• 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.

  Router > sh priv

  Current privilege level is 1

• Shell command authorization

  Hi all

  I'm having a problem with the Shell command authorization. I have a user that I just want to be able to display the configuration of installation, it is for the auto config to archives on an hourly basis.

  I have configuered the device with the following orders of aaa:

  AAA new-model

  AAA group Ganymede Server + ACS

  AAA authentication login default group ACS

  /NOAUTH AAA authentication login no

  AAA authorization config-commands

  AAA authorization exec default group Ganymede + group ACS

  /NOAUTH AAA authorization exec no

  AAA authorization commands 15 default ACS group

  AAA authorization commands 15 /NOAUTH no

  AAA accounting command 15 arrhythmic default group ACS

  The static account I have set up ok logs and can show config etc. Access to the conf t is disabled, which is good, but for some reason, it can run any command show rather than just who is this all I welcomed in the Shell command authorization.

  Unmatched command is defined for refuse and allowed unparalleled arguments are not checked.

  ACS is 3.3 2 and switch I tested running 12.1 (9) EA1

  Any ideas?

  Most of 'show' command are level 1 controls. You can check this by logging in as a normal user, issue a private "sho" to make sure that you are at level 1, and then type 'sho ip road', "sho ver", etc., you will see that all work fine.

  Your AAA commands say only the switch to allow level 15 commands, so when you do a "sho ver" or similar this order will not be sent offshore to the ACS server for authorization.

  If you add the following:

  AAA authorization commands 1 default ACS group

  so, what do you have to fix, but be careful because it is easy to lock you out of power mode enable (add 'enable' in your command set too).

  You should also noticed all those who 'show' commands were not their statement in detail either, because you have enabled also only accounting for level 15 commands.

• How to activate 'Shell command authorization games '.

  Hello

  I use aaa on Ganymede to check the user to active directory ms.

  I set up a new "Set Shell command authorization" see the attachment for more details.

  But it does not work. So, I just want to check if the use of a command works or not.

  You can see in the file attached, I tried something with the command 'show '.

  But if I connect I am still able to use "view aaa servers" example, but in the 'show' commandbox I asked the agrument "refuse the aaa" inside.

  Why doesn't this work?

  Thanks for the help

  BB

  BB,

  Not sure why you want to do it this way. Trick here is to give all users a priv 15 and then set the permission command, defined according to your need.

  Overlooking priv 15 does not mean that the user will be able to run all the commands. You can set permission set and allow that you want specific orders, the user should be able to run.

  So pls rate this help

  Kind regards

• Arguments using Wild-Card in Shell command authorization

  The Shell permission command Set allows the use of wild-card?

  For example, according to command shell permission, what can I put the arguments if I want to enable the command show interface fastethernet 0/1-24 run?

  And also, what should I put in as argument for a ip address if I want to allow "ping x.x.x.x"?

  Thanks in advance.

  Hello

  There are two wildcard characters used under authority of command Shell is the first ' ^ ' sign which designates anything that comes after this is accepted and the second wildcard is ' $' which means anything that is before. In your case, you can use

  Interface FastEthernet 0 1 ^

  and

  Ping ^.

  These commands allow access each Fastethernet and ping to an IP address.

  Hello world

  I'm trying to set up a shell commnds set orders (including t conf mode) will be allowed, with the exception of administrative commands, such as writing, copy, admin, format etc.

• Command authorization Config 3.3 ACS

  Hello

  I want to allow a user only add/remove the roads on a router. The shell command authorization works very well. But when the user is in configuration mode, it can start with any order!

  Debugging says:

  1w2d: AAA/AUTHOR: authorization config command not enabled

  How can I activate this and how/where can I he set up the GBA?

  Thanks in advance

  GBA just allow the user to enter the command 'road' as if you have any other shell command that they are authorized to do.

  On the router/NAS, you must tell him specifically that you want authorization for config commands with the following:

  AAA authorization config-commands

  Note that the format of this command changes slightly on different versions of IOS, but if you "aaa authorization?", you will be able to understand.

• Permission of AAA with ACS Shell-games

  Hi all

  I use a router cisco 871 running that version 12.4 (11) T advanced IP Services.

  I have difficulty getting permission to AAA to work properly with ACS.

  I am able to configure ACS fine users and assign them shell and private level 7.

  I then install a set of Shell Auth and enter the issuance of orders and configure.

  When I log in as a user, I get an exec with a level of 7 priv no problem, but I never seem to be able to

  to access global configuration mode by typing in conf (or set up) terminal or t.

