Cisco ASA delay listening to the output of the command
Dear,
I use ASA5520 active failover / standby... when connect us via the console or telnet and write the command ant 'show', it's very slow displaying output!
Thank you
Majed
OK, so the ASA is configured with AAA, more specifically from GANYMEDE + more, you stated that the AAA server continues to show up as down and upward, then again. I think that it is the cause of your problem. When you try to run a command, the ASA try first check on the AAA server and after it times out it refers to the secondary database, which is the local database in your case. So eliminate it that do one of the following:
1. Remove GANYMEDE + Associates configs and rely on the local database for authentication and authorization
2. understand why GANYMEDE server + is not available / bounce
Thank you for evaluating useful messages!

Cisco ASA, connect an IP address on the OUTSIDE of the VPN remote access
Hello
I tried to find resources on the net but could not find a solution, then post it here. Maybe someone can help.
So the problem is that I'm trying to access a server on the cloud for remote VPN access (cisco asa 5510).
The server on the cloud (54.54.54.54) is only accessible from the outside interface (192.168.11.2) NY Firewall (cisco asa 5510)
I added some ACE for this in the ACL of VPN tunnel to divide.
NY-standard host allowed fw # access - list vpn_remote-customer 54.54.54.54
And I see the road added to my cliet machine after the VPN connection, but still it cannot connect to this server.
The network INTERIOR, I can connect to the server.
Thanks in advance.
Hello
This is most likely a problem with NAT hair/U-turn hairpin.
Will need to see the configurations or you would need to check yourself
I don't know what your version of the Software ASA is to be like who determines what is the format of NAT configuration.
So far, you have confirmed that the ASA VPN configuration provides the VPN Client with the route to the remote server. Then in circulation should be tunnel to the ASA.
Then, you will need to check the output of this command
See the race same-security-traffic
You should see the command in the output below
permit same-security-traffic intra-interface
If you do not, you will need to add it. This effect of controls is to allow traffic to enter an interface and exit through the same interface. In your case this applies to Internet VPN Client traffic to the remote server as it between ' outside ' and spell through the 'outside'.
Then, should ensure that dynamic PAT is configured for the VPN Clients.
8.2 software (and below)
You most likely have a dynamic configuration PAT like that on the firewall, if levels of above running software version
Global 1 interface (outside)
NAT (inside) 1 0.0.0.0 0.0.0.0
In this situation if we wanted to add dynamic PAT for a pool of VPN, we would add
NAT (outside) 1
This would allow users to use the same public IP address as LAN users, when accessing the remote VPN server
Software 8.3 (and above)
Because the NAT configuration format is completely different in the latest software, you could probably just add a new configuration of NAT completely without adding a
network of the VPN-PAT object
subnet
dynamic NAT interface (outdoors, outdoor)
Of course, its possible that there could be some configuration NAT already on the device which could cause problems for this configuration. If this does not work then that we would have to look at the actual configurations on the ASA.
Hope this helps
Let me know how it goes

How to configure ASDM Cisco ASA 5505
I have a Cisco ASA 5505 firewall, and currently it is a command-line firewall. I want to configure ASDM so that I can use it as a Web based GUI interface.
I don't really know what to do. Can someone help me please how I can configure ASDM on my firewall.
Kind regards
Naushad Khan
Hi Naushad,
First of all, must load the image ASSDM on SAA and then use the command:
ASDM image dosk0: / asdm645.bin (if the image name is asdm645.bin)
then:
Enable http server
http 10.0.0.0 255.0.0.0 inside (if your machine is 10.0.0.0 subnet behind inside the inetrafce)
Go to the machine, open a browser and type:
It will open the GUI.

Cisco VPN 3060 - Cisco ASA conversion
We are about to embark on the passage of all extensions L2L and network (Cisco ASA 5505 s) of the Cisco VPN 3060 concentrator to a Cisco ASA 5520.
We bsemblable woul to see if there is a simple method to do this as a converter? Also, there are lessons learned? We run 8.4.3 so that we know that the NAT configuration has differed. The 3060 configuration can be changed in anyway for help in configuring the ASA?

