EAP-TLS works but not PEAP/EAP-TLS
Hi, I've got a Windows 7 machine attempting to connect to FreeRADIUS 2.2.0. EAP-TLS with a client certificate works fine, but with PEAP/EAP-TLS it doesn't. Is there anything I'm missing? The problem appears to be that the client doesn't send over the client cert. I know Windows is very fussy with what it accepts as a cert for EAP-TLS, but I'm confused as to why it works for one and not the other.

Re: EAP-TLS works but not PEAP/EAP-TLS
Thanks Martin, I had already changed this in the config, but it lead me to the real issue which was that I'd added a eap inner-eap section to my eap.conf, but I also had a modules/inner-eap file from the default config. When I removed modules/inner-eap file it all works fine. Thanks again, John.

EAP-TLS and TLS record protocol
Hello all, I'm new to the list, relatively new to authentication, and I'm trying to figure out some details regarding the RFCs. I was hoping some of you might be able and willing to help me out here. As I understand it, using TLS you can authenticate the server and optionally the client, negotiate the encryption/signing algorithm(s) for the TLS record protocol, and exchange the key information before switching to the selected encryption/signing algorithm(s) for secure data transport. EAP-TLS however seems focused on authorization and exchanging the key information, leaving the actual data encryption to be determine by other means (e.g. IEEE 802.1X MKA i.c.w. MACsec). My questions: 1. Is this understanding correct? 2. Does this imply that the negotiated encryption/signing algorithm(s) are only used for the EAP-TLS Finished messages? Any and all insights would be most welcome. :) Kind regards, Pieter Hulshoff - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

My questions: 1. Is this understanding correct? Sort of. You've focussed on EAP-TLS, but that's misleading. *All* EAP methods are solely for authentication; the EAP protocols are not used to forward traffic, they merely authenticate and, if the link-layer requries it, derive encryption keys. By way of illustrating the implications - note that, on a non-MACSEC 802.1x wired connection, you can (but shouldn't!) use EAP-MD5 which does not derive key material, because there's no link-layer encryption. Similarly, on wireless 802.1x, you can use EAP-PWD or EAP-EKE, both of which derive key material and both of which have nothing to do with TLS. 2. Does this imply that the negotiated encryption/signing algorithm(s) are only used for the EAP-TLS Finished messages? For *all* EAP methods, the only output is success/failure and optionally key material, and the key material is just a securely-derived set of bits. The cryptographic primitives used by the EAP method have no bearing on the cryptographc primitives used by the link layer. Also - this not not a FreeRADIUS question really, and if you have more questions, they might be better off in another forum. - List info/subscribe/unsubscribe?

Not at all - we are running it in production. The warning at the bottom is to make you think about what you're doing first, rather than to blindly copy my examples and then open yourself up to security issues that you haven't thought through. The examples are stripped down to their utter bare minimum - which is unlikely to be what you want in production.

If you don't want/need that, you're fine with plain EAP-TLS (and with less round trips, it will auth faster, too).

Question on certificates before deep dive into EAP-TLS
G'day
As a (hopefully) answer-able question to those experienced with EAP-TLS
that I've
been twisting my brain:
Usually I've seen example for EAP-TLS setups that used a server-side
certificate
issued from the same CA as the one it should allow EAP-TLS clients who
present
their certificate to FR.
Am I guessing correctly that CA_file can contain a different list of CA(s)
than the server certificate that is shown to the client? (Taken from
Debian's FR 2.1.12)
eap.conf:
tls {
[...]
certificate_file = /etc/freeradius/ssl/cert.p
# Trusted Root CA list
CA_file = /etc/univention/ssl/ucsCA/CAcert.pem
[...]
The real-life example would be that people could use PEAP-MSCHAPv2 for
credential-based logins (server certificate being signed by a trusted
external CA)
while some devices could login using EAP-TLS but only when they present
a certificate from an internal CA (that usually isn't being trusted by
devices
outside of control of IT department).
Best regards
Mathieu

Correct, that for sure isn't what I'd want :-) certificate_file - the server-side certificate - would contain the certificate (and it's trust chain) by the trusted CA.

