• Specific shell - ACS command authorization / GANYMEDE + on 2900XL

  Hello all-

  I was struggling with a particular issue here. I am running ACS 3.2 and tries to implement secure access to my switch. I have 'students' of my University I want to leave running specific functions, i.e. change the vlan port and write in memory, etc.

  I created with success the piece of the authorization, and my test account can connect. I have successfully assigned a privilege level of 7 also, that gives me a look of default base rights. Accountants strives also, indicating connections and commands me to come home.

  I want to do is use ACS to allow a particular group of controls, so I can change if needed in one place (ACS) and I not touch + 400 devices. ACS says can be done, but it doesn't seem to work. I created a Shell command group and specified commands, no luck. Even if I change the 'unmatched orders' rocking 'allow' (which should allow all orders, right?) it does not yet allow all orders. I added the Shell command group for the group, of which students are members...

  My AAA commands are as follows:

  AAA new-model

  AAA of default login authentication group local Ganymede +.

  Group AAA authorization exec default local Ganymede +.

  AAA authorization commands by default 7 Group Ganymede +.

  AAA accounting exec default start-stop Ganymede group.

  orders accounting AAA 7 by default start-stop Ganymede group.

  orders accounting AAA 15 by default start-stop Ganymede group.

  AAA accounting system default start-stop Ganymede group.

  Any ideas? Any thoughts?

  Thank you!

  Michael,

  You perform permission to order order that exist with a privilege level of 7. By default, the configuration commands have a privilege to 15. There are two ways you can go about solving this problem. The first would be to authorization of installation for level 15 command. The second would be to change the privilege level of the commands that you want your students to be able to run level 15 at level 7. This can be done with the command of privilege. Here is a link that shows the use of the technology locally within the unit. http://www.Cisco.com/warp/public/480/Priv.html

  I don't know if the ACS can push the configuration of the device on a per user basis, so the first option may be your best bet. Be sure to allow access to all controls for yourself.

• authorization GANYMEDE +.

  I can't control aaa authorization using win2k Ganymede +. I have the following commands on my router:

  AAA new-model

  AAA server Ganymede group + ciscosecure

  AAA authorization config-commands

  AAA authorization exec ciscosecure Ganymede group.

  AAA authorization network group Ganymede ciscosecure +.

  If the authentication that's good, I can even time of day login control. only permission issues, I need to define groups for users to belong

  Thank you

  Hello Francois,.

  You must add the following line/lines for authorization on the router-

  AAA authorization commands default Ganymede group 0 +.

  AAA authorization commands by default 1 group Ganymede +.

  AAA authorization commands by default 15 group Ganymede +.

• Failure of the authorization GANYMEDE + ASR1001

  Hello

  I use the below command structure identical to all other routers. However, when I try to type commands that it says "Authorization failed". The only difference between this routers and our other is a Cisco ASR1001. Is there as a special system requirements for this router that I'm missing?

  AAA authentication login default group GANYMEDE-local SERVERS

  AAA authorization exec default group GANYMEDE-local SERVERS

  AAA authorization commands 1 room of GANYMEDE-SERVERS in default group

  AAA authorization commands by default 15 GANYMEDE-SERVERS local group

  AAA accounting exec by default start-stop group GANYMEDE-SERVERS

  orders accounting AAA 1 group of market-judgment by default GANYMEDE-SERVERS

  AAA accounting group orders of 15 by default arrhythmic GANYMEDE-SERVERS

  AAA accounting connect by default start-stop group GANYMEDE-SERVERS

  AAA system by default start-stop accounting GANYMEDE-SERVERS group

  When you log in the router you authenticate with your GANYMEDE credentials or with the local credentials? I'm guessing it's the local credentials and that the router is not authenticate or authorize with the RADIUS server. If that is correct, you should investigate and find the cause of the failure to use GANYMEDE.

  I also suggest a change that may be useful. Change this line to

  AAA authorization commands by default 15 GANYMEDE-SERVERS local group

  TO

  default group 15 AAA authorization commands GANYMEDE-SERVER authenticated if

• Authentication/authorization GANYMEDE + based on the subnet of the user

  Hi guys/girls

  We have number of speeds of production, which are configured with Ganymede cisco + and all their work very well. But now I have an obligation to implement SSH-ver2 across the network, consist of about 8000 cisco gear.

  I need to develop a proof of concept (POC), that activate SSH to gears production will not affect Ganymede + existing and authorized user authentication.

  In our lab cisco gear, it was already configured with Ganymede + production for authentication and authorization server. Now, I am allowed to test SSH on these machines in the lab but I without disrupting other users who use the same laboratory-gears.

  So, I want to activate SSH version 2 on these machines in lab-however, when the user from a certain specific subnet, this user must be authenticated and authorized by the LABORATORY Ganymede +, but no production Ganymede +, however please note that lab-gears, that I'm testing with also already configured for production Ganymede + server as well. These devices in the laboratory must be able to do authentication and authorization of two different Ganymede + server based on subnet of users that he or she coming.

  Is - this plan is feasible? I am looking for documentation to implement the test of this method, is not successful.

  Your comments will be appreciated and evaluated.

