All HTTPS Sites Failing Validation

Apr 1, 2011

I just put together a new computer. After putting it together I installed Windows 7 64-bit. My problem is that every "https" website I go to fails at its certificate validation. Every browser I use (Firefox 4, Chrome, IE9) warns me that the security certificate failed the validation. If I click "continue anyway" the browser shows a blank page. This happens for every https site. I have tried,,, etc. I can't even connect to windows update (which is really bad). The problem is limited to this computer. All my other computers (2 laptops with windows 7 32 bit) connect to websites using https just fine. My computer is freshly installed, but I scanned for spyware/viruses/trojans and came up empty.

Cisco Application Networking :: ACE20-MOD-K9 HTTPS Probe Failing Randomly

May 13, 2013

I have a physical server running behind the ACE module ACE20-MOD-K9. The Server has several virtual machines. One of that virtual machines, has a WEB SERVER running virtual https servers. For example, server with IP address, has serveral virtual HTTPs servers as of urll... So, if you nslookup the servers, they all respond with IP address. So if I do url...goes to and read the VIRTUAL SERVER config and replies back to the request.Now, I am trying to verify that the TCP connection (443) and the HTTPS server itself is up and running but only for the url... site and not for the other 2.The problem that I am facing is tha the HTTPS probe fails randomly. The TCP probe works fine.

Routers / Switches :: Can't Access Any Https Sites

Oct 25, 2011

when my Linux VM is running!How's this for a mystery - last night I noticed that I could no longer access my gmail. Thought it might be down. This morning, I still couldn't access it. Thought I would try comcast, no joy either. Changed computers, no difference. Changed routers, no difference. Bought a new router and started plugging in network cables one at a time. My main machine first, everything works - http and https sites, a second computer, all good. The switch. Fine. Powerline. Still good. Then I plug in a Windows server running a Linux VM. Https sites on all the other machines stop working. Pause the Linux VM, restart router - https sites return to life. Went to Linux machine, re-enabled ipv6 (the only recent change on the Linux machine was to disable ipv6 since upon a reboot, Linux didn't have an ipv4 address). Restart Linux everything seems fine. A few hours go by, try to connect my wife's new laptop and at that moment wireless seems to stop. Restart router, wireless is back. But lo and behold, https is gone again. Unplug the machine that has the Linux VM, restart router, all is good.Ever see anything this weird?

Cisco VPN :: 2811 HTTPS Sites Hang Through Web Vpn

Jun 27, 2010

Using webvpn on a 2811 w/ adv ent 12.4(20)THTTP sites work fine (in the url-list)
But when we try to use an HTTPS site, clicking on that site just hangs forever.  Debugs show the connection is making it, and the servers are getting the connections...
The destination servers are using self-signed certs, as well as the router.  They are not requiring client certs.

Cisco AAA/Identity/Nac :: CRL Validation Fails On ACS

Aug 11, 2011

We are using ACS v5. in 802.1X certificate based authentication. Now, when we added CRL functionality into ACS it fails in CRL validation and gives following error message:
LastErrorMessage=CRL PKI verification failed
Certificate Revocation list [URL]
We have installed root, device and server certificates from CA, but for management we are still using self-signed certificate.
Question is, which certificate is used when validating downloaded CRL file - one used for EAP-TLS or one used for management interface?
How I can check which certificate ACS server is using for CRL validation?

Cisco VPN :: 5510 - Certificate Validation Failure With AnyConnect Only On MAC

Apr 2, 2012

I have an anyconnect account set up using version 3.0.5080 and connecting to an ASA 5510 base 8.2(2)17. We are using certificates for authentication. If I try and use the account on a windows machine it all works fine.
However on a mac running Lion if I try and connect via a web browser or already have the anyconnect client loaded and try to connect I always get “certificate Validation Failure”. I double checked the certificate was correct and am sure that is correct as it is the same certificate on the Windows and the mac. After searching online I have also tried editing the anyconnect profile to so it is set “certificate store override”, and put the certificates and key in the “user/.cisco/certificates” and  “/opt/.cisco/certificates” folders.
After further testing, if I change the anyconnect connection profile to “authentication aaa” I can connect fine. Then if I disconnect, change it back to “authentication certificate” I can connect fine the first time, but all the following subsequent efforts I make fail. If I repeat this process this happens each time, I can connect the first time but after that it fails with the same “certificate Validation Failure” error message. When it connects this first time I checked and confirmed that it is definitely using the certificate. I have also tried using both authentication methods (“authentication aaa certificate”) and had the same problem.
This leads me to believe that my configuration is correct and it is some bug in the anyconnect client or the ASA image. I have had a look through bugs and read somewhere that there was a bug on earlier versions of 8.4, but nothing about 8.2.

Cisco VPN :: ASA 8.4.5 - AnyConnect Web Install Getting Certificate Validation Failure

Mar 21, 2013

I have an ASA (8.4.5) configured with a connection profile that does AAA and Certificate authentication. Once I have the anyconnect 3.1 on a win Xp system, it works perfectly. When I do a web install, it goes through the normal download, log-in, re-download then says "Certificate Authentication Failure" If I change the profile to AAA only, it installs fine. I even get the error if I launch from the web after I have the client on the PC. Why this is not working?

