Hi all, I wish to configure 1 proxy radius server and 2 backend radius servers. One backend server is the real database for aauth and billing. The other one is inside a traffic shapper. I want to duplicate all accounting packets to this trafic shapper. After reading many times the proxy.conf and /sites-availables files, I can not forward all request to the traffic shaper until now. Does someone has a clear example for this kind of configuration? Regards. Emmanuel Rafaralahisoa Data Telecom Service.

Seqfault with multiple
by JDL 25 Mar '09

25 Mar '09

Hello to Alan and the rest of the list. I wanted to report this to the bug tracker but it appears to be down right now so I am sending it to the list. I had a situation where I needed to remove all of the attributes from a reply except for Service-Type to one specific client. Unlang seemed to be perfect for this. It should be as simple as the following. if (Client-IP-Address == "192.168.10.20") { update reply { Framed-Protocol == '' Framed-IP-Address == 0.0.0.0 Framed-IP-Netmask == 0.0.0.0 Idle-Timeout == 999 Session-Timeout == 999 Port-Limit == 999 Cisco-AVPair == '' Service-Type := Authenticate-Only } } However, when I try to do this, radiusd segfaults when attempting to run this block. I tried several tests and I could sometimes get up to two lines with "==" operators in an update block to work. However, adding more than two or three would cause a segfault. I was finally able to use the following workaround under 2.1.4. This workaround did not work under 2.1.3. if (Client-IP-Address == "192.168.10.20") { update reply { Framed-Protocol == '' } update reply { Framed-IP-Address == 0.0.0.0 } update reply { Framed-IP-Netmask == 0.0.0.0 } update reply { Idle-Timeout == 999 } update reply { Session-Timeout == 999 } update reply { Port-Limit == 999 } update reply { Cisco-AVPair == '' } update reply { Service-Type := Authenticate-Only } } My system is CentOS 5.2 32-bit. Hope this helps. Thanks, Jim L.

FreeRADIUS / ippool / Wireless
by Tim Gustafson 24 Mar '09

24 Mar '09

Hi, I'm using FreeRADIUS 2.1.3 on FreeBSD 7.1 to authorize users on my Cisco 1200 WAPs. I was wondering if it is possible to use ippools to assign client IPs rather than having them use DHCP, and I Googled around a bit and found a message that said this can't be done. I was curious if it can't be done because it's just something that fundamentally cannot work, or was it something that couldn't be done at the time, but perhaps can be done now or in the future? If it can't be done, I would love to hear any feedback people have about how to map wireless users to IP addresses. Has anyone else figured out a way to be able to record this kind of data without resorting to matching MAC addresses from the radius accounting records with data in a DHCP server log?

monitoring FR's EAP/PEAP capabilities...
by sth 24 Mar '09

24 Mar '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, Has anyone written code to test FR's EAP/PEAP functionality that would work with MS-CHAPv2? I see that 'radeapclient' will do MD5, but need to monitor FreeRADIUS talking to its oracle though rlm_mschap. Something that tested just MS-CHAPv2 would be fine, too, although it seems like rlm_mschap only ever exists inside EAP in the standard FR configs. I'm just looking to see if attempting to write something like this would constitute "reinventing the wheel". (FreeRADIUS 2.1.3 on RHEL 4.7; rlm_mschap modified to work with the unfortunately-named KCRAP[1].)

Windows Authentication and Authorization via LDAP on FreeRadius v 2.1.4 Configuration Help!!!
by Edwin Isada 24 Mar '09

24 Mar '09

Hello All, Excuse me for my lack of knowledge with Linux and FreeRadius. I hardly have any experience and I've been using version 1.1.3 for the past few weeks and had authentication working properly for Cisco devices. I decided to install the latest version 2.1.4 and forgot to save all my configuration for 1.1.3. Hopefully I'll learn my lesson next time =) The radiusd.conf file from what I recall looks totally different. I inserted my ldap information in the modules section, but running the basic debug I'm seeing an error "No authenticate method (Auth-Type). Even running the recommended radtest it's failing in reviewing the debug. I believe I'm missing authenticate config. If so do I need to modify another file or add it to radiusd.conf? I'm a little lost here if someone can point me the right direction and hopefully I can proceed with getting authorization working afterwards. Let me know if you need any additional information. I've added the debug info below. Another quick question has anyone configured this for F5 devices? rad_recv: Access-Request packet from host 127.0.0.1 port 1027, id=254, length=56 User-Name = "test" User-Password = "test" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 +- entering group authorize {...} ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop [suffix] No '@' in User-Name = "test", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] returns noop [eap] No EAP-Message, not doing EAP ++[eap] returns noop ++[unix] returns notfound ++[files] returns noop ++[expiration] returns noop ++[logintime] returns noop [pap] WARNING!

