Freeradius with EAP-SIM
by Ronaldo Afonso 16 Nov '11

16 Nov '11

Hi all, I'm trying to make a test environment to authenticate users via EAP-SIM. I followed some freeradius documentation (freeradius-server-2.1.12/src/tests/eapsim-03) but when I start the radeapclient it just get stuck waiting for some FreeRadius server "response" The scenario is a FreeRadius listening on localhost interface and a radeapclient sending "Access-Requests" to that server. radeapclient -c3 -r1 -s -x 127.0.0.1 auth localhost-secret <eapsim-in.txt +++> About to send encoded packet: User-Name = "1232010000000000" NAS-IP-Address = 127.0.0.1 EAP-Code = Response EAP-Type-Identity = "1232010000000000" Message-Authenticator = 0x30 NAS-Port = 10 EAP-Sim-Rand1 = 0x30000000000000000000000000000000 EAP-Sim-SRES1 = 0x30112233 EAP-Sim-KC1 = 0x445566778899aabb EAP-Sim-Rand2 = 0x31000000000000000000000000000000 EAP-Sim-SRES2 = 0x31112233 EAP-Sim-KC2 = 0x445566778899aabb EAP-Sim-Rand3 = 0x32000000000000000000000000000000 EAP-Sim-SRES3 = 0x32112233 EAP-Sim-KC3 = 0x445566778899aabb radclient: no response from server It seems me that radeapclient is waiting for some freeradius server packet. I thought radeapclient was supposed to initiate the EAP-SIM authentication process, not the server. I'm running FreeRadius version: FreeRADIUS Version 2.1.8, for host i486-pc-linux-gnu, built on Jan 5 2010 at 02:49:11 And the FreeRadius server users configuration file is: 1232010000000000 Auth-Type := EAP, EAP-Type := SIM, EAP-Sim-Rand1=0x30000000000000000000000000000000, EAP-Sim-SRES1 = 0x30112233, EAP-Sim-KC1 = 0x445566778899AABB, EAP-Sim-Rand2 = 0x31000000000000000000000000000000, EAP-Sim-SRES2 = 0x31112233, EAP-Sim-KC2 = 0x445566778899AABB, EAP-Sim-Rand3 = 0x32000000000000000000000000000000, EAP-Sim-SRES3 = 0x32112233, EAP-Sim-KC3 = 0x445566778899AABB All attributes are on the same line. I included the eap { } On the eap.conf file Any help would be appreciated!!! Thanks ... -- Ronaldo Afonso www.vexcorp.com +55 11 4932-5971 ronaldo.afonso(a)vexcorp.com

How to proxy only any type of requests
by IT Support 16 Nov '11

16 Nov '11

Hi folks, I a newbie freeradius user and I have a new problem. I have a switch that send auth request to a FreeRadius. I need that if the auth request if for a windows user (for example user NTCETEMMSA\guillem) resend the request to a windows nps server, but, if the auth request is a MAC address (for example 00-24-54-3E-04-5A/NOPASSWORD), the FR use the users file for auth this. The problem is that the FR always auth only with users file or always auth only with the windows nps server. This is my proxy.conf server: realm LOCAL { } realm NULL { type=LOCAL nostrip } realm DEFAULT { type = radius authhost = 192.168.120.4 accthost = 192.168.120.4 nostrip secret = J3q0fHat } And my users fils: "00-24-54-3E-04-5A" Auth-Type := "Local", User-Password = "NOPASSWORD" tunnel-type = 13, tunnel-medium-type = 6, tunnel-private-group-ID = 910, Filter-Id = "Enterasys:version1:policy=Admon" Anybody can help me please? Thanks a lot for your help. Toni

Keeping plain-text shared secret and user passwords in sql
by asdf zxcv 16 Nov '11

16 Nov '11

I'm attempting to use freeradius to authenticate wireless network in my organisation, using self-signed certificates. I have installed freeradius 2.1.10 from debian 6 repository, set up basic configuration according to instructions on freeradius.org site, finally I've configured freeradius to use mysql. It seems to work properly, but i wonder if it is safe to keep user password and client secret in plaintext? I searched the lists and googled a bit, but I can't find any information regarding this case. So: 1 - is there a way (or sense) to hash shared secret in my database? 2 - Can I hash user passwords if I'm using eap-tls? 2a - if I'm using certificates for authentication, do I actually need to keep user passwords? Cause it seems that they aren't used during authentication (or I didn't find that part during debuging) Regards Peter

/dev/null proxy accounting while proxy sink is unresponsive
by jared r r spiegel 15 Nov '11