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 configmuch 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. - List info/subscribe/unsubscribe?

Re: Setting up EAP-TLS as the ONLY authentication mechanism?
Thomas Hruska wrote: Nowhere in there does it explain why proxying is on by default. It just says that it can be turned off. I want to know why it is on by default in the first place. From what I'm beginning to understand, based on your reply, FreeRADIUS opens a port that isn't necessary for basic functionality as part of its default installation. That sort of behavior should at least raise an eyebrow if not a few red flags. You're unhappy that your questions got push-back. So you're pushing back in return. However... you know little or nothing about RADIUS, and I've been doing this for 20 years. I won't explain why there are no red flags in the default configuration. I *will* explain that it's unproductive for newbies to second-guess experts. The default client secrets(s) should be different from the default proxy secret(s) to avoid confusion for first-time users. So as a first-time user, you know more about their needs than someone who's done this for 20 years? I missed that it is there for testing. And I see why: Don't quote the config files at me. I wrote them. This just comes across as condescending, and lecturing me about the text I wrote. Again, defaults exist for a reason. The reasons for the defaults are what I'm actually after here. The reasons are given in the documentation, web pages, man pages, config files, etc. The defaults enable the server to do the Right Thing in the widest possible set of circumstances. i.e. so that newbies like you can get the server running with minimal work. Your response is to insult the developers, by claiming that the defaults raise red flags. Stop it. It's ignorant and annoying. All I was asking here was if commenting out those protocols in 'eap.conf' was all I have to do to disable them? A simple confirmation would suffice. I answered that. You're looking for reassurance that editing the config files won't cause the server to explode in flaming metal. It won't. Edit them. I admit that there is a little of that, but I'm just trying to save myself from breaking things too badly by understanding why the defaults are the defaults before I go and blow away large portions of config. The defaults are documented. See the comments in the config files. The procedure for editing the defaults is documented. See man radiusd. It's really not rocket science. You're looking for emotional reassurance that the server won't explode. I'm not going to give it. Instead, you should follow the documentation, and follow the documented methods for editing the configuration. If something goes wrong, it's just text. Put the old config back, and start again. And after doing this for 20 years, your message is typical of a particular class of newbie. The existing documentation is too complicated. Yet you don't ask a specific question. Instead, you have a long complicated post complaining about many things, and asking many questions. When I point this out, you start putting me down. I've had hundreds of conversations like this, and it's always annoying. Your entire approach is wrong. Read man radiusd. That documents the correct approach.

I've found that the latter creates a MUCH better experience for everyone (i.e. the nuisances go away - hey, I've been where you are at as well). I've also found that *I* have to actually write the documentation because no one else will do it for me (e.g. Wikis don't really work for software). And it isn't a FAQ, it is real documentation naturally covering a wide range of common (and even uncommon) topics. I always include a documentation cycle in my software releases - and it takes about a week to two weeks to complete, but it is so worth it.

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

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.

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

secret = testing123

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.

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.

Why is authentication on by default, you might just want to do accounting? why
is accounting on by default, you might just want to do authentication? It's on
by default because it does no harm having it on by default, and makes it easier
for people with no knowledge of the server to use the server.
You just add a realm, and it works, instead of having to toggle different bits
of config to make it work.
I think the configs could probably do with trimming a bit, but it does not make
sense to disable these things by default, as there are no security
implications, just a slight increase in memory usage.

Again it's so things just work. For rlm_logintime, if you read the code:
https://github.com/FreeRADIUS/freeradius-server/blob/master/src/modules/rlm_logintime/rlm_logintime.c#L157
If there's no Login-Time attribute in the request it does nothing. If there is
a Login-Time attribute in the request it ensures the user can only login before
that time.
It means you can add Login-Time in a users file, and it'll just work, instead
if hunting through the server to figure out where to turn on the Login-Time
module.

