802.1X Extra Miles
by 3＠D4rkn3ss DuMb 05 May '16

05 May '16

Dear List, I hope you are all doing fine. I know that the following question might be 'out of scope' of the user's list but still, I would like to ask some user's experience. I successfully implemented '802.1x or MAC-Auth' as described on the how-to: the 802.1x is PEAP based (server's certificate deployed on all client) with Computer authentication (instead of user authentication) + Mac verification (in a specific table in radius db), and for all non-capable 802.1x end-points (such as pointers) just a mac verification. However, I m still confused about the following issues: - since the above are just only deployed in my testing environment, and I m supposed to deploy the same for 1k users, how much memory (RAM,HD,Processor) should I allocate to radius server! The DB is also on the same server as Freeradius. - what kind of extra-layer could I add to the authentication layer (PC authentication PEAP + MSCHAP v2, against AD 2008, + MAC Verification) to make it even 'more secure'? Thank you, Regards, KEN

Problem with multiple LDAP servers
by Jonathan Gazeley 05 May '16

05 May '16

Don't worry folks - this isn't a repeat of the same question about multiple LDAP servers. I've read the docs and I know how it's *supposed* to work, but I think I've found a discrepancy in the messages printed by the server. I'm running FreeRADIUS 3.0.11. I started off with an instantiation of the ldap module configured with multiple server names comma-separated on the same line, like this: server = 'ldap1.bris.ac.uk,ldap2.bris.ac.uk,ldap3.bris.ac.uk' This appears to work but on startup the server prints this warning: Warning: Listing multiple LDAP servers in the 'server' configuration item is deprecated and will be removed in a future release. Use multiple 'server' configuration items instead So, I tried that suggestion and ran with a config like this: server = 'ldap1.bris.ac.uk' server = 'ldap2.bris.ac.uk' server = 'ldap3.bris.ac.uk' But this yields a warning: Warning: /etc/raddb/mods-enabled/uobldap[22]: Ignoring duplicate configuration item 'server' For now I'm sticking with the old syntax which seems to do the right thing, but the spurious warning should probably be addressed in the server. Thanks, Jonathan -- Jonathan Gazeley Senior Systems Administrator IT Services University of Bristol

TLS: assigning certificates to username
by dump＠gmx.info 04 May '16

04 May '16

Dear list. I'm running freeradius 2.2.5 on Debian jessie. The system is configured to work in TLS and TTLS mode parallel and almost everything is running as expected. One thing is: In TLS-mode the dial-in user has to choose certificates and a username. My problem is now that the username can be chosen freely, as the username sent by the dial-in client is written only into the postauth and acct tables. Due to this the user is able to bypass any user specific regulations. I'm sure it is already documented, how to assign certificates to a dedicated username. But I so far didn't find it. Maybe somebody may give me a hint, where to look? Many thanks in advance and best regards Jens

"Unknown action 'rlm_sql_mysql'" in v3 unoffical ubuntu build
by Dustin S 04 May '16

04 May '16

I tried installing freeradius 3 using the ppa at: https://launchpad.net/~freeradius/+archive/ubuntu/stable-3.0 Everything works fine (passed all the tests for using the various types of authentication) but when I try to get it to use mysql, I get the following from "freeradius -X": Unknown action 'rlm_sql_mysql' The only idea I have is from http://wiki.freeradius.org/modules/Rlm_sql_mysql which says you should install mysql first so the libmysqlclient* libraries are automatically detected during compile. Dustin p.s.: here is more of the output: # Instantiating module "logintime" from file /etc/freeradius/mods-enabled/logintime } # modules radiusd: #### Loading Virtual Servers #### server { # from file /etc/freeradius/radiusd.conf } # server server inner-tunnel { # from file /etc/freeradius/sites-enabled/inner-tunnel # Loading authenticate {...} # Loading authorize {...} /etc/freeradius/sites-enabled/sql[31]: Unknown action 'rlm_sql_mysql'. /etc/freeradius/sites-enabled/inner-tunnel[48]: Errors parsing authorize section.

