Using unlang / SQL with single return value; couple of questions.
by Dom Latter 27 Apr '18

27 Apr '18

(This is partly a continuation of the thread "Perl vs. python vs. Lua?" started late February) [1]. First thanks to Alan for pointing me in the right direction. I thought I would describe the process for the benefit of others. Basically we need to assign wifi users a VLAN based on their location and username. If they are rejected we want to put a reason in the Reply-Message (and this *should* in due course end up in the line log and the postauth table). We have been using a PHP script. To replace it I have put the bulk of the logic in to the SELECT clause of the SQL query. If there's a "normal" VLAN available it's in the range 1 to 4096. Return codes 5000 to 5005 indicate "accepted" but with special conditions. Return codes 5010 to 5014 indicate "reject". Return codes above 10000 indicate a VLAN applied a different way, and so on. So in in our default server in the post-auth block we have (for example): update control { CustomVal := "%{sql:SELECT \ CASE \ WHEN (cs_suspended.value = '1') THEN 5010 \ WHEN (u.deleted != '0') THEN 5011 \ // etc Then the unlang code "decodes" the return value: if ( &control:XL-Vlan < 5000 ) { update reply { Filter-Id := &control:CustomVal Reply-Message += "Accept: MAC found." } } elsif (.... So I have managed quite okay without the map functionality of version 4; in fact, as the query should cache quite nicely it's possible that it's much better to put as much logic as possible into the query... I hope the above is reasonably clear - I have done my best with the time available! 1st question: I am currently using a REGEXP in the query to perform a partial match and would prefer to use a LIKE '%foo%' instead... but the % wildcard seems to conflict with freeradius's own substitution. Anybody know a workaround? 2nd question: we use a "magic" MAC address for non-wifi authentication; which contains for no good reason, an exclamation mark. The problem is that in the query the '%{request:Calling-Station-Id} gets expanded such that the '!' becomes '=21'. So my WHEN clause in the SELECT has to match on '=21'. Any workarounds so that the SQL query would see the "real" value? [1] I only do this gig part-time and only part of *that* is spent on freeradius development,

Are config and control list equal?
by work vlpl 26 Apr '18

26 Apr '18

Hello, The documentation/wiki for rlm_python module https://wiki.freeradius.org/modules/Rlm_python says, that module can return tuple of 3 elements (return code, reply attributes, config attributes) For debug purposes I added additional instructions in raddb/polici.d/debug debug_config { if("%{debug_attr:config:}" == '') { noop } } And noticed in debug output this (6) policy debug_config { (6) if ("%{debug_attr:config:}" == '') { (6) Attributes matching "config:" (6) &control:Auth-Type = MS-CHAP (6) &control:Cleartext-Password = testing (6) EXPAND %{debug_attr:config:} (6) --> (6) if ("%{debug_attr:config:}" == '') -> TRUE (6) if ("%{debug_attr:config:}" == '') { (6) [noop] = noop (6) } # if ("%{debug_attr:config:}" == '') = noop (6) } # policy debug_config = noop and debug_control policy return the same results (6) policy debug_control { (6) if ("%{debug_attr:control:}" == '') { (6) Attributes matching "control:" (6) &control:Auth-Type = MS-CHAP (6) &control:Cleartext-Password = testing (6) EXPAND %{debug_attr:control:} (6) --> (6) if ("%{debug_attr:control:}" == '') -> TRUE (6) if ("%{debug_attr:control:}" == '') { (6) [noop] = noop (6) } # if ("%{debug_attr:control:}" == '') = noop (6) } # policy debug_control = noop Is this means what control and config lists are equal?

Issue with EAP authentication on packet loss
by jm+freeradiususer＠roth.lu 26 Apr '18

26 Apr '18

Hello, We have a problem when packet loss occurs at step #4 of the EAP dialogue: 1) Access-Request 2) Access-Challenge 3) Access-Request 4) Accept or Reject (in this case: Access-Accept) 5) Access-Request (duplicate) 6) Reject In this case, #4 is sent by the server but gets lost on its way to the NAS. I've managed to reproduce using iptables dropping the packet. So after some time the NAS sends packet #3 again. At that point I am getting "No EAP session matching state" from the eap module in the "authenticate" section and the request is rejected. This is consistent with what we see in step #4 (upon sending the Access-Accept which gets lost), namely this: (1) eap : Expiring EAP session with state 0x2f8521a02f84259c (1) eap : Finished EAP session with state 0x2f8521a02f84259c (1) eap : Previous EAP request found for state 0x2f8521a02f84259c, released from the list Who's at fault? How do you solve this (except for not using UDP)? Do you set aggressive timeouts/retries on the NAS? Thanks, Marki

What is the recommended way of overriding a mod file like "realm"
by Nick Howitt 26 Apr '18

26 Apr '18

The reason I am asking is because domain logins are appearing as "user/machine.domain". I can make it work by adding a realm in proxy.conf (or a parallel file and adding an INCLUDE in radius.conf): realm "~(.*\.)*domain$" { } But I also either have to change the delimiter in the "realm suffix" section of /etc/raddb/mods-available/realm from "@" to "/" which means the file is non non-standard or I have a couple of choices of adding a block: realm realmclearos { format = suffix delimiter = "/" } at the bottom /etc/raddb/mods-available/realm or in its own file in mods-available and symlinking to it from mods-enabled, but then, either way, I also have to add a line "realmclearos" in /etc/raddb/sites-available/default around the line saying "suffix" which makes /etc/raddb/sites-available/default non-standard. There is a fair push on the mailing lists of keeping things standard and I am wondering what is the best direction - or is my solution completely wrong. Thanks, Nick
