• SSH Authentication: PIX-> RADIUS

  Hello. I try to have a [6.3.5] PIX firewall question a RADIUS server for authentication SSH users. The PIX is remote, if I'm afraid of losing access to it. :) My question is what commands can I enter if I am already SSHed in unity, such that the NEXT time I SSH in, PIX will check the RADIUS box for my user name / password challenge? Pleae help... Thank you!!!

  Hey Quentin,

  We can have this command, but it is not mandatory to have access SSH for the PIX.

  This command is used to verify the credentials allow RADIUS.

• Digest Access authentication

  Hello dear developers.

  Everything we've faced in a Digest Access authentication?

  I have a sript to server that allow to send me there an any files, a file store. It works perfectly with Android client. Now, I need to implement this type of functionality using AIR on the PlayBook.

  I have not found a native way to solve my task, then I begin to set up my own.

  According to the documentation to

  http://en.Wikipedia.org/wiki/Digest_access_authentication

  I send a request to the server using simple script:

  var request:URLRequest = new URLRequest(SERVER_URL);
  request.authenticate = false;
  request.method = URLRequestMethod.POST;
  
  var urlLoader:URLLoader = new URLLoader();
  urlLoader.addEventListener(HTTPStatusEvent.HTTP_RESPONSE_STATUS, httpResponseStatusHandler);
  urlLoader.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
  urlLoader.addEventListener(Event.COMPLETE, complateHandler);
  urlLoader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
  urlLoader.load(request);
  

  and get the necessary 401 error but without any information that I need to create a header for the next request, such as:

  WWW-Authenticate: Digest realm="[email protected]",
                    qop="auth,auth-int",
                    nonce="dcd98b7102dd2f0e8b11d0f600bfb0c093",
                    opaque="5ccc069c403ebaf9f0171e9517f40e41"
  

  Have experience with digest authentication?

  Thanks in advance.

  Yuriy.

  I found a solution to the question.

  First of all I would like to answer on '-> authenticate URLRequest' property. It is set to 'false' for one simple reason - the application is already allowed in the service to upload files to the server, it is strictly forbidden "by design" application architecture to have 'Auth' pop window whenever the user needs to download files on the server.

  So, we set this property to false.

  Then, back to the code, I was on the right track. What I have done is to use:

  urlLoader.addEventListener(HTTPStatusEvent.HTTP_RESPONSE_STATUS, httpResponseStatusHandler);
  

  to get:

  event.responseHeaders
  

  So it looks like:

  private function httpResponseStatusHandler(event:HTTPStatusEvent):void {
              var array:Array = event.responseHeaders;
  }
  

  The analysis of each element of the array, I can get a data that I need to use for the next stage of the authorization:

  Request Header name: WWW-Authenticate, value: Digest realm="MyRealm", nonce="l2iaxyy2BAA=d1f22aa7378131c0b1481ae68084e40559e21973", algorithm=MD5, qop="auth"
  

  So, there it is, now we have all we need Digest auth.

  More information on Digest authentication you can find here:

• AnyConnect authentication with RADIUS secure method

  I was able to correctly configure Cisco AnyConnect VPN on ASA 5520 with code 8.4.  I put it to authenticate to the RADIUS (Microsoft Windows 2008 Server NPS server) server.  I noticed something on the server under "constraints and the method of authentication.  I chose MS-CHAP-v2, but it is considered less secure authentication methods.  I can click on Add and choose other methods of authentication such as smart card or other certificate, PEAP, EAP-MSCHAP VERSION 2.  I chose PEAP, but then the VPN does not work.

  So first of all is it really important if I just leave it to MS-CHAP-v2?  Because from my understanding is that AnyConnect authenticate with the ASA and then ASA in the backend communicates with the RADIUS server to security point of this scenario should - not be enough as no UN encrypted or secure less information is available to the outside world?

  Secondly there is a documentation on the use of PEAP with Cisco AnyConnect?

