preprocess module

Hi all. Trying to understand and learn freeradius. For my use, I do not need the "huntgroups" or "hints" files, so I tried taking them out. I renamed the files from "huntgroups" to "huntgroups.off", and the same for hints. I then edited "module/preprocess" to take out references to these two files. However, when I start up radiusd, it appears that it's STILL looking for the files. I've gone so far as doing a "grep -ir huntgroup *", and every line it comes back with is commented out. Here's the debug and my modules/preprocess file: --debug start-- server { # from file /usr/local/etc/raddb/radiusd.conf modules { Module: Checking authenticate {...} for more modules to load Module: Checking authorize {...} for more modules to load Module: Linked to module rlm_preprocess Module: Instantiating module "preprocess" from file /usr/local/etc/raddb/modules/preprocess preprocess { huntgroups = "/usr/local/etc/raddb/huntgroups" hints = "/usr/local/etc/raddb/hints" with_ascend_hack = no ascend_channels_per_line = 23 with_ntdomain_hack = no with_specialix_jetstream_hack = no with_cisco_vsa_hack = no with_alvarion_vsa_hack = no } rlm_preprocess: Error reading /usr/local/etc/raddb/huntgroups /usr/local/etc/raddb/modules/preprocess[13]: Instantiation failed for module "preprocess" /usr/local/etc/raddb/sites-enabled/default[9]: Failed to load module "preprocess". /usr/local/etc/raddb/sites-enabled/default[1]: Errors parsing authorize section. --debug end-- --preprocess start-- preprocess { with_ascend_hack = no ascend_channels_per_line = 23 with_ntdomain_hack = no with_specialix_jetstream_hack = no with_cisco_vsa_hack = no } --preprocess end-- Anyone have any ideas on where it's getting this configuration from??? Thanks! --Brian

Hello, I need a little help:) I am setting radius for voip. I comment sql in default file (authorize, Authentication) and I enable voip-postpaid for postgresql.

nas-identifier regex based huntgroups
by Zdeněk Švarc 10 Jan '11

10 Jan '11

Hi guys, there are some posts about subj. refering to search mailing list archive. I did that, but not sure what is the best solution for 2.1.10 to solve this case. And of course, I would like to use regex for nas-identifier value. Thanks for your opinions. Regards, Z.

Does anyone has script to verify users session status with NAS, Actualy we are facing some missing Accounting information, and we can use radutmp module because we have multi radius servers and data is centralized in DB. Thank;

RADIUS, EAP and FreeRADIUS presentation in French
by Aurélien Geron 09 Jan '11

09 Jan '11

Hi, I wrote a presentation of RADIUS, EAP and FreeRADIUS, in French, for my colleagues. The presentation is quite detailed, and I thought it might be a good introduction for anyone interested in RADIUS, EAP and FreeRADIUS. I used Keynotes on Mac and I exported the result to HTML (unfortunately, it actually produces a bunch of roughly 170kB JPEG images, I don't know if there is a better export solution to HTML). Here's the result: http://aureliengeron.free.fr/livrewifi/freeradius.html I have two questions: is anyone interested in helping me translate it to English? I could try to translate about 10 slides per week in my spare time, but given that there are 215 slides... it will take months ! is there any better place you would recommend my publishing it? I would be happy to make it open source, should anyone else want to fix errors or contribute more information (I covered writing simple python modules, but not C modules, for example). Note: some of the diagrams are extracted from a WiFi book I wrote a few years back, and my publisher authorized me to publish some extracts on my website, but I will probably need his authorization before I can make those diagrams open source (I don't think he'll mind at all, though). Thanks for your feedback, Aurélien Geron

Two host with single user account in 802.1x with FreeRadius
by Xuan Sun 08 Jan '11

