Hi, I think freeRADIUS supports RadSec by now, correct? https://wiki.freeradius.org/glossary/RadSec Best, Henning

External trigger for CoA
by Vadim Cargatser (vcargats) 14 Sep '20

14 Sep '20

Hi, We'd like to trigger a CoA based on an external event. Is this possible? There was a mail thread back in 2010 I was just wondering if something has been changed so far: http://freeradius.1045715.n5.nabble.com/Freeradius-COA-trigger-td3204376.ht… I know the basic approach is to use radclient for that scenario. Unfortunately, radclient does not support TLS/RADSEC which is critical for us. In case this is not currently possible, can we just implement that? Say to allow getting external events for example from RabbitMQ? Thanks, Vadim

hi there,I have freeradius version3 which has an external authentication script in the users file this is the users file content DEFAULT Auth-Type := accept Exec-Program-Wait="/usr/bin/php /var/www/html/cloudradius/captiveportal/auth.php \"%{User-Name}\" \"%{User-Password}\" \"%{Calling-Station-Id}\" \"%{NAS-Port}\" \"%{NAS-IP-Address}\" and this is the post auth section in default file under sites-enables post-auth { reply_log exec sql Post-Auth-Type reject { sql attr_filter.access_reject } } and this is the output which is returned from my external script in reject status Reply-Message="User not found" the problem is when I get rejected user it is not insert in radpost auth rable but it insert without any problem when I get accepted user this is the debug when I get rejected user (0) # Executing section post-auth from file /usr/local/etc/raddb/sites-enabled/default (0) post-auth { (0) reply_log: EXPAND /usr/local/var/log/radius/radacct/%{%{Packet-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/reply-detail-%Y%m%d (0) reply_log: --> /usr/local/var/log/radius/radacct/127.0.0.1/reply-detail-20200913 (0) reply_log: /usr/local/var/log/radius/radacct/%{%{Packet-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/reply-detail-%Y%m%d expands to /usr/local/var/log/radius/radacct/127.0.0.1/reply-detail-20200913 (0) reply_log: EXPAND %t (0) reply_log: --> Sun Sep 13 23:40:40 2020 (0) [reply_log] = ok (0) exec: Executing: /usr/bin/php /var/www/html/cloudradius/captiveportal/auth.php "28:C6:8E:3F:6E:dB1" "1234" "28:C6:8E:3F:6E:BB" "102" "103.81.214.233" "PPP" "192.168.0.1" "" "nas": (0) exec: ERROR: Program returned code (1) and output 'Reply-Message="User not found"' (0) [exec] = reject (0) } # post-auth = reject (0) EXPAND User : %{User-Name}, MAC : %{Calling-Station-Id}, Nas : %{NAS-IP-Address}, Nas Port : %{NAS-Port-Id}, Ip : %{Framed-IP-Address} (0) --> User : 28:C6:8E:3F:6E:dB1, MAC : 28:C6:8E:3F:6E:BB, Nas : 103.81.214.233, Nas Port : , Ip : 192.168.0.1 (0) Rejected in post-auth: [28:C6:8E:3F:6E:dB1/1234] (from client localhost port 102 cli 28:C6:8E:3F:6E:BB) User : 28:C6:8E:3F:6E:dB1, MAC : 28:C6:8E:3F:6E:BB, Nas : 103.81.214.233, Nas Port : , Ip : 192.168.0.1 (0) EXPAND User : %{User-Name}, MAC : %{Calling-Station-Id}, Nas : %{NAS-IP-Address}, Nas Port : %{NAS-Port-Id}, Ip : %{Framed-IP-Address} (0) --> User : 28:C6:8E:3F:6E:dB1, MAC : 28:C6:8E:3F:6E:BB, Nas : 103.81.214.233, Nas Port : , Ip : 192.168.0.1 (0) Login incorrect (exec: Program returned code (1) and output 'Reply-Message="User not found"'): [28:C6:8E:3F:6E:dB1/1234] (from client localhost port 102 cli 28:C6:8E:3F:6E:BB) User : 28:C6:8E:3F:6E:dB1, MAC : 28:C6:8E:3F:6E:BB, Nas : 103.81.214.233, Nas Port : , Ip : 192.168.0.1 (0) Delaying response for 1.000000 seconds Waking up in 0.2 seconds.