  AnyConnect supports EAP-GTC, EAP-MD5 and EAP-MSCHAPV2.

  From the safety point of view, it does not matter much what you use as IKE still will be encrypt traffic between the client and the head of the line.

  Between the head and the RADIUS, the password is encrypted as well.

  From a to z, you good to go.

  See you soon,.

• View 5.1.1 without box of remote access authentication

  I have started to notice a problem since upgrade to view 5.1.1 when some users try to access their vm while working remotely via the Security Server Internet connection they initially get the error failed to connect as the current user, which is normal, but once you click ok, you should get a popup dialog box for entering your credentials authentication , but they're not getting it. With a user that I tested, I ended up retarting to the Security Server and it worked normally, but now the problem is back... anyone had seen this before? I don't see anything in the events of the view administrator, and I am search in the logs on the Security server but have not spotted something again.

  Uninstall the client of the view and remove the feature of saying things to open a session as the current user.  To my knowledge that they were not being updated much on view in the 5.1.1 client release.  If it does not try to use a 5.0 client view.

• 802. 1 x authentication with Radius and win7 Mab

  Good afternoon!

  I have a question about 802.1 x I've set up a laboratory in which I have configured authentication mab with 802. 1 x, but I have a weird behavior of my network controller. On the switch (4948e), I see that the user is authenticated and authorized, and I can see my switch these outputs:

  21 April 15:13:30.263: % AUTHMGR-5-START: start "mab" for the customer (a01d.48ac.b7f

  1d.48AC.B7F5) on the Interface item in gi1/11 AuditSessionID C0A8DF9C0000002E002F3DAC

  If I type "see the authentication session", the corresponding output.

  Switch #show authentication sessions

  Interface MAC address method ID of Session of field status
  Item in gi1/11 a01d.48ac.b7f5 mab DATA Authz success C0A8DF9C0000002E002F3DAC

  The thing is that when I check my network controller, it said "authentication failure". That's what I've done so far:

  1. I restarted my pc, the same behavior.

  2. I disabled and enabled my network controller, the same behavior.

  3. I rebooted the switch and re-configured. Same behavior.

  4. I tried with another PC configuration. Same behavior.

  5. I changed the configuration of "user authentication" using dot1x EAP authenticator and it worked.

  This is the configuration I have on my switch:

  AAA new-model
  Group AAA dot1x default authentication RADIUS
  Group AAA authorization network default RADIUS
  start-stop radius group AAA accounting dot1x default
  AAA - the id of the joint session

  !

  control-dot1x system-auth

  !

  Switch #show run gigabitEthernet int 1/11
  Building configuration...

  Current configuration: 128 bytes
  !
  interface GigabitEthernet1/11

  Cx-to-Host description
  switchport access vlan 223
  switchport mode access
  Auto control of the port of authentication
  MAB
  end

  This is the first time I'll put up a configuration 802. 1 x. I'm doing something wrong?

  I really hope that I am not the only one with this kind of behavior!

  Thank you for any assistance you can give me!

  Status: Authz success

  This means that the port is open. Is this permanent? Keep looking at the output of the show a few minutes see if it tries to dot1x too. Can you ping from the PC?

  As authentication of 802. 1 X is enabled in the properties of the map NETWORK PC that you can expect dot1x method runs on the switch and eventually respond to the computer with auth fail. Authentication in the PC box is not necessary for MAB.

  What type of RADIUS server you use and there 802.1 policy X in addition to MAB policy?

  IP address: unknown

  This means that the switch did not recognize the IP address of the host, probably due to the lack of

  analysis of IP device

  command. But it is not necessary for the plain MAB or dot1x.

• Several points of access Cisco Aironet 1131AG and same SSID?

  We have several Cisco Aironet 1131AG, all wired devices on a switch (2560) Cisco L2 which is connected to the L3 switch (3550). We have assigned a VLAN for access point to the L3 switch which acts as a vtp Server (L2 switch is vtp client). All the ap will have a static ip address and all will have the same SSID and no security, and they will use several channels (e.g. 1,6,11).  They will work in 3 floors for a roaming wireless client. We not using any wireless controller.