08 Jan '11

Hi All I find some issues with FreeRadius and look for some suggestions. I have two hosts, connect to a dumb switch. This dumb switch is connect to a Cisco switch (production network). 802.1x is configured in the Cisco switch. "multi-auth" is configured in the switch interface, so it supports multiple MAC addresses in the single port. As long as I use different user account in the two hosts, the 802.1x authentication works fine. If I uses the same user account/password in tow hosts, the 802.1x authentication is not working. Is it a Freeradius issue or switch issue ? Is there any way to fix it ? Thanks in advance. Regards

first authentification fail second one works
by Markus Burghart 07 Jan '11

07 Jan '11

Hello Guys I'm writing from Germany. I write my Bachelor Thesis about the Freeradius Projekt. I have a problem and i can't find a solution for it, at the internet by myself. I'm using version 2.1.9 of freeradius and everything works fine with the authentifications agains my Freeradius server, if I'm logged in at the system (Mac OSX, Linux and Windows) But I want to perform my authentifications while the system is currently booting because i use a LDAP Directory Server and i can't login against the LDAP Server if i haven't got a running Network-Connection (i will get the Connection if the 802.1X Authentification is successful. So i use wpa supplicant on Linux and w2secure on Windows to perform the Authentification while my system boots. But the debug mode tells me, at the first authentification test, that i'm running in a access-challenge (no reasons were given). Now, if i wait one minute and do nothing while waiting this time, i get a access-accept packet. Can you tell me why this happens and what can i do, that the authentification works with the first run while the system is still booting and so i could login to my operating system. I'm looking forword to hear from you Yours Markus rslautern 3724

