..::Restrict local users::..
by Alfonso Alejandro Reyes Jiménez 25 Jun '11

25 Jun '11

Hi Everyone. we would like to know if there's a way to reject access to the local users, that's because we discover that if you have a system account you may login on the radius server. I have the teory that if we use the rlm_passwd module we can reject the access to the "local group", I search on the man rlm_passwd file and it has examples of the configuration. The only thing that I don't understand is how radius know which file to check. I mean if I put a file with our group information, how can I tell radius to check that file? I have the group file on the /etc/ and the smbpasswd example on /etc/raddb/modules/ I've checked all the raddb directory files looking for any option without luck. What am I doing wrong? Any advice will be appreciated. Alfonso.

Authentication Problem
by john decot 24 Jun '11

24 Jun '11

Hi , I have been using freeradius-server-2.1.10 . Dialupadmin is using for web based administration. It was working fine till yesterday. I have changed added attribute to check Max-All-Session. Then I have face problem of No authenticate method (Auth-Type) found for the request: Rejecting the user however the authorized section is working fine. After googling i have check with option default Auth-Type = Local but it was not success. this error occurs for new create user only , old user are authenticating normally. I have revert back my changes with removing attribute to check Max-All-Session but still the error exists. Please advise me. Regards, John

simultaneous-use with checkrad
by tyllerd＠gmail.com 24 Jun '11

24 Jun '11

Hi I know its not the best way to do it but I would really like to use simultaneous-use attribute without using the checkrad script. meaning the radius server does the check in radacct table and if the check is true, deny authentication. is this possible? I am using sql and in the radgroupcheck table i have simultaneous-use := 1 and in sites-enabled/defaults under session I have sql selected and the query is present in sql/mysql/dialup.conf is it possible for the freeRADIUS server to do this? Thanks in advance -- View this message in context: http://freeradius.1045715.n5.nabble.com/simultaneous-use-with-checkrad-tp45… Sent from the FreeRadius - User mailing list archive at Nabble.com.

Migrating to threaded rlm_perl
by Energ 24 Jun '11

24 Jun '11

Hi everyone! Please, help me with understanding of concept how to rewrite my perl module to work with threaded perl. Now it looks like this: my %options_pools = (create=>1, exclusive=>0, mode=>0644, destroy=>1); tie my %pooldb, 'IPC::Shareable', $pools_glue, { %options_pools } or die "Tie failed: $!\n"; ... code to fullfill shared segment ... sub post_auth { ... $RAD_REPLY{'Framed-IP-Address'} = "$pooldb{$rpool}{$RAD_REQUEST{'Calling-Station-Id'}} ... %up= fetch_url("$https_host","$https_xml","$RAD_REQUEST{'User-Name'}"); } sub fetch_url { ... using Net::HTTP i retrieve some additional stuff from billing. ... } While non-threaded perl it works as expected. But threading breaks creation of Shared memory (cuz it want to do it for every thread). I also wonder, do i need to post &fetch_url inside CLONE sub or not. So, the main question: is there any part of code in rlm, that suppose to run only once ( create shared memory in my situation) or how to correctly solve problem with IPC within the confines of freeradius. Thx! -- View this message in context: http://freeradius.1045715.n5.nabble.com/Migrating-to-threaded-rlm-perl-tp45… Sent from the FreeRadius - User mailing list archive at Nabble.com.

Dynamic Clients IP Best practice?
by Brent Wilkinson 24 Jun '11

24 Jun '11

I unfortunately have a large amount of hotspots that are behind dynamic ip's. We have tried to get as many of them onto statics as possible but are having issues with that. After having read through a few dozen different threads and readmes does freeradius have something that has been put into place to address this?( I assume the answer is no or I glazed over while reading and missed the answer) . If there is no built in feature is there a best practice for this? Reverse DNS and / or VPN tunnels are the 2 solutions I can think of that would secure the nas check. Is there something else I am missing I can read up on and look into? Thanks Brent

