What does 'radius -C' do? (2.1.3)
by Mike Diggins 09 Mar '09

09 Mar '09

According to the documentation, radiusd -C is supposed to "Check configuration and exit." I was assuming that would catch errors in the configuration that might prevent it from restarting. However, if I intentionally mangle the configuration to the point it won't start, the -C check still returns nothing. What am I missing? -Mike

Ok! Where can I find information about howto make freeradius undarstand a TACACS+ ?

No. in my company we use a freeradius, not a TACACS, and we want to get a control under some users which work on cisco console and for this we would be like take a 'log command'. If you know how we make do that and freeradius implemet this, please tell us or give a some howto, patch, url etc. Still we implement unsuccessful.

Can we do sql just once during eap-tls handshake
by Johan F2 09 Mar '09

09 Mar '09

We are using eap-tls for authetication assisted with a database for filling in some attributes. FreeRADIUS Version 2.1.3 with minimal configuration will do a sql lookup for each round. (Four selects: radcheck, radusergroup, radgroupcheck and radgroupreply). There are 6-9 rounds depending on certificate chain sizes. Obviously performance would be better with only one database lookup. Part of the (attempted) configuration: authorize { preprocess eap if (I have tried some conditions here) { sql if (notfound) { fail } } } authenticate { eap } Is there som nice condition that will result in only one lookup in the database? A thing that complicates thing is that TLS (that declares Success I beleive) is run during authenticate which is later the the attempted database lookup. The TLS outcome is pretty well known in the second last round: There are logs saying [tls] (other): SSL negotiation finished successfully SSL Connection Established but there is still one Access-Challange. So if this fact could be tested in the last round that test would be a nice candidate for doing the sql update. As an aside: Is there a way to really inspect the client certificate (preferrably the entire chain) and let it affect some logic (in perl as an example)? -- View this message in context: http://www.nabble.com/Can-we-do-sql-just-once-during-eap-tls-handshake-tp22… Sent from the FreeRadius - User mailing list archive at Nabble.com.

radiusd server does not respond to radtest from another host
by mbhorner＠aol.com 09 Mar '09

09 Mar '09

[>Thanks for the response. My original email was very lengthy, but at the bottom you can see a wireshark capture showing the packet arrival. (My understanding is wireshark is a pretty GUI based on tcpdump) > Yes, it arrived but can't get through the firewall. You say you are using default freeradius configuration, so you haven't done anything strange to listen section to cause this - it has to be tha firewall.] OK, I'll investigate the firewall this morning - I am new to openSUSE so I don't know where that is but hopefully google will point me in the right direction. FYI - I uninstalled both installations, removed all the files under /etc/raddb and reinstalled only editing "users and clients.conf" What I found is on the 10.10.10.11 machine which has a full 32 bit version of openSUSE 11.1 installed that radiusd did not respond from other host. It did respond to radtest from another terminal window on the same machine I then started Linux using a openSUSE 64 bit "live CD" on my 10.10.10.10 machine (because its hard drive has windows). In installed the basic packages needed to get freeradius running (C/C++ dev, gnu make etc) - I used an identical "users and client.conf file" with 24 bit mask for clients in 10.10.10.0 On the liveCD host the freeradius server works! - so perhaps it is a lack of firewall? Note: I alsotraied changing the NAS-ID as suggested in another thread - that did not seem to make any difference 10.10.10.11 did not work with either NAS ID while 10.10.10.10 worked with either Thanks for the tips - I will cross my fingers it is a firewall setting that is installed by default in openSUSE 11.1
