FreeRADIUS 3.0: Segfault in rlm_detail
by Julius Plenz 06 Mar '14

06 Mar '14

Hi, I'm trying to upgrade my config to FreeRADIUS 3.0, but I get reproducable segfaults in the `rlm_detail' module. I send a simple packet (User-Name, User-Password) via `radclient', and the server immediately crashes: $ bin/radiusd -xx -f -l /dev/stderr -t ... (0) auth_log : expand: "/server/devel/server/log/client/%{Client-IP-Address}/auth-%Y%m%d" -> '/server/devel/server/log/client/XXX.XXX.XX.XX/auth-20140304' (0) auth_log : /server/devel/server/log/client/%{Client-IP-Address}/auth-%Y%m%d expands to /server/devel/server/log/client/XXX.XXX.XX.XX/auth-20140304 (0) auth_log : Acquired filelock, tried 1 time(s) (0) auth_log : expand: "%S" -> '2014-03-04 14:41:14' Bad talloc magic value - unknown value [Backtrace follows] The auth_log is defined in the detail module config: $ cat etc/mods-enabled/detail ... detail auth_log { filename = ${radacctdir}/%{Client-IP-Address}/auth-%Y%m%d permissions = 0600 dir_permissions = 0700 locking = yes header = "%S" log_packet_header = yes suppress { User-Password } } ...

Thanks in advance, Julius P.S.: I'm using the v3.0.x branch from a few days ago, namely 80eee20b9. Compiling against the tip of v3.0.x, eb3bfda, is not possible any more: $ make CC src/lib/cbuff.c In file included from <command-line>:0: /server/devel/src/freeradius/src/freeradius-devel/build.h:84:6: error: #error Failed determining endianness of system make: *** [build/objs/src/lib/cbuff.lo] Error 1

FreeRADIUS has been removed from Debian "testing", for reasons that aren't clear. http://packages.qa.debian.org/f/freeradius.html Anyone willing to help? Alan DeKok.

User and group attributes
by Lorenzo Milesi 06 Mar '14

06 Mar '14

Hi. I know it's a stupid question but so far I couldn't manage to dig it out. I'm using FR2 with MySQL backend. All my users belong to one or more group. I usually set the Idle-Timeout attribute using the radgroupreply table, and it works great. For a minority of users I'd like to override this attribute to a different value, but I cannot have FR reply as I wish. Current situation: Radcheck: USERA MD5-Password := somemd5hash Radusergroup: USERA c_gvt 30 Radgroupreply c_gvt Idle-Timeout := 3800 This works fine and replies 3800. If I add USERA Idle-Timeout := 100 to radreply it will still reply 3800. Then I checked manpage of USERS [1] so I changed: Radreply: USERA Idle-Timeout := 100 Radgroupreply c_gvt Idle-Timeout = 3800 but the reply is always the same. What am I missing? thanks [1] http://freeradius.org/radiusd/man/users.html -- Lorenzo Milesi - lorenzo.milesi(a)yetopen.it YetOpen S.r.l. - http://www.yetopen.it/

dailycounter isnt started
by Sanity Computers 06 Mar '14

06 Mar '14

Hi All, I've tried the default FR2.x dailycounter code and loads of other examples yet. It seems the max-daily-session time is been ignored and debug shows no sign of the dailycounter. If I log out and log back in the counter does work and sends the timeout response, I can see the dailycounter lines in debug. So dailycounter works when there is at least 1 session which suggests most of the setup is correct. I suspected the dailycounter query is wrong but the query isn't even started. except on a second session. Can anyone see why it would not work on the very first login? Regards Jim

About proxy mode, when all home servers are dead
by regulus regulus 06 Mar '14

06 Mar '14

Dear All, I have a FreeRADIUS 2.2.3 run in proxy mode to 2 home RADIUS servers in failover mode. The problem I face now is that when both home RADIUS servers are dead, FreeRADIUS will send a reject to NAS >>ERROR: Failed to find live home server for realm net-yan.com>>There was no response configured: rejecting request 2 When NAS receive a reject, it won't failover to another redundant RADIUS. Is there a way to configure FreeRADIUS such that it will not send another response back to NAS when all home RADIUS are dead?I have been studying the "do_not_respond" policy, but not sure how to use it in this case.. NAS --> primary: my FreeRADIUS --> Home RADIUS --> secondary: another RADIUS --> Home RADIUS Thanks a lot! Regards,Leo

