Exec program debugging.

I am trying to execute a program in the post-proxy section on Access-Accept packets to bring up bandwidth management for a user when they log in: (radiusd.conf) exec bwup { wait = no; program = "/etc/raddb/bwlimit start %{User-Name} %{Calling-Station-Id} %{Tunnel-Private-Group-Id:0} %{NAS-Port} %{GLI-Rx-Data-Rate} %{GLI-Tx-Data-Rate}" input_pairs = reply packet_type = Access-Accept output = none } post-proxy { # post_proxy_log # attr_rewrite # attr_filter exec eap } However, the exec call keeps failing when called from inside radiusd -X: Ready to process requests. rad_recv: Access-Request packet from host xxx.xxx.6.99:1645, id=3, length=128 User-Name = "" Framed-MTU = 1400 Called-Station-Id = "00-13-19-36-C4-52" Calling-Station-Id = "00-13-D3-67-D7-05" Service-Type = Login-User Message-Authenticator = 0x43483d78f3b3f25bcb7657f1522050ef EAP-Message = 0x0202000501 NAS-Port-Type = Wireless-802.11 NAS-Port = 262 NAS-IP-Address = xxx.xxx.6.99 NAS-Identifier = "xxxx-Ch11" Processing the authorize section of radiusd.conf modcall: entering group authorize for request 0 modcall[authorize]: module "preprocess" returns ok for request 0 modcall[authorize]: module "mschap" returns noop for request 0 rlm_realm: No '@' in User-Name = "", looking up realm NULL rlm_realm: Found realm "NULL" rlm_realm: Adding Stripped-User-Name = "" rlm_realm: Proxying request from user to realm NULL rlm_realm: Adding Realm = "NULL" rlm_realm: Preparing to proxy authentication request to realm "NULL" modcall[authorize]: module "suffix" returns updated for request 0 rlm_eap: Request is supposed to be proxied to Realm NULL.

I am assuming I just have the configuration for this set up wrong or something. Obviously, the Access-Accept packet is not yet coming back because the first Access-Challenge hasn't even been passed on to the AP yet. So, I'm not sure why the post-proxy section even wants to fire the program at this point in the authentication process. Does anyone know what I did wrong? Thanks.

Backup/Primary Radius Config
by Maqbool Hashim 20 Mar '06

20 Mar '06

Hi, I have two radius servers one primary and one backup one, on different ip addresses. They both have a mysql backend which runs on the same physical machine. I need the sql database and radius configuration files to be synchronised periodically (probably every 24hours). I guess this is a common setup, so I'd appreciate some ideas as to the best way to achieve this?

General question about authentication/authorization
by Florian Prester 20 Mar '06

20 Mar '06

Hi, 1.) in the users-file, I can only check for attributes provided by the request - correct? 2.) in the users-file, if an entry matches all check-attributes, I can specify an Auth/Autz-Type - correct? 3.) in the users-file, if I do not specify the Auth/Autz-Type the radius is taken the requested Type automatically - correct? 4.) Authentication is comparing a password - correct? 5.) Authorization is even if a password is correct, the user may not use/do something - correct? 6.) Authorization is done by providing appropriate reply-attributes - correct? Now the big question: If I have an user who is authenticate, meaning correct username + password whereas the password is stored in LDAP. I want to replay attributes according th some other information stored in LDAP - how can I do such a thing, like: IF ldap-attribute::xy == valid_1 THEN RETURN ldap-attribute::IP-good, ELSIF dap-attribute::xy == valid_2 THEN RETURN ldap-attribute::IP-better, ELSE RETURN ldap-attribute::IP-bad Thanks Florian -- Dipl.

Authentication Question
by fvt3 20 Mar '06

20 Mar '06

Hi, I'm pretty new to freeradius and need some help. In Freeradius, when a request is made can you used the supplied userid and password to authenticate off from LDAP and if the user does not exist in LDAP can force it to authenticate off from the local database? If this is possible, can you direct me to some links that can further assist me. Thanks in advance ... __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

rlm_eap: identity does not match User-Name, setting from EAP identity
by Agent Smith 20 Mar '06

20 Mar '06

Hello group, I have FR configured for EAP/TLS for wireless but I ran into an interesting problem. When a user connectes, they are presented with a login box (username, password and domain name) if they put a domain name in the domain field, radius can't authenticate them and gives that error message. when the domain field is left empty, it works fine. I read some posting that talked about how you have to turn off ntdomain_hack off and I tried that, it didn't gave me that error but then the ntlm_auth failed saying 'NO SUCH USER' so my guess is that the user-name has to be exactly same as what gets sent into EAP message. has anyone else ran into this? any ideas on how to fix it? __________________________________________________ Do You Yahoo!?

Hi All, I am new to this free -radius usage, wanna setup radius on my company network for authentication and defining privilege level access on the network. I have gone through several mailing lists,docs on free radius site, whenever i issue authorization commands on the router i will be locked out on my NAS. I am using users file where i want simple authentication for few users and privilege level access. Error condition.... Rmcrad#show ver Command authorization failed. Here is the details . 1. radiusd -x radiusd -x Starting - reading configuration files ... Using deprecated naslist file. Support for this will go away soon.

Optimizing freeradius for very high loads
by Ashwin Gobind 20 Mar '06

20 Mar '06

Good day. I have freeradius running on a Dual P4 server with 4GB Ram. I am using freeradius to service clients. I require performance of 200tps. I am having a problem where many clients do not get responses for authentication messages. Monitoring my cpu and memory load during busy periods, my cpu max utilization is only 10% used, 90%idle. There is also enough memory. How can I optimize freeradius to increase the tps handling capability ? Thanks Ashwin Gobind �This e-mail is sent on the Terms and Conditions that can be accessed by Clicking on this link http://www.vodacom.co.za/legal/email.jsp "