Addition of Compact Flash in a Cisco ASA 5520
I'm trying to install a 512 MB COmpact Flash for an ASA 5520 Cisco. We inserted the compact flash, but when we do a DIR, it does not show. even as an unformatted device.
What should we do to make this a usable CF? I just need to recharge the ASA or do I need to format the CF. It was inserted into the slot in the back of the ASA 5520, and we ensured that had been properly rests.
Thank you
Dwane
I can hot flash player? For example, is it possible to change the flash player when Cisco ASA is turned on and running?
It is always recommended that you turn off the Cisco ASA, while you insert the flash drive. This disables all working processes and allows the ASA to recognize the flash from the startup process.

Cisco ASA IPSEC from the understanding of a site to tunnel auth using certificates
assuming that my company and another company (BBT) attempt to set up a tunnel to a site by using certificates. lets say we have asa 5520 s and have agreed to use says that our certification authority.
On my end, I do registration certificate using SCEP Protocol and suggests that the end BBT is set up exactly the same way.
First, I generate a pair of keys RSA - Im assuming that it is key to my ASA public private for the encryption and decryption-(pls correct me if wrong Im)
Then I set up a trustpoint to registration certificate (in this case, it will be Server CA Entrust). I will set up my full domain name and the parameters of CRL.
Then, I get a certificate of the AC CA. This package contains a fingerprint of the certificate which is loaded on my ASA. apparently - the fingerprint of the certificate is used by the 'end' entity to authenticate the received CA certificate. Why would the final entity to authenticate a CA certificate that has already been installed on this subject?
In other words, what really does this print? Surely this cant be the same footprint that GETS installed on the BBT ASA?Finally, I request and install a certificate of identity. It asks for a password? I believe that it is used in case I want to make changes to the certificate, such as the revocation of the certificate. (Once again, please correct me if wrong Im)
a few additional questions
during the phase of authentication isakmp how my asa verifies that the certificate that the ASA BBT sent was indeed signed by the certification authority approved. How exactly?
My ASA and ASA BBT must trust the same CA. In other words, it must be set up the same trustpoints?
or can I have to entrust CA server as a trustpoint and verisign?How the certificate authentication process works since the ASA receives valuable traffic through the exchange of encrypted data?
1 million thanks!
Hello west33637,
You can read this document to get a simple example of setting up a VPN S2S using certificates on an ASA
http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080aa5be1.shtml
I would try to separate your questions and see if I can answer. I will speak without using the SCEP Protocol because it adds a layer of complexity that can be confusing.
(Q) Comment can I get a certificate?
1 generate a RSA key pair. A pair of RSA keys as you indicate has a public and private key. Public and private keys are large number created by multiplying the other prime number (very simple explanation). These keys are used for encryption simple control. The private key is kept private and never awarded. The public key is provided for everyone through the certificate received from the device.
Data encrypted by the public key can only be decrypted by the private key and vice versa.
more details here: http://en.wikipedia.org/wiki/RSA
2. we create a trustpoint (container to configure and set parameters in the certificate). In the trustpoint that we associate the RSA key pair, give a name (usually the FQDN of the server that will present this certificate), configure if certificates that are authenticated by the trustpoint must also be checked in the LCR... etc.
3. then we can create CSR using the crypto ca enroll command. Now, we take this REA and provide it to Entrust. If this is done via the SCEP protocol you would have already done the next step of the authentication of the trustpoint.
4. When you receive a certificate from a third party, such as Entrust, they should also provide the certificate chain that allows the authentication of the certificate that they have signed all the way upward at the root (self-signed certificate server, the certificate must already be approved by most of the systems of operation/web-browsers). We want to install the string in the ASA because the ASA does not trust any certificate by default, it has an empty certificate store.
5. on the SAA, we now install the string provided by Entrust. Usually your identification certificate will be signed by an intermediate CA, just like the certificate of supportforums.cisco.com. Trustpoint ASA system for a CA (root or intermediate) and an ID (identity) by trustpoint. So we will probably have at least a trustpoint more.
Crypto ca trustpoint Entrust_ROOT
Terminal registration
output
authenticate the crypto ca trustpoint Entrust_ROOT
Don't forget to use trustpoint names who will lead them to you and your organization. Create a trustpoint for each of the CA certificates except for the signer of the certificate direct to your ID. Authenticate the signer directly in the trustpoint even where you install your certificate ID.
the import of crypto ca trustpoint ID certificate.
You should now have a fully usable authenticated certificate. PKCS12 import require a certificate to decrypt the private key that is stored in a PKCS12. But if you generate your CSR on the same device that when you install the certificate, then it would not need to export PKCS12 and a password.
---
A small side is not on the signature, a signature of certificate (fingerprint), also known as the name of a digital signature is a hash of the certificate encrypted with the signer's private key. As we know, whatever it is encrypted with a key only can be decrypted by the public key... all those who approves the signer's public key. So when you receive the certificate, and you already trust the signer, then 1) to decrypt the signature and 2) check that your certificate hash table corresponds to the decrypted hash... If the decrypted hash does not match then you do not trust the certificate.
For example, you can watch the certificate for supportforums.cisco.com,
The topic is: CN = supportforums.cisco.com
The subject of sender (signatory) is CN = Akamai subordinate CA 3
Akamai subordinate CA 3 is an intermediate certification authority. It is not self-signed
CN = Akamai subordinate CA 3 issuer is CN = GTE CyberTrust Global Root
CN = GTE CyberTrust Global Root is a certificate root (Self signed).
We would like to install this entire chain in the ASA so that we can provide this certificate and chain to any device and safely as long as this device trusts CN = GTE CyberTrust Global Root, then it should be able to verify the signatures of the intermediary and, finally, our certificate of identity of us trust.
---
Looking for another post to do a quick discussion about how the certificate is used in ISAKMP and IPSec.
Kind regards

