Re: Dynamic VLAN assignment depending on LDAP user group and MAC address
Fabrizio Vecchi wrote: First of all, sorry if my email is very long, I am just trying not to leave any important details out. :) That's good. So far, I managed to do the dynamic VLAN assignment, but cannot seem to get it to work together with the MAC checking. They key thing to remember is that they are two independent pieces. Get them working independently. Then, put the pieces together. I can get an auth to be refused if the MAC is not listed in the authorized_macs file, but can't quite put the two things together. Perhaps I am a bit confused with regards to where to put the MAC check. Put it into authorize. For now, I just managed to get the check to work only on the authorization phase in sites-enabled/default, but then the VLAN assignment, which is done in the internal-tunnel, seems to overwrite my changes. That can be fixed. So I tried to put the MAC check in the post-auth section in the default file, but the MAC check doesn't seem to ever work. Because the users file works differently there. Here are the relevant config files: Which seem to use a reasonable approach. As you can see, the device wasn't listed in the file, the authentication went fine, saying that the tunnel that I should get has ID 40, but that wasn't overwritten by the authorized_macs check... I think part of the problem is you're juggling a lot. You also mentioned MACs and VLANs... and then halfway through the message Oh, there's an inner-tunnel, too. Stop with all of your solutions. Instead, write down exactly what you have. Write down what you want to happen in plain English. Write down what should happen, and when. Then, convert it to the configuration. Your system is using TTLS. OK... I'll ignore the question of *why* you're authenticating unknown MACs. That seems weird. The debug log shows this: [ttls] Got tunneled reply code 2 Tunnel-Type:0 = VLAN Tunnel-Medium-Type:0 = IEEE-802 Tunnel-Private-Group-Id:0 = 40 Where did that VLAN come from? Why is it there? If you don't know, that's a huge problem. Generally, the policies should be arranged like this: authorize: allow only known kinds of authentication decide which authentication method to use grab known good passwords authenticate: run authentication methods post-auth: return attributes for a successfully authenticated user In your case, I'd say return to a default configuration. Then, get the MAC address filtering working in post-auth. Once that's working, add VLAN assignment. Alan DeKok. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
Re: Dynamic VLAN assignment depending on LDAP user group and MAC address
Fabrizio Vecchi wrote: I guess at the end of the day my question boils down to the following: where should I put the MAC check, so that the user gets assigned to the right VLAN? In post-auth. If I put it in the authorize part of sites-enabled/default, the VLAN update request will get overwritten by the post-auth part of sites-enabled/inner-tunnel; The default configuration for the inner-tunnel does *not* set a VLAN in post-auth. So one configuration you added prevents you from using another configuration you added. and if I put it in the post-auth of the file sites-enabled/default file (which gets executed after inner-tunnel), the authorized_macs function always returns noop. Delete the set VLAN stuff from the post-auth of the inner tunnel. As you've seen, it breaks the other configuration you're trying to use. When you put authorized_macs into the post-auth, it runs the post-auth processing. Which doesn't read the users file... as the users file is done only in the authorize section. You should be able to put authorized_macs.authorize in the post-auth section. That will make it process the users file, and do what you want. Alan DeKok. - List info/subscribe/unsubscribe?

Russell Mike wrote: All-In-MB counter works. Please note, when a user has downloaded his quota, counter do not force log off . The counter modules DOES NOT DO THAT. To see why, ask yourself what does FreeRADIUS see when the user has downloaded his quota? The answer is nothing. The users traffic doesn't go through FreeRADIUS, because FreeRADIUS isn't a router. What FreeRADIUS *may* see is an Accounting-Request for the user. Which contains the total traffic for the user. So if you want to do something when the users traffic is over the quota, you have to do it in the accounting section. You have to update the SQL database, and then check if the user is over quota. If so, send a Disconnect-Message, or exec a program to kick the user offline. Which basically means that initially authorization is done by SQL then max_all_mb, checks are only done once when the user makes the logon attempt and checks are never done again. Yes. That's what you've configured. If you want more, you need to tell the server to do more This is where i have failed.