radtest works, connection via wlan fails
by Thorsten Bresges (web) 06 Mar '14

06 Mar '14

Hello, I am new to freeradius. I try to set up freeradius for an high school. I am using FreeRADIUS Version 2.1.12 for host x86_64-pc-linux-gnu on an debian system. Freeradius is working with the users file and clear text password. Now I would like to put the users in a myslq database. I insert two test accounts: One with an cleartext password and one with an MD5 password (test account "ilka"). I did the "guide/SQL HOWTO" - except I just entered the neccesary entries for "fredf" in the howto. When I try "radtest" everything works fine: The account in the users file and the twe accounts in mysql are accepted. Afterwards I tried to connect from my Mac over WLAN and an accesspoint to the freeradius server. It worked fine with the account in the users file. But when I tried it with the accounts that are stored in the mysql database: Neither the cleartext password nor the md5 password account works - even though this accounts worked with radtest. What do I wrong? Do I have the wrong idea? Here is a part of the freeradius debug log. First you see my test account is working with radtest. The second try it is not working via wlan and the access point. Thank you for your help.

Behavior of FreeRADIUS auth when SQL backend becomes inaccessible
by Patrick Wagner 05 Mar '14

05 Mar '14

Hello, we've got a problem with FreeRADIUS / rlm_sql behavior that prevents us from enjoying a fully redundant RADIUS service, consisting of 3 FreeRADIUS servers, probably because of compounded mistakes / misunderstandings in our configuration that I've attached at the bottom of this post. Setup: - each of the 3 servers consists of a FR instance and a MySQL instance that contains all auth data and the radacct table to store acct data - each FR instance connects to its local SQL instance only, there's no redundant or load-balance setup required - going that route and have FR try to connect to the SQL instance on one of the other nodes in case of errors with the local one would also solve our problem, but we deem it unnecessary if FR was able to handle a failed SQL connection "properly" - the SQL nodes are configured as Galera multi-master cluster, so any node is operating on the same set of data -> this means every node should work perfectly fine on its own, which is why we don't think we need to implement the redundancy options that FR offers. If SQL is unavailable before we start FR, FR refuses to start and exits immediately after it finds out it cannot connect to the local SQL instance, with "Instantiation failed for module sql_localhost". This behavior is perfectly fine because it means that any NAS client sending requests to that particular FR node will find that the node does not respond, and the client will retry the request with the other RADIUS servers it knows of and hopefully, at least one of them will answer. However, if we start FR while and subsequently shut down the SQL instance, rlm_sql returns a fail, "SQL query error; rejecting user", and FR subsequently sends a REJECT response to any NAS request it receives, which is not at all the behavior we'd like to see as it means that any NAS querying this particular FR node will deny all requests instead of retrying the request with another node. I've seen a post on this list by Alan DeKok suggesting that "fail = ok" (or = invalid or whatever we should use in this case) is proper unlang or at least was proper syntax back in 2007, but with FR 2.1 (the respective version packaged with Ubuntu 10.04 LTS and CentOS 6.5) I was unable to start FR with such a statement added in either the "authorize" or "post-auth" section, declaring "Unknown action 'invalid'" when parsing the config. Respective thread which I hoped would give me some pointers: http://lists.freeradius.org/pipermail/freeradius-users/2007-December/024055. html Reply by Alan DeKok which I went on to try, unsuccessfully, with the error message quoted above: http://lists.freeradius.org/pipermail/freeradius-users/2007-December/024059. html Actually, FR's current behavior is a bit more irritating to us because we need to use a custom huntgroup SQL query that we placed in an "update request" section right before we (try to) query SQL for auth in the "authorize" section, but instead of two times "fail" we get two different error codes from the two statements when SQL is unavailable: - "++ [request] returns notfound" and later - " ++[sql_localhost] returns fail" Do we need to suppress / rewrite both of them? Suppressing the first one is impossible, I think, because in "update request" apparently FR doesn't differentiate between a query that was executed returned but returned an empty result, and a failed query (because SQL was unavailable). The invocation of sql_localhost, right below, does differentiate, as it returns fail instead of notfound. What is the proper way to allow the NAS clients to fail over to another FR node altogether instead of getting misleading and in most cases outright wrong information ("Invalid user" is what FR tells the NAS) from FR? Can we make FR just not reply to the request at all in these cases, or send a request that signals to the NAS that it should try the FR node next door instead because this FR node is unable to make any definitive statement? And finally, we're forwarding exactly one particular realm to another RADIUS server