ACS Appliance - Advance filtering

Hi all
Quick question about my NAC setup on the ACS appliance.
I have create a number of Network Access Profiles from the templates that ACS provide. All is working fine but my question is in regards to the Advanced Filtering under the NAP.
When I created a template to support L2-802.1x users it placed the following attributes into my advance filter
[026/009/001]cisco-av-pair not-exist aaa:service
[006]Service-Type != 10
And when I created a template to support mac-auth-bypass it placed these following attributes into my advance filter
[026/009/001]cisco-av-pair not-exist aaa:service
[006]Service-Type = 10
What does the following line do?
[026/009/001]cisco-av-pair not:exist aaa:service
And what do these 2 lines do exactly.
[006]Service-Type != 10
[006]Service-Type = 10
Thanks
Dale

"cisco-av-pair not:exist aaa:service"
means to match, the incoming request must NOT include a cisco-av-pair VSA attribute that contains the value "aaa:service=........"
remembering that the cicso-av-pair is like a container for TACACS+ style attributes of the form "protocol:attr=value" eg "ip:addr=1.2.3.4"
RADIUS Service-Type 10 is "Framed Routing" which has been reused for some purpose by the NAC people. Not sure what it denotes but your filters are looking this attribute != (not equal to) and equal to this value.

ACS, NAP And Advanced Filtering

We have already implemented ACS applicance 4.1 integrated with AD.
But configuring NAP we faced the following problem - we want to use Advanved Filtering in NAP and filter users by users' membership in AD Security Groups.
are there any way to do it? if yes please tell me what attribute can be used for this.
Thank you,

If the NAP is configured with
1. A Network Access Filter with a specific network access filter (not any)
2. Advanced Filtering rule that states "User-name contains host/"
The NAP is not matched when machine authentication occurs.
If the NAP is configured with
1. A Network Access Filter with "any"
2. Advanced Filtering rule that states "User-name contains host/"
The NAP is matched when machine authentication occurs.
After ACS installation "advanced filtering" lists include just IETF attributes.
If you happen to use other vendors (known to ACS) like Ascend, then usially
we need:
= define AAA client with RADIUS(Ascend) as a dictionaly
= goto "Interface configuration" -> RADIUS(Ascend) and select attributes
which you are going to use in group profiles.
Above steps are enough for these additional atttibutes to be added
to "advanced filtering" list as well. This is how it is supposed to work.

RDBMS Synchronization problem in ACS Appliance 3.3

Hi,
I was adding multiple AAA Clients on ACS Appliance using RDBMS Synchronization option I followed the complete steps but failed to synchronize accountActions.csv file on ACS my ftp server is working fine and returned the logs saying "accountActions.csv file read recieved file successfully size 0 bytes 0.00 kbps" and RDBMS synchronization logs ACS reported as "No import CSV file on ftp server - nothing to process" I have attached related screen shots. Any help on this issue will be highly appreciated.
Thanks in advance
Best Regards,
Ahmed

The format of the accountsaction.csv file is incorrect as a result of which the RDBMS Synchronization is not executed correctly.
I have attached a sample accountsAction.csv file for you.
(i) The AAA Client C7609-X with the ip address 10.10.10.10 has been added with the shared secret key as mikey and is is registered with TACACS+
(ii) The NDG michasisX has been added.
(iii) The device C7609-X has been added to the NDG michasisX
Place the file in the FTP and try performing an RDBMS synchronization. Restart the ACS services.
Then you can add the devices as per the sample file attached.
Also check if the file name is exactly the same in the RDBMS Synchronization page in the ACS
Hope this helps,
Soumya

ACS appliance -- AD -- RSA Securid Server

I have Cisco ACS appliance running version 3.3.2.2 and Windows Active Directory on Win2000 Advanced Server and RSA v5.2. I already installed successfully the remote agent in Active directory.
Authentication using EAP-FAST from my wireless client going to ACS to AD is successful.
But when authenticating going to RSA failed. I can't find logs that my ACS is communicating successfully with RSA.
Here's more info:
In Active Directory, remote agent for ACS installed succesfully. Agent for RSA is also installed succesfully.
In ACS appliance, remote agent was already pointed to AD.
No RSA SecurID Token Server found in my External User Database Configuration list. I think this is the problem.
How can I manage to configure RSA SecurID Token Server in my ACS appliance?

Hello,
The configuration guideline for the ACS is described in "Configuring CiscoSecure ACS for Windows NT with ACE Server Authentication" at
http://www.cisco.com/en/US/products/sw/secursw/ps2086/products_configuration_example09186a0080094650.shtml
I had this up and running with a customer. There was no AD involved though, so it is not entirely your case and there might be other obstacles on the way.
ACS with ACE however works, though there were some nasty problems to be solved on the way to success.
One thing to point out straight away also mentioned in the document mabove:
Challenge Handshake Authentication Protocol (CHAP) cannot be used with the ACE tokens alone because of the requirement CHAP RFC (1994) that states:
CHAP requires that the secret be available in plaintext form. Irreversibly encrypted password databases commonly available cannot be used.
This precludes use of the ACE tokens for straight CHAP unless there is a separate CHAP password. For instance:
username: xxxx
password: xxxx
Password Authentication Protocol (PAP) is a better choice here.
This means the user has to enter "username*token" - the customer finally wrote a Java applet to construct the propper combination out of different clearly named input fields to simplify the input for unexperienced users.
Hope this helps! Please rate all posts.

