Radius Accounting Counters
by Gilmour, Scott 14 Jan '14

14 Jan '14

Using Freeradius I would like to test Radius Accounting-Response Counters on my DUT. Specifically these counters: Radius Accounting Malformed Responses Radius Accounting Bad Authenticators Radius Accounting Unknown types Radius Accounting packets dropped Is there a tool or a way to modify what the server will send for a response in freeradius. This is specifically for testing purposes. Thanks Scott

Radius Server and Ldap Server
by 李亚坤 13 Jan '14

13 Jan '14

Hello all, I am trying to set up a radius server to perform authentication for wifi login against the user with password database in LDAP. I have no right to get the password back from LDAP, and the only reply information from LDAP server is the I login in success. However, I need to login wifi by a user name and password stored in LDAP server, without the reply password from LDAP, how can the radius server check whether the password I have provided is correct. I have tried many ways, but none of them work. I need help from you. Thanks. Best Regards Li

Freeradius DHCP problem with some vendors.
by Ricardo Oliveira 13 Jan '14

13 Jan '14

Hello, I am introducing the Freeradius as DHCP server at my ISP and am experiencing problems with some vendors specifically routers TP-Link. The FreeRadius allocates the IP Router but unable to associate the IP offered by freeradius, what intrigues me is that the problem does not occur with the ISC-DHCP. FreeRADIUS Version 2.2.4 (git #14e1ee7) Follow my configuration and Debug. server dhcp { listen { type = dhcp ipaddr = XXX.XXX.0.26 port = 67 interface = eth0 broadcast = no } dhcp DHCP-Discover { update reply { DHCP-Message-Type = DHCP-Offer } update reply { DHCP-Domain-Name-Server = XXX.XXX.0.6 DHCP-Domain-Name-Server = XXX.XXX.0.250 DHCP-IP-Address-Lease-Time = 120 DHCP-DHCP-Server-Identifier = XXX.XXX.0.26 } sql.authorize dhcp_sqlippool sql.post-auth ok } dhcp DHCP-Request { update reply { DHCP-Message-Type = DHCP-Ack } update reply { DHCP-Domain-Name-Server = XXX.XXX.0.6 DHCP-Domain-Name-Server = XXX.XXX.0.250 DHCP-IP-Address-Lease-Time = 120 DHCP-DHCP-Server-Identifier = XXX.XXX.0.26 } sql.authorize dhcp_sqlippool sql.post-auth ok } dhcp { reject } } Ready to process requests.

Hi, Just been looking at my development server logs and noticed Mon Jan 13 08:38:10 2014 : Auth: Login OK: [f5healthcheck] (from client f5-man-1 port 0 cli ) Mon Jan 13 08:38:13 2014 : Info: WARNING: Child is hung for request 13100 in component <core> module .

The other 2 aren’t. At this point FR is dead and had to be restarted. Not sure if I can reproduce the conditions but the server was last restarted on Friday.

post-auth bash script
by Jean Carlos Coelho 13 Jan '14

13 Jan '14

Hi! Is there some way to execute a shell with freeradius? here’s my scenario: - Users login to cisco wi-fi with 3 BSSID (teachers, students or employees) with LDAP credentials; - I verify if user is at group X, Y or Z (LDAP-Group); - *** Now, i need to verify in ldap (ldapsearch/shell) if the objectclass “userenalbled” is enabled or “expiredate” is “less” than "now” *** - Then grant or not access to wifi lan. This is what I did so far (eg. From students network)… Authenticate { post-auth { # if (LDAP-Group == “teachers" || LDAP-Group == “employees") { # reject # else { # noop # } # } } } Same file above: Authorize { update control { Auth-Type := `bash /opt/verify_date.sh '%{User-Name}'` } } Content of “verify_date.sh” file is an ldapsearch with filters to return the values of “expiredate” or “userenabled” with “if” statements to check the results, my question is: How can I work with the results of this script to allow or deny access to networks? Thank You!

Radius dies
by Tyller D 13 Jan '14

13 Jan '14

Hi, I have setup a new freeradius server and today it died for the first time. Some info regarding the install: Version: radiusd -v radiusd: FreeRADIUS Version 2.1.12, for host x86_64-redhat-linux-gnu, built on Oct 3 2012 at 01:22:51 Copyright (C) 1999-2011 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. OS CentOS release 6.4 (Final) Some notes on my setup: Everything runs through mod_perl. So my perl script handles the DB connection, add and removes records from the DB and so forth. Its called for each and every request. I checked the logs when the server was down and the errors I saw were Sat Jan 11 16:26:08 2014 : Info: WARNING: Child is hung for request 67332 in component <core> module <queue>. Sat Jan 11 16:26:12 2014 : Info: WARNING: Child is hung for request 67329 in component <core> module <queue>.

