update NAS-Identifier in Access-Request before proxying to other radius server
by C.F. Yeung 06 Jun '12

I want to update NAS-Identifier in Access-Request before proxying to other radius server. Tried adding the following lines in default but in vain. So, where should I put the following unlang? update request { NAS-Identifier = "new-nas-identifier" }

unable to authenticate with Crypt-Password
by abrooks 05 Jun '12

05 Jun '12

Hello I cannot get my freeradius server to authenticate using a users file which is used successfully on a couple of older servers. I'm trying to replace one of the old machines with a VM running on a ubuntu host using VirtualBox. I am running a ubuntu 10.04 64 bit virtual server with FreeRADIUS Version 2.1.8, for host x86_64-pc-linux-gnu, built on Jan 5 2010 at 02:56:18 installed using apt-get install. I use a users list to authenticate. My users file is commented out except for 3 lines: bob Cleartext-Password := "hello" $INCLUDE users.1003512 $INCLUDE users.1033872 -bob was added for testing users.1003512 and user1033827 are identically formatted. Here is a sample from users.1033872: abrooks1(a)iroam.uk Crypt-Password == "$1$BbFRsHhY$.Qcjjczle/i94ILxuajvT/" Auth-Type = Crypt-Local, User-Service-Type = Framed-User, Framed-Protocol = PPP, Framed-Address = 255.255.255.254, Framed-Netmask = 255.255.255.255, Framed-Routing = None, Framed-Compression = Van-Jacobsen-TCP-IP, Framed-MTU = 1500 abrooks2(a)iroam.uk Crypt-Password == "$1$mqZm0XU5$4ZGIcC.9AdoDvqdGQDpNo0" User-Service-Type = Framed-User, Framed-Protocol = PPP, Framed-Address = 255.255.255.254, Framed-Netmask = 255.255.255.255, Framed-Routing = None, Framed-Compression = Van-Jacobsen-TCP-IP, Framed-MTU = 1500 I use these same users files on two older, working Freeradius servers.

accounting in syslog
by Luo, Frank Y.F. Mr. 05 Jun '12

05 Jun '12

Is there a way to send accounting log to syslog instead of detail file in radacct? Also instead of sending it to sql db, i tried to use sql-file but it results in a lot of sql command (we really don't want to run the sql command later). INSERT INTO radacct (AcctSessionId, UserName, NASIPAddress, FramedIPAddress, AcctStartTime, AcctStopTime, AcctSessionTime, AcctTerminateCause) VALUES ('4fc645a8/00:25:00:3e:e6:c2/188601', 'luoy', '172.18.47.242', '172.25.128.186', '2012-05-30 12:07:04', '0', '0', ''); INSERT INTO radacct (AcctSessionId, UserName, NASIPAddress, FramedIPAddress, AcctStartTime, AcctStopTime, AcctSessionTime, AcctTerminateCause) VALUES ('4fc645d8/10:40:f3:1c:a3:b4/188604', '1040f31ca3b4', '172.18.47.242', '172.24.146.51', '2012-05-30 12:07:52', '0', '0', ' '); Also noticing the UserName part, a lot of times that a binary username is logged, like here "1040f31ca3b4", instead of the real name. How to fix this? THanks for the help Frank

Hi all, i'm configuring a user with class Attribute like this on freeradius: tom Cleartext-Password := "tom123" Service-Type = Login-User, Juniper-Local-User-Name := "readonly-users", when i launch freeradius -X, and i connect with tom from the router i see that the user logs Ok But freeradius don't send the vsa attribute????: I see this on the console: Sending Access-Accept of id 65 to 172.16.1.11 port 62458 Finished request 5. I see on the net and i normally see this: Sending Access-Accept of id 65 to 172.16.1.11 port 62458 Juniper-Local-User-Name = "readonly-users" Finished request 5. Do I have to change something on the configuration file to enable sending VSA Attribute?

