Fail to disable the Simultanous-use, somebody help me.

Hi, I've set up a freeradius server for Netscreen VPN with Mysql 5.0.22 and freeradius 2.0.5, and radiusd service is runing well, I can connect the VPN, and everything seems to be ok. But we have a unique need to allow more than 1 pc to login the VPN with the same username at the same time. So the Problem is ---only 1 pc can login, if another pc login with the same username, the previous connection will logout automaticly. This sounds kind of strange 'cause I use no simultaneous-use limitation, and the Netscreen share-limit has been set upto 1000. I tried the following ways to solve this problem, but failed. 1. I stop the freeradius acct port (1813) listen, I thought this might stop the acct information feed back to netscreen (NAS). But it turn out to be that nobody can login. 2. I setup simul-use control with sql query, and I create a usergroup in mysql, join the username into this group, and set the Simultaneous-Use as 5 in radgroupcheck table for this group. But only 1 person can login. 3. I Doubt That whether the radutmp limit the login, then i comment everything about radutmp in radiusd.conf, default.conf etc. But the things turn out to be the same. Then I stop the sql simul-query, but hte same. One strange thing: no matter what simul-query ( sql or radutmp) I use, both the radlast and the radacct table log the session. I'm wondering: Besides sql and radutmp, something is doing the simul-use verify job? So i don't know where i've done wrong. Hope someone can help out. here is the radiusd -X result: [root@localhost ~]# radiusd -X FreeRADIUS Version 2.0.5, for host i686-pc-linux-gnu, built on Aug 22 2008 at 16:32:02 Copyright (C) 1999-2008 The FreeRADIUS server project and contributors.

free RADIUS client + CHAP + PAM
by Vinay 20 Nov '08

20 Nov '08

Hi there There are a lot of places on the net which talk about how PAM cannot work with CHAP on the RADIUS server. Will an implementation of freeRADIUS client with CHAP and PAM(pam_radius_auth) module work? Please point me to the appropriate link. Thanks -Vinay

logging to stdout
by richard lucassen 19 Nov '08

19 Nov '08

I have already asked this question a few years ago, but it still seems to be impossible to log to stdout using Ubuntu's Freeradius-1.1.7 (I have worked around it by using a fifo) Am I overlooking something or is logging to stdout still an issue with 1.1.7? (for several reasons I'd like to stay with the original Ubuntu version) R. -- ___________________________________________________________________ It is better to remain silent and be thought a fool, than to speak aloud and remove all doubt. +------------------------------------------------------------------+ | Richard Lucassen, Utrecht | | Public key and email address: | | http://www.lucassen.org/mail-pubkey.html | +------------------------------------------------------------------+

ldap (sambaNtPassword) + peap-mschapV2 + freeradius : step by step question
by FM 19 Nov '08

19 Nov '08

Hello, I am trying to add a Wifi AP (aironet 1250). I am trying to use PEAP/MSCHAPV2 and SAMBA SambaNTpassword (LDAP Back-end). I read a lot of the question about the subject on the ML and cannot figure out all the steps. So here are all the steps I did : On the AP : I configured our radius server as the server manager. It thinks it is ok because the radius SRV receive request from it. for the AP I added a entry in clients.conf : client 192.168.4.8 { ipaddr = 192.168.4.8 shortname = wifi01 secret = mypassword } I edited the /modules/ldap : ldap { server = "localhost" identity = "cn=manager,dc=lan,dc=lexum,dc=pri" password = manager_password basedn = "dc=lan,dc=lexum,dc=pri" filter = "(uid=%{Stripped-User-Name:-%{User-Name}})" base_filter = "(objectclass=sambaSamAccount)" password_attribute = NT-Password I edited the ldap.attrmap (to map NT-Pasword to sambaNtPassword) : #checkItem LM-Password lmPassword #checkItem NT-Password ntPassword checkItem LM-Password sambaLmPassword checkItem NT-Password sambaNtPassword I DID NOT touch radiusd.conf I DID NOT touch /etc/raddb/sites-enabled/default I know that I need to enable ldap somewhere but ... where :D I will not post the result of -X because I know I need other config.

It required a local user account (set with a blank password). As to why it needs that, I have no idea, but thats that.