  If I type con? It is the only command connect, configure is never an option...

  The only way I can get this to work is by entering the command:

  privilege exec level 7 Configure terminal

  I thought the whole purpose of the ACS Shell Set to provide this information to the router?

  It's frustrating

  The ACS server is set up with the Shell Set named Level_7 order authorization

  It is attributed to the relevant groups and I have the 'Unmatched orders' option selected in the 'license '.

  The "unmatched Args allowed" is also selected.

  See an extract of my IOS config below:

  AAA new-model

  !

  !

  AAA group Ganymede Server + ACS

  Server 10.90.0.11

  !

  AAA authentication login default group local ACS

  AAA authorization exec default group ACS

  AAA authorization commands 7 by default local ACS group

  !

  Cisco radius-server host 10.90.0.11 keys

  !

  !

  privilege exec level 7 Configure terminal

  privilege exec level 7 set up

  privilege exec level 7 show running-config

  privileges exec level 7 show

  !

  Hope you can help me with this one...

  PS I tried with orders of privilege on the router and remove the router and just keep getting the same results!

  Hello

  So now,

  You're actually using two different options and trying to couple then together. What I would say is you either use authorization Command Shell function or play with level privileges. Not mixed together both.

  Above scenario might work, if you move orders to focus on level 6 and give the 7 user privilege level. He couldn't be sure. Try it and share the results.

  That's what I suggest that orders back to a normal level.

  Provided below are the steps to set up the shell command authorization:

  -------------------------------------------

  Follow these steps on the router:

  -------------------------------------------

  ! - is the desired username

  ! - is the password

  ! create - us a local user name and password

  ! - in case we are not able to get authenticated via

  ! - our Ganymede server +. To provide a backdoor.

  password username 15 privilege

  ! - To apply the aaa on the router model

  AAA new-model

  ! - Following command is to specify our ACS

  ! - location of the server, where is the

  ! - ip address of the ACS server. And

  ! - is the key which must be the same during the FAC and the router.

  radius-server host key

  ! - To get the authentication of users through ACS, when they try to log - in

  ! - If our router is unable to join the ACS, we will use

  ! - our local user name & the password that we created above. This

  ! - we prevent locking.

  AAA authentication login default group Ganymede + local

  AAA authorization exec default group Ganymede + local

  AAA authorization config-commands

  AAA authorization commands 0 default group Ganymede + local

  AAA authorization commands 1 default group Ganymede + local

  AAA authorization commands 15 default group Ganymede + local

  ! - Sequence of commands are for posting to the activity of the user.

  ! - When the user connects to the device.

  AAA accounting exec default start-stop Ganymede group.

  AAA accounting system default start-stop Ganymede group.

  orders accounting AAA 0 arrhythmic default group Ganymede +.

  orders accounting AAA 1 by default start-stop Ganymede group.

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

  --------------------

  ACS configuration

  --------------------

  [1] Goto 'Profile components shared' a-> 'Shell command authorization sets'-> 'Add '.

  Provide any name at all.

  provide sufficient description (if necessary)

  (a) for full administrative access set.

  In the unmatched controls, select 'allow '.

  (b) for all access limited.

  In the unmatched controls, select "decline."

  And in the field above 'Add a command' box, type in the box below and the main command "permit unmatched Args" Order under allow.

  For example: If we want the user to only have access to the following commads:

  opening of session

  Logout

  output

  Enable

  Disable

  Show

  Then, the configuration should be:

  -----------------------------------------------

  -Allowed unparalleled Args.

  -----------------------------------------------

  connection permit

  permit disconnection

  exit permits

  Select the permit

  disable the permit

  license terminal configuration

  ethernet interface license

  permits 0

  to see the running-config

  ------------------------------------------------

  in example above, user will be allowed to run only from commands. If the user tries to run the interface ethernet 1', the user will get "failed command authorization.

  [2] press 'submit '.

  [3] Goto Group on which we want to apply these command authorization set. Select 'change settings '.

• series PIX command authorization

  Hi all

  can someone tell me please the use of GBA pix command authorization. I understand the use of a shell command authorization.

  I'm sorry if the question is too dumb. I am completely new to this sector.

  Thanks in advance.

  concerning

  Kirti.

  Pix command authorization set was designed to set up approval order with PIX/FWSM, as shell pix did not differ for IOS, but at the launch the actual code, PIX/FWSM seems to work correctly with the auth command sets the shell.

  So no one is really interested in using shell Pix more, more to watch new codes of pix it seems that developers are more likely making Pix Shell same shell IOS, so even if they stop PIX command sets in the next version of ACS I will not be surprised.

