Cisco VPN :: UC520 SSL VPN Failed To Validate Server Certificate
May 17, 2012
I've configured in an UC520 a SSL VPN.I can access properly and I can see the labels, but I only can access urls which are http, not https:I can access the default ip of the uc520 (192.168.1.10) but When I try to get access to a secure url I get the msg: Failed to validate server certificate I'm trying to access a Cisco Digital Media Manager, whose url is URL Does the certificate of both hardware has to be the same?
i have windows 2008 R2 as CA server. and i also have 2911 router as remote vpn server. Everything works fine for desktops computers and leptops. Users automatically enroll certificates on Microsoft CA server and get connected to vpn. But problem is with ipads. When i try to connect from ipad error massage deslpays "Could not validate the server certificate" and i also get chis error massage from router "CRYPTO-4-IKMP_BAD_MESSAGE: IKE message from x.x.x.x failed its sanity check or is malformed"
With ipads built in vpn client i can see the installed certificate and use it but with anyconnect client no certificates are displayed.
I have some iPhone in my company and they connect to VPN through an ASA (version 8.0.4). The vpn connection use a certificate to validate that the device can connect. All my devices used the ASA IP address to connect, I decide to change that and use a name to connect ( DNS resolution made by the ISP), a generate a new certificate and made a new vpn connection profile. My PC, mac book pro can connect using the new connection, but my iPhone display the message : "Could not validate certificate". I've checked all the configuration and can't find where the difference between my two connection profile.
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'm currently in the process of the setting up a new wireless network and I want to test out our 7925 phones on it. When I try uploading the certificate to the phone it fails and I find the following error in the trace logs
[code]...
I created this certificate using using Windows Server 2003 and it is 2048 bits. This certificate works fine with my laptop but I'm unable to upload it to the phone. The app load currently on the phone is CP7925-MFG-D.8.LOADS. Are there any specific guidelines out there when creating a certificate for a Cisco 7925 phone?
I am trying to install a digi cert on a 7921 and I get the message on import of "certificate verification failed".as there does not seem to be much documentation with the above error message.
I got error message when I convert to certificate authencate via tunnel group.
error message: "certificate validation failure"
client prompte me that "your client certificate will be used for authenticate" but none certificate list popup even i disabled "autpmatic certificate selection" preferences.
some information about my configuration : ASA 8.2(2)4 Anyconnect VPN 2.5.1025 authentication against aaa is working
some key point: ASA: ssl trust-point remote.apac outside
We have enabled EAP-TLS authentication for our wireless LAN end user in our network setup , And we have defined certificate on our old acs server 3.3 from a third party CA . I want to use the same certifcate which is being used in 3.3 ,how i can copy that certficate from 3.3 and get it installed on new acs 4.2 .
Is it possible to use Server 2003 SMB with IAS WITHOUT a certificate? So someone with a laptop could get on the WLAN with their AD credentials without me giving them a cert?
I'm in the process of setting up PEAP with ACS 5. From understanding the certificate that I generate is a server side certificate used between ACS and CA authority. However, according to the Cisco document that I'm using it sounds like I still have to install a certificate on the wireless clients that validate the server certificate. Is there a process to push this cert out via AD or do I need to manually install it and if I wanted can I get away with out checking the validate the server certificate on the wireless client?
RV042 router is giving out the outer certificate instead of server certificate. Outlook anywhere is failing and we are receiving certificate errors for any secure site behind this firewall. I'm not talking about remote management. I'm talking about people trying to access our web site, which is secured, and getting an error because the RV042 is giving its own SSL certificate instead of the Server's certificate. Firmware Version: 1.3.13.02-tm. I don't see any updates for that hardware. I do have it working on an RV042 with the same firmware at a different location. How do we turn that off or keep it from happening? Output from a test site Attempting to resolve the host name xxxx in DNS.The host name resolved successfully. Additional DetailsTesting TCP port 443 on host xxxx to ensure it's listening and open. The port was opened successfully. Testing the SSL certificate to make sure it's valid.