How to filter accountings based on the value of a VSA attribute
by cris miyata 19 Nov '08

19 Nov '08

Dear FreeRADIUS users, We configured FreeRADIUS to send accounting to 2 different servers, but for one of them I want to send only the accountings that have a VSA attribute equal to a give value. Does anyone know how to do this configuration? Thanks in advance. Regards, Cristina Miyata

ssh cleartext-password "? INCORRECT"
by David Ly 19 Nov '08

19 Nov '08

First of all let me say that I am using: FreeRADIUS Version 2.2.0, for host i686-pc-linux-gnu. I am trying to configure pam-radius-auth and freeRADIUS to allow users to ssh into a box and radius will appropriately match their permissions and etc. I've come across a problem that I am unable to solve, (I have a little over two months of experience with linux and even less with RADIUS and PAM) I have managed to get freeRADIUS running and I can do; 'radtest steve testing localhost 10 testing123' And i receive; Access-Accept packet from host 127.0.0.1 port 1812, id=114, length=71 Service-Type = Framed-User Framed-Protocol = PPP Framed-IP-Address = 172.16.3.33 Framed-IP-Netmask = 255.255.255.0 Framed-Routing = Broadcast-Listen Filter-Id = "std.ppp" Framed-MTU = 1500 Framed-Compression = Van-Jacobson-TCP-IP Now my problem occurs when I attempt to switch over to using ssh. I have configures the files; (The beginning of) /etc/pam.d/sshd auth required pam_env.so # [1] auth required pam_env.so envfile=/etc/default/locale auth sufficient /lib/security/pam_radius_auth.so debug @include common-auth ... And the matching shared secret for the server and pam_radius_auth.conf I've notices something in the logs which i have marked with '****'. Anyhelp is greatly appreciated. Here is the relavent part of the log from radiusd -X Using 'radtest steve testing localhost 10 testing123' rad_recv: Access-Request packet from host 127.0.0.1 port 58878, id=34, length=57 User-Name = "steve" User-Password = "testing" NAS-IP-Address = 127.0.0.1 NAS-Port = 0 +- entering group authorize {...} ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop [suffix] No '@' in User-Name = "steve", 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] users: Matched entry steve at line 76 ++[files] returns ok ++[expiration] returns noop ++[logintime] returns noop ++[pap] returns updated Found Auth-Type = PAP +- entering group PAP {...} [pap] login attempt with password "testing" [pap] Using clear text password "testing" [pap] User authenticated successfully ++[pap] returns ok +- entering group post-auth {...} ++[exec] returns noop Sending Access-Accept of id 34 to 127.0.0.1 port 58878 Service-Type = Framed-User Framed-Protocol = PPP Framed-IP-Address = 172.16.3.33 Framed-IP-Netmask = 255.255.255.0 Framed-Routing = Broadcast-Listen Framed-Filter-Id = "std.ppp" Framed-MTU = 1500 Framed-Compression = Van-Jacobson-TCP-IP Finished request 0.

And the matching shared secret for the server and pam_radius_auth.conf > .. > >> Using 'ssh steve@localhost' password: testing >> >> rad_recv: Access-Request packet from host 127.0.0.1 port 26561, id=106, >> length=83 >> User-Name = >> "steve" >> User-Password = "\010\n\r\177INCORRECT" **** >> >> > .. > >> WARNING: Unprintable characters in the password.

Also keep in mind that radtest works using the secret; "testing123". Sorry if I'm missing the point. Thanks for your help so far. David Ly -Soma Networks

attribute filter

Hi folk, I am using attribute filter on my radius proxy server to filter attributes (Tunnel-Type, Tunnel-Medium-Type, Trapeze-VLAN-Name=Tunnel-Private-Group-Id) received from the home server for multiple realms (authentification and authorisation attributes are stored in ldap database). Let's say for realm "dr4.cnrs.fr" I would like that only VLAN1 and VLAN2 are permitted. So I activated rlm_attr_filter and my attrs file contain this section: Service-Type == Login-User, Proxy-State =* ANY, . . . Tunnel-Type == VLAN, Tunnel-Medium-Type == IEEE-802, Trapeze-VLAN-Name == VLAN1, Trapeze-VLAN-Name == VLAN2, Tunnel-Private-Group-Id == VLAN1, Tunnel-Private-Group-Id == VLAN2, But It doesn't work unless I set those attributes to * ANY (Trapeze-VLAN-Name =* ANY, Tunnel-Private-Group-Id = * ANY, ...) Thanks for help and clues. -- Mustapha BOUIKHIF Service Systèmes d'Information CNRS - DR4 tel: +33 1 69 82 33 97 fax: +33 1 69 82 33 39
