radiusd process vanishes on higher load
by Christian Hofstädtler 13 May '08

13 May '08

Hello! I'm using a FreeRadius setup (V 1.1.3-3 from Debian etch) with the MySQL Backend for authorize and accounting. RADIUS packets are coming from another company, which /probably/ has a Proxy for their delivery front-end servers. This setup usually works fine, but on some days I see spikes in the log, and the radiusd process vanishes; needing a restart. I've set: max_request_time = 5 cleanup_delay = 5 max_requests = 4096 sql.conf: num_sql_socks = 256 nas: nastype = other Usually, there will be a few 'stop packet with zero session length' log lines, about 1 per second or fewer. At problem/spike time, I see a lot more of these 'stop packet with zero session length' stuff (about 30 per second); and this too: Info: The maximum number of threads (256) are active, cannot spawn new thread to handle request Additionally, one of these things happen: 1) radiusd process vanishes without a log entry. 2) Error: Dropping request (4097 is too many): from client nasname:57426 - ID: 174 Info: WARNING: Please check the radiusd.conf file. ?The value for 'max_requests' is probably set too low. 3) Error: Internal error processing module entry And radiusd usually vanishes after this. With Option 3 I usually also see MySQL DB connection problems, but not all the time, and they are not always fatal (?). So - am I missing something? Is this just a very long spike (can take 10 minutes to a few hours); Are there any counters in FR that I could track? (like packets per second, etc.) Thanks, Christian -- Christian Hofstädtler InQnet GmbH Praterstraße 31 A-1020 Wien Tel.: +43 1 212 7650 523 Fax.: +43 1 212 7650 610

Thank you kalik
by johnson elangbam 13 May '08

13 May '08

hi kalik, After a long pause, I've successfully done my authorization of my radius server by using digest and perl authentication in mixed mode, as per your advice I put the digest entry first before the perl authentication in the default file, and after that I've put a line of perl code RAD_CHECK{'Cleartext-Password'} = $mypassword, where the password is fetch from the database. And finally the server starts reading the cleartext password and starts calculating the md5 encryption and sucessfully authorized a user. Lastly, I thank to all the members of this forum who are dedicated here to help solving the complex problem in a complicated environment, especially Evan Kalik who is much envolved, regarding my problems of not getting my digest attributes. Thanking you for your valuable time and consideration. With Regards, Johnson Elangbam

0 Session Length, radrelay or Freeradius causing issues
by Etienne Pretorius 13 May '08

13 May '08

Hello List, I have asked this before (http://readlist.com/lists/lists.freeradius.org/freeradius-users/1/7788.html) and Alan DeKok did say that I should place those accounting packets in a different Acct-Type, but that was when I did not wish to log the information but I now need to log the information and replicate to all radius servers. I need to know why the radrelay application stops replacation when it comes across a 0 session length packet. This morning I found a 40Mb backlog file for each server and realised that it was the 0 session-length packet again. I know FreeRadius does complain about it but it still logs this accounting packet into the sql database. So is it because FreeRadius indicates that an error (0 Session Length?). If so could I not just somehow tell FreeRadius to stop complaining and just accept the stupid packet. (As I am passing configurable triggers via 0 session length radius packets). -- Kind Regards Etienne Pretorius

Hi! Is it possible to run freeradius in debug mode to have all debug (clients request) information in log file. It is not usable to have open console with freeradius -Xf command. Thanks Alexey

OT: java radius client libraries?
by Alex French 13 May '08

13 May '08

Hi guys, Sorry if this is slightly OT but I'm hoping someone can advise on an open-source radius client library in Java for integration with another project that will be talking to a freeradius server. I have found two, jradius and tinyradius, but jradius does not seem to be in active development. Has anyone used either of these or something else, preferably with a freeradius server? Thanks, Alex

Referencing Ldap-Group in unlang
by Jason Alderfer 13 May '08

13 May '08

Hi all, I would like to convert the following users file entry to unlang code in 2.0.4. DEFAULT Ldap-Group == "cn=not_student,ou=n,o=emu" Tunnel-Type = "VLAN", Tunnel-Medium-Type = "IEEE-802", Tunnel-Private-Group-Id = 6 But after reading the unlang man page and trying it several ways, I can't figure out how to duplicate this functionality. The above users file entry causes this in the debug output: rlm_ldap: Entering ldap_groupcmp() expand: o=emu -> o=emu expand: (|(&(objectClass=GroupOfNames)(member=%{control:Ldap-UserDn}))) -> (|(&(objectClass=GroupOfNames)(member=cn\3dalderfjh\2cou\3dis\2cou\3dn\2co\3demu))) rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in cn=not_student,ou=n,o=emu, with filter (|(&(objectClass=GroupOfNames)(member=cn\3dalderfjh\2cou\3dis\2cou\3dn\2co\3demu))) request done: ld 0x81a5118 msgid 29 rlm_ldap::ldap_groupcmp: User found in group cn=not_student,ou=n,o=emu But so far none of the syntax below has invoked ldap_groupcmp(). if ( Ldap-Group == "cn=not_student,ou=n,o=emu" ) { if ( control:Ldap-Group == "cn=not_student,ou=n,o=emu" ) { if ( "%{Ldap-Group}" == "cn=not_student,ou=n,o=emu" ) { if ( "%{ldap:Ldap-Group}" == "cn=not_student,ou=n,o=emu" ) { Jason

Multiple BaseDN's - How Do I Do This?
by Rob VanDusen 12 May '08

12 May '08

I'm very new to both Linux and FreeRadius, so please excuse me if this is too easy a question. After a couple weeks of fighting, reading, testing and reconfiguring - I finally managed to get FreeRadius 2.x working with my Novell eDirectory. Right now my eDir tree is made up of 6 "O's" - one for each building in the organization. It looks something like this: ISDTREE | CTC | ESB | MTC | SPS | OAC | JSC My current config will check via LDAP against a NetWare box and authorize anyone in the ESB container - but I can't get it to look at any of the other containers. I tried doing multiple instances of the LDAP module - but that resulted in the server not authorizing anyone. How would I set this up so I can add the other O's as Base DN's? I'd really appreciate any instructions that a slightly dim bulb could follow. -Rob