Credentials format in Windows suplicant
by joanroldan 23 Jun '11

23 Jun '11

Hi everybody, I have take a look to this post: http://freeradius.1045715.n5.nabble.com/MSCHAP-Authentication-Issue-td27851… And I totally agree with the behaviours described in the table. I have been experiencing the same. If I type the credentials on prompt of Windows supplicant like MYDOMAIN.COM\user password The request is accepted: Fri Jun 10 15:58:51 2011 : Info: ++[eap] returns ok Fri Jun 10 15:58:51 2011 : Auth: Login OK: [IRTA_NT\\jroldan/<via Auth-Type = EAP>] (from client WLC_SSCC port 1 cli 00-26-B6-59-F1-EA) But if I type user(a)mydomain.com password I get the next info: Fri Jun 10 16:11:52 2011 : Debug: Exec-Program output: Logon failure (0xc000006d) Fri Jun 10 16:11:52 2011 : Debug: Exec-Program-Wait: plaintext: Logon failure (0xc000006d) Fri Jun 10 16:11:52 2011 : Debug: Exec-Program: returned: 1 Fri Jun 10 16:11:52 2011 : Info: [mschap] External script failed. Fri Jun 10 16:11:52 2011 : Info: [mschap] FAILED: MS-CHAP2-Response is incorrect Fri Jun 10 16:11:52 2011 : Info: ++[mschap] returns reject Fri Jun 10 16:11:52 2011 : Info: [eap] Freeing handler Fri Jun 10 16:11:52 2011 : Info: ++[eap] returns reject Fri Jun 10 16:11:52 2011 : Info: Failed to authenticate the user. Fri Jun 10 16:11:52 2011 : Auth: Login incorrect (mschap: External script says Logon failure (0xc000006d)): [jroldan(a)irta.es/<via Auth-Type = EAP>] (from client WLC_SSCC port 0 via TLS tunnel) I assume my configuration is fine (extracted from deployingradius.com) because its working by typing credentials in NT format. As the configuration of freeradius is for eduroam purpose it would be nice that user enter the credentials like user(a)domain.com, and in function of the domain the request would be proxied or not. Is is possible to use this format in spite of NT-domain?

pairfind segmentation fault

Hi, i m writing a module2 for freeradius 2.1.10 on linux 2.6.18-194.el5PAE. this is the code: vp = pairfind(request->packet->vps,PW_USER_NAME); DEBUG("Found username = %s",vp->data.strvalue); // create and add the cleartext-password vp_clear_password = pairmake("Cleartext-password","smart",T_OP_SET); pairadd(&request->config_items, vp_clear_password); // create and add the callback-id vp = pairmake("callback-id","0702005010701059",T_OP_SET); pairadd(&request->reply->vps,vp); but the pairfind is giving segmentation fault: Program received signal SIGSEGV, Segmentation fault. 0x00b2879b in authorize (instance=0x8184460, request=0x81bbc68) at ../main.c:135 135 vp = pairfind(request->packet->vps,PW_USER_NAME); I have no idea what the problem is. What is the different between pairmake and radius_paircreate ? when am i supposed to use pairfree ? please let me know what the problem is. thanks!!

2.1.x 34c68ba8: freebsd 7.x: segfault/internal error in select()
by Russell Jackson 23 Jun '11

23 Jun '11

I'm getting a segfault on exit after logging this to syslog: Exiting due to internal error: Failed in select: Invalid argument kernel: pid 87513 (radiusd), uid 133: exited on signal 11 select(2) indicates that EINVAL is returned when the timeout is invalid (being negative or too large). I modified the error message to include the value of "when" in lib/event.c. I then got: Exiting due to internal error: Failed in select: Invalid argument: wake 4sec, 1000000usec I suspected that tv_usec needs to be < USEC, so I kluged the code to subtract 1 from when.tv_usec if it's >= USEC. So far, I haven't had any more crashes. Commit d8084182 seems to be when this code was changed last, and I didn't have this problem before on 2.1.x. https://github.com/alandekok/freeradius-server/commit/d8084182bbec453712a96… -- Russell A Jackson <raj(a)csub.edu> Network Analyst California State University, Bakersfield

Returning Multiple Reply Items problem ?
by Robert Roll 22 Jun '11

22 Jun '11

I seen to have encountered a problem with returning multiple reply-item attributes ? They seem to be found, but only some arereturned... see the debug snippets below... It seems if they have the same name, only one of them gets returned ? However, for the Cisco-AVPair attributes, it is very common to need to define many of them ? Is there a way to get them all returned ? Currently running 2.1.10 .. Thanks, Robert i.e. ##### Seem to be found in Directory ##############3 [ldapADutVLANs] looking for reply items in directory...
