• NPS Windows Help for authentication of aaa for Cisco router - is it safe?

  I am very confused about how all this works and was hoping someone could help me.

  I followed a bunch of tutorials online for authentication RADIUS of installation on a Cisco router and he did to a NPS Windows Server. Now I can ssh into the router my AD account.

  Now that I got it to work, I go to the settings to make sure everything is secure.

  On my router, the config is pretty simple:

  aaa new-modelaaa group server radius WINDOWS_NPSserver-private 123.123.123.123 auth-port 1812 acct-port 1813 key mykeyaaa authentication login default local group WINDOWS_NPS
  
  ip domain-name MyDomcrypto key generate rsa
  
  (under vty and console)# login authentication default
  On the NPS Windows:
  I created a new RADIUS client for the router.
  Created a secret shared and specified Cisco as the name of the seller.
  Created a new strategy of network with my desired conditions.
  And now the frame of the configuration of the network policy that worries me:
  
  
  So initially I thought my AD credentials were being sent over the wire in plain text, but I did a capture and saw this:
  
  
  
  capture.jpg
  
          
      
  
  
  How is my password being encrypted and how strong is the encryption?
  
  Another thing is how can I configure aaa authentication with mschapv2? The documentation I saw for mschapv2 uses the "ppp authentication ms-chap-v2" command, but I'm not using ppp I'm using aaa with a radius server.
   
  			 
  Hello
  RADIUS encrypts the password, but sends the username in clear. GANYMEDE encrypts the user name and password.
  You can find the encryption used by RADIUS in the RFC scheme:
  https://Tools.ietf.org/html/rfc2865#page-27
  MS-Chap-V2 is used for the authentication of users such as the remote access and vpn, not management switch

• Cisco Nexus to use authentication Radius AAA using Microsoft 2008 NPS

  I have a Nexus 7010 running

  I was wondering if you can help me with something. I'm having a problem with the approval of the order through our aaa config. We have not an authentication problem of command approval that does not work. From what I've seen and read Nexus NX - OS 6.x has not all orders for the aaa authorization, unless you configure GANYMEDE +. My basic config is below if you can help would be much appreciated.

  > key RADIUS-server XXXXX

  > host X.X.X.X key radius server authentication XXXXX accountant

  Also nobody how to configure Microsoft 2008 NPS as Raduis server to work with Nexus? I read a few post that suggests to change the

  Shell: roles = "vdc-admin" in the value field of the attribute in the RADIUS server

  Anyone know if it works?

  Thank you

  I haven't used NPS before but sounds like you are on the right track. As Ed mentioned in his post, GBA, you can set the type of protocols that you will accept during an authentication session. Authentication Nexus sessions is considered as PAP/ASCII, so you should be good to go. I don't have a Nexus switch to test with, but if you can use wireshark to capture the session and see the exact protocol / method used. However, I am sure that PAP is the way to go:

  I need authentication radius configuration for Cisco IOS devices for device management. My radius server is on Windows 2008 R2.

  Can I implement this with encrypted authentication? In the attached diagram, can what protocol I use for encrypted authentication?

  According to some sites, we need activate authentication in clear text. All those put in place secure as MSCHAP authentication?

  Hello

  You activate the text authentication (PAP) clear. Don't forget Ray sends the username in clear but encrypts the password. You can confirm this take a wireshark capture. You will also get the RADIUS encryption using a key to Ray long and complex.

  If you want to encrypt the user name and password, then you would use GANYMEDE

• ISE server receives requests for authentication of the bridge VLAN, not the IP Address of the switch management

  Hello

  A 3850 catalyst switch has VLAN 20 (10.18.4.32/29) defined on it, which has a 10.18.4.38 gateway:

  D01-01-BWY #show ip short int vlan 20
  Interface IP-Address OK? Method State Protocol
  Vlan20 10.18.4.38 YES manual up up

  A server of ISE (SNS3415) is connected to a port configured on VLAN 20, with IP address of 10.18.4.33.

  01-BWY-D01 has to a management interface of 10.18.4.17.

