configure freeradius to send no response if LDAP database fails
by Matthew Almen 02 May '18

02 May '18

Hello, I am trying to find out if there is a way to configure freeradius to exit or not send a response to queries if the local LDAP database becomes unavailable after the radius server is started. The radiusd service will not start if it cannot connect to the local LDAP database which I would expect. If I stop the LDAP service while freeradius is running I see from the debugging output pf /usr/sbin/radiusd -X that it fails to contact the LDAP server over and over and just keeps sending access-rejects back to our NAS router. Our router is configured to test the radius server with a test username but it will not mark the server as dead and move onto the next server in the server-group if it receives any response from the radius server. Even if an access-reject is received that still satisfies the test and the server does not get marked as dead. I need the server to be marked as dead if LDAP is down and radius is replying with an access-reject for everything. Any help would be appreciated. Thanks, Matt Here is radiusd -X output showing ldap failed and an access-reject being sent: rlm_ldap (ldap): Bind with cn=ldappkrv,ou=Polar,ou=Admins,dc=polarcomm,dc=com to ldap://localhost:389 failed: Can't contact LDAP server rlm_ldap (ldap): Failed to reconnect (1), no free connections are available (2) ldap: ERROR: Failed performing search: Can't contact LDAP server (2) [ldap] = fail (2) } # authorize = fail (2) Using Post-Auth-Type Reject (2) # Executing group from file /etc/raddb/sites-enabled/default (2) Post-Auth-Type REJECT { (2) attr_filter.access_reject: EXPAND %{User-Name} (2) attr_filter.access_reject: --> 9k-radius-test-username (2) attr_filter.access_reject: Matched entry DEFAULT at line 11 (2) [attr_filter.access_reject] = updated (2) } # Post-Auth-Type REJECT = updated (2) Delaying response for 1.000000 seconds [Description: MatthewAlmen]

Freeradius 3.0.16 behind NAT
by Bassem Mettichi 02 May '18

02 May '18

Hello, i am running freeradius 3.0.16 on Redhat 7.1 behind NAT, i have two servers keepalived + ipvsadm ande two servers freerdius, on keepalived iam using NAT when i test an accounting from a NAS i send request to the VIP but i get response directly from the radius server so recieved packet comes with source IP of freerdaius server and not the VIP, the nas rejected the packet: radclient: Received reply to request we did not send. (id=185 socket 3) the problem is i have the same architecture with freerdaius 3.0.4 and radclient same version and the NAS accepted the packet inspite source IP is for freeradius server and is not the VIP is there any difference between the two version on checking source IP packet? i would like the nas to ignore checking the source IP address of the packet is thsre any solution? Thanks in advance Mettichi Bassem

Can't get past first stage of authentication

Having set up a test VM and validated it with eapol_test, I am now moving to a live box with a real router. Again I have eapol_test working (if I use -aWAN_IP). I have my WAP at 172.22.22.2 and LAN interface as 172.22.22.1. Pretty much the only difference from the default installation is enabling ntdomain in sites-available/default and sites-available/inner tunnel and I've set up a local realm for CLEARSYSTEM in preparation for a domain login. Also ldap credentials have been set up. First I am trying a non-domain login with the user/pass I have checked in eapol_test but it is not getting very far: [root@microserver ~]# radiusd -X FreeRADIUS Version 3.0.13 Copyright (C) 1999-2017 The FreeRADIUS server project and contributors There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE You may redistribute copies of FreeRADIUS under the terms of the GNU General Public License For more information about these matters, see the file named COPYRIGHT Starting -

Chained intermediate certificate usage
by Sumant Gupta 01 May '18

01 May '18

Hi, I am planning to use chained certificates for my testing. So i am keeping all the certificates like Root Certificate/Manufacture/Sub-Manufacture certificate / device in the certs/ directory. I am setting auto-chain as yes. In 'eap' config file I am setting root.pem and device.pem . Where do I need to place the intermediate certificates.? Regards Sumant

