redback nas
by Alexandre Chapellon 19 Aug '09

19 Aug '09

Hello, This is not really an freeradius related question... sorry about that. Does anyone know about attributes supported by redback devices that would allow disconnection of sessions based on the amount of traffic transfered during the session and which could be set to higher than 4Gb? thanks to any redback guru! :)

So VERY True, Too many late nights and I really do appreciate your input as this gave me food for thought and I now have EVERYTHING Working. Both for Traffic & Session USAGE. For Usage, I still had to use Max-Monthly-Traffic as a Check := and based on sqlcounter calc, do a Reply = Sessions-Octets-Limit = XXXXXX on the Access-Accept as this is supported by the ppp 2.4.4 NAS. What I would like to know now, is how I can use sqlcounter to do a Month Calculation based on the date of the account being registered and NOT the Calander Month?

Freeradius authentication
by Rundzio, Remi 19 Aug '09

19 Aug '09

I am presented with a scenario where I need to run freeradius with no authentication (the system connecting to me is not sending credentials, just blindly sends data). Is it possible? When running the debug version of freeradius it does not require authentication for incoming streams but it seems to timeout at random times and shut down and a release version does not accept data without the sender authenticating. Thanks

segfault with regex and hint
by Alexander Clouter 19 Aug '09

Hi, It's that time of year to overhaul the cesspool that makes up my FreeRADIUS config files. I am running FreeRADIUS from git[1] about two days ago and found that by putting the following in my 'hints' file gives me the segfault shown below[2]. If I remove the end bit[3] then I do not get the segfault, but then I also do not get my comparison :) Any more information needed, then let me know.

How could I assing an IP a client.
by Rokkhan 19 Aug '09

I have tried to do this with a Sql user and setting Framed-IP-Address = 172.16.3.33 Framed-IP-Netmask = 255.255.255.0 values in radreply but i doesnt work. The client always take the IP from a DHCP server. I using freeradius 2.1.6 and validating wifi users with PEAP. The user validation works correctly. Thanks in advance.

Unlang Question/Problem
by Garber, Neal 19 Aug '09

19 Aug '09

I haven't had much sleep the past few days and just wanted another set of eyes on an issue I'm having. Also, I won't be able to do more testing until tomorrow (user/equip. unavailable) and wanted to try to fix it before then. I'm running FR 2.1.6 with patches to rlm_mschap & rlm_eap_mschapv2 to correct a problem with case-sensitive userids. Anyway, the patch was working great for user auth. and failing for machine auth. I used some unlang to get around the issue. I haven't done a lot with unlang (and yes I read the man page), so I may be missing something simple. I'm doing 802.1x authentication from Windows supplicant with PEAP/MS-CHAPv2. Here's the authenticate section of my inner-tunnel server: authenticate { Auth-Type PAP { pap } Auth-Type CHAP { chap } Auth-Type MS-CHAP { if (User-Name =~ /host\/(.*)\.energyeast\.net/i) { update request { Ntlm-Auth-Username = "%{1}$" } updated } else { update request { Ntlm-Auth-Username = "%{User-Name}" } updated } mschap-inner } Auth-Type LDAP { ldap } eap-internal eap-comodo } First, if I didn't include "updated" after the "update request" actions, then it would return reject. Is that normal (I didn't call a module in there)? Should the unlang be outside of the "Auth-Type MS-CHAP" block? Also, Ntlm-Auth-Username is expanded, there's a "[request] returns reject". I think this is the source of the problem, but I don't understand where the reject is coming from. The mschap module that follows returns OK, but the subsequent eap-comodo module returns reject with no explanation in the debug. Do I need something like: eap-comodo { ok = return } Here's the relevant debug output: Tue Aug 18 15:41:15 2009 : Info: Found Auth-Type = eap-comodo Tue Aug 18 15:41:15 2009 : Info: +- entering group authenticate {...} Tue Aug 18 15:41:15 2009 : Info: [eap-comodo] Request found, released from the list Tue Aug 18 15:41:15 2009 : Info: [eap-comodo] EAP/mschapv2 Tue Aug 18 15:41:15 2009 : Info: [eap-comodo] processing type mschapv2 Tue Aug 18 15:41:15 2009 : Info: [mschapv2] +- entering group MS-CHAP {...} Tue Aug 18 15:41:15 2009 : Info: [mschapv2] ++? if (User-Name =~ /host\/(.*)\.energyeast\.net/i) Tue Aug 18 15:41:15 2009 : Info: [mschapv2] ?
