Cisco :: CHAP Authentication / One-Way Hash

Jun 17, 2012

How the one-way hash is generated given the challenge number and shared secret password?It's just that I was reading Cisco 3 chapter 7, and it doesn't explicitly outline how the one-way hash is actually generated, it simply states that it is generated given the challenge number (randomly generated for every challenge message) and the shared secret password.

Cisco AAA/Identity/Nac :: 877 - Using CHAP With RADIUS Authentication

Jan 19, 2012

I have configured a Cisco 877 router to send RADIUS requests when a user logs in to the console (Line Console or Line VTY) using the following config:
 
aaa new-model
aaa authentication login default group radius
aaa authentication ppp default group radius
 
radius-server host 10.0.0.1 auth-port 1812 acct-port 1812 key mysharedkey
 
When I log the RADIUS packets I see that the Cisco router is sending the initial AccessRequest using PAP.
 
How can I configure the router to send it's inial AccessRequest packet using CHAP?

Cisco WAN :: 870 Debug Shows Dialer 1 Success Chap But Atm0 Failed

Jan 3, 2012

I have a cisco 870 router which I'm trying to connect to my ISP all the interfaces are in a up, up state. But I'm unable to ping any IP address on the internet. When I do a debug ppp I can see that the username and password are correct with the dialer 1 interface as there is no errors and I can see success. But when I shutdown the atm0 interface and then do a no shutdown I see a message called authentication failed.How does the atm0 interface work with the dialer,Also I spoke to the ISP and they can't see any connection being made but the debug shows success. I also get a default gateway via the ISP but it is the incorrect default gateway as I can't ping the internet and the ISP confirms that the default gateway is incorrect.

AAA/Identity/Nac :: Get ASA 5510 To Use CHAP Via RADIUS Authentication?

Jan 13, 2012

I've setup my ASA 5510 to use AAA to my Windows Server 2008 NAP. After many hours of troubleshooting I got my setup to work. The only thing I'm not satsified with at the moment is, that RADIUS is using PAP for communicating between ASA5510 and W2K8/NAP.I've tried ticking the box "Microsoft CHAPv2 Capable" box under Users/AAA => AAA Server Groups => Edit AAA Server.From EventViewer on W2K8/NAP I get Event ID 6278 and 6272., see attached filehow I change from the PAP to the CHAP protocol?
 
PS: ASA 5510 running ASA version 8.2(4) and ASDM version 6.3(5)

Linksys Wireless Router :: WRT54G V6 - ISP Requires PAP Or CHAP Authentication?

Sep 9, 2011

My ISP here at my mother's in Italy (www.teletu.it) gave me the following configuration:
 
1. Supported Protocol: PPPoE or PPPoA

2. VPI: 8

3. VCI: 35

4. Encapsulation: LLC (If not supported: VCMUX/NULL)

5. Modulation: Multimode

6. Authentication Protocol: PAP or CHAP
 
if I connect my laptop to the ADSL modem, it all works just fine and I can connect to the internet (as you can see )
 
HOWEVER, if I then try to configure my WRT54G v6 to use this internet connection (I NEED to be wireless here, or I won't be able to use my iPhone and iPad), there is no way apparently for me to configure the Encapsulation, Modulation, and Authentication Protocol above. I just upgraded my WRT54G's firmware, and am now running firmware Ver.1.02.8, 10/05/2009. I was hoping this would allow me to set these parameters, but I can't find a way.
 
I tried just configuring the WRT54G with PPPoE and the ISP's userId/password, but this doesn't seem to suffice, and I don't see any other settings I could try.

Cisco VPN :: 3845 - Multiple RADIUS Authentication Groups On Single Windows Server

Feb 15, 2011

We have multiple RA VPN groups on a 3845 router.RADIUS authentication is currently happening between the 3845 and a single Windows 2008 server.  We have a specific windows group that AD users are members of, and they are allowed to connect via VPN.
 
I'm creating a new RA VPN Group, which should only allow different AD users.  Is it possible to create another RADIUS association to the same server, or do I need to authenticate against a different Windows server?

Cisco :: Getting Authentication Failed AP1131

I got a report from a branch office which is getting trouble to authenticate users to the WLAN this is a stand alone AP which has a configuration script that we use for all our branch offices but in this case is not working. It seems to be an issue with RADIUS but if it was the case the whole company would be experiencing problems since it is a central RADIUS server.
 
Here is a log from the AP By the way I modified the radius server timeout to 90 sec

Cisco AAA/Identity/Nac :: 802.1x Failed Authentication With WS-C3750G-24T

Mar 12, 2013

I have already set up a lab  comprising of  1x2950-24 switch, 2x3750-24T in stack mode and 2x MS Domain Controller with AD 2008 Servers and NPS enabled (Domain level 2008). I use NPS as a Radius Server. I am trying to test the 802.1x framework in two scenarios.
 