Version 3.0.0 has been released
After many years of development, the FreeRADIUS team is happy to announce Version 3 of the world's most popular server. The release was delayed from June in order to track down and solve a number of last-minute issues. We'd like to thank all of the beta testers for helping with that process. The release announcement is available on the web site: http://freeradius.org/press/index.html#3.0.0 In short, it's simpler, easier to use, and better organized. Upgrading instructions are available here: https://github.com/FreeRADIUS/freeradius-server/blob/release_branch_3.0.0/raddb/README.rst As this is a major version, you CANNOT just use your 2.x configuration files. Sorry, but many of the new features require changes which aren't compatible with 2.x. See the LDAP and SQL modules for new connection pools, for example. The debug output is colorized, with yellow WARNINGS and red ERRORS. This should help people understand which messages are important and need attention. RADIUS over TLS (RadSec) is supported. This means RADIUS has actual security, instead of the 20 year-old MD5 weirdness. Many configuration errors are caught at startup, rather than run time. Helpful messages are printed, including a pointer to which character caused the error. The raddb/ directory has been re-organized. The files should now be easier to find, as they use a consistent layout. DHCP and VMPS are still supported, but their code has been moved to plug-in modules. We expect to continue this process for the 3.1 release. The goal is to move RADIUS to a plug-in module. The server will then be capable of handling many more protocols. We have a number of new protocols in development, and will be announcing them later this year. SNMP traps are now supported. You can trigger a trap when a home server goes down, and when it comes back up again! While supporting many new features, the code is almost 10% smaller than version 2.2. In addition, it has daily builds on multiple platforms, including automatic static source code analysis. This means that the code is smaller, more secure, and easier to maintain. We'd like to add a special thanks to the Samba project, for the talloc library. Many of the new features we made possible by talloc. We expect more features in the future. Alan DeKok.

Re: lifetime of dynamic clients
1. FreeRadius lacks the ability to actually run Nas's behind a link with a dynamic IP. Although not recommended, this software does not support a proper way of dealing with this. Nonsense. This is a fundamental limitation of the RADIUS protocol. If you want to use dynamic IPs, use a VPN, or TLS (RFC 6614) This is indeed a fake. I have added this in mysql in the nas table under the field community (described in ify /yfi setup). The connection actually works. I can (ab)use this field as much as desired Because RADIUS depends on source IP. Of course. RADIUS depends on IP addresses, not on Called-Station-Id. This is documented in the dynamic_clients configuration. Right at the top of the virtual server. Yes, I have read the documentation (multiple sources, google etc...) I was just wondering what happens when you use the raw module. It's not distributed with the server. So it's not a supported module. And no, I don't use it. And no, you haven't read the documentation. The files I mentioned *clearly* states that the dynamic clients use and cache the source IP. They say NOTHING about checking the Called-Station-Id for each packet. Is a client defined by a NAS or a user? RADIUS clients are defined by source IP. The documentation you allegedly read makes this clear. So there's no need to ask the above question... because the documentation already answers it. The output shows indeed when it goes through the the dynamic server section and once it is authenticated it only runs through the default (which is understandable) So... *nothing* else in the debug output is useful to you. I guess you've read it as carefully as you've read the documentation. Alan DeKok. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

Secondly I have read the documentation, but RTFM still appears to be the common way of responding (even after using Linux for over 15 years). So you read the documentation saying that clients are defined by IP addresses, and then asked whether or not clients are defined by NAS or by user. Did you (a) NOT read the documentation, or (b) read it and not understand it, or (c) read it, understand it, and ask a misleading question? Thirdly , the case below is a true real life situation, which does not only occur only for me, but also for other. Even though the module is not officially supported (maybe for the reason there are) it is in today's world . You can decide, be a bernstein (like qmail) or adopt to a real life situation.

I'm not really clear on the issue you're having, because your statements are contradictory. Am I allowed to get frustrated at that? And yes I have read the statements on caching , what is used and even the disclaimer that only the src ip is supported. So don't become patronising that I didn't.

If the only output after authentication is adding client xxx.xxx.xxx.xxx with shared secret it does not state a) lifetime b) anything else usefull. It shows the IP of the client. It does NOT say adding client keyed by Called-Station-Id See? The debug output says what it means, and means what it says. Because you're unwilling to take it at face value, you think it's useless. That says more about you than anything else. Now I am running radmin show client list and see the IP appear. I am now testing when it disappear.

Don't do that. Trying random things is *always* a bad idea.