Sat Jan 11 13:19:04 2 Is there anything more I can do to troubleshoot and get more logs (exept run radiusd -X with nohup or something). Could it be my script causing this, or my DB or freeradius? Thanks for any advice

Trouble getting ldaps to work

Hi. I'm having trouble setting up a rlm_ldap module. FR version is 3.0.0 Trimmed output from radiusd -X: radiusd: #### Instantiating modules #### instantiate { } modules { # Loaded module rlm_ldap # Instantiating module "ldap_xxxxxx" from file /usr/local/etc/raddb/mods-enabled/ldap_xxxxxx ldap ldap_xxxxxx { server = "ldap.example.org" port = 636 password = "whocares" identity = "someuser(a)example.org" user { filter = "(sAMAccountName=%{%{Stripped-User-Name}:-%{User-Name}})" scope = "sub" base_dn = "dc=example,dc=org" access_positive = yes } group { filter = "(objectClass=posixGroup)" scope = "sub" base_dn = "dc=example,dc=org" name_attribute = "cn" membership_attribute = "memberOf" cacheable_name = no cacheable_dn = no } client { scope = "sub" attribute { identifier = "host" shortname = "cn" } } profile { filter = "(&)" } options { ldap_debug = 40 chase_referrals = no rebind = yes net_timeout = 3 res_timeout = 20 srv_timelimit = 20 idle = 60 probes = 3 interval = 3 } tls { ca_file = "/usr/local/etc/raddb/certs/ca.example.org.pem" start_tls = no require_cert = "demand" } } accounting { reference = "." } post-auth { reference = "." } rlm_ldap (ldap_xxxxxx): Initialising connection pool pool { start = 4 min = 2 max = 6 spare = 2 uses = 0 lifetime = 0 cleanup_delay = 5 idle_timeout = 60 spread = no } rlm_ldap (ldap_xxxxxx): Opening additional connection (0) rlm_ldap (ldap_xxxxxx): Connecting to ldap.example.org:636 rlm_ldap (ldap_xxxxxx): Bind with someuser(a)example.org to ldap.example.org:636 failed: Can't contact LDAP server rlm_ldap (ldap_xxxxxx): Opening connection failed (0) rlm_ldap (ldap_xxxxxx): Removing connection pool /usr/local/etc/raddb/mods-enabled/ldap_xxxxxx[8]: Instantiation failed for module "ldap_xxxxxx" FR is able to bind with the LDAP server only if require_cert is set to "never", which makes me believe this is a certificate verification issue. I tried to do a manual connect using openssl using openssl s_client -connect ldap.example.org:636 -CAfile /usr/local/etc/raddb/certs/ca.example.org.pem -debug which shows a Verify return code: 0 (ok) Module is being called at the sites-enabled/default: authorize { .... -ldap_xxxxx .... } BTW: Why the "-" before the module name? TIA

Problem setting up EAP-TLS with hostap
by Chris Anderson 12 Jan '14

12 Jan '14

Hi I am having a problem that appears to be similar to http://freeradius.1045715.n5.nabble.com/suddenly-problem-with-certificates-… but the solution there didn't work. I have configured hostap to use radius on a free radius server running locally. I am trying to use certificates for authentication. To test this I am using a stock android device, with the certicates generated from /etc/raddb/certs directory. The certs are installed on android and they appear to be correct. I have installed both the CA certificate and the client certififate on the device. When I run freeradius with the -X option I get the following log. I though that it might have been a fragmentation problem so I set fragmentation to 1024 in both hostapd and freeradius but I still get the same error. Cheers Chris

detail: suppress not working in 3.0.0?
by Stefan Winter 12 Jan '14

12 Jan '14

Hello, I am currently converting from v2 to 3.0.0 and want to preserve my old behaviour of logging packets using a "detail" instance without logging the User-Password. The 3.0 raddb template (mods-available/detail.log) seems to look exactly like the 2.x one; so I've created the following in /usr/local/freeradius/config/raddb/modules/auth_log_silent (yes, the directory is called modules, not mods-enabled, that is intentional and configured like that; radiusd loads that directory instead of mods-enabled. Please don't beat me up for it.) detail auth_log_silent { filename = ${radacctdir}/%Y%m%d/%{RESTENA-Service-Type}-service/auth-detail permissions = 0600 suppress { User-Password } } But during startup, "permissions" and the "suppress" section get ignored (filename is picked up though): # Instantiating module "auth_log_silent" from file /usr/local/freeradius/config/raddb/modules/auth_log_silent detail auth_log_silent { filename = "/var/log/radius/radacct/%Y%m%d/%{RESTENA-Service-Type}-service/auth-detail" header = "%t" permissions = 384 dir_permissions = 493 locking = no log_packet_header = no } And the log files do contain the User-Password attribute. I'm also staring at the "permissions" line and wonder if it ignores my 0600? Is the example in raddb/ incorrect?