Re: EAP-TLS and OS X clients
Quoting a.l.m.bu...@lboro.ac.uk: SSL certs can be in various formats. Ones that are 'usable' depends on the underlying code, but the useful types are usually PEM, DER (also known as CER) and P12these are all active certs.

That straightened some things out for me. Eventually, though, it turned out that the most important issue was with OS X 10.7 (Lion). With this particular version of Apple's OS, the facility for adding enterprise network configurations is not as flexible as it once was. Now, if something different is required, a special (free) tool must first be obtained -- the iPhone Configuration Utility -- with which to create an XML profile that can then be applied. Not exactly what I was expecting, but that's the way it is. For anyone who might be interested, here's the set of instructions that I used: If your school uses TTLS with PAP (LDAP backend) then yah, the auto connection with ethernet will not help you. That is because the default EAP type that is supported is TTLS MSCHAPv2 (which is a bit more secure that PAP --ya ya, I know it is not fool proof). Anyway, all is not lost. You have three choices on how to get an 802.1X profie that supports TTLS with PAP onto your Mac. 1. Download iPCU and create a .mobileconfig file 2. Buy Lion server and use Profile Manager 3. Create a .mobileconfig (xml file) from scratch Options 2 and 3 are kind of a pain in the rear, so let's stick with option 1. Please put on your learning hat now **Please note this example is for a wired OR wireless 802.1X connection that requires TTLS and PAP for Lion clients** 1. Download and install the iPCUhttp://support.apple.com/kb/DL851 2. Open the iPCU (the iPCU is install in Applications - Utilities) 3. In the right hand side click on Configuration Profiles. 4. Click on New. (upper left) 5. You will see a new profile with a bunch of payloads (general, passcode, restrictions, etc). Don't worry you do not need to fill most of these out. 6. Click on General and fill out a Profile Name, Identifier (they can be anything) the rest of the fields you can leave blank. I used spam and spam. 7. Now click on WiFi. Do be scared here. Lion can use WiFi profiles for Ethernet (it will just ignore the SSID field). Click configure. 7a. For SSID ..If your school has a wireless network that uses TTLS with PAP, fill in the SSID name (wireless network name) that your school uses. If your school does not use wireless, then just use an label (e.g. spam). 7b. Ignore the hidden network field (unless of course your school uses a hidden SSID and you want to use wireless for this connection). 7c. Security Type ..Again if this is for Ethernet, just use WPA/WPA2 Enterprise. If this profile is going to be used for WiFi, then you need to find out what type of security your school uses. Most likely it will be WPA/WPA2 Enterprise (I hope). 7d. Once you choose WPA/WPA2 Enterprise you will see more options appear. Choose TTLS. 7e. Ignore EAP-FAST settings. Leave all boxes unchecked for EAP-FAST. 7f. For Inner Authentication choose PAP. 8. You will see three tabs, one for protocol (that you already filled out), one for Authentication and one for Trust. You can ignore trust unless you have the certificate from the radius server already loaded on your client. Don't worry if you do not have the cert, the Mac will load it (with your permission) during the first authentication. Ignore the Authentication tab for now. 9. Now look at the top left of the tool and choose Export 9a. for Security, just choose none (don't worry about signing it) 9b. Hit Export. 10. You will get a Save As dialogue box. Give the profile a name (like spam or something) and choose where you would like to save the profile. 11. Now goto where you save your profile and double click it. System Prefs will launch and try to install the profile. 11a. Just hit continue and continue again. 11b. You will be prompted for settings which are the username and password. You can either just hit install (the eapol supplicant will ask you for your credentials during the authentication phase) or you can fill them out now. BE SURE TO INPUT THE CORRECT INFORMATION. If you insert a bad username or password into this field, it will get saved as a keychain entry (with bad info) and you will never be able to connect. The Mac will just silently fail authentication until you delete the keychain entry and do a fresh auth. Save yourself some trouble and leave the fields blank and just hit install. 11c. You will be prompted for your admin password to install the profile. 12. The profile should be installed now. 13. In system prefs, click show all then click network. 14. If you click on your Ethernet interface you should now
Re: EAP-TLS and OS X clients
Hi, Eventually, though, it turned out that the most important issue was with OS X 10.7 (Lion). With this particular version of Apple's OS, yes, I know. Apple suck for doing this. I manage campus network at Loughborough university and eduroam federation in the UK and so am well aware of OSX and their idea of making OSX have the same .mobileconfig method as iOS. you might want to look into 'eduroam CAT' tool - as your NREN federation/eduroam people about it. whoa re your instructions aimed at? I worry a great deal about them because you arent telling them to install/verify a CA or a RADIUS server for the connection (thus basically negating the whole point of PKI!) and the site might use EAP-FAST (some places actually do more than just EAP-TTLS). also, end users dont need to run this tool! you (the admin) so all the hard work of configuring the profile and then just provide the end user/customer the *SIGNED* mobileconfig file alan - List info/subscribe/unsubscribe?