outside of our administrative control, and while any information FR needs to be able identify these requests as "to-be-proxied" is configured in plaintext files and thus should continue to work if SQL fails, requests for this realm also fail as soon as we shut down SQL, because the explicit REJECT from SQL makes FR not even proxy the request to the home server before telling the NAS that the Login request should be denied. Why does FR try to run the query against SQL (i.e. its own authorize section) at all if it knows from config that it should simply forward the request (unmodified even, we don't use pre-proxy or post-proxy at all) and wait for the reply of the home server for this particular realm? The last issue doesn't occur if we put a redundant {sql_localhost; handled} block instead of the single "sql_localhost" statement in the auth section, but I don't know WHY it works (it probably causes side effects we don't want), or rather, I figured that somehow the reseller request always gets checked against the local SQL database first (which it shouldn't or at least doesn't need to waste any CPU cycles on as it will never find anything in there about the reseller's customers), no matter whether the SQL connections works or doesn't work, but somehow a "notfound" from SQL leads FR to finally proxy the request to the reseller RADIUS server and get a proper answer, while a "fail" from SQL somehow skips the proxying step and outright denies the request. Obviously we don't want the proxy requests to ever get checked locally - this would solve this issue completely. I've attached the configuration we use currently below - if you need radius -X output for a particular scenario, let me know. - Patrick Wagner __________________________ Configuration of the only sites-enabled/ site document: authorize { update request { Huntgroup-Name := "%{sql_localhost:select groupname from radhuntgroup where nasipaddress=\"%{NAS-IP-Address}\"}" } preprocess chap mschap realmraute # realms are differentiated by #suffix eap { ok = return } sql_localhost # the following allows reseller requests to get proxied to the correct home server, but with unknown side effects # redundant { # sql_localhost # handled # } expiration logintime pap } authenticate { Auth-Type PAP { pap } Auth-Type CHAP { chap } Auth-Type MS-CHAP { mschap } unix eap } preacct { preprocess acct_unique realmraute } accounting { detail { fail = 1 } unix radutmp sql_localhost attr_filter.accounting_response } session { sql_localhost } post-auth { exec Post-Auth-Type REJECT { attr_filter.access_reject } } pre-proxy { } post-proxy { } ______________________ Configuration of radiusd.conf: prefix = /usr exec_prefix = /usr sysconfdir = /etc localstatedir = /var sbindir = ${exec_prefix}/sbin logdir = /var/log/freeradius raddbdir = /etc/freeradius radacctdir = ${logdir}/radacct name = freeradius confdir = ${raddbdir} run_dir = ${localstatedir}/run/${name} db_dir = ${raddbdir} libdir = /usr/lib/freeradius pidfile = ${run_dir}/${name}.pid user = freerad group = freerad max_request_time = 30 cleanup_delay = 5 max_requests = 1024 listen { type = auth ipaddr = 2.2.2.2 port = 1645 } listen { ipaddr = 2.2.2.2 port = 1646 type = acct } listen { ipaddr = 192.168.5.2 port = 1645 type = auth } listen { ipaddr = 192.168.5.2 port = 1646 type = acct } hostname_lookups = no allow_core_dumps = no regular_expressions = yes extended_expressions = yes log { destination = files file = ${logdir}/radius.log syslog_facility = daemon stripped_names = no auth = no auth_badpass = no auth_goodpass = no } checkrad = ${sbindir}/checkrad security { max_attributes = 200 reject_delay = 1 status_server = yes } proxy_requests = yes $INCLUDE proxy.conf thread pool { start_servers = 5 max_servers = 50 min_spare_servers = 3 max_spare_servers = 10 max_requests_per_server = 0 } modules { $INCLUDE ${confdir}/modules/ $INCLUDE eap.conf $INCLUDE sql_localhost.conf $INCLUDE sql/mysql/counter.conf } instantiate { exec expr expiration logintime } $INCLUDE policy.conf $INCLUDE sites-enabled/ _________________ Configuration of proxy.conf: proxy server { synchronous = no retry_delay = 5 retry_count = 3 dead_time = 120 default_fallback = no post_proxy_authorize = no } realm resrealm(a)domain.tld <mailto:resrealm@domain.tld> { type = radius authhost = 10.10.10.10:1645 accthost = 10.10.10.10:1646 secret = respw nostrip } realm LOCAL { type = radius authhost = LOCAL accthost = LOCAL }

Fwd: LDAP + CHAP
by Adam Seed 05 Mar '14

05 Mar '14

Hi all, I have a freeraidus server set up which uses an openLDAP back for its users and groups while it works fine for PAP passwords, it seams most clients are wanting to use CHAP. I have read that CHAP passwords will not work however on the faq its says; ' There are however provisions to extract the user password from the LDAP and make it available to the server core and the chap module' (http://wiki.freeradius.org/guide/faq) How is this done/setup? Thanks Adam

Questions about proxying to other servers over TLS
by stefan.paetow＠diamond.ac.uk 05 Mar '14

05 Mar '14

Hi, I have a quick question... Am I correct in saying that if I want to do all my proxying over TLS to another server, I have to define the default realm in /etc/raddb/sites-enabled/tls and comment it out in proxy.conf? And additionally, I have to define the proxy server as a client in the "clients radsec" section and as a server further down in the file?
