Cisco :: After Connecting VPN Giving Connection Timed Out Error?

Jul 24, 2011

I had been working on our client servers through Cisco VPN using internet datacard. But from past 3 weeks after logging into Cisco VPN using my username/password, when I try to connect to any of the servers, it is giving connection timed out error.

Whereas, my team members across other locations are able to connect to the servers using my VPN username/password.

I thought there might be some issue with my laptop or internet datacard. I got my laptop formatted, even tried out with fresh new laptops & new internet datacards, but the issue remains same.

I have tried using vpn_5.0.06.0160-k9 & vpnclient- to connect but issue did not get resolved.

Internet Is Giving Limited Connection Error

Apr 22, 2013

I am currently on Time Warner Cable 10 mbps packge, and am using their wireless DOCIS3 modem/router. It is connected in my bedroom to the main computer. That computer stays connected. However, throughout the rest of the house (we have a two story townhome) it will drop completely or give limited connection...constantly. Sometimes I can have my laptop next to me and it will go out or give limited connection. The connection speed never drops, it just goes completely to no connection. Not for sure what is going on, if its on my end or time warner. Has been doing this for quite some time, the cable company comes out and changes the modem, but that's it, couple days later, goes back to doing it again.

AAA/Identity/Nac :: 1841 Giving Error In Authentication

May 15, 2013

I have an 1841 that was working fine - I could SSH to it with my Radius login and console into it with local credentials ("Fred").I added another use ("Mike") with priv 15 so the end user could log in locally via console if needed.After that, we can both log in via console, but when we try to enter privileged mode we get "% Error in Authentication", before even entering the   password.I can still log in via Radius SSH with no problems and access privilege mode via SSH.What am I missing so we can have two different users be able to log in locally with different credentials and access privileged mode, and keep my ssh radius working?

Cisco Switching/Routing :: Nexus 5596 Giving Error In Connection

Aug 28, 2012

I have 2 datacenters running same equipement (two Nexu 5596 with FEX).I just took a look at the log just to see if everything is ok and I saw that I have the same error message (a lot of times) at both location :
%SYSMGR-FEX100-5-HEARTBEAT_LOSS: Service "satctrl" heartbeat loss 2 ,max 7,I though it was a problem with my peerklink-keepalive connection but I see the word FEX i'm not sure...
Note that at both locations, my Nexus are connected back to back through the management port using transceivers. So it's a copper cable from the first nexus,  going into a transceiver, going to another transceiver in fiber and then back to copper to the other nexus.

Cisco VPN :: 3825 - VPN Client Is Giving Error And Unable To Create Certificate Enrollment Request

Feb 21, 2011

We find ourselves in a difficult situation with the Cisco VPN Client version where it keeps giving us an

"Error 42: Unable to create certificate enrollment request"

When we attempt to use the Online enrollment method to create and enroll a new certificate. There is no additional information in the VPN client logs where we have set 3-High for all logs. In addition, Wire shark does not show any packets sent from the machine running the client to the Cisco 3825 router which runs the Cisco CA.
To create and enroll a certificate we do the following:

1. Click on the Enroll button to show the Certificate Enrollment dialog
2. Select  Online
3. Select <New> for Certificate Authority
4. Enter as CA URL (note, is the IP of the Cisco 3825)
5. Click Next to display the dialog where we can enter certificate details
6. Enter details in all fields except IP Address and Domain
7. Click Enroll which shows a dialog with the Error 42 ... message in it.
If we attempt to create a request by using the File method, all works fine, that is, the client creates a file with the enrollment request. The fact that the client does not send any messages to the Cisco CA leads us to believe that we have a problem on the client machine. However, the client does not write any information in the logs, so it is a bit hard to fix the problem. I can provide additional configuration information if required for both the client and the Cisco CA. Note that we have not modified any client configuration. Basically, we installed the client on a Windows 7 64bit machine and attempted the steps listed above.

Cisco WAN :: Licensing For IOS 15.x On 2851 Routers?

Feb 16, 2012

Do I need to obtain license keys/files when upgrading a 2851 to IOS 15.x?  I'm getting a bit confused seeing the documentation that says 1) IOS has gone to a universal image and 2) that feature sets are unlocked based on the installed license.
I was able to download a feature specific IOS image for the 2851 and it did not bother me about licensing upon boot up.
I read one post on here that stated 2800/3800 series (G1) do not have to worry about the licensing piece and that it's just 2900/3900 series (G2) hardware that require it.

Cisco WAN :: 2851 - How To Route / NAT Based On IP With 2 WAN Connections

Mar 29, 2012

I have a Cisco 2851 (with a 4 port switch module) that I am trying to set up with two different internet connections, and have it route traffic out to them based on the source IP. One connection is a 50mb Comcast connection, another is our T1 that our servers are hosted on. The goal is to guide server/phone system traffic to the T1 and have the rest default to the Comcast. I currently have the 2851 connected to our Layer 3 switch (Dell Powerconnect 6224) with a subnet created between them. Static routes have been created on the 2851 back to all of our existing subnets. Traffic flows internally without a problem between the subnets and 2851 (and vice versa). I set up the 2851 with route-map's in the NAT to control the flow of traffic, with the default route set to the Comcast connection. Default route works great, speedtest shows full speeds and everything looks great. The problem happens when I apply my route-map policy to the internal LAN interface with the ACL list of IP's that I want to guide to the T1 (with a next-hop of the T1's IP address). I tested some tracert's and pings from one of the IP's in this list and they would stop at the T1 modem and not go any further. I did a "show ip nat translations" and noticed that the "outside" portion (right half) was blank for every IP that was in the ACL or related to the T1. So my guess is it looks like this is not doing NAT for the T1? I double-checked that I had my "ip nat inside" on the LAN interface and "ip nat ouside" on the T1 VLAN interface and Comcast interface and they were there.
