The NAS will *not* check the limit during a session, and the server can't check the limit during a session. So if they're under the limit at the start of the session, they can go over during the session, and no one will notice. This has NOTHING to do with changing the limits during a session. > 3. freeradius returns Session-Octets-Limit with the value from sqlcounter > which is the actual limitation. If the NAS supports this, it may work. But 99.9999% of the NASes do NOT support this.

I'd rather see a patch that works. Alan DeKok.

Client-IP-Address in detail files
by freeradius＠list.coretech.ro 20 Dec '05

20 Dec '05

hello, I have recently upgraded from CVS version as of 2005-02-19 with the one from 2005-12-17 and I no longer get the "Client-IP-Address" attribute in the files produced by the detail module. on the other hand the "Client-IP-Address" attribute is expanded correctly in sql querys. is there something different ? how can I add "Client-IP-Address" attribute back to the detail files ? and something else. where can I find the syntax of the "listen" directive ? (to remove bind_address and port directives) thanks, Razvan Radu

Problem with CHAP, users file and radclient
by Andreas Engler 20 Dec '05

20 Dec '05

Hello, i try to test a new freeradius (1.0.5) installation with radclient (Version 1.72.2.1)and an existing auth-log detailfile. The authentication failed in rlm_check_password. Please take a look at the radius.log sequence at bottom. In the auth-log file are accepted requests of a different server, wich gets the user-password via mysql. In the auth-log file are Chap-Password and Chap-Challenge attributes. The new installation should use the users file for storing the password. So i exctracted the data from mysql-db and created the users file. The passwords are stored cleartext. Did i somthing missing in the configuration (see log)? Couldn't i use radclient this way to test real packets? Did you need mor information? Thank you for help Andreas Engler the users file entry: hubba User-Password == "bubba", NAS-Port-Id == 1/0/0/8.32 the radius.log sequence: Thread 1 handling request 0, (1 handled so far) Framed-Protocol = PPP User-Name = "hubba" CHAP-Password = 0x2c98390c540135e0bbf1024d3dff4a71ef NAS-Port-Type = Virtual NAS-Port = 268959776 NAS-Port-Id = "1/0/0/8.32" Connect-Info = "pppoe4atm" Service-Type = Framed-User NAS-IP-Address = xxx.xxx.xxx.xxx CHAP-Challenge = 0x3fc1d8dc7b393459a292d664a9054a92 Processing the authorize section of radiusd.conf modcall: entering group authorize for request 0 modcall[authorize]: module "preprocess" returns ok for request 0 rlm_passwd: Added Grp-Name: 'test##all##' to request_items modcall[authorize]: module "etc_group" returns ok for request 0 radius_xlat: '/var/log/radius/radacct/127.0.0.1/auth-detail-20051220' rlm_detail: /var/log/radius/radacct/%{Client-IP-Address}/auth-detail-%Y%m%d expands to /var/log/radius/radacct/127.0.0.1/auth-detail-20051220 modcall[authorize]: module "auth_log" returns ok for request 0 rlm_chap: Setting 'Auth-Type := CHAP' modcall[authorize]: module "chap" returns ok for request 0 users: Matched entry DEFAULT at line 11 users: Matched entry hubba at line 31 modcall[authorize]: module "files" returns ok for request 0 modcall: group authorize returns ok for request 0 rad_check_password: Found Auth-Type CHAP auth: type "CHAP" Processing the authenticate section of radiusd.conf modcall: entering group Auth-Type for request 0 rlm_chap: login attempt by "hubba" with CHAP password rlm_chap: Using clear text password bubba for user hubba authentication. rlm_chap: Pasword check failed modcall[authenticate]: module "chap" returns reject for request 0 modcall: group Auth-Type returns reject for request 0 auth: Failed to validate the user.

Changing default reply from server when denied using Login-Time
by Drew S. Dupont 20 Dec '05

20 Dec '05

How can you change the default reply message sent back from the server when a user tries to login outside the allowed time? I am specifically asking about the message: Reply-Message = "You are calling outside your allowed timespan\r\n" that is returned when trying to login when using the Login-Time parameter for a user. I understand there is a "Reply-Message" field one can use in the user record. However, in our system it is only used when they are deactivated by the admin/manager and should not be populated otherwise. Is the only solution to recompile the freeradius server with that message changed? Or am I missing some param. or file where it could be changed? Thank you, Drew Dupont -- ------------------------------------------------------------------------------------------------------ Drew S.

hi everybody, well i'm trying to implement an ap over linux, i use madwifi-ng, debian sarge kernel 2.6.13 and freeradius supplied with debian installation cd's; i'd like to add more security so i decided to use hostapd and freeradius, first i generate my own certificates using openssl, and my hostapd configuration refer to freeradius files and directories;

Plain text password file
by Alexander Lund 19 Dec '05

19 Dec '05

Can somebody explain howto use rlm_passwd and a textfile with this setup: name:password:group and so on the order can be any way around, spaces can also be present. Any pointers will be gladly excepted. A sweet tutorial will result in a free night out in Borås, Sweden /Alex -- When there is no solution, there is no problem.

Freeradius RPM for SUSE 10.0 or 9.3
by LeRoy DeVries 19 Dec '05

19 Dec '05

Does anyone here on the list have the RPM for freeradius /w experimental modeles to share with me. I would be very greatfull. I would compile it however, SUSE won't let me compile the program because of interdependancy errors and it's like chasing my tail so I gave up. ---- LeRoy

pam_radius_auth

The pam_radius_auth README says "It allows ... password change requests." But the USAGE file says "Password changing is not implemented." That sounds contradictory.

UltaMonkey 3 and FreeRadius
by Hugues Lepesant 19 Dec '05

19 Dec '05

I all, I want to build a high availability radius plateform based on OpenSource software. To do so I've patched /usr/sbin/ldirectod with Matteo Bertato && Horms' patch found here http://lists.community.tummy.com/pipermail/linux-ha-dev/2005-September/0116… It works fine, I make the load balancing for both auth [1812] and accounting [1813]. But I've a strange behavior when freeradius started as daemon, server are nerver enabled for auth by ipvsadm. I must start freeradius in debug mode (-X) on the radius server to be enabled by the load-balancers. Even if I can make some successfull radtest from the load-balancers, and the log of ldirectord seems to be ok. I'm not sure it's UlraMonkey fault, I have tested with the last freeradius version and it the same :( Does any one have anye idea for where it can come from ? Best regards, hugues Distrib Debian sarge Freeradius 1.0.2-4 and 1.0.5 from source ultramonkey 3-1um.1 ipvsadm 1.24+1.21-1 Kernel 2.6.13.4 -- Hugues Lepesant ---------------------- Ingénieur Exploitation VeePee Tel : +33 1 73 02 68 02 119 rue de Paris 92772 Boulogne Cedex FRANCE
