Fwd: PEAP + linksysWRT54G not working
by alfred hitch 02 Aug '05

02 Aug '05

Hi All, I was having a very simple network for testing, WIN XP (SP2) client, connecting via a wireless router . in PEAP MSCHAPv2 Mode .. Now, everything was working fine with no issues while I was using a D-Link AP, I replaced it with a Linksys Router (WRT54G) and boom boom bang !!!! .. I cannot get even basic WPA-TKIP RADIUS to work. (Btw, My Win XP PEAP is set for asking for credentials and not default use windows domain and password. no server certificate validation ) My observations: Issue 1: After wireless association, router send EAPOL-req. Identiy, 1) If I enter credentials, say pradeep/pradeep .. they go to radius.. logs attached .. radius sends a challenge to router. router doesnt seem to be forwarding this ! 2) If I change above PEAP setting to use domain name .. the exchange goes through but fails at the last step, saying no password found. Issue 2: Even if I assume that linksys is somehow looking for "\\" in incoming username requests, I was trying to configure radius for that. And here is where I need critical help. Is just entering the username in this format in users file ok ? SBNOTEBOOK\\Administrator Auth-Type := Local, User-Password == "sbook" SB_Uplink = 10, SB_Downlink = 20, Session-Timeout = 600, Fall-Through = 0 I have tried all combinations here with "\" instead of "\\" .. turning on with_nt_domain_hack = yes in conf file. I am new and am sure I am missing something very basic here, any help would be appreciated. I am attaching a log from Issue1, step2 and radiusd.conf. Cheers, Alfred

Disconnect-Request packet
by N White 01 Aug '05

01 Aug '05

Ok. I am trying to figure out how to disconnect a user, or to tell the radius server to send a disconnect packet to the NAS for a specific user. This is the command I am using: echo "User-Name = nickwhite" | radclient 192.168.1.1 disconnect mysecret -x This is the debug output from the radius server: ad_recv: Disconnect-Request packet from host 192.168.1.2:47874, id=139, length=31 Unknown packet code 40 from client 192.168.1.2:47874 - ID 139 : IGNORED I also came across this: http://www.freeradius.org/faq/#4.3 But why then is there a command as part of radclient to disconnect, and what does that response exactly mean. Is there any way to accomplish this?(disconnecting a user via radclient?) Thanks -- --------------------------- | Nick White | | nwtech(a)tele-net.net | ---------------------------

Re: XP supplicant and Secure Cerficate acceptance

I think your terminology is incorrect. I know for a fact that Funk's software will not accept a self-signed cert. That is a certificate not signed by another CA. What I think you meant, was a having your own private trusted CA root. Where the server and client certs are signed by it. And, yes, in that configuration you have to install the cert for that CA on the clients, if you want them to verify the server cert. If you can provide me a pointer to the Funk documentation that recommends what you suggest, I would appreciate it.

XP supplicant and Secure Cerficate acceptance
by jck-freeradius＠southwestern.edu 01 Aug '05

01 Aug '05

I am running FreeRadius 1.0.4 and using XP supplicants. My problem is after authenticating against FreeRadius, XP asks me to OK the server certificate. I do not want to manually validate the server certificate. XP should be able to validte the certificate by itself, as long as the cert has been issued by a valid Certificate Authority. I have tried using certs from DigiCert and Verisign. Does anyone else see this same problem? How can this step be automated so that my users are not requried this additional click? --johnk

Problems with Simultaneous-Use
by jck-freeradius＠southwestern.edu 01 Aug '05

01 Aug '05

= This is a re-post. I received no help from the previous posting = Hello, I am having problems with Simultaneous-Use and checkrad. I know that checkrad is not running because: grep debug /usr/local/sbin/checkrad # Config: $debug is the file you want to put debug messages in #$debug = ""; $debug = "$logdir/checkrad.log"; and: -- tail -F /var/log/radius/checkrad.log Fri Jul 29 12:57:30 2005 checkrad Usage: checkrad nas_type nas_ip nas_port login session_id -- (nothing new is showing up in the checkrad log file, except for when I run it by hand) I have both the Perl SNMP modules installed, along with NET-SNMP (and the correct syntax for NET used in the checkrad script, even though it should be using the perl modules first). I am able to manually use snmpwalk /fine/.

access-challenge
by Srinivasa Rao Chigurupati 01 Aug '05

01 Aug '05

Hi 1. Will FreeRadius challenges with access-challenge if auth-type is PAP? If answer is it depends on some configuration, how to configure it? 2. How FreeRadius understands incoming Radius access-request packet contains PAP authentication information, CHAP authentication information or MS-CHAP authentication information or other authentication information? -- Thanks Srinivasa Rao Chigurupati

WRT54GS (sveasoft) with Freeradius 1.0.2
by Rajeev Pokkyarath 01 Aug '05

01 Aug '05

Hello! I am trying to use Linksys WRT54GS with Firmware_Alchemy-6.0rc3lw031 (sveasoft) against my freeradius server (1.0.2). Basically trying to setup a hotspot scenario. But eventhough I enter a valid username/password in the login page, I am not able to login. I ran the radius server in the debug mode and I see that the server is sending the Access-Accept packet (I also notice that it is re-sending it). Instead of my freeradius server, I tested against the server hosted by chillispot, (https://radius.chillispot.org/radius/) (freeradius?) and it seems to be working fine. Any thoughts that might lead me to the right direction? or any known issues?

OFF-TOPIC - ISDN and 56k modem users
by Kinetix 01 Aug '05

01 Aug '05

Has anyone ever used an eicon diva card for a dial-up server?? I have setup such a server using a DIVA 4BRI card in a Redhat box with mgetty 1.1.33 and pppd-2.4.3 Everything worked OK for the modem users. The dial-up server sent a NAS-Port-Type = Async to the radius server But when I tried with ISDN users I saw that the NAS-Port-Type that the dial-up server sent to radius was Async again Has anyone any idea on how to make pppd send the correct type of NAS-Port-Type to the radius server?
