Alan, changing from User-Password to Password-With-Header brought back the 'No "known good" password' error. I'm going through the rlm_pap.c code to try to see what's going on here. I haven't found any docs yet on what the various mapping possibilities are and what they do. Do you have a pointer to any so I don't keep bugging you and the list? I agree with the 'get it work, then tune it' approach. That's where I'm at now. It's working, I'm just trying to make all the messages go away :) Thanks! Tom Here is a snippet from radiusd -X: [ldap-server1] Added Crypt-Password = 4gOgBZqZgtwIw in check items [ldap-server1] looking for check items in directory...

Solaris 10 1.13 FreeRadius
by Kory Wheatley 29 Jul '10

29 Jul '10

Will LDAP failover work on Solaris 10 with FreeRadius 1.1.3 ? This is the default that comes with Solaris or do we need to upgrade FreeRadius.

coa proxy'ing with a NAC device
by Kevin Ehlers 29 Jul '10

29 Jul '10

I'm having a really hard time with proxying or just dealing with CoA's. The documentation just isn't working for me. I can configure the coa server. I can get the originate-coa server up too. I can send CoA's to the server, but I can't get it to proxy them or re-send them as if it was originating the CoA. I see that they're being processed when looking at debug mode. But I just don't know how to do anything with them. This is what I want to do: [lots of switches doing dot1x]<->[freeradius]<->[NAC device, PacketFence in this case] I want to be able to send a CoA request from PacketFence (or another management server) to freeradius, and have it relay that CoA to a specific switch. E.g. I have determined that a user needs to be quarantined, so I run a script on the backend, and part of that requires having that user re-authenticate and get assigned a quarantine vlan. PF determines which switch they're on, sends a CoA to FreeRadius, FreeRadius then sends the CoA to the correct switch. Is there a way to do this without configuring a client entry for every edge device? Should I be using the proxy.conf in some way? I'm not really clear about how to use the virtual servers in regard to proxying. Thanks, -- Kevin Ehlers Network Engineer University of Oregon

send radius response without request
by Sallee, Stephen (Jake) 29 Jul '10

29 Jul '10

Is it possible to have FreeRADIUS send a radius response without first receiving a request, provided I can feed it the same information the request would have? OR Is it possible for FreeRADIUS to see the request come from one host and have the response go to another? Jake Sallee Godfather Of Bandwidth Network Engineer Fone: 254-295-4658 Phax: 254-295-4221

Error: ASSERT FAILED threads.c[406]
by Meyers, Dan 28 Jul '10

28 Jul '10

Quick bit of background. We're using FreeRADIUS in combination with rlm_perl for network access control at our site. Everything was running fine on FreeBSD 8.0 with FreeRADIUS 2.1.8 compiled from ports and Perl 5.8 compiled to be non-threaded and not support multiplicity. We got new higher spec servers from Dell, and sadly the only *nix OS that currently supports the RAID card in them seems to be Ubuntu Server 10.4, so we're now on that. Perl is compiled (as it is by default on Ubuntu) with threads and multiplicity, but some testing by hammering the server from multiple different machines using radclient and some test packets from a file seemed to show that (unlike the last time we tried, which I believe was on FreeRADIUS 2.1.3) using threaded perl was stable and worked fine with rlm_perl in FreeRADIUS (it used to lock up eventually). Ran fine for a week or so, but in the last few days we've had it crash twice, both times with the same message. The logs initially fill with messages of the sort: "Sat Jul 24 01:05:08 2010 : Error: WARNING: Unresponsive child for request 128145, in module perl component accounting" and "Sat Jul 24 01:05:08 2010 : Info: WARNING: Child is hung for request 128145." We'll end up with 32 of the former type of error message (we're currently running with 32 threads configured in the thread_pool in radius.conf), interspersed with the latter, then a stack of the latter type of error (Always for the same set of requests, i.e. one of the ones we got an initial error for, but we'll get the second error multiple times for a given request). Then eventually we get "Sat Jul 24 01:05:27 2010 : Error: ASSERT FAILED threads.c[406]: (*request)->magic == REQUEST_MAGIC" All our accounting module does in perl is convert the incoming radius hash to yaml and then attempt to write it to a database with a timestamp. I am strongly suspecting that the initial problem is to do with threading in combination with the DBD::MySQL module in perl or the MySQL client rather than FreeRADIUS, despite our testing seeming to show it was OK. But I do not think that final ASSERT FAILED error should be being generated as a result of the former issue. I am trying to understand what is going on. Is FreeRADIUS attempting to kill the deadlocked threads and being unable to do so? Thanks Dan

incorrect auth-type
by Sallee, Stephen (Jake) 28 Jul '10

28 Jul '10

I am new to FreeRADIUS so please be patient with me. I am scouring the docs as I write this but so far I have been stumped. Below I have included the debug output of my server when I send it a authentication request.
