Hi All, I’m hoping someone could assist me. Is it possible to deny/lockout users with the calling-stattion-id? I’m trying to lockout users connecting to my wifi with x connections a week from x called-stattion-id.

rlm_sql_null: No connections available and at max connection limit
by Artis Caune 03 Jun '21

03 Jun '21

Hi guys, We use rlm_sql_null for accounting and auth logs which allow us to respond quickly and defer inserts from regional nodes when db or link is down. Config is simple: accounting { ... sql_accounting } sql sql_accounting { driver = "rlm_sql_null" accounting { logfile = "${sql_write_dir}/accounting.sql" query = "INSERT INTO accounting ..." } } We get around 10-15 auth requests per sec and I don't see any errors for post-auth log. But we get around 180-200 acct requests per sec and I'm getting those errors for rlm_sql_null module: rlm_sql (sql_accounting): Cannot open new connection, already at max rlm_sql (sql_accounting): No connections available and at max connection limit README.rst says we can leave the pool definition or delete it for _null module. Wondering if there are some tweaks for the null module or it's a bug as there should be no max connection limit on this module ? Also noticed that null module tries to connect to radius table but no db_name is configured: rlm_sql (sql_accounting): Driver rlm_sql_null (module rlm_sql_null) loaded and linked rlm_sql (sql_accounting): Attempting to connect to database "radius" Why is it trying to connect to something if it should just append to logfile ? Thanks, Artis

Jun 3 16:21:38 radius systemd: radiusd.service failed. How to enable more verbouse debbug for rlm_perl or there is only way is to recompile rlm_perl with -g option?

Proxy and realm
by Andrés Gómez 02 Jun '21

02 Jun '21

Hi dear list I want to test a Freeradius v3 as a proxy to another freeradius. I have read documentation about proxy feature, so I have configured */etc/raddb/proxy.conf with something similar like this:* *realm office { type = radius authhost = 4.7.8.2:1812 <http://4.7.8.2:1812> accthost = 4.7.8.2:1813 <http://4.7.8.2:1813> secret = mysecret123 nostrip}* I have enabled realm modules on /etc/raddb/mods-enabled/ But when I try a simple user like: radtest user1@office password 127.0.0.1 1812 mysecret123 Freeradius takes "user1@office" like the username, it doesn't use the realm feature, so FR tries to find the user in Users file. What am I missing? Thanks in advance -- *C. Andrés Gómez R.*

But it is a lot friendlier to be able to collect all radius logs on radius server, isn'it? Thank you for the hint, Francesco

ARTICLE: How we made FreeRADIUS the best open source DHCP server
by Network RADIUS 02 Jun '21

02 Jun '21

** DHCP enhancements to FreeRADIUS 3 —————————————————————————————— As part of our contributions to the FreeRADIUS community, Network RADIUS took on the task of overhauling its DHCP support. The result is the same highly flexible and configurable DHCP server, but now easier to configure and outperforms both ISC and Kea DHCP in most common scenarios. And it’s available now, in FreeRADIUS 3.0.22 (https://freeradius.org/releases/) After running a battery of tests against ISC DHCP and Kea, we identified issues with FreeRADIUS that needed to be addressed in order to improve compliance as well as performance. We like to think that we understand network administrators pretty well. We know that performance is important, but it’s not the only consideration. In FreeRADIUS 3.0.22 we are excited to provide a DHCP server that: • Outperforms ISC DHCP and Kea • Has the flexibility to adapt to your network rather than the other way around • Implements query strategies that are optimized for the most common databases • Simplifies data workflow • Empowers real time monitoring In this post, we’ll provide a high-level overview of the changes we made and why, as well as the final performance results.

radmin 3.0.22 : 'stats client auth client_ip' needs a mandatory listen option ?
by Arnaud LAURIOU 02 Jun '21

02 Jun '21

Hi, Can you please confirm that with freeradius 3.0.22 radmin 'stats client auth <client_ip>' needs now the listen option for each client ? No more default value if this option is omitted ? Ex : radmin -e 'stats client auth <client_ip>' ERROR: No such client radmin -e 'stats client auth <client_ip> listen <my_ip> 1812' -> ok, got stats Regards, Arnaud -- Direction des Services Applicatifs RENATER - Rennes https://www.renater.fr/

Warning: Ignoring duplicate client
by George Chelidze 01 Jun '21

01 Jun '21

Hello, I am trying setup a sample dhcp server with freeradius 3.0.22. The same configuration is working fine with freeradius-3.0.12. The only difference is a warning at the end of server's startup: Ignoring duplicate client 10.0.0.0 There is just one entry in clients.conf: client x { ipaddr = 10.0.0.0/8 secret = xxxxxx } What else can be the reason for this warning? debug output: # /opt/freeradius-server/sbin/radiusd -X FreeRADIUS Version 3.0.22 Copyright (C) 1999-2021 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 -