Just installed RV042 router. And it's giving out router certificate instead of server certificate so people who are trying to access our secured server are getting errors. I'm not talking about remote management. I'm talking about people trying to access our web site, which is secured, and getting an error because the RV042 is giving its own SSL certificate instead of the Server's certificate. How do we turn that off or keep it from happenning?
The RV042 firm version is v4.0.0.07-tm (Aug 19 2010 19:19:50)
My customer has SSL certificate already installed on microsoft exchnage 2010 servers and now wanted to import that certificate to cisco ACE4710.
How to trace the exact procedure to import the SSL Cert to ACE from microsoft exchange server and how about the KEY, from where I should get the KEY to cross verify for SSL Cert?

I am constantly getting error on UC520W Wifi from last Night, I am not getting with this error. What is the cause of this error, or is there any issue on UC520. [Code] .........
I bought a new WRVS400n recently because it had Gigabit speed, wireless n and a built in VPN server. The device works perfect except for the Quick VPN client. I'm a system engineer so I thought I could set it up quite easy just like any other device I configured in the past. Painfull but it isn't like this.
I set up the VPN on the WRVS4400n and generated a certificate. I saved both the client and admin certificate to my pc, I gave them a name to easily make up the difference between both of them. When placing the certificate in the installed QuickVPN folder, it doesn't seem to get recognised by the QuickVPN software. When I try to connect, it says 'Server's certificate doens't exist on your local computer'. I guess the naming convention must meet some kind of format, is that correct? If so, this should have been described in the documentation.
Besides that I checked if the required ports used by the VPN server are open on the public port of the device, that is the case. So It seems I'm quite close to get it working.
The version of QuickVPN I used is 1.4.2.1. The WRVS4400n has the latest firmware loaded.
I have a server that I lease that is hosted at a datacenter. Our company is going to lease a half rack and put our own equipment in it as well as a disaster recovery site. The problem is that the one server I mentioned has SQL on it and we have applications that were devloped in house ages ago that hit that SQL instance. Those applications are hard coded to the IP address of that server. We could just change it in the code, but the source code for one of the applications have disappeared over time. Now that you know my situation, my question is this. Can I make a NAT rule or something that says when traffic is destined for xxx.xxx.xxx.123, to re-routes it to xxx.xxx.xxx.321? Currently our endpoint device here is a Cisco UC520. The other end we have no control over.
I am trying to setup time service on two devices. Once is a UC520, the second an 1840 router. I would like to use the FQDN of the time server which is north-america.pool.ntp.org. This is the recommended procedure as per ntp.org due to changes of IP addresses of time servers.
On the UC520 this is not a problem. I type in "ntp server north-america.pool.ntp.org" and this is how the command stays in the config. On the 1800 the FQDN is resolved and inserted into the config as an IP address. This works for now but kinda defeats the purpose of using a FQDN.

I received a message stating: Info-error attempting to validate the winsock base providers:2 Error- Not all base service provider entries could be found in winsock catalog. A reset is needed. Info- Redirecting user to support call I did the reset in command prompt as I read you told other people with this problem to do. But I still keep getting these messages.This is my sister's Dell Latitude 620.I used AVG and I think pc is clean. When I try to connect to a website page states that Internet Explorer cannot display the webpage.
i have an ASA 5510, i configured a ssl portal acces for my company. it used to work. now, it's still half working : 1/ i can connect to the web ssl portal page with the AAA acces (login and psw) 2/ but after, it's no more possible to access at corporate web pages, like intranet, always the same message : "connexion failed - serveur xxx not available". See the attachement.
i watched logs, my packets are dropped but i don't know why.
When we connect an Cisco 7971g and an pc everything is working fine. But when i start wireshark on the pc behind the phone you see a lot of UDP Traffic source UC520 destination 239.10.16.8 or 239.10.16.16. At this point i m getting confused. So i start looking for the cisco phone config, VLAN ID on the phone is 100 (i think that is ok) but the PC-VLAN part is empty?
The main thing is, how can i stop this cisco-sccp traffic on the pc port (prtg shows me a average of 200 kbit/s) i think it is an config fault.