No. You have to configure the ntlm_auth module, and the ntlm_auth
sub-section of the authenticate section. All of that is documented in
the deployingradius.com page.
See my comment earlier. Did I place the configuration at the right
sub-section?
I have no idea. You've been careful to say as little as possible, in
a manner which is as confusing as possible.
Yes, I saw the ntlm_auth configuration under modules/mschap and
modules/ntlm_auth. As stated in my first email, I am able to configure
freeRadius to authenticate against our Active Directory using
EAP-MSCHAPv2 (ntlm_auth) and I am looking to see if using EAP-GTC will
work as well.
It WILL work. Just set auth_type = ntlm_auth in the gtc
configuration. As I said.
As I mentioned earlier, I tried both auth_type = ntlm_auth nor ntlm_auth
= /usr/bin/ntlm_auth ... command execution, but that don't work.
So... rather than following instruction,s you're trying random things.
How about running it in debugging mode, as suggested in the FAQ, man

The reason we recommend it is that IT WORKS. If you're trying random
nonsense, you're wasting your time, and ours.
The reason I am asking the question of multiple challenges because I am
currently evaluating another vendor solution for multi-factor
authentication thru EAP-PEAP/TLS with EAP-GTC and the solution prompts 2
additional inputs during authentication. Here is the
link: https://www.duosecurity.com/docs/netmotion. I thought if they can
do it, freeRadius can do it as well.
The issue is the EAP-GTC specification, and the clients. Last I
recall, it didn't support multiple challenge-responses.
If it does, then it's possible to upgrade FreeRADIUS to do it. As

Read the gtc sub-section of eap.conf. It tells you how to make
EAP-GTC use a particular authentication method.
I tried to execute ntlm_auth passing
--password=%{User-Password}, but that didn't work as User-Password is
empty.
You tried *where*? That matters.
It says in eap.conf that GTC challenges the user with text and
the response from the user is taken to be the User-Password. Perhaps I
am executing ntlm_auth too early before GTC Password challenge is sent
out and received the response.
My questions are:
1. How can I configure freeRadius so GTC will work with ntlm_auth?
a) configure ntlm_auth as per the deployingradius.com docs, and the
examples in the config files
b) tell EAP-GTC to use ntlm_auth as per the examples in the gtc
configuration.
2. Is it possible to send subsequent GTC challenge in addition to
default Password challenge? If possible, how do I configure the
subsequent GTC challenge?
No. EAP-GTC is only challenge-response. It doesn't do multiple
challenges.

Ideally a step-by-step guide, in the style of the EAP docs on http://deployingradius.com/ - the documentation should include examples of an ISC configuration, and how it maps to a FreeRADIUS configuration - the documentation should include simple tests, and common problems to check - it should include any new scripts, etc. necessary to get it working. - any code / configuration will become part of the main FreeRADIUS releases - the documentation and worked examples will get hosted on the FreeRADIUS web site, and prominently linked from the main page - your name will go on everything - since my company is paying for it, all copyright will belong to Network RADIUS SARL. This is a request for *paid* work. I'm prepared to pay reasonable rates for this. And not the $100 bounty for 6 days work kind of nonsense, either. Please send email to me with your proposal, background, and price. I'll pick someone in the next week, and work behind the scenes to get this done. The hope is to crush that pesky ISC server.

Version 2.2.1 has been released.
After a long wait, we have released the 2.2.1 version of FreeRADIUS.
The focus of this release is stability. Minor features may be added,
but the goal is to increase system stability at the cost of missing
features.
People interested in major new features should look at the v3 release
branch. Our focus now is fixing the last few issues in v3, before
making a new release.
Once v3 has been released, there will be no further new development on
Version 2. Bug fixes and security issues will be addressed for three
(3) years after v3 has been released.
The change log for v2.2.1 is as follows:

Feature improvements
* Updated dictionaries for alcatel, broadsoft, bskyb, dlink, meru,
telkom, trapeze, proxim, zeus, rfc6677, 6911, and rfc6930.
* Added %{randstr:..} support. Creates random strings in a
controllable format.
* Added operator support to rlm_python
* Added %{hex:...} for hex version of raw attribute data
* Added %{sha1:...} for SHA1 hashing of data
* Added %{base64:...} for raw attribute data (e.g. 32-bit IP addr),
and %{tobase64:...} for the printable string form (e.g. 1.2.3.4),
and %{base64tohex:...} to convert a base64 string to a hex string.
* rlm_expr is now responsible for registering many of the xlat
expansions. This is cleaner than bundling them all in the server
core. You should ensure 'expr' is listed in instantiate to ensure
correct operation of xlat expansions.
* Use correct terminology when printing errors regarding request/
response/message authenticators.
* Added keytab support to Heimdal Kerberos. Patch from Ryan Steinmetz.
* radsqlrelay does multiple INSERTs in one transaction.
Patch from Uwe Meyer-Gruhl.
* Run Post-Proxy-Type Reject {} if the upstream server rejected the
request.
* On startup, the server checks if it was linked with the correct
OpenSSL libraries. If not, it errors out. This prevents later
crashes in OpenSSL, due to library incompatibilities.
* Added radmin command hup main.log, to re-open the log files,
without HUPing any other part of the server.
* Added support for EAP-Key-Name. See raddb/sites-available/default,
and look for comments mentioning EAP-Key-Name. MacSec now works.
* Added support for hex numbers (0x...) to %{expr: ...}
* Backported TLS client certificate validation from 3.0.0.
* Run Post-Auth for EAP inner-tunnel methods.
* Added more RFCs
* Added show config path to radmin. You can now examine any
configuration item in a running server.
* Added TLS-Client-Cert-X509v3-Extended-Key-Usage for TLS-based EAP
methods. It is set automatically from the fields in the certificate.
* Add CRLCP attribute in certificate creation script. Windows phones
require it. Patch from Alan Buxey.
Bug fixes
* Skip OCSP if there's no host / port / url, with soft_fail
* Properly decode AT_IDENTITY in EAP-SIM. Patch from Iliya Peregoudov
* Thread max_queue_size has better bounds checking.
* Use correct variable for warning message if the user misconfigures
the server.
* radtest is more generous about parsing ppphint
* radeapclient now accepts -4 and -6, just like radclient.
Patch from John Dennis.
* Ignore .rpmnew and a bunch of other files when loading config
files from a directory.
* Wait for child threads before exiting. This prevents errors on
exit, but may increase exit time if databases are blocked!
Patch from Iliya Peregoudov.
* Wrap rbtree calls in mutexes in rlm_cache to prevent memory
corruption. Patch from Phil Mayers.
* Port fix for %{3GPP-*} expansion from master branch.
* Fix sample certificate scripts when multiple client certs are
made
* Track return code priorities across if/else/elsif in unlang.
Closes #107
* In debug mode, print out DHCP options when sending a DHCP packet.
* Fixes to the redis modules from Brian Candler
* Print better debug message for LDAP operations error
* Fix a number of minor issues as found by Coverity
* Frees module config in order to prevent occasional crash on exit
* Update DHCP debugging messages to make it clearer what's
going on.
* Print multiple DHCP options the correct number of times in
debugging mode
* On debug builds, don't dlclose() modules when '-m' is used.
This allows valgrind to show module symbols.
* Don't count Status-Server packets in Access-Request statistics
* Minor cleanups to debug output
* Be more careful handling module configurations to avoid crash
on otherwise clean exit.
* For raddebug, correctly set the group of the output file.
* renamed dhclient to dhcpclient. People who install it
shouldn't have their systems broken.
* for EAP-TLS methods, random_file is no longer required.
OpenSSL already reads /dev/urandom.
* Fix Suse and Redhat scripts. Patches from Fajar Nugraha.
* Minor bug fix for base64 decoding.
* Allow two consecutive WiMAX TLVs of the same number.
* Remove requirement that User-Name has to match MS-CHAP-User-Name.
I18n issues means that the character sets could

So... you're not using LDAP.
Let's start from the beginning. What, exactly are you trying to do?
What have you done? Why did you think that would work?
Be specific.
In short, you *can't* do LDAP fail-over if you're using ntlm_auth.
That's because ntlm_auth interacts with Samba. And you have *no* LDAP
configuration in the authorize section. And Samba takes care of
Samba-related fail-overs, so LDAP isn't necessary.
It's like you're asking for flying lessons, and showing up with a
bicycle. There's a bit of a disconnect somewhere.

Re: [ANN] Version 3.0.0-rc1
Stefan Winter wrote:
The idea is that make install is not supposed to touch my production
config in any way. I don't want it to generously add directories without
me knowing.
Honestly, the simplest might be to edit Make.inc, at the top where it
defines raddbdir and modconfdir:
ifeq $(raddbdir)
raddbdir= ${sysconfdir}/raddb
modconfdir = ${sysconfdir}/raddb/mods-config
endif
Then, do:
$ ./configure ...
$ make
$ make -Draddbdir=/tmp/garbage install
All of the raddbdir stuff will get installed to the /tmp/garbage
directory. The binaries will be built with the correct paths, and
installed in the correct locations.
It was easy to tell it to back off earlier (even easier in v2 - just mv
source/raddb/ out of the way), but now for some reason the old v3-style
mechanism doesn't work any more.
Well... the build system has changed *completely*.
I guess I could create the mods-config/ dir in my production config dir
and it would make the symptom go away.
I still found it worth reporting that some messing-around with the
config dir is going on/attempted even when the source dir is told not to
do that.
Because the rules for install to config dir are scattered through
the source, and not all in raddb. So when you nuke raddb, you don't
delete all of the rules.
It's not nice if one module makes assumptions about a part of the
directory structure it doesn't control. Nothing stops me from deploying
a raddb with the configs lying in
raddb/modules-configuration-information/ and it would be very undue if
the stock build process bails out on failure then during a subsequent
installation.
Well... if you want to create a non-standard configuration, it's up to
you to do the work.
The default install process assumes that the installation is... a
default one. The customization is done via the paths at the top of the
Make.inc file. If you want to change *internal* paths, then all bets
are off. My only answer is Good luck!

