Radrelay
by lreeves 17 Dec '08

I found FreeRadius 2.1.1 very easy to setup for authentication however, I am experiencing problems in setting up the accounting with 2 servers. Radrelay was very simple and although I have found lots of information on the radrelay function built in to FreeRadius, I have not been able to get it working. Is there a shortcut, Howto or instructions on what files need to be changed to get the detail files to match on 2 servers? Thanks Larry Reeves lreeves(a)heartoftn.net

Working config file for data counter.
by Marcel Grandemange 16 Dec '08

Good Day. I am still struggling to get a working solution with freeradius and mysql as backend. What im trying to do simply is have the radius server use data counters instead of time counters. I want to limit a users collective data to amounts of 1gb,2gb,3gb, all the way up. And it must be resset on the first of the month. I have tried many versions of freeradius with many different queries and methods and there is ALWAYS something that doesn't seem to work properly. With Freeradius 2.1.3 I cannot use anything above 4gb, although I followed instructions on wiki to the tee for overcoming the wrapping problem. (wiki was outdated, but still tried) With 1.1.7 I think it was I would simply get arratic responses. Sometimes worked fine with up to 8gb tested, the next month it wouldn't. 2gb limits would also only sometimes work. The only one that was consistant was the 1gb option. Now ive tried so many methods, versions , tricks and wiki's and docs.. It's been years and still I cannot get it working correctly. There is a bit of a lack of docs on what I would like to do and ive come to the conclusion that if I could see someone elses working config for this sort of setup I could deduce where im going wrong. Thank You!

Re: FreeRADIUS vs Aradial RADIUS
by Aldo Zavala 16 Dec '08

Thanks for the input Alan, definitely I am sure FreeRADIUS is much better...what can be better than thousand of users, open source, free, and feature rich as itself... I apologize to all for the Subject of my inquiry, I wanted somebody to have tested Aradial and FreeRADIUS and tell me how professional can be this "Aradial". I am like scared because I am about to deploy a RADIUS AAA server in my network, and I was looking into commercial options... such as: Huawei: $500,000 DLLS (yes... DAMN!) Juniper: $100,000 DLLS ( !!! )... and here is FreeRADIUS... but I have no idea how to configure it... it like scares me because there are no manual to tell me step by step how to configure it to fit my needs and to feet my equipment.... I am in a cellular network (CDMA2000), I need to create two domains in AAA, one for EVDO and other internet services, the other for MMSC services, In order to have the capability of adding different subscribers in AAA under different domains, that way we can bill MMS and EVDO as separate services. I downloaded the FreeRADIUS mysql port in one FreeBSD box, I have no idea how to start configuring it there are many .conf files, and each config file is huge..., you told me in another reply that I have to configure FreeRADIUS to respond with the correct attributes that are needed by the PDSN, how can I know that? The Huawei PDSN documentation I have only tells how to configure the NAS with the "Huawei AAA" and dont say much about attributes.... can please tell what you mean with "attributes that are needed by PDSN?" what are those attributes and what they does? This is the relevant part of the PDSN config that I think is related to RADIUS: [conf] # interface Piif3/0/0 ip address 192.168.1.2 255.255.255.255 # interface Rpif3/0/0 ip address 192.168.1.1 255.255.255.255 # a11 enable pcf 192.168.0.200 192.168.1.1 256 skey 1234567891234567 # construct domain huawei domain enable domain AAAclientsig 1 domain address-group huawei 0 0 10.0.0.51 50 domain dns huawei 0 209.145.204.26 bip 209.145.204.20 # charge enable weekday 6 1 weekday 5 0 weekday 4 0 weekday 3 0 weekday 2 0 weekday 1 0 weekday 0 1 # [/conf] Thanks, Aldo Zavala Mobile (760) 556-5050 GTalk: aldo.zavala(a)gmail.com ----- Original Message ----- From: freeradius-users-request(a)lists.freeradius.org To: freeradius-users(a)lists.freeradius.org Sent: Mon, 15 Dec 2008 13:08:36 -0700 Subject: Freeradius-Users Digest, Vol 44, Issue 82 > Send Freeradius-Users mailing list submissions to > freeradius-users(a)lists.freeradius.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.freeradius.org/mailman/listinfo/freeradius-users > or, via email, send a message with subject or body 'help' to > freeradius-users-request(a)lists.freeradius.org > > You can reach the person managing the list at > freeradius-users-owner(a)lists.freeradius.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Freeradius-Users digest..." > > > Today's Topics: > > 1.

RE: Duplicate IPs for Radius Clients with different secrets

Yes I read about this, and I'll be upgrading soon and moving to Linux. When writing the DB lookups, can I use the User-Name attribute pulled from the requests? This will I think let me search for shared secret based on both the RadiusClient IP and the domain....the other server I tried couldn't do this. I would also consider using the MAC address of the AP instead or in addition to the domain. Thanks!

Problem returning default reply "Filter-ID" for Enterasys gear
by Kent Nasveschuk 16 Dec '08

16 Dec '08

Hello, I'm trying to set up MAC and 802.1x authentication and have a couple of questions. For right now I'm just working on the MAC authentication. Here's some info on my system: CentOS 5.2 [root@radius01 freeradius-1.1.3]# radiusd -v radiusd: FreeRADIUS Version 1.1.3, for host x86_64-redhat-linux-gnu, built on May 10 2007 at 12:24:01 Connecting on backend to OpenLDAP 2.3.39. Although in the production environment I will be running a replica on the radius server for testing I'm using a test LDAP server that I can modify at will.

Currently I can get a MAC address to authenticate and reply with the the correct "radiusFilterID" in LDAP. I can also get an unknown MAC address to return an ACCEPT but I can't get it to return a default "Filter-ID". Putting the return string "Filter-Id := "Enterasys:version=1:policy=D-Unregistered" in the users file doesn't seem to work. I'll work on the 802.1x when I get the above working, but I want to use the sambaLMpassword or sambaNTpassword hashes that are already in the LDAP directory versus clear text userPassword for 802.1x.

How does a RADIUS server work over the Internet? I'm not connecting the radius clients onto the same LAN. If a radius request comes in from the internet, would the server send responses to the Internet IP that it received it from (which I think would work for my case) or would it send to the radius client IP? Here's what I'm trying to do: Host a radius server on the Internet...for PEAP 802.1X (WPA-enterprise). Each AP at the different offices would be set with the Internet IP address of where the radius server is running, along with a shared secret. There would likely be APs set to the same IP address, that's why I'm asking about all this. > > Hi, I'm wondering if someone can point me in the right direction.

I know it traditionally doesn't, just checking to see what people think and if I might find a way to do what I want to do. What got me thinking something like this could work is when using a different server, I thought I could modify the SQL select statement that's used to find the shared secret. For example, the default is "select SharedSecret from NASES where ClientIPAddress='$c'" I thought I could just add the following to the end "and where Domain=(function that takes the domain from the username...after the @) I found that server can't register the username attribute during the select statement...so it all didn't work. Opps. I'm using v1.1.7 because at the moment I'm using FreeRadius.net on Windows Thanks for your help guys - Eric

Duplicate IPs for Radius Clients with different secrets
by Eric Geier 15 Dec '08

15 Dec '08

Hi, I'm wondering if someone can point me in the right direction. I want to list radius clients with the same IPs (and different shared secrets). This would let me use freeradius among multiple offices, where each could use the same IP addresses for the radius clients. I need something very dynamic; manually creating virtual servers in the config file won't work well. Right now I'm using v1.188.2.4.2.14 Thanks! Eric