  I created this switch as a device network in ISE and activated the RADIUS config and then configured the switch with the following commands:

  RADIUS attribute 6 sur-pour-login-auth server
  RADIUS attribute 6 support-multiple server
  Server RADIUS attribute 8 include-in-access-req

  radius of the IP source-interface GigabitEthernet1/0/1

  The problem:

  When I test the functionality of RADIUS using the following command, it fails. HOWEVER, the customer (switch) IP listed in the error log in the front door of the VLAN 20 (!):

  test the aaa group RADIUS server 10.18.4.33 auth-port 1812 Capita123 user radius acct-port 1813! new-code

  10.18.4.38 is the gateway IP address of the VLAN that hosts the servers of the ISE, I don't understand why its listed in error as IP device logs!

  Hello

  The only time I saw that it was due to use a deprecated command: radius server host.  There was a bug on the IOS XR platform as well.

  Could you please reconfigure your order of RADIUS by using the new command: radius server? And test again?

• Authentication RADIUS with ISE - a wrong IP address

  Hello

  We use ISE for radius authentication.  I have setup a new Cisco switch stack to one of our branches and set up the device network in ISE.  Unfortunately, in trying to authenticate, ISE logs show a lack of "Impossible to locate device network or Client AAA" the reason for this failure is that the log shows that it comes from a bad IP address.  The IP address of the switch is 10.xxx.aaa.241, but the logs show that it is 10.xxx.aaa.243.  I removed and added the configs of RADIUS on ISE and the switch, but it is always so que.243.  There is another switch battery location (same model, IOS etc), which works correctly.

  The config of RADIUS on the switch:

• No remote access after you activate the Radius AAA

  Hello

  I can't access our catalyst 4006 after activating the AAA for RADIUS. I have install IAS on our domain controller configuration / a catalyst as a Radius client and configured a remote access policy that points to an ad group to allow access to the switch. When I try to connect to catalyst by my user information in AD, it seems to crash after I type my password, asks for the password again, then says access denied. This happens both on the console and through a telnet session. I have included below the configuration of my AAA.

  I think that the immediate problem is that the source address of your switch ussed is not address who is pregnant with Ray. The Radius Server is 10.100.182.250 and it is in the subnet of the interface vlan 182. If the address of the interface vlan 182 will be the source address of the Radius request. Difficulty which is to use the command of source ip range address and specify the address at which you want the switch to be used. Of course, in the short term, it would be easier to change the Radius Server to wait 10.100.182.2 as the address of the customer.

• Authentication RADIUS on NX - OS (6.2) using MS NPS

  Hi guys,.

  I'm having a RADIUS configuration of wireless authentication trouble on NX-OS using Microsoft NPS.

  The error message that I am on the NPS server is:

   A RADIUS message was received from RADIUS client (10.10.10.2) with an invalid authenticator. This is typically caused by mismatched shared secrets. Verify the configuration of the shared secret for the RADIUS client in the Network Policy Server snap-in and the configuration of the network access server. 

  Nexus device, I learned that the recorded message:

   2015 Aug 9 07:49:47.595 switch1 %RADIUS-3-RADIUS_ERROR_MESSAGE: RADIUS server 172.16.88.166 failed to respond even after all retries 2015 Aug 9 07:49:47.595 switch1 %RADIUS-3-RADIUS_ERROR_MESSAGE: All RADIUS servers failed to respond after retries. 2015 Aug 9 07:52:00.234 switch1 %RADIUS-3-RADIUS_ERROR_MESSAGE: packet from RADIUS server 172.16.88.166 fails verification: The shared secret is probably incorrect.

  Although the reason for the failure is obvious, I am 100% sure that the shared secret is correct. I also tried to change about 5 times, but the result was the same...

  That's what I configured on NX

   aaa authentication login default group radius aaa authentication login invalid-username-log aaa authentication login error-enable radius-server timeout 5 radius-server retransmit 1 radius-server deadtime 0 radius-server host 172.16.88.166 key 7 "xxxxxxxxxx" auth-port 1645 acct-port 1646 authentication aaa group server radius radius server 172.16.88.166 deadtime 0 use-vrf management source-interface mgmt0 ip radius source-interface mgmt0

  One out more troubleshooting

   # show radius-server statistics 172.16.88.166 Server is not monitored Authentication Statistics failed transactions: 4 sucessfull transactions: 0 requests sent: 4 requests timed out: 0 responses with no matching requests: 0 responses not processed: 4 responses containing errors: 0

  I also configured the ASB for NX-OS on the network POLICY Server (shell: roles * "network-admin vdc-admin"), but I don't think he's going even at this stage (as it says the RADIUS server is a failure, not the user/references).