EAP-TLS and OS X clients
Hi folks, My WPA2-Enterprise configuration with Freeradius 2.1.0, EAP-TLS and 4096-bit SHA-1 certificates works great with wpaspplicant on Linux, but can anyone help me understand how to get this to work for OS X (Lion) clients? My Linux client uses a copy of the ca.pem file to establish the link (after which PAP is used to authenticate), but although the same ca.pem file can be imported into the OS X client's keychain, this certificate never shows up as a selectable identity when configuring EAP-TLS wireless access, like in this case (bottom of the page): https://wiki.thayer.dartmouth.edu/display/computing/Configuring+an+OS+X+Mac+for+the+Dartmouth+Secure+Wireless+Network In this example, the users are given a personalized *.cer certificate to add to their keychain. Since I don't have any client.cer files, I tried this approach with a client.csr file instead, which seemed personalized enough, but still I run into the same roadblock. Can anyone say what I should be doing differently? E.g. are *.cer certificates mandatory (if so, how can I make them?), or can I not use my self-signed certificates?

E.g. are *.cer certificates mandatory (if so, how can I make them?), or can I not use my self-signed certificates? rightSSL cerst can be in various formats. ones that are 'usable' depends on the underlying codebut the useful types are usually PEM, DER (also known as CER) and P12these are all active certs CSR is a certificate signing request file and isnt a valid cert for client use. if you have one type you can easily convert it to any of the other formats using 'openssl' on the command line of a Linux or OSX system - the command format isnt trivial...but its fairly obvious, the man pages over it and there are MANY web pages out there telling you how to do it. under Linux, most of the network admin tools for WPA2/WPA enterprise are fairly limited and fussy about certificates, how and where they are installed...on OSX you need to ensure you have the CA installed - and TRUSTED! alan - List info/subscribe/unsubscribe?

RE: [EAP/TLS] Authenfication through a certificate

Auth-Type eap {
eap
if ( %{TLS-Client-Cert-Subject} =~ /\/\// ) {
if ( %{TLS-Client-Cert-Subject} =~ /\/xxx\//

ok
}
else {

It's like when condition is checked, it bypassed users file.
Maybe, i must move these lines under authorize ?
anyone to confirm it ?