No access to serial console in ACS appliance 111

We have 2 Cisco ACS appliances running version ...
Cisco Secure ACS 3.2.2.5
Appliance Management Software 3.2.2.5
Appliance Base Image 3.2.2.1
The fact is that after initial setup, we have never used the console mainly because in a production environment we manage them through the Web Admin application. Now we have decided to upgrade both appliances to the latest version (3.3.3) and when we tried to connect to the serial console (115200,N,8,1, no flow control) we don't get any response from none of both ACS. It's quiet strange but we have found no way to make them work. We have tried several things I expose to you in case you can give us any hint:
1. We have rebooted the appliance and we can see through the console all the start-up process but when it finally finishes the start-up, we see no login prompt.
2. We have also shutdown the appliance properly and power it off and on again. Same results. The appliances boot normal but still we don't have console access.
3. We have tried boot the appliance with the recovery CD-ROM and the console works fine. I can reset the Admin password, but when it restart from its own system ( I mean without the recovery CD_ROM), I can see all the starting messages but when it finish the start-up process ... no console access.
4. Finally I have connected a monitor and a keyboard to the appliance ( I know Cisco dosn not recommned it but when in trouble....) and I see the full start-up process and it includes the base Windows 2000 server operating system startup. When Windows finishes loading, we get a lock screen in which the appliance informs you that it have started correctly and that we could access it for management through the serial console port or through the web console. 10 seconds later I see a pop up window stating that on or more services have not started correctly and that we shoulkd check the Event viewer, something we wished we could do but as you you, this is a secured system and I don't know if there is a back door method to verify windows services in this appliance.
Any help would be appreciated, as the problem is identical in both the appliances and upgrading them without access to the admin console is difficult and risky.
Kind regards.

Hi
I had similair problem being locked out of console after initial configuration wizard.
I think there is a bug within the console session in that if you input a hostname of more than 15 characters, it locks up the ACS service when the server reboots. If you keep your hostname to less than 15 characters, the server reboots and you get console access. If you then access the GUI, you will see that 15 characters is the maximum, and you cannot enetr any more than this. This is not the case with the console, where you can enter more than 15 without getting an error message.
I rescued the server by doing F8 and rebooting server with last known good configuration. from there, you can reset the hostname to something valid. You can check to see which CS services are running through console session, and start any services that may not be running..

Adding a Custom VSA to a Group - ACS Appliance

Hi,
Using a secure ACS Appliance 4.0
I want to add a new RADIUS Vendor and its associated VSA to the ACS configuration. This will then be returned during Authorization.
I have already added the new Vendor and the required VSA through RDBMS. I can now see the new vendor as RADIUS (vendor) in NAP Profile etc
However I cannot seem to find a way that how would i set the Value of the Added VSA ? And assign it to a particular group ? I cannot seem to find that VSA anywhere.

Add a AAA client with "Authenticate using" Radius(vendor)
then go to Interface Configuration and enable VSA for Group/User

ACS appliance External Auth to NT 4.0

Hi
I am installing the ACS appliance to do external database authentication to NT 4.0 PDC. It appears with the appliance you have to install a remote agent to make this work. It is my understanding this agent must run on a win2k box. Does the agent have to be installed on the PDC or can it go on any windows server box?
Is there a work around if you do not have a win2k server. This network is still NT4 with now win2k boxes
Thanks

The remote agent was not tested on NT4 and probably wouldn't even install properly. Even if it did work, you would be very limited in the support you'd get if you had strange problems because it is an unsupported configuration.
It doesn't have to go on a PDC, but things just seem to work better if it is on a DC of some sort. At the very least it needs to be on a member server, but as I said, I'd recommend putting it on a BDC from experience.
The release notes/install guide for it is here:

New ACS appliance not showing FQDN hostname in GUI

I've installed two new ACS appliances in our environment running 5.3. I've just configured the basics to get it on the network (ie DNS, default GW, IP address). Looking at both running configs, they are identical with exception to the IP addresses. On one appliance in the GUI next to the user name in the top right hand corner, the hostname is "acs01". In the GUI on the other appliance, it shows "acs02.corp.mycompany.com". This is a minor issue but its bugging me. Anyone have an idea what is going on?
In both appliances, this statement is identical in the show run:
ip domain-name corp.mycompany.com

Hi,
So you are using a hardware RAID5 in storage pool as a hard disk. Now you added one more hard disk to the RAID5 with the tool "Dell Server Administrator" but it is not recognized in storage pool.
I think it will not work as hard disk size cannot be changed after storage pool is created. It is by default.
However why you use the hardware RAID in a storage pool? A hardware RAID seems enough for your storage requirement.

