How long it take to auth in 802.1X/WPA-enterprise? I set up 802.1X/WPA-Enterprise network simply as follows. Free radius 2.1.8 server ubunt on VMware 10.10.20.14 | |EAP-TLS(wired. 802.3) | AP Belkin 54g WPA-Enterprise Tkip : :EAP-TLS(wireless 802.11) : Client : Laptop Windows 7 (Self certification) kkk(a)xxxx.yyy.zz.vv In this simple network model, I have tried to auth using EAP-TLS(self-certification) and it works good. By the way, about 18 seconds are taken to auth as follow debug logs. (confer the timestamp (1) and (2)) ....... .......

Is it right? I can't understand the taken time 18 seconds. it's too long. Can you explain what is wrong? I don't think it due to system performance or network throughput. Maybe configuration file problems... Thanks in advance.^^ Best, Jaejong Baek

I'm trying to get FreeRadius working with a Cisco WLC. I would like to match on Airespace-Wlan-Id to permit access to certain SSIDs. I can't seem to deny access using this attribute. Is there a trick to this? Thanks, -adam

How to configure EAP PEAPv0/EAP-MSCHAPv2 in freeradius 2.10 Ubuntu linux 9.04
by Dilip Patel 17 Feb '10

17 Feb '10

I am using FreeRADIUS Version 2.1.0 in Ubuntu linux 9.04. How do I configure Free Radius to use EAP PEAPv0/EAP-MSCHAPv2? I have updated the default configuration in eap.conf to the following: eap { # Invoke the default supported EAP type when # EAP-Identity response is received. # # The incoming EAP messages DO NOT specify which EAP # type they will be using, so it MUST be set here. # # For now, only one default EAP type may be used at a time. # # If the EAP-Type attribute is set by another module, # then that EAP type takes precedence over the # default type configured here. # default_eap_type = peap However, I get the following error output in initializing modules: root@pateldil-desktop:/etc/freeradius# freeradius -X FreeRADIUS Version 2.1.0, for host x86_64-pc-linux-gnu, built on Apr 30 2009 at 07:39:22 Copyright (C) 1999-2008 The FreeRADIUS server project and contributors.

How to access config parameters for rlm_perl
by David Donn 17 Feb '10

17 Feb '10

Hi, I want to set up some config parameters for use in my perl module. I think these are supposed to be in the RAD_CONFIG hash. But this hash always seems to be empty. Any ideas? Maybe I have I have my config parameters defined in the wrong place? Cheers, David Donn My site file: accounting { example } My rlm_perl config file (from /etc/raddb/modules): perl example { module = ${confdir}/example.pl foo = bar } My perl code (example.pl): use strict; # use ... # This is very important ! Without this script will not get the filled hashesh from main. use vars qw(%RAD_REQUEST %RAD_REPLY %RAD_CHECK %RAD_CONFIG); use constant RLM_MODULE_OK=> 2;# /* the module is OK, continue */ use constant LOG_ERROR => 4; sub accounting { # doesn't print anything, expected it to print "module = /etc/raddb/example.pl" and "foo = bar" foreach my $k (keys %RAD_CONFIG) { &radiusd::radlog(LOG_ERROR, "Config $k = $RAD_CONFIG{$k}"); } return RLM_MODULE_OK; }

which module causes this?
by Kledi Andoni 17 Feb '10

17 Feb '10

Hello, Very often, I can say at least 50% of the time I get: Auth: Login incorrect: [1d15057j6p4/\270\310\344\024\n\265E!-\233M\2766\276:] (from client private-network-2 port 1 cli) The username: 1d15057j6p4 is correct, but as you can see the password is not transmitted correctly, although im very sure I typed it right. Any suggestions? Thank you, k

update session database in Authorization
by Houssam Melhem 17 Feb '10

17 Feb '10

Hello, When 2 users with same username try to login to the server at the same time; Radius server receives Auth and Acct packets in the following order: 1- Auth from user1 2- Auth from user2 3- Acct from user1 4- Acct from user2 Since the session database is not populated until a user sends an accounting packet (using radutmp or sql modules) How can we prevent multiple login in this situation? shall we think in adding a record to the session database in authorization section? I am using freeradius-2.1.6 configurations ============= authorize { preprocess chap suffix files sql pap } preacct { preprocess acct_unique suffix files } accounting { # radutmp sql } session { # radutmp sql } Thanks, Houssam

Hello, Im very new to freeradius so apologies if this is a dumb question. I installed freeradius2.1.8 on a Fedora 12 system today, when the install had finished I started radius with "radiusd -X" Another window was opened to run radtest: radtest test test localhost 0 testing123 Sending Access-Request of id 253 to ::1 port 1812 User-Name = "test" User-Password = "test" NAS-IP-Address = 127.0.0.1 NAS-Port = 0 Sending Access-Request of id 253 to ::1 port 1812 User-Name = "test" User-Password = "test" NAS-IP-Address = 127.0.0.1 NAS-Port = 0 Sending Access-Request of id 253 to ::1 port 1812 User-Name = "test" User-Password = "test" NAS-IP-Address = 127.0.0.1 NAS-Port = 0 radclient: no response from server for ID 253 socket 3 I expected to see a Access-Accept or Access-Reject.

radius for linux authentication
by sri.b＠aol.in 16 Feb '10

16 Feb '10

Hi List, I have configured my linux devices to use freeRadius (freeRadius 1.1.5 with MySQL backend) authentication. Installation of pam library went well and am able to get authenticated against my freeRadius server. Now the problem is how to identify a user like root have same name on multiple machines. For this I observed that this PAM library is sending Calling-Station-Id in Access-Request packets. I did modify my radcheck table to have entires as following: +----+-----------+--------------------+----+----------------+ | id | UserName | Attribute | op | Value | +----+-----------+--------------------+----+----------------+ | 1 | linuxuser | Password | == | radpwd | | 12 | root | Calling-Station-Id | == | 192.168.100.61 | | 11 | root | Password | == | 10radpwd | | 10 | root | Password | == | 61radpwd | | 13 | root | Calling-Station-Id | == | 192.168.70.10 | +------------------------------------------------------------------------------ But the failed to authenticate. Please suggest what could be the problem, ASAP. Also, are there any other ways to handle this kind of situation. Appreciate your help. Regards, Sri.