Cisco :: WLC 5508 / Guest User Session Validation Failed

May 31, 2012

I am running a guest wireless network on a Cisco 5508 WLC with code. My syslog is filling up with the following error message:

WLC: *May 15 12:32:59.244: %AAA-3-VALIDATE_GUEST_SESSION_FAILED: file_db.c:3968 Guest user session validation failed for guest_user10. Index provided is out of range..
The user that is assigned to the guest_user10 account works fine and has no idea this error is occurring.
This error message is occuring exactly every 15 minutes 24x7.
I believe I have a rogue user who has setup a device to try and login to the guest network automatically, every 15 minutes with the guest_user10 credentials. I need to track this device down. I need a way to find either the MAC or IP address of the device that is causing this error message. I have tried turning on AAA debugging on the controller but I dont get anything more than the above error. I have also tried using WCS to look at the client history but it only show the normal activity.

Cisco AAA/Identity/Nac :: %ASA-3-717009 / Certificate Validation Failed / Certificate Date Is Out-of-range

Jan 30, 2012

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?

Cisco AAA/Identity/Nac :: ACS 5.x Identity Store Sequence And Token Validation

Dec 3, 2012

We have a ACS 4.3.2 installed with users authenticating against an Active Directory database. The AD database not only authenticate the users but also assigns the group that is used to select IP address pool.Now the requirements require to use token authentication with SafeNet. This authentication uses the same username but the password is composed of the original password + OTP.The problem is that the SafeNet server doesn't return the group membership.I've read about the Identity Store Sequence in ACS 5.x and I think I could use it in the following sequence:! configure an Authentication Sequence using the SafeNet token server (this works with ACS 4.x)I configure an Attribute Retrieval Sequence against the AD database. This would use the username only, no password and would retrieve the group membership.

SFTP Connection Failing?

Dec 4, 2012

I set up a connection from a laptop (Windows 7) that goes through a LAN proxy server to a secure ftp server (Windows Server 2003).The sftp server is assigned a public ip address.I opened the firewall at the destination and allowed port 22 traffic to the sftp server. Well, the connection is failing.I know for a fact the connection from the client laptop is making it to the sftp server.If I issue this command on the client laptop:

telnet sftpserver 22

The DOS screen clears and tells me the type of SSH server I'm connecting to. While this connection is still active, I logged into the destination sftp server and did a netstat command. I can see the address of the proxy server in the "Foreign Address" column of the netstat results. I also can see the proxy server address when I look at the Application Log on the sftp server, so I know the connection is making it to the sftp server.

I beleive the problem is the control port (return traffic) from the server back to the client. Something is being blocked or is misconfigured. I always thought the router negotiated the control port, and that the control port didn't need to be put into any firewalls.

D-Link DIR-655 :: UPnP Failing In 2.07 And 2.10?

Jan 14, 2013

UPnP seems to be failing somewhere between a few hours and a few days.  It will work as expected for a while after starting or restarting the router, but then trying to create any new UPnP mappings will fail, and the ones that have been already created usually stop working.  The commandline client upnpc fails to locate the router automatically, and manually navigating to in Chrome returns a connection reset error instead of the expected XML device description.I turned on debug messages in the logs, but there doesn't seem to be anything useful in there (though they also seem to be flooded with a bunch of IPv6 mDNS network hopping, so I'm going to try disabling that for a while and see if that works).  I did update to 2.10 and still had the same issue with UPnP, however my wireless network kept going down (I guess a known issue) so I downgraded back to 2.07.  After the downgrade, I reset the router and manually re-entered all my settings (i.e. I didn't import them).

Cisco VPN :: 891 - VTI Failing And Not Reinitializing

May 1, 2011

I'm running a Cisco 891 it has both crypto maps and ipsec VTI's running on the external interface. The cryto maps are for sites that do not have a cisco router and the Tunnels are for the sites that use crypto maps work perfectly fine. But I much prefer using unnels as it gives a routable interface, ospf works ect.
The tunnel interfaces will periodicly fail (Line protocol down) at no set interval, they will then not come back up again. To bring them back up I either have to shutdown and then re-enable the interface or run "clear cry ses rem *.*.*.*"
Logging with isakmp and ipsec errors provides the following:

Continuously Failing ISP / Internet / Network?

Oct 7, 2012

I have recently moved in a new apartment. At the building there is something like a centralized internet. There is a huge machine which is connected to every apartment of building via a cable modem(Netsys nh-300sp). Here is an image of system. And when I first came to apartment they gave me a username and password which I made login when i firstly opened a page on safari. When I plug in an ethernet cable to my macbook-air it connects and everything s good for a moment then it starts to kick me out randomly and continuously. When I look to Network Diagnostics: ISP is red, internet and network are yellow.I tried also using a manual DHPC address, but then ISP is green but Internet and server are red or yellow. I cant even reach to modems admin panel, maybe because of the system of building.