15 Nov '11

hi. thanks for freeradius. we converted from Radiator to freeradius and were able to halve the size of our radius cluster while still handling more load. we're using multiple detail files defined in radiusd.conf, which then sites-enabled/default defines as redundant-load-balance, so accounting gets written to them round-robin by freeradius. then we have another sites-enabled/ "site" defining multiple servers each listen to one of the accounting files and Proxy-To-Realm them to a realm which is defined in proxy.conf. the realm in proxy.conf has home_servers and home_server_pools defined for multiple different realms, each sending to different proxy sinks. some sinks are just one host, some are multiple. this all works pretty much great, except when a proxy-sink fails to ACK the accounting we send it (thus being seen as dead or zombie). there are a small number of cases where we would love it if we could just /dev/null this proxy accounting if the remote server is dead/zombie, however i haven't figured out a way to actually configure this. it seems like i want to use a "fallback" server in the home_server_pool, where that fallback server would just 'ok' accounting or otherwise toss it in the trash, but after a few iterations of trying to make this work i have come up empty handed. if anyone can help, i'd be enormously grateful. here are the sanitized configs. so for example, i'd like to add a virtual server to the 'home_server_pool proxy-whatever' that would toss the accounting from the detail file into /dev/null for whatever period of fime site-1 and site-2 were dead/zombie.

LDAP/MSCHAP

All, I am really close to a successful Freeradius implementation for 802.1X wireless using LDAP authentication on the back end. Here is what I have: - RADTEST / clear text Freeradius password from "users" file / WORKS GREAT - Windows XP 802.1X PEAP/MS-CHAPv2 wireless client / clear text Freeradius password from "users" file / WORKS GREAT - RADTEST / LDAP credentials / WORKS GREAT - Windows XP 802.1X PEAP/MS-CHAPv2 wireless client / LDAP credentials / NO GO Here is the debug output. I have read others online with these symptoms but nothing I have found yet will help me. [mschapv2] +- entering group MS-CHAP {...} [mschap] No Cleartext-Password configured. Cannot create LM-Password. [mschap] No Cleartext-Password configured. Cannot create NT-Password. [mschap] Creating challenge hash with username: mwhitlow [mschap] Told to do MS-CHAPv2 for mwhitlow with NT-Password [mschap] FAILED: No NT/LM-Password. Cannot perform authentication. [mschap] FAILED: MS-CHAP2-Response is incorrect Thanks much in advance for the help! Mike

Issues with EAP-TLS and OpenSSL
by Houston-III, Lester L 15 Nov '11

I'm trying to configure my FreeRADIUS server to support EAP-TLS but it keeps reporting that there is no OpenSSL support. I'm currently using FreeRADIUS version 2.1.12 on Centos 6. I built the server from source because I needed to include the JRADIUS plugin. I have been able to get things working with the JRADIUS and PAP, but now I'm trying to use EAP-TLS. I have already installed OpenSSL core, static and development packages using yum. Issuing the configure commands always results in a statement that OpenSSL is not supported, (Checking for OpenSSL support .. no) What I'm I missing? Does another package needs to be installed?

