change Access-Reject output of module with unlang
by Mehdi Ravanbakhsh 25 Mar '13

25 Mar '13

Dear ALL How change Access-Reject output of module with unlang in sites-enable to Access-Accept and do some update control ? I can not find what is the replay attribute of reject or accept to check in "If condition" and change them in "update replay". and Do we have any reference for such variables?

Hi All, I've develop application which use freeradius and use coova as captive portal.I use jradius to communicate with freeradius. Now, new user will be store in my custom table (not in radcheck as default freeradius). Now i try to disconnect user online (use:admin) with command bellow : *sudo echo "User-Name=admin" | radclient -x localhost:3779 disconnect testing123* but i get no response like bellow : Sending Disconnect-Request of id 251 to 127.0.0.1 port 3779 User-Name = "admin" Sending Disconnect-Request of id 251 to 127.0.0.1 port 3779 User-Name = "admin" Sending Disconnect-Request of id 251 to 127.0.0.1 port 3779 User-Name = "admin" radclient: no response from server for ID 251 socket 3 I try to check 3779 port with netstat, but system not listen that port. Any suggestion how to solve this problem ?

Re: Setting up EAP-TLS as the ONLY authentication mechanism?
by Alan Buxey 24 Mar '13

Blah blah. But you don't say what the issue is with the documentation...in fact your issue was with the default config and your requirements...which are actually both fully documented in the config. I don't see why you've dropped in from nowhere, thrown your ego around and then claim to be leaving. Expect help/advice in the future? Because if so, you've gone about it the wrong way really alan

Setting up EAP-TLS as the ONLY authentication mechanism?
by Thomas Hruska 24 Mar '13

24 Mar '13

I want to set up FreeRADIUS using EAP-TLS only. I'm running Ubuntu Server 12.04.2 LTS here with the packaged build of FreeRADIUS from the default Ubuntu/Debian apt-get package repository. I'm finding junk scattered all over the place for configuring this thing (typical), so my first objective is to get FreeRADIUS into a locked-down state so that 'freeradius -X' doesn't return things that bother me (i.e. pared back to minimal functionality first). Since I only want EAP-TLS, output lines like the following bother me (I've inlined my concerns): FreeRADIUS Version 2.1.10, for host x86_64-pc-linux-gnu, built on Sep 24 2012 at 17:58:57 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/modules/pam ... including configuration file /etc/freeradius/modules/chap ... ^^^^^^^ Does FreeRADIUS really need to load all of those config files to function? That is, does it hurt in any way to load all of the module config files? From what I can tell, they don't seem to be relevant until they are instantiated later on, but I would appreciate confirmation. radiusd: #### Loading Realms and Home Servers #### proxy server { retry_delay = 5 retry_count = 3 default_fallback = no dead_time = 120 wake_all_if_all_dead = no } ^^^^^ What does this do? I don't think I need a proxy server. My setup is just a consumer router plus a single Ubuntu box with FreeRADIUS on it. home_server localhost { ipaddr = 127.0.0.1 port = 1812 type = "auth" secret = "testing123" response_window = 20 max_outstanding = 65536 require_message_authenticator = yes zombie_period = 40 status_check = "status-server" ping_interval = 30 check_interval = 30 num_answers_to_alive = 3 num_pings_to_alive = 3 revive_interval = 120 status_check_timeout = 4 irt = 2 mrt = 16 mrc = 5 mrd = 30 } home_server_pool my_auth_failover { type = fail-over home_server = localhost } realm example.com { auth_pool = my_auth_failover } realm LOCAL { } ^^^^^ All of this seems to be in proxy.conf. It doesn't look like I need any of it but I'm not sure if it is safe to get rid of it/comment it out. Again, this will be the only RADIUS server in the network and my understanding is that proxies are for forwarding requests to other RADIUS servers. Given my setup, can I safely comment out the '$INCLUDE proxy.conf' line in 'radiusd.conf'? radiusd: #### Loading Clients #### client localhost { ipaddr = 127.0.0.1 require_message_authenticator = no secret = "testing123" nastype = "other" } ^^^^^ Not sure why I would need this either. Based on the 'secret' string's value, I'm wagering it has to do with the 'proxy.conf' settings, but I'm not 100% confident about that. radiusd: #### Instantiating modules #### instantiate { Module: Linked to module rlm_exec Module: Instantiating module "exec" from file /etc/freeradius/modules/exec exec { wait = no input_pairs = "request" shell_escape = yes } Module: Linked to module rlm_expr Module: Instantiating module "expr" from file /etc/freeradius/modules/expr Module: Linked to module rlm_expiration Module: Instantiating module "expiration" from file /etc/freeradius/modules/expiration expiration { reply-message = "Password Has Expired " } Module: Linked to module rlm_logintime Module: Instantiating module "logintime" from file /etc/freeradius/modules/logintime logintime { reply-message = "You are calling outside your allowed timespan " minimum-timeout = 60 } } ^^^^^^ Most of that seems irrelevant to EAP-TLS. A certificate isn't exactly a password - it can expire, but the message "Password Has Expired" seems like it will never appear (or, if it does, it'll be confusing to a user). I'm probably not going to use the 'logintime' features. 'exec' might be useful since I probably will use the external 'openssl' based 'verify' method in 'eap.conf' (unless someone can suggest a better approach). radiusd: #### Loading Virtual Servers #### ... ^^^^^^ Even when 'default' was the only thing in 'sites-enabled', it loaded a bunch of stuff other than EAP-TLS. I currently have nothing in 'sites-enabled' right now, but would like insight into what the configuration file should be to just do EAP-TLS. radiusd: #### Opening IP addresses and Ports #### listen { type = "auth" ipaddr = * port = 0 } listen { type = "acct" ipaddr = * port = 0 } Listening on authentication address * port 1812 Listening on accounting address * port 1813 Listening on proxy address * port 1814 Ready to process requests. ^^^^^^ Again, I don't think I need a proxy and I'm not sure what the 'accounting' port is for. My policy is that "fewer open ports is better". So do I really want/need all of this? A few additional questions of where I'm currently a bit stuck: What do I need to do to set up FreeRADIUS so that it only supports EAP-TLS? Some of the stuff in 'eap.conf' is confusing. I've commented out 'md5', 'leap', 'mschapv2', etc. with only the 'tls' section left uncommented and set 'default_eap_type = tls', but I'm not sure if that is all I need to do. Documentation on setting up an "EAP-TLS only" RADIUS server is limited. What is the best method of setting it up so that only the router can communicate with the RADIUS server on port 1812?

