ippool with non-contiguous ip ranges
by Marco C. Coelho 27 Jul '08

27 Jul '08

I've got 3 class C ranges that are contiguous assigned to a freeradius server. I want to add an additional class C ranges to this server, but they are not contiguous with the previous three. I would like to add 64.202.231.1 - 64.202.234.254 without creating an additional IP Pool . I've searched the docs and net and cannot find an answer. my radiusd.conf has a section like this: SNIP*** ippool main_pool { # range-start,range-stop: The start and end ip # addresses for the ip pool range-start = 64.202.227.1 range-stop = 64.202.229.254 # netmask: The network mask used for the ip's netmask = 255.255.255.0 # cache-size: The gdbm cache size for the db # files. Should be equal to the number of ip's # available in the ip pool cache-size = 768 SNIP*** Thanks, Marco

hmm... it's true i didn't test authentication with another laptop! i will! and i will too with secureW2 instead ofXP built-in wireless manager, and see!! > see the logf there: http://tinypaste.com/5b99b Your problem is nothing to do with certificates. The PEAP tunnel gets setup correctly, the MS-CHAP client->server auth succeeds, but the final server->client (mutual) auth appears to fail. This could be for a number of reasons, but it's a problem at the client side. You will need to debug it at the client side. - List info/subscribe/unsubscribe?

definitively, I have a problem with eap-tls
by Sergio 25 Jul '08

HI, continuing with Reveal MAP problem with unknown ca's under eap-tls using default configuration.... private_key_file = ${certdir}/server.pem certificate_file = ${certdir}/server.pem CA_file = ${cadir}/ca.pem freeradius tell me this: rlm_eap_tls: <<< TLS 1.0 Handshake [length 0bdb], Certificate --> verify error:num=24:invalid CA certificate rlm_eap_tls: >>> TLS 1.0 Alert [length 0002], fatal unknown_ca TLS Alert write:fatal:unknown CA well, it isn't a problem: cp server.pem root.pem cat ca.pem >> root.pem then I change CA_file = ${cadir}/root.pem ......and.....eureka!!!! authentication succesfully ....but now there is a problem to check the CRL because root.pem then, something is wrong before making root.pem. ....well, just tell freeradius how to find certificates.... c_rehash /usr/local/etc/raddb/certs also doesn't works I think Reveal had the same problem and I have read about this on mailing list but nothing. Also I've tried to install ca.pem on /etc/ssl/certs using "ln -s". Has somebody encountered problems with this apart from Reveal MAP and me? P.D. route certification into windows isn't a problem, only tell xp_supplicant who is root authority (It was logical)

New SNMP Code
by Alan DeKok 25 Jul '08

25 Jul '08

Sky Network Services has contributed a preliminary implementation of SNMP in the server. It's a Perl script that communicated with net-snmpd via the AgentX protocol. and with FreeRADIUS via the new Status-Server statistics functionality. The result is that you can now obtain FreeRADIUS statistics via SNMP. The code is alpha, but has been tested to work. Please test, and submit patches, suggestions, fixes, etc. back to the list, or to bugs.freeradius.org. See http://git.freeradius.org for the latest source. The new SNMP is in scripts/snmp-proxy/ Alan DeKok.

PEAP or TTLS and Microsoft Vista.
by Lech Karol Pawłaszek 24 Jul '08

24 Jul '08

Hello. I need your help. For the last few days I try to authenticate and authorize Microsoft Vista operating system against FreeRADIUS and 3com switch (as NAS) for wired authentication with no luck. I'm using FreeRADIUS 2.0.5 from sources built on Debian Etch GNU/Linux and certs made by bootstrap command (so those certs should have a bit of magic from xpextensions afaik). I try to make little steps and change as less as possible - to be honest I've only added user to the users file and client definition to the clients.conf file. I've tested my configuration with eapol_test command (as suggested at this site[1]) and it works fine. I've tested it against MacOsX 10.4 and MacOsX 10.5 and it works fine. I even tested it against Windows XP SP2 and it works fine. It doesn't work with Windows Vista and Windows XP SP3. Please help! What I have spotted is that the server sends "Access Challenge" and then on OSX dialog pops up where I can accept server's certificate and on Windows it's over. So I think it's the issue mentioned on this site[2] however i DO have Validate Server Certificate un-checked. One more thing. If I won't use Windows' PEAP authorization and install securew2 and use securew2's auth - I am able to connect. Work for a minute or so and then NAS reports lost carrier and the connection is lost. I've written about this issue about a year ago however this was put on-hold. You might want to look at logfiles from that tests. [1] - http://deployingradius.com/scripts/eapol_test/ [2] - http://deployingradius.com/documents/configuration/eap-problems.html [3] - http://lists.freeradius.org/pipermail/freeradius-users/2007-July/msg00096.h… Any hints and tips much appreciated. I'm attaching two logfiles. The first one - freeradius.log - is the one where I'm trying to authenticate using system-wide PEAP. The second one, namely freeradius-securew2.log, is the one where switch receives Access-Accept and a few moments later switch sends back information that the carrier is lost. I've compressed both logfiles. I hope it's ok here. If it's not - please let me know. Thanks in advance. -- Lech Karol Pawłaszek <ike> "You will never see me fall from grace." [KoRn]
