Two different sets of Group Authentication
by Raheel Itrat 26 May '11

26 May '11

Hi, Currently I am authenticating only One group of users in Cisco Switches group. Now, I have to add another VPN group and distinguish between two sets of group autentication , VPN Users, and Cisco switches. I'd like to control access to each of those separately (different AD Groups SIDs). Do i have to do somethinbg like creating two modules (ntlm_auth and ntlm_auth2) or two different mschap modules with respective ntlm_auth entries? Even then how would it differentiate between the two? Is defining huntgroups an option if using ntlm as Auth type? BR, Raheel

How to test raduis is working.. can't find radtest
by Luke Hammond 25 May '11

25 May '11

I have just installed FreeRADIUS 2.07 i think it is.. anyways. i followed a tutorial on how to install in with MySQL on Centos 5 and when i get to the part about testing the database using radtest.. it doesnt work. radtest is not where it should be, have looked on google to try and work out where esactly this 'radtest' lives, but all the locations it i supposed to be.. it isnt! So, where should it be and why isnt it there? do i have to install it separately? Also, how do i test that my radius is working and accepting logins without it?

Who processes VLAN information?
by Alexandros Gougousoudis 25 May '11

25 May '11

Hi, if I'am transmitting VLAN Information back to the supplicant, after an Acces-Accept (see below), who does this information use? Is it an information for the Switch, working an an Authenticator, to put the switchport into VLAN 22 or is it for the Supplicant/Client to enable VLAN tagging and send all packets with the VLAN 22 tag? Who is honouring these information? radtest -t mschap host/scit-beerchen test 127.0.0.1:1812 0 testing123 Sending Access-Request of id 16 to 127.0.0.1 port 1812 User-Name = "host/scit-beerchen" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 MS-CHAP-Challenge = 0x315c8360df930d89 MS-CHAP-Response = 0x0001000000000000000000000000000000000000000000000000ebec6d1eb202859db7dcc8586ecc2469b8dae48d7aabb3ab rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=16, length=100 Tunnel-Private-Group-Id:0 = "22" Tunnel-Medium-Type:0 = IEEE-802 Tunnel-Type:0 = VLAN MS-CHAP-MPPE-Keys = 0x00000000000000002066656e05c22f3a995ad9ecfed913d60000000000000000 MS-MPPE-Encryption-Policy = 0x00000001 MS-MPPE-Encryption-Types = 0x00000006 TIA Alex

Hello, I need your help with freeradius proxy configuration. What I would like to do is to configure freeradius as a proxy to forward all the authentication requests to another radius server without having to wait for an answer from the RADIUS server.

RSA Freeradius Proxy Client IP address
by Locnar 25 May '11

25 May '11

I have an RSA Securid server that is being proxied by FreeRadius. Everything works great. When a client on a remote device authenticates, they are authenticating against the FreeRadius server's address. So I assume FreeRadius is the NAS. How do I force the client device's IP to be the one authenticated, not the FreeRadius server? I think I've tried about every attribute I can think of. And read the RFC's too! -- View this message in context: http://freeradius.1045715.n5.nabble.com/RSA-Freeradius-Proxy-Client-IP-addr… Sent from the FreeRadius - User mailing list archive at Nabble.com.

Sleeping until we see a request. As you can see the CallingStationId is empty, also there is no mention of it in the Accounting request packet. If this is not supported by the accounting, is there a way to get it from the authentication section? Would also like to say that I know this is more related to the PAM module and I assume this makes this mail a bit out of context in this mail group, but any help would be most appreciated.

Sending Reply-Message in Access-Reject (PEAP/MSCHAPv2)
by Martin Goldstone 24 May '11

24 May '11

Hello, Just looking for a bit of advice here. I've been setting up freeradius here recently, and whilst I'm mostly finished, there are a few points that still need to be addressed. The main one is sending a (semi) meaningful reply message when a user is rejected. Unfortunately, I'm having trouble figuring out how to return a Reply-Message from with in the inner tunnel. Well, to be more specific, returning that Reply-Message within the final Access-Reject. So far, I've figured that I can update outer.reply within the inner tunnel, but this gets sent out in an Access-Challenge follows the initial failure, but not subsequently. I've tried to put the update clause within Post-Auth-Type REJECT {}, both in the inner tunnel and outside as well, with no sucess (the inner one appears never to be called), the outer one has no knowledge of what was set in the inner one, so I could set an arbitrary message such as "failed", but I was hoping to be a little more helpful than that. Any pointers as to where to look/what to do, or even if this is possible, would be appreciated. Thanks in advance, Martin -- Martin Goldstone Keele University, Keele, IT Systems Administrator Staffordshire, United Kingdom, ST5 5BG Finance & IT Telephone: +44 1782 734457

HOWTO add Framed-Ip-Address AVP to Access-Request while proxying
by Nitin Bhardwaj 24 May '11

24 May '11

Hi, I am using FreeRADIUS to proxy EAP-PEAP authentication as MSCHAPv2 to a third-party RADIUS Server. (Terminating the outer tunnel at FreeRADIUS). However, I need to send an AVP of "Framed-Ip-Address" to the third party RADIUS server ( its a legacy server), for which I tried adding a realm entry into attrs.pre-proxy: -----------------------------------------------< SNIP >------------------------------------------------------------- #brokenas # NAS-Port-Type == Ethernet # Fall-Through = Yes # The rest of this file contains the DEFAULT entry. # DEFAULT matches with all realm names. MyRealm.com Framed-IP-Address := 192.168.50.12 Fall-Through = Yes DEFAULT User-Name =* ANY, User-Password =* ANY, CHAP-Password =* ANY, CHAP-Challenge =* ANY, MS-CHAP-Challenge =* ANY, MS-CHAP-Response =* ANY, EAP-Message =* ANY, Message-Authenticator =* ANY, State =* ANY, NAS-IP-Address =* ANY, NAS-Identifier =* ANY, Proxy-State =* ANY -----------------------------------------------< END >------------------------------------------------------------- But FreeRADIUS is not generating the "Framed-Ip-Address" in the outgoing Access-Request (MSCHAPv2). How can I make FR generate the AVP ?/ /Nitin