  Thank you

  Rizwan James

  Adely,

  It won't work, the Ganymede authentication begins once the ssh connection is established, the n (router or switch) will open a Ganymede connection and send the start indicator to the RADIUS server in which the 'getusername' message is sent from the RADIUS server to the device and the user terminal. You cannot create an acl in order to choose which Ganymede servers you can authenticate either. When it comes to authenticate users from a specific subnet to a server specific RADIUS which is not the design of Ganymede, when you configure multiple servers in a group is to ensure high availability such that when a Ganymede server goes down you have a secondary school continue with authentication requests from the.

  Here is an example of how the RADIUS authentication is performed.

• Problem with shell command authorization

  I came across this issue with ACS 3.1 and 3.2 of the ACS

  A shell command authorization set is created under the profile shared with the following components:

  Unmatched orders: refuse

  Permit of unmatched Args: UNCHECKED

  The order authorized is 'show' with the Arg "worm permit", "allow the interface" and "allowed to run.

  This permission set is then applied to the group, under the option "Assign a Shell command authorization on any device on the network."

  Select this group option is set to 'Max privilege for any customer of AAA, level 15.

  This configuration is then tested against two IOS switches, with orders from aaa as follows:

  AAA new-model

  AAA authentication login default group Ganymede + local

  the AAA authentication enable default group Ganymede + activate

  AAA authorization exec default group Ganymede + local

  AAA authorization commands 15 default group Ganymede + local

  The problem I have is that when a user who is part of this group connects, it can issue commands such as see the worm, see the race and show int just as I would expect. Any command that does not begin with a show... is denied. However, other show commands that do not appear in the arguments of will work, so that some don't. For example, "show arp" and "vlan" worked, while "show accountants ' and 'buffer' does not. What Miss me?

  commands that work without explicitly set them are of privilege more low level 15... for example; "show arp" is a command of Priv-1, so it is execuatbel without permission of command as you do not permission to order for private-1.

  Current privilege level is 1

  It should work because it is a guest message.banner whenever you try to connect (console/vty). I set it up on my router.

  If you have banner motd, it will appear as well (see below). So, I have to remove it to get only the aaa banner & prompt is displayed:

  Now enter your password:

• Question of console GANYMEDE

  Hello

  I just put GANYMEDE on some IOS devices, I'm only using a default group that is configured to provide level 15 privileges. As I use the same default group on the vty and console I would expect access by 2 methods are the same, but when I telnet in I get 15 directly to the guest level of #, but when I console in I always get prompt for the secret to activate it.

  All ideas

  Concerning

  Chris Ayres

  Chris

  You can find a behavior that Cisco has done for a long time (and probably for good reason). The authentication/authorization GANYMEDE someone directly implement default privilege mode works on the vty and does not work on the console.

  The reasoning is that if you make a mistake in the configuration of the authentication/authorization (very easy to do - especially if your understanding of what you are doing is a little weak), it would be easy to lock you out of the unit. By default it works on vty and does not work on console (prividing far to recover from problems). There is a hidden command that allows you to also have it working on the console (be very careful that your config works correctly before you activate it on the console).

  If you want it, try this:

  authorization AAA console

  Thank you!

  I would like to clarify a few permission options.

  Activate the mode is priv 15.

  Because of the line "exec authorization default aaa group Ganymede +" router wil request ACS to check that the user has private level 15, no matter it's the fallback solution. Your options are:

  1 set the Group of users in ACS to access a shell and especially of level 15 privileges.

  2. change your router config "default aaa authorization exec no" this is however less sure and not recommended.

  You can take "enable default of enable aaa authentication ' out of the config because you use Ganymede +, because as I said, if you use the authorization Ganymede + it's going to always check with ACS for this level of 15 private.

  See the attachment for a view where you enter at this level. By default, only the group can be configured like this, but there is a way to apply it to a user - this can be done by checking this attribute via the "interface Configuration" - then "Ganymede" options.

  Hope this helps, let us know the results.

• ACS command authorization mode t conf report

  Hi, this is probably a quick, but I couldn't find a solution so far.

  We use authorization to order through ACS and are thus able to see (in the case of problems) which concluded the orders at that point on which device. But it doesn't work until someone goes into mode t conf. After that I get log entries in the ACS (Version 5). I can see all the orders and who entered the configuration mode, but nothing after that. Excerpt from the configuration:

  AAA new-model
  connection of AAA 5 authentication attempts
  enable AAA authentication login default group Ganymede + local line
  the AAA authentication enable default group Ganymede + activate
  AAA authorization exec default group Ganymede + local
  AAA authorization commands 1 default group Ganymede + local
  AAA authorization commands 15 default group Ganymede + local
  AAA accounting exec default start-stop Ganymede group.
  orders accounting AAA 1 by default start-stop Ganymede group.
  orders accounting AAA 15 by default start-stop Ganymede group.
  AAA - the id of the joint session

  My guess is that I'm hosting orders with that and so no permission is necessary.

  Any idea?

  Thank you

• ARP

  When "show arp" switch cisco, the arp table only contain the information on the neighbors of switch, but without guests, why?

  Eric

  Assuming that HostA and HostB are in the same subnet.

  Because the hostA will arp on the mac address of host b. If hostA broadcast on the local subnet syaing who owns this IP address IE. the IP address of host B.

  Host B repsonds with HostA mac address. The switch if it is a pure layer 2 switch only cares about the mac address and the port, he came above and it should save that it in the mac address table is.

  Do you mean that you do not see the mac address of the HostB in the mac address table?

  Keep in mind that entered mac address get timed in the cache switch.