• The AAA command authorization

  I have an ACS 4.0 device. In the shell command authorization set section, you can define authorized or rejected orders (see) and arguments (running-config). I'm limiting users to a set of specific commands. One of the commands is "exit". To my knowledge, "exit" has no arguments. If I add 'Quit' as a permitted command but nothing come to the section of the argument, I get the authorization failed on the router. If I select "unparalleled stay args" (of output), the authorization is successful. I would prefer not to select "unmatched args to stay." Is there an argument for "out" I'm not aware of?

  Hello

  Try this,

  exit - permit

  represents returns the key.

  Kind regards

• 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.

• How can I use Cisco ACS to save Shell commands

  Hi guys, pleeeease how can I configure Cisco ACS to do command authorization on my Cisco 3660 router. I get the accounting logs and authentication but no newspaper that show orders issued by users - shell and it's the most important paper that I need. I read materails and download articles on the site of Cisco... but the thing is still does not give me the papers.

  I have these lines on my router:

  ...

  AAA authorization config-commands

  AAA authorization exec default group Ganymede +.

  AAA authorization commands 15 default authenticated if

  AAA authorization network default group Ganymede +.

  ...

  It's funny, when I turn on debugging of the authorization of the AAA on the router, it shows me every command being sent by the user on the debug log. But nothing shows under Administration TACAC + on the Cisco Secure ACS. What is responsible for this?

  *****************************************************

  I installed the trial version of the Cisco ACS 90 days and made all necessary settings and I have to say I like what I see already. I'm opening moves to recommend the product to purchase. Thank you guys, I got about the features of this ACS software through this forum, keep up the good work. I recommend the software for those who need to have adapted to the management reports Security Audit logs.

  If I understand what you're asking correctly, the answer is not in the authorization, that it is in accounting. I set up on my routers and send to ACS orders that level 15 privilege users enter on the router.

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

• Secure ACS Authentication and Authorization with SecurID

  I am able to authenticate connection attempts using an external database (RSA SecurID).  The problem is that everyone with a token is authorized to connect on any switch with priv15 or whatever I put (but no way to control who gets what access).  How can I allow users based on a certain type of belonging to a group?  The SecurID server is already integrated with LDAP, it only checks to see if the user exists in the database.

  I need to create two groups, or even only allow a single group and deny everyone, but anyone in the organization with a token is allowed to connect.  I can't find guides who do anything beyond authentication when you use a SecurID token.

  Thank you.

  Hello

  Have routers and switches, you given the command "authorization exec default group aaa GANYMEDE", it seems that you have only defined authentication on devices. When the control is in place, user access privileges may be governed by the ACS. In network administrator access by default policy (if you are using the default strategy for GANYMEDE), to set the authorization rule to verify membership in a user group and provide the appropriate profile of shell. Make the default rule to give DenyAccess shell profile to other users.

• App, opening a file via windows shell commands: "a device attached to the system does not work.

  Hello!

  I hope that someone here will be able to throw some lights on my question, if I post this is the wrong place please let me know because I was directed here (which forum? ). OK, I support and develop custom applications. An older application especially written in Delphi allows users to attached documents (pdf, jpg, txt, etc.) to the records of equipment in a data base. Later users can view these records of equipment and press a button to display the document.

  When the user presses the button to view the document, the application uses the folder variable to save the document to the temporary path and then asks windows via a shell command to open the file. The appeal of Delphi for windows used is the following:

  ShellExecute (GetDesktopWindow, 'open', PChar (TempFile), ",", SW_SHOWNORMAL);

  Normally this process works very well, we have had no problems so far. On a single computer (windows xp pro with Service Pack 3) belonging to a client, instead of opening the file, windows returns the system 31 error and the message ""a device attached to the system is not functioning. ". is displayed.

  * If I navigate to the location where the file is stored on the disk and try to open it, software adobe reader opens the file correctly.

  * I found some suggestions that the file extension is associated properly. PDF associated with Notepad, I changed, and the application could ask windows to open the file very well. Open the file from the location on the work of disc as well. Change the file for adobe and the problem persisted.

  * I reinstalled adobe reader software, but also a previous version of adobe and the problem persisted.

  * The application doesn't have any problem asking other files opened, only those associated with adobe reader on this same machine. The problem does not exist on other machines.

  That about sums up the problem. Any suggestion would be appreciated.

  Thank you

  Louis

  It was determined that the version of adobe reader was at fault.
