DHCP relay IP and gateway IP, possible bad logic?
by Igor Smitran 05 Mar '13

05 Mar '13

In case when freeradius is talking to a DHCP relay it should *always* send answears to a initiating relay IP. But, it doesn't. Cisco CMTS is using 10.10.10.1 as his giaddr for all requests made by CM's, MTA's and CPE's. All replies should go to 10.10.10.1. But, currently, if CPE gets public IP 200.200.200.2 with gateway 200.200.200.1, freeradius tries to send reply to 200.200.200.1 instead of 10.10.10.1. This is my opinion, maybe i am wrong...

Simultaneous Use strategy
by Mehdi Ravanbakhsh 04 Mar '13

04 Mar '13

Dear All I need to do some change in Simultaneous use check strategy . In fact when a user is disconnecting by physical reasons and the session is not get stop ( in heavy load of user i should set NAS type to other ) and the user can not connect again because of Simultaneous Use limitation. So i put some script in crontab to check radacc table and find any session that not get update (*intermediate) then stop that session .* * * * * *in this case because of **Delay period in **checking** dead session , user can not connect until cron script detect dead session .* * * *So i need to change **Simultaneous Use check strategy and if user with same Calling Station ID - NAS ip address - NAS port - Called station ID try to connect i need to accept it .* * * * * *i just find some query in sql.conf about **Simultaneous Use.* * * *Is there any way to change Simultaneous Use configuration?* * * *Best regards.* * *

Replicate accounting packets to multiple servers
by Shreya Shah 04 Mar '13

04 Mar '13

Hi, How can I replicate accounting packets to multiple servers when I have only one realm ? I have setup replicate and replicate-to realm in accounting section and also home_server and pool in proxy.conf but replication only works for the first home server. It wouldn't replicate accounting to the other server. This is how my proxy.conf config for replication looks. home_server remote_server { ipaddr = x.x.x.x port = 1813 type = acct secret = testing123 } home_server col_server { ipaddr = x.x.x.x port = 1813 type = acct secret = testing } home_server_pool remote_pool { type = fail-over home_server = remote_server } home_server_pool col_pool { type = fail-over home_server = col_server } DEFAULT { Replicate-To-Realm := remote } realm remote { acct_pool = remote_pool acct_pool = col_pool } I just see the replication accounting packets being sent only to remote_server and not to col_server. Thanks, Shreya.

Using return-output from external script as reply-message
by Stefan Kuegler 04 Mar '13

04 Mar '13

Hello. I want to use an external script (multiotp) for authentication in FreeRADIUS. I created a new module called multiotp that starts the external script... exec multiotp { wait = yes input_pairs = request output_pairs = reply program = "/etc/freeradius/multiotp/multiotp.php -log -debug '%{User-Name}' '%{User-Password}'" shell_escape = yes } ...and activated this module in the authentication-section of the default-configuration (and also in the inner-tunnel-configuration): authenticate { [...] Auth-Type MultiOTP { update reply { Reply-Message = "Hello, %{User-Name}" } multiotp } [...] } The external script gives me additional informations (like "OK: Token accepted", "INFO: Authentication failed" etc.) after authentication. When I run freeradius in debug mode, I can see the output-message from the external script: [...] Exec-Program output: 0 OK: Token accepted Exec-Program-Wait: plaintext: 0 OK: Token accepted Exec-Program: returned: 0 ++[multiotp] returns ok Login OK: [test] (from client localhost port 0) [...] Is it possible to use this output-message as the reply-message ? Thanks. Stefan P.S.

Problem Using GoDaddy Wildcard Certificate
by Thomas Simmons 04 Mar '13

04 Mar '13

Hello All, I'm trying to get my setup working with a GoDaddy-issued wildcard certificate (I understand self-signed is recommended). I don't understand why this is not working and appreciate any input. What I have found so far: Everything works with self-signed certs. With the CA cert imported, "Validate server certificate" is not required. Everything works with GoDaddy certs on Android. Everything works with GoDaddy certs and "Validate ..." unchecked. On Win 7, with "Validate ..." checked, I receive the following error: [peap] Length Included [peap] eaptls_verify returned 11 [peap] <<< TLS 1.0 Alert [length 0002], fatal access_denied TLS Alert read:fatal:access denied [peap] WARNING: No data inside of the tunnel. [peap] eaptls_process returned 7 [peap] EAPTLS_OK [peap] Session established. Decoding tunneled attributes. [peap] Peap state ? [peap] FAILED processing PEAP: Tunneled data is invalid. [eap] Handler failed in EAP/peap [eap] Failed in EAP select ++[eap] returns invalid Failed to authenticate the user. The GoDaddy certs appear to have the necessary "XP Extensions". The following is reported under "Enhanced Key Usage" when I view the cert in Windows: Server Authentication (1.3.6.1.5.5.7.3.1) Client Authentication (1.3.6.1.5.5.7.3.2) Likewise, openssl reports: $ openssl x509 -in server.crt -text -noout | grep "Web Server" TLS Web Server Authentication, TLS Web Client Authentication The certification path for my cert is: My Cert > GoDaddy Secure Certification Authority > Go Daddy Class 2 Certification Authority I added my certificate to the beginning of the chain file provided by GoDaddy (used cat to ensure no errors) and pointed certificate_file to this. I then selected the "Go Daddy Class 2 Certification Authority" under the network profile. When this did not work, I imported the chain file into my Trusted Root CAs and selected "GoDaddy Secure Certification Authority" in the wifi profile. This also did not work. Lastly, I cleaned up my certificate store, split apart the chain file into separate files, imported "GoDaddy Secure Certification Authority" into my Trusted Root CAs, selected the same in the wifi profile, and pointed certificate_file to my cert ONLY. Does anyone see a reason this should not work? Ideas on what to try next? Thank you.

Trucation of octet attribute handled by rlm_perl
by Бен Томпсон 01 Mar '13

01 Mar '13

Hello everyone I am having a slight problem with rlm_perl and I would really appreciate any advice/help. I have a perl script which rlm_perl adds a value to the DHCP-Classless-Static-Route attribute something like this :- #### perl script snippets ############ ... my $route = pack('C7', split(/\,/, "16,172,16,10,0,0,2")); ... &radiusd::radlog(RADLOG_DEBUG, "packed data: " . unpack('H*', $route)); ... $RAD_REPLY{'DHCP-Classless-Static-Route'} = $route; ... ############################### ..but from the debug output I see that the attribute data is truncated at the first octet with value 00 :- ### freeradius -Xx snippets ######## ... Thu Feb 28 10:35:23 2013 : rlm_perl: packed data: 10ac100a000002 .... Thu Feb 28 10:35:23 2013 : Debug: rlm_perl: Added pair DHCP-Classless-Static-Route = ??? ... DHCP-Classless-Static-Route = 0x10ac100a .... ############################## Am I doing somthething daft, or is this a possible bug in rlm_perl? I am using freeradius 2.2.0.

[Help] - How To configure Radius timeout / count retries
by Danny Kurniawan 01 Mar '13

01 Mar '13

Hi All, Let say for example in our Wireless AP (access point) we can put 2 Radius server in sequence, radiusA and radiusB. I know the AP will eventually look at the 1st server, and if its not available (let say server is down) then it will go to the 2nd radius server (I only assume this). So is there any way in Radius conf we can set the retries or timeout, so for example after failed for 2 times (no matter what is the error is) it will goes to the other radius server? Thanks Danny -- Best Regards, Danny