The post-proxy stage has NOTHING to do with the home server. If the
home server rejects the request, the issue is WAY before the
post-process stage.
I see that eap needs be invoked if using
proxy_tunneled_request_as_eap = no
Does it actually need to NOT be there for
proxy_tunneled_request_as_eap = no
No.
See my reply to Phil. You need to set:
proxy_tunneled_request_as_eap = no
in eap.conf, peap{} subsection.

For boolean does anyone know if they really mean a standard 32bit integer with the values 0/1, or if they're wanting a single byte with the values 0/1, or whether it's some other cisco craziness? My guess is that it's a single byte. In v2.2.x, that's byte type. Alan DeKok. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

Re: how to limit the repeating ldap lookups
Martin Kraus wrote:
I'm using TTLS+TLS.
Then what are you looking up in ldap?
I can see that the eap { ok = return } automagically skips to the
authentication section but the first two access-requests in the session cause
it to return updated status so the ldap lookups are executed.
I assume there isn't much I can do about that, right?
Sure. You can look at the debug output, see what's different between
packets N and N+1, and use those differences to selectively run ldap.
I then have a separate problem with the inner-tunnel where the inner-eap never
returns ok in the authorization section so it keeps on doing the ldap lookups.
in the session I have it did 9 separate passes which together with the outer
tunnel is 11 ldap passes which in my case is more then 30 ldap lookups for a
single user login.
Again, look at the debug output.
There are also these warnings in inner-tunnel
WARNING:
!!
WARNING: !! EAP session for state 0xfa098d01f80a8033 did not finish!
WARNING: !! Please read http://wiki.freeradius.org/Certificate_Compatibility
WARNING:
!!
but the inner tls session seems to be still progressing fine since the last
warning is right before the last access-request which results in the
access-accept for the user.
Read it again. The ONLY time that message is produced is when the EAP
session doesn't finish. There are likely 2-3 failed attempts before one
success. If you only look at the succes...
Is there something I can do about the 9 lookups in the inner-tunnel server?
I'll have a look at the rlm_cache as well but I'm just curious as to why is it
happening.
Because that's what you told it to do. The server is pretty dumb that
way.
Again, look at the debug log to see what's happening. *WHY* are you
doing LDAP lookups at all? Can you not delay them?
And rlm_cache should help a lot, too.

Re: Groups in active directory and checks in MySQL
Atomikramp wrote: I'm in a situation now where i can successfully retrieve group membership of users in the active directory LDAP tree using rlm_ldap, and check them against files. OK. so if i have a user with memberOf attribute set to groupA and i set in the raddb/users the following entry: DEFAULTLdap-Group == groupA, Auth-Type := Reject Reply-Message = Not Allowed. i successfully deny access to that user. That should map directly to the SQL tables. Since i'm already using MySQL for storing accounting informations i was really interested in being able to use the same backend (mysql) also for performing checks against groups. If i perform checks against usernames using the table radcheck they work properly (users retrieved from the LDAP backend), i've tried setting a radcheck like the following: userA Max-Daily-Session := 7200 and after 2 hours the user is unable to authenticate to the NAS because the time allowed has expired. But i cant seem to be able to do the same thing with the groups. Post the debug output. And what do you have in SQL? i've configured sites-enabled/default like this: Note that the FAQ, README, man pages, and web pages ALL say to post the debug output. We really don't care about the configuration. It doesn't show what happens when the server receives a request. Alan DeKok. - List info/subscribe/unsubscribe?

Re: debian, wpa_supplicant, TTLS/TLS working, PEAP/TLS fails
Phil Mayers wrote: PEAP/MSCHAP is *always* PEAP/EAP-MSCHAPv2 IIRC. Unlike TTLS there's no bare MSCHAP variant, because there's no spec for how to derive the MSCHAP challenge from the TLS master secret. FWIW: PEAP is TLS + inner EAP. That's why there's no PAP / CHAP / MS-CHAP inside the tunnel. It *has* to be EAP. Microsoft could solve a lot of problems right now by providing an API to execute EAP-PWD with the NT-hash variant of the secret against an AD controller. Instead, we're all flailing around with the very best of early 90s crypto protecting our wireless :o( Pretty much. Alan DeKok. - List info/subscribe/unsubscribe?