rlm_python and dynload problem
by Aurélien Geron 07 Jan '11

07 Jan '11

Hi, I came across a bug when rlm_python executes python code that tries to load a dynamic (shared) module. This bug seems to have been discussed 2 or 3 times on this list, but no really satisfying solution appears to have been found so far (as far as I know), so I thought I might raise the subject again and perhaps try to contribute in finding a solution. In short, I think the solution to this problem is explained here, but I don't know how to implement it in freeRADIUS : http://docs.python.org/release/2.5.2/ext/link-reqs.html Here is my setup : - running a perfectly standard Debian Lenny (2.6.26-2-amd64) - installed the latest freeradius package from the lenny-backports (2.1.8+dfsg-1~bpo50+1) - the python debian package is the one installed with Debian Lenny (2.5.2-3) Here is my config: ---------------------------------------------- ####### # /etc/freeradius/modules/python ####### python python_test { mod_instantiate = radiusd_test func_instantiate = instantiate } ####### # /etc/freeradius/radiusd.conf ####### ... instantiate { python_test } ... ####### # /usr/lib/python2.5/site-packages/radiusd_test.py ####### def instantiate(p): radiusd.radlog(radiusd.L_DBG, "THIS WORKS") import random # this crashes radiusd.radlog(radiusd.L_DBG, "THIS IS NEVER REACHED !") ---------------------------------------------- Here is the output of "freeradius -X" : ---------------------------------------------- FreeRADIUS Version 2.1.8, for host x86_64-pc-linux-gnu, built on Apr 26 2010 at 21:49:28 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. You may redistribute copies of FreeRADIUS under the terms of the GNU General Public License v2. Starting - reading configuration files ... including configuration file /etc/freeradius/radiusd.conf ... Module: Linked to module rlm_python Module: Instantiating python_test python_init done python python_test { mod_instantiate = "radiusd_test" func_instantiate = "instantiate" } THIS WORKS rlm_python:EXCEPT:<type 'exceptions.ImportError'>: /usr/lib/python2.5/lib-dynload/math.so: undefined symbol: PyExc_ValueError /etc/freeradius/modules/python[24]: Instantiation failed for module "python_test" ---------------------------------------------- The module is properly loaded, the "instantiate" function gets called, and the first log message is output. In fact, any 100% pure python code works fine. The bug happens when a python module gets loaded dynamically : importing any module located in /usr/lib/python2.5/lib-dynload/*.so will crash. >From what I understand, here's what happens: 1) rlm_python was built against libpython2.5.a, but for optimization purposes, the linker stripped out all the symbols that were not used by rlm_python itself (including, for example, PyExc_ValueError). This behavior is platform-dependent, which probably explains why everything works fine on centos, for example. 2) when the radiusd_test module runs, it tries to import the "random" module, which itself tries to import the "math" module, which is in lib-dynload, and gets loaded dynamically. 3) unfortunately, python fails to load that module because it uses the PyExc_ValueError symbol and it does not know where it is defined (it is located in /usr/lib/libpython2.5.so.1, but unfortunately, the "math" module does not know that. As I said, I believe that the solution to this problem is clearly explained here: http://docs.python.org/release/2.5.2/ext/link-reqs.html As it's just a few paragraphs, I'll quote it here, for your convenience: ---------------------------------------------- While the configure script shipped with the Python sources will correctly build Python to export the symbols needed by dynamically linked extensions, this is not automatically inherited by applications which embed the Python library statically, at least on Unix. This is an issue when the application is linked to the static runtime library (libpython.a) and needs to load dynamic extensions (implemented as.so files). The problem is that some entry points are defined by the Python runtime solely for extension modules to use. If the embedding application does not use any of these entry points, some linkers will not include those entries in the symbol table of the finished executable. Some additional options are needed to inform the linker not to remove these symbols. Determining the right options to use for any given platform can be quite difficult, but fortunately the Python configuration already has those values. To retrieve them from an installed Python interpreter, start an interactive interpreter and have a short session like this: >>> import distutils.sysconfig >>> distutils.sysconfig.get_config_var('LINKFORSHARED') '-Xlinker -export-dynamic' The contents of the string presented will be the options that should be used. If the string is empty, there's no need to add any additional options. The LINKFORSHARED definition corresponds to the variable of the same name in Python's top-level Makefile. ---------------------------------------------- I think the short-term solution to this bug is to modify "src/modules/rlm_python/configure.in" and make it use the LINKFORSHARED linker options when linking rlm_python against libpython2.5.a., This could be done by adding a line such as: PY_OTHER_LDFLAGS=`sed -n -e 's/^LINKFORSHARED=$.*$/\1/p' $PY_MAKEFILE` just under this one: PY_OTHER_LIBS=`sed -n -e 's/^LIBS=$.*$/\1/p' $PY_MAKEFILE` and then using $PY_OTHER_LDFLAGS somewhere... the thing is, I have no idea where, because I am new to all these dynamic modules and embedded interpreters . I tried this though: python_ldflags="$PY_LIB_LOC $PY_EXTRA_LIBS $PY_OTHER_LDFLAGS -lpython${PY_VERSION} -lm" and recompiled the debian package (dpkg-buildpackage), but the problem was not fixed. Can someone tell me where to add those options exactly ? I can try recompiling as many times as necessary. Apparently, at least one person complains about the fact that you have to link against the static python runtime library (libpython2.5.a) even when you plan to use dynamic modules, and he has opened a bug report here: http://bugs.python.org/issue4434 Basically, if I understand correctly, his idea is to have the python fellows declare the proper dependencies in every *.so file, so that the libpython2.5.so.1 file gets loaded automatically when the "math" module (or any other dynamic module) gets loaded. Maybe that's the ideal solution, I really don't know. But it seems to me that we should try to fix freeRADIUS so that it works around this bug before python dependencies are fixed (it make take a while or even never happen). So I thing the only short-medium-term solution is to use LINKFORSHARED linker options. Thanks for reading this huge message. I hope we can beat this bug. Aurelien Geron

Normally i expect that the router or whom ever will generate a wpa key and the wlan router and the notebook should comunicate now.? Do you have any hints for me or do you need more information about the setup? thx Chris -- View this message in context: http://freeradius.1045715.n5.nabble.com/authentication-work-but-i-got-no-ac… Sent from the FreeRadius - User mailing list archive at Nabble.com.