rlm_eap: No EAP session matching the State variable.
That is - we send an Access-Challenge containing an EAP request id=0,
the client responds with an Access-Request containing EAP response
id=255. This is obviously wrong.
FreeRADIUS mixes certain data into the State value with a xor
including the EAP id - that's why you're getting that particular error
message, but the underlying problem is that the NAS is not always
handling EAP id value wrap correctly.
I'm curious as to why the EAP id values are so large - I don't think
most NASes do this, they start from id=1 on every conversation, but I
don't know if it's legal.
The ID wrapping seems to work in other cases; I'm not certain, but it
*may* be that it only fails if the sequence is:
C: access-request EAP-response id=255 EAP-Identity
S: access-challenge EAP-request id=0 PEAP-start
C: access-request EAP-response id=255 PEAP-data
i.e. if the initial EAP-identity is the one with id=255.
But anyway - I think your NAS is buggy. There's no way you can solve
this in FreeRADIUS - you obviously can't rewrite the EAP id, so I think
you'll need to open a bug report with the vendor.
There is one thing you *might* be able to do which *might* work, but
it's dependent on what the NAS does - if I'm right and it's only
Identity packets that don't wrap properly, you might be able to detect
EAP identity packets and modify the ID and *maybe* the Extreme switch
will reply in-sequence. Like so:
authorize {
if (%{EAP-Message[0]} =~ /^0x02ff()01(.+)/) {
# we have an EAP-identity packet id=255, see if we can force a wrap
update request {
EAP-Message := 0x0201%{1}01%{2}
}
}
}
However - I have no idea if this syntax will even work, and to be honest
I'm extremely dubious that, if it does, the Extreme would respond properly.
Cheers,
Phil

Betreff: AW: AW: EAP-TLS Failed in handler question
With first packet I meant first packet the radius server saw in some time
... the switch forces a reauthentification every 2h
A re-auth is a fresh EAP session. So even on a re-auth, the first packet
would not have a State attribute, absent software bugs.
ok
It *could* be that the client just got stuck and is responding (very)
late. But I'm quite surprised the NAS didn't timeout the EAP auth before
that.
We're running Extreme Networks Switches with following timers set:
configure netlogin dot1x timers quiet-period 30
configure netlogin dot1x timers reauth-period 7200
We run SummitX edge, and when I've tested dot1x netlogin in the past, I
haven't seen this issue. We've never widely deployed it, however, so
it's possible there's an XOS bug where a small percentage of re-auths
erroneously re-use the State. You'd need to get a packet capture to be
sure.
ok ... will try to get one .. is not easy ...
but reject means the switch sets the port to the guest vlan, and therefor
the PC loses the connections ... is there a way to request a new full
eap/tls handshake from the client?
You're not understanding, or I'm not making myself clear.
Suggestion: fire up wireshark, and take a careful look at a normal EAP
authentication. You'll see that the first packet is an EAP-Identity
without a State attribute, which the server responds to with an
Access-Challenge containing the default eap type start payload, and a
State attribute.
Are you *absolutely sure* that these packets are really the first RADIUS
packet in the auth/re-auth?
will check again and get back to you
If you're sure, your problem seems to be that the correct first packet
isn't being sent; the switch is just jumping straight in with the EAP
payload *and* a State attribute

Interestingly, I see the RADIUS RFC does actually allow clients to send a previous State if you send an Access-Accept with: Termination-Action = RADIUS-request You're not doing that, are you? no, I'm not No. As above, re-auths start new EAP sessions. You would only reject any EAP sessions that were in the *middle* of performing an auth, as the state would be lost across restarts. But this is a very narrow window. so I would be best to set iptables to drop requests for 1min than restart the radius und remove the iptables rules? or can I set freeradius in a mode where is does not accept new sessions? and after 2 minutes I restart it? So that the switch is forced onto the other switch. or what is the best practice to never have falls rejects? - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
Re: EAP-TLS constant disconnects
Phil, thank you for your reply! I've tried to debug as you suggest. I run wireshark on the remote side + tcpdump on the server side. The results are really interesting and not expected. As the client is disconnected, it sends an auth request to the server. Server gets the request and after a successful authentication it sends back Access-Accept. Client gets this message. However, immediately after a successful authantication, it starts with the authentication process again and it loops like that. In the test time Access-Accept was granted 7 times, but client was still without connection and retrying. For tests I used a linux client on the remote side. After running dhclient for a couple of times the connection is usualy restored, sometimes it even takes to take down the interface and bring it up again to restore the connection. As of my understanding this does not prove a weak wifi as a reason for failure, as it does not prove that it is not the cause for trouble. Additionaly, there seems te be something else, besides wireless, which I can't explain, so feel free to commend and sugest! Regards!