Re: Setting up EAP-TLS as the ONLY authentication mechanism?

All that stuff is on by default to ensure that people who want more than a really dumb and minimal server can get up and running without having to try to find what combination of stuff needs to be enabled. So, eg proxying is enabled ..whats the issue? Unless you have actually edited proxy.conf to do something it won't do anything , there's no entry in clients.conf other than localhost too, so even if you had the required ports open to the world, nothing is going to happen. If all you want is EAP-TLS auth then its very easy to minimise to that config....much much easier than having to learn the server better and trying to get there from a minimal config that doesn't work out if the box (ask those who have tried doing it that way...look at mailing list history for those that stripped the config out before then trying to get things to work) This isn't Apache, which does have a whole load of things on and can get you p0wned on port 80 if you have that open to the world alan -- This smartphone uses free WiFi around the world with eduroam, now that's what I call smart.

rlm_checkval and Hint attribute
by Tony Peña 22 Mar '13

Hi again... I'm starting taking some confuse idea with this... I use 3 checkvals. 1 for Calling-Station-Id 2 for Called-Station-Id and 3 for Hints and in the Hints file.. i setup my hints domains and filter to can apply for the suffix the correct acl/pool ip. also have radiusHints and radiusFilterId in my OpenLDAP db. now.. my question is.. why if Hints is not found in radius query... continue checking the rest for the values... and with any checkvals 1 or 2 works fine.. ?? so... if some user use other hints radius do access-accept... and not the reject like callings/called-station-id who with that... works fine.. simple debug.

regex in suffix
by Tony Peña 22 Mar '13

22 Mar '13

Hi to all. I have some suffix configure, to can do load balance between some sql accountings servers. and I have this check into radiusd.conf if (User-Name =~ /^(.+)(a)institute.domain.cu/) { monthlycounter2 } else { monthlycounter1 } and I have some users configured to can access by other way in the public PAP, using part of the suffix so i want to balance too in fact.. the question is my suffix for @institute @institude.domain @institude.domain.cu can use monthlycounter2 and the rest.. with only been 'just the user part' by montlycounter1 i test this if (User-Name =~ /^(.+)(a)institute?.domain?.cu/) { monthlycounter2 } else { monthlycounter1 } and the servers running fine.. but i'm not sure if the regex is defined ok... can help me in that...? thanxs in advance. -- Antonio Peña Secure email with PGP 0x8B021001 available at http://pgp.mit.edu Fingerprint: 74E6 2974 B090 366D CE71 7BB2 6476 FA09 8B02 1001

[Help] Is that possible to change the reject message that appears at the Windows Pop Up
by Danny Kurniawan 21 Mar '13

21 Mar '13

Hi All, So i have been able to authenticate my wireless user using 802.1x + LDAP + MAC address (using CallingStationID attriubute). So now for example when user A have MAC 11:22:33 but tried to login using another device there will be a pop up window when they try to connect - just a plain error popup saying "Unable to connect". Is there any way we can customize this error from radius? or should be from the wireless AP? So below is the unlang code that i use to check whether the user have a set of MAC address in their ldap profile or not if(!control:Calling-Station-Id){ reject } Possible to have that reject command to return some code that Windows client can understand like "No MAC address" etc? Thanks in advance Danny -- Best Regards, Danny
