Today I installed a new SSL certificate for the management website. After the install the management process continues to hang in initializing.
I can stop the process and start the process again but it never gets passed initalizing.
I have a problem getting my ASA 5520 boot properly. I first though of a flash problem and did a flash erase in ROMMON, then it brought error 15 during boot (No images found in / Error 15: File not found). I then TFTPied and image from Rommon, when done loading the image and start booting, the system hangs and nothing else. Attached is the screen I got on my console during boot up. BTW, the system was in the same state before I undertook any of the above actions. I don't have a service contract, so I can't contact TAC.
View 3 Replies View RelatedI have a doubt about CiscoWorks. I need to generate the self-signed certificate with a key of 2048 bits to generate a CA with VeriSign. CiscoWorks do this automatically with a key of 1024 bits and I do not find a form to elect a a diferent key. Is it possible to generate a certificate with 2048 bits key?
Another problem is that I have CiscoWorks installed on Solaris. Many times at day the web application does not work and the only way to recuperate it is with the command "init 6" and I have to way 15 minutes until I can have access again. Why is produced this error? Who can I fit it?
There is ASA with remote access VPN and users are authenticated using third party signed certificates (CA is not local in ASA).When user certificate expires i can see it in syslog messages. For example:
%ASA-3-717009: Certificate validation failed. Certificate date is out-of-range, serial number: (...)
I would like to know if there is an opportunity to view user's certificate expiry date beforehand, say, 3 days before?
i am working on ISE 1.1.1, surprisingly i couldn't found certificate authority certifiate at certificate operation anymore.
would it be the change on GUI? So now where i can import the CA certificate to ISE?
I've been wrestling with a Windows XP reinstall that wiped out my network adapter. Fortunately I found D-Link AirPlus Utility and have restored it. However, now it says that windows was unable to find a certificate to log me on to the network, although I have entered the correct key.

I need to enable Management access to FWSM using CA ssl certificate.
FWSM Version 3.2(5) in Cisco 6509 switch.
Got to know how to generate, import and export certificate but my query is how to get it applied to the management ip do i need to apply in the management interface.
i was connected to my rv042 via remote management / browser, and tried to add vpn clients. i generated a new certificate and then i clicked on export for clients. by doing this, the remote management disconnected and i cannot access the router anymore.
how can i get the new .pem file from remote? do i have to make somebody turn off and on the unit to get back remote access??
p.s.: after turning off an on i tried the same steps again: everytime i click on "export for admin" or "export for client", this kills the remote management and the unit must be hardreset. now: how do i get the newly created client certificate off that unit ?? otherwise i will have to drive 350 km just to grep that file ?!?!
I have a simple ASA, ACS, AD schema for RA VPN authentication. All is working for a few months now, but since the initial deployment we have this connectivty issue regarding ACS and MS AD. At random intervals, 1 month/1 week, the ACS connection status becomes "DISCONNECTED" although the CLI shows that ad client is running. But because of that, no RA VPNs can be authenticated. Clock is not a problem, since it didn't change automatically nor was manually configured prior to the malfunction.

I am working on implementing ACS appliances. All working ok, until I try to add an attribute to the Shell profile (priv-lvl = 15). When I do this, the runtime process shutsdown (on both primary and secondary devices) and no further device authentications can be made. I can reinitialise the database without issue at the moment, but I'd like to know what causes this and how to prevent from happening in the future - when the database will becoem much more critical.Do I need to raise a TAC case?

Currently I'm using a self signed cert issued by ACS. We are having an issue where occasionally we see in our Windows 7 logs that Windows did not like the self signed cert from ACS when doing dot1x authentication for our Windows 7 clients. We are using the built in dot1x client that comes with Windows and have the "Validate Server Certificate" unchecked but still see this error occasionally. I've tried issuing a CSR from the ACS server and going to Thwate and getting a test cert but everytime I paste the CSR into the field at Thwate I get an error about invalid cert type. You have to choose from a list of server types. I've tried several different ones. I've also tried issuing the request from a WIndows server and when I try and import the files I get a invalid key error. How to get certificate working from Thwate or Verisign?

View 7 Replies View RelatedBeen tinkering around in our ACS 5.2 appliances today to setup PEAP. I generated a self signed certificate under local certificates which I want to remove now. But when I try to delete it I get the following message:
This System Failure occurred: Certificate is associated with a protocol. Hence it cannot be deleted.. Your changes have not been save. Click OK to return to the list page.
I assume this is because it is associated with the EAP protocol, but I cannot uncheck the box when I edit the local certificate. How can I get rid of this test certificate?

View 3 Replies View RelatedWe use a combination of Cisco ACS and Cisco catalyst 3560 switches for network authentication and authorization. Clients (Windows XP) have a certificate installed which will grand access to the network and put them in the correct VLAN. So far, so good. Some users are testing with Windows 7 in the same set-up as above and run into strange behaviour. The problem is that after a random timer the machine gets de-authenticated and nothing besides a reboot works to get the computer authenticated again (from a Windows point of view). It looks like this only happens to users who are using a certificate to authenticate, Windows 7 MAC bypass users have no such problems. If it occurs, the following logging appears in ACS: [code] We are using ACS 4.2(0) Build 124 and 3560-48PS switches with IOS 12.2(55).

we currently have a remote access asa setup using Anyconnect with self signed certificate, and several users in the certificate database as we are using radius and certificate for authentication.

Currently the ACS 5 is authenticate the iPhone/iPad by using the MAC address (which is entered manually) and AD user/password, i need to do that with certificate, so it will be scalable.

Checking the configuration of the Wireless Notebook no longer requires the digital certificate of the ACS and NVR122 NVR123as worked in the past. The certificate is generated for the ACS root CA trusted by the COMPANY, so that the public CA certificate supersedes theprevious ACS.