  So my question is this: how to configure the same APs-all with a different ip address, can we use L3 switch to create the dhcp server to access points VLAN (pool for guests) and the rest of the static ip address for the ap? One of the ap can be WDS and on the same radius server local time with users without Cisco Secure ACS or similar controller or I did not understand this very well :-). I followed the guide http://www.cisco.com/en/US/docs/wireless/access_point/12.3_2_JA/configuration/guide/s32roamg.html for WDS where Abu Cisco ACS part is a problem, so I can use the same ap as a Local authenticator as a guide http://www.cisco.com/en/US/docs/wireless/access_point/12.3_4_JA/configuration/guide/s34local.html#wp1035723.

  Thank you very much...

  Well, just so you know, WDS, and local RADIUS authentication is necessary only if you use authentication on your wireless connection.  You say that you do not plan to use security, so it's not necessary.  However, I highly recommend at least using a simple WPA2-PSK to lock your connection, otherwise you might end up giving free Internet access at best and at worst you could give access to the computers and corporate servers.  If you want to reuse a 802. 1 x or WPA authentication method, then Yes, you can use an AP as RADIUS and to improve WDS Server authenticated to roaming, but this is much more limited than the use of a Cisco ACS.

  As for your other questions, Yes, your APs can all be configured the same except for at least three settings: IP address, hostname, and channel.  Configure your static IP addresses on the interface of the PA BVI1.  Do not place it on the Radio or Ethernet interfaces, because if one of these interfaces goes down, you lose the ability to configure the AP, so it's best to use the BVI1 interface.

  And Yes, configure a DHCP scope for your customers on your L3 switch is good design, or you can also use your DHCP server on a different subnet by using the command of support-ip address on the interface of L3.  I hope this helps!  Let me know if you need help to set all this up.

  Merry Christmas!

• Newbie question on access to the RADIUS server

  I've worked before on RADIUS servers running on Windows but not on Unix. I'm new to an environment without any documentation and I make sure I have access to the GANYMEDE/ACS config.

  I go to my config switch and I see that ' 10.0.0.1 radius-server.

  Then I ssh into ' 10.0.0.1' and I see the below after "method.

  From the bottom, you have an idea on how to access the configuration of the ACS in case I need to change any setting it? I tried http://10.0.0.1 but it does not work.

• A problem when authentication via Radius ASA

  Hi all

  Please give me a helping hand. I have a problem when through ASA 5520 via Radius Authentication for ACS 4.0 via the VPN device. I need to configure secure authentication and NAC for remote user VPN. It simply does not work, but it works when you use Ganymede so all the connection seems to be ok as ACS succesfully authenticate a remote via MS AD VPN user when you use Ganymede. But I read that I can not use NAC when Ganymede using, I'm good? ASA and ACS journals indicate a problem with the shared key but I already double checked the key on both sides, the IP address is correct on SAA and I also tried all possible methods of RADIUS on SAA. Any idea where might be a problem?

  Hello

  When you use ACS 4.0, then make sure that the AAA Client for ASA entry you created on GBA, if under a NDG, then make sure that there is no key to the NDG level.

  Otherwise, pass entry client ASA as RADIUS ACS in NDG (Unassigned) on ACS.

  Kind regards

• Centralized authentication (IAS/Radius) in IDS/IPS 4260

  All,

  I was in charge of configuring authentication centralized via IAS for all IPS/IDS devices in the enterprise.  After much invest I'm pretty sure that my goal is not available due to the limitations of the device.  However, I'm still not sure at 100%.  My questions are:

  1 is anyone can provide a link or any documentation showing permanently the IPS 4260 supports Radius IAS authentication?

  a. If no, what would be a suitable alternative? CSM, etc.. ?

  Cisco IPS sensors do not currently support authenticated access to the outside.  They can't stand

  assignment of authentication and the role of user/password local name.