The problem we experience is constant disconnects of the clients. After an some time (it seems like the intervals are random) of usage the connection drops. I don't have a debug output, since the server is in production allready and because of the valid traffic it's hard to efficiently debug it that way. A similar problem was allready reported some years ago (without an answer - at least not in that thread): http://bit.ly/10o9xkG The issue described in that post is symptomatic of wireless problems - interference, low signal, etc. - not RADIUS problems. The EAP Identity retries he mentions are on the *wireless* side i.e. the AP asking the client to start a re-auth. You problem also sounds like wireless to me; FreeRADIUS either: * receives auth requests and sends an accept * receives auth requests and sends a reject * receives auth requests that the client never completes It doesn't somehow magically disconnect the client (well, unless you're using the CoA functionality and you *ask* it to). I would suggest starting the debugging at the wireless side. Wait for a report of a disconnect, then search your logs. You could also start a rolling tcpdump on the RADIUS server of all auth traffic, and then search it for an auth request - I bet you don't see one. - List info/subscribe/unsubscribe?

AW: EAP-TLS Failed in handler question
Hi! first thx for your response. My first question is, how can I decode a EAP-Message from the debug Wireshark, or read the EAP RFC and decode it manually (see below) ok, I'll believe i got lucky and got a tcpdump trace on a client yesterday ... need to check it and if it is the same problem I'll provide more info. log to check if the request is itself ok. Here is first packet from No, this is *not* the first packet, because it has a State attribute, which is only present in 2nd and subsequent packets of the EAP exchange. With first packet I meant first packet the radius server saw in some time ... the switch forces a reauthentification every 2h The reason you're getting the error message is that the State attribute is unknown, so FR can't proceed with the EAP session and has no choice but to drop it. Check you haven't reduced the timer_expire value in eap.conf to a too-low value. # A list is maintained to correlate EAP-Response # packets with EAP-Request packets. After a # configurable length of time, entries in the list # expire, and are deleted. # timer_expire = 120 default was 60 .. I doubled it some weeks ago, as I saw No EAP session matching the State variable entries in the log. How many FR servers do you have serving this NAS? Is it possible the NAS is sending packets in a round-robin fashion (which is bad) which is why you're seeing a packet for which you don't have State? In this case it is only one .. we're running in pre-production with the IT department clients (about 100 clients) to make sure it is stable before rollout. But in production it will be more than one ... good point, we need to check that too, before going into production. I guess it's possible something is mangling the State attribute from the previous packet (which is *actually* the first packet). Otherwise, the client or NAS is doing something odd. It *could* be that the client just got stuck and is responding (very) late. But I'm quite surprised the NAS didn't timeout the EAP auth before that. We're running Extreme Networks Switches with following timers set: configure netlogin dot1x timers quiet-period 30 configure netlogin dot1x timers reauth-period 7200 following other timers are set to the default values: server-timeout Configure RADIUS server timeout for 802.1X supp-resp-timeout Configure supplicant response timeout rad_recv: Access-Request packet from host 10.xxx.xxx.4 port 44519, id=151, length=244 User-Name = host/x.tirol.local EAP-Message = 0x02ff00690d80005f160301005a01 Ok so this says: 02 - eap response ff - eap ID 255 - bit odd.. 0069 - length in hex 0d - eap type 13 (EAP-TLS) 80 - eap TLS flags = length included 005f - tls length 160301 - TLS packet 0x16==22==handshake record, version 3,1 (TLS 1.0) 005a - record length 01 - handshake=client hello cool !! etc. etc. So, it's the start of an EAP-TLS exchange, but as above, it's *not* the first packet. If you start a tcpdump on the server, you'll see how this works: C: Access-Request, no state, EAP-Identity=abc S: Access-Challenge, state=, EAP-TLS blah C: Access-Request, state=, EAP-TLS blah ok i.e. the NAS has to reflect the State back to FreeRADIUS on each packet. Something is interfering with that, or erasing the State at your end (a timer or restart). rlm_eap: No EAP session matching the State variable See? But I didn't see a reason for it ;-) Invalid means I return a reject ... should I return something else? No. but reject means the switch sets the port to the guest vlan, and therefor the PC loses the connections ... is there a way to request a new full eap/tls handshake from the client? Is this a client problem or a misconfiguration on my part? It's probably a client or NAS problem, unless you've set timer_expire too low. However: I guess this could also happen right after the server is restarted. Could that be it - is a cron job restarting it maybe? no the server is running for 10 days but if I would restart the server I would reject all clients to the guest vlan on reauthentication after that ... that can't be the designed way.

