%{%k}' AND UNIX_TIMESTAMP(AcctStartTime) + AcctSessionTime > '%b'" }

colourise doesn't seem to function.
by Franks Andy (RLZ) IT Systems Engineer 16 Jul '14

16 Jul '14

Hi all, I'm running a not-particularly up to date version of FR - 3.0.0 git #aaa0ed5, and it's running on vmware. Neither the vmware console or putty sessions I'm running display with pretty colours any longer, I'm sure they used to. Colourise=yes is set in radiusd.conf and I'm running freeradius -X. Sorry for the noddy question, I don't mind being flamed if something obvious.. The main question is whether it's a known issue with that version, don't want to upgrade otherwise as these are in production. Thanks Andy

FreeRadius, block login after bad password
by Aurélien Muh 16 Jul '14

16 Jul '14

Morning everyones, After a lot of search, in books, net, friends, forums, ... I didn't find what I need. Here I explain my needs. (My FreeRadius version ==> 2.1.10 / On a Debian 6 ) My company ask me to block logins (users) after 3 bad password on the Radius. With all my research, I found the option "login Auth-Type := Reject", but this option can't be automatic, I had to use Fail2Ban to write in the "users" file, but unfortunatly Fail2Ban is working only with IP and not with login. So My last hope is coming from the you, because i'm so stuck with this ! I really thank you all of you for your future help ;-) Have a good day Aurélien,

Freeradius with daily counter
by Ali Jawad 16 Jul '14

16 Jul '14

Hi I did setup Freeradius with SQL backend and connected it to a l2tp vpn server. Connecting works great and accounting is logged into the radacct table. So far so good, now I am experimenting with limits. And I chose daily session time to test out first. I did insert into radcheck "where username is obviously test" test Max-Daily-Session := 100000000 When I did that, logon fails Now, here is where I might have messed up In sites-enabled/default I did uncomment authorise{ # Enforce daily limits on time spent logged in. daily and accounting { daily In radiusd.conf I did uncomment instantiate { # We add the counter module here so that it registers # the check-name attribute before any module which sets # it daily modules/counter includes counter daily { filename = ${db_dir}/db.daily key = User-Name count-attribute = Acct-Session-Time reset = daily counter-name = Daily-Session-Time check-name = Max-Daily-Session reply-name = Session-Timeout allowed-servicetype = Framed-User cache-size = 5000 } When I start radiusd -X I can see the following : radiusd: #### Instantiating modules #### instantiate { Module: Linked to module rlm_exec Module: Instantiating module "exec" from file /etc/raddb/modules/exec exec { wait = no input_pairs = "request" shell_escape = yes } Module: Linked to module rlm_expr Module: Instantiating module "expr" from file /etc/raddb/modules/expr Module: Linked to module rlm_counter Module: Instantiating module "daily" from file /etc/raddb/modules/counter counter daily { filename = "/etc/raddb/db.daily" key = "User-Name" reset = "daily" count-attribute = "Acct-Session-Time" counter-name = "Daily-Session-Time" check-name = "Max-Daily-Session" reply-name = "Session-Timeout" allowed-servicetype = "Framed-User" cache-size = 5000 } rlm_counter: Counter attribute Daily-Session-Time is number 11273 rlm_counter: Current Time: 1405421724 [2014-07-15 05:55:24], Next reset 1405486800 [2014-07-16 00:00:00] rlm_counter: Failed to open file /etc/raddb/db.daily: Permission denied /etc/raddb/modules/counter[71]: Instantiation failed for module "daily" What strikes me as weird is why does freeradius try to look in db.daily which does not exist, instead of the MySQL table radacct ? I did try to create a file db.daily "just for testing" and seLinux is disabled. [root@localhost raddb]# ls -lart /etc/raddb/db.daily -rw-r--r-- 1 root radiusd 0 Jul 15 05:35 /etc/raddb/db.daily [root@localhost raddb]# getenforce Disabled This is more or less a default CentOS RPM installation user and group are listed below user = radiusd group = radiusd Am I barking up the wrong tree here ? Any pointers in the right directions please? Regards

FreeRadius/NetMotion issue
by Levavi, Yariv 15 Jul '14

15 Jul '14

Hello, There's this environment of NetMotion which its authentication is through FreeRadius. I've made it work with EAP authentication and verify the configuration works. Then, I was asked to change the authentication to EAP-GTC (second authentication - Challenge/Response). I've made the necessary changes to eap.conf file (attached) but it seems that even though the FreeRadius is waiting for client's response, I don't get any login window in the client machine (only first login). I just wonder whether it is FreeRadius configuration or NetMotion's? Can you tell what is wrong?

24 hours after login not working
by Goke M Aruna 13 Jul '14

13 Jul '14

Thanks all, I am currently running FreeRADIUS Version 2.1.12, mysql version 5.1.73 I have set up counter.conf based on guide from http://lists.freeradius.org/pipermail/freeradius-users/2005-October/003506.… however, I noticed the counter just keep counting without terminating the user. my radgroupcheck is as follows: mysql> select * from radgroupcheck; +----+-----------+------------------+----+-------+ | id | groupname | attribute | op | value | +----+-----------+------------------+----+-------+ | 1 | validity | Max-Secs-Passed | := | 300 | | 2 | validity | Idle-Timeout | += | 300 | | 3 | validity | Simultaneous-Use | := | 1 | +----+-----------+------------------+----+-------+ 3 rows in set (0.00 sec) my counter.conf has the following: sqlcounter validity { counter-name = All-Secs-Passed check-name = Max-Secs-Passed sqlmod-inst = sql key = User-Name reset = daily query = "SELECT UNIX_TIMESTAMP(now()) - UNIX_TIMESTAMP(AcctStartTime) secs_passed_since_start FROM radacct WHERE UserName = '%{%k}' LIMIT 1" } an attribute called validity and I set Max-Secs-Passed to 300. however, I discover the query is not returning values in secs and I will like the user to spend only an hour a day and reset the counter the following day to zero for another 1 hour everday. Can someone assists?