Hello
The problem:
Our technology smart tunnel doesn't seem to be forward traffic to our new customer from the view. I wonder what kind of configuration changes must be considered to enable such a connection. The error returned when searching for the host name goes in the direction of the hostname not found. Error finding of intellectual property is related to the time-out.
Background information and specifications:
We are in the process of upgrading our servers from 5.2 to 6.2 connection. As part of the upgrade, we want to improve our customers for the Horizon to use version 3.5.0. To make it easier on vendors and remote computers we prefer also to our Horizon View Client with ThinApp 4.7.3 ThinApp. We currently have a Cisco ASA, supporting a SSL VPN portal with "Smart Tunnel" technology. The ASA is currently on firmware 9.3.3 in production, but we have access to version 9.5 in test.
Preferred connection scenario:
User > PC > VMware View Client (ThinApp would be) > Cisco ASA Smart Tunnel > view connection server > Virtual Office
.exe running on the client to view ThinApp:
It seems the ThinApp Client version view is only launching VMware - view.exe.
.exe running from the customer view full/thickness:
VMware - view.exe
-ftnlsv.exe
-vmwsprrdpwks.exe
-ftscanmgr.exe
There is something else to consider when the view client configuration ThinApp or thickness to work with Cisco SSL VPN Portal and the Smart Tunnel? We should have ports configured in the client in connection with the same view Firewall works with SSL VPN Portal port redirector functionality.
We have not been able to find any documentation on how to properly configure the smart to work with the New Horizon 3.5.2 client Tunnel. A ticket of troubleshooting with Cisco suggests that the Smart Tunnel feature still perhaps not compatible with this new Horizon (thin or thick) client. Currently, we are looking at other options because it is not not clear whether Cisco will be able to get us the confirmation or offer a solution without delay of our project to upgrade. Maybe stick to the previous VMware View Client version 5.4.0 which we know work with Smart Tunnel in some situations and with the redirector port for others.

Discover device directly connected to the cisco ASA
How do I know which is directly connected to an ASA interface? I'm looking for some commands that can be executed on the SAA to find the directly connected Cisco device.
Thank you
Boudou
Unfortunately it is not available on SAA for you tell what device is directly connected to it, there is no 'see the neighboring cdp' on SAA unfortunately.
You can check the ARP table and see which is the next hop, but who would only give the layer 3 device, such that there could be a switch between the two institutions.