1.     I use as client a domain laptop with Windows XP SP3 with the embedded 802.1x MS supplicant. As authenticator use the 2950 switch and as authentication servers I use the two NPS integrated in MS DCs. Everything is working fine as I expected with basic configuration guidelines from Cisco & Microsoft.
 
2.      I use as client a domain laptop with Windows XP SP3 with the embedded 802.1x MS supplicant (the same as before). As authenticator I use the 3750 Stack switch and as authentication servers I use the two NPS integrated in MS DCs (the same as before). I have configured the supplicant for both machine or user authentication in both scenarios. However the client never pass the authentication in the second one. I disconnect and connect the same supplicant in the 2950 switch and the authentication is completed successfully. Getting back to the 3750 stack the authentication failed and the laptop gains network access in the configured Auth-Failed Vlan. I have tried several configuration changes without success. I cannot understand why does this happen. I have made some debugs and I am sending them a long with a partial basic configuration of 3750 stack switch.

Wireless Authentication Failed Because Of A Timeout?

May 3, 2011

picking up on old thread, but same issue: authentification failed because of a timeout

*previously*! i was able to auto connect fine on this home network via wifi.the line and box recently changed, same provider, and now i'm the only one who can't connect.the SSID changed, but i've done all the usual routines, deleting and re-adding manually, etc. but nothing so far...

i *don't* think this is a case of changing gear, but i don't know enough about internet/connection/configuration to fix this. yet!

NB: when i perform the reset on the box as instructed, using the provider's setup software - i am not the account holder - for the wifi, it shows connected very briefly in the animation, and then goes off again; this is the authentification/verification failing, i conclude.

so: with what is said above, i'm wondering if my antivir is to blame, or the windows firewall settings.or malwarebytes.i'm going to study the info i've got off my system, and looking at the router via the http routine, offline, as i now have to get off the internet(...); i'll get the infos together so i can post something useful.

Cisco Firewall :: ASA 5510 Server IAS First Authentication Failed

Jun 5, 2011

I have a little problem with my ASA 5510 version 8.2(1) with a IAS server RADIUS for strong authentication.
 
I have configured a double authentication for my client to access SSL portal:
 
First authentication: AD serverSecondary authentication: IAS for my token SAFENET ALADDIN The server IAS is declared on a W2K3 and it's standard.
 
The problem I have is that after more than 24hours of unutilization, when i try to log in, my authentication failed the first time and then the other tries work fine as long as I use it in a period of 24hours.
 
I first thought about the timeout so i tried to put a "timeout" of 15seconds for AD and IAS servers and a "retry intervall" of 3 seconds, it doesn't change much.
 
Is there a tool/option in the ASA to check connectivity with the radius every 1h for example.

Cisco Wireless :: 1042 Autonomous AP - BSSID Failed Authentication

Feb 13, 2013

I am trying to configure a Cisco 1042 autonomous AP and have ran into some problems. I require 2 broadcasted SSIDs that use WPA v2. When I only have 1 of the SSIDs enabled, I can authenticate with no problems. When I have both SSIDs enabled, I can connect to one of the networks, but not the other. I have verified the PSK multiple times, but the logs still show  dot11-7-auth_failed. If I remove the working SSID and make no changes to the SSID for which authentication previously fails, everything works fine. Upon adding the other SSID back, I run into the same authentication issue.

Cisco AAA/Identity/Nac :: ACS 4.2(0) Build 124 / Failed To Initialize PEAP Or EAP-TLS Authentication Protocol

Oct 31, 2010

I replaced an ACS certificate that had been installed as follows:

1. Generate CSR file and private key file, then send CSR to GeoTrust (Key length: 2048 and Digest to sign with SHA1)

2. GeoTrust send me a certificate. Issued by "GeoTrust SSL CA".

3. Install the certificate on the ACS. Restart ACS service.

4. ACS Certification authority setup. Issued by "VeriSign Class 2 Public Primary Certification Authority - G3"

5. Edit certificate trust list and select "VeriSign Class 2 Public Primary Certification Authority - G3" as trusted.

6. Enable EAP-TLS, then restarted the ACS service. The problem is when i try to enable EAP i get the error msg:Failed to initialize PEAP or EAP-TLS authentication protocol because CA certificate is not installed. Install the CA certificate using "ACS Certification Authority Setup" page.I searched on cisco and it said to disable the CSA, but in fact there is no CSA installed on this server.