EAP-TLS Failed in handler question
Hi!
I've 802.1x (EAP-TLS) on a wired network activated, and it works 99% of the
time ... just some authentications fail, but some minutes later the same client
authenticates without a problem. As it happens only once every few days and
always with a new client I cannot put a sniffer between the PC and switch, as I
don't know which client is the next. But I enabled the debug logging on the
freeradius server. The Clients are Windows 7 PCs and I'm running
freeradius2-2.1.12-3.el5 on RHEL5.
My first question is, how can I decode a EAP-Message from the debug log to
check if the request is itself ok. Here is first packet from this client in
some time, and it already generates the error. But the same client worked
before and after it for days without a problem:

On 11/19/2012 08:23 AM, PENZ Robert wrote: My first question is, how can I decode a EAP-Message from the debug Wireshark, or read the EAP RFC and decode it manually (see below) log to check if the request is itself ok. Here is first packet from No, this is *not* the first packet, because it has a State attribute, which is only present in 2nd and subsequent packets of the EAP exchange. The reason you're getting the error message is that the State attribute is unknown, so FR can't proceed with the EAP session and has no choice but to drop it. Check you haven't reduced the timer_expire value in eap.conf to a too-low value. How many FR servers do you have serving this NAS? Is it possible the NAS is sending packets in a round-robin fashion (which is bad) which is why you're seeing a packet for which you don't have State? I guess it's possible something is mangling the State attribute from the previous packet (which is *actually* the first packet). Otherwise, the client or NAS is doing something odd. this client in some time, and it already generates the error. But the same client worked before and after it for days without a problem: It *could* be that the client just got stuck and is responding (very) late. But I'm quite surprised the NAS didn't timeout the EAP auth before that. rad_recv: Access-Request packet from host 10.xxx.xxx.4 port 44519, id=151, length=244 User-Name = host/x.tirol.local EAP-Message = 0x02ff00690d80005f160301005a01 Ok so this says: 02 - eap response ff - eap ID 255 - bit odd.. 0069 - length in hex 0d - eap type 13 (EAP-TLS) 80 - eap TLS flags = length included 005f - tls length 160301 - TLS packet 0x16==22==handshake record, version 3,1 (TLS 1.0) 005a - record length 01 - handshake=client hello etc. etc. So, it's the start of an EAP-TLS exchange, but as above, it's *not* the first packet. If you start a tcpdump on the server, you'll see how this works: C: Access-Request, no state, EAP-Identity=abc S: Access-Challenge, state=, EAP-TLS blah C: Access-Request, state=, EAP-TLS blah i.e. the NAS has to reflect the State back to FreeRADIUS on each packet. Something is interfering with that, or erasing the State at your end (a timer or restart). rlm_eap: No EAP session matching the State variable See? Invalid means I return a reject ... should I return something else? No. Is this a client problem or a misconfiguration on my part? It's probably a client or NAS problem, unless you've set timer_expire too low. However: I guess this could also happen right after the server is restarted. Could that be it - is a cron job restarting it maybe? - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
Wireless EAP-TLS Login from Notebook with User and PASSWORD
Hey there, I’ve setup a freeradius Server and am using EAP-TLS, and would need some help from you. The users file contains the username and the password beeing allowed to connect after TLS Connection has been established, and this is working on an android phone with no problems so far. One can setup the -CA Cert -User Cert -Login Name and -Password But I dont’t have an option to enter a password when I try to connect from the notebook, running Windows7. Is there an add on tool one can use to deliver the password as well, or do I have to drop the user-pass auth from ttls completely? FR is V2 EAP is set to allow TLS only Users file contains cleartext passwort auth (used from ttls, which has been used before) Thanks in advance and best regards Martin - List info/subscribe/unsubscribe?

