Access-reject tiemout
by Patrice TCHERKEZIAN 02 Aug '05

02 Aug '05

Hi !, I experiment a strange problem which have appeared since some weeks. All Access-Reject sent to my AC/AP by the radius server take a lot of time to arrive and there is a timeout on my AC/AP. This is very strange because all Access-Accept are well-received without any timeout and any error by the AC/AP. And, I test on my lan with Ntradping, and the same problem of timeout appears after an Access-Reject. But also, when I launch Freeradius on debug mode, there is no timeout and all Access-Reject are well-received. This is the configuration I use : freeradius 1.0.3 database : Postgresql release 8.0.3 Access Controller/Access Point colubris(CN3200) Thank you for your help.

Session-Timeout zero value

I'm wonder is it correct to reject user by setting Session-Timeout attribute to zero. In case of our NAS it works fine.

Firefox and Opera are also broken in that case. :-( A bit of a dig around reveals this from the Apache site, which implies that all browsers cache the credentials. http://httpd.apache.org/docs/howto/auth.html#basicfaq Thanks, Jezz Palmer.

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
by David Mitton 01 Aug '05

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