• ISE Sponsor authentication via RADIUS

  My client demand change us the way the sponsor users are authenticated and authorized to access portal Sponsor of ISE.

  Their similar to the request of the ISE AD via a RADIUS server first. They said "avoid sending credentials of the AD to ISE directly. Under this condition,.

  My research and limited knowledge give to assume I have to define a RADIUS Proxy

  I think I can define an external RADIUS server, but I wonder if this creation, it would be available as a Source of identity for "portal Sponsor sequence.

  If this is not the case, how can I add this? After that, what conditions or attributes should I look for to use in the 'strategy of group sponsor' in order to filter the name of user and password and allow access to employees and deny access to everyone?

  I'd appreciate advice that you can give me to offer the best recommendation to the client.

  Kind regards.

  Daniel Escalante.

  Hi sliman,.

  Unfortunately, this document is not relevant to what Daniel is trying to achieve.  There need to be able to refer to a RADIUS server as part of the Sponsor authentication process, that is not possible today.  The only possibilities are that I have indicated in my original answer.

• Authentication via Radius VPN

  I wonder if anyone has experience due to error.

  I have cisco ASA firewall, I configure AAA authentication to my Active Directory server. In my Active Directory server, I set up my ASA firewall as my Radius client.

  For authentication user my VPN, I set up my VPN user to authenticate through Active Directory server.

  In my Active Directory server, I have several groups. Some users are ABC GROUP, most of the users are in GROUP-XYZ.

  Users who are members of the ABC GROUP can connect successfully.

  Users who are members of the GROUP-XYZ cannot connect, keep Cisco VPN client to invite users to authenticate.

  ASA firewall gives error: load error processing useful: payload ID: 14

  When I add the user to become a member of the ABC GROUP, the user is able to connect successfully.

  Cisco ASA firewall, I see not all configurations that associate on behalf of Active Directory group.

  Hello

  Check the output of radius aaa/debugging debugging on the SAA for clues.

  I guess you are using NPS Microsoft, search newspapers all index.

  My assumption (a wild guess): check on your Active Directory directory group policies, check the 'grant dial in' setting and next to her another similar setting (I forgot the details, if there is more than one year, when I finally saw him), compare with NPS documentation and compare the two groups (pass/fail).

  Also check your policies for authentication on the network POLICY server if you have more than one.

  Hope that helps,

• Several statement list Access NAT (DMZ) 0

  Hello

  IM I have problems with remote VPN. The scenario is as follows:

  I have I have few clients who will connect remotely via VPN. Until today, one of them needed to enter my DMZ. But now I want a different profile (the cause is a new client) to access one of my server in the DMZ.

  So I said all of the VPN, the ACL settings, but when I want to declare the nat 2 access-list newclient (dmz) it does not work. But if I declare the nat 0 access-list newclient (dmz), it works, BUT it removes the previous 0 having my other client nat. Is there a way to create several access list statement 0 - nat (dmz)?. If this is not the case, how could I solve this problem?

  André,

  You can have as a NAT exempt list of access by interface (nat rule 0).  I understand what you are trying to accomplish.  You use the vpnashi and vpnlati access list to control access to devices for different customers through VPN group policies.

  What I do is the following:

  Create an ACL for the VPN client (that you have, with vpnashi and vpnlati)
  Create an ACL for NAT exemption for the interface (inside sheep, sheep-dmz, etc.).

  Create the ACEs within the exempt ACL of NAT that corresponds to your VPN client access-list.

  It is allowed to have multiple statements within a NAT exempt list to access.  This will not have a client VPN access to things, it shouldn't.

  For example:

  access-list sheep-dmz allowed extended host ip 192.168.16.28 192.168.125.0 255.255.255.0

  192.168.125.0 IP Access-list extended dmz sheep 255.255.255.0 allow host 192.168.16.28

  NAT 0 access-list sheep-dmz (dmz)
