Using libkqueue, how stable it is with freeradius 3.x?
by work vlpl 15 Jun '23

Hi, I want to try to use freeradius 3.2.x which is compiled with libkquueue. In my tests, it is working fine. But I also see the list of know issues https://github.com/mheily/libkqueue/blob/master/BUGS.md of libkqueue and just want to double-check if I should not use it. But I hope that since freeradius 4.x by default will use it the library integration is fine and the listed issues are not affecting freeradius 4.x or 3.x. Best regards, Vladimir

DHCP Radius proxy (IPv4 and IPv6)
by Ľudovít Mikula 09 Jun '23

09 Jun '23

Hi all, I have a relay-agent which does only DHCP and is not capable of talking to RADIUS server (using auth/acct). However the requirement is to be able to use freeradius with it for the additional functionalities and configurability, over both IPv4 and IPv6. The "authentication" should be done only by checking Option82 circuit-id/remote-id against configured user in freeradius. What are the options for configuring it over IPv6? Probably some dhcp to radius proxy able to do message conversion like: DHCP Discover/Solicit -> RADIUS Access-Request RADIUS Access-Accept -> DHCP Offer/Advertise What would be the best approach to handle this use case (unfortunately I cannot change the hardware). Regards -- Ludo Mikula

EAP-TLS unable to get local issuer certificate
by MH 08 Jun '23

08 Jun '23

Hello, I am trying to setup EAP-TLS and I am getting radius server error "eap_tls: (TLS) OpenSSL says error 20 : unable to get local issuer certificate", "send TLS 1.2 Alert, fatal unknown_ca" Test client is wpa_supplicant 2.1 built on Ubuntu Linux 22.04.2. All tests are done locally on FreeRadius server 3.2.3 (Ubuntu Linux 22.04.2) When I test "client.crt" with "openssl verify ./client.crt" I get "OK". Specifying -CAFile OpenSSL parameter with chained CA cert also produces "OK". All CA certificates (there is also an intermediate certificate) are in /etc/freeradius/certs, /etc/freeradius/certs_eaptls and also /usr/lib/ssl/cert. One certificate per file. FreeRadius's EAP-TLS stanza is cadir = ${certdir}/certs_eaptls private_key_file = ${certdir}/rad.key certificate_file = ${certdir}/rad.crt auto_chain = no Server and client certificates are signed by different commercial CA. All certificates have intermediate CA. eapol_test config file for EAP-TLS is network={ key_mgmt=WPA-EAP eap=TLS identity="blabla(a)domain.tld" ca_cert="/etc/ssl/certs/chain.crt" client_cert="client.crt" private_key="client.key" private_key_passwd="blabla" } AppArmor disabled. Permissions for all certs are r--r--r-- (at least). OpenSSL rehash done. I have no idea what could be wrong.

rlm_perl module crash on high load, need to restart service
by Imdad Hasan 05 Jun '23

05 Jun '23

Thanks Alen, Great if the perl or any module will provide async support. Right now I am using FreeRADIUS version 3.0.20 with Jan-2023 built. Actually I tried loading with Jmeter, it's handling around 300 requests per second, but sometimes the resend ratio is big compared to my last exec module php script.. Even the new perl module and php swoole back-end is very light weight with Async MySQL support. But I don't know why the resend ratio is more than the old exec module. I am using 2Core CPU/1GB RAM EC2 for new code for FreeRADIUS with perl module and php swoole backend. The MySQL server is in the same VPC with different EC2. Please guide me for a quick solution for now, after FreeRADIUS 4.x, i will upgrade it. Thanks Imdad

Hi All, I am using the rlm_perl module with an async TCP server. in this rlm_perl module is the TCP socket client and swoole is Async TCP socket server. When i am testing high load, at that time it's showing an error duplicate packet conflict module queue and crashes the server, even after stopping the load the freerdius is not working, i need to restart the freeradius server and it's working fine. Please guide me. Thanks Imdad

Hi, have anybody tried to do a static build of radiusd binary? Would it be possible with current build setup? If so, can you share the steps to get a static build (or with as little dynamic dependencies as possible). Thank you. -- Ludo

Modifying outgoing device name attribute
by Kenny Simpson 02 Jun '23

02 Jun '23

Hi all, New to freeradius and need a little help which has stumped me and a colleague. We are using freeradius to proxy authentication from Fortinet to freeradius to cisco acs. We are now stumped on how to get it to authenticate properly. We can see in the Cisco ACS logs that the device is being authenticated and that it is matching the appropriate access service but it is failing on shared secret even though we know that the shared secret is correct and that the password for the user is correct. Looking at the logs its says that the client is the incoming proxy server with its name and ip address as this is what is in the client. It has the NAS IP correctly defined but I am thinking that because the device name and ip are different to the NAS IP then its failing as the actual proxied connection has a different secret. Is there anyway of modifying the out going "device name attribute and ip" to match that of the client configuration. I hope this makes sense hahah Thanks Kenny