Apply patch to acs Appliance

I was wondering if someone can help me to upgrade my ACS Appliance with patch 4.1.1.23.4-SW. It was simple to apply this one in a normal server 2000. The ACS appliance I think is different because that we can access by normal terminal, keyboard and mouse.
Some were I read that is necessary a tomcat server?
Please help
adi

Hi,
ACS v4.1.1.23 patch 5 is available so go for this new patch.
You should have a pc which can access ACS through web interface. Keep the patch file on the PC.
Follow the steps below on the PC:
[1] Extract zipped file
[2] Look for ?autorun.exe? file and double click on it
[3] It will start a tomcat server on your desktop and you?ll see a web page asking for ACS
SE ip address :
Provide in the ACS SE ip address and press ?Install?
[4] It will prompt for ACS admin username and password as shown below :
Provide in the username and password and login.
[5] Then it bring up ACS GUI, then go to
System Configuration > Appliance Upgrade Status > Download,
Then we?ll get a screen where it will ask for ip address of Install Server :
Provide in ip address of system from where we are applying this patch, in our case our
desktop ip address, then click connect.
[6] It will show us following screen :
Click on ?Download Now?
Then it?ll show us this screen :
Press ?Refresh? Till we see following screen :
[7] Now press ?Apply Upgrade?. Then it?ll ask for confirmation :
Press ?Upgrade?, then we?ll get information regarding the patch.
Click ?Yes?.
It?ll take few minutes to apply that patch on appliance.
Then it?ll show us a confirmation message :
Press ?Done?, then system will reboot.
To confirm that patch has been applied successfully, goto
System Configuration > Appliance Upgrade Status
After everything is fine stop the tomcat server by clicking on ?stop distribution server? or
if you want to apply this patch on some more appliance click on ?Install Next?
Hope this helps.

Can a single ACS appliance be integrated with a diff OU in the AD (maybe with a diff IP address range).

Hello Everyone,
Can a single ACS appliance be integrated with a diff OU in the AD (maybe with a diff IP address range). If yes, how?
Thanks,
Rishi

Rishi,
Are you looking to leverage certain group in AD to be assigned to a specific subnet? If yes, then this can be done through dynamic vlan assignment.
Thanks,

ACS Appliance configuration issue.

When I attempt to configure the ACS IP address I am getting the following error:
"Error; Failed to get NIC configuration: <null> <FFFFFFFF>"
The device is connected to a working ethernet port and the the physical layers have been eliminated. Aside from starting from scratch, can anyone suggest a way out of this problem?

you need to reimage the ACS appliance.

ACS Windows vs ACS Appliance

I have ACS 3.3 running on Win2k and am looking to upgrade. Would it be a better idea to get the ACS appliance instead? What are the pros/cons?

Hi
Personally I wouldnt choose an appliance over software. Cost aside they are harder to integrate (esp if you use AD), harder to diagnose and patch.
From experience I know ACS sometimes needs a little TLC to keep it working. ACS v3/v4 was not designed as appliance software. This has been retro-fitted with all the issues that go with it.
ACS v5 is supposed to be appliance from day 1 so maybe that'll be ok!
This is my own personal view, Im sure there are a lot of happy appliance owners out there.
Main differences
1) Appliance cant talk direct to AD. You need to install an agent somewhere (possibly requiring a dedicated windows server.. ouch what happened to lower TCO!)
2) No native ODBC, RSA (done via RADIUS instead)
3) Logging. CSVs hard coded to rollover at 10MB. Requires log agent or extraxi csvsync to collect logs.
If you like to be "hands on" stick with s/w

ACS Appliance Upgrade

I obtained the 3.3 release from Cisco. I'm currently running v3.2. When I go to System Configuration -> Appliance Upgrade Status -> Download -> Connect -> Download Now, it returns "No Distribution in Appliance". I can see the 3.3.3.11 in the software install table. but it returns the error above when trying to transfer the file. I'm running Apache / Windows XP SP2. Anyone seen this before?

Hi,
Without Distribution server, normally you need to load the new image into the current ACS appliance itself before execute the upgrade process. The new image can be transferred via serial or ACS web-based 'system upgrade' option.
If I am not mistaken, the error you're getting was due to unavailability of distribution server.
If you stuck with the image transfer, try to use CLI/console mode.
Typicall upgrade method has 3 steps:
1. Load new image (download from Cisco or using CD) onto a distribution server.
2. Load the upgrade image onto the Cisco Secure ACS Appliance from the distribution server. Do it either from within the HTML interface, or from the serial console. The Cisco Secure ACS Appliance will verify the transferred files to ensure that they have not been corrupted.
3. Apply the Cisco Secure ACS Appliance system upgrade. You can do this either from within the HTML interface, or from the serial console.

Windows Update for Cisco ACS appliance

Due to the recent security alert from Windows I wish to make sure my systems are updated, but the cisco ACS appiance (cisco 1113) runs a specialized version of win2k with console access disabled. Is there any way get the windows critical security updates, and do I need to?

If the patch is necessary on acs appliance then they will be releasing it soon.
As of now we can't apply any windows patch on appliance.