Problem with the Cisco ASA 5525 X SFR and Firesight high school
Hi team,
We have two ASA 5525 X installed on them and Firesight in a Linux VM whose two SFRs are registered with SFR failover mode. We use the SAA secondary off the hook if the primary fails to turn on the secondary manually switch the wan cable. I turn on the ASA secondary every weekend to take the configuration of the primary for the ASA and the SFR and close by button walk / stop.
Last week I turn on high school ASA and the Firesight couldn't see the secondary SFR and show the message below:
Module device heartbeat: device
> don't send heartbeats. (I should mention I can Pinger the IP ADDRESS)
I tried to study the problem without success.
I also deleted the sensor just Firesight devices management in case something is stuck, and I'm trying to re added without success.
I'm new in firepower so... any ideas?
Thank you
Finally, this problem has been resolved by the redefinition of firepower:
see detailed here procedure to perform this redefinition;
http://www.Cisco.com/c/en/us/support/docs/security/ASA-firepower-service...
Before that, it appeared that firepower was not very healthy:
After a success "" configure Manager add xxxxx"command.
the command of managers show show nothing;
He should have shown this result:
> Display managers
Host: 193.193.2.75
Registration key: AZERTY
Inscription: pending
State of the PRC:on the other hand, in expert mode, the following command shows several processes (and not in the normal state):
sudo pmtool status | grep-i down
Last point,
After the recreation and reconfigure all this fire power, installed in the ASA secondary standby, was considered to be OK under Firesight health Monitor,.
but after 10mins, it appeared in critical condition with the following message:
"Interface"DataPlaneInterface0"receives not all packages.
This is normal and due to the fact that Eve ASA receives no flow and the same goes for firepower inside this ASA;
by performing a failover from the primary to the secondary ASA, this critical message disappeared for firepower inside the ASA Sec and appeared for firepower inside the ASA elementary school
-
A possible bug related to the Cisco ASA "show access-list"?
We had a strange problem in our configuration of ASA.

There is a comment in the running configuration: (line 26)
Inside_access_in access-list CM0000088 EXP:1/16/2014 OWN Note: IT_Security BZU:Network_Security JST:PortRange
This comment is missing in 'display the access-list '. In the access list, for all lines after this comment, the line number is more correct. This poses problems when trying to use the line number to insert a new rule.
Everyone knows about this problem before? Is this a known issue? I am happy to provide more information if necessary.
Thanks in advance.

The traffic load between the power of Cisco ASA and FireSight Management Center fire
Hi all
I have a stupid question to ask.
Can I know what is the traffic load and the e/s flow between firepower Cisco ASA and FireSight Management Center?
Currently working on a project, client require such information to adapt to their network. Tried to find in the document from Cisco, but no luck.
Maybe you all have no idea to provide.
It varies depending on the number of events reported from the module to the CSP. No event = only health controls and policy changes are exchanged. 10,000 events per second = much more traffic.
Generally it is not a heavy load, however.

The ACE IPS Cisco and Cisco ASA AIP - SSM (IPS)
Is there a difference between the features offered by the Cisco ACE IPS and Cisco ASA AIP - SSM (IPS) devices?
Can we do without Cisco ASA AIP - SSM (IPS) of 'only' configuration/implementation Cisco ACE IPS.
Cisco AVS/ACE emphasis on commissioning and to secure web-based applications. IP addresses do not focus on just the web applications and trying to get the multiple layers of the OSI stack. Consider the IPS as a general practitioner and the ACE/AVS as an eye surgeon, or something :)
Here is the response from Cisco itself:
Q: how is Cisco AVS Firewall application differs from an intrusion prevention system (IPS)?
A. IPSs are solid solutions of protection against targeted attacks of known vulnerabilities in major platforms such as Windows, Solaris, Apache or Microsoft Internet Information Services (IIS). Cisco AVS excels to protect against targeted attacks Web sites or enterprise applications. These applications can be built custom internal applications or software vendor. Signatures and security patches are generally not available for these types of applications, and building these security levels in each application, it would be almost impossible.
Q: how is Cisco AVS Firewall application differs by a network firewall?
A. The Cisco AVS 3120 and Firewall network such as the Firewall of Cisco PIX® and Cisco ASA 5500 Series Adaptive Security appliances are complementary products. The application Cisco AVS Firewall secures Web applications; excellent network in the network security firewall. and the Cisco AVS provides defense in depth for Web applications.
Firewall network apply policy networks, IP addresses and ports; they have a wide range of application for many different protocols layer features. The firewall can and will be deployed in many locations, including the edge, edge of the enterprise network, branch, etc. Cisco AVS imposed the policy on data HTTP as URL, headers and parameters. Cisco AVS is deployed in the data center in front of Web applications