Add VSA in pre-proxy stage
by Arnaud LAURIOU 11 Sep '20

11 Sep '20

Hello, I'm trying to add a VSA in an Access-Request before proxing it to an authentification RADIUS server. I use this attribute definition : BEGIN-VENDOR FreeRADIUS format=Extended-Vendor-Specific-1 ATTRIBUTE FreeRADIUS-Eduroam-Prevent-Loop 1 integer END-VENDOR FreeRADIUS I add this VSA in the pre-proxy stage, but I get : (0) # Executing section pre-proxy from file /etc/freeradius/sites-enabled/default (0) pre-proxy { ... (0) if (!FreeRADIUS-Eduroam-Prevent-Loop) { (0) if (!FreeRADIUS-Eduroam-Prevent-Loop) -> TRUE (0) if (!FreeRADIUS-Eduroam-Prevent-Loop) { (0) update request { (0) &FreeRADIUS-Eduroam-Prevent-Loop := 1 (0) } # update request = noop (0) } # if (!FreeRADIUS-Eduroam-Prevent-Loop) = noop (0) ... skipping else: Preceding "if" was taken Why is the return state of this update to 'noop' ? I shoud not get a 'ok' or 'updated' return state ? And this VSA does not seem to be added to the forwarded Access-Request : (0) Proxying request to home server 194.57.4.197 port 1812 timeout 14.000000 (0) Sent Access-Request Id 255 from 0.0.0.0:47596 to 194.57.4.197:1812 length 162 (0) User-Name = "anonymous(a)renater.fr" (0) NAS-IP-Address = 127.0.0.1 (0) Calling-Station-Id := "02-00-00-00-00-01" (0) Framed-MTU = 1400 (0) NAS-Port-Type = Wireless-802.11 (0) Service-Type = Framed-User (0) Connect-Info = "eduroam.fr monitoring" (0) EAP-Message = 0x02c8001901616e6f6e796d6f75734072656e617465722e6672 (0) Message-Authenticator = 0x0705ffe079dfb7dc4cd3bdaad44477d4 (0) Event-Timestamp = "Sep 11 2020 15:14:17 CEST" (0) Proxy-State = 0x30 It seems that I missed something, but where ?

Linelog module sending message twice that has "warning" or higher severity level.
by Yiğit YAŞAR 11 Sep '20

Hi all, I have some issue with the linelog module. My "linelog" configuration as in below; *linelog {filename = syslogescape_filenames = nopermissions = 0600syslog_facility = daemonsyslog_severity = infoformat = "This is a log message for %{User-Name}"reference = "messages.%{%{reply:Packet-Type}:-default}"}linelog log_postauth {filename = syslogsyslog_facility = authprivsyslog_severity = infoformat = "User '%{User-Name}' authenticated via Radius"}linelog log_postreject {filename = syslogsyslog_facility = authprivsyslog_severity = warningformat = "User '%{User-Name}' authentication request rejected by Radius!"}* Also in "default" configuration file is like ; *post-auth {log_postauthlog_postrejectif (session-state:User-Name && reply:User-Name && request:User-Name && (reply:User-Name == request:User-Name)) {update reply {&User-Name !* ANY}}update {&reply: += &session-state:}-sqlexecremove_reply_message_if_eapPost-Auth-Type REJECT {-sqllog_postrejectattr_filter.access_rejecteapremove_reply_message_if_eap}Post-Auth-Type ACCEPT {log_postauth}Post-Auth-Type Challenge {}}* Problem is, when linelog sends log message with warning or higher severity, log message sending twice.There is no problem with info or lower severity level, they sending once. What could be the problem, do you have any idea? Thanks in advance Yigit

I need help or some guide!
by Ariel García Reyes 07 Sep '20

07 Sep '20

Hi I am implementing a Freeradius server to authenticate Wifi connections. I want to configure the authentication to be EAP-TLS and to be able to filter that the MAC of the device matches the authorized one stored somewhere, domain controller, database, file, etc., taking into account that a user could be authorized to use several teams. Thank you very much! -- ________________________________________________ Lic. Ariel García Reyes. GNU/Linux Registered User #357058

Proxying PAP to PEAP-MSCHAP-V2
by Xand Meaden 04 Sep '20

04 Sep '20

Hi, We have the following setup: 1. Linux servers using pam_radius module (which only supports PAP) for user authentication 2. NPS RADIUS servers which are configured to only support PEAP-MSCHAP-V2 Before I potentially waste too much time on something impossible - can FreeRADIUS be configured to accept incoming PAP requests, and then proxy them to NPS using PEAP-MSCHAP-V2? Thanks, Xand -- Xand Meaden | Senior Linux Engineer Faculty of Natural & Mathematical Sciences King's College London

Preventing proxy loops
by Arnaud LAURIOU 03 Sep '20

03 Sep '20

Hello, We have freeRADIUS proxies dedicated to eduroam, version 3.0.21. Some of our clients are sending us Access-Request ... with their realm. We forward them to their home_server (the same as the client) and they send them back to us again. This sometimes creates loops. How can we prevent our proxies from these loops ? Knowing that : - We don't have access to the clients/home server organizations RADIUS configs. - We tried a filter in the pre-proxy section : if (Realm && ("%{home_server:ipaddr}" == "%{client:ipaddr}")) { update request { &Module-Failure-Message += 'Rejected: loop prevent' } reject } But this rule is too strict for the monitoring requests used by some organizations. - Another way ? Regards, Arnaud Lauriou
