Cisco WAN :: 3845 PPP Authentication Failed With Ms-chap-v2
Dec 20, 2012
I'm trying to connect to ISP with PPPoE method using Cisco 861 equip. On the other side Cisco 3845 BRAS.Session fails at authentication phase. Authentication protocol chosen by routers is ms-chap-v2. Chap supported also. [code]
im having trauble when using chap as authentication for my two routers, i dont know whether my configuration is wrong or not.Is theres anything wrong with the configuration ??note : both routers are c2961
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.
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.
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)
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.
I am having Cisco 3845 series router with c3900-universalk9-mz.SPA.151-4.M2.bin IOS . I want to install new Licence on it for DATA. When i am trying to install licence on it i am facing the error "% Error: License installation failed with error: XML parsing failed".
In my head office we have Cisco 3845 router.in the router we put the show log command the below error is came..
What is the error??why the error came??

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?
I have a 3845 router. Setup SSH Version 2generated rsa keys (1024)set login localtransport input ssh and telnet is enabled since I can't get ssh connection working When I connect using SSH, I get the following error. server refused authentication protocol.
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

I have a guest network and lately I have been experiencing troubles with some users.The symptom, as I create a username and password and type'em in a laptop the authentication fields in the web authentication page don't keep the data as if I didn't type anything
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.
I've just purchased a second hand laptop for my Hubby and trying to gain access to the internet through my SKY wifi router. It keeps saying its within range but this error of Wireless authentication failed because of timeout!
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.
I realize there are a few other threads on this subject. Ive followed some of the advice and I still can not connect. I am currently connected via Ethernet cable but I cannot connect to wireless. I have removed all the stored networks. My event log states: [code]....
When I try to log-in to my D-Link DIR-835 Router using IE9, I get an 'Authentication Failed' error. FireFox & Chrome work just fine. what I need to change or fix in IE9 so it will also log-in to my router?
We have ASA 5520 as SSL VPN concentrator so users can access internal web from outside. Our internal web also has several internet URL. What we want is when user click internet URL in our internal web, ASA forward those request to internal proxy server. I already config proxy using port 8080 and username "companyuser" and password, but always have authentication failed on ssl vpn browser. We uses forefront TMG as proxy. Username and password have right to access Internet.
we have a ACS server V4 installed on W2003 server ,when we make a telnet to an equipement on the wan the authentication pass on the first connexion ,but when we telent to a switch on the lan the first connxion fails and we need to retry to login .when i check the field attempt log on the ACS i dont find the field attempt.i find this issue in ALL switch on the LAN ,from the switch i can ping the the ACS server .this problem appear frequently?
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.
Having an issue where a user will plug a PC into a switch. The switch does a MAB authenticaiton and the MAC is not located in the ACS server. It logs the failed attempt, but when the PC is removed from the switch, the failed attempts keep getting logged until the port is bounced. Any way to keep the attemps from happening after the PC is removed? If not, any way to make it stop without bouncing the port?

I have configured Radius authentication on Windows 2008 server (NPS) The following configuration is working perfectly on Cisco Switch 3560. [code]But, the same configuration is not working on Cisco Catlyst Switch 6509 (C3560-IPBASEK9-M), Version 12.2(46)SE, RELEASE SOFTWARE (fc2)/
I have have a XPS L502X. I decided to make a clean installation based on Windows 7 Ultimate.My problem is when I instal the driver for the "Dell Wireless HSPA 5540" it fails with then warning:
"Authentication failed. The .... driver cannot be installed on this computer...."
I've been configured my device 6506-9 with TACACS+ server authentication: [code]
but when I tried to access the device only uses authentication local but not uses TACACs (with username/password defined) it can be an error in configuration? in the other devices of network this works properly, only it's wrong in Cat6506-E
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.
My 7 inch netbook authenticates to a wifi network with short network key but cannot authenticate to one with a very long key. I am using Win CE 6. The encryption method is AES, the authentication method is WPA-PSK. The short password key is 9 digits consisting only of numbers and letters. The long key consists of 35 digits, with spaces, capital letters, numbers and an exclamation mark.
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.
While the home PC and my brother's laptop can connect to the wireless internet, my sister's laptop has never been able to. The antivirus software installed is Avast! and there is also a Windows Defender. It can connect no problem using an ethernet cable.
Is there any physical or technical diferrences between PWR-3845 AC/2 and PWR-3845 AC? We are trying to order replacement parts and wondering if PWR-3845 AC is for one power supply and AC/2 means you get two with one order?