Dear all, @Alan Buxey <https://plus.google.com/u/1/111643914785537954652?prsrc=4> Actually, I just implemented a simple SQL select count(*) to my MAC table in radius db. There is no OS fingerprint or something similar! would be really great if you could give a hint about how to implement that :) @ Matthew Newton I will for sure move to EAP-TLS ... But before I think I need to have some 'respectable' PKI framework integrated in my current AD. The thing, the AD engineers don't really want to deploy 1k certificates :( (GPO), so i will have to find a way to convince the management. Thank you all for your input! This is ONE of the GREATEST open source project I have encountered till now, and I really LOVE (I eat it, drink it, and sleep on it) FreeRadius. Will for sure drop some cents out there for the support :) Regards On 4 May 2016 at 19:41, <freeradius-users-request(a)lists.freeradius.org> wrote: > Send Freeradius-Users mailing list submissions to > freeradius-users(a)lists.freeradius.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.freeradius.org/mailman/listinfo/freeradius-users > or, via email, send a message with subject or body 'help' to > freeradius-users-request(a)lists.freeradius.org > > You can reach the person managing the list at > freeradius-users-owner(a)lists.freeradius.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Freeradius-Users digest..." > > > Today's Topics: > > 1.

Disabling ntlmv1 usage in FR 3.0.12
by Alex Sharaz 04 May '16

04 May '16

... try again Hi, I've built a couple of 3.0.12 (ish) FR servers that I use as our outward facing ORPS servers. York users authenticate against these 2 when visiting other eduroam sites. in smb.conf I've got .... ntlm auth = no lanman auth = no client ntlmv2 auth = yes winbind max domain connections = 1024 restrict anonymous = 2 and in /etc/freeradius/mods-enabled/mschap I've got # An alternative to using ntlm_auth is to connect to the # winbind daemon directly for authentication. This option # is likely to be faster and may be useful on busy systems, # but is less well tested. # # Using this option requires libwbclient from Samba 4.2.1 # or later to be installed. Make sure that ntlm_auth above is # commented out. # winbind_username = "%{Stripped-User-Name}" winbind_domain = "ITS.YORK.AC.UK" ... and auths work quite happily Our systems people are always grumbling about our FR servers being the only boxes that use NTLMv1. Will the above config keep them happy and stop these servers from using it? Rgds Alex

help - zone migration
by Amardeep Singh 04 May '16

04 May '16

Hi, I am trying to implement zone migration on Nomadix. I have made the desired configuration settings on the Nomadix. However when I switch between the SSIDs it does not redirect me to the AAA page. Although I get authenticated on Nomadix but the redirection is not working. I have added the authentication query on free radius as (/etc/raddb/sites-enabled/default):- if ("%{Called-Station-Id}" =~ /^00-50-E8-/) { update request { Tmp-String-0 = "%{sql: SELECT radius_group_name from raduserzone where \ site_id='%{NAS-Identifier}' and \ mac_address='%{Calling-Station-Id}' and \ vlan_id='%{NAS-Port}'}" } if (&Tmp-String-0 != "") { update request { Tmp-String-1 := "%{sql: update radusergroup set \ groupname='%{Tmp-String-0}' \ where username='%{Calling-Station-Id}'}"; } } else { reject } } raduserzone is a custom table :- mysql> select * from raduserzone ; +----+---------+-------------------+---------+-------------------+ | id | site_id | mac_address | vlan_id | radius_group_name | +----+---------+-------------------+---------+-------------------+ I am using custom radius table here to track the guest data while switching in the database. I have attached the radius debug logs. Any ideas/suggestions? Thanks, Amardeep

how many clients use TCP Radius
by Florin Andrei 04 May '16

04 May '16

What clients actually use Radius over TCP? I can't find anything out there that's widely deployed and can query a Radius server over TCP. E.g. the Cisco documentation for routers, etc. seems to indicate that they only do UDP. The reason why I'm asking - I'm looking into setting up authentication for a variety of clients, with Radius used as a transport protocol, and I'm wondering if it's worth the trouble to even think about enabling TCP, or promising I could offer TCP. Thanks, -- Florin Andrei http://florin.myip.org/