We're not mangeling anything in FR. That's what I see, running FR in Debug-Mode. Maybe because we're running on a NT4-Sambadomain and are not using a AD? Since XP SP3 we establish a machine-auth via exporting, textediting and importing the profile-xml of the specific LAN-interface, we're authenticating using EAP-TLS, CN of the cert is the hostname. Machine-auth via WLAN is done by a registry-change. Ok, I'll keep looking. bye Alex - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
Re: EAP-TLS Machine-Auth Windows: difference between LAN and WiFi
The behavior _is_ configurable, but as you have observed for your particular network, the default is not to attempt machine auth. It is configurable on a per-network connection basis, I'm getting fuzzy on if it's adapter or SSID based. If the OP is observing such behavior, he needs to figure out why (what turned it on, is it consistent or the same for all users) and work with that. Dave.

I am aware that machine and user auth are configurable (FYI, it's per-adapter on LAN, per SSID on wireless). The issue the OP seems to be facing is that, when *doing* machine auth, he gets different format names on wired versus wireless. Windows doesn't do that, so either his RADIUS config or Wi-Fi network is mangling them. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

EAP-TLS Machine-Auth Windows: difference between LAN and WiFi
Hi, we're using FR 2.0 for our machine authentication for XP to Win7 with EAP-TLS. Everything is working so far, but I noticed a difference between authenticating via WLAN and LAN, which starts to be a problem for us now. If I make a auth via LAN the provided username ist hostname, if I do it via WLAN it is host/hostname. While we use host/ as a realm for our Radsecproxy, I'd like to change the behauviour for the authentication via LAN and add a string to the hostname (i.e. host/ or something else) to unify the login for WLAN an LAN. So how or where can I change that? A hint will be really welcome. TIA Alex - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

If I make a auth via LAN the provided username ist hostname, if I do it via WLAN it is host/hostname. While we use host/ as a realm for our Radsecproxy, I'd like to change the behauviour for the authentication via LAN and add a string to the hostname Don't. You will break EAP. (i.e. host/ or something else) to unify the login for WLAN an LAN. So how or where can I change that? A hint will be really welcome. Find a better solution. Change your rules so that you're keying off of the correct data, and doing that only when you want. Alan DeKok. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
Re: EAP-TLS Machine-Auth Windows: difference between LAN and WiFi
Hi Alan, thanks for your reply! Alan DeKok schrieb: host/ as a realm for our Radsecproxy, I'd like to change the behauviour for the authentication via LAN and add a string to the hostname Don't. You will break EAP. That's not clear. Why would that break EAP if the workstations are sending a different Login? It already does, depending on LAN or WLAN Logins. I don't mean some kind of rewrite or redirect inside of Freeradius. Using Linux I can send whatever I want as the loginname. Find a better solution. Change your rules so that you're keying off of the correct data, and doing that only when you want. I have now a more or less complicated regex rule in the radsecproxy, but I thought it's more elegant to unify both logins. I thought doing it in the profile-xml-file of the LAN connection in Win, but unfortunately it's not the right place for it. At least all official ressources I can find from MS, are not pointing out how to do that. bye Alex - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