How to configure Solaris 10 Radius Authentication client.
by Alek Barsky 04 Jun '12

04 Jun '12

Hi Guys, I need to configure bunch of Solaris servers to use RADIUS PAM for Authentication/Authorization. I followed instructions in http://freeradius.org/pam_radius_auth/ and was able to configure Authentication portion of this task. There is one problem - the only way I can receive login shell on this box - if user already exists. I suspect I need to pass some variables from RADIUS server to my Solaris RADIUS client. Does anybody know what are they? Thanks, Alek. This e-mail (and attachment(s)) is confidential, proprietary, may be subject to copyright and legal privilege and no related rights are waived.

Freeraduis as accounting proxy

Hello, I'm trying to set up my freeradius to be an accounting proxy. No it only receives acct packets and saves data in log files. The configuration is below: radiusd.conf: accounting { detail fail } detail { detailfile = ${radacctdir}/%{Client-IP-Address}/detail-%Y%m%d%H.log } client.conf: client 126.18.130.8 { secret = faultcenter shortname = fault-center } I added the following to the proxy.conf, but freeradius don't sends any accounting packets: realm LOCAL { type = radius authhost = 126.20.50.230:1812 accthost = 126.20.50.230:1813 secret = fault } realm NULL { type = radius authhost = 126.20.50.230:1812 accthost = 126.20.50.230:1813 secret = fault } realm DEFAULT { type = radius authhost = 126.20.50.230:1812 accthost = 126.20.50.230:1813 secret = fault } Can somebody help? -- View this message in context: http://freeradius.1045715.n5.nabble.com/Freeraduis-as-accounting-proxy-tp57… Sent from the FreeRadius - User mailing list archive at Nabble.com.

Proxy-State in a CoA proxied request
by fab junkmail 04 Jun '12

04 Jun '12

Hi All. I have tried filtering out Proxy-State attribute for proxied CoA in pre.proxy section but it does not seem to work for me. Debug mentions the following which makes me think it is not using the DEFAULT section of attrs.pre-proxy: [attr_filter.pre-proxy] expand: %{Realm} -> ++[attr_filter.pre-proxy] returns noop (more debug in context below) Have you got this filtering to work Frédéric? If so, can you show me relevant parts of your config that shows how to make it work? Does anyone have any advice on how I can fix my config to be able to filter out (or not add) Proxy-State attribute for proxied CoA? I have included relevant parts of my config and debug below.

Checkrad and Cisco WLC 4400 NAS
by Patrick Machauer 02 Jun '12

02 Jun '12

Hi, i've got a problem with simultaneous-use and a Cisco WLC4400. If i choose nastype=other in clients.conf the radaact table gets queried and if there is a running session for that user ( acctstoptime IS NULL) the user gets rejected ( defined for the users group in radgroupcheck simultaneous-use := 1 ). So far so good, but if i choose nastype=cisco, the user can log in as often as wanted. Checkrad gets executed and logs the following: /var/log/radius/checkrad.log ----------snip----------------------------------------------- Fri Jun 1 15:18:27 2012 checkrad cisco 141.72.65.21 1 machauer(a)staff.dhbw-mannheim.de 4fc8c577/a0:0b:ba:dd:25:8a/44 snmpget: /usr/bin/snmpget -r 1 -t 5 -v2c -c 'xxxxxxxxxx' 141.72.65.21 .iso.org.dod.internet.private.enterprises.9.2.9.2.1.18.1 user at port S1: No snpwalk: /usr/bin/snmpwalk -r 1 -t 5 -v2c -c 'xxxxxxxxxx' 141.72.65.21 .iso.org.dod.internet.private.enterprises.9.10.19.1.3.1.1.3 Returning 0 (login ok) ------------snap------------------------------------------------ If i execute the snmpget command by hand, i get the following: SNMPv2-SMI::enterprises.9.2.9.2.1.18.1 = No Such Object available on this agent at this OID The MIB on this device seems to be different than on other cisco devices :-( Has anyone an updated checkrad version which can get active usersessions from Cisco WLC or a hint how checkrad needs to be edited to do so ? Using nastype=other is no option, because the NAS only sends sessiontimeouts every 10 Minutes and i always have a time lag between radacct sessions and NAS sessions. Help would be really great !