How to determine the type of request? (EAP or not EAP)
by work vlpl 01 May '18

01 May '18

I have virtual site, that works with both EAP and not EAP request. In general case the main field, that used to query database or other storage is Username. EAP request usually has two identity anonymous and real. If user put in anonymous identity real username, that exists in database or users file. It can lead (in my case) to unexpected behavior. For example redirect request to home server. To handle this situation I added in "outer" virtual site the if clause like this authorize { chap mschap if (!&EAP-Message) { ... code that will be executed only for not EAP requests ... } eap pap } Is it safe to assume what all EAP request will have internal/real identity? Is there exists other better way to detect, (EAP request) what this Username is anonymous identity?

Access to the attributes lists in different sections
by work vlpl 30 Apr '18

30 Apr '18

Hello, I use rlm_python module to query information about supplicant from backend database and based on retrieved data decide what to do next with request. Also some of data retrieved from database go to a log. Some of requests are eap, and use inner tunnel virtual site. To prevent double log records (one from inner tunnel and one from "outer" virtual site) I do log operation (linelog module) only in "outer" virtual site. And pass necessary data from inner tunnel by using update outer.session-state { ... } I not use reply list, to store necessary data, because python module can set Proxy-To-Realm attribute and redirect some of request to home server (do proxy operation), and after received reply from proxy, freeradius server replace original reply with reply from home server. outer.session-state works for the most of cases, but not work for eap-ttls request, that will be proxied and rejected by home server. For example this is network config for eapol_test util network={ key_mgmt=WPA-EAP eap=TTLS identity="testing_remote" anonymous_identity="anonymous" phase2="autheap=MSCHAPV2" ... } Freeradius server configured to proxy only inner stage, after real identity is revealed. After the home server rejects the request, freeradius server clear session-state list in "outer" virtual site, and I can not access in in Post-Auth-Type REJECT section. To mitigate this I copy necessary data from session-state to control list in post-proxy section update control { Some-Attribute := &session-state:Some-Attribute } And control attributes list is available in Post-Auth-Type REJECT section. And this is basically works. My question is - Is there other way or attribute list, to store some data during full radius authentication session (until freeradius send Access-Reject reply), to be get able access to stored data from all sections (authorize, post-auth, Post-Auth-Type REJECT, pre-proxy, post-proxy etc.)? Or maybe there is a way to configure freeradius to not clear session-state list after Access-Reject reply from home server? -- Vladimir

Radius crashing with "Failed adding event handler for socket: Too many readers"
by Campbell McKenzie 30 Apr '18

30 Apr '18

Hello, I'm running Free Radius 3.0.16 on Redhat 7 and the about once or 10 times a day the service will "crash" (Exit with error code 1) with the error message "Failed adding event handler for socket: Too many readers". The only messages prior to Radius crashing are: Mar 19 21:37:34 radius1.acme.com radiusd[11344]: ... adding new socket proxy address 202.AA.BB.CC port 57158 Mar 19 21:37:34 radius1.acme.com radiusd[11344]: ... adding new socket proxy address 202.AA.BB.CC port 57158 Mar 19 21:37:34 radius1.acme.com radiusd[11344]:Failed adding event handler for socket: Too many readers Then systemd picks up the failure: Mar 19 21:37:34 radius1.acme.com systemd:radiusd.service: main process exited, code=exited, status=1/FAILURE Mar 19 21:37:34 radius1.acme.com systemd:Unit radiusd.service entered failed state. Mar 19 21:37:34 radius1.acme.com systemd:radiusd.service failed. Our configuration consists of about 157 home_servers (mostly running in auth+acct) and about 276 clients and two upstream proxies. (Eduroam). It seems like a new socket is created for each home_server (auth) + another socket for accounting and with such a high(?) number of home_servers we are running out of sockets (possibly). Is there a limit to the number of home_servers and/or clients?