CHAP authentication issue
by Alan Cooper 24 Mar '09

24 Mar '09

I am trying to migrate from a working Freeradius 1.1.3 installation to a 2.1.x (currently trying .4) and I'm hitting problem getting CHAP authentication to work. I use the users file to authenticate DSL users via a Cisco LNS device - chap doesn't think it's getting the password from the users file in plaintext. My users file entry looks like this: # saf1975(a)lumisondsl2.co.uk ADSL: saf1975 Cleartext-Password = "mypassword", NAS-IP-Address = 193.29.223.253 Service-Type = Framed-User, Framed-Protocol = PPP, Framed-IP-Address = 84.19.252.194, Framed-IP-Netmask = 255.255.255.255, Cisco-AVPair = "ip:dns-servers=212.20.226.130 212.20.226.194", Cisco-AVPair += "ip:route#1=84.19.253.96 255.255.255.224 84.19.252.194", Cisco-AVPair += "ip:route#2=84.19.255.64 255.255.255.224 84.19.252.194", Cisco-AVPair += "ip:route#3=217.30.117.96 255.255.255.248 84.19.252.194" As I'm dealing with multiple domains, I strip out the domain names coming in from the LNS in proxy.conf. Can anyone explain why CHAP isn't getting a plaintext password and what I need to do to resolve? It appears to come through plaintext to the other 1.1.3 server...

modules instance name restrictions
by Thibault Le Meur 24 Mar '09

24 Mar '09

Hi, I recently came up with a small issue concerning modules instances name (especially when they set Auth-Type). * I defined my own pap module with the name 'pap-myorg' and expected it to set Auth-Type to PAP-MYORG, but in fact it wasn't setting the Auth-Type at all (moreover I saw no notice in the log about not beeing able to set the Auth-Type). * I changed the instance name to 'papmyorg' and now the module sets the Auth-Type to PAPMYORG. I tried to find in the doc where the restrictions on module instances names were defined, but didn't found any reference to this. And given the fact that some standard modules have specific chars such as '_' or '-', I thought there was little constraints. Is there any module instance naming convention written somewhere in the provided documentation (or online)? Maybe be it could be interresting to have a warning in the radius debug log in order to notice the administrator that Auth-Type wasn't set due to module naming restrictions? Best regards, Thibault

PAM-Radius authentication issue on Ubuntu 7.4: can not authenticate SSH users not present in /etc/passwd
by Hu, Fengliang (Procurve Networking) 24 Mar '09

24 Mar '09

Hi, I was trying to find a PAM-Radius mailing list and it seems that this is the best one. A Ubuntu 7.4 box needs to be configured such that SSH users will be authenticated against an external FreeRadius server. FreeRadius server version is 1.1.7-1build4. The Ubuntu box uses OpenSSH 4.3-p2 and /etc/ssh/sshd_config is set to "UsePAM yes". I downloaded PAM_Radius 1.3.17. Below is the procedure that I use Radius to authenticate a user in /etc/passwd (/etc/shadow doesn't have the password for that user). 1. FreeRadius server configures its clients.conf and user file to include a new user called "test1". 2. On my Ubuntu 7.4 box, add a user with command "useradd" to add a user "test1" but don't set a password. So the user "test1" on the Ubuntu box will be inactive. 3. Configure /etc/pam.d/ssh on the Ubuntu box to use "auth sufficient pam_radius_auth.so" 4. Also update the /etc/raddb/server on the Ubuntu box to point to the remote Radius server IP. 5. Try ssh test1@ubuntu box and it worked. Also monitored the Free Radius logging and it did show that the Access-Request packets went to Radius server. So step 1-5 worked well for me. Note that at step 2, the user account to be authenticated is added to /etc/passwd. The issue is: if step 2 is omitted, SSH login will fail. ACCESS_REQUEST packets with INCORRECT password were even sent to the Radius server. Further troubleshooting showed that PAM_Radius module got a bad password from PAM. I did some research from the website and some emails dated in 2006 said that PAM_Radius can only authenticate user accounts in /etc/passwd file. Is that right? Many thanks in advance, Feng

PAM module unknown
by Robert Svensson 24 Mar '09

24 Mar '09

Hi, I can compile the FreeRADIUS PAM module without any errors. But when I try to use it I always get a module unknown error. For example: AUTH-PAM: BACKGROUND: user 'john' failed to authenticate: Module is unknown This is how I compiled the module: gcc -fPIC -c pam_radius_auth.c gcc -shared -o pam_radius_auth.so pam_radius_auth.o -lpam What did I do wrong?