  All thoughts are more than welcome!

  Hello

  It is indeed a problem with the shared secret key. Try using a simple shared secret key (alphanumeric) and for Nexus while configuring a shared secret key, use key 0 to instead of the 7 button when entering the shared secret key.

  Link OS automatically convert the plain text in encrypted key (type 7) key.

  Yes, PAP always use text gross, and that doesn't provide any kind of security.  However, does not support administrative session with Ray chap/mschap.we cannot configure firewall/IOS devices for the Administration as a telnet/ssh session to authenticate users on the mschapv2 authentication method.

  If you need secure communications you can implement GANYMEDE.

  GANYMEDE + and RADIUS using a shared secret key for encryption for communications between the client and the server. RADIUS encrypts the password of the user when the client makes a request to the server. This encryption prevents a person from sniffing the password of the user using a packet Analyzer. However, other information such as username and the services being performed can be analyzed. GANYMEDE + does not encrypt only the entire load at the communication, but it also encrypts the password between the client and the server. This makes it harder to decipher the information on the communication between the client and the server. GANYMEDE + uses the MD5 hash in its algorithm of encryption function and decryption.

• Backup AAA for PIX

  I have a PIX with the following configuration:

  GANYMEDE + Protocol Ganymede + AAA-server

  AAA-server GANYMEDE + (inside) host 192.168.1.1 77777 timeout 5

  RADIUS Protocol RADIUS AAA server

  AAA-RADIUS (inside) host 192.168.1.1 Server 77777 timeout 10

  AAA-server local LOCAL Protocol

  AAA authentication GANYMEDE serial console +.

  AAA authentication enable console GANYMEDE +.

  order of AAA for authorization GANYMEDE +.

  AAA accounting correspond to aaa_acl inside RADIUS

  Everything works fine when the RADIUS server is available. When he is not available, I can log in with the username "PIX" and "password". The problem is, once I connected, I can't get permission to execute orders. Does anyone know of a command that is similar to the "if-certified" for routers that I can use?

  There is no method of backup for authorization for the PIX. As you know, if the RADIUS server is down, you can connect with "pix" and the password enable, but it doesn't help a permission. The only thing you can do is wait the GANYMEDE server back to the top. I'm sorry.

• ISE comments Portal failover for new applications

  I have a controller and resilience, not ability on both nodes of the ISE 1.2 (primary and secondary).  Each node of ISE has a management interface and an interface for the portal.  PSN is active on both nodes.  The WLC chooses the ISE node (with relief) for authentication.  Guest authentication, the user should be redirected to one of the two comments. What is the best method to choose and correctly redirect the user comments portal (including when it is down).  Is there a single other solution than a LoadBalancer for this scenario. Node groups are waiting for sessions and I need a solution for new sessions.

  Thank you.

  You don't need to do, once the WLC held a PSN down, new mab requests are sent to the next psn in your list of RADIUS on the wlc and other psn will respond with its own host name in the url redirect.

• AAA for VPN - Kerberos, LDAP or an NT domain?

  All,

  After that a small return on what you think is the best method for AAA authentication for VPN clients when authenticating against a Windows domain for remote access?

  I have always used "NT Domain" because it seems to correspond roughly to the NT Auth I used to use on the old hubs. However, I (finally) decided to take a look at the Kerberos and LDAP, since they must have been added for a reason...

  Far as I can tell LDAP adds the ability to search a little more finely (basic DN) AD, but that's all. Am I missing something? Are there more reason to use LDAP or Kerberos domain auth?

  What is more reliable? That you guys use?

  See you soon!

  Either it is reliable, you can map users in different group policies or apply different DAP political, based on their belonging to a group. If you are basic authentication, then your method is still the best way to go.

  Thank you