I have a Windows XP laptop and a Windows 7 desktop. The desktop has no wifi support, I had built it myself. To get internet on my desktop (used for games), I had connected my laptop to the pc, and the laptop picked up wifi from my AT&T gateway in another part of the house. ( I can't move the gateway currently) I have been wanting to connect the desktop to a router/repeater/bridge that would pick up my gateway signal, therefore eliminating the use of the laptop. I also have an Xbox right next to the pc, so I din't want to get an adapter because then I would have to purchase two, so I picked up a a wireless n router with 4 ethernet ports. ( then I could connect both systems using 2 ethernet cables) [URL] I knew when purchasing the router that it had repeater/bridge support. Currently, I have it configured as a wifi bridge. I can connect to it via my laptop, on the wireless networks page, it shows my gateway signal, and the bridge/router, so I connect to the router. It says I have excellent connection, but I can't connect to the internet? Using Google Chrome, it says DNS lookup failed. I can't get on any website, only the router's config page, which is 192.168.1.1. I also connected the router to my pc, and when troubleshooting it says DNS server not responding, may be non existant or incorrect?
Trying to set up remote access to webcam. Signed up with dyndns.org for Hostname, but when I try to set up the DDNS Service Settings in the webcam firmware it continually gives 'Bad reply from server' and I'm pretty clueless when it comes to networking! As far as I can see it requires a User name and Password plus the newly acquired Hostname as shown [URL]
My wireless internet at uni is showing up with two errors, when its connected it will come up saying that there is an ip address conflict then it will work for a short time then show this message when I try to load a webpage:The server at Google can't be found because the DNS look-up failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing*Google Chrome*from accessing the network.
I am having a problem using my Windows IAS radius server to validate management users for my 2112 Wireless Lan Controller.I have defined the radius server and it works ok with the policy for validating wireless clients but not for WLC management users.The Remote access policy seems to be set up correctly as the event viewer on the server shows:-
*Feb 09 11:06:06.612: %EMWEB-1-LOGIN_FAILED: ews_auth.c:2104 Login failed. User:xxxxxx. Service-Type is not present or it doesn't allow READ/WRITE permission..
I have one server-A(windows 2008) installed one application called"host front" which gives athentication to connect Linux(mainframe console)server(SERVER B). These 2 servers are bihind the firewall.If one internal user who has the athentication to logine server-B ,tried to login server A,will get the" username and password"screen and once they enter the username and password ,will get the server-B screen.But if somebody try to connet via MPLS(we need to test MPLS site customers) from outside via ASA 5540 ,to server-A will get the "username password" screen and once enter the credentials,after 1 minitue will get error"http server faild to send datas to the server" and will not move to server -B screen.Where do you think is the problem?
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.
I have numerous phones and laptops that connect to the router just fine and fastThis ASUS laptop (windows 7) with Centrino N6150 is very slow to validate. At least it appears that's the issue. The icon in the tray starts with a ! in the connection, then in about 45 seconds goes to a blue chase circle, then in about 45 seconds connects.istory. I was getting disconnects from the WIFI router on a continual basis. I decided to put the router back to factory settings, did the pin reset etc, did a full setup and now we have this slow connect issue ALTHOUGH I never get a disconnect if I once get connected. Just seems to take forever to get it to connect.I've looked at conflicting IP's, no avail, seems fine. As mentioned, like the iphones connect almost instantly. The HP laptop connects fast (windows 7) but the asus now isn't happy.
I have been hacking at this problem for two days and can not figure it out.I built a new computer ASUS M3A78-T and installed windows 7 64bit everything was working fine. I did not validate the version of windows because I was waiting to replace the 500g hard drive with a 120 ssd. By the time I recieved the ssd windows validation time had expired, I tried to validate the version of windows and I could not because the network adapter was now gone! This is strange because when I first built it it as fine and I was all over the internet via broadband ethernet cable.Now the internet box has a red x and will not recognize the cable and no lights are flashing on the back as well. It seems I ned to reinstall the driver so I used another computer and downloaded the only LAN file from ASUS website and nothing.