PEAP/mschapv2 - opendirectory
by Kemal YILDIRIM 15 Nov '11

15 Nov '11

Hello all, I've just able to implemented Wired 802.1x system with PEAP/mschapv2 authentication against opendirectory which is running on MacOSX server 10.6.8 Leopard. At the end I have a "working" setup, but I like to learn more to fix my faults. below you can find my study steps and config changes And these are my question regarding to the following outputs. Q1- Is it possible to get radius attributes with opendirectory module ( not well documented)? if yes, please share your experience. Q2- I am not sure what is happining during below mschap challenge/response. [mschapv2] +- entering group MS-CHAP {...} [mschap] No Cleartext-Password configured. Cannot create LM-Password. [mschap] No Cleartext-Password configured. Cannot create NT-Password. [mschap] No NT-Password configured. Trying OpenDirectory Authentication. [mschap] OD username_string = onex, OD shortUserName=onex (length = 4) [mschap] dsDoDirNodeAuth returns stepbuff: S=D134BC291881FAF31275724FE84FEA40648F64C6 (len=40) ++[mschap] returns ok MSCHAP Success 　 1. Testbed: Auth Server : FreeRadius 2.1.3 running on MacOSX 10.6.8 Leopard, other services: opendirectory (openLDAP), Kerberos, DNS, DHCP Authenticator : HP Networking 2910 switchSupplicants : WindowsXPsp3, Windows7, MacOSX (PEAP/mschapv2)Directory Admin : diradmin Test User : onex authentication : opendirectory (mschap module is calling opendirectory module for challenge response) authorization : by ldap search in post-auth section inside of inner-tunnel server. authorization : settings are Tunnel-Type, Tunnel-Medium-Type, Tunnel-Private-Group-Id (by ldap search) sql client db : Mac OSX serveradmin GUI have an access to configure radius clients (max count is 64), I am not using clients.conf as I understood Mac OSX server actually using openLDAP, but Apple named it as "opendirectory" by restricting and changing of access medhods. There was no radius schema file in Apple's distribution of FreeRadius, or at least I could not find it where it normally would be. So, downloaded the schema file and extended it manually. 　 2. LDAP schema extention and creating radius attributes for 802.1x /etc/openldap/slapd.conf include /etc/openldap/schema/radius.schema slaptest -f slapd.conf -F slapd.d /etc/openldap/slapd.d/cn=config/cn=schema/cn={10}radius.ldif dn: cn={10}radius 　 restart host or restart slapd dscl cd LDAPv3 auth diradmin abc123 cd 127.0.0.1/Groups/vlan10 create . radiusTunnelPrivateGroupId 10 cd .. cd vlan20 create . radiusTunnelPrivateGroupId 20 ... I will set Tunnel-Type and Tunnel-Medium-Type statically in post-auth section, radiusTunnelPrivateGroupId attribute is sufficiant in LDAP. 　 3. Radius config Non-default or changed parameters are written here. LDAP module will not be used for authentication, will be used only to set radiusTunnelPrivateGroupId Authentication would be done through opendirectory module by mschap call. MacOSX issue : without Apple base stations Radius service could not be started from serveradmin GUI need to be fixed by deleting some lines regarding BaseStation check in the following file. /Applications/Server/Server\ Admin.app/Contents/Resources/RoleBasedSetup.bundle/Contents/PlugIns/RadiusPlugin.plugin/Contents/Resources/RadiusSteps.plist 　 /private/etc/raddb/modules/ldap ldap { server = "radsrv.lab.com" identity = "uid=diradmin,cn=users,dc=radsrv,dc=lab,dc=com" password = abc123 basedn = "dc=radsrv,dc=lab,dc=com" filter = "(uid=%{%{Stripped-User-Name}:-%{User-Name}})" // In my test only User-Name is used base_filter = "(objectclass=radiusprofile)" set_auth_type = no // As I know LDAP only working with pap authentication } 　 /private/etc/raddb/attrs DEFAULT Tunnel-Type == VLAN, Tunnel-Medium-Type == IEEE-802, Tunnel-Private-Group-Id =* ANY, 　 /Private/etc/raddb/ldap.attrmap checkItem User-Name uid // I am not able to check ntlm or other hashes, only uid check for "return noop" replyItem Tunnel-Type radiusTunnelType replyItem Tunnel-Medium-Type radiusTunnelMediumType replyItem Tunnel-Private-Group-Id radiusTunnelPrivateGroupId 　 /private/etc/raddb/radiusd.conf max_request = 16384 proxy_requests = no #$INCLUDE clients.conf // MAX Client count is 64 in sql db ( if I run out of space, will use clients.conf in addition) 　 /private/etc/raddb/proxy.conf realm LAB.COM { // doing nothing, but like to use it } /private/etc/raddb/eap.conf default_eap_type = peap #gtc #leap #md5 tls { private_key_password = Apple:UseCertAdmin private_key_file = "/etc/certificates/radsrv.lab.com.23C900DA0044BDB9E24ACE1BCFAFFB0747756C25.key.pem" certificate_file = "/etc/certificates/radsrv.lab.com.23C900DA0044BDB9E24ACE1BCFAFFB0747756C25.cert.pem" CA_file = "/etc/certificates/radsrv.lab.com.23C900DA0044BDB9E24ACE1BCFAFFB0747756C25.chain.pem" dh_file = /etc/raddb/certs/dh random_file = /etc/raddb/certs/random } peap { use_tunneled_reply = yes } /private/etc/raddb/sites-enabled/default authorize { #chap #unix #files #pap } authenticate { # Auth-Type PAP { # pap # } # Auth-Type CHAP { # chap # } # Auth-Type opendirectory { # opendirectory # } #unix # Auth-Type LDAP { # ldap # } ... } 　 /private/etc/raddb/sites-enabled/inner-tunnel authorize { #chap #mschap #unix #files #LDAP is checking uid only, enabled for post-auth section ldap #pap } authenticate { # Auth-Type PAP { # pap # } # Auth-Type CHAP { # chap # } } #unix #suffix # in ldap search radiusTunnelPrivateGroupId attribute is reached if cn=vl* AND memberUid=%{User-Name} # all group names need to start with "vl" # attribute value "10" returns in this case post-auth { update reply { Tunnel-Type = VLAN Tunnel-Medium-Type = IEEE-802 Tunnel-Private-Group-Id = "%{ldap:ldap:///dc=radsrv,dc=lab,dc=com?radiusTunnelPrivateGroupId?sub?(&(cn=vl*)(memberUid=%{User-Name}))}" } } 　 4.
