returning Vendor specific attributes to aruba
by Phil Brown 14 Jul '11

14 Jul '11

We are trying to use vendor specific attributes to provide different services to users authenticating to our local radius system, rather than users authenticating via proxy'd eduraom systems. we are using freeradius version 2.1.10 and have added the below to the users file DEFAULT Suffix == "@port.ac.uk" Aruba-User-Role = ROLE-EDUROAM-INT, Aruba-User-Vlan = 128, Class = ROLE-EDUROAM-INT, Fall-Through = Yes As far as I can tell, from the reply-detail log below & wirehark, Radius is returning the values. But the support guy is not seeing them on his wireless server. The first packets he sees are the MS-MPPE- packets. Can anyone advise as to to get this working. Packet-Type = Access-Accept Aruba-User-Role = "ROLE-EDUROAM-INT" Aruba-User-Vlan = 128 Class = 0x524f4c452d454455524f414d2d494e54 MS-MPPE-Encryption-Policy = 0x00000001 MS-MPPE-Encryption-Types = 0x00000006 MS-MPPE-Send-Key = 0xd1b37a684ca34b56aac068907f687067 MS-MPPE-Recv-Key = 0x0bb8b13849577453ba36e4de9dd7aafc EAP-Message = 0x030c0004 Message-Authenticator = 0x00000000000000000000000000000000 User-Name = "knighta" Thu Jul 14 10:30:31 2011 Packet-Type = Access-Accept MS-MPPE-Recv-Key = 0xf83b0cc1823377adaf6a4439054fd198eb9fb762b47dd4eaea5c8a90383af353 MS-MPPE-Send-Key = 0x98085e780f78ef5837581667c796ddbf3d8c317cdcd1c7b4b5b9742091b84253 EAP-MSK = 0xf83b0cc1823377adaf6a4439054fd198eb9fb762b47dd4eaea5c8a90383af35398085e780f78ef5837581667c796ddbf3d8c317cdcd1c7b4b5b9742091b84253 EAP-EMSK = 0x4268b7d02ec96bd566a0bb48ae21733f55f1da5ec296f959c84a83bd67a2cc45ce19f0c69924b9e9ed034f74eac19c8d904efbd4279b31499df4366ab6bbcf11 EAP-Message = 0x030d0004 Message-Authenticator = 0x00000000000000000000000000000000 User-Name = "monkey"

How to setup Freeradius
by Gilmour, Scott 14 Jul '11

14 Jul '11

I have been able to install freeradius using the Synaptic Package Manager. I installed these two packages openssl and the freeradius. I have also installed certificates. I have been able to get everything to work with freeradius except PEAP and TLS. Do I need to install other packages or do anything else in order to get PEAP and TLS to work? Thanks Scott

User Problem with Cisco Nexus 4.x
by Jan.Gnepper＠t-systems.com 13 Jul '11

13 Jul '11

Hi, I have a little problem. I have two devices within the same huntgroup, but i get in trouble with one of them. Both are Cisco Nexus, but there is one difference: The working one has NXOS 5.x, the one that is not working as expected NXOS 4.x Why is the right line in the users file found for the working device (line 67), but not found for the other device (line 136)? While both devices are in the same huntgroup and both requests look identically? Any ideas? Am i just blind? The interesting part is, that both requests look identical (even in tcpdump!). But the answer paket always shows a "bad udp checksum" when i´m not able to log in. 17:33:57.201238 IP (tos 0x0, ttl 64, id 1280, offset 0, flags [none], proto: UDP (17), length: 48) radius-server.datametrics > 10.48.137.62 .40077: [bad udp cksum 2dde!] RADIUS, length: 20 Access Reject (3), id: 0x17, Authenticator: 436530c99d29615e3a35aa878275a97d Is it possible that this causes my problem?

PAP authentication to Active Directory
by Axford M.F. 13 Jul '11

13 Jul '11

Hi I'm currently setting up a radius server to authenticate EAP based requests against Active Directory. Using Alan Dekok's guide I've got this authenticating mschap based EAP requests successfully. I also want to authenticate ttls/pap requests and I've found two ways to do this that seem to work. Method 1 is based on whats in http://freeradius.1045715.n5.nabble.com/EAP-TTLS-w-PAP-using-ntlm-auth-td27… Method 2 is to use LDAP for pap authentications. All things being equal my preference is to use Method 1 as it keeps all authentications the same, however the: if (!control:Auth-Type) { update control { Auth-Type = ntlm_auth_pap } } In the inner-tunnel/authorize section seems a bit like a hack. Is there a better way to do this ? Is either method particularly better than the other ?

Dear Community, I want to use SQL to send different Attributes of the same groupname based on NAS-IP-Address. for example 1024DL_512UL is the name of my group in sql. I want to send different Attributes based on NAS IP 2.2.2.2 and Different attributes for same group when NAS IP is 6.6.6.6 Any pointers. Thanks Waqas.

NAS re-uses the same port and ID
by Konstantin Chekushin 13 Jul '11

13 Jul '11

Hi all! I've found, that our NAS-server sometimes (when it restarts and there are many auth. packets comes to the radius-server) re-uses port and ID in a < 1 second period. (information from tcpdump) That causes " conflicting packet from client". I think, that the NAS works wrong (it must wait a little bit more, then 1 sec. to re-use the port+ID), that's why I wont to find some documentation about it for a bug-report. Thanks a lot.

Re: Wiki - Once upon a time there was documentation
by Nonny Mouse 12 Jul '11

12 Jul '11

I can confirm that some Wiki pages are blank (waiting to be edited). I checked, and they don't appear to be on the to-do list for conversion. Instead, it brings it up as a "Create New Page" dialog. I'm willing to help out with them, but need to create an account and review the stylesheets/directives for Restructured Text/Markdown first. Also, unlike other mailing lists I've used, I can't seem to figure out how to use the web interface to reply within an existing thread (I'm a new user, so I can't respond to the original mail or digest). We are planning to deploy FreeRadius within the next month, so I'm doing my homework first.

Local User with multiple passwords (or RegEX passwords) possible?
by Equin Nix 12 Jul '11

12 Jul '11

Hi, I am trying to set up something very basic (at least from my point of view): I would like to have a User with multiple passwords (two actually). How would I do this? I tried the following: *alice Auth-Type=Local, Cleartext-Password := "test1" alice Auth-Type=Local, Cleartext-Password := "test2"* which (of course) did not work. Then *alice Auth-Type=Local, Cleartext-Password := "test1" Fall-Through = Yes alice Auth-Type=Local, Cleartext-Password := "test2"* which (of course) did not work, too. Then I tried some regex, from which, the following do not work: *alice Auth-Type=Local, User-Password =~ "[*]*" alice Auth-Type=Local, User-Password =~ /*/i alice Auth-Type=Local, User-Password =~ "(test1)**" alice Auth-Type=Local, User-Password =~ "[.....]*" ...* How would I make an entry to users to have *alice *log in with "*test1*" OR "*test2*" as password? Best regards

Hi, I am using EAP-TTLS and MSCHAPv2 to authenticate with FreeRadius server.How can I get the tunnelled User-Name (User-Name used in inner authentication phase) using unlang in FreeRADIUS server? Now I can only get the User-Name used for the outer authentication (ex: anonymous). Best Regards Champika
