statistics with radsniff and collectd
by Louis Munro 10 Nov '14

10 Nov '14

Hello, I am trying to integrate radsniff with collectd as described on the wiki : http://wiki.freeradius.org/guide/stats-with-radsniff#collectd I have compiled radsniff 3 statically (it is to be used on a 2.2.5 server) and it seems to be working fine as long as I don't try to write to the collectd socket. When I do however I get these errors back from collectd: radsniff: Failed PUTVAL "pf-auth1-ddc.net.utah.edu/radsniff-exchanged/radius_count-coa_nak" interval=10 1415655243 : Server error: Type `radius_count' isn't defined. radsniff: Failed PUTVAL "pf-auth1-ddc.net.utah.edu/radsniff-exchanged/radius_latency-coa_nak" interval=10 1415655243 : Server error: Type `radius_latency' isn't defined. radsniff: Failed PUTVAL "pf-auth1-ddc.net.utah.edu/radsniff-exchanged/radius_rtx-coa_nak" interval=10 1415655243 : Server error: Type `radius_rtx' isn't defined. So it looks like I need to define the types for the radius statistics in collectd's Types.db. Has anyone got this working? The question is rhetorical as I assume that the wiki's author (at least) got it to work but I don't seem to have the relevant definitions with my version of collectd (5.4.1). Would anyone care to share their type definitions? I would be much obliged.

FR 3.0.5 Expected Debug
by Patrick Gawthorne 10 Nov '14

10 Nov '14

Hi All, First time using FR 3, after configuring to authenticate with AD the debug that gets spat out appears quite long. I am just making sure this is normal, expected behaviour and if not what I have done wrong.. I've attached the radiusd -X output of one client (iPad) connecting. Config items should all be default except things like mods-available/mschap, mods-available/eap, as per http://wiki.freeradius.org/guide/FreeRADIUS-Active-Directory-Integration-HO… .. Thanks to anyone willing to help. :) Cheers, Pat This email, together with any attachments, is intended for the named recipient(s) only and may contain privileged and confidential information.

populate a reply with ldap generic attributes
by Nicolas Edel 10 Nov '14

10 Nov '14

Hi, Using LDAP for both autorization and authentification, I learnt how to populate a reply request with generics in the autorize. Works fine. Now I am wondering if it would be possible to populate the reply with generics using a dn specified in an ldap attribute. The goal of this is to have predefined profiles to specify user rights (such as read-only, operator, admin, etc) specified only once and to refer to them into the user profile. Since these are generic attributes (of type radiusAttribute), I can't see anyway to use xlat for this. I would be pleased if someone could provide me any hint. Thanks. :Nicolas

Dailycounter not working

unlang vs suffix
by Rui Ribeiro 07 Nov '14

07 Nov '14

Hi, I have a simple doubt; I have seen many times a couple of people saying they prefer to use unlang than the suffix directive; what´s the advantage of - supposing proxy.conf is adequately configured, instead of doing suffix do instead (ignore the if part, I know it is missing in the example above, it is here just for the sake of clarity): if (!(User-Name =~ /^([^@]*)@(.+)$/)) { update reply { Reply-Message := "malformed username" } reject } else { update request { Stripped-User-Name := "%{1}" Realm := "%{2}" } if (Realm == "iscte.pt") { update control { Proxy-To-Realm := LOCAL } } else { update control { Proxy-To-Realm := EDUROAM } } } Regards, Rui Regards, Rui Ribeiro

Multi-tenancy setup
by Ilavajuthy Palanisamy 06 Nov '14

06 Nov '14

Hi All, We are hosting an application in the cloud which is managing multiple customers. Customers will be authenticated using the FreeRadius server. We are planning to use the user authentication through the database(PostgreSQL). I have configured the radcheck table and able to make the user authentication successfully. In order to support multiple customers, what are all the options/design available in FreeRadius. One option we are thinking is to modify the schema to introduce customer-id and modify the sql module to support the new schema. If this is possible, please provide pointers in achieving this. If there are other options available, please provide pointers. Thanks, Ila.

Blank value of temporary variable in Unlang
by Mrinal K 06 Nov '14

06 Nov '14

I am implementing a setup where we return expiry date value as per a user's settings. For this I have added a column in radcheck table called ExpiryDate. I have added following in authorize section in sites-available/defaults update control{ My-Local-Int-1 := "%{sql: select id from radcheck where username='%{User-Name}' order by id desc limit 1}" } update reply{ WISPr-Session-Terminate-Time = "%{sql: select ExpiryDate from radcheck where id = '%{My-Local-Int-1}'}" } The username I am testing with has ExpiryDate value in radcheck table, however mysql query log shows me blank value for '%{My-Local-Int-1}' for query in update reply {.. } section. Please suggest what I am doing wrong. My-Local-Int-1 has been defined in dictionary as integer.

Multivalued attribute[*] comparisons
by Arran Cudbard-Bell 06 Nov '14

06 Nov '14

Master branch which will become 3.1 now supports multivalued conditions. If an attribute with the '*' index is used in a condition, all values of that attribute will be evaluated against the other operand. If one set of values evaluates to true, no further values are checked and the condition returns true. update request { Tmp-String-0 := 'foo' Tmp-String-0 += 'bar' Tmp-String-0 += 'baz' Tmp-String-1 := 'aaa' Tmp-String-1 += 'bbb' Tmp-String-1 += 'ccc' Tmp-String-1 += 'bar' } # # Yes this is O(N^2) - worse case here is 12 comparisons # if (&Tmp-String-0[*] == &Tmp-String-1[*]) -> TRUE if (&Tmp-String-1[*] =~ /cc$/) -> TRUE If used with capture groups, contents will be from the first value that matched. if (&Tmp-String-1 == 'bar') -> FALSE if (&Tmp-String-1[*] == 'bar') -> TRUE In theory this will allow update request { Admin-Groups := 'admins' Admin-Groups += 'net-admins' Admin-Groups += 'Administrators' } if (LDAP-Group == &Admin-Groups[*]) But I believe the parser's condition rules will currently prevent that (will be fixed before 3.1 is released). It also works for integers: update request { Tmp-Integer-0 := 5 Tmp-Integer-0 += 10 Tmp-Integer-0 += 15 } if (Tmp-Integer-0[*] > 15) -> FALSE if (Tmp-Integer-0[*] < 5) -> FALSE if (Tmp-Integer-0[*] < 10) -> TRUE The evaluation code also avoids many of the temporary mallocs that it previously did, as the cast and comparison functions have been updated to work with value data, as well as value pairs. The main use case for this feature is checking multiple group or authorizational attributes for a value. It also works with tag qualifiers. -Arran Arran Cudbard-Bell <a.cudbardb(a)freeradius.org> FreeRADIUS development team FD31 3077 42EC 7FCD 32FE 5EE2 56CF 27F9 30A8 CAA2
