sql failover doubt
by Francesco Cristofori 01 Aug '07

01 Aug '07

Hi all, I set up sql failover using the "redundant" feature as stated in the documentation, but I still have a doubt. When I start freeradius if all mysql backend servers are up everything goes fine. If one server is down, radiusd complains because it is unable to create the corresponding module: is there a way to avoid this behavior? Thanks in advance, Francesco Cristofori.

Re: Freeradius as a proxy to Windows IAS - reserved characters in shared secret?

Hi I've just been doing some research on the net and found this link on the GNU radius client reference page: http://www.gnu.org/software/radius/manual/html_chapter/radius_13.html#SEC262 It looks as if the radtest client has reserved characters. Does anyone know if this applies to shared secrets with the Freeradius server as well??? Thanks Clive

Dear all, I have successfully configured freeradius and posgtgresql sql according to doc that is in freeradius bundle. My cisco vsa is also inserted in the database. Now the problem here is how to retrieve the data from the database. Is there any pre-made front end of this kind of things? I need to calculate daily/weekly/monthly voip CDR. One more thing can i insert my syslog cisco CDR to above database? thanking you, regards, nik --------------------------------- Ready for the edge of your seat?

Brilliant Thanks Claudia :-))) Putting the shared secret in single quotes 'se\cret' in radclient and in double quotes with the backslash escaped in clients.conf and proxy.conf "se\\cret" worked fine with the radtest and what's more this now works too: Linux VLE <----------->FreeRadius<------------>Microsoft IAS Thank-you !!!

Be careful with character escaping and bash cli (always use single quotes to pass to radtest what you want). Also avoid ${foo} as a secret client 127.0.0.1 { secret = "\044{prefix}" } radtest gigi kent 127.0.0.1 1 '/radiusd' => OK!! ($prefix = /radiusd) client 127.0.0.1 { secret = "\\testing123" } radtest gigi kent 127.0.0.1 1 '\testing123' => OK radtest gigi kent 127.0.0.1 1 "\testing123" => OK (because bash does not expand \t) radtest gigi kent 127.0.0.1 1 "\\testing123" => OK (because bash expands \\t to \t) radtest gigi kent 127.0.0.1 1 '\\testing123' => NOT ok client 127.0.0.1 { secret = "$\[" } radtest gigi kent 127.0.0.1 1 '$[' => OK client 127.0.0.1 { secret = "$\\[" } radtest gigi kent 127.0.0.1 1 '$\[' => OK Have fun!

Hi, I am trying to establish EAP-TLS communication. My client having certificate ( rsauser1(a)abc-inc.com) sends HELLO to free radius, via a pass through server having IP address 172.25.13.61.

Re: Freeradius as a proxy to Windows IAS - reserved characters in shared secret?
by clive gould 01 Aug '07

Hi Thanks once again for all the advice :-) Does anyone know if there some characters that are reserved i.e cannot be used in secret keys with a freeradius server. If so what are they? I've been experimenting with the radtest client and the freeradius server using local unix validation with interesting results. 1) If I use a secret key (16+ characters and the same key in both the radtest client and freeradius clients.conf) that contains pure alpha characters the key is accepted and authorisation is successful. 2) If I use a secret key (similar to the one set on the IAS server) containing characters such as $\[ then the key is rejected and authorisation is unsuccessful. I have tried enclosing the key in single and double quotes, but the key is still rejected. Hopefully getting nearer to a solution... Thanks very much Clive

Radius proxy: Assertionfailed problem
by Janne Peltonen 01 Aug '07

01 Aug '07

Hi! I seem to be getting errors such as Tue Jul 31 11:50:23 2007 : Error: Assertion failed in request_list.c, line 1012 in my Radius logs from time to time, especially during high load. This assertion failure leads to Radius server getting stuck, which in turn results in my clients getting stuck... My Radius server functions solely as a proxy to an another server. Any suggestions would be greatly appreciated. Cheers, --Janne Peltonen -- Janne Peltonen <janne.peltonen(a)helsinki.fi>

Hi everyone Thanks for all the help and advice so far :-) I have installed freeradius 1.1.7 and get the appended message when I try to use it as a proxy between a Linux/Moodle/PHP radius client and a Windows IAS server. The shared secrets are definitely the same. The Linux/Moodle/PHP radius client authenticates directly with the Windows IAS server without any problems, but it will not authenticate with the freeradius proxy in between! I need a working freeradius proxy. Help...

Adding a NAS via SQL
by Paul Lambert 31 Jul '07

31 Jul '07

Hi all, I think I might be being a little dense but when I add a NAS to my SQL database, it doesn't appear to be enabled until I restart my radius server. Is there a way to automatically activate a new NAS device that I add to the SQL database? Kind regards, Paul.

Radius Client
by Sofia Silva 31 Jul '07

31 Jul '07

Hi! i'm trying to authenticate a Linux client but i'm having some problems. I'm running the server in debbuging mode, and when i send a request from the linux client, the server rejects it saying "invalid password". The password it shows is sth like"/245/eer/m43...." and so on, so i thougth the problem could be the secret word. however, i've checked it, both in the server's clients.conf file, and in the client's servers file, and it's ok. I've also tried with "radstatus" and the message i get is "Packet does not contain required Message-Authenticator attribute" I would appreciate a lot if sb could help me. regards, Sofia _________________________________________________________________ Visita MSN Latino Noticias: Todo lo que pasa en el mundo y en tu paín, ¡en tu idioma! http://latino.msn.com/noticias/
