Re: Special WIFI Router MAC check for the user's first connection (Tom)

1 Sep 2011

      Arran,

 Thanks for your kind reply.

 It works.

 As you and Phil advised, I edit 2 files.

 /usr/local/etc/raddb/sites-available/default
/usr/local/etc/raddb/sites-available/inner-tunnel

 The script Phil wrote was put right after "sql" line.

 Thanks!

 Tom

Phil,
Thanks a lot for your great help.
I understand the scripts you wrote. But I don't know where I should put it in.
Can you please kindly advise which file I should edit?
/usr/local/etc/raddb/sites-available/default?
Yes in the authorize section, thats why the script is encapsulated within and authorize {} stanza :)

Phil - thanks for the feedback.
I just ended up proxying out to the IAS server usernames starting with
"DOMAIN\".
Ok. Obviously that will fail if enters their wireless credentials 
without a domain.

I configured the freeradius server to not support mschapv2 but will
support PEAP/GTC EAP/TLS.
It seems to be working fine with the Macs, iPads and Linux systems while
the windows systems are happy to talk to the IAS server.
It still bugs that ntlm_auth would not authenticate to the domain
controllers the challenge and nt-response.
I repeat: if you send debug info, people may be able to help.

I assume no one else is having any issues using ntlm_auth to W2008
servers? It may be some Windows GPO at our site for all I know.
Exactly which version of windows (2008 or 2008R2?) and at which 
functional level is your domain?
Did you try increasing the debug level for winbind using "smbcontrol" 
and then examining the debug logs after a failed auth?
For what it's worth, we have no problems with Windows 2008R2 domain 
controllers and the "samba3x" package available under RHEL5 (samba 
version 3.5.4-0.70.el5). We did have problems with earlier (Samba 3.3) 
versions after we'd upgraded to 2008R2 and upgraded functional level.

For example, WIFI AP 26, has the MAC address MAC26. I need ensure one
WIFI user, say user 58, must connect to WIFI AP 26 for the first time.
After the first connection, user 58 can connect to any WIFI AP in the
network.
Can someone give some advice on how to do it?
1. Create a whitelist of users who can authenticate to any AP using 
files, rlm_passwd or ideally SQL - see the FreeRADIUS wiki
2. If they are *not* found in the whitelist, check the 
"Called-Station-Id" attribute, which usually contains the MAC address of 
the AP. If your equipment uses a different attribute, check that.
3. If the AP MAC is the correct one, add the user to the whitelist, 
else reject
For example:
authorize {
...
  update control {
    Tmp-String-0 := "%{sql:select 1 from whitelist where 
username='%{User-Name}'}"
  }
  if (control:Tmp-String-0 == 1) {
    # user is in whitelist
  }
  elsif (Called-Station-Id == "aa-bb-cc-dd-ee-ff") {
    # user is connecting to the "whitelist" AP
    update control {
      Tmp-String-0 = "%{sql:insert into whitelist (username) values 
('%{User-Name}')}"
    }
  }
  else {
   reject
  }
  ...
}

Hello
Still trying to use freeradius with chillispot I still have problems
I'm trying to use mixed authentication
MAC addresses for some video devices in the "users" file
as follows :
00-06-F4-0D-08-66       Auth-Type := Local, User-Password == "xxxxxxxx"
                         Framed-IP-Address = 192.168.182.213,
                         Fall-Through = Yes
LDAP backend for "real" users at the end of the "users" file I have this 
statement
DEFAULT    Auth-Type = LDAP
     Fall-Through = 1
This configuration were working well on a very old debian machine which 
died suddenly
When I try to access the the chilli portal it ask radius for authentication
but it dows not work. See below the debug trace of radius daemon.
Help greatly appreciated, thank you.

That's pretty clear.  The NAS is sending a CHAP request.  You can't do
that with "Auth-Type LDAP"
Instead, list "ldap" in the "authorize" section.
Don't set Auth-Type.  It's almost always wrong.

Is it possible to rate users based on their data usage and reject
authentication to those users exceeding the limit ?
I think I can achieve rating using counter.conf and reading the usage from
radacct but not sure how to reject this user from authenticating when he
exceeds this usage limit ?
Thanks,
Shreya.
